Silver, an element long favored by medicine for its antiseptic properties, turns out to be damaging to human fibroblasts when used in the dosages required to be effective. Furthermore, the presence of albumin weakens silver's ability to fight bacteria.
Using state-of-the-art visualization techniques, chemical engineers at ETH Zurich explore the complex inner life of porous catalysts. Their work will aid in the development of rational catalyst design, allowing promising laboratory leads to find their way into large-scale industrial production.
In a study that could lead to advances in the emerging fields of optical computing and nanomaterials, researchers at Missouri University of Science and Technology report that a new class of nanoscale slot waveguides pack 100 to 1,000 times more transverse optical force than conventional silicon slot waveguides.
Scientists succeeded in the identification of presence or absence of any of the spot jumps in DNA sequence by designing a method that enables the distinction of all eight possible forms of single nucleotide polymorphism (SNP).
Until now, no chip existed, on which both silicon and erbium-doped material were integrated. In her thesis, PhD candidate Laura Agazzi of the University of Twente demonstrates a working chip for the first time.
A team led by Oak Ridge National Laboratory's Ho Nyung Lee has discovered a strain relaxation phenomenon in cobaltites that has eluded researchers for decades and may lead to advances in fuel cells, magnetic sensors and a host of energy-related materials.
Using a microscopic optical sensor that can be batch-fabricated on a silicon chip at low cost, Researchers from the NIST Center for Nanoscale Science and Technology have measured the mechanical motion between two nanofabricated structures with a precision close to the fundamental limit imposed by quantum mechanics.
