Researchers at POSTECH, led by Professor Kyu-Young Park, have developed a new single-crystal synthesis technology for nickel-based cathode materials in electric vehicle batteries, demonstrating significantly enhanced lifespan and durability. Their work, published in ACS Materials & Interfaces, highlights the critical temperature needed for synthesizing robust single crystals, contributing to more durable and efficient batteries. =================================================================== POSTECH researchers have advanced electric vehicle battery technology by developing a method to synthesize durable single-crystal cathode materials, extending battery life and efficiency. Could high-temperature single crystals enable electric vehicles capable of traveling up to one million kilometers? A team from Pohang University of Science...

A senior NASA scientist pleaded guilty on Jan. 13 to lying about his ties to a Chinese-backed program designed to harvest talents from the West and transfer intellectual property to China, the Justice Department announced. Meyya Meyyappan, 66, joined NASA (National Aeronautics and Space Administration) in 1996 and has been the chief scientist for exploration technology at NASA’s Ames Research Center in California’s Silicon Valley since 2006. He was charged with one count of making false statements and could face a maximum five-year prison sentence and up to $250,000 fine if convicted, according to a Justice Department press release. The...

ABOARD THE USNS SALVOR, Yellow Sea — Clear skies and a billowing sea Saturday were not telling of what was beneath the surface: brutally strong currents, frigid temperatures, and water so murky that divers would barely be able see in front of them if they had to go in. Those conditions, U.S. Navy divers and officials aboard this rescue and salvage ship said, are expected to persist and will make salvaging the wreckage of the South Korean patrol ship Cheonan that mysteriously sank more than a week ago unusually difficult. “This is a very challenging dive scene,” said Capt. Charlie...
