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.

Scientists take the first step toward creating efficient electrolyte-free batteries
Scientists of Peter the Great Saint-Petersburg Polytechnic University (SPbPU) in collaboration with the French, Swiss and Polish researchers have found unique atomic-scale processes in crystal lattice of antiferroelectric lead zirconate during synchrotron x-ray scattering experiment. The discovery is the first step toward creating efficient electrolyte-free accumulators of electric energy. The article 'Critical scattering and incommensurate phase transition in antiferroelectric PbZrO3 under pressure' was published in Scientific Reports of the Nature group.

NUS engineers develop low-cost, flexible terahertz radiation source for fast, non-invasive screening
A research team led by Associate Professor Yang Hyunsoo and Dr. Wu Yang from the NUS Faculty of Engineering and NUS Nanoscience and Nanotechnology Institute has successfully developed flexible, high performance and low-power driven terahertz (THz) emitters that could be mass-produced at low cost. This novel invention is a major technological breakthrough and addresses a critical challenge for industrial application of THz technology.

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.

Researchers in Kiel can control adhesive material remotely with light
Adhesive mechanisms in the natural world have many advantages: they are always strongly adhesive -- and without any glues or residues. Scientists at Kiel University are researching how these mechanisms can be artificially created. An interdisciplinary research team has now succeeded in developing a bioinspired adhesive material that can be controlled remotely by using UV light. This way it is possible to precisely transport objects in a micro-range.

New sensors can detect single protein molecules
For the first time, MIT engineers have designed sensors that can detect single protein molecules as they are secreted by cells. These sensors, which consist of modified carbon nanotubes, could help scientists with any application that requires detecting very small amounts of protein, such as tracking viral infection, monitoring cell manufacture of useful proteins, or revealing food contamination.
