Biointegrated Batteries Turn Energy Storage Materials into Active Therapeutic Devices
2+ hour, 20+ min ago (148+ words) From flexible electrodes to biodegradable architectures, researchers are redesigning battery materials so that electrochemical reactions can do far more than supply power. Electrical stimulation can support wound healing, nerve regeneration, and bone repair. It can guide cell migration, promote Schwann-cell…...
Spent Lithium-Ion Batteries Transformed into Powerful Catalysts That
30+ min ago (75+ words) Every year, hundreds of millions of lithium-ion batteries reach the end of their working lives, and most of the valuable materials locked inside them are never recovered. At the same time, factories, paint shops and refineries continue to pump volatile…...
Palm Waste Biochar Supercharges Zinc Oxide Nanoparticles for Greener
35+ min ago (614+ words) Scientists in Nigeria have transformed an unlikely piece of agricultural trash—the male inflorescence fingers of the oil palm, routinely discarded by palm-wine tappers—into a sustainable doping agent that measurably improves the optoelectronic performance of zinc oxide nanoparticles....
Prussian Blue Meets Manganese Dioxide in Flexible Supercapacitor
1+ hour, 36+ min ago (596+ words) Wearable electronics have long been held back by one stubborn problem: batteries are rigid, heavy, and occasionally unsafe when bent, sweat on, or stitched into clothing. A research team at Isfahan University of Technology in Iran now reports a deceptively…...
Nickel Oxide Breakthrough Pushes Perovskite Solar Modules Toward Commercial
1+ hour, 42+ min ago (589+ words) Perovskite solar cells have long dazzled laboratory audiences with efficiencies that keep climbing year after year, yet the technology has stubbornly struggled to translate those record numbers into large-area modules that can be manufactured reliably at scale....
