Biodegradable Nano-Hybrid Polymer Composite Networks For Regulating Cellular Behavior, Charles Henley Sprague Aug 2015

Biodegradable Nano-Hybrid Polymer Composite Networks For Regulating Cellular Behavior, Charles Henley Sprague

Masters Theses

Photo-crosslinkable polymeric biomaterials have emerged in the field of biomedical research to promote tissue regeneration. For example, scaffolds that can be crosslinked and hardened in situ have been known to make suitable implant alternatives. Since injectable and photo-crosslinkable biomaterials offer the advantage of being minimally invasive, they have emerged to compete with autografts, a current highly invasive method to repair diseased tissue. A series of novel photo-crosslinkable, injectable, and biodegradable nano-hybrid polymers consisting of poly(ε-caprolactone fumarate) (PCLF) and polyhedral oligomeric silsesquioxane (POSS) has been synthesized in our laboratory via polycondensation. To engineer the material properties of the nano-hybrid networks, varied …


Doping Of Fluorchlorozirconate And Borate-Silica Glass Ceramics For Medical Imaging And Fast Neutron Scintillation, Julie Elizabeth Swafford May 2015

Doping Of Fluorchlorozirconate And Borate-Silica Glass Ceramics For Medical Imaging And Fast Neutron Scintillation, Julie Elizabeth Swafford

Masters Theses

Borate silica glass ceramics were produced for neutron scintillation. The Glass ceramics were doped with europium fluoride [EuF2] and cerium chloride [CeCl3]. Isotopic lithium fluoride [6LiF] and boron oxide [10B2O3] were used in most samples while non-isotopic lithium fluoride [LiF] and boron oxide [ B2O3] were used in the rest. When exposed to a neutron beam, samples doped with europium fluoride [EuF2] scintillated while samples doped with cerium chloride [CeCl3] did not. This contradicts current literature on fast scintillation. What …
