Engineering atomic interfaces for new electronics

For an electron moving from one material toward the other, this space is where it can join other electrons, which together can create current, magnetism or even light. A multi-institutional team has made fundamental discoveries at the border regions, called interfaces, between oxide materials. The team has discovered how to manipulate electrons oxide interfaces by inserting a single layer of atoms. The researchers also have discovered unusual electron behaviors at these engineered interfaces.

Researchers create capacitor effect for magnetricity

Researchers at the London Centre for Nanotechnology have created a purely magnetic version of one of the basic effects of electronics - the storage and release of charge in a capacitor. This follows their demonstration last year of the existence of a magnetic equivalent of electricity: so-called "magnetricity".

Etched quantum dots shape up as single photon emitters

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.

Quantum hot potato: Researchers entice two atoms to swap smallest energy units

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.

Virus-mimicking nanoparticles can stimulate long lasting immunity

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.

New high-performance lithium-ion battery 'top candidate' for electric cars

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.
