Nano oscillators synchronized by light

(Phys.org)—Synchronization phenomena are everywhere in the physical world—from circadian rhythms to side-by-side pendulum clocks coupled mechanically through vibrations in the wall. Researchers have now demonstrated synchronization ...

Switching with a few photons for quantum computing

(Phys.org)—Quantum computing, where bits of information, or "qubits," are represented by the state of single atomic particles or photons of light, won't be of much use unless we can read the results. Cornell researchers ...

'Ordered' catalyst boosts fuel cell output at lower cost

(Phys.org)—Fuel cells, which convert fuel directly into electricity without burning it, promise a less polluted future where cars run on pure hydrogen and exhaust nothing but water vapor. But the catalysts that make them ...

New method knocks out stubborn electron problem

A newly published article in Physical Review Letters eliminates one of the top unsolved theoretical problems in chemical physics as ranked by the National Research Council in 1995. Scientists now can more accurately predict ...

Nanocrystal infrared LEDs can be made cheaply

(Phys.org) -- Light-emitting diodes at infrared wavelengths are the magic behind such things as night vision and optical communications, including the streaming data that comes through Netflix. Cornell researchers have advanced ...

Ferroelectric oxides do the twist

(Phys.org) -- Some materials, by their nature, do what we want them to do -- notably, the ubiquitous, semiconducting silicon found in almost every electronic device. But sometimes, naturally occurring materials need a little ...

Slow road to stability for emulsions

By studying the behavior of tiny particles at an interface between oil and water, researchers at Harvard have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought.
