October Chementator Briefs

By Edited by Gerald Ondrey |

  Flexible aerogels Researchers at the NASA Glenn Research Center (Cleveland, Ohio; www.nasa.gov) have developed new flexible aerogels that could eventually be used in highly insulating materials and linings. Aerogels, sometimes called “solid smoke,” are superlightweight structures of silica reinforced with polymer to add flexibility. Traditional silica aerogels were brittle, and crumbled easily. Another type of aerogel was made from polyimide, a strong and heat-resistant polymer, braced with cross-links for added strength. The work was presented at the recent meeting of the American Chemical Society (ACS; Washington, D.C.; www.acs.org) in Philadelphia. HART enhancements Last month, the HART Communication Foundation (Austin, Tex.; www.hartcomm.org) unveiled five new enhancements to the HART Communication Protocol standard. When implemented in new HART-enabled products, these enhancements will give users a simple device-status notfication and easy access to Wireless HART network performance. The new enhancements are: Condensed Device Status Indicators, which provide new commands and standardized support for Namur NE107 diagnostics for operator notification of failure, out of specification, function check or maintenance…
