Scientists at Argonne National Laboratory's CNM Nanophotonics Group have measured how light emission from individual colloidal semiconductor nanocrystals, or quantum dots, is modified when in proximity to smooth metal films.
The first artificial graphene has been created at the NEST laboratory of the Italian Institute for the Physics of Matter (INFM-CNR) in Pisa. It is sculpted on the surface of a gallium-arsenide semiconductor, to which it grants the extraordinary properties of the original graphene.
At a technical breakfast, Romain Quidant presented his research into the detection and treatment of cancer using gold nanoparticles illuminated with laser light.
Scientists at DuPont and Lehigh University have refined a technique, first published in 2003, to sort carbon nanotubes using specific sequences of DNA. This technique offers the first demonstration that nanotubes can be ...
It's commonly accepted that electrical resistance of a given material cannot be adjusted as is the case with, for example, density and color. However, Dr Meike Stöhr and her collaborators at the Paul Scherrer Institut (PSI) have now succeeded in developing a new method to selectively tune surface properties such as resistance.
A new microscope that views the subatomic universe -- the first of its kind in the world -- is being built for the University of Victoria, Canada, in collaboration with Hitachi High-Technologies.
The new microscope-c...
Air Products (NYSE:APD) has extended its XeCoverySM: xenon recovery service to recover xenon from XeF2-based etching processes, which will help stabilize and even lower the price of XeF2, noted Gene Karwacki, commercial development manager for XeCovery at Air Products, who was speaking at the SEMICON West 2009 Extreme Electronics TechXPOT.
Dr. Chunlei Guo and his team of researchers for the project discovered a way to transform a shiny piece of metal into one that is pitch black, not by paint, but by using incredibly intense bursts of laser light.
Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised* a viable way to manipulate a single “bit” in a quantum processor without disturbing the information stored in its neighbors. The approach, which makes novel use of polarized light to create “effective” magnetic fields, could bring the long-sought computers a step closer to reality.
Strem Chemicals, Inc, a manufacturer of specialty chemicals for research and development, announced that it has signed an exclusive agreement with Catalyx Nanotech to make Stacked Graphene NanoFibers (SGNF) available for...
