Order in side-chain liquid crystalline diblock copolymers
… small angle X-ray scattering (SAXS) and electron microscopy, and thermal transitions were identified using polarized microscopy, calorimetry, and elevated temperature-SAXS. We found the formation of micron-sized domains and focal-conic superstructures to depend on the length of the PS block and …

A Novel Shear Thinning and Thixotropic Plga Micro Particulate Suspension System for Controlled Drug Delivery
… scanning calorimetry (DSC), scanning electron microscopy (SEM) and polarized microscopy studies. Drug release mechanism was studied by conducting plasticizer release studies and mathematical modeling.</p> <p> Results indicated transformation of drug release from an erosion based process to a …

Syneresis and Rheology Mechanisms of a Latex-HEUR Associative Thickener System
… cone. The mixtures were also studied by microscopy and dynamic oscillatory testing. The chemical structures of the Cal Poly HEURs were determined by proton nuclear magnetic resonance spectroscopy (<sup>1</sup>H NMR) and the molecular weight by gel permeation chromatography (GPC).</p> …

Holographic Investigation of Azobenzene-Containing Low-Molecular-Weight Compounds
… the long axis of the chromophores. If linearly polarized light is incident on the sample, these isomerizations result in a reorientation of this axis perpendicular to the light polarization. A holographic light grating, which can be formed by the interference of two coherent laser beams, leads …

Interferometric Scattering Microscopy: Theory, Simulation, and Experiment
… through the lens of a specialized optical microscopy technique known as interferometric scattering (iSCAT), first demonstrated in the early 2000s. To establish the theoretical limits of nanoscale optical tracking, I derive theories of iSCAT imaging yielding fully quantitative predictions in …
