Nature Nanotechnology
Researchers find nanowires have unusually pronounced 'anelastic' properties
Researchers from North Carolina State University and Brown University have found that nanoscale wires (nanowires) made of common semiconductor materials have a pronounced anelasticity -- meaning that the wires, when bent, return slowly to their original shape rather than snapping back quickly.

Graphene-based film can be used for efficient cooling of electronics
Researchers at Chalmers University of Technology have developed a method for efficiently cooling electronics using graphene-based film. The film has a thermal conductivity capacity that is four times that of copper. Moreover, the graphene film is attachable to electronic components made of silicon, which favours the film's performance compared to typical graphene characteristics shown in previous, similar experiments.

Graphene gets competition
Graphene, the only one atom thick carbon network, achieved overnight fame with the 2010 Nobel Prize. But now comes competition: such layers can also be formed by black phosphorous. Chemists at the Technische Universität München have now developed a semiconducting material in which individual phosphorus atoms are replaced by arsenic. In a collaborative international effort, American colleagues have built the first field-effect transistors from the new material.

Tunneling out of the surface
A new chemical reaction pathway on titanium dioxide has been discovered. The reaction mechanism involves the application of an electric field that narrows the width of the reaction barrier, thereby allowing hydrogen atoms to tunnel away from the surface. This opens the way for the manipulation of the atomic-scale transport channels of hydrogen, which could be important in hydrogen storage.

Tapping the full innovation potential of research
As many as four fundamental research ideas of KIT convinced the European Research Council. The leading researchers will now be granted nearly 150,000 euros in addition to tap the full innovative potential of their results. The so-called 'Proof of Concept Grants' serve to further develop application-relevant research results for the market. The four projects focus on the analysis of biological samples, data transmission, and the microstructuring of materials.

Ultra-thin, all-inorganic molecular nanowires successfully compounded
The development of metal oxide-based molecular wires is important for fundamental research and potential practical applications. However, examples of these materials are rare. Researchers from Hokkaido University, Kanagawa University, Hiroshima University and Japan Synchrotron Radiation Research Institute/SPring-8, Japan, successfully created ultrathin all-inorganic molecular nanowires, composed of a repeating hexagonal molecular unit made of Mo and Te; the diameters of these wires were only 1.2 nm.

Bats do it, dolphins do it -- now humans can do it, too
Bats have been using sonar to navigate and communicate for ages, and now humans can do the same, thanks to lightweight and efficient ultrasound microphones and loudspeakers developed by UC Berkeley physicists. The devices owe their flat frequency response to graphene, which makes a stiff and responsive diaphragm far superior to those in today's ultrasound receivers and transmitters. Biologists can even slap one on a bat to record its nightly ultrasonic conversations.

Down to the quantum dot
Using a single molecule as a sensor, scientists in Jülich have successfully imaged electric potential fields with unrivaled precision. The ultrahigh-resolution images provide information on the distribution of charges in the electron shells of single molecules and even atoms. The 3-D technique is also contact-free. The first results achieved using 'scanning quantum dot microscopy' have been published as an editor's suggestion in Physical Review Letters and selected as a Viewpoint in Physics.

This technique could be important in the development of devices that are highly sensitive to magnetic fields, such as in medical diagnostics for example. Their results are published now in Nature Communications.

A cool way to form 2-D conducting polymers using ice
Chemists at Pohang University of Science and Technology, Korea, have discovered an innovative method to form two-dimensional polyaniline (PANI) nanosheets using ice as a hard template. The product, called PANI-ICE, is reported to have distinctly outstanding electrical properties of low resistivity and high conductivity. PANI-ICE nanosheets show high electronic current flows twice as high as that of graphene and over 40 times higher conductivity of PANI materials produced by existing established synthetic procedures.

Could black phosphorus be the next silicon?
In a study published in Nature Communications, researchers from McGill University and Université de Montréal report that when electrons move in a phosphorus transistor, they do so only in two dimensions. The finding suggests that black phosphorus could help engineers surmount one of the big challenges for future electronics: designing energy-efficient transistors.

Surfing a wake of light
For the first time, Harvard researchers have created wakes of light-like waves moving on a metallic surface, called surface plasmons, and demonstrated that they can be controlled and steered. The creation and control of surface plasmon wakes could lead to new types of plasmonic couplers and lenses that could create two-dimensional holograms or focus light at the nanoscale.

Launch of first European nanomedicine characterization lab
Empa, the Swiss Federal Laboratories for Materials Science and Technology, is part of the collaborative 'European Nanomedicine Characterization Laboratory,' a European project funded by the EU framework program 'Horizon 2020.' Its goal is to reach a level of international excellence in nanomedicine characterization for diseases like cancer, diabetes, inflammatory diseases or infections. This competence will be made accessible to all organizations developing candidate nanomedicines prior to their submission to regulatory agencies to get approval for clinical trials and, later on, for marketing authorization.

Nanospiked bacteria are the brightest hard X-ray emitters
In a scientific breakthrough, researchers at the Tata Institute of Fundamental Research, Mumbai and Institute for Plasma Research, Gandhi Nagar have fashioned bacteria to emit intense, hard X-ray radiation. Published in Optics Express this month, they show that irradiating a glass slide coated with nanoparticle doped bacteria, turns the cellular material into hot, dense plasma, making this a useful table top X-ray source with several potential applications.
