Ultrasound will help fight against “eternal chemicals”.

Scientists from the University of Lester developed a new ultrasound technology that allows you to effectively distinguish materials in fuel elements for later processing. This is an important step to reduce the environmental effects of PFAS fluorine compounds known as “eternal chemicals .. Published in İş Magazine RSC Sustainability.

PFAs are widely used in fuel elements and hydrogen electrolyzers – the basic components of hydrogen energy used in cars and trains. However, a powerful clutch between precious metals (such as platinum) and PFAS membranes made it difficult to process these devices. The new technique that allows you to get wet in an organic solvent and to separate these components safely and effectively.

Dr. Lester University Chemical School Dr. “We were able to separate PFAS membranes from precious metals without using aggressive chemicals, Jake Jake Yang said. “This makes the process simpler and more scalable and brings us closer to a closed cycle of the use of rare metals necessary for the development of pure energy.”

In the continuation of the project, the researchers brought a continuous business process using an ultrasound knife – an ultrasound knife that caused small bubbles in the fluid. These bubbles collapse under pressure, instantly separating the layers of membranes and catalysts at room temperature. It turned out that the process was not only fast, but also economically effective.

The study was carried out jointly with world leader Johnson Matthey in sustainable technologies. According to the leading researcher in Ross Gordon, the use of high -into -intended ultrasound “changes the rules of the game” in the processing of fuel elements and makes hydrogen energy more appropriate and environmentally friendly.
