Dendron Avidity Platforms with Orthogonal Focal Point Coupling Site.
(2010)
This thesis explores the design and synthesis of bifunctional or modular platforms from poly(amidoamine) (PAMAM) dendrons. PAMAM dendrons with an orthogonal focal point are evaluated, testing several click chemistry ...
Universal Scaling of Linear and Nonlinear Rheological Properties of Semidilute and Concentrated Polymer Solutions.
(2008)
This dissertation examines the universal rheological behavior of linear polymers in solution. The universality of the dependence of zero-shear viscosity on concentration for both flexible and semiflexible polymers in good ...
Carbide and Nitride Based Catalysts for Synthesis Gas Conversion.
(2011)
The production of fuels and chemicals from syngas (H2 and CO) plays a critical role in our economy and will play an even greater role in the future as we transition from petroleum-derived products to biomass-derived products. ...
Microdroplet-Enabled Co-Cultivation and Characterization of Microbial Communities.
(2012)
The majority of existing microbial species, in particular bacteria living in synergistic
communities, have not been cultured in the laboratory. One important reason
behind this unculturability" is that conventional laboratory ...
Fabrication of Spheroidal Microparticles from Biodegradable Polymers for Drug Delivery Application.
(2012)
This work describes the novel fabrication of biodegradable prolate spheroids from poly(lactic-co-glycolic acid) (PLGA) polymers via oil-in-water (O/W) and water-in-oil-in-water (W/O/W) emulsion solvent evaporation methods. ...
Utilizing Inverted Colloidal Crystal Scaffolds to Engineer In Vitro Bone and Bone Marrow.
(2010)
Numerous studies have shown that cells and tissues grown in 2D substrates behave dramatically differently than in the body, and that culturing them in three dimensional (3D) scaffolds can restore some of this lost ...
Combined theoretical and experimental study of the linear rheology of model and commercial polymers
(2011)
Polymer rheology is a very sensitive indicator of polymer long chain branching, and therefore can be used as a tool to determine polymer structures. This dissertation is thus focused on the study of the relationship between ...
Composite Silver/Titania Photocatalysts for Visible Light Water Splitting: The Role of Silver Surface Plasmons.
(2011)
Photocatalytic conversion of water to hydrogen and oxygen is a promising avenue for the production of fuels from solar energy. While many semiconductors can absorb solar photons and catalyze the production of hydrogen and ...
Role of Carrier Size, Hemodynamics and Hemorheology in the Efficacy of Vascular-Targeted Spherical Drug Carriers.
(2012)
Spherical polymeric particles in the submicron down to tens nanometers size range are extensively proposed for use as vascular-targeted drug carriers (VTDCs); however, very limited studies have explored their capacity to ...
Synthesis and Characterization of Titania Nanotubes for Photocatalytic Water-Splitting and Carbon Dioxide Methanation.
(2011)
As carbon dioxide emissions from coal-based electricity generation increase, new technologies are required to convert carbon dioxide to useable fuels, such as methane and hydrogen. The Sabatier reaction would be a useful ...
