Researchers at MIT and Northeastern have come up with a new system for monitoring biomedical indicators - such as levels of sodium or glucose in the blood - that could someday lead to implantable devices that would allow, for example, people with diabetes to check their blood sugar just by glancing at an area of skin.
Twenty-eleven is the year that regulation of nanotechnology will move from a hypothetical possibility to a real issue for companies in virtually every industry sector that are benefitting from the new science of nanotechnology. Such regulation will raise profound policy, business and legal issues, which will be examined at a conference on March 21 sponsored by the Sandra Day O'Connor College of Law at Arizona State University.
A Colorado State University professor has successfully turned a mineral compound into a material that can pass current through a nanoparticle network - an important discovery into more efficient, inexpensive solar cell materials.
Scientists are reporting development and successful lab tests of "killer paper," a material intended for use as a new food packaging material that helps preserve foods by fighting the bacteria that cause spoilage. The paper contains a coating of silver nanoparticles, which are powerful anti-bacterial agents.
Ulrich Kortz, Professor of Chemistry at Jacobs University, and his team report the synthesis of a novel, discrete noble metal-oxide, containing a record number of 22 palladium atoms, as well as two central copper ions. In addition to its high catalytic potential, this cluster compound also exhibits very unusual intramolecular magnetic interactions.
DVDs werden millionenfach produziert, bis vor kurzem waren die chemisch-physikalischen Schreibprozesse dahinter allerdings ein Raetsel. Einem internationalen Forscher-Team gelang nun an der Uni Graz mittels Roentgenstrahlung der Durchbruch. Die WissenschafterInnen fanden einen Weg, wie Oberflaechen mit ungeordneter Struktur atomar, also im Nanobereich, abgebildet werden koennen.
In case of the Bose-Einstein-Condensation gases consisting of ultra-cold atoms change into a collective quantum state where they all have the same features. This state and the associated features are very interesting, for example, for the production of new circuits where the condensed particles flow nearly unimpeded. The problem is that the condensation with atoms only takes place in case of extremely low temperatures, rendering practical use completely impossible. Now physicists succeeded in creating the lightest condensate from substantial particles which can in fact be used at some kelvin.
The magnetic exchange bias coupling between core and shell depends critically on the "frozen spins" that reside at the interface between the two different magnetic nanomaterials, according to users from Purdue University.
EU-funded scientists have invented a new way of creating atom thin nano-sheets from a wide variety of exotic layered materials with the potential to enable the next generation of electronic and energy storage technologies needed, for example, to power electric cars.
The Center of Innovation for Nanobiotechnology (COIN) today announced the launch of an information-rich, comprehensive nanobiotechnology information portal available to the public called NanoBioConnect. The objective of COIN's NanoBioConnect portal is to provide a trusted and valued compendium of nanobio- and nanomedicine-related business and technology intelligence, including information on relevant assets, resources, and people.
When it comes to making a solar cell from semiconductors, there are two major challenges. One is to extract as much energy out of the sunlight as possible so that ideally every single photon of light creates an electron-hole pair. The other is to get these electron-hole pairs to all migrate to the electrical contacts where they can do useful work rather than simply recombining somewhere in the middle of the cell.
