A future colourfully lit by mystifying physics of paint-on semiconductors

It defies conventional wisdom about semiconductors. It's baffling that it even works. It eludes physics models that try to explain it. This newly tested class of light-emitting semiconductors is so easy to produce from solution that it could be painted onto surfaces to light up our future in myriad colours shining from affordable lasers, LEDs, and even window glass. Some novel materials that sound too good to be true turn out to be true and good. An emergent class of semiconductors, which ...

Scientists create microscopic 'swimmers' controlled by a magnetic field

What are those tiny spheres doing as they move across that slide? They're doing the breaststroke. Rice University scientists have discovered what may be the simplest form of locomotion in the travels of micron-scale particles linked and driven by a magnetic field. In the Rice lab of chemical and biomolecular engineer Sibani Lisa Biswal, researchers placed magnetised spheres of different sizes into a solution. When subjected to an "eccentric magnetic field", the spheres self-assembled ...

Researchers confirm century-old speculation on chemistry of high-performance battery

Scientists have discovered a novel chemical state, first proposed about 90 years ago, that enables a high-performance, low-cost sodium-ion battery. The battery could quickly and efficiently store and distribute energy produced by solar panels and wind turbines across the electrical grid. This direct proof of a previously unconfirmed charge state in a manganese-containing battery component could inspire new avenues of exploration for battery innovations. X-ray experiments at the US ...

Water filtration breakthrough using metal-organic frameworks

With two billion people worldwide lacking access to clean and safe drinking water, joint research by Monash University, the Commonwealth Scientific and Industrial Research Organization (CSIRO) and the University of Texas at Austin, and published recently in 'Sciences Advances', may offer a breakthrough new solution. Sponge-like crystals can be used to capture, store and release chemical compounds It all comes down to metal-organic frameworks (MOFs), an amazing next generation ...

Graphene on toast, anyone?

Rice University scientists who introduced laser-induced graphene (LIG) have enhanced their technique to produce what may become a new class of edible electronics. The Rice lab of chemist James Tour, which once turned Girl Scout cookies into graphene, is investigating ways to write graphene patterns onto food and other materials to quickly embed conductive identification tags and sensors into the products themselves. 'This is not ink' "This is not ink," Tour said. "This is taking ...

How a thermal resonator takes advantage of swings in temperature to produce electricity

Thermoelectric devices, which can generate power when one side of the device is a different temperature from the other, have been the subject of much research in recent years. Now, a team at MIT has come up with a novel way to convert temperature fluctuations into electrical power. Instead of requiring two different temperature inputs at the same time, the new system takes advantae of the swings in ambient temperature that occur during the day-night cycle. No requirement for power ...
