New technology using silver may hold key to electronics advances
(Oregon State University) Engineers have invented a way to fabricate silver, a highly conductive metal, for printed electronics that are produced at room temperature. There may be broad applications in microelectronics, sensors, energy devices, low emissivity coatings and even transparent displays.

Launch of first European nanomedicine characterization lab
(Swiss Federal Laboratories for Materials Science and Technology (EMPA)) Empa, the Swiss Federal Laboratories for Materials Science and Technology, is part of the collaborative 'European Nanomedicine Characterization Laboratory,' a European project funded by the EU framework program 'Horizon 2020.' Its goal is to reach a level of international excellence in nanomedicine characterization for diseases like cancer, diabetes, inflammatory diseases or infections. This competence will be made accessible to all organizations developing candidate nanomedicines prior to their submission to regulatory agencies to get approval for clinical trials and, later on, for marketing authorization.

Nanospiked bacteria are the brightest hard X-ray emitters
(Tata Institute of Fundamental Research) In a scientific breakthrough, researchers at the Tata Institute of Fundamental Research, Mumbai and Institute for Plasma Research, Gandhi Nagar have fashioned bacteria to emit intense, hard X-ray radiation. Published in Optics Express this month, they show that irradiating a glass slide coated with nanoparticle doped bacteria, turns the cellular material into hot, dense plasma, making this a useful table top X-ray source with several potential applications.

Creating a stopwatch for volcanic eruptions
(Arizona State University) According to new research at Arizona State University, there may be a way to predict when Yellowstone volcano will erupt again.

NIST 'how-to' website documents procedures for nano-EHS research and testing
(National Institute of Standards and Technology (NIST)) As engineered nanomaterials increasingly find their way into commercial products, researchers who study the potential environmental or health impacts of those materials face a growing challenge to accurately measure and characterize them. These challenges affect measurements of basic chemical and physical properties as well as toxicology assessments. To help nano-EHS (Environment, Health and Safety) researchers navigate the often complex measurement issues, NIST has launched a new website devoted to validated laboratory protocols for nano-EHS studies.

Ultra-stable JILA microscopy technique tracks tiny objects for hours
(National Institute of Standards and Technology (NIST)) JILA researchers have designed a microscope instrument so stable that it can accurately measure the 3-D movement of individual molecules over many hours -- hundreds of times longer than the current limit measured in seconds. The technology was designed to track the machinery of biological cells, down to the tiniest bits of DNA, a single 'base pair' of nucleotides among the 3 billion of these chemical units in human genes. But the instrument could be useful well beyond biology, biochemistry and biophysics, perhaps in manufacturing.

Drexel's microscale 'Transformers' are joining forces to break through blocked arteries
(Drexel University) Swarms of microscopic, magnetic, robotic beads could be scrubbing in next to the world's top vascular surgeons -- all taking aim at blocked arteries. These microrobots, which look and move like corkscrew-shaped bacteria, are being developed by mechanical engineers at Drexel University as a part of a surgical toolkit being assembled by the Daegu Gyeongbuk Institute of Science and Technology in South Korea.

Effective conversion of methane by a new copper zeolite
(Technical University of Munich (TUM)) A new bio-inspired zeolite catalyst, developed by an international team with researchers from Technische Universitt Mnchen, Eindhoven University of Technology and University of Amsterdam, might pave the way to small scale 'gas-to-liquid' technologies converting natural gas to fuels and starting materials for the chemical industry. Investigating the mechanism of the selective oxidation of methane to methanol they identified a trinuclear copper-oxo-cluster as the active center inside the zeolite micropores.

A single molecule in the building blocks of life
(Aarhus University) The world is built up of molecules that join together and form different building blocks. New software makes it easier to zoom right in to the individual molecule.

Chitosan-coated, chemotherapy-packed nanoparticles may target cancer stem cells
(Ohio State University Wexner Medical Center) Nanoparticles packed with a clinically used chemotherapy drug and coated with an oligosaccharide derived from the carapace of crustaceans might effectively target and kill cancer stem-like cells, according to a recent study led by researchers at The Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.
