A technique which may one day be used for tumor therapy and imaging could be greatly improved thanks to new insights obtained by scientists from the University of Twente, the Erasmus MC and the TU Delft.
Due to the particular uncertainties concerning evaluation of the possible risks of nanomaterials for human health and the environment, the German Federal Environment Agency (Umweltbundesamt) supports the establishment of a European register of products containing nanomaterials as a precautionary measure.
An international collaboration has made significant progress in modelling how electric currents affect the magnetization in some current-switched magnetic devices. While a number of such devices hold promise as low energy electronics, progress on some of the latest ideas has been impeded because different and contradictory models have been proposed to understand how they work and how to best optimize their performance.
The first 'unambiguous demonstration' of the atomic-scale sound waves known as phonons crossing over from particle-like to wave-like behavior in superlattices opens the door to improved thermoelectrics and possibly even phonon lasers.
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature - a property known as ballistic transport.
