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 by physicists at Rice University, scientists have a new way to reversibly alter VO2's electronic properties by treating it with one of the simplest substances -- hydrogen.

Carbon nanotubes have promised some incredible advances in power efficiency, but one of the most promising (and most realistic) is boosting the capacity of lithium-ion batteries by a factor of two in the near term, and eventually by five.

Beyond the high-speed hard drive: Topological insulators open a path to room-temperature spintronics
Theorists and experimenters have explored the unique properties of topological insulators, where electrons may flow on the surface without resistance, with spin orientations and directions intimately related. Recent research opens exciting prospects for practical new room-temperature spintronic devices that can exploit control of electron spin as well as charge.

Good vibes: Coupling electron spin states and carbon nanotube vibrations
(Phys.org) -- An electron’s spin is separate from its motion, and is suitable for use in both highly-precise magnetic sensing as well as a qubit in quantum computing. Recently, scientists at the University of Konstanz in Germany have theoretically investigated the coupling of electron spin in carbon nanotube quantum dots, showing that the carbon nanotube’s nanomechanical vibrations can ...

New nanostructure for batteries keeps going and going
(Phys.org) -- For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless.
