Recent progress in chalcogenide glass photonics has been driven by scientific and technological challenges in a variety of areas. These range from increased demand for bandwidth in optical communications, to the emergence of bio-health hazards associated with hazardous microorganisms that absorb at mid-infrared wavelengths, to defense applications that require bright mid-infrared sources.
Five new US, European and Japanese companies join A*STAR's Industrial Consortium On Nanoimprint (ICON) to engineer marine life-inspired anti-microbial surfaces for use on ships, lenses and even medical devices. Technology will also be seeded at 3 participating local polytechnics.
Research directed by Basar Bilgicer, assistant professor of chemical and biomolecular engineering and a member of the Advanced Diagnostics and Therapeutics initiative at the University of Notre Dame, could one day enable clinicians to deliver powerful chemotherapy drugs to tumors without deleterious side effects.
They might just be the smallest Christmas tree decorations ever. Tiny spherical particles of gold and silver that are more than 100 million times smaller than the gold and silver baubles used to decorate seasonal fir trees have been synthesized by researchers in Mexico and the US.
The purpose of the OECD Series on the Safety of Manufactured Nanomaterials is to provide up-to-date information on the diverse activities at OECD related to human health and environmental safety. The two most recent additions to the series have jsut been published.
Nanotechnology development is in its early phase and there is a growing debate on its potential benefits and risks. This report reviews literature on public opin-ion and NGO perspectives concerning nanotechnology.
Researchers from Iowa State University and the Ames Laboratory have developed a process capable of producing a thin and uniform light-absorbing layer on textured substrates that improves the efficiency of polymer solar cells by increasing light absorption.
