Using a combination of sophisticated computer modeling and advanced materials analysis techniques at synchrotron laboratories, a research team has demonstrated how some relatively simple processing flaws can seriously degrade the otherwise near-magical electronic properties of graphene.
The young company HeiQ helps with oil disasters. Fleece mats treated with a special impregnating technique can soak up huge amounts of oil and thus protect entire stretches of coast from contamination.
It's super strong, it's green and it's providing new opportunities for business in Alberta. It's called nanocrystalline cellulose (NCC) and Alberta is about to become a leader in its production and study. A new Edmonton-based pilot facility will be the first in Canada to produce the quality of NCC that researchers need to fully explore all its potential applications.
Joint Quantum Institute researchers led by Christopher Monroe, with theoreticians from University of Michigan, University of Auckland, and Georgetown University have observed a quantum ferromagnet using a nine ion crystal, in an atom-by-atom approach to quantum simulations of magnetism.
By pairing an award-winning remote-detection version of NMR/MRI technology with a unique version of chromatography specifically designed for microfluidic chips, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory have opened the door to a portable system for highly sensitive multi-dimensional chemical analysis that would be impractical if not impossible with conventional technologies.
Showcasing new tools for widespread development of quantum circuits made of mechanical parts, scientists from the National Institute of Standards and Technology (NIST) have demonstrated a flexible, broadly usable technique for steadily calming the vibrations of an engineered mechanical object down to the quantum 'ground state', the lowest possible energy level.
An automatic and portable detector that takes just fifteen minutes to analyze a sample suspected of contamination with anthrax is being developed by US researchers. The technology amplifies any anthrax DNA present in the sample and can reveal the presence of just 40 microscopic cells of the deadly bacteria Bacillus anthracis.
Researchers at the Georgia Institute of Technology have designed a multiple-compartment gel capsule that could be used to simultaneously deliver drugs of different types. The researchers used a simple "one-pot" method to prepare the hydrogel capsules, which measure less than one micron.
To the human eye, carbon nanotubes usually appear as a black powder. They can hardly be forced to emit light, as they are excellent electrical conductors and capture the energy from other luminescent chemical species placed nearby. The researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw contributed recently to the development of a relatively simple method allowing the nanotubes exposed to UV to emit red light.
Many cell types in higher organisms are capable of implementing directed motion in response to the presence of certain chemical attractants in their vicinity. A team at the Center for NanoScience (CeNS) at Ludwig-Maximilians-Universitaet (LMU) Muenchen has developed a novel technique to expose an ensemble of living cells to rapidly varying concentrations of chemoattractants.
The U.S. Environmental Protection Agency (EPA), as part of its Science to Achieve Results (STAR) program, is seeking applications proposing to conduct research necessary to identify, develop and demonstrate novel and innovative treatment technologies and approaches for small public drinking water systems.
The making of three-dimensional nanostructured materials - ones that have distinctive shapes and structures at scales of a few billionths of a meter - has become a fertile area of research, producing materials that are useful for electronics, photonics, phononics and biomedical devices. But the methods of making such materials have been limited in the 3-D complexity they can produce. Now, an MIT team has found a way to produce more complicated structures by using a blend of current "top-down" and "bottom-up" approaches.
