Despite its current elusiveness in many parts of the northern hemisphere, no-one can boycott the sun! Harnessing nanotechnology development for sustainable energy enables us to focus on energy security and move away from our dependence on an ever-depleting supply of fossil fuels from regions that are often destabilised through ownership of these resources.
One of the rarest metals on Earth may be an excellent option for enabling future flash memory chips to continue increasing in speed and density, according to a group of researchers in Taiwan, who describe incorporating nanocrystals of iridium into critical components of flash memory.
Manufacturing semiconductors for electronics involves etching small features onto wafers using lasers, a process that is limited by the wavelength of the light itself. The development of a new, intense 13.5-nm light source will resolve this issue by reducing the feature size by an order of magnitude or so.
Moving a step closer toward quantum computing, a research team in the Netherlands recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere 7,000 cubic nanometers.
SCF-III, in this series will provide a continued forum for discussions in this rapidly growing field of syntactic foams and composite foams. Syntactic foams and rigid polymer, metal, and ceramic foams containing a reinforcing and/or functional phase are the intended focus of this conference.
Although engineering has long played a key role in developing technology for diagnosing and treating human disease, it has only recently started to have an impact on understanding the cellular and molecular basis of disease. In the past decade or so, engineers have started making major contributions to understanding diseases such as malaria, hereditary blood diseases and cancer, according to Subra Suresh, former dean of MIT's School of Engineering.
A research group headed by MANA Scientist Dr. Minoru Osada and Principal Investigator Dr. Takayoshi Sasaki of the International Center for Materials Nanoarchitectonics (MANA) at the National Institute for Materials Science (NIMS) successfully developed a novel nanoferroelectric by a solution-based bottom-up nanotechnology.
Bioengineers at the UCLA Henry Samueli School of Engineering and Applied Science have been exploring a unique phenomenon whereby randomly dispersed microparticles self-assemble into a highly organized structure as they flow through microscale channels.
Researchers with Lawrence Berkeley National Laboratory have been able to fabricate nanochannels that are only two nanometers in size, using standard semiconductor manufacturing processes. Already they've used these nanochannels to discover that fluid mechanics for passages this small are significantly different not only from bulk-sized channels, but even from channels that are merely 10 nanometers in size.
You can touch a functioning light bulb and know right away that it's hot. Ouch! But you can't touch a single molecule and get the same feedback. Rice University researchers say they have the next best thing -- a way to determine the temperature of a molecule or flowing electrons by using Raman spectroscopy combined with an optical antenna.
Dreidimensionale Gerueste, auf denen Zellen sich ansiedeln und zu Geweben oder Organen heranwachsen koennen, sind in der regenerativen Medizin begehrt. Materialwissenschaftler der Uni Wuerzburg haben dafuer erfolgreich neue Fasern mit ganz besonderen Eigenschaften entwickelt.
