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.

New technique enables magnetic patterns to be mapped in 3-D
An international collaboration has succeeded in using synchrotron light to detect and record the complex 3-D magnetization in wound magnetic layers. 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.

Tel Aviv/Tsinghua University project uses crowd computing to improve water filtration
A joint research project by Tel Aviv University and Tsinghua University proposes a novel nanotechnology-based strategy to improve water filtration. The project, initiated by IBM's World Community Grid, was an experiment in crowdsourced computing -- carried out by over 150,000 volunteers who contributed their own computing power to the research.

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.

NIST 'how-to' website documents procedures for nano-EHS research and testing
As engineered nanomaterials increasingly find their way into commercial products, researchers who study the potential environmental or health impacts of those materials face a growing challenge to accurately measure and characterize them. These challenges affect measurements of basic chemical and physical properties as well as toxicology assessments. To help nano-EHS (Environment, Health and Safety) researchers navigate the often complex measurement issues, NIST has launched a new website devoted to validated laboratory protocols for nano-EHS studies.

Ultra-stable JILA microscopy technique tracks tiny objects for hours
JILA researchers have designed a microscope instrument so stable that it can accurately measure the 3-D movement of individual molecules over many hours -- hundreds of times longer than the current limit measured in seconds. The technology was designed to track the machinery of biological cells, down to the tiniest bits of DNA, a single 'base pair' of nucleotides among the 3 billion of these chemical units in human genes. But the instrument could be useful well beyond biology, biochemistry and biophysics, perhaps in manufacturing.

Drexel's microscale 'Transformers' are joining forces to break through blocked arteries
Swarms of microscopic, magnetic, robotic beads could be scrubbing in next to the world's top vascular surgeons -- all taking aim at blocked arteries. These microrobots, which look and move like corkscrew-shaped bacteria, are being developed by mechanical engineers at Drexel University as a part of a surgical toolkit being assembled by the Daegu Gyeongbuk Institute of Science and Technology in South Korea.

Effective conversion of methane by a new copper zeolite
A new bio-inspired zeolite catalyst, developed by an international team with researchers from Technische Universität München, Eindhoven University of Technology and University of Amsterdam, might pave the way to small scale 'gas-to-liquid' technologies converting natural gas to fuels and starting materials for the chemical industry. Investigating the mechanism of the selective oxidation of methane to methanol they identified a trinuclear copper-oxo-cluster as the active center inside the zeolite micropores.
