A recently released OECD document, Important Issues on Risk Assessment of Manufactured Nanomaterials, provides the current practices, challenges and strategies for assessing risk in circumstances where data are limited, and there is a necessity for more research on specific risk assessment issues.
A sponge made of pure carbon nanotubes with a dash of boron shows remarkable ability to absorb oil spills from the surface of water, according to researchers at Rice University and Penn State University. The oil can be stored in the sponge for later retrieval or burned off so the sponge can be reused.
Like special-forces troops laser-tagging targets for a bomber pilot, tiny particles that can be imaged three different ways at once have enabled Stanford University School of Medicine scientists to remove brain tumors from mice with unprecedented accuracy.
A team from the University of North Carolina at Chapel Hill demonstrates a simple, cost-effective technique for three-dimensional RNA structure prediction that will help scientists understand the structures, and ultimately the functions, of the RNA molecules that dictate almost every aspect of human cell behavior.
An innovative X-ray technique has given North Carolina State University researchers and their collaborators new insight into how organic polymers can be used in printable electronics such as transistors and solar cells. Their discoveries may lead to cheaper, more efficient printable electronic devices.
The ability to control the flow of electrons using engineered materials is fundamental to the information technology revolution, yet many properties of matter are still unclear. Now a University of Alberta researcher is closer to understanding some of the exotic electronic properties in matter using optical analogues.
The IEEE Photonics Society's 2012 International Group IV Photonics Conference announces a Call for Papers seeking new research in silicon photonics as well as photonics materials and devices based on Group IV elements.
Electron microscopy, conducted as part of the Shared Research Equipment (ShaRE) User Program at the Department of Energy's Oak Ridge National Laboratory, has led to a new theory to explain intriguing properties in a material with potential applications in capacitors and actuators.
The fixtureless and noncontact technique, known as the magnetically actuated peel test (MAPT), could help ensure the long-term reliability of electronic devices, and assist designers in improving resistance to thermal and mechanical stresses.
Scientists in Sweden have developed a molecular catalyser with the ability to quickly oxidise water to oxygen. The results are a significant contribution to the future use of solar energy and other renewable energy sources, especially since gasoline prices continue to soar.
As part of a larger consortium involving partners from several energy companies, universities, and government agencies, researchers at the U.S. Department of Energy's Argonne National Laboratory are developing a special class of nanoparticles that partially melt as steam evaporates from a plant's cooling towers, absorbing a significant percentage of the diffused heat in the system.
Realizing the crucial role of utilizing nanotechnology in everyday life, Thailand is taking necessary steps to building public awareness to direct and indirect effects of nanomaterials and naaoproducts to health and environment.
The computer industry is nearing a crisis: microchips get smaller and faster but they struggle to transfer data at sufficient speeds. Electrons flowing through standard chip connections are just too slow. Now EU-funded researchers have shown how chips with built-in lasers which use multiple wavelengths of light could in the future transmit data at terabit speeds.
