We demonstrate time-resolved terahertz transmission ellipsometry of vertically aligned multi-walled carbon nanotubes. The angle-resolved transmission measurements reveal anisotropic characteristics of the terahertz electrodynamics in multi-walled carbon nanotubes. The anisotropy is, however, unexpectedly weak: the ratio of the tube-axis conductivity to the transverse conductivity, sigma[subscript z]/sigma[subscript xy] [similar or equal to]...
The particulate optical backscattering coefficient (bbₚ) is a
fundamental optical property that allows monitoring of marine suspended
particles both in situ and from space. Backscattering measurements in the
open ocean are still scarce, however, especially in oligotrophic regions.
Consequently, uncertainties remain in bbₚ parameterizations as well as
in satellite estimates...
The defect mechanisms that underpin the high energy density dielectric 0.8BaTiO₃–0.2Bi(Zn₁/₂Ti₁/₂) O₃ were investigated. Characterization of the nominally stoichiometric composition revealed the presence of a Ti³⁺-related defect center, which is correlated with lower resistivities and an electrically heterogeneous microstructure. In compositions with 2 mol. % Ba-deficiency, a barium vacancy-oxygen vacancy...
My thesis is comprised of two articles, titled "Interpreting Britomart's Encounters with Art: The Cyclic Nature of Ekphrasis in Spenser's Faerie Queene III," and "Picture This, Imagine That: Teaching Visual Literacy in the Disciplines." The purpose of my first article is to argue that Edmund Spenser uses ekphrasis in his...
