How to replace PFAS?

PFAS substitution in medical technology

05-Nov-2024 - Hardly any other chemical substance can compete with PFAS, due to their unique properties. That explains why it is so hard to find a replacement for these toxic “forever chemicals”, which accumulate in the environment and do not break down over time. A team at the Fraunhofer Institute for ...

Environmentally friendly non-stick coating replaces per- and polyfluorinated chemicals (PFAS) on everyday products

16-Oct-2023 - Whether it is pans, cutlery or packaging, per- and polyfluorinated chemicals (PFAS) have been used for coating in a wide variety of everyday products and processes for many years. Due to known risks of these substances to humans and the environment, at least a partial ban on the production and ...

New concept for lithium-air batteries

Research project in Germany aims to improve the stability of this novel battery type

09-May-2023 - Lithium-air batteries, also known as lithium-oxygen batteries, are candidates for the next generation of high-energy electricity storage devices. Their theoretical energy storage capacity is ten times that of conventional lithium-ion batteries of the same weight, but they are not yet chemically ...

With new measurement methods for a longer service life of battery cells

More sustainability in electromobility and Co

14-Mar-2023 - The aging of battery cells cannot be easily determined under real conditions. However, an accurate statement about the aging state of the cells in operation forms the basis for a better understanding of the aging mechanisms of a battery and for extending its lifetime. In order to be able to ...
