Researchers in Sweden and the US say that chemically recycling perovskite solar cells could cut their costs, making them more competitive with the leading technology – crystalline silicon modules. Feng Gao’s team at Linköping University, Sweden, has developed a technique to cheaply and repeatedly take apart solar cells made of perovskite materials and make new high-performance devices. The conditions they use are environmentally friendly, primarily water based.

Eyeing the bruises on the knuckles of the police officer arresting me, I took a deep breath and explained why we need to act faster to avoid climate catastrophe. Standing on a traffic island in London, I looked straight into his body-worn video camera, and hoped the speech would make it to the courtroom.

Shawn Kefauver a vu de ses yeux vu des compagnies pétrolières faire des “trucs louches” en Équateur. Mais le seul témoignage retenu par la justice a été celui de l’analyse des données enregistrées depuis l’espace à laquelle il a contribué. Pas le sien. Avec ses collègues, ce chercheur de l’université de Barcelone a eu l’idée d’utiliser le spectre lumineux enregistré par les satellites pour suivre les changements de la forêt amazonienne à proximité des installations pétrolières équatoriennes.

Andy Extance charts how research into revolutionary targeted protein degradation therapies is moving from serendipity to strategic discovery One of today’s hottest pharmaceutical research areas owes much to alphabetically ordered posters at the 1999 annual Burroughs Wellcome Fund (BWF) scholars’ retreat. Though they both had received a BWF Junior Faculty Award, Craig Crews and Ray Deshaies hadn’t discussed their work before.

Chemists in China and the US have discovered catalysts enabling light-driven reactions that can break down fluorine-containing chemicals that are attracting concern as pollutants. Two research groups separately harnessed a powerful new class of carbon-based catalysts that help break bonds between carbon and fluorine atoms, avoiding using and producing other harmful chemicals.

Easy to make and versatile enough to go on everyday devices, perovskite solar cells are hampered by poor stability and lead toxicity. It should be possible to cheaply and cleanly recycle them, which enhances their chances of commercial success. By me: https://t.co/oj6roncYqo
I was today years old when I discovered pure calcium metal can be a bit yellowy. I have seen a photo that looks yellow and is apparently 99.999% pure but is copyrighted so I can't share it. Most online photos of calcium don't look yellow. Anyone know the scientific reason why?
