Nanoparticles are used in many commercial products catalysts to cosmetics. A review published today in the Science and Technology of Advanced Materials by researchers in Sweden and Spain describes recent work on the 3 main nanoparticles used in photocatalytic, UV-blocking and sunscreens.
The College of Science and Engineering, University of Glasgow is pleased to announce that funded places are available to students domiciled in Scotland and the EU, for its MSc Nanoscience and Nanotechnology programme within the School of Engineering, commencing September 2013.
Scientists at Argonne National Laboratory have recently discovered that they could substitute one-atom-thick graphene layers for oil-based lubricants on sliding steel surfaces, enabling a dramatic reduction in the amount of wear and friction.
Researchers succeeded in measuring the volumetric expansion of single particles of silicon, which is a negative electrode material for lithium ion batteries, accompanying the charging reaction, and demonstrated the importance of electrode design from the viewpoint of volumetric energy density based on this finding.
Researchers have developed a new set of metrics for analyzing data acquired via small angle scattering (SAS) experiments with X-rays (SAXS) or neutrons (SANS). Among other advantages, this will reduce the time required to collect data by up to 20 times.
Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.
Scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first time, the imaging of nanoscale processes, such as the engulfment of nanoparticles into cells.
The energy sector is currently facing important technological challenges, not only to incorporate renewable energies but also to modify and make the entire energy production and distribution system more efficient. Nanotechnology developments offer unique solutions which are applicable to the generation, distribution, transportation and storage of energy and the numerous technological developments in this field are numerous.
Researchers have been able to improve the efficiency of solar cells by coating the cell surface with extremely small nanoscale structures. The new technology has been shown to nearly eliminate the reflection losses of solar radiation.
Researchers at Tyndall National Institute at UCC in Cork, Ireland are leading an international project in advanced nanoelectronics which is aimed at maintaining Europe's position as a world leader in innovative automotive power electronic systems for both conventional and electric cars.
