'Stealth' material hides hot objects from infrared eyes

ScienceDaily.com: Nanotechnology News - 11 hours 57 min назад
Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible.

The photoelectric effect in stereo

Nanowerk.com - 22 июня, 2018 - 20:11
In the photoelectric effect, a photon ejects an electron from a material. Researchers have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce the exact location of a photoionization event.
