With the aid of state-of-the-art electron microscopy, the researchers discovered that the function of the nanometre-scale catalyst particles is decisively determined by their geometric shape and atomic structure. This discovery opens up new paths for further improving catalysts for energy conversion and storage.
Scientists from ETH Zurich have developed a nanomaterial that protects other molecules from oxidation. Unlike many such active substances in the past, the ETH-Zurich researchers' antioxidant has a long shelf life, which makes it just the ticket for industrial applications.
The European Technology Platform for Nanomedicine (ETPN) and the EU-funded consortium, Nanomed2020, have launched the first ever Nanomedicine Award to honor the best international nanomedicine innovation for 2013. Entries for nominations for the Award will be open from 6th June to 7th September 2013.
Moderne Kommunikationstechnologie basiert darauf, dass Lichtimpulse durch Glasfaserkabel übertragen werden. An die Stelle von Lichtimpulsen, die aus 'Bündeln' von Lichtteilchen bestehen, sollen in Zukunft einzelne Lichtteilchen als Informationsträger treten - was unter anderem eine vollständig abhörsichere Datenübertragung in der Quantenkommunikation ermöglicht.
By pairing the capabilities of X-ray analysis and extremely precise microscopy, scientists at Argonne National Laboratory have developed a way to simultaneously determine the physical structure and chemical makeup of materials at close to the atomic level. The research opens new routes to the next generation of materials for a wide assortment of energy-related applications.
When petroleum companies abandon an oil well, more than half the reservoir's oil is usually left behind as too difficult to recover. Now, however, much of the residual oil can be recovered with the help of nanoparticles and a simple law of physics.
The next breakthrough in highly efficient battery technologies and solar cells may very well be nanoscopic crystals of silicon assembled like skyscrapers on wafer-??scale substrates. An important route for growth of these nanoscale 'whiskers' - or nanowires - involves alloyed metal droplets. Moneesh Upmanyu has been using computational tools to understand the atomic-??scale interactions between these droplets and the growth of nanowires.
Researchers have demonstrated in experiment that by abandoning the phase preservation requirement it is possible to create invisibility cloaking for natural light in multiple observation angles. Such a cloak will act as a cloaking device operational on the ray optics approximation. It will disregard the fine effects of interference seen in wave optics but will offer good performance for hiding macroscopic objects much larger than the wavelength of light.
According to new research from the Monell Center and collaborating institutions, odors from human skin cells can be used to identify melanoma, the deadliest form of skin cancer. In addition to detecting a unique odor signature associated with melanoma cells, the researchers also demonstrated that a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells.
Cheaper clean-energy technologies could be made possible thanks to a new discovery. Researchers have found that an important chemical reaction that generates hydrogen from water is effectively triggered - or catalyzed - by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth.
At this week's VLSI 2013 Technology Symposium 2013 (Kyoto, Japan, June 11-13, 2013), imec presented important findings increasing the understanding into the stochastic nature of Resistive Random Access Memory (RRAM) operation. Imec's results are crucial steps forward to enable reliable implementation of the memory concept.
