  • Polyphenylene sulfide polymers having improved melt-stability
    Patent number: 10829595
    Abstract: Described here are polyphenylene sulfide (“PPS”) polymers having significantly improved processability. It was surprisingly found that PPS polymers, terminated with specific end-capping agents in specific amounts, had significantly improved melt stability. Because of the significantly improved melt stability, the PPS polymers can be advantageously incorporated into melt processing techniques.
    Type: Grant
    Filed: February 6, 2018
    Date of Patent: November 10, 2020
    Assignee: SOLVAY SPECIALTY POLYMERS USA, LLC
    Inventors: Hong Chen, Peter Mushenheim, Lee Carvell, Erik Nelson, Charles R. Hoppin

  • Microchamber electrochemical cell having a nanoslot
    Patent number: 8969007
    Abstract: A microchamber electrochemical cell and method of using the cell for performing quantitative analysis of various charged macromolecules is presented. The microchamber electrochemical cell includes a substrate, opposing electrodes and at least one nanoslot. The substrate is configured to define a pair of opposing fluid reservoirs. The pair of opposing electrodes are respectively positioned within the opposing fluid reservoirs. Each nanoslot is configured to fluidly connect the opposing fluid reservoirs together. The opposing fluid reservoirs of the microchamber electrochemical cell are fluidly connected to each other only through each nanoslot. Each nanoslot is physically restricted to less than 500 nanometers. One method includes the steps of coupling, filling, measuring, obtaining, performing and preparing.
