Team develops a commercially viable and safe gel electrolyte for lithium batteries. Professor Soojin Park, Seoha Nam, a PhD candidate, and Dr. Hye Bin Son from the Department of Chemistry at Pohang University of Science and Technology (POSTECH) have achieved a breakthrough in creating a gel electrolyte-based battery that is both stable and commercially viable. Their research was recently published in the international journal Small.

Lithium-ion batteries are extensively utilized in portable electronics and energy storage including electric vehicles. However, the liquid electrolytes used in these batteries pose a significant risk of fire and explosion, prompting ongoing research efforts to find safer alternatives. One alternative is the semi-solid-state battery which represents a middle ground between traditional lithium-ion batteries with liquid electrolytes and solid-state batteries. By using a gel-like electrolyte, these batteries offer enhanced stability, energy density, and a relatively longer lifespan.

Hundreds of US flights were canceled Monday, as carriers, particularly Delta Air Lines, work to recover four days after a global tech outage caused massive delays and left travelers stranded at airports around the nation.

Delta is facing mounting pressure to get passengers back in the air, as it continues to rack up the majority of canceled US flights. US Transportation Secretary Pete Buttigieg has expressed frustration with the pace of Delta’s recovery and its CEO has apologized to affected travelers.

More than 900 flights into, within or out of the United States were canceled by midday Monday, and 3,100 flights were delayed, according to flight tracking site FlightAware. Delta passengers have been slammed by more than 4,500 cancellations since Friday, including 748 on Monday, by far the most of any airline.

ATCHISON, Kan. (WDAF) — It’s one of the greatest unsolved mysteries ever, but we might now be on the verge of discovering what happened to Amelia Earhart’s plane.

Earhart was born and raised in Atchison, Kansas, and her love for planes and flying drove her to break barriers for female pilots.

On June 1, 1937, she and navigator Fred Noonan made an attempt to fly around the world in a Lockheed Electra 10-E plane, but somewhere over the Pacific, they lost radio contact and were never heard from again.

How do you teach ChatGPT common sense? Train it on questions that adults would never think to ask. In this week’s “The Joy of Why,” computer scientist Yejin Choi talks with co-host Steven Strogatz about how training AI can mimic the “why-this, why-that” curiosity of a toddler.

The California High-Speed Rail Authority just received environmental approval to connect downtown Los Angeles to the Bay Area with a bullet train capable of reaching speeds of up to 200 miles per hour, KTLA5 reported.

KTLA5 called the approval “a historic milestone in a state notorious for holding up construction projects for environmental review.”

The California High-Speed Rail system is an ambitious project that has technically been in the works for decades, but it has progressed in fits and starts. Recently, however, construction began on several parts of the system. The initial segment, connecting Merced to Bakersfield in the Central Valley, could be open as soon as 2030, with much more to follow, KTLA5 reports.

A robotic truck equipped with a 105-ft (32-m) telescopic boom arm has just journeyed from Australia to Florida. Now the construction robot will get busy churning out up to 10 houses in a bid to become the employee of choice for building entire communities.

The truck and its accompanying brick-laying arm is known as the Hadrian X and has been developed by robotics company FBR, which first announced its prototype in 2015. That machine could complete a full-sized house in two days. Last year, FBR (which used to stand for Fastbrick Robotics), showed off the new Hadrian X which, at top speed, could stack 500 USA-format masonry blocks per hour.

The robotic vehicle/construction arm gets to work after it is loaded by pallets containing the blocks. Each block is then sent down a chute on the arm, painted with a quick-dry construction adhesive that takes the place of mortar, and is placed by a variable gripper at the end of the arm. Thanks to its impressive length, the arm is able to build structures that are three stories tall. Plus, because it’s a robot, it never needs to sleep or take a break if the weather turns nasty, so it can chug along pretty much 24/7.

Researchers have created a new class of materials called “glassy gels” that are very hard and difficult to break despite containing more than 50% liquid. Coupled with the fact that glassy gels are simple to produce, the material holds promise for a variety of applications.

Gels and glassy polymers are classes of materials that have historically been viewed as distinct from one another. Glassy polymers are hard, stiff and often brittle. They’re used to make things like water bottles or airplane windows. Gels – such as contact lenses – contain liquid and are soft and stretchy.

“We’ve created a class of materials that we’ve termed glassy gels, which are as hard as glassy polymers, but – if you apply enough force – can stretch up to five times their original length, rather than breaking,” says Michael Dickey, corresponding author of a paper on the work and the Camille and Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University. “What’s more, once the material has been stretched, you can get it to return to its original shape by applying heat. In addition, the surface of the glassy gels is highly adhesive, which is unusual for hard materials.”
