The new technique may reduce drug side effects, and in the long term, ion pumps may help patients with symptoms of neurological diseases for which effective treatments are not available. The results have been published in Science Advances. Approximate...

Credit: Jin Yang Scientists in China and Sweden have determined that a pinch of capsaicin, the chemical compound that gives chili peppers their spicy sting, may be a secret ingredient for more stable and efficient perovskite solar cells. The research, published January 13 in the journal Joule, determined that sprinkling capsaicin into the precursor of methylammonium lead triiodide (MAPbI3) perovskite during the manufacturing process led to a greater abundance of electrons (instead of empty placeholders) to conduct current at the semiconductor's surface. The addition resulted in polycrystalli...

Applied Material & Interfaces. “We set out to fill the HMPC matrix with bacterial cellulose nanocrystals in order to enhance its properties. We also wanted to create greener protocols for the development of novel composites, from the material itself to its origin, so we included the reuse of industrial waste in the project,” said Márcia Regina de Moura Aouada, a co-author of the article. Aouada has a PhD in chemistry from UNESP, where she teaches and is a researcher at the Center for Development of Functional Materials ( CDMF), one of the Research, Innovation and Dissemination Centers (...
