    UCST behavior in blend systems of isotactic polystyrene/poly(4-methyl styrene) in comparison with atactic polystyrene/poly(4-methyl styrene)

    Blends of poly(4-methylstyrene) (P4MS) with polystyrene (iPS) exhibit an upper critical solution temperature (UCST) at ca. 270 °C. The overall phase behavior and trend of variation in the phase diagrams for th...

    On-line state estimation of biomass based on acid production in Zymomonas mobilis cultures

    The concentrations of biomass, substrate and product are very important state variables of almost every bioprocess and generally unable to be measured directly in␣situ due to the lack of reliable sensors. In ...
