  • Termite resistance of MDF panels treated with various Boron Compounds
    International Journal of Molecular Sciences, 2009
    Co-Authors: Mustafa Usta, Derya Ustaomer, S. Nami Kartal, Sedat Ondaral
    Abstract:

    In this study, the effects of various Boron Compounds on the termite resistance of MDF panels were evaluated. Either borax (BX), boric acid (BA), zinc borate (ZB), or sodium perborate tetrahydrate (SPT) were added to urea-formaldehyde (UF) resin at target contents of 1%, 1.5%, 2% and 2.5% based on dry fiber weight. The panels were then manufactured using 12% urea-formaldehyde resin and 1% NH(4)Cl. MDF samples from the panels were tested against the subterranean termites, Coptotermes formosanus Shiraki. Laboratory termite resistance tests showed that all samples containing Boron Compounds had greater resistance against termite attack compared to untreated MDF samples. At the second and third weeks of exposure, nearly 100% termite mortalities were recorded in all Boron compound treated samples. The highest termite mortalities were determined in the samples with either BA or BX. Also, it was found that SPT showed notable performance on the termite mortality. As chemical loadings increased, termite mortalities increased, and at the same time the weight losses of the samples decreased.

  • lewis acidity of Boron Compounds
    Coordination Chemistry Reviews, 2014
    Co-Authors: Igor B Sivaev, V I Bregadze
    Abstract:

    Abstract The effects of different electronic and structural factors in determining the Lewis acidity of Boron Compounds are analyzed. Scales of Lewis acidity for Boron Lewis acids based on the Gutmann–Beckett and Childs methods have been constructed using data available in the literature. The Lewis acidities of transient Boron Lewis acids have been estimated and their high Lewis acidity has been confirmed.

  • polyhedral Boron Compounds as potential diagnostic and therapeutic antitumor agents
    Anti-cancer Agents in Medicinal Chemistry, 2006
    Co-Authors: V I Bregadze, Igor B Sivaev, Sergey A Glazun
    Abstract:

    The use of polyhedral Boron hydrides for cancer treatment is traditionally connected with Boron neutron capture therapy. More recently, polyhedral borate anions were proposed as carriers of radionuclide label for targeted radionuclide therapy and diagnostics of cancer. Some metal derivatives of carboranes were found to demonstrate significant antitumor activity themselves. This review is designed to highlight the recent work concerning various fields of potential application of polyhedral Boron Compounds in anticancer diagnostics and therapy.
