Hybrid nanocomposite material as gold-leaf substitute

A team of researchers has created a hybrid material out of gold and milk proteins that looks like a wafer-thin gold leaf. Thanks to its properties, it could be used in a vast range of applications from gastronomy to the jewellery industry.

Nanocatalyst material for fuel cells saves 90 percent platinum

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.

Nntioxidant with a long shelf life

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.

Physiker nutzen Nanodiamanten als Lichtquelle

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.

Combining X-rays and microscopes for getting the atomic-level fingerprint of a material

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.

Nanotechnology helping to recover more oil

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 science of sculpture, nano-style

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.

Real-world invisibility cloak makes cat and fish disappear (w/videos)

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.

Nanotechnology-based sensor identifies scent of melanoma

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.
