A Rubric For Electrochemical Testing Of Metallic Biomaterials, Frederick G. De La Fuente
A Rubric For Electrochemical Testing Of Metallic Biomaterials, Frederick G. De La Fuente
Master's Theses
Corrosion is a major factor for the failure of metallic medical implants. Testing a metal’s suseptability to corrosion prior to implantation is key to a successful implantation. Electrochemical processes were used in this study to evaluate the characteristics of corrosion of both AISI 316 stainless steel and titanium alloy Ti6Al4V, welded and non-welded. Linear, potentiodynamic, and cyclic polarization curves were produced by the PARC 2273 potentiostat showing the corrosion tendencies of the metals in four unique solutions 3.5% NaCl, 0.35% NaCl, phosphate buffered saline solution (PBS), and Butterfield phosphate buffered solution (BPS). The concentration of chloride ions in solutions affected …
Functional Co-Substituted Poly[(Amino Acid Ester)Phosphazene] Biomaterials, Amanda L. Baillargeon
Functional Co-Substituted Poly[(Amino Acid Ester)Phosphazene] Biomaterials, Amanda L. Baillargeon
Electronic Thesis and Dissertation Repository
The development of new and improved biomaterials is essential for tissue engineering and regenerative medicine applications. Amino acid-based polyphosphazenes are being explored as scaffold materials for tissue engineering applications due to their non-toxic degradation products and tunable material properties. This work focuses on the synthesis of non-functional and novel functional poly[(amino acid ester)phosphazene]s using a facile method of thermal ring opening polymerization followed by one-pot room temperature substitution. The family of polyphosphazenes developed in this work is based on L-alanine (PNEAs), L-phenylalanine (PNEFs), and L-methionine (PNEMs) with L-glutamic acid imparting the functionality. Characterization of these materials demonstrated that the one-pot …

USF Tampa Graduate Theses and Dissertations
Silicon carbide (SiC) has been used for centuries as an industrial abrasive and has been
actively researched since the 1960's as a robust material for power electronic applications.
Despite being the first semiconductor to emit blue light in 1907, it has only recently been
discovered that the material has crucial properties ideal for long-term, implantable biomedical
devices. This is due to the fact that the material offers superior biocompatibility and
hemocompatibility while providing rigid mechanical and chemical stability. In addition, the material
is a wide-bandgap semiconductor that can be used for optoelectronics, light delivery, and optical
sensors, which is the …
