Nanotechnology research has progressed into quantum-level systems where electrons, photonics, and even thermal properties can be engineered, enabling new structures and materials with which to create ever-shrinking, ever-faster electronics.
NanoTech Security Corp. (“NTS”), developer of next-generation security and authentication features using patented nano-optical technologies, today announced that its Chief Executive Officer, Doug Blakeway, will present at the Southwest IDEAS Investor Conference on Thursday, November 21, 2013. The conference is being held at the Sheraton Hotel in Dallas, Texas.
North Carolina State University researchers have a developed a technique for efficiently producing nanoscale gold rods in large quantities while simultaneously controlling the dimensions of the nanorods and their optical properties. The optical properties of gold nanorods make them desirable for use in biomedical applications ranging from imaging technologies to cancer treatment.
Researchers have created tiny holograms using a "metasurface" capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing. The metasurface, thousands of V-shaped nanoantennas formed into an ultrathin gold foil, could make possible "planar photonics" devices and optical switches small enough to be integrated into computer chips for information processing, sensing and telecommunications, said Alexander Kildishev, associate research professor of electrical and computer engineering at Purdue University.
One of the most effective, yet underappreciated, human defence mechanisms relies on antimicrobial peptides - short protein fragments that identify bacteria and disrupt their membrane structure to prevent infection. This in-built defence, virtually untouched by evolution, is now giving scientists clues as to how to create better medicines to combat infection.
Rice University announced today it has established a new academic department to capitalize on the university’s research in materials science and nanotechnology.
The ever-increasing threat from “superbugs” – strains of pathogenic bacteria that are impervious to the antibiotics that subdued their predecessor generations – has forced the medical community to look for bactericidal weapons outside the realm of traditional drugs. One promising candidate is the antimicrobial peptide (AMP), one of Mother Nature’s lesser-known defenses against infections, that kills a pathogen by creating, then expanding, nanometer-sized pores in the cell membrane until it bursts. However, before this phenomenon can be exploited as a medical therapy, researchers need a better understanding of how AMPs and membranes interact at the molecular level.
Gems are known for the beauty of the light that passes through them. But it is the fixed atomic arrangements of these crystals that determine the light frequencies permitted passage.
A research group led by NIMS GREEN and JST, in collaboration with WPI-MANA and the Synchrotron X-ray Station at SPring-8, developed a new measurement system using high-energy X-rays of SPring-8 and a Si thin-membrane window.
Assistant Professor of Physics Nathan Lindquist has been awarded a $252,393 grant from the National Science Foundation (NSF) for his project, “Super-resolution plasmon-enhanced imaging and spectroscopy with patterned metallic surfaces and dynamic illumination.”
