Computer model identifies candidate refrigerants to combat global warming

September 19, 2012 5:26 am | News | Comments

Researchers at NIST have developed a new computational method for identifying candidate refrigerant fluids with low global warming potential—the tendency to trap heat in the atmosphere for many decades—as well as other desirable performance and safety features. The NIST effort is the most extensive systematic search for a new class of refrigerants that meet the latest concerns about climate change.

Study estimates increasing rate of extreme rainfall with global warming

September 17, 2012 10:03 am | by Jennifer Chu, MIT News Office | News | Comments

Global warming is expected to intensify extreme precipitation, but the rate at which it does so in the tropics has remained unclear. Now, a new study has given an estimate based on model simulations and observations: With every 1 C rise in temperature, the study finds, tropical regions will see 10% heavier rainfall extremes, with possible impacts for flooding in populous regions.

New nanoparticle system finds mercury in water, fish

September 13, 2012 4:33 am | by Erin White | News | Comments

The system currently being used to test for mercury and its very toxic derivative, methyl mercury, is time-intensive, costly, and can only detect quantities at already toxic levels. Researchers at Northwestern University and in Switzerland have invented a device consisting of a strip of glass with a nanoparticle film attached that can detect heavy metals in quantities more than a million times smaller than is currently possible.

Nano-velcro clasps heavy metal molecules in its grips

September 10, 2012 5:31 am | News | Comments

Mercury, when dumped in lakes and rivers, accumulates in fish, and often ends up on our plates. A Swiss-American team of researchers has devised a simple, inexpensive system based on nanoparticles, a kind of nano-velcro, to detect and trap this toxic pollutant as well as others. The particles are covered with tiny hairs that can grab onto toxic heavy metals such as mercury and cadmium.
