  • Membrane sensor and method of detecting fouling in a fluid
    Patent number: 10159941
    Abstract: A membrane sensor for detecting fouling, the membrane sensor comprising a first chamber having an inlet and an outlet; a second chamber having an outlet; only one membrane, the membrane being disposed between the first chamber and the second chamber for allowing fluid to permeate the membrane from the first chamber to the second chamber; a first pressure transducer configured for obtaining a first pressure upstream of the membrane; a second pressure transducer configured for obtaining a second pressure downstream of the membrane; and a resistance regulator configured for adjusting the second pressure.

  • Polymeric film surface
    Patent number: 9955687
    Abstract: A surface on a polymeric film having an array of patterned structures, wherein the array of patterned structures influences fluid flow of the surface and causes reduced attachment of a biological material.

  • Determination of pore size in porous materials by evaporative mass loss
    Patent number: 9618441
    Abstract: A method for determination of pore-size distribution in a porous material called evapo porometry (EP) is capable of determining pore sizes from approximately the nanometer scale up to the micron scale. EP determines the pore size based on the evaporative mass loss at constant temperature from porous materials that have been pre-saturated with either a wetting or non-wetting volatile liquid. The saturated porous material is placed in an appropriate test cell on a conventional microbalance to measure liquid mass loss at a constant temperature as a function of time. The mass-loss rate is then related to the pore-size distribution. The microbalance permits measuring the mass as a function of time. The slope of the mass versus time curve is the evaporation rate. The evaporation rate is related to the vapor pressure at the interface between the liquid in the porous material and the ambient gas phase. The vapor pressure in turn is related to the pore diameter.
