Two-dimensional semiconductor comes clean
In 2013 James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering, and colleagues at Columbia demonstrated that they could dramatically improve the performance of graphene—highly ...
'Phonon tunneling' explains heat flow across nanometer-wide gaps, study finds
Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea ...
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 ...
'Solid' light could compute previously unsolvable problems
Researchers at Princeton University have begun crystallizing light as part of an effort to answer fundamental questions about the physics of matter.
Researchers inspired by marine life to design camouflage systems (w/ Video)
It could be a fun party trick – put your cell phone down on a table and watch it fade into the woodwork – or part of a lifesaving technology used by industry or the military.
Researchers develop treated surfaces that can actively control how fluids or particles move (w/ Video)
Researchers at MIT and in Saudi Arabia have developed a new way of making surfaces that can actively control how fluids or particles move across them. The work might enable new kinds of biomedical or microfluidic ...
Law of physics governs airplane evolution
Researchers believe they now know why the supersonic trans-Atlantic Concorde aircraft went the way of the dodo—it hit an evolutionary cul-de-sac.
Material generates steam under solar illumination
A new material structure developed at MIT generates steam by soaking up the sun.
Phase-changing material could allow low-cost robots to switch between hard and soft states
In the movie "Terminator 2," the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now a phase-changing material built from wax and foam, ...
Carbon-fiber epoxy honeycombs mimic the material performance of balsa wood
In wind farms across North America and Europe, sleek turbines equipped with state-of-the-art technology convert wind energy into electric power. But tucked inside the blades of these feats of modern engineering ...
New manufacturing methods needed for 'soft' machines, robots
Researchers have developed a technique that might be used to produce "soft machines" made of elastic materials and liquid metals for potential applications in robotics, medical devices and consumer electronics.
New super waterproof surfaces cause water to bounce like a ball
(Phys.org) —In a basement lab on BYU's campus, mechanical engineering professor Julie Crockett analyzes water as it bounces like a ball and rolls down a ramp.
New material coating technology mimics nature's lotus effect (w/ video)
Ever stop to consider why lotus plant leaves always look clean? The hydrophobic – water repelling – characteristic of the leaf, termed the "Lotus effect," helps the plant survive in muddy swamps, repelling ...
First phononic crystal that can be altered in real time
Using an acoustic metadevice that can influence the acoustic space and can control any of the ways in which waves travel, engineers have demonstrated, for the first time, that it is possible to dynamically ...
