21st May 2013: Hydrogen atoms under the magnifying glass: Direct Observation of the Nodal Structures of Electronic States of the Hydrogen Atom To describe the microscopic properties of matter and its interaction with the external world, quantum mechanics uses wave functions, whose structure and time dependence is governed by the Schrödinger equation. In atoms, electronic wave functions describe - among other things - charge distributions existing on length-scales that are many orders of magnitude removed from our daily experience. ... more.
 
15th April 2013: Neighbors move electrons jointly - an ultrafast molecular movie on metal complexes in a crystal Applying femtosecond x-ray methods, researchers at the Max-Born-Institute in Berlin (Germany) and the Ecole Polytechnique Federale de Lausanne (Switzerland) observed an extremely fast, collective electron transfer of ~100 molecular ions after excitation of a single electron in a crystal of transition metal complexes. ... more.
