  • Nanomaterial safety on a nano budget

    True Viral News , 9th Jun 2019

    “There was a series of studies that said if you’re going to handle nanotubes, you really need to use safety protocols,” Barron said. “Then I saw a study that said many labs didn’t use any form of hood or containment system. In the U.S., it was really bad, and in Asia it was even worse. But there are a significant number of labs scaling up to use these materials at the kilogram scale without taking the proper precautions.”

  • Nanomaterial safety on a nano budget

    Chem Europe , 5th Jun 2019

    The Rice University lab of chemist Andrew Barron works with bulk carbon nanotubes on a variety of projects. Years ago, members of the lab became concerned that nanotubes could escape into the air, and developed a cheap and clean method to keep them contained as they were transferred from large containers into jars for experimental use.

    More recently Barron himself became concerned that too few labs around the world were employing best practices to handle nanomaterials. He decided to share what his Rice team had learned.

  • Rice Scientists Present Their Protocol for Carbon Nanotube Handling

    AZoNano , 4th Jun 2019

    The lab’s low-cost technique is explained in full in an open-access paper in the Springer Nature journal SN Applied Sciences.

    Carbon nanotubes, in bulk form, are fluffy and scatter easily if disturbed. The Rice lab usually stores the tubes in 5-gallon plastic buckets, and merely opening the lid is sufficient to cause them to fly due to their low density.

  • Nanomaterial safety on a nano budget

    EurekAlert! , 3rd Jun 2019

    Full details are available in the paper, but the precautions include making sure workers are properly attired with long pants, long sleeves, lab coats, full goggles and face masks, along with two pairs of gloves duct-taped to the lab coat sleeves. The improvised glove bag involves a 25-gallon trash bin with a plastic bag taped to the rim. The unopened storage container is placed inside, and then the bin is covered with another transparent trash bag, with small holes cut in the top for access.

  • A novel EOR surfactant

    The Chemical Engineer , 13th May 2019

    Scientists at Swansea University, UK have developed a novel, ‘green’ surfactant which improves oil recovery by 72%. The surfactant is quick and simple to synthesise and could provide a cheaper, greener alternative to common EOR surfactants.
