Stable solar cells from perovskite
14/10/2021 - Perovskite is a promising material. It captures the sun's rays and efficiently converts them into solar energy. It is also much cheaper than the current generation of silicon solar cells. But why are...
Molecular mixing creates super stable glass
14/10/2021 - Researchers at Chalmers University of Technology, Sweden, have succeeded in creating a new type of super-stable, durable glass with potential applications ranging from medicines, advanced digital...
Researchers engineer hardier microbes to improve bioproduction of fuels, chemicals
13/10/2021 - Busy, productive microbes use enzymes to break down leaves, stalks and other biomass and then convert that material into renewable fuels and chemicals. But some of those enzymes can't function at the...
A strategy to manipulate photocurrent direction in p-n heterojunction nanowires
12/10/2021 - Semiconductor p-n junctions are boundaries between two types of semiconductors (i.e., p-type and n-type semiconductor materials). These junctions are crucial components of many modern electronic...
Resurrecting quasicrystals: Findings make an exotic material commercially viable
11/10/2021 - A class of materials that once looked as if it might revolutionize everything from solar cells to frying pans—but fell out of favor in the early 2000s—could be poised for commercial resurrection,...
