Adding vanadium to lithium-ion batteries makes it possible to charge them “in a matter of minutes”
Many investigators have looked for alternatives to lithium-ion batteries, with others seeking out ways to tweak the performance of the existing energy storage devices. A recent study by researchers at the Rensselaer Polytechnic Institute (RPI) in New York suggests using vanadium in the battery’s cathode. This will result in the cell charging much faster while still storing a considerable […]

How does a metal light enough to be moved by humans become explosion proof?
German researchers took cues from bones when developing their new open-cell metal foams. Not only are the new materials incredibly light, they also have the strength to withstand the impact of vehicular accidents and even an explosion. The Saarland University team applied their coating process to a lattice substrate of aluminum or polymer foam. The […]

Researchers find way to harvest electricity from bacteria
A Swedish-led research group succeeded in increasing the amount of electrical current that they can harvest from bacteria. The jump in efficiency is a big step toward the use of bacteria as sources of clean and renewable energy. In light of the dwindling supply of fossil fuels and the increasing demand for energy, researchers are exploring potential sources […]

Plane privacy: Researchers invent new toilet to make flushing in airplanes whisper-quiet
Nervous frequent flyers and jumpy kids may soon get some peace of mind while using the toilet on an airplane. It took a lot of tries, but researchers finally developed relatively simple ways to reduce the noise made by a flushing toilet. A team of physicists from Brigham Young University (BYU) spent two years adjusting different parts […]

New camera boasts frame rate of 10 trillion fps, captures light as it travels
If you ever wanted to see what light looks like as it travels through air, you would need the femtosecond streak camera developed by California-based researchers. The fastest optical instrument in the world, it snaps a staggering 10 trillion frames per second. Developed by researchers from the National Institute of Scientific Research (INRS) and the […]

Engineers miniaturize spectrometers – coming to a phone near you
Researchers have recently presented a prototype spectrometer that integrates with a digital camera to scan substances for the presence of chemicals. The micronized version of the versatile optical instrument might one day become another common feature in mobile devices. A spectrometer is a type of light-based sensor that searches for the presence of chemicals and […]

Grow your own cup: Biodegradable cups made from gourds may end single-use coffee cups
A New York-based design company called Creme is doing its part to reduce the amount of plastic trash churned out each year. Instead of manufacturing disposable coffee cups with plastic liners, the start-up grows biodegradable, organic containers from fruits. For their project, Creme picked gourds from the Cucurbitaceae family. Related to squash and pumpkins, these […]

Biodegradable “transparent” timber works just as well as glass in windows
Swedish researchers fiddled with wood until they managed to turn it technically transparent. They also made the biodegradable material capable of absorbing heat from sunlight and releasing it during colder periods. If used in the windows of buildings, the revolutionary material might help save energy by reducing the need for artificial heating and cooling. It […]

Scientists develop liquid that changes color with heat
Thermochromic materials are “smart” materials that change their color depending on the temperature of their surroundings. Recently, a Singaporean research team presented a liquid that grew much darker as it got hotter. Their invention might prove useful in smart windows and other applications that respond to temperature changes. Unlike earlier examples that relied on dyes […]

The Jetsons are here: Flying, driverless car takes its first test flight in Vienna
For the first time in Europe, a Chinese-designed flying taxi took to the skies over Vienna, Austria. Its developers claimed that the small test flight for the mega-drone represented a giant leap for urban mobility. The Ehang 216 self-flying taxi performed its maiden European flight at the Generali Arena in the Austrian capital. It flew in circles […]
