Scientists have demonstrated how tiny magnetization patterns known as skyrmions can be written into a ferromagnetic material faster than previously thought possible. • Email to a friend • Physicists have discovered a much faster approach to create a pattern of spins in a magnet. This 'shortcut' opens a new chapter in topology research. Interestingly, this discovery also offers an additional method to achieve more efficient magnetic data storage. • Email to a friend • Using these new particles, researchers could develop treatments for heart disease and other conditions. • Email to a friend • Spinach, when converted from its leafy, edible form into carbon nanosheets, acts as a catalyst for an oxygen reduction reaction in fuel cells and metal-air batteries. • Email to a friend • A study of a solar-energy material with a bright future revealed a way to slow phonons, the waves that transport heat. The discovery could improve novel hot-carrier solar cells, which convert sunlight to electricity more efficiently than conventional solar cells by harnessing photogenerated charge carriers before they lose energy to heat. • Email to a friend • Interface engineered 2D titanium carbide MXene film serves as efficient flexible electrodes for light-emitting diodes. • Email to a friend • Researchers have developed a method for concentrating and releasing drugs in the brain with pinpoint accuracy. This could make it possible in the future to deliver psychiatric and cancer drugs and other medications only to those regions of the brain where this is medically desirable. • Email to a friend • Researchers have developed a biocompatible microswimmer made of carbon nitride, which they can propel forward through light. The particle can also store solar energy similar to miniature solar cells equipped with batteries, and can thus also swim in the dark using the stored energy. • Email to a friend • Researchers study a novel strategy to synthesize low bandgap polymers on a gold surface taking advantage of their molecular vibrations. The work combines the chemical synthesis with STM and AFM studies of the electronic properties of bisanthene polymers, whose synthesis is not feasible by conventional methods. • Email to a friend • Two-dimensional crumpled nanostructure with 40% higher efficiency. • Email to a friend • |
