Of the 82 technologies selected from among more…

By Ashley Cuff Researchers at the Department of Energy’s Oak Ridge National Laboratory and the University of Tennessee, Knoxville, are advancing gas membrane materials to expand practical technology options for reducing industrial carbon emissions. Results published in Chem demonstrate a fabrication method for membrane materials that can overcome current bottlenecks in selectivity and permeability, key…

trinamiX, a wholly owned subsidiary of BASF, today announced it has developed a new application for its mobile Near-Infrared (NIR) Spectroscopy Solutions to simplify plastic sorting and recycling. Using trinamiX technology, the diverse compositions of different plastics can now be precisely determined and thus distinguished via the simple use of a portable handheld device that…

Southwest Research Institute has developed computer-based techniques to accurately detect crude oil on water using inexpensive thermal and visible cameras. This machine learning-based solution can detect and monitor oil leaks before they become major threats to lakes, rivers and coastal areas. With over 80,000 miles of oil pipelines across the United States, many waterways are…

By Julie Chao   Farmers have enough worries – between bad weather, rising costs, and shifting market demands – without having to stress about the carbon footprint of their operations. But now a new set of projects by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) could make agriculture both more sustainable and more profitable.…
