sirris materials day 2011 can you read the materials future - umberto baraldi-sirris

Welcome to the plenary session !

A serious day starts with a serious question !

Can you read the materials futurein a Polystyrene crystal ball ?


Drivers and consequences !

Main drivers• Availability

• Limited distant resources• Large scale production limits

• Renewability• Natural renewable sources• Recycling

• Ecological impact / cost• Producing• Transforming• Using

Drivers and consequences !

Consequences• Performance

• Hi performance processes• Uncommon/new performances• Higher merit factor

• Functionality• Multifunctionality• Focussed performance

• Renewable sources• Bio-sourcing• Recycling




Can you read the materials future in a Polystyrene crystal ball ?

Availability



Availability



Hi Performance processes : Microreactors

Microfluidic devices

Diagnosticschips,

lab-on-chip

MicroreactorTechnology

(MRT)

MicrochannelHeat Exchangers

Synthesis, Pharma

Medical,Biotech

Thermalmanagement



Hi Performance processes : Microreactors

• Constant quality,

• Reaction time and parameter control

• Energy efficiency and ressources

• Very small Reacting volume, new type of batch chemistry allowed

formerly forbidden for security and toxicity reasons

• Process industrialisation by adding-up and not scaling-up



Higher Merit Factor : Less for the same purpose



Renewable Resources : Bio- sourcing



Uncommon properties : Nanomaterials

• Why go Nano ?

• Small is beautifull ?

• Size Matters!!!!




Lots of Physical phenomena have keydimensions in the range of Nanomaterials !




nano scale propertiesdiffer from macroscale !

- More particles per volume- More atoms at the surface- More atoms at grain

interfaces- More grain interfaces- Quantum physics take

lead!

In nanomaterials, atomsinteracting with the externalworld are 1000 X more numerous!Nano = Taste enhancers !
