    • The Flexure-based Microgap Rheometer (FMR) 

      Clasen, Christian; Gearing, Brian P.; McKinley, Gareth H. (2007-01-23)
      We describe the design and construction of a new microrheometer designed to facilitate the viscometric study of complex fluids with very small sample volumes (1-10 μl)and gaps of micrometer dimensions. The Flexure-based ...
    • How Dilute are Dilute Solutions in Extensional Flows? 

      Clasen, Christian; Plog, J.P.; Kulicke, W.-M.; Owens, M.; Macosko, C.; e.a. (2007-01-23)
      We investigate the concentration-dependence of the characteristic relaxation time of dilute polymer solutions in transient uniaxial elongational flow. A series of monodisperse polystyrene solutions of five different ...
    • Linear to Non-linear Rheology of Wheat Flour Dough 

      Ng, Trevor S.K.; McKinley, Gareth H.; Padmanabhan, Mahesh (2007-01-23)
      We provide an overview of transient extensional rheometry techniques for wheat flour doughs in which the deformation and material response is well defined. The behavior of a range of model doughs was explored with a ...
