| 요약 | Characterizing the rheological properties of polymeric and colloidal gels during dynamic phase transitions is critical in developing targeted products for industrial and home care use. These materials require specific rheology that allow them to |
| 요약 | We begin by characterizing the gelation of poly(ethylene glycol) (PEG) hydrogels at varying polymeric interactions and gelation mechanisms. The gels consist of a 20,000 g mol--1 4 arm star PEG backbone end-functionalized with either acrylate or |
| 요약 | Microrheology is then used to measure the degradation and gelation of a fibrous colloidal gel, hydrogenated castor oil. HCO undergoes a heterogeneous phase transition based on an osmotic pressure gradient, making MPT an ideal measurement tool. T |
| 요약 | To increase the amount of information gained from MPT experiments, we develop a technique to simultaneously track a bi-disperse population of probe particles. 0.5 and 2.0 microm particles are tracked separately using a brightness based radius of |
| 요약 | To determine if colloidal rearrangement during phase transition is effecting the scaffold structure of HCO, a micro2rheology, microfluidics with microrheology, is developed. A two-layer microfluidic device is designed to exchange fluid surroundi |
| 요약 | The effect of shear imparted on the sample during preparation is determined using a combination of microrheology, micro2rheology, and bulk rheology. (Abstract shortened by ProQuest.). |
