A new electrode design for lithium-ion batteries has been shown to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles.
For years, scientists have been pursuing 'artificial leaf' technology, a green approach to making hydrogen fuel. Now, one team reports progress toward a stand-alone system that lends itself to large-scale, low-cost production.
Though it is less than 100 nanometers thick, the bond can withstand pressure up to 2 megapascals (almost 300 pounds per square inch), and its drift, or how much it shifts over time, is on the order of less than 3 trillionths of a meter per hour.
Scientists have been successful in producing highly specific nanoparticles. Depending on the bound dye the particles are guided to the liver or to the kidney and deliver their payload of active ingredients directly to the targeted tissue.
