A Study of the Design Possibilities and Techniques of Pounding Plants into Fabric and Paper

Description: The problem of investigating the possibilities of direct design transfer from plant to fabric and paper was divided into two parts. The first part is concerned with the exploration of the mechanics of the transfer. Invloved in this process are the technique of manipulating tools, of selecting suitable fabrics and paper, of determining chemicals that would facilitate the printing process and of experimenting with ways to preserve the finished design. The evaluation of the usability and durabilit… more

Catalytic Properties and Mechanical Behavior of Metallic Glass Powders

Description: Lack of crystalline order and microstructural features such as grain/grain-boundary in metallic glasses results in a suite of remarkable attributes including very high strength, close to theoretical elasticity, high corrosion and wear resistance, and soft magnetic properties. By altering the morphology and tuning of composition, MGs may be transformed into high-performance catalytic materials. In this study, the catalytic properties of metallic glass powders were demonstrated in dissociating to… more

Evaluation of normalization methods for cDNA microarray data by k-NN classification

Description: Non-biological factors give rise to unwanted variations in cDNA microarray data. There are many normalization methods designed to remove such variations. However, to date there have been few published systematic evaluations of these techniques for removing variations arising from dye biases in the context of downstream, higher-order analytical tasks such as classification. Ten location normalization methods that adjust spatial- and/or intensity-dependent dye biases, and three scale methods that… more

Dynamical Study of Guest-Host Orientational Interaction in LiquidCrystalline Materials

Description: Guest-host interaction has long been a subject of interest in many disciplines. Emphasis is often on how a small amount of guest substance could significantly affect the properties of a host material. This thesis describe our work in studying a guest-host effect where dye-doping of liquid crystalline materials greatly enhances the optical Kerr nonlinearity of the material. The dye molecules, upon excitation and via intermolecular interaction, provides an extra torque to reorient the host molecu… more

Nonlinear Optical Absorption and Refraction Study of Metallophthalocyanine Dyes

Description: This dissertation deals with the characterization of the nonlinear absorption and refraction of two representative metallophthalocyanine dyes: chloro aluminum phthalocyanine dissolved in methanol, referred to as CAP, and a silicon naphthalocyanine derivative dissolved in toluene, referred to as SiNc. Using the Z-scan technique, the experiments are performed on both the picosecond and nanosecond timescales at a wavelength of 0.532 ÎĽm.

Whole Genome Amplification of DNA from Residual Cells Left By Incidental Contact

Description: Typically, the number of genetic analyses performed on a sample of DNA has been limited by the amount of starting material. For example, the small quantity of DNA obtained from the cells within a fingerprint meant that only a five to ten reactions could be performed off a single sample. We demonstrate a process wherein total genomic DNA is amplified before forensic typing analysis. The process requires as few as 8 cells and produces sufficient material for up to 20,000 subsequent PCR reactions.… more

Time-Dependent Interfacial Properties and DNAPL Mobility

Description: Interfacial properties play a major role in governing where and how dense nonaqueous phase liquids (DNAPLs) move in the subsurface. Interfacial tension and contact angle measurements were obtained for a simple, single component DNAPL (tetrachloroethene, PCE), complex laboratory DNAPLs (PCE plus Sudan IV dye), and a field DNAPL from the Savannah River Site (SRS) M-Area DNAPL (PCE, trichloroethene [TCE], and maching oils). Interfacial properties for complex DNAPLs were time-dependent, a phenomeno… more

Modeling preferential water flow and solute transport in unsaturated soil using the active region model

Description: Preferential flow and solute transport are common processes in the unsaturated soil, in which distributions of soil water content and solute concentrations are often characterized as fractal patterns. An active region model (ARM) was recently proposed to describe the preferential flow and transport patterns. In this study, ARM governing equations were derived to model the preferential soil water flow and solute transport processes. To evaluate the ARM equations, dye infiltration experiments wer… more

DISSOLVED OXYGEN--INDIGO-CARMINE METHOD

Description: The indigo-carmine method is a simple, rapid, accurate colorimetric procedure for determining small amounts of dissolved oxygen in water (0 to 50 ppm). A solution of reduced indigo-carmine dye added to a water sample is oxidized by the presence of any dissolved oxygen and changes color. The change in color of the dye is directly proportional to the amount of dissolved oxygen present in the sample and can be determined by using a Johnson color comparator. (W.L.H.)

Lignocellulose-Based Nanobiocomposites for Water Purification

Description: The research focuses on the synthesis and application of multifunctional lignocellulosic biomass bioadsorbent and nanobiocomposites for water purification. A bioadsorbent was prepared from kenaf fiber by self-activation without the use of any toxic chemicals in an innovative method. Silver nanoparticles were synthesized by the green route and then impregnated on the surface of kenaf-based activated carbon (KAC), and hemp fibers by heating and photoirradiation. The formation of hemp-based and ke… more
