Many patients who need dental treatment like dental crowns and dentures become more and more these days. The materials used to make these products are important for further use. Three main materials used in nowadays dental treatments for patients are studied in this article, which are metal materials, ceramic materials, and plastic materials. The a...

The goal of this project was to determine the processing parameters for forming a porous ceramic filter that can function as a longer-lasting alternative to polymer filters used in bioprocessing applications. The ceramic filter targeted the capability to filter out particles 0.5 μm and larger that are suspended in a fluid in a dead-end filtration c...

Piezoelectric actuators frequently exhibit a time-dependent behavioral phenomenon known as hysteresis, resulting in a lag in the deformation of the actuator compared to linear models. The presence of hysteresis complicates control systems involving piezoelectric actuators. However, traditional modeling methods for piezoelectric actuated smart struc...

Ceramics membranes are made in a wide variety of different techniques using a wide variety of different materials. However, many of the common techniques utilize a slurry of ceramic particles, additives, and either organic solvent or water that is shaped into a membrane, left to dry, and then sintered together. Drying is a time consuming process, o...

Pulsed laser ablation has a wide array of applications in the materials science processing of today. This thesis focuses on the use of pulsed laser ablation to i) process ceramic materials to introduce hydrophobic properties to their surfaces for use in lunar dust adhesion mitigation and ii) synthesize Ag nanoparticles for use in antibacterial appl...

This thesis involves the fabrication and characterization of devices made from two different superconducting materials: yttrium barium copper oxide (YBCO), a high-TC complex oxide, and niobium nitride (NbN), a low-TC transition metal nitride. Both types of devices are fabricated on strontium titanate substrates, which provides a good lattice match ...

Direct current (DC) and radio frequency (RF) sputtering methods have been commonplace in industry for several decades and widely studied in literature. Hard films of nitrides, such as titanium nitride (TiN), have been deposited using reactive DC sputtering onto cutting tools and medical devices extensively as well. For these applications, the films...

Positive Thermal Coefficients, PTCs, are materials that abruptly change in resistance in response to changes in temperature. The purpose of this experiment is to explore the viability of using the switching type ceramic PTC thermistor as a replacement for current resistive heaters. These types of PTCs have a nonlinear change in resistance with incr...

Femtosecond laser surface processing (FLSP) is applied to a range of materials in this thesis. The materials studied were a carbon fiber reinforced polymer (CFRP), a thermosetting polymer, silicon nitride (Si3N4), and ceramic alumina. The CFRP is a composite material consisting of a thermosetting polymer and carbon fibers. The CFRP are referred to ...

Polymer concrete is a composite material used to replace cast iron and steel in wafer grinding machines for vibration damping. During the grinding and lapping processes of manufacturing silicon wafers, excessive vibrations may cause subsurface damage which requires additional polishing and reduces yield. Nine compositions containing various levels ...
