Superradiance quantum effect detected in tiny diamonds
Under certain conditions, an atom can cause other atoms to emit a flash of light. At TU Wien (Vienna), this quantum effect has now been measured.

Autocannibalistic materials feed on themselves to grow new nanostructures
Scientists at the Department of Energy's Oak Ridge National Laboratory induced a two-dimensional material to cannibalize itself for atomic "building blocks" from which stable structures formed.
Schwarzites: Long-sought carbon structure joins graphene, fullerene family
The discovery of buckyballs surprised and delighted chemists in the 1980s, nanotubes jazzed physicists in the 1990s, and graphene charged up materials scientists in the 2000s, but one nanoscale carbon structure—a negatively ...
In a first, scientists precisely measure how synthetic diamonds grow
Natural diamond is forged by tremendous pressures and temperatures deep underground. But synthetic diamond can be grown by nucleation, where tiny bits of diamond "seed" the growth of bigger diamond crystals. The same thing ...
Silver salt used to break C–C bonds in unstrained cyclic amines
A team of researchers at the University of California has found a way to break C–C bonds in unstrained cyclic amines using silver salt. In their paper published in the journal Science, the group describes the technique ...
Manipulating single atoms with an electron beam
All matter is composed of atoms, which are too small to see without powerful modern instruments including electron microscopes. The same electrons that form images of atomic structures can also be used to move atoms in materials. ...
Research shows graphene forms electrically charged crinkles
Researchers from Brown University have discovered another peculiar and potentially useful property of graphene, one-atom-thick sheets of carbon, that could be useful in guiding nanoscale self-assembly or in analyzing DNA ...
Iron-rich minerals on Mars could contain life's fatty acids
A little stream in the south of England could guide the way towards finding evidence for ancient life on Mars, in the form of fatty acids preserved in an iron-rich mineral called goethite.
Scientists peep deep into a diamond to examine its defects
Researchers take a deep look into a diamond to see how the atoms in its platelet defects are arranged in the hardest natural material known to man.
Tracking down the reactivity of catalysts
An international team of chemists has found a method to accelerate the development of new catalysts. Using NMR spectroscopy together with computational chemisty, they can evaluate whether or not molecules can enable reactions.
