UT Dallas nanotechnology research leads to super-elastic conducting fibers
A research team based at the University of Texas at Dallas has made electrically conducting fibers that can be reversibly stretched to over 14 times their initial length and whose electrical conductivity increases 200-fold when stretched. In a study published in the July 24 issue of the journal Science, the scientists describe how they constructed the fibers by wrapping electrically conductive sheets of carbon nanotubes to form a jelly-roll-like sheath around a long rubber core.

ORNL researchers make scalable arrays of 'building blocks' for ultrathin electronics
For the first time, researchers at the Department of Energy's Oak Ridge National Laboratory have combined a novel synthesis process with commercial electron-beam lithography techniques to produce arrays of semiconductor junctions in arbitrary patterns within a single, nanometer-thick semiconductor crystal. The process transforms patterned regions of one existing, single-layer crystal into another. The two semiconductor crystals formed sharp junctions, the desired building blocks of electronics. Nature Communications reports the accomplishment.

Simulations lead to design of near-frictionless material
Argonne scientists used the Mira supercomputer to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. ALCF researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code.

An easy, scalable and direct method for synthesizing graphene in silicon microelectronics
Graphene has been studied intensively for its unique properties, and now researchers have developed a microelectronics-compatible method to grow it and have synthesized wafer-scale, high-quality graphene on silicon substrates. The method is based on an ion implantation technique, a process in which ions are accelerated under an electrical field and smashed into a semiconductor. In Applied Physics Letters, the researchers describe their work, which takes graphene a step closer to commercial applications in silicon microelectronics.

Rock paper fungus
Believe it or not: X-ray works a lot better on rocks than on paper. This has been a problem for conservators trying to save historical books and letters. They frankly did not know what they were up against once fungi started to spot the surface of their documents. Now Diwaker Jha, an imaging specialist from Department of Chemistry, University of Copenhagen, has managed to get a first look at how fungus goes about infesting paper.

Rare form: Novel structures built from DNA emerge
Hao Yan, a researcher at Arizona State University's Biodesign Institute, has worked for many years to refine the technique of DNA origami. His aim is to compose new sets of design rules, vastly expanding the range of nanoscale architectures generated by the method. In new research, a variety of innovative nanoforms are described, each displaying unprecedented design control.

Sticky tape and phosphorus the key to ultrathin solar cells: ANU media release
Scientists studying thin layers of phosphorus have found surprising properties that could open the door to ultrathin and ultralight solar cells and LEDs. The team used sticky tape to create single-atom thick layers, termed phosphorene, in the same simple way as the Nobel-prize winning discovery of graphene.

New tool for investigating RNA gone awry
RNA is a fundamental ingredient in all known forms of life -- so when RNA goes awry, a lot can go wrong. A new technology developed by Northwestern University scientists offers the first real-time method to track and observe the dynamics of RNA distribution as it is transported inside living cells. 'Sticky-flares' have the potential to help scientists understand the complexities of RNA better than any analytical technique to date and observe and study the biological and medical significance of RNA misregulation.

Futuristic brain probe allows for wireless control of neurons
A study showed that scientists can wirelessly determine the path a mouse walks with a press of a button. Researchers created a remote controlled, next-generation tissue implant that allows neuroscientists to inject drugs and shine lights on neurons deep inside the brains of mice. The revolutionary device is described online in the journal Cell. Its development was partially funded by the National Institutes of Health.

Device delivers drugs to brain via remote control
Tiny, implantable devices are capable of delivering light or drugs to specific areas of the brain, potentially improving drug delivery to targeted regions of the brain and reducing side effects. Eventually, the devices may be used to treat pain, depression, epilepsy and other neurological disorders in people.

Plantations of nanorods on carpets of graphene capture the Sun's energy
The Sun can be a better chemist, thanks to zinc oxide nanorod arrays grown on a graphene substrate and 'decorated' with dots of cadmium sulphide. In the presence of solar radiation, this combination of zero and one-dimensional semiconductor structures with two-dimensional graphene is a great catalyst for many chemical reactions. The innovative photocatalytic material has been developed by a group of scientists from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw and Fuzhou University in China.

Magnetic nanoparticles could be key to effective immunotherapy
In recent years, researchers have hotly pursued immunotherapy, a promising form of treatment that relies on harnessing and training the body's own immune system to better fight cancer and infection. Now, results of a study led by Johns Hopkins investigators suggests that a device composed of a magnetic column paired with custom-made magnetic nanoparticles may hold a key to bringing immunotherapy into widespread and successful clinical use.

Nanospheres shield chemo drugs, safely release high doses in response to tumor secretions
Scientists coated nanospheres of the anti-cancer drug paclitaxel with a peptide shell that shields the drug as it travels through the circulatory system. When the nanosphere reaches a cancerous tumor, enzymes that enable metastasis slice open the shell to release the drug. The targeted delivery allowed them to safely give mice 16 times the maximum tolerated dose of the clinical formulation of paclitaxel and halted the growth of cancerous tumors.

Constant change
The fundamental constants that govern the laws of nature are being determined with increasing accuracy. A new paper in this week's Journal of Physical and Chemical Reference Data outlines the proceedings from this year's Workshop on the Determination of the Fundamental Constants, where scientists convened to share their research of fundamental constants. Ultimately, better definitions of these constants will aid the redefinition of several standard scientific units, including the kilogram and the Kelvin, by 2018.
