Preface

That the mastery and control of advanced materials technologies will lead to dominate in several high technology field and major segments of manufacturing, was best understood in Japan and their advanced material programme have been in place since the early eighties. In the USA, several experts have identified advanced materials as most important issue facing the economy in the 1990s. During the same period India realised requirement of devising long run material strategies and Prof. C.N.R. Rao, FRS, the doyen of Indian Science and Technology, founded Materials Research Society of India (MRSI), in 1989 as an interdisciplinary society committed to stimulate and integrate the research in the field of materials to cope with the rapid industrial progress in the country. Pursuant with this mission MRSI organises various programmes and two days Materials Conclave followed by two days Annual General Meeting, is one of such events, held every year at the different parts of the country, where materials scientists and engineers from across country and abroad gather together to open dialogue on the impending issues related to materials. In this backdrop the 2nd Materials Conclave and 31st Annual General Meeting, being hosted by MRSI, Kolkata Chapter in collaboration with CSIR-Central Glass & Ceramic Research Institute, Kolkata and in association with MRSI, Kharagpur Chapter during February 11 to 14, 2020 at CSIR-Central Glass & Ceramic Research Institute, Kolkata, to provides a unique opportunity to materials scientists and research scholars to present their research and developmental activities. Plenary, Invited Talks by many distinguished experts, particularly in the aspects of basic understanding, development and exciting new application prospects are the major focus of the four-day programme. In addition, there will be special award lectures, medal lectures and poster presentations by young researchers. Let the conference have its take-off! Meanwhile we extend our sincere thanks and gratitude to all the guests, participants, speakers, sponsors, collaborator, supporters and advertisers for their kind patronage and valued cooperation to make the conference a grand success. Special thanks are due to the chairpersons and team members of the scientific and organising committees, whose untiring effort and relentless contribution have made this conference a reality. Our sincere thanks are also due to the persons behind the scene, but for whose silent contributions this conference would not have been a success. N. R. Bandyopadhyay Mrinal Pal Arijit Sinha Conference Chair Conference Secretary Conference Convenor

Studies on Lithium Ion Batteries are of great importance in view of their potential applications in portable power devices including electric/hybrid electric vehicles. In order to find novel materials and also improve the performance of several known materials, we have synthesized variety of materials by solid state-, chemical- and physical- methods. Their Physical and Electrochemical properties were evaluated using different techniques including cyclic voltammetry and galvanostatic charge-discharge cycling. After a brief presentation about basic principles of operation and materials perspectives of Lithium Ion Batteries, typical results from one or two of our studies on both cathode and anode materials will be presented. A brief introduction to the Materials Research Society of Singapore (MRSS) and the International Union of Materials Research Societies (IUMRS) will also be given in order to highlight the ongoing and possible International Collaborative efforts.

Excitons and plasmons: A tale of two elementary excitations and their interaction

K. George Thomas

School of Chemistry, Indian Institute of Science Education and Research Thiruvananthapuram, Vithura,Thiruvananthapuram – 695551.

E-mail: kgt@iisertvm.ac.in Coupling of elementary excitations in the presence of light results in several newer optical phenomena.1 The coupling can be categorized as strong, weak and very weak, depending on the magnitude of the interaction. We have earlier demonstrated several examples of these interactions and its consequence on their optical properties.1 Our group has recently demonstrated examples of exciton-exciton coupling in molecules, and plasmon-plasmon coupling in plasmonic systems by organizing them in asymmetric fashion.2-4 As a consequence of such interactions, several fascinating chiroptical properties emerge.2-4 These aspects, along with our recent results on the generation of plexcitonic states5 will be presented in the first part of the talk. Precise assembly of plasmonic materials of desired size and shape allows further modulation of their optical and field effects, opening up several plasmonically powered processes such as surface enhanced spectroscopy.6-10 We have translated the principles of surface-enhanced spectroscopy for the design of plasmonic platforms, which can identify molecules of importance in health, environment and safety.9 These aspects will be discussed. 1.

Molecular design of Squaraines for photon based applications

Suresh Das

IISER- Thiruvananthapuram, Trivandrum sureshdas@iisertvm.ac.in

Squaraine dyes form a class of organic photoconducting materials, which along with other organic photoconductors, such as phthalocyanines, napthaquinones, cyanines, and azopigments, had originally received considerable attention for applications in xerographic photoreceptors and optical recording media. The D-A-D (donor-acceptor-donor) arrangement of squaraine dyes causes an interesting effect on the formation of intramolecular charge transfer states. As a result, the photophysical properties of these dyes are highly sensitive to the nature of the donor substituent groups and the environment. For example, the fluorescence yield of some squaraine dyes can be greatly enhanced by microencaging them in a polymer matrix or in cavities of β-cyclodextrin. The nature of the donor substituents in these dyes can be varied to yield a variety of symmetric and unsymmetrical dyes, resulting in significant impact on their absorption as well as photophysical properties. This tunability makes this class of dyes highly desirable for the design of materials for a variety of photon based applications. Our studies on the photophysical properties of some visible to near infrared absorbing squaraine dyes and their aggregates as well as on our studies related to their applications in solar cell, sensors and photobiology will be presented.

Excitements with group-IV semiconductor heterostructures for strain and bandgap engineered devices

Group-IV semiconductors and their heterostructures are very attractive for strain and bandgap engineered electronic and optoelectronic devices. Very exciting and promising results have been reported by us on strained group-IV alloy films (viz., SiGe, SiGeC, SiC, and strained-Ge on relaxed SiGe buffers), which paved the way of extending SiGe-based heterostructures, allowing additional flexibility in strain and bandgap engineering. On the other hand, Ge islands grown on Si (001) by molecular beam epitaxy (MBE) have been intensively examined as a model system for the formation of self-assembled quantum dots using strained-layer epitaxy. Our results on the characteristics of SiGe/Si quantum wells and self-assembled nano-sized Ge islands grown using solid source molecular beam epitaxy (MBE) will be presented. The ability to synthesize Si/Ge nanocrystals on oxidized Si substrates is an important development, which could be exploited to fabricate quantum dot field-effect transistor (FET) and flash memory devices. The light emission characteristics in the visible wavelength range from Ge nanocrystals embedded in different high band gap matrices, attributed to quantum confinement of carriers, will be presented. Embedded nanocrystals in high band gap oxide also acted as discrete trapping sites and were able to exchange charge carriers with the conduction channel by direct tunneling, the desired characteristics of floating gate memory devices. Finally, semiconductor nanowires and their heterojunctions have been demonstrated to be useful for nanophotonic applications. A review of our work on one-dimensional Si/Ge nanostructures for their possible applications in light emitting, charge storage, photodetector and photovoltaic devices will be presented.

School of Materials Sciences, Indian Association for the Cultivation of Science, Jadavpur, Kolkata 700032, India

Nanomaterials based light harvesting systems have been the subject of research because they are able to generate exciton after photoexcitation. Here, we focus on the understanding of the exciton dynamics, energy transfer, antenna effect, charge carrier dynamics, and other related processes of semiconducting

quantum dots (QDs), -conjugated semiconductor nanoparticles, and hybrid nanostructures.1-8 Ultrafast spectroscopic investigations provide direct insight into the impacts of electron and hole transfer at the interface in the hybrid materials for photocatalysis and photocurrent generation to construct efficient light harvesting systems. The fundamental knowledge of these photophysical processes is crucial for the development of efficient light harvesting systems. References 1. S. Kundu and A. Patra, Chem.

Nanomaterial synthesis: Our efforts towards bridging the "lab to market" gap

B. L. V. Prasad

Physical and Materials Chemistry Division National Chemical Laboratory (CSIR-NCL), Dr. HomiBhabha Road, Pune 411 008

e-mail: pl.bhagavatula@ncl.res.in Wet chemical approaches to nanomaterial synthesis provide great control over the sizes, shapes, and composition of nanoparticles. Here the control over size and shape is achieved by a better understanding of the reaction steps involved, the role of surface stabilizing agents, and reagents in the system as well as their correlations with growth and nucleation rate. However, to meet the industrial demands the synthesis procedure of any nanomaterial should be scalable without compromising the quality of the product. While typical chemical syntheses of nanomaterials are carried out in batch reactors problems such as batch-to-batch variations in size, shape, and composition when using the same procedure are big challenges being faced. An alternative approach to avoid batch-to-batch variation of Nanomaterials and to achieve high quality product with high throughput is to transform batch synthesis to flow synthesis and optimize the reaction parameters in a reproducible manner. In flow synthesis, smaller dimensions help to achieve rapid mixing and a higher interfacial area helps to enhance the mass transfer rates and high heat transfer rates throughout the reactor due to the high surface to volume ratio and the ability to reduce the extent of axial dispersion or back mixing. To transform any batch process into a continuous one, we need to understand the batch process thoroughly and optimize them. We have taken up this task and embarked on a journey to develop methods to synthesize nanomaterials in a continuous flow manner. For this we have selected few cases like metal, metal oxide nanoparticles and semiconducting metal sulphide nanocrystals. In each of these cases that we have carried out systematic studies to understand the batch processes thoroughly and later extended the same knowledge to develop/transform these processes into continuous flow methods. In this talk we will first briefly introduce the different approaches for the chemical synthesis of nanomaterials that are being practiced. We will then take up some case studies and delineate the challenges involved in developing continuous flow methods for the preparation of nanomaterials. Our efforts in successfully overcoming these challenges to yield reproducible and reliable size and shape selective synthesis of different classes of nanomaterials will be described. Apart from these recently we have reported an easy convenient method to access large quantities of a novel class of 2D layered materials, namely, metal thiolates. We also expanded the scope of utilization of these thiolate precursors for the preparation of metal/metal sulphide nanocrystals using mechano-chemical routes. Interestingly these metal nanocrystals could be easily dispersed in non-polar organic solvents though no solvent was used during their preparations. The results of these findings will be presented in the talk.

Email: kanishka@jncasr.ac.in With about 2/3 all utilized energy being lost as heat. Thermoelectric materials can convert waste heat to electrical energy and will significant role in future energy management. One of the fundamental challenges in developing high-performance thermoelectric materials has been to achieve low lattice thermal conductivity (κL). Nanoprecipitates of the size 1-20 nm embedded in bulk matrix are extraordinary to scatter the heat carrying acoustic phonon which decreases the κL and increases the thermoelectric figure of merit (zT) of 2.2 in PbTe.1Formation of layered intergrowth nanostructures in SnTe matrix or in the form of 2D heterostructure nanosheets by kinetic synthesis can also lead to ultralow κL.1,2 Nanodomains of 2D layered nanostructures such as in the case of SnSe are superior in decreasing thermal conductivity than that of the traditional spherical nanoprecipitates.3 Furthermore, the thermoelectric efficiency was experimentally measured to be ~12.3 % for the high performance nanostructured In and Bi co-doped GeTe based materials.4 Nanoprecipiates generally forms in the bulk matrix when enthalpy of the compound formation dominates over entropy of mixing in pseudo-binary systems such as PbTe-PbSe, SnTe-SnSe and GeTe-GeS. We have shown that entropy driven extended solid solutions in pseudo-ternary GeTe-GeSe-GeS system exhibited low κL and high thermoelectric figure of merit (zT) of 2.1.5 Intrinsic low thermal conductivity is of practical interest due to its robustness against grain size, temperature range and other structural variations. Recently, we have shown that the localized vibrations of Bi bilayer leading to ultralow lattice thermal conductivity and high thermoelectric performance in weak topological insulator n-type BiSe near room temperature.6 References

Recent studies on magnetic Heusler alloys

K. G. Suresh

Department of Physics, IIT Bombay, Mumbai

Heusler alloys have emerged as one of the most important topics in the field of applied magnetism in the recent past. These alloys are truly multifunctional and can be exploited for various applications. Martensitic alloys of this family are found to be promising for applications such as sensors, magnetic refrigeration etc. Another very important field of application of Heusler alloys is in spintronics. Combining the spin and charge of carriers is the key to spintronics. Spintronic materials can be classified into many groups, such as half metallic ferromagnets, spin gapless semiconductors, magnetic semiconductors etc.In addition to ferromagnets, antiferromagnets and ferrimagnets also attract a lot of interest in spintronics. All these categories have been found from the Heusler family. Several novel materials and novel phenomena have been discovered as a result of extensive experimental and theoretical investigations. In this talk, I will present some of the work that we have carried out in a variety of Heusleralloys in which the electronic band structure is systematically tuned to synthesize novel and better materials. The talk will also cover some of the very novel aspects that have come out of the extensive studies carried out on different classes of materials.

Exploring Air-Water Interface for Highly Luminescent Molecular Assemblies

Somobrata Acharya

School of Applied & Interdisciplinary Sciences, Indian Association for the Cultivation of Science, Jadavpur, Kolkata-700 032 Email: camsa2@iacs.res.in

Recently, aggregation induced emission (AIE) phenomena have drawn a great interest owing to the strong luminescence realized in aggregated state. AIE effect adds a new dimension to the optoelectronic technologies, where luminophores are used in solid state for device fabrication. We explore for the first time controlled supramolecular assemblies of AIE active complexes within Langmuir monolayer with the aid of surface pressure. Owing to the confined geometry within the supramolecular assembly, restriction of intramolecular vibration and rotations of the ligands occur which facilitate strong AIE effect (1, 2). As a consequence, a large enhancement of luminescence comparable to the solid state is obtained from the supramolecular aggregates, even from a monolayer. In order to understand the inherent mechanism of high luminescence, we performed in-situ Grazing Incidence X-Ray Diffraction (GID) at the air-water interface with varying surface pressure, which enable us to reveal the critical structural organization that leads to high luminescence. The origin of AIE effect is further explored from the unit cell obtained from the GID measurements by using density functional theory (DFT) calculations. The unique aggregation feature is utilized for the fabrication of light emitting diodes with low threshold voltage using supramolecular assemblies as active layer. References 1. Subrata Maji, P.

Environmental pollution has become a pressing global challenge owing to the direct influence it has on the quality of human life and its detrimental impact on the ecological balance. Pollution control agencies across the world have identified certain species as priority pollutants and called for methods/materials to respond to this growing challenge. Metal-organic frameworks (MOFs) have emerged as a prominent class of porous materials which can function as sensors and/or adsorbents for a wide range of target species.1,2 The applicability of luminescent MOFs for sensing and sequestration of toxic pollutants such as cyanide (CN-), Hg2+ ions etc will be presented (Fig. 1). Also, the utility of ionic-MOFs (iMOFs) as ion-exchange adsorbents for the capture of noxious heavy-metal oxo-anionic pollutants will be discussed.3-4

Light-matter coupling and charge transfer dynamics in monolayer MoS2 and WS2 based Van der Walls heterostructures

P. K. Giri*

Department of Physics and Centre for Nanotechnology, I.I.T. Guwahati, Guwahati 781039 *Email: giri@iitg.ac.in

Two-dimensional atomic crystals of graphene, as well as transition-metal dichalcogenides, have emerged as a class of materials that demonstrate strong interaction with light. Tuning the optoelectronic properties of 2D semiconducting materials is of paramount importance for their ensuing applications in next generation optoelectronics and photonics. An effective and convenient method to tune the optical properties of monolayer MoS2 (1L-MoS2) and WS2 is to control their charge density by heterostructure approach. In the 1st part of the talk, I will discuss about the charge transfer and associated doping of 1L-MoS2 (see Fig. 1(a-c)) through its decoration of WS2 quantum dots (QDs). We investigate the mechanism of photoluminescence (PL) quenching in monolayer MoS2 (1L-MoS2) after its decoration with WS2 QDs. The direct band gap 1L-MoS2 and monolayer WS2 QDs are grown by chemical vapour deposition and liquid exfoliation methods, respectively. A quantitative analysis of the evolution of the PL spectra of the 1L-MoS2 /WS2 QD heterostructure as a function of concentration of WS2 QDs reveals coupled charge transfer from the WS2 QDs to different electronic levels of 1L-MoS2. A detailed quantitative analysis using the four-energy level model (see Fig. 1(d)) was employed to explain the red shift and the decrease in the intensity of the PL peak in 1L-MoS2/WS2 QD heterostructure. Our study reveals the contribution of defects in the coupled charge transfer dynamics in 1L-MoS2 and it lays out a convenient strategy to manipulate the optical and electrical properties of 1L-MoS2 for various optoelectronic applications. Next, I will discuss about the strong light-matter interaction and enhancement of PL emission (about three orders of magnitude) from 1L-MoS2 by direct CVD growth on a fluorine doped TiO2 substrate and further embedding a plasmonic metal (Ag, Au) nanoparticles layer below the 1L-MoS2 layer. The enhancement is attributed, firstly, to heavy p-doping of the MoS2 lattice, caused by the migration of the excess electrons from the MoS2 to TiO2 side and leading to conversion of trions to neutral excitons. Secondly, to the localized surface plasmons, which enhance the PL emission of TiO2/Au/MoS2 and TiO2/Ag/MoS2 heterostructures using sputter deposited Au/Ag nanoparticles. Finally, the applications of these heterostructures as efficient broadband photodetectors with ultrafast response will be presented.

Li-ion batteries (LIB) are continuous to conquer the niche market and anticipated extensively to power the zero emission transportations like plug-in hybrid electric vehicles (P-HEV) and electric vehicles (EV). Development of High energy and high power densities are desperately warranted to power such as P-HEV and EV applications. There are two ways to increase the energy density, the first approach is the utilization of high voltage cathodes (>4.5 V vs. Li), or employing high capacity anodes (> 600 mAh g–1) with lower working potential (< 0.3 V vs. Li) or the combination of those two approaches. My presentation mainly emphasizes the research progress and challenges for the development of high voltage cathodes like LiCoPO4 and LiNi0.5Mn1.5O4. Further, the demonstration of rocking-chair type LIB with graphite and anatase type TiO2 anodes with aforesaid cathodes will be highlighted. In addition, the possibility of using conversion (Fe based oxides) and alloy (SnO2) type materials in practical assemblies will be discussed with spinel cathodes. Finally, the necessity for R & D on spent battery re-cycling will be underlined. References 1. V. Aravindan* and Y.S. Lee, J. Phys. Chem. Lett. 9 (2018) 3946 2. V. Aravindan*, and Y.S. Lee, Adv.

Do we understand optical transitions in 2D hybrid perovskites?

In 1990s, David Mitzi and coworkers proposed a quantum well structure for layered hybrid perovskites like (BA)2PbI4 (BA = C4H9NH3). In this model, electron and hole are confined in atomically thin (< 1 nm thickness) Pb-I inorganic well layers, separated by the insulating organic barrier layers. Therefore, these layered perovskites are considered as electronically 2D systems, irrespective of their crystallite sizes. More than two decades later, theoretical studies are still debating over this model. Not far behind is our puzzling experimental observation that suggest single crystal of (BA)2PbI4 has dual optical band gap! In this talk, I would like to discuss some unusual facts about the band gap of 2D hybrid perovskites, and verify whether the electronic dimensionality is really 2D or not. One of our tricks is to reversibly change the distance between the inorganic wells, and therefore changing the electronic interactions between them, by intercalating different organic and inorganic molecules into single crystals of 2D hybrid perovskites. Interestingly, the intercalation can reversibly switch the two excitonic emissions (dual band gap) to a single excitonic emission (single band gap). Does it suggest that the so-called isolated Pb-I inorganic wells actually interact with each other? Well, the story is not so simple, and there are roles of (i) edge states and (ii) dielectric confinement in complicating optical band gap. All these discussion are crucial not only for optical properties of single crystals, but also for charge transport and charge transfer in an optoelectronic device based on 2D hybrid perovskites.

Functional metal oxide hybrid nanostructures combine the favourable properties of the constituent materials for achieving multifunctionality. Functional metal oxide nanostructures and nano-hybrids have attracted significant attention for diverse applications, i.e. energy storage, mechanical energy harvesting, chemical sensing and other applications. The present talk is concerned with the engineering of the properties of the functional metal oxide nanostructures and nanocomposite prepared by the facile wet chemical method, hydrothermal and thermal decomposition method for supercapacitor, nanogenerators, gas sensing, and room temperature magnetic applications. With the development of the modern economy, faster and higher energy storage systems are essential for several applications. Supercapacitors are the best candidates for providing the necessary high power and long durability needed for new energy devices for uninterrupted power supply. WOx, MnO2, Co3O4 nanostructures are identified as promising materials for energy storage purposes [1-3]. Further, rGO-Ag/PVDF nanocomposite was used to realize a mechanical energy harvesting device that could light LEDs, charge capacitors and harvest bio-mechanical energy [4].The ability to monitor indoor air quality is realized by studying the gas and humidity sensing properties of Sr- and Ni- doped ZnO nanostructures. The as fabricated chemical sensors showed good sensitivity, selectivity and stability towards H2O, CO, CO2, etc. [5, 6]. The size and shape-controlled CoFe2O4 nanoparticles were explored for room temperature magnetic applications. The excellent magnetic properties indicated the capabilities of CoFe2O4 NPs in permanent magnets for current technological applications [7].

Transformation of molecular photoredox complexes to heterogeneous forms for highly efficient conversion of carbon dioxide to chemicals

Suman L. Jain

Chemical & Material Sciences Division CSIR-Indian Institute of Petroleum, Dehradun-248005

suman@iip.res.in Photochemical reduction of CO2 using solar energy is an area of tremendous importance as it can tackle both the issues of the global warming and shortage of the fossil resources.1 The transformation of CO2 into chemicals and fuel by using solar light irradiation is an effective method because there is no addition of extra energy and no negative influence on the environment. The immediate requirement in this technology is to develop visible light-sensitive photocatalysts, which are prominent in CO2 recycling. So far a number of photocatalysts mainly semiconductors based have been introduced by many researchers, however their quantum yields and selectivities of products are low.2 Transition-metal complexes such as ruthenium(II) polypyridine carbonyl complex, cobalt(II) trisbipyridine, and cobalt(III) macrocycles with or without a photosensitizer have also often been used as photoredox catalysts for CO2 conversion.3 These catalysts are advantageous over semiconductor systems as they can absorb a significant portion of the solar spectrum, have long-lived excited states, can promote multi-electron transfer and activate small molecules through binding. The large availability and tunable properties of transition metal complexes make them a favorite choice as sensitizers, with the added possibility of using polymeric ligands for more organized systems. So far the rhenium-(I) bipyridine (bpy) complexes i.e. fac-[ReI(bpy)(CO)3(L)]n+(L )Cl (n) 0); PR3 (n ) have been considered to be most effective and high yielding photocatalysts, which can work not only as a catalyst but also as a photosensitizer, and CO is the principal product of CO2 reduction.4 However, the presence of organic ligands raises concerns about long term stability of the catalyst. In addition difficult recovery and non-recycling ability of such catalysts make their applicability limited from industrial viewpoints. One of the logical approaches to overcome these limitations is to immobilize such metal based photoredox catalysts to photoactive supports like TiO2, graphene oxide etc. The covalent attachment of these complexes to the photoactive supports not only enhances the stability of these complexes however, make their recovery and reusability feasible. During our recent research we have designed and developed a number of highly effective hybrid photocatalysts by combining molecular photoredox complexes to photoactive supports for the significantly improved conversion of CO2 to high value chemicals such as methanol, carbonates and carboxylic acids.5-7 References 1.
