LOS ANGELES, Aug. 31, 2011 — A compact, lightweight, dual-mode microscope that uses holograms instead of lenses could prove to be a boon for global health initiatives. The palm-size device, developed at UCLA, costs only $50 to $100 to make. It features a transmission mode...
New Nanomaterials Control, Direct Light Energy
TORONTO, Canada, July 18, 2011 — Inspired by photosynthesis, researchers have engineered a new generation of nanomaterials that control and direct the energy absorbed from light. "Nanotechnologists have for many years been captivated by quantum dots — particles of...
Lens-free chip enables microfluidic integration
LOS ANGELES – A new lens-free chip and image processing algorithm combines optical sensors, holography and digital tomography to render high-resolution, high-contrast images while avoiding the limitations of lens-based optical microscopy. Developed by scientists...
Microfluidic HIV Test: Quick and Cheap
DAVIS, Calif., July 20, 2010 — A new lab-on-a-chip HIV testing device could make testing in developing nations easier and more affordable. UC Davis biomedical engineer Alexander Revzin developed the microfluidic device, which uses antibodies to “capture” white blood...
Revealing Cell Membrane Mechanics
CHAMPAIGN, Ill., April 29, 2010 — Thanks to an interdisciplinary team of researchers, scientists now have a more complete understanding of one of the human body’s most vital structures, the red blood cell. Led by University of Illinois electrical and computer engineering...
Lensless Microscope Made for Telemedicine
LOS ANGELES, April 27, 2010 — Aydogan Ozcan, whose invention of a novel lensless imaging technology for telemedicine could radically transform global health care, has now taken his work a step further. The University of California, Los Angeles engineer has created a miniature...
New Spintronics Material for Next-Gen Chips
LOS ANGELES, April 8, 2010 — As the electronics industry works toward developing smaller and more compact devices, the need to create new types of scaled-down semiconductors that are more efficient and use less power has become essential. Researchers from UCLA's Henry...
Rayle to Lead Schott Advanced Materials Unit
DURYEA, Pa., March 18, 2010 – Schott has named Dr. Heather Rayle as vice president and general manager for its advanced materials business unit in North America. Rayle held various positions with Rohm and Haas...

Dimple lens goes beyond the diffraction limit
LOS ANGELES – University of California scientists have created a new type of lens that can focus light down to a sub-100-nm spot. This record-breaking focusing power could open up new areas of research in biological sciences, nonlinear optics and near-field...
Back to green school
Sep 1, 2009 — Renewable energy technologies are everywhere, but nowhere are they more prevalent than on college and university campuses around the globe. Sustainability is the name of the game when it comes to curriculum development, research funding, student...
Dissolving CIGS for flexible application
Sep 1, 2009 — Solar cell designs traditionally are based on crystalline silicon, but not only has that material been in short supply, the silicon-solar process is relatively expensive. And as the solar industry strives to decrease the cost to make it a viable...
It’s Two, Two, Two Tools in One
Sep 1, 2009 — If a surgeon is about to use a probe in the brain, the patient is sure to want that probe to be as small as possible. And three University of California, Los Angeles (UCLA), researchers have developed technology that could lead to tinier probes that...

LOS ANGELES, May 1, 2009 – Engineers at UCLA have developed a (video) camera that captures images in real time at 6 million fps, or 1000 times faster than its predecessors. It may be used for flow cytometry to diagnose cancer.
'Rogue' Light Waves Tamed
LOS ANGELES, March 6, 2009 – Rare and explosive flare-ups known as "rogue" light waves have been tamed to produce brighter, more stable white light sources.
'Rogue' Light Waves Tamed
LOS ANGELES, March 6, 2009 – A rogue wave at sea spontaneously emerges and because of its enormity, can be extremely destructive for all in its path. However, rogue waves of light, which are rare and explosive flare-ups that are mathematically similar to their oceanic...
Optical Fiber, Silicon Core
CLEMSON, SC, Oct. 28, 2008 – Scientists at Clemson University for the first time have been able to make a practical optical fiber with a silicon core, according to the Optical Society of America (OSA). The ability to produce silicon fibers commercially would create the...
The Dancing Aurora Borealis
LOS ANGELES, Calif., July 25, 2008 – Space scientists at the University of California, Los Angeles (UCLA) believe they have solved some of the mystery behind the northern lights phenomenon. For the past 30 years, there have been two competing theories to explain the onset of...
Lensless Camera Uses X-rays
ARGONNE, Ill., Feb. 21, 2008 -- A lensless camera uses x-rays to take high-resolution images of ultrasmall structures buried inside nanoparticles, nanomaterials, and biological specimens. Scientists at Argonne National Laboratory, in collaboration with those from the...
