Keeping cool with quantum wells

University of Tokyo researchers have announced a new approach for electrical cooling without the need for moving parts. By applying a bias voltage to quantum wells made of the semiconductor aluminum gallium arsenide, electrons ...

Smart mud to smooth the way for drilling wells

A model that simulates how drilling fluids, or muds, behave and influence the stability of oil wells has been developed by KAUST researchers. Their findings could inform new safety protocols and the design of novel drilling ...

Making a better nitrate test kit

The dull black plastic of the device on Joshua Pearce's desk belies its usefulness. Pearce picks up the box, which has a switch on the side and a small opening on top. A handful of vials sit in a bag nearby, and each would ...

Groundwater is safe in potential N.Y. fracking area

Two Cornell hydrologists have completed a thorough groundwater examination of drinking water in a potential hydraulic fracturing area in New York's Southern Tier. They determined that drinking water in potable wells near ...

Stray gases found in water wells near shale gas sites

Homeowners living within one kilometer of shale gas wells appear to be at higher risk of having their drinking water contaminated by stray gases, according to a new Duke University-led study.
