Compact radar takes an inside view

The human eye cannot see through wood, paper, or plastic. But a compact radar with a modular design now makes it possible to see the invisible: The millimeter wave sensor penetrates non-transparent material. It transmits ...

All-inorganic nanocrystals boost infrared emission

New chemistry has been developed to integrate lead chalcogenide nanocrystals into continuous inorganic matrices of chalcogenide glasses. Inorganic capping, rather than conventional organic capping ligands, allows simple and ...

Physicists scale up invisibility cloaks using natural crystals

(PhysOrg.com) -- Physicists from the University of Birmingham, with colleagues at Imperial College, London, and Technical University of Denmark, have demonstrated an 'invisibility cloak' that can hide a three-dimensional ...

Plasma as a fast optical switch

Laser uses relativistic effects to turn otherwise opaque plasma transparent, creating an ultra-fast optical switch useful in next-generation particle accelerators.

Nanometer Graphene Makes Novel OLEDs Display

Researchers at Stanford University have successfully developed brand new concept of organic lighting-emitting diodes (OLEDs) with a few nanometer of graphene as transparent conductor. This paved the way for inexpensive mass ...
