Paper bags and cardboard boxes normally headed for the trash were carbonized into anodes for lithium-ion batteries, and the resulting electrodes survived 1,200 charge cycles — roughly twice the durability of anodes used in current phone batteries
1+ day, 17+ hour ago (441+ words) By Science Blog Editorial Team Published September 12, 2026 · How we edit A paper bag that carried someone’s lunch on Tuesday has a plausible future inside a phone. Researchers at NTU Singapore have worked out how to bake kraft paper, the brown…...
Every time a raindrop sticks and slips as it runs down a surface, it can generate a tiny electrical charge. In March 2025, RMIT and University of Melbourne researchers discovered a previously overlooked charging mechanism that can produce about 10 times more charge than the familiar wet-to-dry process.
3+ week, 6+ day ago (1291+ words) A water drop can create an extra burst of charge when its advancing edge catches on a microscopic defect and tears free. The strongest runs approached ten times the study's ordinary wet-to-dry signal, but the real insight is how surface…...
