Nanomachines: Pirouetting in the spotlight
Scientists from Ludwig-Maximilians-Universitaet in Munich have developed a new class of molecular motors that rotate unidirectionally at speeds of up to 1 kHz when exposed to sunlight at room temperature. This unique combination of features opens up novel applications in nano-engineering.

Physicists map the strain, pixel by pixel, in wonder material graphene
In a study published in Nature, a team of scientists map the strain in graphene, a 2-D sheet of carbon that is strong, flexible and can expand without breaking. Though the material has found its way into several applications, ranging from tennis rackets to smartphone touch screens, several obstacles are holding up further commercialization of graphene. One of these is the presence of defects that impose strain on graphene's lattice structure and adversely affects its electronic and optical properties.

Researchers disguise drugs as platelets to target cancer
Researchers have for the first time developed a technique that coats anticancer drugs in membranes made from a patient's own platelets, allowing the drugs to last longer in the body and attack both primary cancer tumors and the circulating tumor cells that can cause a cancer to metastasize. The work was tested successfully in an animal model.

New processes in modern ReRAM memory cells decoded
Resistive memory cells or ReRAMs for short are deemed to be the new super information-storage solution of the future. At present, two basic concepts are being pursued, which, up to now, were associated with different types of active ions. But this is not quite correct, as Jülich researchers working together with their Korean, Japanese and American colleagues were surprised to discover. The effect enables switching characteristics to be modified as required.

Hopes of improved brain implants
Neurons thrive and grow in a new type of nanowire material developed by researchers in Nanophysics and Ophthalmology at Lund University in Sweden. In time, the results might improve both neural and retinal implants, and reduce the risk of them losing their effectiveness over time, which is currently a problem.

Zenyatta Albany graphite has unique properties for graphene applications
According to Dr. Regev, 'Thermogravimetric Analysis on the material found it to be completely different from any other natural graphite flake products studied so far in our lab. The Zenyatta graphite appears to be composed of smaller and cleaner particles with a narrower particle size distribution. It is the same order of magnitude as more expensive, commercially available Graphene Nano Platelets. These ideal properties probably stem from the unique geological process by which the Albany graphite deposit was formed.'

Los Alamos explores hybrid ultrasmall gold nanocluster for enzymatic fuel cells
With fossil-fuel sources dwindling, better biofuel cell design is a strong candidate in the energy field. In research published in the Journal of the American Chemical Society, Los Alamos researchers and external collaborators synthesized and characterized a new DNA-templated gold nanocluster (AuNC) that could resolve a critical methodological barrier for efficient biofuel cell design.

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.
