Tiny particles that seed clouds can form from trace gases over open sea — ScienceDaily

New results from an atmospheric study over the Eastern North Atlantic reveal that tiny aerosol particles that seed the formation of clouds can form out of next to nothingness over the open ocean. This “new particle formation” occurs when sunlight reacts with molecules of trace gases in the marine boundary layer, the atmosphere within about […]
Tiny particles that seed clouds can form from trace gases over open sea

Results from a study of clouds and aerosols conducted in the Azores revealed that new particles can seed the formation of clouds in the marine boundary layer—the atmosphere up to about a kilometer above Earth’s surface—even over the open ocean, where the concentration of precursor gases was expected to be low.

Graphene balloons to identify noble gases

Credit: TU Delft/Makars Šiškins New research by scientists from Delft University of Technology and the University of Duisburg-Essen uses the motion of atomically thin graphene to identify noble gasses. These gasses are chemically passive and do not react with other materials, which makes it challenging to detect them. The findings are reported in the journal […]
Electrically switchable system could continuously separate gases without the need for moving parts or wasted space — ScienceDaily

A new system developed by chemical engineers at MIT could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively […]
Researchers discover that bacteria that ripen cheese respond to the volatile gases produced by cheese fungi — ScienceDaily

Researchers at Tufts University have found that those distinctly funky smells from cheese are one way that fungi communicate with bacteria, and what they are saying has a lot to do with the delicious variety of flavors that cheese has to offer. The research team found that common bacteria essential to ripening cheese can sense […]
