Characterization Of Fiber Bragg Grating Based, Geometry-Dependent, Magnetostrictive Composite Sensors, Edward Lynch
Characterization Of Fiber Bragg Grating Based, Geometry-Dependent, Magnetostrictive Composite Sensors, Edward Lynch
Theses and Dissertations
Optical sensors based on geometry dependent magnetostrictive composite, having potential applications in current sensing and magnetic field sensing are modeled and evaluated experimentally with an emphasis on their thermal immunity from thermal disturbances. Two sensor geometries composed of a fiber Bragg grating (FBG) embedded in a shaped Terfenol-D/epoxy composite material, which were previously prototyped and tested for magnetic field response, were investigated. When sensing magnetic fields or currents, the primary function of the magnetostrictive composite geometry is to modulate the magnetic flux such that a magnetostrictive strain gradient is induced on the embedded FBG. Simulations and thermal experiments reveal the …

A Comparative Study Of Commercially Available Comfort Fabrics, Melinda Elizabeth Finnie
A Comparative Study Of Commercially Available Comfort Fabrics, Melinda Elizabeth Finnie
Master's Theses and Doctoral Dissertations
The comfort fabric market continues to grow and become more competitive. Consumers expect their active wear to deliver performance beyond simply being a barrier between their body and the environment. Textile manufacturers have taken notice, and there is a wide range of comfort fabrics on the market. This research tests fabric samples from leading comfort fabric technologies: phase change materials, nanotechnology, modified fiber structure and blends, as well as the original comfort fiber, cotton. The most widely recognized comfort fabric properties concern the thermal and moisture management of a fabric. Using a guarded sweating hot plate, standardized test methods, and …
Evaluation Of The Transient Thermal Performance Of A Graphite Foam/Phase Change Material Composite, Michael Paul Trammell
Evaluation Of The Transient Thermal Performance Of A Graphite Foam/Phase Change Material Composite, Michael Paul Trammell
Masters Theses
The thermal transient response of graphite foam infiltrated with paraffin wax as a thermal protection composite was investigated. Graphite foam is a rigid open-celled porous carbon material that exhibits high thermal conductivity along the ligaments. To increase the ability of graphite foam to store heat energy, it was infiltrated with a phase change material, paraffin wax. Filling the foam with a phase change material (PCM) creates a composite that transfers heat through an interconnected network of ligaments to a large surface area of PCM for absorption. Foams were made at various pressures to understand the effect of porosity, which also …
Thermally Annealled Plasmonic Nanostructures, Chaoming Wang
Thermally Annealled Plasmonic Nanostructures, Chaoming Wang
Electronic Theses and Dissertations
Localized surface plasmon resonance (LSPR) is induced in metal nanoparticles by resonance between incident photons and conduction electrons in nanoparticles. For noble metal nanoparticles, LSPR can lead to strong absorbance of ultraviolet-violet light. Although it is well known that LSPR depends on the size and shape of nanoparticles, the inter-particle spacing, the dielectric properties of metal and the surrounding medium, the temperature dependence of LSPR is not well understood. By thermally annealing gold nanoparticle arrays formed by nanosphere lithography, a shift of LSPR peak upon heating has been shown. The thermal characteristics of the plasmonic nanoparticles have been further used …
Age Hardening Of Copper-Aluminum Alloy Castings, Frank Randall
Age Hardening Of Copper-Aluminum Alloy Castings, Frank Randall
Bachelors Theses and Reports, 1928 - 1970
Age hardening occurs in alloys of the solid solution type containing a hardening constituent, be it metal or metallic compound, which is more soluble in the solvent phase at higher temperatures than at lower ones.
