Scientists have made the first observation of the electronic structure in silver-rhodium (Ag-Rh) alloy nanoparticles to investigate why the alloy possesses a hydrogen absorbing/storage property like palladium does, given that bulk Ag and Rh do not form an alloy, and that neither element alone is a hydrogen absorbing/storage metal.

Read moreScientists have succeeded in simultaneously observing the reorganizations of atomic positions and electron distribution during the transformation of the 'smart material' vanadium dioxide from a semiconductor into a metal - in a timeframe a trillion times faster than the blink of an eye. This marks the first time experiments have been able to distinguish changes in a material's atomic-lattice structure from the relocation of the electrons in such a blazingly fast process.

The trend toward energy self-sufficient probes and ever smaller mobile electronics systems continues unabated. They are used, for example, to monitor the status of the engines on airplanes, or for medical implants. They gather the energy they need for this from their immediate environment - from vibrations, for instance. Researchers have developed a process for the economical production of piezoelectric materials.
