UCI Physicists Exploring Use of Blu-Ray Disc Lasers to Kill COVID-19
IRVINE, Calif., May 21, 2020 — A team led by physicist Chris Barty of the University of California, Irvine is researching the use of diodes from Blu-ray digital videodisc devices as deep-ultraviolet laser photon sources to rapidly disinfect surfaces and indoor air. Barty, UCI Distinguished Professor of Physics and Astronomy, said that such UV-light sterilizers would be cheap compared to current medical- and scientific-grade systems and that it would be possible to deploy them almost anywhere. “If these
ERC Grant Furthers Study of Quantum Info Processing
VIENNA, Jan. 23, 2014 — A five-year, $2.7 million grant awarded by the European Research Council (ERC) will further the study of fiber-based quantum communications and information processing. Arno Rauschenbeutel, a professor at the Atomic Institute at Vienna University of...
Precise sensor made of hydrogels
WEST LAFAYETTE, Ind. – A new type of biological and chemical sensor made of thin stripes of hydrogel, a gelatinous material that expands and contracts depending upon the acidity of its environment, has been developed by researchers at Purdue University. The sensors,...
Nanotubes Create Atomic ‘Black Hole’
CAMBRIDGE, Mass., April 7, 2010 — Carbon nanotubes, long touted for applications in materials and electronics, may also be the stuff of atomic-scale black holes. Physicists at Harvard University have found that a high-voltage nanotube can cause cold atoms to spiral inward under...
QED Implements ASI Metrology System
ROCHESTER, N.Y., March 4, 2010 – QED Technologies, an exclusive provider of magnetorheological finishing (MRF) and subaperture stitching interferometry (SSI), has announced the implementation of one of its new asp...
Tiny Lasers Plug ‘Green Gap’
TAMPERE, Finland, May 5, 2009 – Compact lasers can work in the 'green gap' -- formerly inaccessible parts of the spectrum -- and are suitable for mass production, thanks to pioneering work by a European consortium.
How to Get Grant and Venture Funding
Jan 12, 2009 — Your Research Needs the Right Acronym When I went to grad school, I assumed that I needed to do good research, but no one told me about the importance that acronyms have in the scientific community. Acronyms are absolutely necessary to call...
Ice’s Secrets Hold Promise for Green Projects
Oct 1, 2008 — LIVERMORE, Calif. – In a development that could have an impact on two vital areas – water purification and fuel cell design – researchers at Sandia National Laboratories have imaged ice a few nanometers thick as it forms bulk ice, a task heretofore...
Tight Squeeze on Light
BERKELEY, Calif., July 31, 2008 – Researchers at the University of California, Berkeley, have found a way to squeeze light through an opening that is only five times the width of a single piece of DNA. According to lead researcher, Xiang Zhang, mechanical engineering professor at UC...
Building Quantum Dots Slowly
Jul 1, 2008 — Quantum dots are small, with sizes measured in nanometers. And the size is important because it determines optical properties such as the emission peak of the particle. Bigger quantum dots have redder emission peaks. The problem with engineering the...
CNPs Inject Fluid into Cells
PHILADELPHIA, Jan. 18, 2008 -- Carbon nanopipettes (CNPs) thousands of times thinner than a human hair can measure electric current and probe cells without damaging them. The tiny carbon-based tools were created by University of Pennsylvania (Penn) engineers and physicians to...
Rapidly Counting Graphene Layers, One by One
Nov 1, 2007 — Carbon someday could rival silicon in forming the basis for miniature electronics. Two-dimensional sheets of carbon called graphene are promising candidates because they are stable and they move electrons rapidly. Furthermore, graphene-based devices...
A Single Dot Marks the Spot for Nanowire LEDs
Apr 1, 2007 — From wires nanometers in size, an industry hopes that mighty lights will grow. That goal — as well as the ability to perform quantum optics experiments — has gotten a boost, thanks to researchers from the Kavli Institute of Nanoscience at Delft...
Seeing More with Less
Oct 1, 2006 — When it comes to fluorescence microscopy, a team of investigators has shown that you can see more with less. Scientists at the Janelia Farm Research Campus of Howard Hughes Medical Institute (HHMI) in Ashburn, Va., at the National Institute of...
Dots Within Dots May Hit the Spot
Jun 1, 2006 — Like nested dolls, quantum dots can reside inside microspheres. Quantum dots are a few nanometers in diameter and have bright, size-dependent emission. A single wavelength can be used to excite dots of different sizes, making multiplexing possible....
'Road Map' for Nanoimprint Lithography Created
ATLANTA, April 26, 2006 -- Using a combination of experimental data and simulations, researchers have identified key parameters that predict the outcome of nanoimprint lithography, a fabrication technique that offers an alternative to traditional methods of patterning...
University of Rochester Receives Research Grant
Feb 1, 2006 — The University of Rochester’s Center for Electronic Imaging Systems in New York has received $1 million from the New York State Office of Technology and Academic Research to develop ways of shrinking computer circuits to the nanoelectronics scale....
Beyond 'Nano': A Scale That Weighs Viruses
Apr 7, 2004 — ITHACA, N.Y., April 7 -- Researchers have already been able to detect the mass of a single cell using submicroscopic devices. Now they're zeroing in on viruses. And the scale of their work is becoming so indescribably small, they have moved beyond...
Fibers Thinner Than Wavelengths of Light
Dec 23, 2003 — ARLINGTON, Va., Dec. 23 -- Researchers have developed a process to create wires only 50 nanometers (billionths of a meter) thick. Made from silica, the same mineral found in quartz, the wires carry light in an unusual way: Because the wires are...
