Nature Physics
A direct look at graphene
Berkeley Lab researchers have recorded the first direct observations at microscopic lengths of how electrons and holes respond to a charged impurity in graphene. The results point to interactions between electrons as being critical to graphene's extraordinary properties.

Reluctant electrons enable 'extraordinarily strong' negative refraction
Researchers at the Harvard School of Engineering and Applied Sciences have demonstrated a drastically new way of achieving negative refraction in a metamaterial. The advance, reported in the Aug. 2 issue of Nature, results in an "extraordinarily strong" negative refractive index as large as -700, more than a hundred times larger than most previously reported.

A giant step in a miniature world: UZH researcher measures the electrical charge of nano particles
Nano particles are a millionth of a millimeter in size, making them invisible to the human eye. Unless, that is, they are under the microscope of Prof. Madhavi Krishnan, a biophysicist at the University of Zurich. Prof. Krishnan has developed a new method that measures not only the size of the particles but also their electrostatic charge. Up until now it has not been possible to determine the charge of the particles directly.

Breakthrough by U of T-led research team leads to record efficiency for next-generation solar cells
Researchers from the University of Toronto (U of T) and King Abdullah University of Science & Technology (KAUST) have made a breakthrough in the development of colloidal quantum dot (CQD) films, leading to the most efficient CQD solar cell ever. Their work is featured in a letter published in Nature Nanotechnology. The researchers, led by U of T Engineering Professor Ted Sargent, created a solar cell out of inexpensive materials that was certified at a world-record 7.0 percent efficiency.

UK research paves way to a scalable device for quantum information processing
Researchers at NPL have demonstrated for the first time a monolithic 3D ion microtrap array which could be scaled up to handle several tens of ion-based quantum bits. The research, published in Nature Nanotechnology, shows how it is possible to realize this device embedded in a semiconductor chip, and demonstrates the device's ability to confine individual ions at the nanoscale.

Radiation damage bigger problem in microelectronics than previously thought
The amount of damage that radiation causes in electronic materials may be at least 10 times greater than previously thought. That is the surprising result of a new characterization method that uses a combination of lasers and acoustic waves to that allows scientists to peer through solid materials to pinpoint the size and location of detects buried deep inside with unprecedented precision.

Modifying surfaces by means of nanostructured reliefs to prevent the spread of bacteria
Researchers at the Agrobiotechnology Institute of Navarre are designing nanostructured reliefs on surfaces. The idea is to enable these surfaces to acquire antibacterial properties and make them more resistant to the formation of bacterial biofilms. The authors of the research say that in the preliminary tests carried out so far with the bacteria Staphylococcus aureus a reduction in the region of 65-70 percent has been confirmed in the adhesion of bacteria.

UGA researchers develop rapid diagnostic test for pathogens, contaminants
Using nanoscale materials, researchers at the University of Georgia have developed a single-step method to rapidly and accurately detect viruses, bacteria and chemical contaminants. The scientists were able to detect compounds such as lactic acid and albumin in highly diluted samples and in mixtures that included dyes and other chemicals. Their results suggest the same system could be used to detect pathogens and contaminants in biological mixtures such as food, blood, saliva and urine.

World record: Scientists from northern Germany produce the lightest material in the world
A network of porous carbon tubes that is three-dimensionally interwoven at nano and micro level this is the lightest material in the world. It weights only 0.2 milligrams per cubic centimeter, and is therefore 75 times lighter than Styrofoam, but it is very strong nevertheless. Scientists of Kiel University and Hamburg University of Technology have named their joint creation "aerographite."
