Fabrication of Biological Pigment Nanowires by Inkjet Printing

Creator:: Cao, Yu
Abstract:: Digital inkjet printing is developing quickly today because inkjet printing processes consume less energy and water and produce less waste discharge than traditional dyeing and other printing technologies. Inkjet printing provides more versatility and flexibility in terms of printing patterns and colors. Natural pigments are gaining more attention today as...

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...

Application of polyallylamine as a dry strength agent

Creator:: Rathi, Mahesh Shrikant
Abstract:: Dry strength is an inherent structural property of a paper sheet. It is due primarily to the development of fiber-to-fiber bonds. Polyamines, especially polyallylamine·HC1 (PAA), were found to be suitable mordants for rosin sizing. However, their effectiveness as dry strength agents has not been studied. In this study polyallylamine·HC1 was...

Shear Moduli Estimates of Thermoplastic Natural Fiber Composites via Off-Axis Tensile Tests

Creator:: Johnson, Natalie N.
Abstract:: Fiber reinforced polymers have gained considerable attention due to their wide range of applications, leading to significative concerns for end-of-life recyclability and disposal. Natural fibers and recycled carbon fibers, coupled with thermoplastic matrices can provide a sustainable and environmentally friendly alternative to traditional materials. This study focused on experimental materials...

Concentration Effects on Enhanced Particle Removal with Viscoelastic Fluids

Creator:: Cashen, Ryan K.
Abstract:: Highly elastic solutions have been shown to increase contaminant removal from silicon wafers, indicating the possibility for reduced reliance upon hazardous chemicals and expensive technologies during the fabrication of semiconductor devices. The onset of this enhanced removal is explored using rinsing and siphoning experimentswith polymer fluids of high molecular weights...

A study of the dynamics and rheology of passive and active suspensions of particles with various geometries

Creator:: Tan, Mingyang
Abstract:: Suspensions of particles in fluids are everywhere in our life, such as paints, pharmacies, food, etc. Suspensions can exhibit properties that common fluids do not possess. For example, the paint needs to flow well when brushing so that it can be smeared on the wall, which is aided by the...

Sensitivity and Partitioning in Remote Sensing Based Evapotranspiration Models

Creator:: Talsma, Carl J.
Abstract:: Satellite Based evapotranspiration (ET) models have become a dominant means to estimate large-scale surface fluxes of water. Global and regional ET estimates are important parameters in many climate forecasts and hydrologic models. However, large scale partitioning of ET into soil evaporation, transpiration, and canopy interceptions remains largely unknown and modeled...

Natural Variability of Nitrogen and Phosphorus in a Forested Headwater Stream System in the Oregon Coast Range

Creator:: Steadman, Casey L.
Abstract:: Our understanding of nitrogen (N) and phosphorus (P) variability in forested stream systems with minimal disturbance is confounded by the complex interactions of hydrologic and biogeochemical controls. In this thesis, our studies evaluate the variability of stream water N and P in a forested, headwater system in the Oregon Coast...

A 3-D Tomographic Model of the P-wave Velocity Structure of the Central Cascadia Forearc

Creator:: Kenyon, Christopher Bradford
Abstract:: Signals from the R/V Langseth’s tuned airgun array were recorded on an array of 33 EarthScope FlexArray seismometers deployed in the Oregon Coast Range from 43.5° to 45°N as part of the 2012 Ridge2Trench experiment to image the structure of the Juan de Fuca plate. This segment of the Juan...

The adsorption of human recombinant factor VIII in the presence of the nonionic triblock surfactant Pluronic® F-68 at the air-water interface

Creator:: Alkhatib, Aveen K.
Abstract:: The adsorption behavior of a human recombinant Factor VIII (rFVIII) in the presence of the nonionic, poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock surfactant Pluronic® F-68 was evaluated by dynamic air-water tensiometry. Surface tension kinetics were recorded for F-68 in the absence of protein at concentrations ranging from 0 to 10,000...
