Flexible, semi-transparent ultrathin solar cells

A lot of research has been done on graphene recently—carbon flakes, consisting of only one layer of atoms. As it turns out, there are other materials too which exhibit remarkable properties if they are arranged in a single ...

Scientists discover chiral phonons in a 2-D semiconductor crystal

A research team from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally ...

Surprising new health and environmental concerns about tungsten

Surprising new scientific research is raising concerns about the potential health and environmental hazards of tungsten — a metal used in products ranging from bullets to light bulbs to jewelry — that scientists once ...

Tracking conflict minerals in Congo

Eastern Congo's hillsides are rich in an element that most people have never heard of, a metal that is inside most of the mobile phones, laptops, and other electronics that we use every day.

Researchers simulate helium bubble behavior in fusion reactors

One of the most important challenges for successful commercialization of fusion power is the development of materials that can tolerate the extreme conditions of elevated temperatures and high particle flux of hydrogen isotopes ...
