Lithium-metal batteries have not hit the market yet, but if they do, they could be a solution to the everyday woes of the dwindling battery meter. They are cousins of the lithium-ion batteries found in legions of everyday electronic devices, but with the potential to hold twice as much power. Unfortunately, the lithium-metal battery’s limited number of recharges has been a major obstacle to their wide adoption.

A new study led by researchers at the California NanoSystems Institute at UCLA, or CNSI, however, might just help ratchet up the pace of progress. In the journal Science Advances, the team documented an they invented that—for the first time ever—captures a lithium-metal battery as it charges, at a level of detail smaller than the wavelength of light.

The method, electrified , or eCryoEM for short, yielded insights that may help guide the design of better lithium-metal batteries. Cultivating this progress with U.S.-based research could give the U.S. an edge in this successor technology to , an industry currently dominated by Chinese enterprises. The study also holds promise for shedding light on mysteries in disciplines as far afield as neuroscience.

Silicon is king in the semiconductor technology that underpins smartphones, computers, electric vehicles and more, but its crown may be slipping, according to a team led by researchers at Penn State.

In a world first, they used two-dimensional (2D) materials, which are only an atom thick and retain their properties at that scale, unlike , to develop a computer capable of simple operations.

The development, published in Nature, represents a major leap toward the realization of thinner, faster and more energy-efficient electronics, the researchers said.

Lithium-ion batteries power everything from electric cars to laptops to leaf blowers. Despite their widespread adoption, lithium-ion batteries carry limited amounts of energy, and rare overheating can lead to safety concerns. Consequently, for decades, researchers have sought a more reliable battery.

Solid-state batteries are less flammable and can hold more energy, but they often require intense pressure to function. This requirement has made them difficult to use in applications, but new research from Georgia Tech could change that.

The research group of Matthew McDowell, professor and Carter N. Paden Jr. Distinguished Chair in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering, has designed a new metal for solid-state batteries that enables operation at lower pressures. While is often used in these batteries, McDowell’s group discovered that combining lithium with softer metal results in improved performance and novel behavior.

A team of engineers, AI specialists and chip design researchers at the Chinese Academy of Sciences has designed, built and tested what they are describing as the first AI-based chip design system. The group has published a paper describing their system, called QiMeng, on the arXiv preprint server.

Over the past several decades, integrated circuit makers have developed systems for developing processor chips for computers, smartphones and other . Such systems tend to be made up of large teams of highly skilled people who can take design ideas (such as faster computing or running AI apps) and turn them into physical designs that can be fabricated in specially designed factories. The process is notoriously slow and expensive.

More recently, computer and device makers have been looking for ways to speed up the process and to allow for more flexibility—some may want a chip that can do just one thing, for example, but do it really well. In this new study, the team in China has applied AI to the problem.

When the computer or phone you’re using right now blinks its last blink and you drop it off for recycling, do you know what happens?

At the recycling center, powerful magnets will pull out steel. Spinning drums will toss aluminum into bins. Copper wires will get neatly bundled up for resale. But as the conveyor belt keeps rolling, tiny specks of valuable, lesser-known materials such as gallium, indium and tantalum will be left behind.

Those tiny specks are critical materials. They’re essential for building new technology, and they’re in short supply in the U.S. They could be reused, but there’s a problem: Current recycling methods make recovering from e-waste too costly or hazardous, so many recyclers simply skip them.

More people believe misinformation about electric vehicles (EVs) than disagree with it, according to surveys of four countries, including Australia, Germany, Austria, and the US. The survey found having a conspiracy mentality was the main factor influencing such beliefs, the authors say.

The main -related concerns for Australians included that EVs are more likely to catch fire, that EVs are intentionally complex to prevent DIY, and that batteries are deliberately non-upgradeable. The authors also found that fact sheets and dialogues with AI-chatbots helped reduce belief in misinformation and increased pro-EV policy support and purchase intentions.

A University of Queensland-led study published in the journal Nature Energy has found misinformation about (EVs) has taken root in society and is primarily fueled by mistrust and .

As solar energy becomes more affordable and widespread, farmland has emerged as a prime location for large-scale solar development. But with this expansion comes a persistent question: Do nearby property values suffer when solar farms move in?

In a paper published in the Proceedings of the National Academy of Sciences, researchers in Virginia Tech’s Department of Agricultural and Applied Economics in the College of Agriculture and Life Sciences looked at millions of property sales and thousands of commercial solar sites to shed some light on one of the most commonly cited downsides of large-scale solar adoption.

“As the U.S. scales up renewable energy, are increasingly being sited near homes and on farmland, and this often leads to pushback from residents worried about aesthetics or property value loss,” said Chenyang Hu, a graduate research assistant in the Department of Agricultural and Applied Economics and the paper’s lead author.

In a study published in Cell Reports Sustainability, researchers conducted the most comprehensive analysis to date on lithium supply and demand in China, Europe, and the U.S. Despite the fact that domestic lithium production in some of these regions could grow as much as 10 times by 2030, it would still fall short of the soaring demand for electric vehicles (EVs) without expanding imports or technological innovation.

“Lithium today is as important as gasoline in the ,” says author Qifan Xia of East China Normal University in Shanghai. “While reserves are substantial around the world, they are distributed unevenly across different countries. So, we were interested in whether the major EV markets could be self-sufficient.”

Together, China, Europe and the U.S. account for 80% of the world’s EV sales, and their demand is expected to increase further. The team estimated that China might need up to 1.3 million metric tons of lithium carbonate equivalent—a standard measure of lithium content—to produce new EVs. Europe might require 792,000 metric tons, followed by 692,000 metric tons for the U.S.

The government has announced a record £2.5 billion investment in fusion energy, which includes support for a prototype fusion energy plant in Nottinghamshire.

The new prototype plant, known as STEP (Spherical Tokamak for Energy Production) will be built at the site of the former West Burton A coal power station near Retford and Gainsborough. The site was chosen by the government in 2022 as the location for the project, with the project’s delivery expected to create over 10,000 jobs ranging from construction to operations. The announcement shows the government’s firm commitment to becoming a “clean energy superpower” by turbocharging innovation in an area that’s produced conventional power for generations.

The record funding for fusion research announced this week shows the UK government’s firm commitment to clean, sustainable energy.
