Coating cancels acoustic scattering from odd-shaped objects


In a new twist, a team of researchers from the U.S. Naval Research Laboratory and the University of Texas at Austin has applied to acoustic waves the concept of "scattering cancellation," which has long been used to systematically cancel the dominant scattering modes of electromagnetic waves off ...


Super-slick material makes steel better, stronger, cleaner

Researchers design most durable anti-fouling material to date


While various grades of steel have been developed over the past 50 years, steel surfaces have remained largely unchanged. The steel of today is as prone as ever to the corrosive effects of water and salt and abrasive materials such as sand. Steel surgical tools can still carry microorganisms that ...

An engineered surface unsticks sticky water droplets


The leaves of the lotus flower have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to ...


Glass paint could keep metal roofs and other structures cool even on sunny days


Sunlight can be brutal. It wears down even the strongest structures, including rooftops and naval ships, and it heats up metal slides and bleachers until they're too hot to use. To fend off damage and heat from the sun's harsh rays, scientists have developed a new, environmentally friendly paint ...

Nanowire clothing could keep people warm - without heating everything else


To stay warm when temperatures drop outside, we heat our indoor spaces - even when no one is in them. But scientists have now developed a novel nanowire coating for clothes that can both generate heat and trap the heat from our bodies better than regular clothes. They report on their technology, ...
