Droughts boost emissions as hydropower dries up

When hydropower runs low in a drought, western states tend to ramp up power generation—and emissions—from fossil fuels. According to a new study from Stanford University, droughts caused about 10 percent of the average ...

New device for symmetry-breaking-induced optical nonlinearity

Second-order nonlinear optical processes play a pivotal role in both classical and quantum applications, ranging from extension of the accessible frequencies to generation of quantum entangled photon pairs and squeezed states. ...

Treated superalloys demonstrate unprecedented heat resistance

Researchers at Idaho National Laboratory have discovered how to make "superalloys" even more super, extending useful life by thousands of hours. The discovery could improve materials performance for electrical generators ...

Making steps toward improved data storage

A team of scientists has created the world's most powerful electromagnetic pulses in the terahertz range to control in fine detail how a data-storage material switches physical form. This discovery could contribute to scaled-down ...

New material cleans and splits water

Metal-organic frameworks (MOFs) are among the most useful and versatile materials today, demonstrating structural versatility, high porosity, and fascinating optical and electronic properties. These characteristics make them ...
