Due to the delocalization of molecular orbitals valence shell spectroscopy does not allow distinction between individual atoms. Here, the authors show that for photoionization the difference in mass - and hence recoil momentum - between atoms in a diatomic molecule allows site selective emission to be observed.

A device created by electrical engineers uses a thin film of vanadium dioxide on a titanium dioxide substrate to create an oscillating switch. When a second similar oscillating system was added, over time the two devices would begin to oscillate in unison. This coupled system could provide the basis for non-Boolean computing.

Physicists have developed a new ultrafast light source for observing electron motion in molecules - made up of nuclei and electrons - at the point before the nuclei start to move. By being able to observe what actually happens, scientists can begin to understand how an electron interacts with other electrons, which may help improve the efficiency of solar cells.
