CNProbes Partners with MEMS Foundry
Jul 24, 2008 — CNProbes, an emerging nanotech solutions provider, has executed an agreement with MEMS Foundry, a contract manufacturer. This agreement puts CNProbes closer to ramping up full-scale production and launch of CNProbes’ flagship product, a carbon nanotube probe tip for use in the atomic force microscope (AFM). The key business challenge to the commercialization of carbon nanotube probe tips has been scalable production. CNProbes is the first manufacturer in the world to be able to scalably...
Subsurfaces Seen Sharply
LAUSANNE, Switzerland, July 21, 2008 -- The high penetration power of x-rays has been combined with diffraction imaging to create a novel x-ray microscope that makes it possible, for the first time, to view the detailed interiors of semiconductor devices and cellular structures. The...
An LCD Built with Graphene
Jul 1, 2008 — According to a team of researchers from the UK and Russia, thin sheets of carbon could improve LCDs. The group recently demonstrated that graphene — a two-dimensional layer of carbon — can be used to make the conducting transparent thin films...
An Open Letter to Google
Jul 1, 2008 — Google.com frequently celebrates historic people and events on its home page, showcasing art by the company’s international Webmaster, Dennis Hwang. For example, the company annually observes major holidays and has commemorated the birthdays of such...
Building a Pocket-Size Electron Accelerator
Jul 1, 2008 — Might it be possible to combine today’s commercial laser technology with micro- and nanoscale manufacturing techniques to produce tabletop or even pocket-size particle accelerators? This has been the dream of many research groups around the world,...
Confocal Microscopy Enables Direct Observation of Photonic Nanojets
Jul 1, 2008 — If you shine a beam of light onto a sphere just a few microns in diameter, an unusual effect takes place: On the side opposite where the beam strikes, a local field enhancement shaped like a tiny jet tail appears. Called photonic nanojets, these...
Defect-Free Structures May Pave the Way to GaAs Lasers
Jul 1, 2008 — If you are an optoelectrical engineer trying to create semiconductor devices that emit light, here is some advice: Don’t let zinc blende get into your wurtzite. In recent years, gallium arsenide has gained traction as the basis for optoelectronic...
Determining the Composition of Quantum Dots from Top to Bottom
Jul 1, 2008 — Quantum dots may shine, but shedding light on their make-up has proved to be difficult because they are small, with sizes in the tens of nanometers. Several analysis techniques average over many quantum dots, smoothing out possible variations....
Fluorescence Tracks Down Hidden Bacteria
Jul 1, 2008 — Bacteria are everywhere. They are in the water, they are in the ground and they are all over you. The vast majority of them are harmless, but certain bacteria produce polysaccharides — complex carbohydrates that tend to aggregate, enabling the...
Parabolic Reflector Couples Between Fiber and Silicon-on-Insulator Waveguide
Jul 1, 2008 — Optical fibers and silicon-on-insulator waveguides both are crucial to today’s photonic systems, but coupling between the two is problematic. The small, tightly confined modal area in a silicon-on-insulator waveguide with high-index contrast...
Raman Spectroscopy Detects First Signs of Tooth Decay
Jul 1, 2008 — Dentists commonly use x-rays and metal picks to detect cavities, but Raman spectroscopy could detect tooth decay earlier. With low power and near-IR excitation, it could do so more safely than x-rays and without pain. Recently, researchers...
Supercomputing May Require Bugs
Jul 1, 2008 — If you were looking for a diamond in the rough, would you think to look on the backs of beetles? One group of researchers did, and found a photonic gem worth taking to the bank. The ultimate photonic crystal would manipulate light so efficiently...
Agilent Buys Nano Instruments
SANTA CLARA, Calif., June 30, 2008 -- Measurement company Agilent Technologies Inc. announced today it has acquired the Nano Instruments business unit of MTS Systems Corp for an undisclosed amount to strengthen its nanomeasurement product portfolio. Founded in 1983 and based in Oak...
Laser Microscalpel Created
AUSTIN, Texas, June 25, 2008 – Femtosecond lasers have just become more accurate and versatile, thanks to Adela Ben-Yakar, mechanical engineering assistant professor at The University of Texas at Austin. By nature, Femtosecond lasers produce extremely brief, high-energy light...
Solar Research Tops Agenda
SAN DIEGO, June 24, 2008 -- The latest research, technologies and applications in solar and alternative energies, nanotechnology, organic LEDs, optical design and remote sensing will be discussed at SPIE Optics+Photonics 2008, the largest optical sciences and technology...

A Worm of a Different Color
BUFFALO, N.Y. , June 17, 2008 -- A mutant worm changes color when it moves as the result of an optical sensor called stFRET. The sensor is composed of a pair of fluorescent molecules connected by a molecular spring that is inserted into structural proteins in the worm's cells....
Conjuring Robert Koch
THORNWOOD, NY, June 10, 2008 – Today, one in three persons is infected with the tuberculosis pathogen, and the World Heath Organization (WHO) estimates that there will be 30 million deaths caused by tuberculosis in the next year, due to the development of multi-resistant strains...
Sizing Up Graphene
BERKELEY, Calif., June 9, 2008 -- The extraordinary properties of graphene have reportedly been measured with an accuracy never before achieved, confirming many of its strangest features but revealing significant departures from theoretical predictions. Results of research at the...
Partnership for Live-cell Research
MELVILLE, NY, June 4, 2008 – Nikon Instruments and Northwestern University are opening a collaborative core microscopy imaging center that will improve research capabilities at the University while providing Nikon with critical product development feedback. One of only three...
Cell Invasion on Agenda
Jun 3, 2008 — The cellular aspects of infection, including cell invasion and host-pathogen interactions, will be the topic of a one-day meeting to be co-sponsored by the Royal Microscopical Society (RMS) and the Society for General Microbiology (SGM) during...
