  1. Control of Thermal Expansion, Behavior on Compression, and Guest Loading in Framework Materials

    15 Sep 2021 | Contributor(s):: Baxter, Samuel J.

    Advisors: Angus Wilkinson, Younan Xia, John Zhang, Christopher Jones, Henry La PierreEach chapter in this thesis focuses on open framework systems found to display anomalous properties relating to their unique structures. The systems investigated were chosen for their open framework form,...

  2. Negative Thermal Expansion, Behavior on Compression, and Other Anomalous Properties in Rhenium Trioxide Structured Mixed Metal Fluorides

    20 May 2020 | Contributor(s):: Hester, Brett R.

    Advisors: Angus P. Wilkinson, Joseph Sadighi, David Sholl, Younan Xia, Z. John ZhangIn order to gain fundamental insight into the control of thermal expansion, this dissertation examines the thermal expansion and response to pressure of several mixed metal fluorides (M2+M4+F6), using...

  3. The Role of Disorder in Determining the Physical Properties of Negative Thermal Expansion Materials

    17 Aug 2017 | Contributor(s):: Gallington, Leighanne C.

    Advisors: Angus P. Wilkinson, Joseph W. Perry, Mostafa A. El-Sayed, Z. John Zhang, Naresh N. ThadhaniIn this dissertation, the role of disorder in determining the physical properties of materials in the AM2O8 and AM2O7 families was investigated. A link was established between orientational...
