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.
An important milestone toward the realization of a large-scale quantum computer, and further demonstration of a new level of the quantum control of light, were accomplished by a team of scientists at UC Santa Barbara and in China and Japan.
Scientists have identified a complex chemical reaction responsible for the degradation of two paintings by Vincent van Gogh and other artists of the late 19th century. This discovery is a first step to understanding how to stop the bright yellow colours of van Gogh's most famous paintings from being covered by a brown shade, and fading over time.
Vikas Berry, assistant professor of chemical engineering, has received a National Science Foundation CAREER award for his work involving graphene, which could lead to improved electronics and optoelectronics.
Pure organic compounds that glow in jewel tones could potentially lead to cheaper, more efficient and flexible display screens, among other applications. University of Michigan researcher Jinsang Kim and his colleagues have developed a new class of material that shines with phosphorescence - a property that has previously been seen only in non-organic compounds or organometallics.
easyJet, the UK's largest airline, today announced that it is the first commercial airline to trial a revolutionary nanotechnology coating on its aircraft aimed at reducing drag and increasing fuel efficiency.
