SAN MARCOS, Texas, May 14, 2013 /PRNewswire/ -- Quantum Materials Corporation (OTCQB:QTMM) has chosen to relocate its tetrapod quantum dot laboratories to San Marcos, Texas to take advantage of facilities at STAR Park (Science, Technology and Academic Research Park). STAR Park is a non-profit incubator with roots from nearby Texas State University, the fifth largest university in Texas and one of eight Texas Emerging Research Universities. The City of San Marcos, considered within...

Quantum dots are tiny nanocrystals with extraordinary optical and electrical properties with possible uses in dye production, bioimaging, and solar energy production. Researchers at the University of Illinois at Chicago have developed a way to introduce precisely four copper ions into each and every quantum dot. The introduction of these "guest" ions, called doping, opens up possibilities for fine-tuning the optical properties of the quantum dots and producing spectacular colors. "When...

California Lithium Battery is proud to announce its selection as a 2013 TechConnect National Innovation Awardee for the development of its breakthrough very-high specific capacity Lithium-ion silicon-graphene (SiGr) composite anode material. The Innovation Showcase is the world’s largest showcase and accelerator for industry-vetted emerging-technologies that are ready for commercialization. LOS ANGELES, CA (PRWEB) May 10, 2013 California Lithium Battery is proud to announce its...

Tweaking graphene chemical sensors may open up many applications Researchers have discovered a technique for controlling the sensitivity of graphene chemical sensors. The sensors, made of an insulating base coated with a graphene sheet--a single-atom-thick layer of carbon--are already so sensitive that they can detect an individual molecule of gas. But manipulating the chemical properties of the insulating layer, without altering the graphene layer, may yet improve their ability to...

The latest research from a Kansas State University chemical engineer may help improve humidity and pressure sensors, particularly those used in outer space. Vikas Berry, William H. Honstead professor of chemical engineering, and his research team are using graphene quantum dots to improve sensing devices in a twofold project. The first part involves producing the graphene quantum dots, which are ultrasmall pieces of graphene. Graphene is a single-atom thick sheet of carbon atoms and has...

Karlsruhe Institute of Technology By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon conducts heat around a central area without the edge being affected. The results are presented in the Physical Review Letters journal. “For the thermal invisibility cloak, both materials have to...

Lee Rannals for redOrbit.com – Your Universe Online Duke University engineers are developing a way for you to create your own visibility cloak with a 3D printer. Three-dimensional printing is growing in popularity, and the cost for a MakerBot Replicator 2 is now just $2,199. Scientists are also working harder and harder to turn Harry Potter's invisibility cloak into a reality. A group wrote in the New Journal of Physics in March about how they developed a new cloak that is able to...

University of Illinois University of Illinois researchers have developed a new way to produce highly uniform nanocrystals used for both fundamental and applied nanotechnology projects. “We have developed a unique approach for the synthesis of highly uniform icosahedral nanoparticles made of platinum (Pt),” explained Hong Yang, a professor of chemical and biomolecular engineering and a faculty affiliate at the Center for Nanoscale Science and Technology at Illinois. “This is...

University of Utah Nanocrystal semiconductor for photovoltaics, medical sensors, heat reuse University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity. Using microwaves "is a fast way to make these particles that...

Alan McStravick for redOrbit.com - Your Universe Online In 2004, the pure carbon material known as graphene was isolated by two University of Manchester Nobel Laureates, Andre Geim and Professor Kostya Novoselov, quickly leading to the discovery of a whole new family of one-atom-thick materials. Now researchers from the University of Manchester and National University of Singapore have shown that by building multi-layered heterostructures of graphene in a three-dimensional stack,...
