RED BANK, N.J., Nov. 11, 2010 /PRNewswire/ -- The research program of Natcore Technology Inc. (TSX-V: NXT; NTCXF.PK) being conducted by Natcore scientists working at Rice University under the direction of Prof. Andrew Barron has successfully formed a multilayered array of silicon quantum dots embedded in a silicon dioxide matrix. Grown using the liquid phase deposition (LPD) process developed at Rice and exclusively licensed to Natcore, the array is comprised of silicon quantum dots with...
Researchers at the University at Buffalo have developed a novel technology using quantum dots that is expected to have major implications for research and treatment of tuberculosis, as well as other inflammatory lung diseases.A paper appearing online in Nanomedicine: Nanotechnology, Biology and Medicine as an article-in-press describes specific delivery of a chemotherapeutic drug to specific cells in the lung, particularly the alveolar white cell, without causing acute inflammation.Quantum...
Discovery advances novel devicesChinese researchers, reporting in the Journal of Applied Physics, published by the American Institute of Physics, have described a new breakthrough in understanding the way electrons travel around quantum dots. This might lead to promising new fabrication methods of novel quantum devices.Guodong Li and colleagues at the National Center for Nanoscience and Technology in Beijing carried out an experiment using self-assembled quantum dots and a two-dimensional...
Getting an inside look at the center of a cell can be as easy as a needle prick, thanks to University of Illinois researchers who have developed a tiny needle to deliver a shot right to a cell's nucleus.Understanding the processes inside the nucleus of a cell, which houses DNA and is the site for transcribing genes, could lead to greater comprehension of genetics and the factors that regulate expression. Scientists have used proteins or dyes to track activity in the nucleus, but those can be...
An international research group led by scientists from the University of Bristol has developed a new approach to quantum computing that could soon be used to perform complex calculations that cannot be done by today's computers.Scientists from Bristol's Centre for Quantum Photonics have developed a silicon chip that could be used to perform complex calculations and simulations using quantum particles in the near future. The researchers believe that their device represents a new route to a...
The PhD thesis by Carlos EcheverrÃa Arrondo, Doctor in Physics from the Public University of Navarre and entitled "On doped semiconductor quantum dots and magnetic nanowires", studied the behaviour and properties of nanometric-scale semiconductor crystals.The interest aroused by nanoscience and nanotechnology spurred Dr EcheverrÃa to study the behaviour of semiconductor crystals when their size is reduced to less than one hundred nanometres (a nanometre is a millionth part of a...
Tokyo, Sept 10, 2010 - (JCN Newswire) - Institute for Nano Quantum Information Electronics, The University of Tokyo (Director: Yasuhiko Arakawa), Fujitsu Laboratories Limited, and NEC Corporation today announced that they have achieved quantum cryptographic key distribution(1) at a world-record distance of 50 km using transmission from a single-photon emitter(2). This result was the product of the three-way collaboration between the University of Tokyo, Fujitsu,...
Researchers from North Carolina State University have developed extremely small microneedles that can be used to deliver medically-relevant nanoscale dyes called quantum dots into skin "“ an advance that opens the door to new techniques for diagnosing and treating a variety of medical conditions, including skin cancer."We were able to fabricate hollow, plastic microneedles using a laser-based rapid-prototyping approach," says Dr. Roger Narayan, one of the lead researchers, "and found that...
Breakthrough discovery enables nanoscale manipulation of the piezoelectric effectThe generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers at McGill University's Department of Chemistry have now discovered how to control this effect in nanoscale semiconductors called "quantum...
A new paper by University of Notre Dame physicist Boldizsár Jankó and colleagues offers an important new understanding of an enduring mystery in chemical physics.More than a century ago, at the dawn of modern quantum mechanics, the Noble Prize-winning physicist Neils Bohr predicted so-called "quantum jumps." He predicted that these jumps would be due to electrons making transitions between discrete energy levels of individual atoms and molecules. Although controversial in...
