Title: Energy Gap – Refractive Index Relations in Semiconductors –

Implications in Bandgap Engineering

NM Ravindra | New Jersey Institute of Technology, USA

Abstract:

The ability to tailor the bandgap of semiconductors for a desired application offers numerous

opportunities for implementation in communications, energy conversion, microelectronics,

optoelectronics/photonics, thermoelectrics and related areas. This talk will focus on the role of

materials, material configurations and the resulting device structures. Several case studies

reflecting the role of bandgap engineering in a variety of industry sectors will be illustrated.

In each case, the role of the temperature dependence of bandgap and refractive index and its

contributions to the device performance will be described.

Title: Preparation of Protonic Ceramics from Polymer Clay

W. Grover Coors | Hydrogène Hèlix, SAS, USA

Abstract:

Protonic ceramics made from yttrium-doped barium zirconate, BaZr0.8Y0.2O3-d, (BZY20) for hydrogen

separation membranes are difficult to prepare by conventional powder sintering. However, this obstacle has been

overcome with solid-state reactive sintering (SSRS), where the precursor powders react in-situ during sintering

rather than being calcined to the pure phase in advance. This permits fabrication of high-density ceramics

suitable for the most demanding hydrogen separation applications. With SSRS, monolithic specimens may be

prepared by almost any conventional ceramic formation method, but an added benefit of SSRS is that, unlike

with traditional powder sintering, where high sintered density depends on high powder packing density of the

„green‟ bodies, dense BZY20 is easily prepared from bodies with a large fraction of organic binder. As a result, a

variety of non-traditional ceramic fabrication processes may be employed that enable production of complex

shapes by simple, low-pressure molding processes commonly employed in the production of fine porcelain.

Plastic bodies of polymer clay are described that demonstrate the utility and scalability of such processes for

fabricating ceramic components suitable for use in electrochemical devices, such as hydrogen separation

membrane reactors. The polymer clay method facilitates molding and joining complex shapes with differing

functions-–like thin-electrode-supported membranes, ceramic/metal composite electrodes, electrical

feedthroughs, and dense structural elements containing internal channels for gas manifolding. Furthermore, the

polymer clay method uses many of the simple tools and techniques commonly employed by ceramic hobbyists.

Solid state reactive sintering of ceramic proton conductors fabricated using polymer clay bodies has the potential

to disrupt fifty years of ceramic manufacturing orthodoxy and place in the hands of thousands of investigators

the means for making and testing innovative prototype devices.

Abstract:

Chronic consumption of water contaminated with arsenic in locations that do not have a water

treatment plant increases the risk of developing arsenic-related diseases. We have synthesized

a compound of CuO-ZnO, using the method of precipitation assisted by ultrasound, with the

ability to effectively remove the arsenic (III and V) from the water. The compound has been

characterized by techniques such as X-ray diffraction, scanning field emission electron

microscopy, in turn, the arsenic concentration was carried out using atomic absorption

equipment with graphite furnace. The compound used has a high arsenic adsorption capacity,

removing up to 10 ppm of arsenic (V) and 2.6 ppm of arsenic (III). The effect of pH and the

competition of ions such as chlorides, sulfates, and nitrates on the arsenic removal capacity of

water was also studied, observing that the working pH range of the compound is wide (pH 3-

11), for the arsenic (V), while the behavior in the removal of arsenic (III) decreases at basic

and acids pHs, showing its highest capacity at neutral pH. Coexisting ions do not significantly

affect the removal of arsenic (V), but they do affect the ability to remove arsenic (III),

reducing their efficiency by approximately 10%. The results of this research can contribute to

the challenges that currently exist in water pollution.

Title: Biomemristors based on Organic Materials

Niloufar RaeisHosseini | Imperial College London, UK

Abstract:

A memristor is a two-terminal device with a simple metal-insulator-metal structure and its

conductance is tuned by external inputs with a memory effect. A memristor is controlled by

internal state variables and input stimuli. Resistance switching random access memory

(ReRAM) is a category of memristor and has advantages of scalability, reliability, low power

consumption, and fast switching. ReRAM that use biodegradable organic materials as its

active film is a biomemristor and has the merits of flexibility, transparency, and compatibility

with various substrates. Compared to semiconductor devices, biomemristor is inexpensive and

easy to fabricate. Assimilation of biocompatible materials in ReRAM devices offers outlooks

to use them in biomedical aplications. I represent a robust, non-volatile, flexible, and

transparent biomemristor based on biopolymer. The source of the bipolar resistive switching

behaviour will be discussed in this talk. The set/reset behaviour in the memory device based

on biopolymer makes it suitable for use in neuromorphic devices.

Abdeen Mustafa Omer | University of Nottingham, UK

Abstract:

Globally, buildings are responsible for approximately 40% of the total world annual energy

consumption. Most of this energy is for the provision of lighting, heating, cooling, and air

conditioning. Increasing awareness of the environmental impact of CO2, NOx and CFCs

emissions triggered a renewed interest in environmentally friendly cooling, and heating

technologies. Under the 1997 Montreal Protocol, governments agreed to phase out chemicals

used as refrigerants that have the potential to destroy stratospheric ozone. It was therefore

considered desirable to reduce energy consumption and decrease the rate of depletion of world

energy reserves and pollution of the environment. This article discusses a comprehensive

review of energy sources, environment and sustainable development. This includes all the

renewable energy technologies, energy efficiency systems, energy conservation scenarios,

energy savings and other mitigation measures necessary to reduce climate change.

Title: Nanoparticles for the treatment of paediatric cancers

Helen Townley | University of Oxford, UK

Abstract:

In the UK 4500 children are diagnosed with cancer every year. The types of cancers that affect children can

be quite different to those affecting adults. Our research is focussed on nanoparticulate therapies for

rhabdomysarcoma, a soft tissue cancer, and glioblastoma a brain cancer. Using nanoparticles we can deliver

cancer drugs directly into cells. Nanoparticles can accumulate at the tumour site due to the enhanced

permeation and retention effect. This can minimize off-target effects by local release of the drug. In addition,

controlled release can result in the release of drug specifically at the site of action. We have also incorporated

nanoparticles into wafers that can be placed into the surgical bed after tumour removal. This permits slow

release of an anti-chemotherapeutic drug over several weeks to ensure that any remaining cancer cells are

mopped up.

We have used natural products as effective anti-cancer agents. However, the activity of the compounds can be

quickly lost due to their volatility. Encapsulation in nanoparticles can protect the compounds from

degradation and ensure their activity for much longer periods of time. In particular, the compounds citral and

ophiobolin have been used effectively against a number of different cell lines. Furthermore, we have shown

that nanoparticles can be made from the natural material itself. Melanin is a naturally occurring pigment in the

body which is involved in a range of functions from photosensitization, thermoregulation, protection from

radiation, and free radical quenching and metal iron chelation. Iron is needed in much greater amounts by

cancer cells for their rapid proliferation. Chelation of iron in the total body would be detrimental since it is

needed by all cells in the body for proper function. However, melanin nanoparticles can be localized to the

tumour and deplete the cancerous cells of iron, resulting in cell death.

Title: Identification and first steps of characterization of a promising new

heat storage material for high temperature applications

Fouzia Achchaq | Bordeaux University, France

Abstract:

Industrial sectors such as those of metallurgy, ceramics, glass, concentrated solar thermal energy, chemistry

and so on have now to seriously consider thermal energy storage as a key part for a successful broad energy

mix achievement. Otherwise, it will be indeed very difficult to take advantage of each cutting-edge

technology to carry out a low-cost and efficient energy transition. Until now, the choice of materials to be

used in the storage units with a working temperature range varying from 300 to 600°C has been directed to

the phase change materials. These latter are mainly eutectic compositions showing the advantage of behaving

like pure substances: their fusion is congruent and occurs at a constant temperature. However, the phase

diagrams theoretical study of salt-based binary systems has shown that stoichiometric peritectic compounds

have, on average, energy densities two to three times higher than those of phase change materials (molten

salts) used in existing concentrated solar power plants, such as Archimedes in Italy for instance. This

performance is related to a reversible chemical reaction occuring in addition to the solid/liquid transition

during the thermal energy discharge process of the material.

On the one hand, this work focus thus on these advanced energy materials for ultra-compact thermal energy

storage at high temperatures (300-600°C) that can provide, at almost constant temperature and ambient

pressure, a potential energy density much higher than that of the pure and eutectic materials. This is due to

their capacity to combine all advantages provided by sensible, latent and thermochemical processes. On the

other hand, this work presents more specifically the case study of the Li4Br(OH)3 peritectic compound

selected from the LiOH/LiBR phase diagram as a highly promising candidate for heat storage applications at

around 300 °C with an outstanding energy density of 434 kWh/m3.

Title: In situ HT-SEM study of the synthesis process of a promising new

heat storage material

Philippe Legros | PLACAMAT, France

Abstract:

This study is performed in the framework of ANR-Pc2TES project dealing with the development of the

peritectic compounds as new thermal energy storage materials for temperatures varying from 300 to 600°C,

which allows covering a wide spectrum of applications. The peritectic microstructure development is much less

understood than single-phase or eutectic solidification processes. The level of comprehension drops drastically

about ionic alloys such as LiBr/LiOH binary systems. Besides, Li4Br(OH)3 performances depend strongly on a

complex interplay between the initial composition, the imposed temperature gradients, the operating

surrounding atmosphere and the solid fraction growth velocity. As a consequence, Li4Br(OH)3 heat energy

storage potential may be strongly affected. The objective of this work is hence to participate to an in-depth

understanding of the Li4Br(OH)3 formation process by establishing the critical links between the processing

conditions and the final microstructure formation. To do so, the influence of working parameters such as the

nature of the surrounding atmosphere, cooling rates and thermal gradients and so on is studied by using a hot

stage placed inside the scanning electron microscope chamber.

The first results of the in situ and real-time experiments performed on LiBr, LiOH and Li4Br(OH)3 at

secondary vacuum and then, at a nitrogen-rich environment at microscale are presented and discussed. The

thermally-induced transitions of the starting materials LiOH and LiBr have been observed highlighting the

LiOH decomposition process into Li2O. The Li4Br(OH)3 morphology, validated by X-ray diffraction tests, are

then compared to that obtained at the end of the ex situ synthesis by using the standard thermal treatment. These

results have also proven to be very useful to better understand those obtained by using the differential scanning

calorimeter afterwards.

Title: Effect of textiles’ surface on the properties of conducting polymers

composites deposited onto textile through 3D printing

Prisca Aude Eutionnat-Diffo | GEMTEX – Laboratoire de Génie et Matériaux Textiles, France

Abstract:

Thermoplastic Conducting Polymers Composites (CPCs) deposited onto textiles through 3D

printing and more specifically Fused deposition Modelling (FDM) process are recently used to

develop smart textiles for various applications. 3D printing is a technology which can exhibit

ease of processing, low cost and versatility and low waste of material. The durability and

flexibility the CPCs applied on textile materials through 3D printing are important to consider

in the development of comfortable and durable smart textiles via FDM process. For this reason,

adhesion, stress and strain at rupture, deformation and abrasion resistance of these materials

need to be optimized and understood. In this study, the influence of the textiles‟ surface

characteristics on the properties of the CPCs deposited onto the textiles is approached. Indeed,

the surface of the different textile materials was characterized by measuring their roughness and

porosity; and then linked to the adhesion, the stress and strain at rupture, the deformation and

the abrasion resistance of the 3D printed CPCs onto textiles through statistical models. Based

on these models, each of these properties was optimized. It was found that higher roughness

and porosity led to better adhesion and stress at rupture but lower wear resistance (abrasion)

and deformation. These findings are important in the development of smart textiles through

FDM process.

Title: Preparation of n-hexadecane/polycaprolactone microcapsules via

single electrospraying and coaxial electrospraying: comparison of their

formation, structure and properties

Shengchang Zhang | GEMTEX – Laboratoire de Génie et Matériaux Textiles, France

Abstract:

Phase change materials (PCM) can release (or store) a large amount of latent heat when the surrounding temperature is

lower than its crystallization point (or higher than its melting point). Thus, PCM is widely applied in thermal management

and energy storage in textile sector. More meaningfully, when PCM is encapsulated into shell matrix, not only the leakage

of PCM during its phase transition can be effectively prevented, but also the thermal conductivity of PCM can be

improved significantly. Meanwhile, the durability of phase change microcapsules (mPCM) can be also prolonged.

Fabricating and designing mPCM with a core-shell structure have attracted more and more attention.

Electrospraying, as a green and high-efficiency electrohydrodynamic atomization technology, has a great advantage and

potential to fabricate microspheres or microcapsules. One of the main benefits of the use of the electrospraying route in

preparation of mPCM is the control of the structure and properties of mPCM via adjusting the operating parameters as

well as solution properties. Among a series of operating parameters, using different electrosprayed nozzles can result in

different morphoogies and thermal properties from electrosprayed mPCM. Thus, on the one hand, the formation of Taylor

cone and the break-up process of charged droplets depend on the kind of electrosprayed nozzle used. On the other hand,

the diffusion of PCM and the evaporation of solvent during the flight process of electrosprayed droplets obtained from

different nozzles are also different. Therefore, it is interesting to investigate the effects of nozzle geometry on the

structure and properties of electrosprayed mPCM. In this study, a single nozzle and a coaxial nozzle were applied to

synthetize n-hexadecane/polycaprolactone microcapsules. The size and morphology of electrosprayed microcapsules were

characterized by scanning electron microscopy (SEM) and optical microscopy (OM). The core-shell structure of

electrosprayed microcapsules was analyzed via transmission electron microscopy (TEM). The thermal behaviour and

thermal degradation were studied via differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA).

From these experimental results, the comparison between the use of a single or coaxial nozzle in the preparation of

electrosprayed mPCM with different structures and properties was realized.

Title: Influence of degree of filling on mechanical properties of PLA

obtained by 3D printing methods

Anna Gawel | Cracow University of Technology, Poland

Abstract:

The introduction explains the basic terms of method of production, crystallization

and hydrolytic degradation of polylactide and their meaning for changing the properties

of this material. Samples employed in this investigations were made of polylactide acid using a 3Dgence

printer. Half of the specimens were subjected to crystallization process (C), which consisted of annealing in

heating chamber at 80 degrees of Celsius for 2 hours and then slowly cooling. The study part of the paper

presents the assessment of the impact of the degree of filling of samples (constant print angle 45 deg) made of a

polylactide filament by 3D printing on the basic physico-mechanical properties before and after the hydrolytic

degradation process and the effect of crystallization on the change of properties at the high temperature. From a

number of tests of strength properties of the material, it was found that samples with a lower degree of filling

have much worse results of strength tests. The formation of crystalline lattices significantly increases the

discussed parameters and hydrolytic degradation in most cases weakens the sample.

The degree of filling of the sample has a major impact on the strength properties of the samples. A smaller

printing angle generates a shorter printing time and decrease in density. Performing crystallization of the

sample improves its strength and modulus of elasticity, and slightly reduces deformation at break, especially in

the elevated temperature range. Hydrolytic degradation reduces the effect of crystallization on the obtained

strength properties.

Title: Investigating the Effect of Doping TiO2 Compact Layer by Cu Ions

for High Performance Perovskite Solar Cells

Alaa Ahmed Zaky Hussein | National Center for Scientific Research, Greece

Abstract:

Perovskite solar cells (PSCs) have been recently developed as the most promising alternative to silicon-based

counterparts. In the n-i-p configuration, the electron transporting layer (ETL) plays a vital role in the power

conversion efficiency (PCE) of PSCs. High electron mobility and conductivity of the ETL, especially when it is

a compact one, are necessary towards highly performing PSCs by reducing excessive charge accumulation and

guaranteeing effective electron passage to the ETL/perovskite interface.

Contact angle measurements confirmed that the introduction of copper ions (Cu2+

) into the compact TiO2 layer

increased its hydrophobicity, thus favoring improved perovskite crystallization, a fact corroborated by XRD

analysis. The trap-filled limit voltage (VTFL) for FTO/ETL /MAPbI3/PCBM/Ag devices shows a significant

decrease with the Cu-TiO2 compact layers, which is associated with lower traps density for the corresponding

perovskite film. Moreover, the doping of Cu2+

in TiO2 also affects the photovoltaic properties (Figure 1).

Indeed, a PCE higher than 18% was obtained for the PSCs with the optimal Cu+2

concentration together with

open circuit voltage (Voc) of 1.1 V, current density (Jsc) of 23.15 mA·cm−2

, and a fill factor (FF) of 73%. These

modified cells outperform the performance of the reference device (using the TiO2 ETL) showing a PCE equal

to 15.78% (with Voc equal to 1.07 V, Jsc of 20.87 mA cm−2

, and FF equal to 70 %). Finally aging tests realized

under controlled under controlled conditions confirmed that the copper-doped devices showed higher stability

in comparison with the non-doped ones.

Title: Determination of the wave parameters of the gravitational field and

their confirmation

Valentyn Nastasenko | Kherson state maritime academy, Ukarine

Abstract:

An analytical analysis of the gravitational constant G = 6.6739010-11

m3/(kgs

2), in the

framework of its dimension, which is associated with Planck‟s values of length, time and mass,

showed that a frequency can be distinguished in it. In further works, it was associated with the

frequency of oscillations of the waves of the gravitational field νG = 7.41042

s-1

(Nastasenko

constant). Its use, within the framework of the wave function λG = с/νG, made it possible to

determine all other parameters of the gravitational field: wavelength

λG = 4.051249410-35

m, amplitude AG = λG = 4.051249410-35

m, period TG = 13.5|135|10-44

s,

energy EG = 4,90329109 J.

On this basis, the force of action of the gravitational field was determined. For the Earth, its use

made it possible to determine the acceleration of gravity through the found wave parameters of

the gravitational field. The results obtained completely coincide with the

g = 9.81 m/s2 value determined through the interaction of the masses according to Newton‟s

law of universal gravitation. A similar coincidence of the results was obtained for the attractive

forces of the moon, the sun and other objects of the solar system found through the wave

parameters of the gravitational field and according to Newton‟s law.

Thus, the reliability of the proposed wave parameters of the gravitational field was strictly

proved.

Title: Physical Modelling of Metallic Droplet Breakage and Coalescence in

Molten BOF Slag

Muxing Guo | KU Leuven, Belgium

Abstract:

In order to understand better the droplet behavior during a slag treatment process, a physical

modeling was established using the similarity principle. The physical modeling consisting of

single factor and orthogonal experiments was performed in a transparent vessel model with a size

ratio of 1:4 at room temperature. Paraffin oil, 20 wt.% copper culfate solution and compressed air

were used to simulate molten slags, metallic droplets and carrier gas, respectively. The droplets

injected into the system during the experiment were captured by a high speed camera and were

analyzed by Image Pro Plus software to obtain the droplet size distribution. The droplet size in

the physical modelling and slag treatment process is quantitatively correlated. The physical

modelling observation shows that the breakage and coalescence of the droplets occur at different

conditions, however, the droplet breakage phenomenon is dominant over its coalescence in the

current industrial hot-stage slag treatment practice. Droplet breakage is enhanced with increasing

gas flow rate and/or lance depth. No significant effect of the nozzle configuration was found on

the breakage and coalescence of the droplets. The droplet size distribution varies with the lance

position. The results from orthogonal experimentation show that gas flow rate and lance depth are

the most important factors for droplet breakage, the extent of which can be reduced through a

proper selection of the operational conditions. A linear relationship between the droplet size and

the input energy is obtained.

Title: Specific features of the crystallinity and morphology in designing

materials for targeted applications

Lucian Baia| Babeș-Bolyai University , Romania

Abstract:

Nowadays, it is widely accepted that a deep understanding of the morphological and structural characteristics of the used

(nano)structures is needed for obtaining a maximum efficiency for a desired application. The type of the structure, e.g.,

crystalline, amorphous, etc., its shape and size are key issues in designing novel materials with tuned properties. The present

work is dealing with a selection of such topics. The first one relates about the influence of morphological particularities of

anatase titania crystals on the photocatalytic efficiency to decontaminate chemically polluted water. The shape controlled

titania microcrystals obtained hydrothermally in the presence of carbon nanotubes, with a high amount of the most reactive

{001} facet, were investigated. The developed holes and other significant structural alterations observed after samples

calcination were found to enhance the photocatalytic activity of titania crystals. The causes that generated the noticed

improvements were also analyzed.

The second topic is dealing with hierarchical TiO2 nanostructures synthesized by hydrothermal method by involving two

precursors, namely tetraisopropyl orthotitanate (TTIP) and tetrabutyl orthotitanate (TBU), It was found that their structural

and optical properties are dependent on the synthesis parameters and the developed TiO2 crystalline systems‟ crystal phase

distribution and the morphology are very sensitive to the composition of the solvothermal system. The TBU samples

exhibited higher conversion rate in photodegradation of an etalon pollutant.

The third topic reports about the graphene oxide (GO) based membranes as important materials used in smart technologies

and applications. Free-standing graphene oxide (GO) membranes were developed by involving a scaled-up, non-toxic, and

low cost self-assembly process. The tunability of the morphological, structural and optical properties of the membranes was

achieved by using different self-assembly time. A structural model for the membrane formation during the self-assembly

process was also proposed taking into consideration the structural and morphological differences (i.e. sheet size, surface

chemistry and surface charge) between the three-sorted GO fractions.

Title: Impact of ionizing irradiation on LEDs during operation

Alexandr Vasilevich Gradoboev | Tomsk Polytechnic University, Russia

Abstract:

Radiation technologies allow to control in a guided way of semiconductor devices parameters. The purpose of this

work is to develop of radiation technologies aimed at improving of radiation resistance and reliability of LEDs

based upon AlGaAs double heterostructures. The objects of this investigation were industrial LEDs manufactured

on the basis of dual AlGaAs heterostructures with 5 μm active layer grown on the monocrystalline n-GaAs wafer

by means of liquid epitaxy. Characterized parameters of LEDs were taken using an automated measurement

complex with spherical photometric integrator. Irradiation by static gamma-quanta was carried out on a stationary

installation based on cobalt-60 isotope. The level of exposure was characterized by absorbed dose (Gy). The level

of exposure was characterized by neutron fluence Fn (cm-2). The reliability was estimated by results of step-by-

step tests. The parameters of LEDs were measured before, after irradiation and after every step of accelerated

tests. The research of radiation resistance and reliability of LEDs based upon AlGaAs are presented. Radiation

model is developed according to these results. It describes the changes of emissive power by three distinctive

stages. Reliability model is developed identically to radiation model. The influence of preliminary irradiation of

LEDs by gamma-quanta and fast neutrons on their further radiation resistance is observed. Preliminary irradiation

allows to significantly improve the radiation resistance of LEDs due to increase of ohmic contacts resistance and

radiation-stimulated reconstruction of the initial defect structure of the LED crystal. The represented “memory

effect” of the radiation influence is observed for other types of semiconductor devices. Choice of optimum

preliminary irradiation level of LEDs allows to increase the reliability of ohmic contacts, to reduce the rate of the

emissive power decrease and the probability of catastrophic failure.

Proposed technologies can be recommended for other types of semiconductor devices.

Title: Stress Relaxation of Composites with Nano-enhanced Resin after

Low Velocity Impact Loads

Paulo Nobre Balbis dos Reis | University of Beira Interior, Portugal

Abstract:

Carbon fibre composites offer an attractive potential for reducing the weight of high-performance structures as consequence

of their high specific strength and stiffness. These materials offer excellent in-plane performance, but they have inferior

through-thickness properties, where, in case of impact loads, various types of damages can occur. These damages are very

dangerous because they are not easily detected visually, and they can affect significantly the residual properties and

structural integrity of those materials.

In order to improve the impact strength, literature suggests the nanoscale reinforcements as a good strategy, because they,

simultaneously, increase the mechanical performance and thermal properties. In terms of impact performance, the reduced

damage zone size observed is attributed to the increased stiffness and resistance to damage progression of the nanophased

laminates. However, polymer composites are prone to creep and stress relaxation as consequence of the inherent

viscoelasticity of the matrix phase, which is a great challenge when they are used in long-term applications.

Therefore, the main goal of this work is to study the stress relaxation behaviour of carbon laminates with an epoxy resin

enhanced by carbon nanofibers (CNF). Firstly, different percentages in weight were used to obtain the best flexural strength

and impact resistance. It was possible to conclude that, for both properties, the ideal amount was 0.75% by weight. For this

value, stress relaxation tests were performed, and the results obtained compared against the laminates with neat resin. In

both systems the stress decreases with the time, however, this decrease is more pronounced for laminates with neat resin.

The same tendency was observed for laminates subjected to impact, but the existence of impact damages in the composite

increases the overall relaxation. Therefore, more relaxation was observed for higher impact energies as a consequence of

greater damages. Finally, the results were fitted following the Kohlrausch-Williams-Watts equation, evidencing good

accuracy of the model for the stress relaxation time.

Title: Chromium doped alumina usability in dosimetry

Ernests Einbergs | University of Latvia

Abstract:

Study of radiation induced electronic processes in materials precipitated a now widespread

material science field called dosimetry, which specializes in ionizing radiation detection and

quantification. The performance of most materials used for dosimetry applications is mainly

governed by the impurity ions in the crystalline lattice coupled with lattice imperfections around

them (with a meaningful difference in size or oxidation state compared to host ions). In this study,

we explored augmentation of luminescent properties of alumina caused by chromium ion doping,

with a goal of increasing the quantity of charge carrier traps in the crystalline lattice. Porous

microparticles synthesized with sol-gel method displayed higher thermoluminescent

response compared to that of a single crystalline ruby. We have found that 0.2 wt% of

yielded the highest XRL and TSL readout of all the studied additive concentrations added to

alumina during synthesis. Our results display a promising use case for Cr doped alumina.

Conducted study provides information on a new alternative to already existing ionizing radiation

dosimetric materials with desirable physical and chemical properties as well as relatively lowers

manufacturing cost.

Title: Temperature Dependent Interplay between Emitting Species in

Highly Ordered Poly(thiophenes) as Revealed by Optical Spectroscopy

John Onyango Agumba | Jaramogi Oginga Odinga University of Science and Technology

Abstract:

In this study, the temperature dependent PL spectra measurement has provided us a feasible means to elucidate

the nature of the emissive species and the melt transitions in different polythiophenes. The effects of thermal

fluctuation on different phases of a bulky substituted poly (3-(2, 5-dioctylphenyl) thiophene) (PDOPT) and Poly(3

hexylthiopne-2 5diyl) (P3HT) have been systematically investigated using photoluminescence spectroscopy. This

has been achieved by performing in-situ temperature dependent photoluminescence measurements followed by

detailed spectral analysis. For PDOPT, the intensities of the emitted species varied as a function of temperature

that determine degrees of order. Well-ordered crystals emitted strongly in lower energies as opposed to less

ordered films and spherulitic crystals. From the deconvoluted PL spectra, it was revealed that, the emitting

energy bands remained constant with shift of intensity with ordered crystals emitting strongly in higher

wavelengths as compared to their disordered counterparts that emit strongly in lower wavelengths. On the other

hand, for P3HT, the spectrally resolved PL lineshapes through multipeak Gaussian functions simulating 0-0, 0-1,

0-n peaks have revealed multiple vibrational replicas yielding different emitting species (states). We suggest that

the temperature dependent vibronic progressions arise from different electronic origins i.e. different species

(fluorophores) due to multiple crystalline polymorphs within the crystal with varied coupling of the excited states.

From our observation, we conclude that it is not sufficient to invoke only the intramolecular interactions in

explaining the nature of PL spectra of highly ordered polythiophenes which are widely dominated by both

interchain and intrachain interactions.

Title: Nature of chemical elements

Henadzi Filipenka | Independent researcher

Abstract:

The main problem is that using X-ray to determine the crystal lattices of different materials, and

why they are such and not others is not yet known. For example, copper crystallizes in the fcc

lattice, and iron in the bcc, which upon heating becomes fcc and this transition is used in the heat

treatment of steels.

The literature cites many factors affecting the crystallization of atoms, so I decided to remove

them as much as possible, and the metal model in the article, let‟s say, ideal, i.e. all atoms are the

same (pure metal) without inclusions, without implants, without defects, etc., using the Hall effect

and other data on the properties of the elements, as well as Ashcroft and Mermin's calculations -

the main determining factor for the type of lattice was the external electrons of the atom‟s core or

ion that turned into as a result of the transfer of part of the electrons of the atom to the conduction

band of the crystal.

It turned out that the metal bond is caused not only by the socialization of electrons, but also by

the external electrons of the atomic cores, which determine directivity or type of crystal lattice.

A change in the type of metal lattice can be associated with the transition of an electron into the

conduction band or its return from this band.

Title: Graphene Coatings: A Disruptive Approach to Durable Corrosion

Resistance

Raman Singh | Monash University, Australia

Abstract:

Corrosion and its mitigation costs dearly (any developed economy loses 3-4% of GDP due to corrosion, which

translates to ~$250b to annual loss USA). In spite of traditional approaches of corrosion mitigation (e.g., use of

corrosion resistance alloys such as stainless steels and coatings), loss of infrastructure due to corrosion continues

to be a vexing problem. So, it is technologically as well as commercially attractive to explore disruptive

approaches for durable corrosion resistance.

Graphene has triggered unprecedented research excitement for its exceptional characteristics. The most relevant

properties of graphene as corrosion resistance barrier are its remarkable chemical inertness and impermeability

and toughness, i.e., the requirements of an ideal surface barrier coating for corrosion resistance. However, the

extent of corrosion resistance has been found to vary considerably in different studies. The author‟s group has

demonstrated an ultra-thin graphene coating to improve corrosion resistance of copper by two orders of

magnitude in an aggressive chloride solution (similar to sea-water). In contrast, other reports suggest the graphene

coating to actually enhance corrosion rate of copper, particularly during extended exposures. Authors group has

investigated the reasons for such contrast in corrosion resistance due to graphene coating as reported by different

researchers. On the basis of the findings, author‟s group has succeeded in demonstration of durable corrosion

resistance as result of development of suitable graphene coating. The presentation will also assess the challenges

in developing corrosion resistant graphene coating on most common engineering alloys, such as mild steel, and

presents results demonstrating circumvention of these challenges.

Title: Large scale platforms for energy photoelectrocatalysis at Silicon-

based nanomaterials

Ahmed Farid Halima | RMIT University, Australia

Abstract:

Realizing a green economy envisages solar-to-fuel (STF) conversion as the promising pathway

for reliable energy storage and utilization. To facilitate this, efficient catalysts are optimized for

nanostructured semiconductors towards highly performing devices. Silicon is regarded an

advantageous photoelectrode support for a range of fuel reactions, provided enhancement to its

chemical stability. One challenge prevails for nanostructured Silicon-based devices; to identify

scalable and reliable chemical fabrication methods, especially for noble or earth-abundant metal

catalysts (such as Pt, Pd, Au, Ag, Cu) for respective/simultaneous photocatalysis of Hydrogen or

Carbon Dioxide. The work presented herein demonstrates detailed investigations for cost-

effective, reliable and scalable nanofabrication processes, and display device

functionality/efficiency characterization in STF conversion.

Title: Circular Materials for a Circular Economy

Maryam Naebe | Deakin University, Australia

Abstract:

Materials designed for multiple life cycles are required for a circular economy. With constant

novelty and evolution in material science and engineering, no longer we can keep adding

functionality via tailored complexity for a single life. Superior fit-for-purpose materials must

retain maximal value through all their subsequent applications. Much effort has been expended on

how to best recycle, reuse and re-purpose our existing materials. This talk will focus on finding

more sustainable solutions to build multiple life functionality into new materials. While the focus

is on designing out textiles waste, a several case studies will be discussed to show case the

creating novel ways to maximise value from waste.

Title: Shape-memory Polymers for Biomedical Applications

Mitsuhiro Ebara | National Institute for Materials Science (NIMS), Japan

Abstract:

Shape-memory polymers (SMPs), which have the ability to return from a deformed state to their

original shape after receiving an external stimulus, have drawn much attention during

fundamental research into practical applications. We have been developing a thermally induced

SMPs switch with a Tm at a biologically relevant temperature using cross- -

caprolactone) (PCL). PCL is an important biocompatible and biodegradable synthetic polymer

and has been approved for biomedical applications by the US Food and Drug Administration

(FDA). In recent years, our laboratory developed SMPs that respond not only to heat but also

light and magnetic field. We also succeeded in providing shape memory properties with

applications such as nanofiber meshes, nanoparticles and 3-dimentional scaffold materials.

in Pakistan and Japan.

Title: Artificial blood vessel scaffolds of biodegradable co-polyester

nanofibers for cardiovascular regeneration

Sofia El-Ghazali | Shinshu University, Japan

Abstract:

The isosorbide bio-based polyesters Poly (1,4-Cyclohexane Dimethylene Isosorbide

Terephthalate) (PICT) and Poly (Ethylene Glycol 1,4-Cyclohexane Dimethylene Isosorbide

Terephthalate) (PEICT) are being widely investigated with a view to exploring more functional

and biomedical applications. However, nanofibers made of PICT/PEICT blend (BLEND) have

not been manufactured yet. Herein, we report three-dimensional (3D) artificial blood vessels

(ABV) using PICT, PEICT and BLEND nanofibers with three different cross-sectional diameters

≤2 mm which remain a big challenge. Scanning Electron Microscopy (SEM) showed smooth

morphology of the ABVs and Atomic Force Microscopy (AFM) clearly showed compacted

nanofibers on the surface of BLEND which has more potential to hold the human breast cell

compared to PICT and PEICT. Fourier Transform Infra-Red spectrum (FTIR) showed that no

significant difference was found between PEICT and the BLEND chemical structure. Enzymatic

degradation showed the higher degradation rate of BLEND compared to PICT and PEICT. The

ABV of the BLEND has a capability to adopt the tensile properties of both PICT (stress) and

PEICT (strain) and it showed intermediate tensile strength. The results demonstrated that the

human breast cell can be cultured successfully on the BLEND.

Title: Inventive Pressure-Mediated Electrophoretic Deposition of

Antibiotic-Laden Polymer Nanocomposite Films for Surface Modification of

Titanium Implants

Mojtaba Mansoorianfar | Nanjing Forestry University, China

Abstract:

We present, for the first time, a novel procedure based on electrophoretic (EPD) under isostatic

pressure to control the deposition rate of multicomponent thin films. A uniform composite thin

film (thickness ~ 100 nm) could be deposited on a Ti-based substrate under low pressure of 10-2

mbar (LP), atmospheric pressure (AP), and high pressure of 5 bar (HP). Surprisingly, results

showed that increasing pressure on the suspension during electrophoretic (PM-EPD) had

increasing effect on the current density within time evolution. The results of TGA showed that at

AP larger amounts of CNF and alginate were deposited on the surface compared to LP or HP.

However, highly amount of BG could be deposited at LP. Moreover, FTIR, and SEM

characterizations proved that the deposition rate of film increases at AP; it enhances the coating

thickening. While the amount of released drug from the surface of samples synthesized in HP was

higher than AP and LP. As a result applying vacuum eliminated nanobubbles inside the composite

and decreased the amount of loaded drug. By altering the pressure to vacuum, pH decreased to

near 8 which decreased OH- ion concentration, zeta potential of suspension, and deposition rate of

coating. While rising pressure traps nanobubbles inside the composite, increase resistance of layer

and prevent thickening of coating. These bubble-like holes play as drug storage. In vitro

bioactivity assessment using MTT assay and 3-days drug releasing from the composite films

exhibited enhancement in biocompatibility, viability and promotion in drug releasing by increasing

pressure.

Title: Semiconducting Polymers for High-Performance Field-Effect

Transistors

Yunqi Liu | Chinese Academy of Sciences, China

Abstract:

During the past several years, impressive progresses have been made in organic field-effect

transistors (OFETs), particularly in conjugated polymer-based FETs. A few high-performance

polymers-based FETs have been developed with a remarkable mobility of more than 10 cm2 V

−1

s−1

, which provides a promising opportunity for applications in flexible displays and wearable

devices.

In this presentation, several design ideas for high-performance semiconducting polymers are put

forward and discussed. Following these guidelines a few copolymers with D−A structures

exhibiting p-tpye, n-type and ambipolar behaviour were synthesized. Their transporting properties

in FETs were measured and studied.

Title: Distribution of Multimaterials with Nanoscale Resolution guided by

Microtopographic Substrate

Jia Zhang | Harbin Institute of Technology, China

Abstract:

Distribution of multi-materials at arbitrary positions with nanoscale precision and over large area

substrates is essential to future advances in functional graded materials. Such stringent

requirements are highly beyond the reach of current techniques although the newly developed 3D

printing technologies are addressed. Here, a radial gradient circle array film is fabricated by using

microtopographic substrate guided with the distribution accuracy up to ~18 nm. A mathematical

model is developed to guide the distribution of position, size, shape, type of materials on an

arbitrary section for the given morphology of substrate. The periodic electrical and mechanical

properties of the radial gradient circle film are identified, which will be benefit for further

functionalization and applications, such as gradient refractive index lens, microcoils, local

catalysts.

Title: Nanotribology of metals and alloys

Arnaud Caron | Korea University of Technology and Education, Republic of Korea

Abstract:

In this work we apply atomic force microscopy to investigate the response of single asperity

sliding contacts between AFM tips and metals and alloys. As involving at least two bodies the

friction response of a tribological system is complex and may include chemical, structural and

mechanical effects.

We find that sliding friction is both affected by chemical and structural effects. Chemical

contributions were tested by changing the metallurgical affinity between the involved metallic

couples. For non-affine metallurgical partners sliding friction is governed by simple shearing while

the sliding response of affine partners is governed by adhesion and local alloying. In contrast we

find that the sliding friction of an amorphous alloys is strongly affected by its structural relaxation

state. Further, metals and alloys wear in unlubricated condition closely relate to their plastic

deformation. We investigated the tribological response of different fcc metals and their alloys: Au,

Ag, Ni, Ag-Cu eutectic alloys and age hardening Al-Cu alloys. While wear and ploughing friction

coefficient of pure fcc metals scale with their hardness, we demonstrate how the tribology of

metallic alloys varies with their microstructural length scale. Further, investigating the tribological

response of single asperity contacts allows monitoring the mechanisms involved in friction and

wear.

Title: Characterization of sodium caseinate/Hydroxypropyl methylcellulose

concentrated emulsions: Effect of mixing ratio, concentration and wax

addition

Kooshan Nayebzadeh | Shahid Beheshti University of Medical Sciences

Abstract:

The effects of mixing ratio (1:1, 2:1 and 4:1 sodium caseinate:hydroxypropyl methylcellulose,

CN:HPMC), HPMC concentration (0, 0.6 and 1.2 wt%), CN concentration (0, 1.25 and 2.5) and

beeswax addition (3%) on the physical stability of concentrated O/W emulsions (φoil = 0.6) were

investigated. The emulsion stability, particle size distribution, microstructure and rheological

properties were measured. The results showed that emulsion stability was significantly improved

with increasing HPMC concentration (pvalue < 0.05). The samples with the highest and the

lowest biopolymers concentration at mixing ratio of 2:1 had the highest and the lowest ESI (98%

and 48%), respectively. In addition, the most stable sample had the smallest volume mean

diameter and approximately desirable rheological properties. The beeswax addition considerably

improved rheological properties whereas increased droplets diameter and emulsion instability. In

summary, concentrated emulsions stabilized by caseinate/Hydroxypropyl methylcellulose complex

may be useful for application in particular food such as heavy cream, mayonnaise, oleogels and

pharmaceutical products.

Title: Highly efficient removal of Rhodamine B by MIL-100(Fe)

@Fe3O4@AC

Asma Hamedi | Yazd University

Abstract:

A new magnetic nanocomposite called MIL-100(Fe) @Fe3O4@AC was synthesized by the

hydrothermal method as a stable adsorbent for the removal of Rhodamine B (RhB) dye from

aqueous medium. The size of these nanocomposite is about 30–50 nm. Compared with activated

charcoal (AC) and magnetic activated charcoal (Fe3O4@AC) nanoparticles, the surface area of

MIL-100(Fe) @Fe3O4@AC were eminently increased while the magnetic property of this

adsorbent was decreased. The surface area of AC, Fe3O4@AC, and MIL-100(Fe) @Fe3O4@AC

was 121, 351, and 620 m2/g, respectively. The magnetic and thermal property, chemical structure,

and morphology of the MIL-100(Fe) @Fe3O4@AC were considered by vibrating sample

magnetometer (VSM), thermogravimetric analysis (TGA), zeta potential, X-ray di_raction (XRD),

Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Brunner-

Emmet-Teller (BET), and transmission electron microscopy (TEM) analyses. The relatively high

adsorption capacity was obtained at about 769.23 mg/g compared to other adsorbents to eliminate

RhB dye from the aqueous solution within 40 min. Studies of adsorption kinetics and isotherms

showed that RhB adsorption conformed the Langmuir isotherm model and the pseudo second-

order kinetic model. Thermodynamic amounts depicted that the RhB adsorption was spontaneous

and exothermic process. In addition, the obtained nanocomposite exhibited good reusability after

several cycles. All experimental results showed that MIL-100(Fe) @Fe3O4@AC could be a

prospective sorbent for the treatment of dye wastewater.
