A million times better
Nonlinear optical materials are widely used in laser systems. However, high light intensity and long propagation are required to produce strong nonlinear optical effects. Researchers at the University of Texas at Austin and the Technische Universitaet Muenchen created metamaterials with a million times stronger nonlinear optical response, compared to the traditional nonlinear materials, and demonstrated frequency conversion in films 100 times thinner than human hair using light intensity comparable to that of a laser pointer.

New NIST metamaterial gives light a one-way ticket
NIST researchers have built a silver, glass and chromium nanostructure that can all but stop visible light cold in one direction while giving it a pass in the other. The device could someday play a role in optical information processing and in novel biosensing schemes.

NREL bolsters batteries with nanotubes
Researchers at the Energy Department's National Renewable Energy Laboratory are turning to extremely tiny tubes and rods to boost power and durability in lithium-ion batteries, the energy sources for cell phones, laptops, and electric vehicles. If successful, the batteries will last longer and perform better, leading to a cost advantage for electric vehicles.

How do ants get around? Ultra-sensitive machines measure their every step...
How do ants manage to move so nimbly whilst coordinating three pairs of legs and a behind that weighs up to 60 percent of their body mass? German scientists have recently developed a device that may reveal the answer and could even help design micro-robots in the future.

Study helps unlock mystery of high-temp superconductors
A Binghamton University physicist and his colleagues say they have unlocked one key mystery surrounding high-temperature superconductivity. Their research, published this week in the Proceedings of the National Academy of Sciences, found a remarkable phenomenon in copper-oxide (cuprate) high-temperature superconductors. Michael Lawler, assistant professor of physics at Binghamton, is part of an international team of physicists with an ongoing interest in the mysterious pseudogap phase, the phase situated between insulating and superconducting phases in the cuprate phase diagram.

Interlayer distance in graphite oxide gradually changes when water is added
Physicists from Umeå University and Humboldt University in Berlin have solved a mystery that has puzzled scientists for half a century. They show with the help of powerful microscopes that the distance between graphite oxide layers gradually increases when water molecules are added. That is because the surface of graphite oxide is not flat, but varies in thickness with 'hills' and 'valleys' of nanosize. The new findings are published in the scientific journal Nano Letters.

Silver in the washing machine
The antibacterial properties of silver-coated textiles are popular in the fields of sport and medicine. A team at Empa has now investigated how different silver coatings behave in the washing machine, and they have discovered something important: textiles with nano-coatings release fewer nano-particles into the washing water than those with normal coatings.

Bending the rules
For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate superconducting nanocircuitry. However, the extremely small zinc nanowires he designed did some unexpected -- and sort of funky -- things.

Let there be light: Chemists develop magnetically responsive liquid crystals
University of California, Riverside chemists have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research opens the door to display applications relying on the instantaneous and contactless nature of magnetic manipulation -- such as signage, posters, writing tablets, and billboards. Requiring no electrodes, the liquid crystals have applications in anti-counterfeit technology and optical communication devices for controlling the amplitude, phase, polarization, propagation direction of light.
