Researchers have found that the microwave irradiation of natural graphite flakes before the oxidation step improved the efficiency of the oxidation process. This facile method provides a greater amount of GO compared with the original Hummers' method.
Jackets with built-in mobile phones, sports clothes that warn you when your heart rate gets too high, wallpaper with glowing patterns - these are not concepts from a science fiction movie, some of them are actually already available, and they may soon become commonplace.
What is a nanoengineer? It's a question nearly 20 seniors, who, this June, earned the first bachelor's degree in nanoengineering offered at the University of California, San Diego, have learned to answer as they tackle the questions and expectations of their parents and potential employers.
VTT Technical Research Centre of Finland is developing new techniques for the production of metallic nanoparticles. VTT's new production reactor, operating at atmospheric pressure, reduces the production costs of multicomponent particles. It enables the production of metallic nanomaterials, which are not yet commercially available, for research and product development needs.
Electronic components built from single molecules using chemical synthesis could pave the way for smaller, faster and more green and sustainable electronic devices. Now for the first time, a transistor made from just one molecular monolayer has been made to work where it really counts. On a computer chip.
Industrial palladium-copper catalysts change their structures before they get to work, already during the activation process. As a result, the reaction is catalysed by a catalyst that is different from the one originally prepared for it.
The smaller components become, the more difficult it is to create patterns in an economical and reproducible way, according to an interdisciplinary team of Penn State researchers who, using sound waves, can place nanowires in repeatable patterns for potential use in a variety of sensors, optoelectronics and nanoscale circuits.
