Research Improves Dry Lubricant Used in Machinery and Biomedical Devices
Engineering researchers at the University of Arkansas treated thin films of polytetrafluoroethylene (PTFE) – a popular polymer used as a dry lubricant for machine components – with silica nanoparticles and found that the filler material significantly reduced wear of the polymer while maintaining a low level of friction. |

DNA-Guided Assembly Yields Novel Ribbon-Like Nanostructures
DNA “linker” strands coax nano-sized rods to line up in way unlike any other spontaneous arrangement of rod-shaped objects. The arrangement—with the rods forming “rungs” on ladder-like ribbons could result in the fabrication of new nanostructured materials with desired properties. |

Zinc: The Goldilocks Metal for Bioabsorbable Stents?
Some materials dissolve too quickly, before cardiac arteries can fully heal, and some hang around forever. Zinc, however, may be just right. |

Microwave Oven Cooks Up Solar Cell Material
University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity. |
