Atomic structure of ultrasound material not what anyone expected

Lead magnesium niobate (PMN) is a prototypical "relaxor" material, used in a wide variety of applications, from ultrasound to sonar. Researchers have now used state-of-the-art microscopy techniques to see exactly how atoms ...

Three's company: New alloy sets magnetism benchmark

The burgeoning field of spintronics leverages electron spins—as opposed to their charge—to enhance solid-state devices like hard drives and cell phone components by prolonging battery life. Spintronic developments, however, ...

A new radiation detector made from graphene

Graphene is a remarkable material: light, strong, transparent and electrically conductive. It can also convert heat to electricity. Researchers have recently exploited this thermoelectric property to create a new kind of ...

New research advances spintronics technology

Engineers at the University of California, Riverside, have reported advances in so-called "spintronic" devices that will help lead to a new technology for computing and data storage. They have developed methods to detect ...

Computer models reveal best way to kill deadly bacteria

Bacteria, transformed into dormant spores, can survive millions of years in extreme environments, threatening human life in the form of food poisoning and the biological weapon anthrax. But understanding how bacteria adapt ...
