Diplomacy Rhetoric and the Human Rights Appeals of Jeane J. Kirkpatrick and Vernon A. Walters

Description: This thesis investigates the extent to which Ambassador Kirkpatrick's and Ambassador Walters' United Nations discourses on human rights reflects the rhetorical themes of "prophetic dualism" and "technocratic realism." A metaphoric analysis of six speeches reveals that both Kirkpatrick's and Walters' arguments were framed through an ideological division between Democracy and Communism. The presence of "prophetic dualism" in Kirkpatrick's and Walters' discourses is explained as an extension of Pr… more

Direct Atomic Level Controlled Growth and Characterization of h-BN and Graphene Heterostructures on Magnetic Substrates for Spintronic Applications

Description: Epitaxial multilayer h-BN(0001) heterostructures and graphene/h-BN heterostructures have many potential applications in spintronics. The use of h-BN and graphene require atomically precise control and azimuthal alignment of the individual layers in the structure. These in turn require fabrication of devices by direct scalable methods rather than physical transfer of BN and graphene flakes, and such scalable methods are also critical for industrially compatible development of 2D devices.
