Researchers from India and Singapore report a crystalline membrane made from polyoxometalate clusters whose intrinsic openings are about 1 nanometer wide, enabling unusually sharp molecular separations that could help lower energy use in some industrial purification and water-reuse steps.
A team at Rice University has invented an eco-friendly material that rapidly captures and destroys PFAS, known as forever chemicals, in water sources. The technology outperforms existing methods by capturing pollutants thousands of times more efficiently and regenerating for reuse. Published in Advanced Materials, the breakthrough addresses a persistent global pollution challenge.

Researchers have developed a simple, hand-cranked jar that uses nanoparticles to remove pathogens from drinking water in seconds, offering a solution for off-grid areas. The device activates through manual stirring, generating chemicals that destroy microbes without needing electricity or sunlight. It targets parasites, bacteria, viruses, and fungi, achieving high reduction rates in tests.
