Scientists from the UK's National Physical Laboratory have developed a nano-device which could change the way we define electrical current A team of scientists at the National Physical Laboratory (NPL) and University of Cambridge has made a significant advance in using nano-devices to create accurate electrical currents. Electrical current is composed of billions and billions of tiny particles called electrons. NPL scientists have developed an electron pump — a nano-device —...

[ Watch the Video ] John Neumann for redOrbit.com - Your Universe Online Researchers have succeeded in tracking a single protein that regulates the neurotransmitter serotonin, making it possible to study the dynamics of the protein which regulates mood, appetite and sleep, at an unprecedented level of detail, reports David Salisbury of Vanderbilt University. Attempts to understand how these transporters work have been limited by the difficulty of studying their dynamic behavior. The...

Researchers are edging toward the creation of new optical technologies using "nanostructured metamaterials" capable of ultra-efficient transmission of light, with potential applications including advanced solar cells and quantum computing. The metamaterial - layers of silver and titanium oxide and tiny components called quantum dots - dramatically changes the properties of light. The light becomes "hyperbolic," which increases the output of light from the quantum dots. Such materials...

Efficient, Tunable Interface For Quantum Networks
2012-05-23 12:59:16

Quantum technologies promise to redefine the landscape of information processing and communication. We already live in an information age, in which vast amounts of data are sent around the world over optical fibers, but future quantum networks may be many times more powerful. These networks will require interfaces that can transfer information from quantum processors onto light particles (photons). Such interfaces will allow optical fibers to transmit information-bearing photons between...

Medical uses for quantum dots -- tiny luminescent crystals -- could include image-guided surgery, light-activated therapies and sensitive diagnostic tests A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine. The research, which will appear on May 20 in Nature Nanotechnology online, is likely the...

Kansas State University researchers have come closer to solving an old challenge of producing graphene quantum dots of controlled shape and size at large densities, which could revolutionize electronics and optoelectronics. Vikas Berry, William H. Honstead professor of chemical engineering, has developed a novel process that uses a diamond knife to cleave graphite into graphite nanoblocks, which are precursors for graphene quantum dots. These nanoblocks are then exfoliated to produce...

New Research Could Peg Quantum Dots As Future Of Lighting

Researchers are looking to white-light quantum dots as the future of lighting. White-light quantum dots are ultra-small fluorescent beads of cadmium selenide that are able to convert blue light produced by an LED into a warm white light similar to an incandescent light. Vanderbilt University researchers are reporting that they have successfully boosted the fluorescent efficiency in nano crystals from an original level of three percent to as high as 45 percent.  This feat proves...

Switching light with light: only 140 photons are needed An optical switch developed at the Joint Quantum Institute (JQI) spurs the prospective integration of photonics and electronics. What, isn't electronics good enough? Well, nothing travels faster than light, and in the effort to speed up the processing and transmission of information, the combined use of light parcels (photons) along with electricity parcels (electrons) is desirable for developing a workable opto-electronic protocol....


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
