In the field of nanotechnology, electrically-charged particles are frequently used as tools for surface modification. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Vienna were at last able to reconcile important issues concerning the effects of highly charged ions on surfaces.
Physicists have directly imaged Landau Levels - the quantum levels that determine electron behaviour in a strong magnetic field - for the first time since they were theoretically conceived of by Nobel prize winner Lev Landau in 1930.
Researchers have developed a method to measure photocurrents of a single functionalized photosynthetic protein system. The scientists could demonstrate that such a system can be integrated and selectively addressed in artificial photovoltaic device architectures while retaining their biomolecular functional properties.
By mimicking nature's own sensing mechanisms, bioengineers at UC Santa Barbara and University of Rome Tor Vergata have designed inexpensive medical diagnostic tests that take only a few minutes to perform.
In order to assemble novel biomolecular machines, individual protein molecules must be installed at their site of operation with nanometer precision. LMU researchers have now found a way to do just that. Green light on protein assembly.
