Platinum Fuel Cell Catalysts

Authors: George Rajna

Platinum has long been used as a catalyst to enable the oxidation reduction reaction at the center of fuel cell technology. [49] Titanium oxide (TiO2) nanofibers can have various applications, such as in catalyzers and filters. [48] Today, scientists report progress in making versions of these nanoparticles that could someday give built-in night vision to humans. [47] A new piece of a difficult puzzle-the nature of memory-fell into place this week with a hint at how brain cells change structure when they learn something. [46] Researchers at the University of Alberta have found an important protein in the cells of a deadly infectious parasite, opening the door to less harmful treatment for millions of people suffering from diseases like sleeping sickness in Africa and Chagas disease in South America. [45] The remarkable ability of a small Australian sea snail to produce a colourful purple compound to protect its eggs is proving even more remarkable for its potential in a new anti-cancer pharmaceutical. [44] Gene editing technology is a technology that eliminates the underlying causes of and treats diseases by removing specific genesor editing genes to restore their normal function. In particular, CRISPR gene editing technology is now commonly used for immunotherapy by correcting the genes of immune cells to induce them to attack cancer cells selectively. [43] Bioengineers and biophysicists from the have discovered that the toxicity of nanoparticles depends more on their size and the extent to which their surface area is charged than on their chemical composition. [42] That's now possible thanks to research by Rice University scientists who used the light-emitting properties of particular molecules to create a fluorescent nano-thermometer. [41]
