Researchers glimpse distortions in atomic structure of materials
Researchers from North Carolina State University are using a technique they developed to observe minute distortions in the atomic structure of complex materials, shedding light on what causes these distortions and opening the door to studies on how such atomic-scale variations can influence a material's properties.

Exotic states materialize with supercomputers
Supercomputers used to find new class of materials that exhibit exotic matter state known as the quantum spin Hall effect. The researchers published their results in the journal Science in December 2014, where they propose a new type of transistor made from these materials. They calculated state-of-the-art first principles approximation method on the XSEDE computational resources Stampede and Lonestar supercomputers of the Texas Advanced Computing Center.

Making teeth tough: Beavers show way to improve our enamel
Beavers don't brush their teeth or drink fluoridated water, but a new Northwestern University study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron. This pigmented enamel, the researchers found, is both harder and more resistant to acid than regular enamel, including that treated with fluoride. This discovery is among others that could lead to a better understanding of human tooth decay, earlier detection of the disease and improving on current fluoride treatments.

Bacterial armor holds clues for self-assembling nanostructures
Berkeley Lab researchers at the Molecular Foundry have uncovered key details in the process by which bacterial proteins self-assemble into a protective coating, like chainmail armor. This process can be a model for the self-assembly of 2-D and 3-D nanostructures.

DNA 'cage' could improve nanopore technology
Researchers from Brown University have designed a tiny cage that can trap a single strand of DNA after it has been pulled through a nanopore. While caged, biochemical experiments can be performed on the strand, which can then be zipped back through the nanopore. The device could enable researchers to look for probe a DNA before and after a reaction takes place.

Buckyballs offer environmental benefits
Treated carbon-60 molecules have the ability to recover valuable metals from liquids, including water and potential pollutants. In testing various metals, Rice University researchers found that charge and ionic radius influence how the metals bind to the hydroxylated buckyballs.

Sodium carbonate capsules used to capture carbon safely
The team developed a new type of carbon capture media composed of core-shell microcapsules, which consist of a highly permeable polymer shell and a fluid (made up of sodium carbonate solution) that reacts with and absorbs carbon dioxide. Sodium carbonate is typically known as the main ingredient in baking soda. The capsules keep the liquid contained inside the core, and allow the CO2 gas to pass back and forth through the capsule shell.

Turing also present at the nanoscale
In the world of single atoms and molecules governed by chaotic fluctuations, is the spontaneous formation of Turing patterns possible -- the same ones that are responsible for the irregular yet periodic shapes of the stripes on zebras' bodies? A Polish-Danish team of physicists has for the first time demonstrated that such a process can not only occur, but can also be used for potentially very interesting applications.

Tiny robotic 'hands' could improve cancer diagnostics, drug delivery
Many people imagine robots today as clunky, metal versions of humans, but scientists are forging new territory in the field of 'soft robotics.' One of the latest advances is a flexible, microscopic hand-like gripper. The development could help doctors perform remotely guided surgical procedures or perform biopsies. The materials also could someday deliver therapeutic drugs to hard-to-reach places. The report appears in the journal ACS Applied Materials & Interfaces.

The tiny particles, hundreds of times smaller than the width of a human hair, were found to exhibit an unexpected variety of shapes, as the physicists from the Technical University Berlin, the University of Rostock, the SLAC National Accelerator Laboratory in the United States and from DESY report in the scientific journal Nature Communications.
