Researchers report an advance toward the goal of cars that run on hydrogen rather than gasoline. While the U.S. Department of Energy estimates that practical hydrogen fuel will require concentrations of at least 6.5 percent, the chemists have achieved concentrations of 7.5 percent ? nearly three times as much as has been reported previously ? but at a very low temperature (77 degrees Kelvin).
Liquid crystals, the same phase-shifting materials used to display information on cell phones, monitors and other electronic equipment, can also be used to report in real time on the differentiation of embryonic stem cells.
The National Institute of Advanced Industrial Science and Technology (AIST) in Japan has successfully developed the first basic device structure extendable to multi-quantum-bits for an optically controlled quantum logic gate.
The centre's main areas of research include nano research, developing new products, producing medical protheses, multi-component fluids with nano-dispersal technology and applying nanotechnology in meteorology.
The French National Institute for Health and Medical Research (Inserm), the engineering university INSA Lyon, and Riken, a Japanese research centre for biomedicine, signed an agreement to establish a joint laboratory studying lipids nanostructures.
A team of researchers has developed a new process to make flexible, conducting "nano skins" for a variety of applications, from electronic paper to sensors for detecting chemical and biological agents.
A review of published toxicology studies argues that there are as yet no ways to predict which quantum dots will be toxic and which will be safe, making it necessary to test each type of quantum dot for toxicity before reaching any conclusions about their clinical utility.
Two groups of investigators in Europe have developed engineered nanoscale materials that enhance images obtained using magnetic resonance (MR) imaging. With further development, these nanomaterials have the potential to improve the detection of early stage cancer.
