Diffusing wave spectroscopy applied to material analysis and process control
Diffusing Wave Spectroscopy (DWS) was studied as a method of laboratory analysis of submicron particles, and developed as a prospective in-line, industrial, process control sensor, capable of near real-time feedback. No sample pre-treatment was required and measurement was via a noninvasive, …

Dynamic light scattering and diffusing wave spectroscopy studies of the microscopic dynamics of polystyrene latex spheres suspened in glycerol
… scattering in the single scattering limit and diffusing wave spectroscopy in the multiple scattering regime using a charge coupled device [CCD] camera as our detector. Our experiments, which investigated suspensions of various concentrations [0.001</=0</=0.075], extended over length scales …

Understanding Structure-Property Relationships for Impact Polystyrene
… to improve product quality and process control. Diffusing wave spectroscopy measurements and analysis coupled with microfluidic capillary viscometry was verified as a quantitatively accurate tool using polystyrene standards and prepared solutions of well-characterized impact polystyrene samples. …

Multiple Light Scattering from Isotropic and Anosotropic Turbid Media
… a result of new experimental probes, such as Diffusing-Wave Spectroscopy (DWS) [7, 9, 10, 11], that enable us to measure particle displacements down to 1Å or even smaller, and thereby offer the possibility to quantitatively test hydrodynamic theories [4, 6] of nondiffusive particle motion, …

Non-equilibrium polymeric complex fluids
… micelle (WLM) system, in conjunction with Diffusing Wave Spectroscopy (DWS) and traditional bulk rheology. It is shown for the first time that equimolar (eM) SDS:CAPB WLM samples can be considered ‘model’ systems, and form close approximations of Maxwellian systems on the addition of extra …

Near-Field Hydrodynamics of Optically Trapped Colloids in Simple and Complex Fluids
… block copolymer system: Pluronic F127. Using Diffusing Wave Spectroscopy (DWS), we construct a detailed phase diagram based on temperature- and concentration-dependent microrheology. The viscoelasticity behaviour is quantitatively analysed using complex G modulus, where we observe F127’s …

DNA scaffolds for functional hydrogels
… field of rheology and micro-rheology, with the diffusing wave spectroscopy (DWS) technique illustrated explicitly as an example passive micro-rheology tool. Afterwards, a critical literature review on computational modelling of DNA systems is present, followed by the thesis outline at the end. …
