3.24 Engineering and Entrepreneurship: Building from the Ground Up Confirming the presence of microplastics in seafood currently requires breaking the sample down through chemical digestion, a slow and destructive process poorly suited for routine screening. Drexel's Lifeng Zhou, working with colleagues at Virginia Tech, has developed a faster alternative that can detect microplastics directly on fish surfaces without any sample preparation.

3.19 Drexel Engineers Design Screw-Driven Flow Cell to Power Next-Generation Energy Storage Drawing on an ancient pumping concept, Drexel engineers have developed a flow cell that handles thick carbon suspensions conventional designs can't manage — a potential breakthrough for grid-scale energy storage. The design also shows promise for water treatment, direct lithium extraction and other industrial applications where high-viscosity fluids need to stay electrochemically active.
