  • Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

    Creator:
    Chibwe, Leah
    Abstract:
    Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...

  • Human exposure to polycyclic aromatic hydrocarbons : global cancer risk and metabolism

    Creator:
    Motorykin, Oleksii
    Abstract:
    In recent decades, there has been increased attention on human exposure to, and subsequently toxicity of, Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are widespread organic pollutants and some have been shown to be toxic, carcinogenic and mutagenic. This research was focused on understanding the link between global PAH emissions and lung...

  • The optical properties of multi-scale plasmonic structures and their applications in optical characterization and imaging

    Creator:
    Kuhta, Nicholas Anthony
    Abstract:
    The optical response of metallic structures is dominated by the dynamics of their free electron plasma. Plasmonics, the area of optics specializing in the electromagnetic behavior of heterogeneous structures with metallic inclusions, is undergoing rapid development, fueled in part by recent progress in experimental fabrication techniques and novel theoretical approaches....

  • Computational nanooptics in hyperbolic metamaterials and plasmonic structures

    Creator:
    Thongrattanasiri, Sukosin
    Abstract:
    This dissertation concerns several problems in the fields of light interaction with nanostructured media, metamaterials, and plasmonics. We present a technique capable of extending operational bandwidth of hyperbolic metamaterials based on interleaved highly-doped InGaAs and undoped AlInAs multilayer stacks. The experimental results confirm theoretical predictions, exhibiting broadband negative refraction response...

  • Subwavelength light confinement and quantum chaos in micro- and nano-structured metamaterials

    Creator:
    Govyadinov, Alexander A.
    Abstract:
    This dissertation concerns a broad range of unique phenomena related to the light propagation at nano- and micro-scales. To access the nano-domain, we introduce anisotropy-based waveguides with positive- and negative-index modes. These novel structures allow energy propagation in subwavelength regions and, in contrast to surface waves, have the mode structure...
