Foam 'fizzics'

Chemical engineers at the University of Illinois Chicago and UCLA have answered longstanding questions about the underlying processes that determine the life cycle of liquid foams. The breakthrough could help improve the ...

An invisible keyhole via transparent electronics

Hard times for burglars and safecrackers: Empa researchers have developed an invisible "keyhole" made of printed, transparent electronics. Only authorized persons know where to enter the access code.

Wider horizons for highly ordered nanohole arrays

Scientists from Tokyo Metropolitan University have developed a new method for making ordered arrays of nanoholes in metallic oxide thin films using a range of transition metals. The team used a template to pre-pattern metallic ...

Thin explosive films provide snapshot of how detonations start

Using thin films—no more than a few pieces of notebook paper thick—of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow. Sandia is the only lab ...
