  • NeSSI’s success should be a lock

    The New Sampling/Sensor Initiative or NeSSI that replaces tubing, fittings and other hardware in a sampling system with miniature modular components makes sense. Enhancements now in the works should assure its success.

  • Avoid trouble with slurries

    Handling slurries (a mix of solids and liquids), should be based on experience and experiments, not theory. Much of the knowledge obtained from pneumatic conveyors and fluidization systems can be used in understanding slurries.

  • Rethink experiment design

    The traditional approach to experimentation, often referred to as the “scientific method,” requires changing only one factor at a time (OFAT), but this method only allows one to see things one dimension at a time. By varying factors only at two levels each, but simultaneously rather than one at a time, experimenters can uncover important interactions.

  • Industry tackles a grave issue

    End-of-life and other product stewardship initiatives will impact chemical plants. An agreement to lessen the environmental impact of chemicals production will have global ramifications. Meanwhile, European end-of-life directives on electrical and electronic equipment already are having a worldwide effect.
