  1. Compounds of Pentacoordinate (10-Boron-5) and Hexacoordinate (12-Boron-6) Hypervalent Boron

    Lee, David YenUniversity of Illinois at Urbana-Champaign2014

    Efficient synthetic routes to 2-substituted pyridines and 2,6-disubstituted pyridine 1-oxides are described, involving direct ortho lithiation with the sterically hindered base, lithium 2,2,6,6-tetramethylpiperidide, in the presence of electrophiles that are compatible with the base, e.g., …

  2. Processability of Nickel-Boron Nanolayer Coated Boron Carbide

    Zhu, XiaojingVirginia Tech2008

    This dissertation work focuses on the processability improvement of B4C, especially the compaction and sintering improvement of B4C by applying a Ni-B nanolayer coating on individual B4C particles. A modified electroless coating procedure was proposed and employed to coat nanometer Ni-B layer onto …

  7. Electronic Stucture of Elemental Boron

    Wang, LiaoyuanUniversity of Missouri--Kansas City2010

    Boron has complex structures in its crystalline forms that lead to a variety of properties. The primary phases of elemental boron are α-B12, t-B50, γ-B28, and β-B106 and are the focus of this thesis. As a preliminary step to elucidate the properties of these phases, ab initio calculations have …
