For the first time, Stanford researchers have found a way to create and stabilize an extremely rare form of gold that has lost two negatively charged electrons, denoted Au²⁺. The material stabilizing this elusive version of the valued element is a halide perovskite—a class of crystalline materials that holds great promise for various applications including more-efficient solar cells, light sources, and electronics components.

Surprisingly, the Au²⁺ perovskite is also quick and simple to make using off-the-shelf ingredients at room temperature.

“It was a real surprise that we were able to synthesize a stable material containing Au²⁺ —I didn’t even believe it at first,” said Hemamala Karunadasa, associate professor of chemistry at the Stanford School of Humanities and Sciences and senior author of the study published Aug. 28 in Nature Chemistry. “Creating this first-of-its-kind Au²⁺ perovskite is exciting. The gold atoms in the perovskite bear strong similarities to the copper atoms in high-temperature superconductors, and heavy atoms with unpaired electrons, like Au²⁺, show cool magnetic effects not seen in lighter atoms.”

New Zealand is the latest market where Tesla launched its Non-Tesla Supercharger Pilot program, which allows for the recharging of other electric vehicles at Superchargers.

According to the company, six Supercharging sites are now available for all EVs (compatible with the locally used CCS2 charging connector, natively used also by Tesla). That’s about a third of all Supercharging stations in New Zealand.

Australia was included in the program in early 2023, and currently, it seems that more than half (roughly 30 locations) were opened to all EVs.

AUSTIN (KXAN) — As the City of Austin works toward reducing its carbon footprint, city officials are working to expand programs and infrastructure to help make electric vehicle technology more accessible citywide.

Amy Atchley, senior lead with Austin Energy’s EV equity program, spoke Tuesday at MOVE America 2023, a mobility conference held in downtown Austin. Atchley’s presentation centered around providing EV access to underserved community members, particularly as the city moves toward a 2040 goal of net zero carbon emissions.

With that goal in mind, she noted transportation is the leading emitter of carbon dioxide into the atmosphere. In order to achieve that benchmark, she said the city must have at least 40% of its vehicle miles traveled done via electric vehicle technology by 2030.

Tesla’s vehicles come with various unique features, including the ability to use the mobile app to perform several different functions remotely. In a repost of another account pointing to the ability to set cabin temperature remotely, Tesla highlighted that preconditioning will also warm up the vehicle’s battery, helping to optimize range and overall performance.

On Wednesday morning, Tesla reposted a @WholeMarsBlog post on X describing the ability to pre-set cabin temperature remotely using the mobile app when it’s hot outside, meaning owners will “never get into a car that’s too hot or too cold again.”

Tesla piggybacked on the concept, pointing out that when users remotely precondition their cars during the winter, their batteries will also be warmed to the ideal temperature to improve vehicle performance.

Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun.

In a paper appearing in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.

The configuration of the device allows water to circulate in swirling eddies, in a manner similar to the much larger “thermohaline” circulation of the ocean. This circulation, combined with the sun’s heat, drives water to evaporate, leaving salt behind. The resulting water vapor can then be condensed and collected as pure, drinkable water. In the meantime, the leftover salt continues to circulate through and out of the device, rather than accumulating and clogging the system.

Water is still an issue around the world.

Engineers at MIT and China have jointly developed a solar-powered system that extracts fresh water from seawater so efficiently it is “cheaper than tap water,” says one of the researchers who invented the system. The inventors say the system could provide clean drinking water sustainably to off-grid coastal communities and families living near a sea water source.

Areas of New York City are sinking while others are rising at varying rates due to both natural and man-made factors.

One of the key indicators of climate change is the rise in sea levels at a global scale, with recent rates being unprecedented in the last 2,500 years. In an exciting study published yesterday, 27 September, NASA-based scientists found that some areas of New York City are sinking while others are rising at varying rates due to natural and man-made factors.

Interesting Engineering had reported earlier on a similar study, which said that New York is sinking due to a natural phenomenon called subsidence, where heavy objects, like buildings, gradually settle over time or when… More.

Tesla has broken ground on the site of its planned futuristic diner with a drive-in theater and Supercharger station.

Yes, it sounds like that crazy project is actually happening.

This project has been in the works for a long time. In 2018, Elon Musk said that Tesla planned to open an “old school drive-in, roller skates & rock restaurant at one of the new Tesla Supercharger locations in Los Angeles.” It was yet another “Is he joking?” kind of Elon Musk idea, but he wasn’t kidding.

The process not only shortens the time required for recycling but also reduces secondary waste streams.

The world is expected to experience a surge in battery demand as it moves to renewable energy sources. And, with the development of sustainable energy technologies, there will be a subsequent increase in the demand for precious metals used in batteries. Many of the materials used in such batteries, like lithium-ion batteries, are not available in abundance, and the best way to meet this need is to recycle old batteries.

To aid in this mission, a team of researchers at Rice University in the United States of America has developed a new recycling process that helps salvage more than 98 percent… More.
