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...

In recent years, metal nanoparticles have showed great application prospect in the field of biological imaging, cancer diagnosis and treatment due to its unique optical scattering and optical absorption properties. In many metal materials, gold nanoparticles have caused concerns in the field because of its simple preparation, easy to modify advantages. However, the poor stability in physiological fluids environment and the potential toxicity of gold nanoparticles always restricts its...

April Flowers for redOrbit.com - Your Universe Online The temperature near the Earth's core is approximately 10,800 degrees Fahrenheit [1] a team of scientists has determined. This is 1,800 degrees hotter than in a previous experiment conducted 20 years prior. The new measurements confirm geophysical models that the temperature difference between the solid core and the mantle above must be at least 1,500 degrees F to explain why the Earth has a magnetic field. The team was even able to...

Deutsches Elektronen-Synchrotron The craft of glassmaking extends way back in time. It was over five-thousand years ago when mankind learned how to make glass. Even prior to this discovery, humans had been using naturally occurring glass for tool making. Despite this long and rich history and widespread use of glass, surprisingly little is known about the interplay between the mechanical properties of glasses and their inner structures. For the first time, researchers from Amsterdam...

Helmholtz Association of German Research Centres In their latest experiment, Prof. Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter at the Hamburg-based Center for Free-Electron Laser Science (CFEL) and Dr. Michael Gensch from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) investigated together with other colleagues from the HZDR, the United Kingdom, and Japan if and how superconductivity can be systematically controlled. The objective of their...

New UEFC-5700 with Auratus(TM) Deposition Process Enhancement Methodology Enables Unprecedented Production Uniformity and Material Collection Efficiency LIVERMORE, Calif., April 2, 2013 /PRNewswire/ -- The Temescal Division of Ferrotec Corporation, a global supplier of materials, components, and precision system solutions and the leading manufacturer of electron beam evaporation systems, today announced the Temescal UEFC-5700, a ultra-high efficiency electron beam metallization...

University of Pennsylvania Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass those limitations, but the components of such computers require semiconductors that can emit light. Now, research from the University of Pennsylvania has enabled "bulk" silicon to emit broad-spectrum, visible light for the first time, opening the possibility...

Syracuse University Ever since their discovery in 1984, the burgeoning area of research looking at quasiperiodic structures has revealed astonishing opportunities in a number of areas of fundamental and applied research, including applications in lasing and sensing. Quasiperiodic structures, or quasicrystals, because of their unique ordering of atoms and a lack of periodicity, possess remarkable crystallographic, physical and optical properties not present in regular crystals. In the...

To engineers, it’s a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current. “The story of electrical conduction in metals is told entirely in terms of electrons.  The cuprates show that there is something completely new to be understood beyond what...
