magnets

A team led by North Carolina State University has demonstrated that magnetizing patterned elastic polymer sheets turns their chaotic snapping behavior into repeatable, sequential unfolding, boosting kinetic energy absorption by 30 percent.

A new class of high-entropy boride magnets made from earth-abundant metals achieves magnetic properties approaching rare-earth levels, offering a potential path to breaking dependence on Chinese-controlled supply chains for EVs, wind turbines, and electronics.
