Optical Nanocircuits Could Replace Conventional Electronics

US researchers believe that tiny optical versions of capacitors, resistors and inductors can be made by adjusting the size, shape and composition of sub-wavelength nanoparticles.

Light Pulses Caught using Photonic Crystal Resonator

A team from Kyoto University has demonstrated a method for dynamically changing the lifetime of a photonic crystal resonator, which in effect can trap a pulse of light inside the system. Susumu Noda and his colleagues showed that the Q factor of their system, a measure of the number of time periods of light after which most of the light has left the system, could be increased by a factor of four from 3,000 to 12,000 within just a few picoseconds.

TR-LIFS Combined with Other Diagnostic Technologies to Help Prevent Deaths Related to Heart Attacks

Prescient Medical, Inc., a privately held medical device company dedicated to reducing deaths from heart attacks, announces the acquisition of a new technology that identifies and quantifies metabolic activity and inflammation in human artery tissue by measuring the time it takes for light to dissipate after the tissue has been excited with ultra-short light pulses.

Researchers Demonstrated World's Smallest Microwave Oven

Researchers at the National Institute of Standards and Technology (NIST) and George Mason University have demonstrated what is probably the world's smallest microwave oven, a tiny mechanism that can heat a pinhead-sized drop of liquid inside a container slightly shorter than an ant and half as wide as a single hair.

New Technique Makes Imaging Individual Atoms 100 Times Faster

Using an existing technique in a novel way, Cornell physicist Keith Schwab and colleagues at Cornell and Boston University have made the scanning tunneling microscope (STM) -- which can image individual atoms on a surface -- at least 100 times faster.

Road Signs with Variable Reflectivity Based on Weather Conditions

Imagine paint that adheres to a surface, but releases on command or road signs that change their reflectivity with changing weather conditions. These are two potential uses of a novel, responsive material designed by researchers in the University of Massachusetts Amherst polymer science and engineering department. The research was published online this week in the journal Advanced Materials.
