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 ...
First-principles Modeling of the Surface Reactivity of Transition Metals with Perturbed Electronic Properties
(2011)
The surface reactivity of transition metals can be varied substantially by introducing perturbations into the electronic system. Previously, the electronic properties of transition metal surfaces have been tailored for ...
Theoretical and Experimental Investigation of Switch-Like Responses Arising from Multisite Protein Phosphorylation.
(2011)
Switch-like responses are important regulatory features of biological processes involving
binary decisions such as cell division. Multisite protein phosphorylation is a proposed
mechanism for achieving switch-like behaviors. ...
Mesoscale modeling and computational simulation studies of the self-assembly of heterogeneous colloidal systems.
(2010)
Over the last two decades researchers have advanced the field of colloidal synthesis
by developing new synthesis techniques. Colloidal particles are known to self-assemble
into various unique architectures. However, there ...
Evaluating the Effect of a Strong Metal-Support Interaction on the Activity of Molybdenum Carbide Supported Platinum Water-Gas Shift Catalysts.
(2010)
The goal of this research was to understand an apparent strong interaction between platinum and molybdenum carbide (Mo2C), and its effect on the water-gas shift (WGS) activity of Pt/Mo2C catalysts. The state of the art ...
