Like snowflakes or fingerprints, no two quantum dots are identical. But a new etching method for shaping and positioning these semiconductor nanocrystals might change that. What's more, tests at the National Institute of Standards and Technology (NIST) confirm that etched quantum dots emit single particles of light (photons), boosting prospects for powering new types of devices for quantum communications.
Physicists at the National Institute of Standards and Technology (NIST) have for the first time coaxed two atoms in separate locations to take turns jiggling back and forth while swapping the smallest measurable units of energy. By directly linking the motions of two physically separated atoms, the technique has the potential to simplify information processing in future quantum computers and simulations.
Scientists at the Emory Vaccine Center have designed tiny nanoparticles that resemble viruses in size and immunological composition and that induce lifelong immunity in mice. They designed the particles to mimic the immune-stimulating effects of one of the most successful vaccines ever developed - the yellow fever vaccine.
Scientists are reporting development of an advanced lithium-ion battery that is ideal for powering the electric vehicles now making their way into dealer showrooms. The new battery can store large amounts of energy in a small space and has a high rate capacity, meaning it can provide current even in extreme temperatures.
Researchers have developed a simple method of making short protein chains with spiral structures that can also dissolve in water, two desirable traits not often found together. Such structures could have applications as building blocks for self-assembling nanostructures and as agents for drug and gene delivery.
The Pittcon 2011 Exposition, which takes place March 14 - 17, at the Georgia World Congress Center, Atlanta, Georgia, will include 978 exhibitors (count as of February 15) that provide products, services, and support for all facets of laboratory operations in the industrial, academic, and government sectors.
Ultrasensitive electronic skin developed by Stanford researcher Zhenan Bao is getting even better. Now she's demonstrated that it can detect chemicals and biological molecules, in addition to sensing an incredibly light touch. And it can now be powered by a new, stretchable solar cell she's developed in her lab, opening up more applications in clothing, robots, prosthetic limbs and more.
The Institute of Nanotechnology (IoN) has just returned from a successful mission to Nanotech 2011 in Tokyo. Together with the Nanotechnology KTN, IoN took key UK SMEs to Japan last week as part of International NanoMicroClub (INMC) initiative.
In an advance that could improve battlefield and trauma care, scientists at Albert Einstein College of Medicine of Yeshiva University have used tiny particles called nanoparticles to improve survival after life-threatening blood loss.
Researchers from Purdue University has reproduced portions of the female breast in a tiny slide-sized model dubbed "breast on-a-chip" that will be used to test nanoparticle-based approaches for the detection and treatment of breast cancer. The model mimics the branching mammary duct system, where most breast cancers begin, and will serve as an "engineered organ" to study the use of nanoparticles to detect and target tumor cells within the ducts.
By replacing a chemical group in the macromolecule, researchers have found a way to bypass RNase and create stable three-dimensional configurations of RNA, greatly expanding the possibilities for RNA in nanotechnology.
