    • Wall Slip Heating 

      Gilbert, Peter H.; Giacomin, A. Jeffrey (2015-01-05)
      When molten plastic is extruded, the upper limiting throughput is often dictated by fine irregular distortions of the extrudate surface. Called sharkskin melt fracture, plastics engineers spike plastics formulations with ...
    • Water Sorption Properties of Sub-Micron Thin Ionomer Films 

      Shim, Hyun Ki (2016-02-25)
      This thesis is focused on the water uptake and swelling properties of sub-micron thin ion conducting polymer (ionomer) films. One motivation for this work stems from the need to resolve the discrepancy between high water ...
    • Weld Read-Through Defects in Laser Transmission Welding 

      Cao, Xiaochao (2010-07-02)
      In laser Transmission Welding (LTW), the laser beam passes through the transparent part and is dissipated as heat in the absorbent material through the use of laser-absorbing pigments such as carbon black (CB). This energy ...
    • Zeta Potential of Poly(methyl methacrylate) (PMMA) in Contact with Aqueous Electrolyte–Surfactant Solutions 

      Khademi, Mahmoud; Wang, Wuchun; Reitinger, Wolfgang; Barz, Dominik P. J. (American Chemical Society (ACS), 2017-10-10)
      The addition of surfactants can considerably impact the electrical characteristics of an interface, and the zeta potential measurement is the standard method for its characterization. In this article, a comprehensive study ...
    • πάντα ῥεῖ (Everything Flows): Motto for Rheology 

      Beris, Antony N.; Giacomin, A. Jeffrey (2014-05-23)
