Rotational X-ray tracking uncovers hidden motion at the nanoscale
Over the past two decades or so, there has been increasing interest and development in measuring slow dynamics in disordered systems at the nanoscale, brought about in part from a demand for advancements in the food and consumer products industries.

Bioprinting a 3D liver-like device to detoxify the blood
Nanoengineers at the University of California, San Diego have developed a 3-D-printed device inspired by the liver to remove dangerous toxins from the blood. The device, which is designed to be used outside the body -- much like dialysis -- uses nanoparticles to trap pore-forming toxins that can damage cellular membranes and are a key factor in illnesses that result from animal bites and stings, and bacterial infections. Their findings were published May 8 in the journal Nature Communications.

Recycling the next generation
About 70 billion tons of raw materials are extracted world wide annually. That is twice as much as at the end of the 1970s. This trend is continuing -- even with finite resources. One way to have enough materials available for manufacturing new goods in future is to recycle continually. Fraunhofer researchers are working on the advanced 'Molecular Sorting' project for the next-generation circular economy.

Scientists create first living organism that transmits added letters in DNA 'alphabet'
Scientists at The Scripps Research Institute have engineered a bacterium whose genetic material includes an added pair of DNA 'letters,' or bases, not found in nature. The cells of this unique bacterium can replicate the unnatural DNA bases more or less normally, for as long as the molecular building blocks are supplied.

Discovery offers new possibilities for clean energy research
University of Houston physicists have discovered a new thermoelectric material offering high performance at temperatures ranging from room temperature up to 300 degrees Celsius, or about 573 degrees Fahrenheit. Zhifeng Ren, M.D. Anderson Chair professor of physics at UH and the lead author of a paper describing the discovery, published online by Nano Energy, said the work could be important for clean energy research and commercialization at temperatures of about 300 degrees Celsius.

Graphene for real-world devices
Graphene is an excellent conductor of electricity and heat, but a number of practical challenges must be overcome before it can emerge as a replacement for silicon. University of Texas professor Li Shi is exploring novel ways of supporting and connecting graphene using experimental and computational methods. Using the Stampede supercomputer, Shi inferred how phonons (the vibrations of atoms in solids) scatter as a function of the thickness of graphene layers.

Smaller microchips that keep their cool
Temperatures often over 200 degrees C occur in geothermal and oil production -- conventional microelectronics hit their limits there. Researchers have now fabricated compact microchips that can keep their cool even at 300 degrees C.

Taking the lead out of a promising solar cell
Northwestern University researchers are the first to develop a solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using 'bench' chemistry -- no fancy equipment or hazardous materials. Perovskite solar cells are being touted as the 'next big thing in photovoltaics.' Lead perovskite has achieved 15 percent efficiency, and tin perovskite should be able to match -- and possibly surpass -- that.

Researchers find the accelerator for molecular machines
How hard can it be to make a wheel rotate in a machine? Very hard actually, when the wheel sits in one of those nano-small molecular machines that are predicted to be running our future machines. But before the molecular machines become part of our daily lives, researchers must be able to control them. A Danish/American research team have now solved part of this problem.

New revolutionary sensor links pressure to color change
A high-resolution pressure sensor developed at the University of California, Riverside indicates pressure by varying its color -- a sensor that all of us can use with just our eyes. This sensor differs from commercially available pressure sensor films. The new technology produces a mosaic of easy-to-distinguish colors and has the benefit of higher contrast and resolution. It can potentially be used in many safety devices for revealing pressure distribution over even very complex surfaces.

Harnessing magnetic vortices for making nanoscale antennas
Scientists seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics have published a study showing that stacked nanoscale magnetic vortices separated by an extremely thin layer of copper can be driven to operate in unison. These devices could potentially produce a powerful signal that could be put to work in a new generation of cell phones, computers, and other applications.

New lab-on-a-chip device overcomes miniaturization problems
UNSW Australia chemists have invented a new type of tiny lab-on-a-chip device that could have a diverse range of applications, including to detect toxic gases, fabricate integrated circuits and screen biological molecules. The novel technique developed by the team involves printing a pattern of miniscule droplets of a non-volatile solvent -- an ionic liquid -- onto a gold-coated or glass surface. The results are published in the journal Nature Communications.

Brain tumor cells penetrated by tiny, degradable particles carrying genetic instructions
Working together, Johns Hopkins biomedical engineers and neurosurgeons report that they have created tiny, biodegradable 'nanoparticles' able to carry DNA to brain cancer cells in mice. The team says the results of their proof of principle experiment suggest that such particles loaded with 'death genes' might one day be given to brain cancer patients during neurosurgery to selectively kill off any remaining tumor cells without damaging normal brain tissue.
