nanotech moving forward

“ In fact, if gold is created in small enough chunks, it turns red, blue, yellow and other colors.....”

“ Kiely and Harmer have learned that they can tailor the properties of their nanoparticles assemblies by varying the size and elemental composition of the particles.”

“ One such reaction is the conversion of carbon-monoxide (CO) to carbon-dioxide (CO2). Nanogold catalyzes this at room temperature and with 100-percent efficiency. A potential application is to aid firefighters, who now wear protective masks containing copper-manganese-oxide. That material's effectiveness at getting rid of CO, however, lasts only 15 minutes, while nanogold protects for several hours.”

ab: I found this article mildly interesting on a level I could get some idea of what was being attempted (I know nothing about this stuff!)

“Scientists have demonstrated, for the first time, that transistors made from single-walled carbon nanotubes can operate at extremely fast microwave frequencies, opening up the potential for better cell phones and much faster computers, perhaps as much as 1,000 times faster.”
