Organic particles modulate soot mixing in the atmosphere

In the atmosphere, individual soot particles emitted from human activities often encounter and combine with organic material, forming soot-containing particles. A research team led by scientists from the U.S. Department of ...

Swimming bacteria work together to go with the flow

Swimming bacteria can reduce the viscosity of ordinary liquids like water and make them flow more easily, sometimes down to the point where the viscosity becomes zero: the flow is then frictionless.

Unusual thermal convection in a well-mixed fluid

Researchers from Tokyo Metropolitan University, have recently discovered unusual thermal convection in a uniform mixture of high- and low-viscosity liquids. Kobayashi and Kurita found that concentration fluctuations are enhanced ...

Bacteria change a liquid's properties and escape entrapment

A flexible tail allows swimming bacteria to thin the surrounding liquid and to free themselves when trapped along walls or obstacles. This finding could influence how bacterial growth on medical, industrial, and agricultural ...

Thinning out the carbon capture viscosity problem

To make "clean" fossil fuel burning a reality, researchers have to pull carbon dioxide out of the exhaust gases that rise from coal or natural gas power plants and store or reuse it. For the capturing feat, researchers are ...
