What limits the behaviour of a carbon nanotube? This is a question that many scientists are trying to answer. Physicists at University of Gothenburg, Sweden, have now shown that electromechanical principles are valid also ...
Sandia National Laboratories researcher Steve Plimpton, who led development of a widely used computer code that models how materials behave, has been invited to present a keynote lecture at the Feb. 27-March 3 Minerals, Materials ...
When water freezes or boils, its atomic structure undergoes a phase transition in response to temperature change. Phase transitions are common in nature, and have been exploited to make devices such as digital memories. Complex ...
(PhysOrg.com) -- In a study published in the July 1 issue of the journal Nature, Dartmouth researchers describe one example of the microscopic quantum world influencing--even dominating, they say--the behavior of something ...
(PhysOrg.com) -- “Most current hard x-ray interferometers are based on crystals, which require their high quality and high mechanical stability,” Anatoly Snigirev tells PhysOrg.com. “This can make x-ray interferometry ...
One of the issues affecting quantum systems is coherence. Understanding coherence and how it breaks down (decoherence) is one of the keys to putting together a powerful quantum computer. And, because wires made from metal ...
(PhysOrg.com) -- When physicists entangle light, they usually use nonlinear crystals as the source. However, it’s difficult to control the entanglement generation process in a bulk crystal, and so scientists have been looking ...
Lawrence Livermore National Laboratory researchers have captured time-series snapshots of a solid as it evolves on the ultra-fast timescale.
Layers of plastic, much thinner than a strand of hair—this type of ultrathin polymer film is of great interest to scientists and engineers. Applications include protective coatings, for example. A research team led by Stefan ...
Solar cell technology is marching ahead, though it still struggles with the two problems: efficiency and high production costs. In collaboration with Satoshi Uchida at the University of Tokyo, Michael Grätzel and his research ...
