Theoretical Advancement Could Enable High-Coherence Fano Lasers
KONGENS LYNGBY, Denmark, Sept. 2, 2021 — Researchers at the Technical University of Denmark (DTU) have shown that a Fano laser has fundamental advantages over other types of microscopic lasers. The researchers demonstrated that the coherence of a Fano laser can be significantly improved,...
Lasers Allow Mass-Producible Microscopic Robots to Walk
ITHACA, N.Y., Sept. 1, 2020 — A collaboration led by Cornell University has created microscopic robots with semiconductor components that allow them to be controlled and made to walk with laser light and standard electronic signals. The robots are roughly the size of a...
Adaptive Optics Detect Early Diabetes Eye Damage
BLOOMINGTON, Ind., April 21, 2014 — Vision loss is a threat for millions of those suffering from diabetes. The earlier it can be detected, the sooner and potentially more effectively it can be treated.
Atom Imaged in Ultracold Gas
CAMBRIDGE, Mass., Nov. 5, 2009 – A high-resolution microscope was developed to image individual atoms in an ultracold quantum gas, marking the first time scientists detected single atoms in a crystalline structure made solely of light called a Bose Hubbard optical lattice.
Sensor Peers into Electrons
CAMBRIDGE, Mass., Oct. 1, 2008 -- Physicists have exploited a special "flaw" in diamond crystals, manipulating them into monitoring magnetic signals from individual electrons and atomic nuclei and allowing scientists to spy on some of the universe's tiniest building blocks. The...
Light Pulse Speed Record Set
GARCHING, Germany, July 2, 2008 -- Researchers have set a new record in ultrafast metrology, producing the first light pulses lasting only 80 attoseconds (a billionth of a billionth of a second). Electrons move at awesome speeds, so any observation of that motion has to also be...
Light Creates Tiny Patterns
PRINCETON, N.J., June 20, 2008 -- The old trick, practiced by schoolboys everywhere, of concentrating a beam of sunlight through a magnifying lens to ignite paper -- or an unfortunate ant -- has been given a new twist. By using a microscopic plastic bead in place of the lens and...
Microscopic Flow of Non-Brownian Systems Probed
Apr 1, 2008 — Understanding the microscopic dynamics that occur between a flowing fluid and an elastic solid, such as those that happen in plastics manufacturing and in numerous other industrial applications, can be an important parameter in quality...
Nanomagnets May Replace ICs
HOUSTON, Sept. 3, 2007 -- Just as compact discs all but wiped out vinyl records, semiconductors could be on their way out, too. Using magnetic cellular networks, or nanomagnets, a University of Houston (UH) professor has developed a similar "disruptive technology" that...
Nanomedical Advances Sought
WEST LAFAYETTE, Ind., & SEOUL, South Korea, July 10, 2007 -- A new nine-year collaboration between scientists in the US and South Korea will combine new imaging, biosensing and nanomedical techniques in an effort to advance medical diagnosis and treatment to the molecular level. Research teams from Purdue...
Optical Techniques Reveal Clues about Ancient ‘Comb Jelly’ Embryos
Jun 1, 2007 — The Meishucun assemblage of fossils in southwestern Shaanxi, China, documents the beginnings of the Cambrian explosion of animals roughly 540 million years ago — a period in which the diversity of skeletonized metazoans (multicellular animals that...
Lab-Created Lithoparticles Could Have Many Uses
LOS ANGELES, March 21, 2007 -- Billions of fluorescent microscale particles in the shapes of all 26 letters of the alphabet have been designed and produced in the lab. The letters are made of solid polymeric materials dispersed in a liquid solution, and the scientists who created...
Zeiss MicroImaging Buys Instrument Biz for $12.5M
ALISO VIEJO, Calif., & JENA, Germany, March 9, 2007 -- In a move the company said will strengthen its commitment to the growing field of clinical cancer diagnostics and cancer research, microscopy solutions provider Carl Zeiss MicroImaging GmbH has acquired the equipment business of California-based...
Visible Light Transmitted Through Nanocable
CHESTNUT HILL, Mass., Jan 8, 2007 -- Physicists have beamed visible light through a cable hundreds of times smaller than a human hair, an achievement they said could lead to advances in solar power and optical computing. The discovery made at Boston College defies a key...
Plastic, Crystal-Based Solar Cells Being Developed
BRISBANE, Australia, Sept. 7, 2006 -- A University of Queensland researcher is developing ways to make the next generation of solar cells made out of plastics and microscopic crystals instead of silicon. UQ master of physics student Michael Deceglie is working on improving the...
First ‘Molecular Movie’ of Light Made
OXFORD, England, Aug. 14, 2006 -- What happens on a microscopic level when light travels through a medium has been captured in the first "molecular movie" of the elementary interaction between light and matter. The research was done as part of a collaborative project involving...
Sandia, Monsanto Sign Cooperative Research Agreement
Aug 10, 2006 — Sandia National Laboratories of Livermore, Calif., which provides research and development for the US Department of Energy's National Nuclear Security Administration, and St. Louis-based agricultural product developer Monsanto Co. announced a...
Optoelectronic Tweezers Manipulate Microparticles
Aug 1, 2005 — In the July 21 issue of Nature, researchers from the University of California, Berkeley, report the development of a novel technique for the manipulation of microscopic objects by electrokinetic forces using a photoconductive sample cell. The...
