A research team from the Northwestern University has found that one-dimensional materials such as individual gallium nitride nanowires demonstrate powerful piezoelectricity, a three-dimensional phenomenon caused by the application of mechanical stress.
Intertek Cantox, a company offering regulatory and scientific consulting services, has developed a novel method called the Nano Study Score method to support superior-quality nanotoxicology studies in order to assess the safety of nanomaterial- and nanotechnology-based products.
Scientists from the Purdue University, Melbourne University and University of New South Wales have fabricated the smallest silicon-based wire in the world, with a current-conducting capability equivalent to that of copper wires. The silicon wire has four-atom width and one-atom height.
Using quantum mechanical calculations, a research team at the University of Houston has demonstrated that a graphene sheet can be converted into a piezoelectric material by producing holes in a specific pattern onto it.
Researchers from the University of California at Berkeley and Rice University have discovered that when stress is applied, graphene does not rip apart randomly like paper but follows the least resistance path resulting in new edges that provide remarkable properties to the wonder material.
A research team led by Dr. Christian Russel from the Otto-Schott-Institute for Glass Chemistry, Friedrich Schiller University Jena, has developed a novel glass-ceramic material with a nanocrystalline structure, which can be used in dentistry applications thanks to its optical properties and superior strength.
Scientists have identified an improved approach for removing major greenhouse gas such as carbon dioxide that causes global warming from the air containing moisture and smokestacks. The report of this new process in achieving increased CO2 removal capacity from the atmosphere is published in the Journal of the American Chemical Society.
A research team led by Vincent Meunier from Rensselaer Polytechnic Institute has discovered the unique properties of graphene nanowiggles, a new type of graphene material, by utilizing the capabilities of the Rensselaer Center for Nanotechnology Innovations (CCNI).
Professors Kostya Novoselov and Andre Geim, who received the Nobel Prize for Physics for their innovative research works to study graphene and its superior properties, have been awarded knighthoods. They have been knighted for ‘Services to Science.’
Graphene has the tendency to stack together to form graphite. A method developed by scientists from the University of Cambridge, DSO National Laboratories and the National University of Singapore (NUS) prevents graphene sheets from re-stacking by bonding alkyl surface chains on them, while maintaining the characteristics of their nano-graphene pockets.
