Speeding innovation for industry
Materials and processes
Nanomaterials are crucial to giving materials the specific properties required for certain applications. These properties can include lower melting temperatures and a higher surface-to-volume ratio, useful in catalysis. CEA Tech institute Liten is developing nanomaterials synthesis processes employing the most “nano-safe” approach possible. This entails using liquid-phase synthesis reactors and reactors equipped with confinement systems if gaseous-phase processes cannot be avoided. Insofar as possible, the various steps in the synthesis process are carried out without removing the material from the confined environment.
For example, Liten researchers have successfully grown very dense carbon-nanotube carpets from a substrate. The carbon nanotubes, which offer excellent electrical conductivity, are woven into thread that could ultimately be used to make electrical wire to replace today’s copper wire.
In research conducted for the EU INTEGRAL project, Liten, a CEA Tech institute, helped scale up second-generation thermoelectric materials and validation-test their use on functional thermoelectric generator demonstrators.
Resistive memory with revolutionary properties is made possible by a phenomenon known as ovonic threshold switching, or OTS. Researchers at Leti, a CEA Tech institute, recently shed new light on the topic.
Reliable and reproducible nanomaterials characterization protocols have been developed at Liten and are now available to businesses for their nanomaterials testing campaigns.
Liten, a CEA Tech institute, recently patented the world’s first 100% polymer film that is both conductive and transparent. The new film could be a good candidate to replace existing materials in electrodes and transparent heating films.
For the first time ever, scientists at Liten used XPS to observe changes in the chemical composition of lithium-ion batteries during operation. The purpose of the research was to gain a deeper understanding of battery degradation mechanisms.
How to collaborate with CEA Tech teams ?
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
