Athina Anastasaki joined ETH Zurich in 2019. Her research focuses on the next generation of polymers and recycling processes for these. She wants to recover all the starting materials and use them to produce new materials for other applications.

EPFL scientists have made an important discovery about the structure of barium titanate, a material used in everyday objects. Their findings refute existing theories on the displacement of the material’s atoms. 

The number of data-transmitting microdevices, for instance in packaging and transport logistics, will increase sharply in the coming years. All these devices need energy, but the amount of batteries would have a major impact on the environment. Empa researchers have developed a biodegradable mini-capacitor that can solve the problem. It consists of carbon, cellulose, glycerin and table salt. And it works reliably.

Physical chemists and chemical engineers led by EPFL have used a chemical tweak to push the power-conversion efficiency and operational stability of perovskite solar cells to 25.6% and at least 450 hours respectively.
