World first: Significant development in the understanding of macroscopic quantum behavior
For the first time, the wavelike behavior of a room-temperature polariton condensate has been demonstrated in the laboratory on a macroscopic length scale. This significant development in the understanding and manipulation of quantum objects is the outcome of a collaboration between Professor Stéphane Kéna-Cohen of Polytechnique Montréal, Professor Stefan Maier and research associate Konstantinos Daskalakis of Imperial College London. Their work has been published in the prestigious journal Physical Review Letters.

More precise estimate of Avogadro's number to help redefine kilogram
An ongoing international effort to redefine the kilogram by 2018 has been helped by recent efforts from a team researchers from Italy, Japan and Germany to correlate two of the most precise measurements of Avogadro's number and obtain one averaged value that can be used for future calculations. Their results are published this week in the Journal of Physical and Chemical Reference Data, from AIP Publishing.

Nanoscale light-emitting device has big profile
University of Wisconsin-Madison engineers have created a nanoscale device that can emit light as powerfully as an object 10,000 times its size. It's an advance that could have huge implications for everything from photography to solar power.

Nanowires highly 'anelastic,' research shows
At the nanoscale, familiar materials often take on unexpected properties. Researchers from Brown and NC State have shown that zinc oxide nanowires are highly anelastic, meaning they return to shape slowly after being bent, rather than snapping right back. Anelastic materials are good at dissipating of kinetic energy. This new finding suggest nanowires could be useful in absorbing shocks and vibrations.

Environmentally friendly lignin nanoparticle 'greens' silver nanobullet to battle bacteria
Researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ideas for better, greener and safer nanotechnology and could lead to enhanced efficiency of antimicrobial products used in agriculture and personal care.

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.

Super graphene helps boost chemotherapy treatment
Silver is often used as a coating on medical equipment used for chemotherapy. The problem is that this silver coating can break down drugs. Now, researchers have found a graphene coating that will help boost the effect of chemotherapy.

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.

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.
