Tiny transistors for extreme environs

Electrical engineers fabricated the smallest plasma transistors that can withstand high temperatures and ionizing radiation found in a nuclear reactor. Such transistors someday might enable smartphones that take and collect medical X-rays on a battlefield, and devices to measure air quality in real time.

'Nano-flares' catch early spread of breast cancer

When cancer spreads from one part of the body to another, it becomes even more deadly. It moves with stealth and can go undetected for months or years. But a new technology that uses 'nano-flares' has the potential to catch these lurking, mobilized tumor cells early on.

SWARPES sheds light on the scientific potential for remote microscopy

To unlock the vast potential of metal oxide interfaces, especially those buried in subsurface layers, scientists need even more detailed knowledge of their electronic structure. And a new technique - called SWARPES, for Standing Wave Angle-Resolved Photoemission Spectroscopy - promises to deliver the goods.

Why do Li-ion batteries age?

Even the best Li-ion batteries degrade with time. A reason for this was now identified by researcher. They could directly observe atomic rearrangements occurring in the cathode material of Li-ion batteries during charge and discharge processes.
