Research Projects:
Our Light Scattering Spectroscopy Lab is currently involved in 6 projects. All of them make use of at least one of the two optical techniques: Dynamics Light Scattering (DLS) and Static Light Scattering (SLS) Spectroscopy. 1. Polymeric microgel nanoparticles: Synthesis, structure, dynamics, critical behavior, loading capability, and sensitivity to environmental conditions. Assessment of possible applications: e.g. smart coatings and paints, permeability modifiers, biosensors, targeted drug delivery agents. 2. Transport and viscoelastic properties of polymer chains in dilute and concentrated aqueous solutions. Critical behavior of polymer solutions. 3. Translational and rotational diffusion of biological proteins in water and glycerol solutions (in collaboration with Polymer Science, UAkron and Physics, U Tennessee). 4. Structure and translational/rotational dynamics of thermally responsive supramolecular hydrogels & protein-based nanoparticles (in collaboration with Bioengineering, CSU and Macromolecular Science, CWRU) 5. Aggregation of micelles in surfactant solutions. Exploring their structure and dynamics under different solvent conditions. 6. Zeolite nanocrystals and boron nitride nanoparticles in clear solutions. Monitoring interactions of nanocrystals and surfactant molecules. (in collaboration with UDelft, Holland and Semenov Institute of Chemical Physics, Russia) All research projects are run with the help from undergraduate or/and graduate students. Opportunities for funded student involvement exist (Especially for the summer).
