Preparation and characterization of polymer-SiO₂ hybrids

Creator:: Ferguson, Morgan L.
Abstract:: In a search for designed materials that mimic those found in biological systems, combining polymers with inorganic materials in sol-gel chemistry processes has gained momentum in the research world since the 1990's. This work methodically investigated the properties of several related polymer-SiO₂ hybrids prepared by a simple methodology that could...

Identifying Audiences: A Rhetorical Analysis of Mary Shaw’s Suffrage Plays

Creator:: Wright, Amanda R.
Abstract:: American women’s quest for equality came into focus in the early 1900s. Amidst the cultural and societal forces pushing for suffrage, some chose the mechanism of theater. This thesis is a work of rhetorical criticism. It applies Lloyd Bitzer’s situational approach to two suffrage theater artifacts: Mary Shaw's The Woman...

Bioactive glass filled resin composites : mechanical properties and resistance to secondary tooth decay

Creator:: Khvostenko, Dmytro
Abstract:: Dental resin composites are widely used in modern dentistry due to their aesthetic appearance. However, resin based restorations have inferior mechanical properties (fracture is the second reason for restorations replacement) in comparison to alloy based composites and their antimicrobial properties still remain poor, leading to secondary tooth decay development on...

New development of beta-chitosan from jumbo squid pens (Dosidicus gigas) and its structural, physicochemical, and biological properties, New development of β-chitosan from jumbo squid pens (Dosidicus gigas) and its structural, physicochemical, and biological properties

Creator:: Jung, Jooyeoun
Abstract:: β-chitin/chitosan extracted from newly utilized jumbo squid (Dosidicus gigas) pens were investigated in respect to their physicochemical properties, polymeric structures, deacetylation and depolymerization characteristics, and antioxidant and antibacterial activities. These functional properties were further compared with α-chitin/chitosan prepared from shrimp shells. Due to the low mineral content (< 1%) and...

Material Properties in Ceramic Injection Molding Design

Creator:: Kate, Kunal H.
Abstract:: Ceramic injection molding (CIM) is a high volume, near net shaping process used to manufacture ceramic parts with complex features and shapes. In CIM design it is important to understand the molding behavior as a function of powder-polymer (feedstock) composition in order to achieve desired part dimensions and properties, at...

Models for predicting powder-polymer properties and their use in injection molding simulations of aluminum nitride

Creator:: Kate, Kunal H.
Abstract:: Powder injection molding (PIM) is widely used to manufacture complex-shaped ceramic and metal components in high production volumes. In order to design and fabricate PIM components, it is important to know a number of material properties at different powder- polymer compositions. In this thesis, several predictive models for estimating rheological,...

The effects of nanoparticle addition on the processing, structure and properties of SiC and AlN

Creator:: Onbattuvelli, Valmikanathan P.
Abstract:: Silicon carbide (SiC) and aluminum nitride (AlN) exhibit a combination of thermal and mechanical properties that are relevant to applications in electronics, aerospace, defense and automotive industries. However, the successful translation of these properties into final applications lies in the net-shaping of these ceramics into fully dense microstructures. Increasing the...

Development of mullite-zirconia composite feedstocks for powder injection molding

Creator:: Martin, Renee A.
Abstract:: Mullite-zirconia composites have been slated for use in a novel miniature ceramic turbine engine components developed for unmanned air vehicle (UAV) engine applications. Economically feasible production of these complex components requires the use of a near-net shape process such as powder injection molding (PIM). This thesis explores the development and...
