An anode-free zinc battery that could someday store renewable energy
20 Jan 2021 at 5:50am
Renewable energy sources, such as wind and solar power, could help decrease the world's reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials.
Advanced light reveals how different biofuels behave

Discovery of chromophores that emit light in the ultraviolet region when exci...
18 Dec 2020 at 8:24am
Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When excited by visible light, the fluorescent dyes emit light in the ultraviolet region. According to the study, such light upconversion systems could boost the light-dependent reactions for which efficiency is important, such as solar-powered water splitting.
