Proceedings of the National Academy of Sciences
Surprising spin behavior at room temperature
Scientists at Tokyo Institute of Technology have observed almost purely circularly polarized electroluminescence from GaAs-based spin-polarized light-emitting diodes at room temperature, with no external magnetic field. This behavior indicates the presence of spin-dependent nonlinear processes, which may allow the development of semiconductor-based spin-photonic devices in the future.

Monell Center receives grant to characterize distinctive odor of ovarian cancer
A new three-year $815,000 grant to the Monell Center from the Robert J. Kleberg, Jr. and Helen C. Kleberg Foundation will allow Monell scientists and collaborators to confirm initial findings of a unique odor pattern, known as an odor signature, for ovarian cancer. The multi-disciplinary team will utilize the odor information to customize a portable screening device that can diagnose the deadly disease at early, treatable stages.

Supercomputing, experiment combine for first look at magnetism of real nanoparticle
A multi-institution team simulated, for the first time, atomic-level magnetic properties in regions of a real nanoparticle based on experimental data. UCLA and Berkeley Lab's cutting-edge imaging and 3-D reconstruction techniques combined with the 27-petaflop Titan supercomputer at OLCF and the award-winning LSMS magnetic structure code, developed at ORNL, enabled researchers to model the magnetic properties of over a thousand atoms of an iron-platinum nanoparticle -- a material that has applications for next-generation magnetic storage devices.

Three magnetic states for each hole
Nanometer-scale magnetic perforated grids could create new possibilities for Computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ('antidot') three magnetic states can be configured.

1,000 times more efficient nano-LED opens door to faster microchips
The electronic data connections within microchips are increasingly becoming a bottleneck in the exponential growth of data traffic. Optical connections are the obvious successors but optical data transmission requires an adequate nanoscale light source, and this has been lacking. Scientists at Eindhoven University of Technology have created a light source that has the right characteristics: a nano-LED that is 1,000 times more efficient than its predecessors, and is capable of handling gigabits per second.

Thin, flexible, light-absorbent material for energy and stealth applications
Transparent window coatings that keep buildings and cars cool on sunny days. Devices that could more than triple solar cell efficiencies. Thin, lightweight shields that block thermal detection. These are potential applications for a thin, flexible, light-absorbing material developed by engineers at the University of California San Diego.

Physical Review X
Quantum phase transition observed for the first time
A group of scientists led by Johannes Fink from the Institute of Science and Technology Austria reported the first experimental observation of a first-order phase transition in a dissipative quantum system. Phase transitions are something we often encounter in everyday life, for example when watching the freezing of water. But they also occur at the quantum mechanical level, where they are -- in spite of their importance for various fields of physics -- relatively unexplored.

Artificially introduced atomic-level sensors enable measurements of the electric field within a working semiconductor device
Researchers develop a method for sensing the electric field generated in semiconductor devices during operation. The technique is demonstrated for a diamond device, with nitrogen-vacancy centers acting as local electric-field probes, subject to bias voltages up to 150 volt.

The shape of melting in two dimensions
As part of her team's research into matter's tendency to self-organize, Sharon Glotzer of the University of Michigan ran a series of hard particle simulations to study melting in two-dimensional (2-D) systems. Specifically, the team explored how particle shape affects the physics of a 2-D solid-to-fluid melting transition.

Background suppression for super-resolution light microscopy
Researchers of Karlsruhe Institute of Technology have developed a new fluorescence microscopy method: STEDD (Stimulation Emission Double Depletion) nanoscopy produces images of highest resolution with suppressed background. The new method yields an enhanced image quality, which is advantageous when analyzing three-dimensional, densely arranged subcellular structures. STEDD, a further development of the STED method, is now presented in Nature Photonics.

Highly sensitive gas sensors for volatile organic compound detection
A collaboration of researchers in Japan has developed a sensor for volatile organic compound (VOC) detection. Their manufacturing method allows for fine-tuning of SnO2 nanocrystal and pore sizes. Experiments found that a dramatic increase in sensitivity was realized by Pd-loading the sensors. The highly sensitive devices may have a practical use detecting specific biomarkers for medical diagnostics.

UCLA physicists map the atomic structure of an alloy
UCLA physicists and collaborators have mapped the coordinates of more than 23,000 individual atoms in a tiny iron-platinum nanoparticle to reveal the material's innate defects. These results demonstrate that the positions of tens of thousands of atoms can be precisely identified and then fed into quantum mechanics calculations to correlate imperfections and defects with material properties at the single-atom level.

Understanding breakups
As interest and demand for nanotechnology continues to rise, so will the need for nanoscale printing and spraying, which relies on depositing tiny drops of liquid onto a surface. Now researchers from Tsinghua University in Beijing have developed a new theory that describes how such a nanosized droplet deforms and breaks up when it strikes a surface.
