Gem-Like Nanoparticles as Catalysts

Authors: George Rajna

A Northwestern University research team has developed a new method for making highly desirable catalysts from metal nanoparticles that could lead to better fuel cells, among other applications. [52] Valencia University (UV) researchers have modified the photoconductance of nanoparticles of tungsten oxide (WO3) in a controlled manner. [51] Scientists who study the nanoscale-with molecules and materials 10,000 smaller than a pinhead-need to be able to test the way that some molecules twist, known as their chirality, because mirror image molecules with the same structure can have very different properties. [50] In a recent study, researchers at the NASA Ames Research Center have demonstrated that nanoscale vacuum channel transistors can be fabricated on silicon carbide wafers. [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]
