As demand for hydrogen-energy technologies grows, so does the need for iridium, a precious metal so scarce that only about eight tons are produced worldwide each year. University of Delaware researchers have developed a green recycling process that recovers iridium, platinum and the membranes used in hydrogen electrolyzers and fuel cells without relying on harsh chemicals or high-temperature burning. The work could help address a critical supply-chain challenge while reducing waste from clean-energy technologies. The technology is now being advanced toward commercialization through University of Delaware's Office of Economic Innovations and Partnerships.

Researchers have developed a sulfur host with asymmetric Zn-N4-S single atom sites that improves the performance of the aqueous zinc–sulfur batteries with nearly theoretical value and record-low polarization. They propose to overcome sluggish solid-solid conversion kinetics using coordination microenvironment engineering.
Images of faces created by Artificial Intelligence (AI) are seen as more trustworthy than images of genuine faces say researchers, who warn of the risks of online fraud and other harms.
This is the first ever study to examine the trustworthiness of AI faces created by the latest diffusion technology and was led by Lancaster University with Stanford University and the University of California, Berkeley.
Lead researcher Lex McGuire said: “As AI-generated images become more sophisticated and more accessible, as a society, we are increasingly exposed to artificially-generated faces—often in nefarious and exploitative scenarios, such as political disinformation, financial and identity fraud, and catfishing.”
