The first published scientific results from the world's most powerful hard X-ray laser, located at the Department of Energy's SLAC National Accelerator Laboratory, show its unique ability to control the behaviors of individual electrons within simple atoms and molecules by stripping them away, one by one - in some cases creating hollow atoms.
The bottled water, soda pop, or micro brew-beer that you drank in Pittsburgh, Dallas, Denver or 30 other American cities contains a natural chemical imprint related to geographic location. When you consume these beverage you may leave a chemical imprint in your hair that could be used to track your travels over time, a new study suggests.
The 2010 Millennium Technology Prize was awarded in June 2010 in Helsinki to Professor Michael Graetzel, who discovered dye-sensitized solar cells (DSC), also known as 'Graetzel cells'. In the New Energy Technologies Group, led by Professor Peter Lund from the Department of Applied Physics at Aalto University, research in DSCs has been carried out since 2001.
The American National Standards Institute (ANSI) and the ANSI-accredited US Technical Advisory Group (TAG) to ISO/TC 229, Nanotechnologies invites all U.S. interested stakeholders to provide input on a proposed draft Technical Specification (TS) that addresses the labeling of manufactured nano-objects and products containing manufactured nano-objects at an upcoming webinar, scheduled for Friday, July 9, 2010.
Researchers are exploring the capabilities of diamond nitrogen vacancy materials. In this material, a molecule at the heart of an artificially created diamond film consists of a nitrogen atom (present as in impurity amid all those carbon atoms) and a nearby vacancy, a place in the crystal containing no atom at all. These diamond structures offer the possibility of carrying out data storage and quantum computing at room temperature.
New research details the production of highly stable glass films of indomethacin by physical vapor deposition. Researchers used alternating current nanocalorimetry to evaluate the heat capacity of the thin glass films.
According to Maxime Darnon, a researcher at the French National Center for Scientific Research, in order to continue increasing the speed of integrated circuits, interconnect insulators will require an upgrade to porous, low-dielectric constant materials.
Inspired by the ease with which gecko lizards can move on almost any surface, researchers at Northeastern University, the Korea Institute of Science and Technology and Seoul National University hope to reproduce properties found in the gecko's footpad for applications ranging from adhesives to robotic movement and navigation.
Making better solar cells: Cornell University researchers have discovered a simple process - employing molecules typically used in blue jean and ink dyes - for building an organic framework that could lead to economical, flexible and versatile solar cells.
Photoemission has been explained as a process in which an electron is instantly ejected from an atom after the atom absorbs energy from a photon. Now, EU-funded physicists have shown that this does not happen immediately. In proving that there is a delay after the photon impacts the electron, the team has succeeded in measuring the shortest time ever to be recorded in nature.
