Researchers from North Carolina State University have developed a new technique for controlling the crystalline structure of titanium dioxide at room temperature.

Molecules and polymers have unique electronic and optical properties suitable for use in electronic devices. These properties, however, are complex and not well understood

(PhysOrg.com) -- Researchers from the NIST Center for Nanoscale Science and Technology have led the development of a new technique for efficiently out-coupling photons from epitaxially-grown quantum dots directly into a standard single-mode optical fiber.

It covers over two thirds of our planet, is essential for life on Earth and its chemical formula is one of the few most people can name, but we still have much to learn about the structure of H2O. Now, scientists working in Grenoble have developed a new technique using oxygen isotopes to study in detail the structure of disordered oxide materials such as water in biological processes or glasses in lasers and telecommunication devices

Light traveling in an optical fiber loses power over distance. A number of factors are responsible for this power loss, but one that is particularly important at high data rates is the loss that occurs due to changes in light polarization. Hui Dong at the A*STAR Institute for Infocomm Research and co-workers1 have developed and tested a method of determining this polarization-dependent loss (PDL) in an optical fiber cable by taking measurements from just one end of the fiber

Physicists from the University of California at San Diego (UCSD) have demonstrated a new technique to control the speed and direction of light using memory metamaterials whose properties can be repeatedly changed.

(PhysOrg.com) -- Stronger than steel or titanium -- and just as tough -- metallic glass is an ideal material for everything from cell-phone cases to aircraft parts. Now, researchers at the California Institute of Technology have developed a new technique that allows them to make metallic-glass parts utilizing the same inexpensive processes used to produce plastic parts. With this new method, they can heat a piece of metallic glass at a rate of a million degrees per second and then mold it into any shape in just a few milliseconds.
