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 ...

Coating plastics with porous nanofilm

Pore size in porous materials affects the property of the material. For example, small pores create more absorbent surface areas. Silica gel, which is often used in food packaging to soak up moisture, is one typical example.
