Squeezable nano electromechanical switches with quantum tunneling function
A longstanding problem in designing nanoscale electromechanical switches is the tendency for metal-to-metal contacts to stick together, locking the switch in an "on" position. MIT electrical engineering graduate ...
Atomic placement of elements counts for strong concrete
Even when building big, every atom matters, according to new research on particle-based materials at Rice University.
Fraud-proof credit cards possible with quantum physics
Credit card fraud and identify theft are serious problems for consumers and industries. Though corporations and individuals work to improve safeguards, it has become increasingly difficult to protect financial ...
Supercomputers reveal strange, stress-induced transformations in world's thinnest materials
(Phys.org) —Interested in an ultra-fast, unbreakable, and flexible smart phone that recharges in a matter of seconds? Monolayer materials may make it possible. These atom-thin sheets—including the famed ...
Consider the 'anticrystal'
(Phys.org) —For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent ...
Physicists use geometry to understand 'jamming' process
(Phys.org) —University of Oregon physicists using a supercomputer and mathematically rich formulas have captured fundamental insights about what happens when objects moving freely jam to a standstill.
Teleported by electronic circuit: Physicists 'beam' information
ETH-researchers cannot "beam" objects or humans of flesh and blood through space yet, a feat sometimes alluded to in science fiction movies. They managed, however, to teleport information from A to B – for the first time ...
Tetrapod nanocrystals light the way to stronger polymers
Fluorescent tetrapod nanocrystals could light the way to the future design of stronger polymer nanocomposites. A team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory ...
A robot that runs like a cat (w/ Video)
Thanks to its legs, whose design faithfully reproduces feline morphology, EPFL's 4-legged 'cheetah-cub robot' has the same advantages as its model: It is small, light and fast.
