  • House cleaning on the nanoscale

    A team of scientists at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) has developed a novel mechanical cleaning method for surfaces on the nanoscale. The technique successfully removes even the tiniest contaminants down to the atomic scale, achieving an unprecedented level of cleanliness. more

  • A possible end to 'forever' chemicals

    Synthetic chemicals known as per- and polyfluoroalkyls, or PFAS, contain bonds between carbon and fluorine atoms considered the strongest in organic chemistry. Unfortunately, the widespread use of these nonbiodegradable products since the 1940s has contaminated many water supplies across America. En more

  • The Secret Contamination of Polar Bears

    Using a new approach to measure chemical contaminants in polar bears, scientists from Canada and the United States found a large variety of new chlorinated and fluorinated substances, including many new polychlorinated biphenyl metabolites. Worryingly, these previously unrecognized contaminants have more

  • The Secret of Bearing Lubrication

    At the heart of almost every industrial facility are electric motors, which can render equipment inoperative should their rolling element bearings fail-an occurrence more common than necessary due to strain resulting from improper lubrication more

  • Best Practices to Mitigate Lubricant Contamination

    Many assume the contamination of lubricants occurs after the lubricants have been applied to machines. While wear debris and water ingress are expected to contribute to lubricant contamination it doesn't mean maintenance professionals need to accept more

  • GC-C-IRMS Determination of Hormones

    By amending methodology to utilize eVol® for sample preparation processes for GC-C-IRMS C isotope ratio analysis, the ISORA department has: improved sample preparation conditions and the GC-C-IRMS analysis results by removing the risk of ghost peaks, more
