'Molecular accordion' drives thermoelectric behavior in promising material
Engines, laptops and power plants generate waste heat. Thermoelectric materials, which convert temperature gradients to electricity and vice versa, can recover some of that heat and improve energy efficiency. A team of scientists at the Department of Energy's Oak Ridge National Laboratory explored the fundamental physics of the world's best thermoelectric material -- tin selenide -- using neutron scattering and computer simulations. Their work may aid energy sustainability and design of materials that convert heat into electricity.

Nanotechnology inspires next-generation dental materials
Have a cavity? Ask your dentist about filling it with a mixture of nanoparticles including silica and zirconia. These white fillings resemble teeth better than their metal alternatives and are less likely to come loose or fracture teeth. This is just the beginning argue Brazilian scientists in a review of 'nanodentistry,' published Oct. 19 in Trends in Biotechnology. Next-generation dental materials incorporating nanotechnology aim to help teeth self-heal, rebuild enamel, and protect against bacterial infections.

Nanodiamonds might prevent tooth loss after root canals
Nanodiamonds may help patients that have had the dreaded root canal. UCLA dental researchers have developed a nanodiamond-reinforced version of gutta percha, the compound that is used to fill void spaces in dental root canals to prevent infection that can lead to tooth loss. Tested in patient-extracted teeth, the nanodiamond-embedded polymer was substantially stronger than conventional gutta percha. In addition, the scientists tested gutta percha with nanodiamonds that had been loaded with antibiotics and found that the compound effectively prevented bacterial infection.

What are these nanostars in 2-D superconductor supposed to mean?
Physicists from France and Russia have discovered magnetic disturbances in two-dimensional layered superconductors, resembling small oscillating stars. This experimental observation is the direct confirmation of the famous Yu-Shiba-Rusinov theory which predicted an existence of these quantum bound magnetic states. It was found out that in the 2-D systems the magnetic excitations spread over longer distances as compared to ordinary 3-D superconducting materials. Building and manipulating such protected states is a crucial step towards quantum computers.

Researchers take first steps to create biodegradable displays for electronics
Americans, on average, replace their mobile phones every 22 months, junking more than 150 million phones a year in the process. Now,University of Missouri researchers are on the path to creating biodegradable electronics by using organic components in screen displays. The researchers' advancements could one day help reduce electronic waste in the world's landfills.

Patterning oxide nanopillars at the atomic scale by phase transformation
The team, led by Professor Yuichi Ikuhara, at Tohoku University's Advanced Institute for Materials Research has carried out a study aimed at precisely controlling phase transformations with high spatial precision, which represents a significant step forward in realizing new functionalities in confined dimensions. Such a precise control of phase transformations opens up new avenues for materials design and processing, as well as advanced nanodevice fabrication. Full results have been published in Nano Letters.

CWRU researcher lands grant to build stealthy brain tumor treatment
A Case Western Reserve University researcher has received a five-year, $2.82 million National Institutes of Health grant to make chain-like nanoparticles that can carry drugs across the blood-brain barrier to treat glioblastoma multiforme. The nanochains will carry traditional chemotherapy and glioblastoma stem cell inhibitors to destroy the tumor and eliminate cancer cells that are resistant.

One direction: Researchers grow nanocircuitry with semiconducting graphene nanoribbons
Researchers from the University of Wisconsin at Madison are the first to grow self-directed graphene nanoribbons on the surface of the semiconducting material germanium. This allows the semiconducting industry to tailor specific paths for nanocircuitry in their technologies. Confirmation of the findings was done at Argonne's Center for Nanoscale Materials.

New Oregon approach for 'nanohoops' could energize future devices
When the University of Oregon's Ramesh Jasti began making tiny organic circular structures using carbon atoms, the idea was to improve carbon nanotubes for use in electronics or optical devices. Now he believes his technique might roll solo. In a new paper, his team shows that his cycloparaphenylenes can be made using a variety of atoms, not just those from carbon.
