Litho Process Awarded $900K
Oct 26, 2009 — Cornell scientists who have invented a way of processing organic devices with a patent-pending process called orthogonal lithography have received a $900,000 grant from the National Science Foundation’s Materials World Network program. The funds, part of the American Recovery and Reinvestment Act, will last through 2013. The technique patterns materials using a photoresist that is soluble in environmentally safe fluorinated solvents for use in organic electronics. This protects the organic...
Shrimp Eyes That Polarize
BRISTOL, UK, Oct. 26, 2009 – Mantis shrimp, found on the Great Barrier Reef in Australia, have the most remarkable and complex vision systems known to science. They can see in 12 colors – humans see in only three – and can distinguish between different forms of polarized light....
Irish Fund Young Researchers
DUBLIN, Ireland, Oct. 23, 2009 – The Irish government awarded €7.9 million (about $11.8 million) to 15 young researchers at seven colleges and institutes in Cork, Dublin and Galway to support their ongoing work in semiconductor optoelectronics, next-generation computer chips and...
Linear Nanowires Kinked
CAMBRIDGE, Mass., Oct. 22, 2009 – Taking nanomaterials to a new level of structural complexity, Harvard University scientists determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging 2- and 3-D structures with correspondingly advanced...
Optical Trap Holds Viruses
BARCELONA, Spain, Oct. 22, 2009 – A Spain-Canada research collaboration developed a new method to gently trap, manipulate and study tiny, active objects as minuscule as viruses without inflicting any damage. The team demonstrated that it is possible to use the force of light to hold...
Electrons Lured From Graphene
NEW BRUNSWICK, N.J., Oct. 21, 2009 – Rutgers researchers discovered novel electronic properties in 2-D sheets graphene that could one day be the heart of speedy and powerful electronic devices. The new findings, previously considered possible by physicists but only now being seen in...
Molecules Made Mini Lasers
CAMBRIDGE, Mass., Oct. 21, 2009 -- A new optical microscopy technique squeezes photons out of nonfluorescent molecules to provide 3-D images of living cells and tissues for applications in medical imaging and biological research.
PV Energy Paths Controlled
GAINESVILLE, Fla., Oct. 21, 2009 – University of Florida chemists have pioneered a method to tease out promising molecular structures for capturing energy, a step that could speed the development of more efficient, cheaper solar cells. Kleiman’s work focuses on molecules known as...
Raydiance Sets Milestone
Oct 21, 2009 — Petaluma, Calif.-based laser company Raydiance Corp. announced it has made a major breakthrough in manufacturing a wide variety of bioabsorbable materials with precise, micron-resolution feature sizes and with no heat-affected zones. Raydiance has...
Neuroscience Show a Big Draw
CHICAGO, Oct. 20, 2009 -- Neuroscience 2009, the Society for Neuroscience's 39th annual meeting, provides the world's largest forum for neuroscientists to debut research and network with colleagues from around the world. The meeting provides emerging research news about...
Yale Engineer Wins Fellowship
Oct 20, 2009 — Yale University in New Haven, Conn., announced that Hong Tang, an assistant professor of engineering at its School of Engineering & Applied Science (SEAS), is one of 16 US scientists selected as a 2009 Packard Fellow. Tang’s research in...
Lasers Twist Fly Memories
OXFORD, England, Oct. 19, 2009 -- Light has been used to manipulate the memories of fruit flies, allowing them to learn from mistakes they never made and scientists to pinpoint the nerve cells that regulate such actions. The work could provide valuable information about how memories...
Silicon Chips May Go 'Green'
SAN JOSE, Calif., Oct. 16, 2009 -- Harvesting optical energy currently lost through heat dissipation in optoelectronic devices could allow them to actually generate more power than they use and help make silicon chips and compound semiconductors more "green," said Sasan Fathpour,...
A Closer Look at Betelgeuse
CERRO PARANAL, Chile, Oct. 15, 2009 – Two independent teams of astronomers have obtained the sharpest-ever views of one of the biggest stars in the sky – a red supergiant called Betelgeuse. One of the most luminous stars known, Betelgeuse emits more light than 100,000 suns. But it is...
FiO: Notes from the Crucible
SAN JOSE, Calif., Oct. 15, 2009 – “Whoa, whoa, whoa,” I thought. “Whoa.” I had just stumbled across a page on the Frontiers in Optics Web site collecting blog postings about the (then) upcoming meeting. “We can’t have people just running around writing stuff for the Internet. About...

Nanostrings Serve as Probes
GARCHING, Germany, Oct. 14, 2009 – New fabrication techniques have enabled the development of on-chip mechanical elements with dimensions on the nanometer scale. Their application, however, has been limited by the lack of sufficiently sensitive techniques for measuring the motion of...
Quantum Signatures of Chaos
TUCSON, Ariz., Oct. 9, 2009 – No one has produced experimental evidence that chaos occurs in the quantum world – the world of photons, atoms, molecules and their building blocks – until now. In a series of experiments, professor Poul Jessen and a group at the University of...
UV Curing Makes Inroads into PV Materials
Oct 9, 2009 — UV curing of polymers is well-known for many applications, including wood coatings, graphic arts, electronics and optics. In the photovoltaics (PV) industry, however, with some notable exceptions, UV curing has not been accepted commercially because...
360º IR Sensor Flown on UAS
Oct 8, 2009 — Lockheed Martin of Bethesda, Md., has announced that it has successfully tested a new infrared sensor turret aboard its Desert Hawk III unmanned aircraft system (UAS), marking the first time a small UAS has flown with a 360° IR sensor. According to...
Machine Mimics Human Vision
CHESTNUT HILL, Mass. Oct. 8, 2009 – Human vision is designed to look at the rough outlines of the various objects before examining the details. This improves the speed and accuracy of our image recognition, while machine vision typically performs the task in the opposite manner.
Seeing Inside a Living Cell
CAMBRIDGE, Mass., Oct. 8, 2009 – Electron microscopes are the most powerful type of microscope, capable of distinguishing even individual atoms. However, these microscopes cannot be used to image living cells because the electrons destroy the samples. Now, MIT assistant...
Light Travels a One-Way Road
CAMBRIDGE, Mass., Oct. 7, 2009 -- A new magnetic class of photonic crystals developed by physicists at MIT allows electromagnetic waves to flow freely in one direction only, a phenomenon that could lead to photonic devices, such as optical waveguides, with zero scattering loss.
