Much as a frame provides structural support for a house and the chassis provides strength and shape for a car, a team of engineers believes they have a way to create the structural framework for growing living tissue using an off-the-shelf 3-D printer.
Researchers have created glass that lets through a large amount of light while appearing hazy, a combination of properties that could help boost the performance of solar cells and LEDs.
The way in which electronic devices operate relies on the interaction between various materials. For this reason, researchers need to know exactly how specific chemical elements inside a computer chip or a transistor diode behave, and what happens when these elements bond. Physicists have now developed an innovative method that enables them to obtain several different types of information simultaneously from the interior of a nanoscale building block, and this while it is in the active state.
You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a research team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account.
Researchers have presented a new design that, in tests, enabled gallium nitride power devices to handle voltages of 1,200 volts. That’s already enough capacity for use in electric vehicles, but the researchers believe that further work can boost its capacity to the 3,300-to-5,000-volt range, to bring the efficiencies of gallium nitride to the power electronics in the electrical grid itself.
A printing process uses natural forces to grow an inexpensive catalyst to replace platinum to lower the cost of hydrogen-powered cars, report researchers.
Mobile phone speakers and motion detectors in cars and video games may soon be powered by electricity generated from low cost and sustainable biomaterials, according to new research.
Solar power could transform small communities around the world, but remote villages can’t always scrape together the thousands of dollars required to install the cells. The Sun Exchange wants to change that by leveraging the hearts and wallets of hobby investors, who cover the installation costs and then have their share of the revenue trickle in for years to come. There’s even… Read More
Automakers are laying the groundwork for a future in which electric cars are omnipresent – and at least as common a sight on roadways as traditional gas-powered vehicles. Last month, a group of car OEMs including Ford, BMW, Daimler, and Volkswagen Group created a new joint-venture called ‘Ionity’ to build out a charing network, starting with a series of fast-charging stations… Read More
Some carmakers are talking a lot about the potential of shared mobility services and alternatives to car ownership, but Volkswagen’s MOIA is actually going a step further, with a brand new vehicle it’s unveiling today that’s focused entirely on this new market. The all-electric car, which made its debut at TechCrunch Disrupt Berlin today, is designed to provide maximally… Read More
