In the switch to 'greener' energy sources, the demand for rechargeable lithium-ion batteries is surging. However, their cathodes typically contain cobalt -- a metal whose extraction has high environmental and societal costs. Now, researchers in report evaluating an earth-abundant, carbon-based cathode material that could replace cobalt and other scarce and toxic metals without sacrificing lithium-ion battery performance.

Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical? In a new study, researchers describe a potential COVID-19 test inspired by bioluminescence. Using a molecule found in crustaceans, they have developed a rapid approach that detects SARS-CoV-2 protein comparably to one used in vaccine research.

Researchers use light-reactive molecules to influence the acidity of a liquid and thereby capture of carbon dioxide. They have developed a special mixture of different solvents to ensure that the light-reactive molecules remain stable over a long period of time. Conventional carbon capture technologies are driven by temperature or pressure differences and require a lot of energy. This is no longer necessary with the new light-based process.
