New scheme for creating a stable artificial photosynthesis device

Materials Today: A research team has developed a new artificial photosynthesis device with remarkable stability and longevity for converting sunlight and carbon dioxide into two promising sources of renewable fuels – ethylene and hydrogen. In a paper on this work in…

Melted MOF makes perovskites shine

C&EN: Researchers have melted metal-organic frameworks (MOFs) and mixed them with perovskites to yield highly stable luminescent composites (Science 2021, DOI: 10.1126/science.abf4460). The mixtures resist exposure to heat, air, and humidity, expanding the g possibilities for light-emitting devices. Lead-halide perovskites, such as cesium lead iodide, naturally exhibit photoluminescence, says…

C&EN’s 2021 10 Start-Ups to Watch

C&EN: Just 10 days ago in Glasgow, Scotland, political leaders from around the world wrapped up a United Nations climate conference intended to chart a course toward a low-carbon future. The goal: saving Earth from carbon dioxide–driven destruction. Critics say…

New Technique Generates 3D Images of Bacteria for Antibiotic Susceptibility Testing

Medgadget: Researchers at the University of Connecticut have developed a highly sensitive imaging sensor that can rapidly and accurately monitor bacterial growth. The technique involves shining laser light through…
