Microbial communities associated with ferromanganese nodules and the surrounding sediments
Frontiers in Microbiology, 2013 The formation and maintenance of deep-sea ferromanganese/polymetallic nodules still remains a mystery 140 years after their discovery. The wealth of rare metals concentrated in these nodules has spurred global interest in exploring the mining potential ...

Rethinking Sustainable Batteries
Advanced Energy Materials, Volume 15, Issue 47, December 16, 2025.This perspective examines sustainability across the entire battery lifecycle, from mining and manufacturing to use and end of life. Twelve principles for ‘green’ batteries are outlined, and it is argued that joint industrial, academic, and policy efforts are essential to building a truly sustainable energy future. Abstract Batteries will play a pivotal
