Latest Exciton Stories
Kiel researchers discover novel state of crystal matterNature knows two opposite types of solids: one that emerges upon compression from a liquid and a second that appears if the pressure on a liquid is reduced. While the former is typical for substances in our everyday life the latter occurs for example in a dense quantum liquid of electrons (such as in metals) or ions (in exotic white dwarf or neutron stars). Now it has been shown that there exists yet a third form of matter that inherits...
Researchers study quantum dots to increase the amount of electricity solar panels produceStudies done by Mark Lusk and colleagues at the Colorado School of Mines could significantly improve the efficiency of solar cells. Their latest work describes how the size of light-absorbing particles--quantum dots--affects the particles' ability to transfer energy to electrons to generate electricity.The results are published in the April issue of the journal ACS Nano.The advance provides evidence to...
ADDISON, Texas, Jan. 19, 2011 /PRNewswire/ -- ULURU Inc. (NYSE Alternext: ULU) announced today that it has signed a Binding Letter of Intent ("Agreement") with Exciton Technologies Inc. ("Exciton") to develop and market a product that will combine Altrazeal® with Exciton's proprietary exSALT(TM) Antimicrobial Technology. Under the terms of the agreement ULURU will be granted a worldwide license, excluding China, to market the Altrazeal® exSALT(TM) product. Exciton will be responsible...
A team of researchers from North Carolina State University and the U.K. has found that the low rate of energy conversion in all-polymer solar-cell technology is caused by the structure of the solar cells themselves. They hope that their findings will lead to the creation of more efficient solar cells.Polymeric solar cells are made of thin layers of interpenetrating structures from two different conducting plastics and are increasingly popular because they are both potentially cheaper...
To exploit the quantum world to the fullest, a key commodity is entanglement"”the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another. Now, physicists at the Joint Quantum Institute (JQI), a collaborative organization of the National Institute of Standards and Technology (NIST) and the University of Maryland, have developed a promising new source of entangled photons using quantum dots tweaked with a laser. The...
Physicists at the University of California-San Diego say they've created speedy integrated computer circuits capable of working in very cold environments. The circuits, built with particles called excitons, can operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality, researchers said. The accomplishment follows the team's demonstration last summer of an integrated circuit capable of working at 1.5...
Physicists at UC San Diego have successfully created speedy integrated circuits with particles called "excitons" that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality.Their discovery, detailed this week in the advance online issue of the journal Nature Photonics, follows the team's demonstration last summer of an integrated circuit"”an assembly of transistors that is the building block for all...
EDMONTON, Aug. 5 /PRNewswire/ - Exciton Technologies Inc. today announced that the Company has received approval from the United States Food and Drug Administration (FDA) to market exSALT(TM) SD7 Wound Dressing, a product incorporating Exciton's patented platform coating technology utilizing silver oxysalts as the active ingredient. "This achievement represents a significant team effort and a strong belief in our product," stated Rod Precht, Exciton's President and Chief Executive Officer....
New research by a team of University of Toronto scientists could lead to substantial advancements in the performance of a variety of electronic devices including digital cameras.Researchers created a light sensor "“ like a pixel in a digital camera "“ that benefits from a phenomenon known as multi-exciton generation (MEG). Until now, no group had collected an electrical current from a device that takes advantage of MEG."Digital cameras are now universal, but they suffer from a major...
 Researchers at the Harvard School of Engineering and Applied Sciences (SEAS), in collaboration with researchers from Worcester Polytechnic Institute (WPI), have demonstrated, for the first time, that the activation energy of impurities in semiconductor nanowires is affected by the surrounding dielectric and can be modified by the choice of the nanowire embedding medium.The finding, published in the April 6 issue of Applied Physics Letters, helps to confirm the "dielectric confinement...
