Increasing tree mortality in a warming world

A mix of factors is contributing to an increasing mortality rate of trees in the moist tropics, where trees in some areas are dying at about twice the rate that they were 35 years ago, according to a far-reaching study examining ...

Corralling xenon gas out of waste streams

From space propulsion to lighting to surgical anesthesia, the applications and needs for xenon gas are growing. And the good news is that researchers are advancing the science to more easily remove xenon from waste streams ...

Measuring small forces that lead to large effects

Forces between individual particles in slurries are responsible for their rheological behavior. Direct quantification of physical forces between mineral faces is now possible with atomic force microscopy, thanks to work at ...

Mastering tailored design of aluminum nanomaterials

Whether for energy applications or nuclear waste management, industrial processing of aluminum requires understanding its behavior in highly alkaline solutions. Processing slurries and precipitates (typically gibbsite, α-Al(OH)3) ...
