Slimy, hard-to-clean bacterial mats called biofilms cause problems ranging from medical infections to clogged drains and fouled industrial equipment. Now, researchers at Princeton have found a way to cleanly and completely peel off these notorious sludges.
Popping the top on house paint usually draws people to look inside the can. But Princeton researchers have turned their gaze upward, to the underside of the lid, where it turns out that pattern of droplets could inspire new ways to make microscopically small structures.
Using nearly undetectable particles, a team of international researchers has peered into the sun’s heart and sketched the intricate chain of reactions that drive the solar furnace.
In a paper published June 30 in Nature Energy, Yueh-Lin (Lynn) Loo and her co-workers describe how they used organic semiconductors for constructing solar cells that are transparent but can be tinted to block 80% of the light under their own power.
In a paper published June 26, 2017 in Nature Chemistry, Clifford P. Brangwynne and his co-workers have described the formation of liquid droplets forming inside living cells.
