Researchers extend galvanic replacement reactions to metal oxide nanocrystals

(Phys.org) —A large team of researchers, most of which are based in Korea, has succeeded in extending the process of galvanic replacement reactions to ionic compounds. In their paper published in the journal Science, the team describes how they used preformed nanocrystals to serve as a template to produce hollow box-shaped nanocrystals.

Observation of skyrmions in a ferromagnet with centrosymmetry

Researchers from the National Institute of Materials Science (NIMS) have used Lorentz electron microscopy to show that magnetic skyrmions are spontaneously formed as nanomagnetic clusters in a ferromagnetic manganese oxide with centrosymmetry.

Research team finds that the ratio of component atoms vital to performance

There has been great interest in recent years in using tiny particles called quantum dots to produce low-cost, easily manufactured, stable photovoltaic cells. But, so far, the creation of such cells has been limited by the fact that in practice, quantum dots are not as good at conducting an electric charge as they are in theory.

Nano-needles can force medicine into cells, even when they resist taking it

Physicist Pawel Sikorski and his group are making beds of nails on a miniature scale – a plate covered in nano-needles designed to puncture individual cells.

Scientists develop cheaper, more efficient fuel cells

(Phys.org) —Using the Canadian Light Source (CLS) synchrotron, researchers have discovered a way to create cheaper fuel cells by dividing normally expensive platinum metal into nanoparticles (or even single atoms) for use in everything from automobiles to computers.

Researchers manipulate cubic zirconia to improve conductivity in fuel cells

(Phys.org) —Cubic zirconia has long been favored for its use in costume jewelry. Known scientifically as yttria-stabilized zirconia, it is also a known conductor of oxygen, making it useful as an electrolyte in solid oxide fuel cells.

Weird science: Crystals melt when they're cooled

(Phys.org) —Growing thin films out of nanoparticles in ordered, crystalline sheets, to make anything from microelectronic components to solar cells, would be a boon for materials researchers, but the physics is tricky because particles of that size don't form crystals the way individual atoms do.

Novel natural nanomaterial spins off from spider-mite genome sequencing

(Phys.org) —A new, natural nanomaterial, which may prove incredibly beneficial to medical bioengineers, has been discovered by the research team at Western University that successfully sequenced the spider mite genome in 2011.
