For the first time, researchers have discovered a way to obtain polarity and photovoltaic behavior from certain nonphotovoltaic, atomically flat (2D) materials. The key lies in the special way in which the materials are arranged.

Cavitation has been widely assumed to be the underlying mechanism governing the fracture of metallic glasses, as well as other glassy systems. Up until now, however, scientists have been unable to directly observe the cavitation behavior of fractures, despite their intensive efforts.

The typical 'top-down' method of producing carbon nanotubes does not allow for control over their diameter, length or which of three types will be produced. Control over two types has recently been demonstrated by producing their elementary 'nanobelt' molecules, and now researchers have developed a way to construct the third and last type, offering complete 'made-to-order' management of the synthesis of nanotube molecules.

Scientists report that, when driven out of equilibrium by magnetic fields, a universal Doppler effect limits the maximal spin current in magnetic insulators. This finding is a surprising analogy to what happens in superconductors driven by electric fields and could provide a fundamental design principle for future nano-devices with computing science and power applications.
