Controlling heat flow through a nanostructure
MIT researchers find that heat moving in materials called superlattices behaves like waves; finding could enable better thermoelectrics.
Could tailored golf balls improve putting performance?
Golfers could get tailored golf balls with more precise separation control for the best performance, new research suggests.
A new stable and cost-cutting type of perovskite solar cell
Perovskite solar cells show tremendous promise in propelling solar power into the marketplace. The cells use a hole-transportation layer, which promotes the efficient movement of electrical current after exposure to sunlight. ...
Researchers identify one of world's thinnest piezoelectric materials
There are a handful of naturally occurring materials, known as piezoelectric materials, that generate electricity if you bend, stretch or apply another mechanical force to them, and vice versa – if you ...
Mathematical models explain how a wrinkle becomes a crease
Wrinkles, creases and folds are everywhere in nature, from the surface of human skin to the buckled crust of the Earth. They can also be useful structures for engineers. Wrinkles in thin films, for example, ...
Scientists seek to develop new imaging capabilities to view a human virus in action
Virginia Tech Carilion Research Institute scientists Deborah Kelly and Sarah McDonald are ambitious and determined, and it's paying off.
Explained: How does a soccer ball swerve?
It happens every four years: The World Cup begins and some of the world's most skilled players carefully line up free kicks, take aim—and shoot way over the goal. The players are all trying to bend the ...
Chemical sensor on a chip
Using miniaturized laser technology, a tiny sensor has been built at the Vienna University of Technology which can test the chemical composition of liquids.
Six more bugs found in popular OpenSSL security tool
Computer system administrators around the world are groaning again as six new security problems have been found in the OpenSSL security library. ...
Count of new chlorofluorocarbons in the atmosphere rises from four to seven
Scientists at the University of East Anglia have found two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) in the atmosphere.
Heartbleed-like Cupid poses opportunity for wireless attack
Using nature as a model for low-friction bearings
The mechanical properties of natural joints are considered unrivalled. Cartilage is coated with a special polymer layer allowing joints to move virtually friction-free, even under high pressure. Using simulations ...
How cosmic crashes could have kickstarted plate tectonics
A rock the size of a small city hurtles towards Earth, smashing a crater bigger than the span between Washington, D.C. and New York City. The heat and shockwave raises the temperature of the atmosphere above ...
3D printing: The shape of things to come?
(Phys.org) —If you ask the proverbial man or woman in the street what they understand by the terms 'stereolithography', 'selective laser sintering' and 'fused deposition modelling', you're likely to be ...
