An ionic liquid and controlled electricity can pull critical metals from coal ash, offering a potential domestic supply route for materials essential to advanced electronics. Imagine a material that once drifted onto rooftops as a gritty nuisance now helping power the motors in electric cars or the magnets in wind turbines. Researchers at Georgia Tech have developed a promising way to pull valuable rare earth elements from the massive piles of coal fly ash left over from power plants. Their a

Touch the back of a laptop, and the warmth you feel is energy that has already been paid for, processed by chips, and then dissipated as heat. The work by Toshimasa Fujisawa and colleagues, reported in Communications Physics as “Efficient heat-energy conversion from a non-thermal Tomonaga-Luttinger liquid” and summarized in the TechXplore piece “A new approach to energy harvesting opened up by the quantum world,” asks a simple but radical question: what if that waste heat could be turned back i
