Evaluation and design of polymer systems for enhanced microwave heating
… after the onset of percolation. A novel solidstate processing technique for thermoset systems was also evaluated. By milling the reactants to a fine powder, and mixing them completely, the extent to which diffusion limited the process was significantly reduced: increased milling resulted …

C2- and C3-Symmetric Meta-substituted Thienyl Benzenes: A Comparative Synthetic and Structural Study
… of cross-linking (C2 vs. C3), are compared. The solidstate structures of C2- and C3-symmetric (n = 1) compounds are also discussed. Furthermore, the syntheses of novel meta-substituted benzenes that bear both thiophene and halogen groups are reported (C, n = 0 or 1). Further elaboration of the …

Synthetic and structural studies of Calix[4]pyrogallolarenes: towards biological applications
… have been synthesised and their solidstate and in-solution behaviour has been studied by diffusion NMR spectroscopy and single crystal X-ray diffraction. It has been found that calix nano-capsules can be formed by calix[4]pyrogallolarenes in polar protic solvents when the alkyl …

An Investigation of the Magnetic and Electrical Properties of YNi3
… such as ZrZn2, Ni3Al and YNi3 are of interest to solidstate research because they demonstrate non-Fermi-Liquid behaviour and allow us to probe the quantum nature of the solid state in magnetic materials. Spin fluctuation theory is currentlythe most successful tool we have for trying to describe …

Efficient multiscale methods for micro/nanoscale solid state heat transfer
… approximation for describing small-scale solidstate heat transfer. We first discuss a Monte Carlo (MC) solution method that builds upon the deviational energy-based Monte Carlo method presented in [J.-P. Péraud and N.G. Hadjiconstantinou, Physical Review B, 84(20), p. 205331, 2011]. By …

NMR investigations of cyanate resins
… been investigated both in solution and in the solidstate by NMR spectroscopy. To facilitate the study, 13C and 15N isotopic labelled cyanate resins were used. The main curing reaction was found to be the formation of triazine rings and no NMR evidence for the formation of dimeric or other …

Surface plasmons for enhanced metal-semiconductor-metal photodetectors
… in integrated optics, photovoltaics, solidstate lighting and imaging below the diffraction limit. In Chapter 10 we conclude this thesis by summarizing and discussing some possible applications and future research directions based on SPP field concentration.

From high power terahertz quantum cascade lasers to terahertz light amplifiers
… intersubband transitions, provides the first solidstate fundamental oscillator at the frequency range from 1.2 to 5.1 THz. Due to the subwavelength confinement nature of the metal-metal waveguide used in most of the THz QC lasers, far-field beam patterns from lasers with simple Fabry-Perot …

Supported Cobalt Oxide Catalysts for the Preferential Oxidation of Carbon Monoxide: An in situ Investigation
… Strong interactions can also promote the solidstate reaction between the species from the nanoparticle with those from the support, leading to the formation of metal-support compounds (MSCs). The supports SiO2, TiO2 and Al2O3 are well known for this phenomenon, and consequently, allow for …

Development and Characterization of Friction Bit Joining: A New Solid State Spot Joining Technology Applied to Dissimilar Al/Steel Joints
<p>Friction bit joining (FBJ) is a new solid-state spot joining technology developed in cooperation between Brigham Young University of Provo Utah, and MegaStir Technologies of West Bountiful Utah. Although capable of joining several different material combinations, this research focuses on the …
