EV battery recycling key to future lithium supplies

Lightweight, powerful lithium-ion batteries are crucial for the transition to electric vehicles, and global demand for lithium is set to grow rapidly over the next 25 years. A new analysis from the University of California, Davis, published May 29 in Nature Sustainability, looks at how new mining operations and battery recycling could meet that demand….

Breakthrough magnet design could transform MRI and magnetic levitation

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for generating homogeneous magnetic fields using permanent magnets. Their method outperforms the classical Halbach arrangement — which is optimal only for infinitely long and therefore unrealizable magnets —…
