In some circles, memristors (from "memory resistor," as coined by Leon Chua in a 1971 paper outlining memristive theory) are all the rage – and for good reason: As circuit elements which "remember" the amount of current ...
(PhysOrg.com) -- GE's technology research group has announced the development of an optical disc writer capable of writing 500 GB of data onto a disc the same physical size as a DVD, at roughly the same speed as Blue Ray ...
With several new models of electric vehicles hitting the market this year and more next year, President Obama’s goal of putting 1 million EVs on U.S. roads by 2015 is tantalizingly within grasp. But what will it take ...
With the silent attentiveness of a physician, Ivy Nguyen passes her hands over the recumbent white lady in the darkened lab. She cradles a handheld black light in her fingers.
It's a problem that materials scientists have considered for years: how does a material composed of more than one phase evolve when heated to a temperature that will allow atoms to move? In many cases, a rod-like phase embedded ...
(PhysOrg.com) -- Sometimes the simplest things hold the key to understanding complex effects. It turns out that a humble metal pull-chain -- just like those used on ceiling fans -- can be a pretty good model for complex properties ...
(PhysOrg.com) -- Virtually every patient diagnosed with breast cancer or melanoma undergoes lymph node biopsy to determine if their cancer has begun spreading in the body. Taking this biopsy involves an invasive and uncomfortable ...
(PhysOrg.com) -- Cornell researchers are devising methods to detect the magnetic fields of individual electrons and atomic nuclei, which they hope to use to make a nanoscale version of magnetic resonance imaging.
Imagine using the same process that goes into building video games to help investigators solve real-world crimes. Through a new grant, that's what researchers at North Carolina State University plan to do. Their work will ...
(PhysOrg.com) -- IBM scientists have demonstrated a promising and practical method that effectively eliminates the mechanical wear in the nanometer-sharp tips used in scanning probe-based techniques. This discovery can potentially ...
