“Our microwave induction heating technology enables fast and easy preparation of hard carbon, which I believe will contribute to the commercialization of sodium-ion batteries,” said Dr. Daeho Kim.


Can sodium-ion batteries be improved to exceed the efficiency and longevity of traditional lithium-ion batteries? This is what a recent study published in Chemical Engineering Journal hopes to address as a team of researchers from South Korea investigated how microwave induction heating can produce sufficient carbon anodes used in sodium-ion batteries. This study holds the potential to help researchers and engineers better understand how to develop and produce efficient sodium-ion batteries, which have demonstrated greater abundancy and stability.

“Due to recent electric vehicle fires, there has been growing interest in sodium-ion batteries that are safer and function well in colder conditions. However, the carbonization process for anodes has been a significant disadvantage in terms of energy efficiency and cost,” said Dr. Jong Hwan Park, who is from the Korea Electrotechnology Research Institute (KERI) and a co-author on the study.

For the study, the KERI-led researchers improved upon existing sodium-ion batteries by using microwave technology, which involves heating carbon nanotubes using a microwave magnetic field, resulting in temperature exceeding 1,400 degrees Celsius (2,550 degrees Fahrenheit) in only 30 seconds. This breakthrough improves upon traditional methods for procuring carbon anodes, which typically require lengthy amounts of time to reach just 1,000 degrees Celsius (1,800 degrees Fahrenheit).

SpaceX undertook a planetary defense mission on behalf of the European Space Agency (ESA) on Monday, aiming to provide scientists with tools to prevent future catastrophic cosmic impacts.

The ESA’s Hera planetary defense mission builds on NASA’s 2022 Double Asteroid Redirection Test (DART) mission and will analyze its effects, allowing scientists and engineers to gain a more comprehensive understanding for use in real-world emergencies.

“What the FBI uncovered in this case is essentially a new twist to old-school financial crime,” Jodi Cohen, the special agent in charge of the FBI’s Boston division, said in a statement. “What we uncovered has resulted in charges against the leadership of four cryptocurrency companies, and four crypto ‘market makers’ and their employees who are accused of spearheading a sophisticated trading scheme that allegedly bilked honest investors out of millions of dollars.”

Liu Zhou, a “market maker” working with MyTrade MM, allegedly told promoters of NexFundAI that MyTrade MM was better than its competitors because they “control the pump and dump” allowing them to “do inside trading easily.”

An FBI spokesperson told CoinDesk that there was limited trading activity on the coin but didn’t share additional information. On a Wednesday press call, Joshua Levy, the acting US attorney for the District of Massachusetts, said trading on the token was disabled, according to CoinDesk.

In the quantum world, materials called “altermagnets” behave in unique ways that could pave the way for new technologies.


This unique magnetism makes altermagnets highly promising for the development of new spintronic and . It also opens new possibilities for the study of topological materials (i.e., systems with unique electronic properties originating from their electronic structure’s topology).

Researchers at Stony Brook University carried out a study aimed at better understanding the nonlinear response of planar altermagnets. Their paper, published in Physical Review Letters, reports the observation of a non-linear response in these materials derived from their quantum geometry.

“Recently, two experiments have confirmed the predicted role of quantum geometry in the second-order response of the conventional PT-symmetric antiferromagnets,” Sayed Ali Akbar Ghorashi, co-author of the paper, told Phys.org.
