Faster recycling of metals from lithium-ion batteries

Rice University researchers report a faster, more energy-efficient way to recover key metals from spent lithium-ion batteries using water-based amino chloride solutions. A hydroxylammonium chloride (HACl) solution showed the best extraction performance in tests.

Diamond dust not suitable for stratospheric cooling

Researchers at Washington University studied detonation-made diamond dust for stratospheric aerosol injection. Simulations show carbon impurities and sp2 carbon cause absorption and reduce scattering, so these nanodiamonds are unlikely to cool the planet effectively.

Light-powered material cleans PFAS from water

Scientists created a new, metal-free material that uses light to break down many water pollutants, including PFAS. The hybrid surface combines two lightweight materials and worked well in flowing-water tests similar to treatment plants.
