A team of scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, and SLAC National Accelerator Laboratory say they've found a way to make a battery cathode with a hierarchical structure where the reactive material is abundant yet protected--key points for high capacity and long battery life.
Three scientists at the University of Washington have proposed a way to speed up common bioassays. Their solution, reminiscent of the magic behind washing machines, could reduce wait times to a fraction of what they once were. Biological assays that once took hours could instead take minutes.
For the first time, researchers tailored the electronic properties of nanoribbons using a new “bottom-up” method that precisely controls and modulates the atomic-scale width within a single nanoribbon.
A team at the Weizmann Institute of Science found that when spherical nanoparticles self-assembled into a cluster, empty spaces – “flasks” – formed between them, as between oranges packed in a case. They were able to produce a range of chemical reactions in the flasks that were 100 times faster than in solution. The many potential applications include drug delivery.
ROLLA, Mo. — A Missouri University of Science and Technology researcher and his colleagues have created a lightweight but very strong structural metal that could improve energy efficiency in aerospace, automobile, defense, mobile electronics and biomedical applications.
Researchers at the University of Minnesota and BioNano Genomics have improved a nanochannel-based form of mapping by using dynamic time-series data to measure the probability distribution, or how much genetic material separates two labels, based on whether the strands are stretched or compressed. They detail their work this week in Biomicrofluidics.
From creating the tiniest drops of primordial particle soup to devising new ways to improve batteries, catalysts, superconductors, and more, scientists at the U.S. Department of Energy's Brookhaven National Laboratory pushed the boundaries of discovery in 2015.
Scientists have proposed a metasurface for the anomalous scattering of visible light.
Researchers at MINAO, a joint lab between The French Aerospace Lab in Palaiseau and the Laboratoire de Photonique et de Nanostructures in Marcoussis, have recently demonstrated metamaterial resonators that allow emission in the infrared to be tuned through the geometry of the resonator.
Researchers have demonstrated a new process for rapidly fabricating complex three-dimensional nanostructures from a variety of materials, including metals. The new technique uses nanoelectrospray to provide a continuous supply of liquid precursor, which can include metal ions that are converted to high-purity metal by a focused electron beam.
State-of-the-art atomic force microscopes (AFMs) are designed to capture images of structures as small as a fraction of a nanometer -- a million times smaller than the width of a human hair. In recent years, AFMs have produced desktop-worthy close-ups of atom-sized structures, from single strands of DNA to individual hydrogen bonds between molecules.
A research team including NIBIB-funded scientists have developed a sunscreen that encapsulates the UV-blocking compounds inside bio-adhesive nanoparticles, which adhere to the skin well, but do not penetrate beyond the skin’s surface. These properties resulted in highly effective UV protection in a mouse model, without the adverse effects observed with commercial sunscreens, including penetration into the bloodstream and generation of reactive oxygen species, which can damage DNA and lead to cancer.
An optical device at nanoscale which allows light to pass in only one direction has been developed at TU Wien (Vienna). It consists of alkali atoms which are coupled to ultrathin glass fibres.
The University of Chicago’s Department of Chemistry and Institute of Molecular Engineering have jointly appointed Jiwoong Park as a faculty member. He will start the position on July 1, 2016.
Nano implies small—and that’s great for use in medical devices, beauty products and smartphones—but it’s also a problem. All these tiny particles get into our water and are difficult to remove. Now, researchers Yoke Khin Yap and Dongyang Zhang have a novel and very simple way to take the nanomaterials out.
Advances in nanolensing would make possible extremely high-resolution imaging or biological sensing.
Friction hampers the movement of all mechanical parts, including engines for transportation. Scientists built a system with virtually no friction. The system wraps graphene flakes around nanodiamonds that then roll between a diamond-like carbon-surface and graphene on silica.
Never mind the ABCs. Rice University scientists interested in nanotubes are studying their XYΩs. Carbon nanotubes grown in a furnace aren't always straight. Sometimes they curve and kink, and sometimes they branch off in several directions. The Rice researchers realized they now had the tools available to examine just how tough those branches are.
Alesha Harris has three degrees in chemistry and has taught the subject in her home state of Texas. Although her graduate work was in nanoparticles—materials just a billionth of a meter in size—she joined the U.S. Department of Energy’s Brookhaven National Laboratory as an Alliance for Graduate Education and the Professoriate–Transformation (AGEP-T) postdoc working with Minfang Yeh, who leads the neutrino and nuclear chemistry group.
Four researchers from the Department of Energy's Oak Ridge National Laboratory have been elected fellows of the American Physical Society (APS), one of the nation's top professional organizations for scientists.
