Creator:: Oldenkamp, Heidi F.
Abstract:: Xanthan gum, a naturally produced polysaccharide, is biocompatible, and it is commonly used as a food additive. When combined with trivalent ions, such as chromium (III), a gel can form. Various concentrations of xanthan gum and chromium (III) nitrate were combined to evaluate the sol-gel transition of this system. Samples...

Creator:: Gahan, Curran G.
Abstract:: This project discuses the design of a novel apparatus for measuring the interfacial rheological properties of a complex interface while measuring the concentration of redox species within the sub-phase. Preliminary measurements made using the apparatus are also presented. The objective of the preliminary experimentation was to simultaneously measure the interfacial...

Creator:: Mao, Yating
Abstract:: The Brownian motion of micron-scale particles reflects the viscoelastic response of the local environment of the medium. Tracking the thermal fluctuations of these particles is a measure of the rheology of the material at the microscopic scale. This technique is called passive microrheology. Microrheology has been developed to assess the...

Creator:: Tan, Mingyang
Abstract:: Suspensions of particles in fluids are everywhere in our life, such as paints, pharmacies, food, etc. Suspensions can exhibit properties that common fluids do not possess. For example, the paint needs to flow well when brushing so that it can be smeared on the wall, which is aided by the...

Creator:: Turner, Christine
Abstract:: Insoluble surfactants are unique molecules that have the ability to manipulate interfacial properties, becoming useful in numerous applications such as detergents, wetting agents, emulsifiers, foaming agents, dispersants, and more. Interfacial rheology is a field that attempts to characterize the flow properties of insoluble surfactants by exerting a stress on the...

Creator:: Cashen, Ryan K.
Abstract:: Highly elastic solutions have been shown to increase contaminant removal from silicon wafers, indicating the possibility for reduced reliance upon hazardous chemicals and expensive technologies during the fabrication of semiconductor devices. The onset of this enhanced removal is explored using rinsing and siphoning experimentswith polymer fluids of high molecular weights...
