Ultrafast Electron Microscopy to Observe Switchable Nanochannels

Ultrafast electron microscopy reveals switchable nanochannels in materials Microscopic fissures in a tiny crystal open and close-on command. Researchers led by Ahmed H. Zewail successfully used ultrafast electron microscopy (UEM) to observe nanoscopic structures at their “exercises”, as they report in the journal Angewandte Chemie. Such switchable nanochannels could be useful for future nanoelectronics and nanoscopic “machines”.

UV Laser for Drilling and Micromachining Applications

The new AVIA 355-7 from Coherent, Inc. is a Q-switched, frequency-tripled, solid-state laser delivering over 7 Watts of average power at 355 nm, in a package designed to maximize reliability for a minimum cost of ownership. The highest average power is achieved at repetition rates near 60 kHz, but the laser can be operated at pulse rates as high as 100 kHz, enabling very high throughput micromachining processes.

New Radiation Source Could Improve Cancer Detection and Border Security

Going through airport security can be such a hassle. Shoes, laptops, toothpastes, watches and belts all get taken off, taken out, scanned, examined, handled and repacked. But "T-rays", a completely safe form of electromagnetic radiation, may reshape not only airport screening procedures but also medical imaging practices.
