Physicists find new explanation for key experiment
An experiment at Tohoku University in 2008 laid the foundations for research on 'spin caloritronics' -- a field that aims to develop more effective and energy-saving data processing in information technology. Since then, many new spincaloric effects have been studied, but the key experiment in Japan could not be replicated. Researchers at Bielefeld University's Faculty of Physics have now found an explanation for this.

Tiny carbon-capturing motors may help tackle rising carbon dioxide levels
Machines that are much smaller than the width of a human hair could one day help clean up carbon dioxide pollution in the oceans. Nanoengineers at the University of California, San Diego have designed enzyme-functionalized micromotors that rapidly zoom around in water, remove carbon dioxide and convert it into a usable solid form.

Open-science van der Waals interaction calculations enable mesoscale design and assembly
Scientists at Case Western Reserve University and collaborators at University of Massachusetts-Amherst and University of Missouri-Kansas City, unveil Gecko Hamaker, an open-source computational and modeling tool with a full-spectral optical web-service. Researchers can use this software to calculate van der Waals forces between molecules and meso/nanoscale units, predict molecular organization and evaluate whether new combinations of materials will stick together, thereby facilitating the design of meso/nanoscale self-assembly.

New graphene oxide biosensors may accelerate research of HIV and cancer drugs
Researchers from the Laboratory of Nanooptics and Plasmonics, Moscow Institute of Physics and Technology -- MIPT have devised a novel type of graphene oxide-based biosensor that could potentially significantly speed up the process of drug development. The outstanding properties of this carbon allotrope help to improve significantly the biosensing sensitivity, which in future may enable the development of new drugs and vaccines against many dangerous diseases including HIV, hepatitis and cancer.

Permanent data storage with light
The first all-optical permanent on-chip memory has been developed by scientists of Karlsruhe Institute of Technology and the universities of Münster, Oxford, and Exeter. This is an important step on the way towards optical computers. Phase change materials that change their optical properties depending on the arrangement of the atoms allow for the storage of several bits in a single cell. The researchers present their development in the journal Nature Photonics.

Better trap for greenhouse gases
Researchers around the globe are on a quest for materials capable of capturing and storing greenhouse gases. This shared goal led researchers in Germany and India to team up to explore the feasibility of vertically aligned carbon nanotubes to trap and store two greenhouse gases in particular: carbon dioxide and sulfur dioxide. They report their findings in this week's the Journal of Chemical Physics.

Push to dramatically broaden access to nanotech equipment in the Triangle
The University of North Carolina at Chapel Hill, NC State and Duke are launching a partnership to dramatically broaden access to nanotechnology facilities and expertise to faculty, students, businesses and educators across the Triangle and nationwide. The goal is to encourage both traditional and non-traditional users of these highly specialized and expensive pieces of equipment across the three universities in order to mix ideas and push the limits of innovation.

Physicists defy conventional wisdom to identify ferroelectric material
In a discovery that could open new pathways to find new materials for nanotechnology devices, physicists at the University of Wisconsin and the University of Nebraska-Lincoln found ferroelectricity could be induced in a thin sheet of strontium titanate. The material ordinarily is not ferroelectric. The finding contradicts conventional wisdom that materials lose ferroelectricity as they are made thinner.

Making 3-D objects disappear
Berkeley researchers have devised an ultra-thin invisibility 'skin' cloak that can conform to the shape of an object and conceal it from detection with visible light. Although this cloak is only microscopic in size, the principles behind the technology should enable it to be scaled-up to conceal macroscopic items as well.
