In a new study, Brown University engineers report that when they used selenium nanoparticles to coat polycarbonate, the material of catheters and endotracheal tubes, the results were significant reductions in cultured populations of Staphylococcus aureus bacteria, sometimes by as much as 90 percent.
Researchers have introduced a particularly clever biosensor concept: print on one side of the paper, fold it up origami-style, laminate it, and the test is ready. Test evaluation requires only a voltmeter.
Graphen ist das wohl dŁnnste Netz der Welt - und zeichnet sich doch durch seine Festigkeit aus. Eine neue Studie zeigt, dass dieses zweidimensionale Gitter aus Kohlenstoff-Atomen sogar Licht gefangen nehmen kann.
Scientists are reporting development and successful testing of a fabric coating that would give new meaning to the phrase "stain-resistant" - a coating that would take an active role in sloughing off grease, dirt, strong acids and other gunk.
Wall-climbing robots, bioadhesives or other sticky substances can benefit greatly from a recent discovery about the self-cleaning and reuse abilities of a gecko's foot hair by a University of Akron graduate student-researcher and his partners.
An international team of scientists performing angle-resolved photoemission spectroscopy (ARPES) experiments at ALS Beamline 7.0.1 have found that composite particles called plasmarons play a vital role in determining graphene's properties.
Scientists visualize the trapping and confinement of light on graphene, making a sheet of carbon atoms the most promising candidate for optical information processing on the nano-scale, optical detection, and ultrafast optoelectronics.
Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, and the Interdisciplinary Research Institute in Lille developed a low cost method for manufacturing multilayered graphene sheets. The new method does not require any specialized equipment and can be implemented in any laboratory.
New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA's double helix. This finding has ramifications for gene therapy research and the emerging field of DNA-based electronics.
A team led by SLAC Ph.D. candidate Sebastian Schorb found that the x-ray damage process in nanometer-sized clusters of atoms is slower than expected from previous studies of atoms and simple molecules.
An interdisciplinary team of researchers from Drexel University have reported the development of a new technology for grid-scale energy storage which could provide a fast, efficient method for storing energy on the electrical grid. This new technology, dubbed the "electrochemical flow capacitor", stores energy in the same way as a supercapacitor, but is much less costly to scale up for large, industrial applications.
