L. Keith Woo is searching for cleaner, greener chemical reactions. Woo, an Iowa State University professor of chemistry and an associate of the U.S. Department of Energy's Ames Laboratory, has studied catalysts and the chemical reactions they affect for more than 25 years. And these days, his focus is on green catalysis.
Circulating tumor cells, which play a crucial role in cancer metastasis, have been known to science for more than 100 years, and researchers have long endeavored to track and capture them. Now, a UCLA research team has developed an innovative device based on Velcro-like nanoscale technology to efficiently identify and "grab" these circulating tumor cells, or CTCs, in the blood.
Carbon nanotubes have a multitude of unusual properties which make them promising candidates for optoelectronic components. However, so far it has proven extremely difficult to analyze or influence their optic and electronic properties. A team of researchers has now succeeded in developing a measurement method allowing a time-based resolution of the so-called photocurrent in photodetectors with picosecond precision.
The 365,000-square-foot building, designed by Cambridge-based architectural firm Ellenzweig, stretches along Main Street between Ames and Vassar streets, and houses 27 faculty labs and about 630 researchers.
Costa Rica and Brazil took the first steps to reach a bilateral agreement that would allow both nations to mutual cooperation in the development of nanotechnology, the space industry and in other areas of mutual interest.
Although Dr. Moon Kim's zeal for nanotechnology springs in part from years of research into the structural characterization of advanced electronic materials, he doesn't see why kids shouldn't be exhilarated by the very small as well. Now he's taken two steps to help make that happen, writing a nanotechnology primer for kids and starting an internship program that brings them into his lab for weeks at a time.
One of the key problems of nano-scale optical devices is how to guide and propagate incident light effectively. SPP waveguide has a long propagating distance and can transmit in metal-dielectric interface. How to enhance the coupling and transmission of SPP has attracted researchers' attention.
National Universities Commission (NUC) has signed a Memorandum of Understanding (MOU) with the Institute for Lasers, Photonics, and Biophotonics (ILPB), United States of America for the development of an international joint research centre for nanomedicine in some Nigerian universities.
Precision measurement in the world of nanoparticles has now become a possibility, thanks to scientists at UC Santa Barbara. The UCSB research team has developed a new instrument capable of detecting individual nanoparticles with diameters as small as a few tens of nanometers.
A new microscope invented by scientists at Howard Hughes Medical Institute's Janelia Farm Research Campus will let researchers use an exquisitely thin sheet of light -- similar to that used in supermarket bar-code scanners -- to peer inside single living cells, revealing the three-dimensional shapes of cellular landmarks in unprecedented detail. The microscopy technique images at high speed, so researchers can create dazzling movies that make biological processes, such as cell division, come alive.
The ONAMI Safer Nanomaterials and Nanomanufacturing Initiative's (SNNI) 6th annual Greener Nano Conference (GN11) - Advancing Applications and Reducing Risk - will be hosted by Hewlett-Packard Company at its Cupertino, CA site on May 1-3, 2011.
