Using DNA not as a genetic material but as a structural support, Cornell researchers have created thin sheets of gold nanoparticles held together by strands of DNA. The work could prove useful for making thin transistors or other electronic devices.
The U.S. Department of Defense announced May 8 that a Cornell team led by professor of electrical and computer engineering Michael Spencer will share a $1.5 million, five-year grant from the Air Force Office of Scientific Research to fabricate graphene, a one-atom thick layer of carbon, in large sheets suitable for use in microchips.
An interdisciplinary team of researchers at Brigham and Women's Hospital and the Harvard-MIT Division of Health Sciences and Technology has demonstrated a better way to deliver cancer drugs directly to tumors by using specially engineered nanoparticles that can inhibit a signaling pathway and deliver a higher concentration of medication to the specific area.
A seminar titled 'Nano and Environment: Where to look for the nano-needle in the environmental haystack?' today at the Institute for NanoBioTechnology at Johns Hopkins deals with the environmental impacts of nanomaterials.
Researchers have developed a new nickel-tungsten alloy that is not only safer than chrome but also more durable. The new coating, which is now being tested on the bumpers of a truck fleet, could also replace chrome in faucet fixtures and engine parts, among other applications.
After getting rapped by President Dmitry Medvedev earlier this month, the State Nanotechnology Corporation was once again criticized by a top government official on Tuesday, as Deputy Prime Minister Sergei Ivanov accused the company of 'lagging behind' in realizing its goals.
Aerosol delivery of antibiotics via nanoparticles may provide a means to improve drug delivery and increase patient compliance, thus reducing the severity of individual illnesses, the spread of epidemics, and possibly even retarding antibiotic resistance.
The 1D Heterostructure Tool is a program for the design and simulation of 1D heterostructures. It currently implements the effective mass bandstructure model and parameters for materials belonging to GaAs substrate such as GaP, InAs, AlGaAs etc.
In Metamaterials, Professor Munk, a leading expert on periodic structures, denies the existence of negative refraction and provides convincing alternative explanations involving surface waves to some of the experimental examples of metamaterials in the literature.
