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.
Potential side effects of many of today's therapeutic drugs can be downright frightening - just listen carefully to a drug commercial on TV. These effects often occur when a drug is active throughout the body, not just where and when it is needed. But scientists are reporting progress on a new tailored approach to deliver medicine in a much more targeted way.
By sandwiching a biological molecule between sheets of graphene, researchers at the University of Illinois at Chicago have obtained atomic-level images of the molecule in its natural watery environment.
