Micron-scale restructuring of gelling silica subjected to shear
de Campo, Liliana; Garvey, Christopher J; Muzny, Chris; Rehm, Christine; Hanley, Howard
Hypothesis/objective We examine the time dependent viscometric behavior of a well-defined system of gelling colloidal silica and how this behavior may be understood from a simple theoretical model which incorporates the microstructure of the gel. The ultra-small angle neutron scattering (USANS) technique is used to interrogate structure during the gelation process. Experiments The investigations focused on a system where both particles and interactions are well-defined: 7 nm silica...[Show more]
