Standoff sensing enters new realm with dual-laser technique
(PhysOrg.com) -- Identifying chemicals from a distance could take a step forward with the introduction of a two-laser system being developed at the Department of Energy's Oak Ridge National Laboratory.
Metamaterials may advance with new femtosecond laser technique
Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways.
Two crystals linked by quantum physics
Physicists take a perverse pleasure in playing with the strangeness of the quantum world. That's how they have managed to entangle minuscule objects such as photons. After specific manipulations, they persuade two photons ...
All-carbon-nanotube transistor can be crumpled like a piece of paper
Virtual ghost imaging: New technique enables imaging even through highly adverse conditions
Ghost imaging (GI), and its even more oddly named cousin virtual ghost imaging (VGI), seem to contradict conventional wisdom by being able to image an object by simply counting photons in a "light bucket." This non-intuitive ...
New 'soft' motor made from artificial muscles
The electrostatic motor, used more than 200 years ago by Benjamin Franklin to rotisserie a turkey, is making a comeback in a promising new design for motors that is light, soft, and operates without external electronic controllers.
New nano-material combinations produce leap in infrared technology
Arizona State University researchers are finding ways to improve infrared photodetector technology that is critical to national defense and security systems, as well as used increasingly in commercial applications and consumer ...
'Flipped classroom' teaching model gains an online community
Researchers at Harvard University have launched the Peer Instruction (PI) Network, a new global social network for users of interactive teaching methods.
Innovation promises expanded roles for microsensors
Researchers have learned how to improve the performance of sensors that use tiny vibrating microcantilevers to detect chemical and biological agents for applications from national security to food processing.
Building a better light bulb
Scientists study the movement of charge carriers to design an organic LED that is energy efficient and still casts a warm, natural glow.
Wireless power could revolutionize highway transportation, researchers say
A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The ...
Flaky graphene makes reliable chemical sensors
Scientists from the University of Illinois at Urbana-Champaign and the company Dioxide Materials have demonstrated that randomly stacked graphene flakes can make an effective chemical sensor.
Light makes write for DNA information-storage device
Researchers have demonstrated a write-once-read-many-times information-storage device, made of DNA embedded with silver nanoparticles, that uses ultraviolet light to encode data.
Trapping butterfly wings' qualities
Butterflies have inspired humans since the time of ancient Egypt, but now they're also inspiring researchers to look toward nature to help create the next generation of waterproof materials for electronics ...
