Reversible doping: Hydrogen flips switch on vanadium oxide

If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks to a new study ...

Single molecule can shift the phase of a laser beam

(PhysOrg.com) -- The ability to control light forms the basis of many technologies, from microscopy to optical computing. Now, a team of scientists from ETH in Zurich, Switzerland, has demonstrated that a single organic molecule ...

Magnetic switching under pressure

(PhysOrg.com) -- A material’s properties are a critical factor in the way that material can be used for practical applications. Magnetism is one such property, and magnetic switches are key components for advances in ...

Researchers program cells to be remote-controlled by light

(PhysOrg.com) -- UCSF researchers have genetically encoded mouse cells to respond to light, creating cells that can be trained to follow a light beam or stop on command like microscopic robots.
