Crystals and ceramics pale when compared to a material researchers at Oak Ridge National Laboratory discovered that has 10 times their piezoelectric effect, making it suitable for perhaps hundreds of everyday uses. ORNL's Volker Urban and colleagues at Technical University Aachen in Germany noticed the reverse piezoelectric effect - defined as creating a mechanical strain by applying an electrical voltage -- while conducting fundamental research on polymers. At first they didn't think...

A blast of gamma radiation could toughen up plastic prosthetic joints to make them strong enough to last for years, according to researchers in China writing in the current issue of the International Journal of Biomedical Engineering and Technology. Whole joint replacement, such as hip and knee replacement, commonly use stainless steel, titanium alloys or ceramics to replace the damaged or diseased bone of the joint. Non-stick polymer or nylon is usually used to coat the artificial joint...

A new physics-based theory could give researchers a deeper understanding of the unusual, slow dynamics of liquids composed of large polymers. This advance provides a better picture of how polymer molecules respond under fast-flow, high-stress processing conditions for plastics and other polymeric materials. Kenneth S. Schweizer, the G. Ronald and Margaret H. Professor of materials science and engineering at the University of Illinois, and graduate student Daniel Sussman published their...

"The strength of spider dragline silk exceeds that of any material produced in laboratories, by far. All attempts to manufacture threads of similar strength have failed thus far," explains Professor Horst Kessler, Carl von Linde Professor at the Institute for Advanced Study at the TU Muenchen (TUM-IAS). In collaboration with the workgroup of Prof. Thomas Scheibel, who was a researcher at the TU Muenchen until 2007 and who now holds a chair of the Institute of Biomaterials at the Universitaet...

Researchers from North Carolina State University have developed a simple, scalable way to align gold nanorods, particles with optical properties that could be used for emerging biomedical imaging technologies. Aligning gold nanorods is important because they respond to light differently, depending on the direction in which the nanorods are pointed. To control the optical response of the nanorods, researchers want to ensure that all of the nanorods are aligned. The NC State researchers...

Decades after the bullets have stopped flying, wars can leave behind a lingering danger: landmines that maim civilians and render land unusable for agriculture. Minefields are a humanitarian disaster throughout the world, and now researchers in Scotland have designed a new device that could more reliably sense explosives, helping workers to identify and deactivate unexploded mines. The prototype sensor features a thin film of polymer whose many electrons jump into higher energy levels when...

Newly synthesized polymer, fitted with molecular pincers of carefully tailored structure, effectively captures nicotine molecules and its analogues. The polymer can be used for fabrication of sensitive and selective chemical sensors to determine nicotine in solutions, and in the near future also in gases. Moreover, the polymer is suitable for slow, controlled release of nicotine, e.g., for therapeutic purposes. The collaboration of researchers of the Institute of Physical Chemistry of the...
