A four-way switch promises greater tunability of layered materials

A scientific team from the Department of Energy's Oak Ridge National Laboratory and Vanderbilt University has made the first experimental observation of a material phase that had been predicted but never seen. The newly discovered ...

Protein imaging at the speed of life

To study the swiftness of biology—the protein chemistry behind every life function—scientists need to see molecules changing and interacting in unimaginably rapid time increments—trillionths of a second or shorter.

Foam offers way to manipulate light

There is more to foam than meets the eye. Literally. A study by Princeton scientists has shown that a type of foam long studied by scientists is able to block particular wavelengths of light, a coveted property for next-generation ...

Hot electrons harvested without tricks

Semiconductors convert energy from photons (light) into an electron current. However, some photons carry too much energy for the material to absorb. These photons produce "hot electrons," and the excess energy of these electrons ...

Discovery of a new type of particle beam instability

Accelerated, charged particle beams do what light does for microscopes: illuminate matter. The more intense the beams, the more easily scientists can examine the object they are looking at. But intensity comes with a cost: ...
