  • High-temperature, high-pressure NMR probe for superconducting magnets

    Creator:
    Mullen, Corina P.
    Abstract:
    A high-temperature, high-pressure autoclave has been adapted for use with a high-field nuclear magnetic resonance spectrometer. The autoclave has an internal pressure range of atmospheric pressure to 1.5 kbar and a temperature range of 273 K to 1900 K. The autoclave is usable in a high field (8 T) magnet...

  • Study of the Effects of Chain Whip Length and Bar Length on the Characteristics of Chain Shot

    Creator:
    Shannon, Eric R.
    Abstract:
    Timber harvesters are high powered industrial grade rigs used to fell, delimb, and cut to size large trees. Hydraulic motors power sprockets that drive chains around a guide bar that get extended through logs during cuts. As technological advances allow for higher speeds a phenomenon called “chain shot” has...

  • A microscopic study of the interaction between aliovalent dopants and native defects in group IV oxides : indium and cadmium in ceria and zirconia

    Creator:
    Zacate, Matthew O.
    Abstract:
    In order to understand better the defect structure and dynamics associated with lower valent dopants complexed with native defects in group IV oxides, In/Cd perturbed angular correlation spectroscopy was performed in ceria and zirconia. Examining the orientation symmetry axis of defects in ceria single crystals at low temperature has allowed...

  • Level structure of ¹⁵²Gd populated in ¹⁵²Tb β decay

    Creator:
    Stapels, Christopher John
    Abstract:
    As part of a research program to study the transitional region of N=88 isotones, ¹⁵²Tb was produced by the reaction ¹⁵¹Eu(α,3n)¹⁵²Tb in the 88" cyclotron located at LBNL. Gamma-ray spectroscopy of the radiation emitted from excited ¹⁵²Gd following the β⁺ decay of ¹⁵²Tb has been performed using an array of...

  • Amorphous TiO₂ : A Thin Film Synthesis Route to Stabilization of Metastable TiO₂ Brookite

    Creator:
    Haggerty, James E. S.
    Abstract:
    Structure-specific synthesis processes are of key importance to the growth of polymorphic functional compounds such as TiO₂, where material properties strongly depend on structure as well as chemistry. The robust growth of the brookite polymorph of TiO₂, a promising photocatalyst, has been difficult in both powder and thin-film forms due...

  • Nonlinear terahertz spectroscopy of carbon nanomaterials and semiconductor nanostructures

    Creator:
    Paul, Michael Jason
    Abstract:
    This thesis will cover my work relating to the developing field of terahertz (THz) science and technology. It will present experimental and theoretical studies investigating the optical and electrical properties of various material systems using novel THz imaging and spectroscopy techniques. Due to its low photon energy, THz imaging and...

  • Model of student understanding of probability in modern physics

    Creator:
    Wattanakasiwich, Pornrat
    Abstract:
    This study aimed to investigate students' models of probability in a modern physics context. The study was divided into three phases. The first phase explored student pre-knowledge about probability before modem physics instruction. The second phase investigated student understanding of concepts related to probability such as wave-particle behavior, the uncertainty...

  • Optical, electronic, and thermodynamic properties of layered mixed anion compounds

    Creator:
    Vielma, Jason Michael
    Abstract:
    Mixed anion compounds that form ZrCuSiAs-type crystal structures exhibit remarkable properties such as superconductivity at low temperatures, hole conduction with optical transparency in the visible region, and exciton absorption at room temperature. In this thesis, properties of a selected group of materials out of the very large set of mixed...

  • Exchange interaction studies in magnetic semiconductors by neutron scattering

    Creator:
    Wiren, Zachary Quincy
    Abstract:
    Theories predict that making a dilute magnetic semiconductor strongly p -type would allow it to remain ferromagnetic at room temperature. This is of intrest as a ferromagnetic semiconductor would allow for a great many applications in the field of spintronics. Neutron scattering experiments were undertaken to better understand the antiferromagnetic...

  • Creating Community: A Case Study of Students’ Experiences in Inquiry-Based Learning

    Creator:
    Schaub, Branwen
    Abstract:
    We now have broad consensus in the mathematics education research community that active, inquiry-based classrooms provide a wealth of learning benefits for students (Freeman et al., 2014; Laursen et al., 2014; Theobald et al., 2020). Classrooms that utilize inquiry throughout the entire structure of the course, as opposed to the...
