    • Affinity chromatography of glucose dehydrogenase 

      Carper, W. Robert; Groutas, William C.; Coffin, D.B. (Springer, 1988-01-15)
      Porcine liver beta-D-glucose dehydrogenase, a multi-functional protein, has been purified to apparent homogeneity. The enzyme has been separated from the endoplasmic reticulum using Triton X-114 and further purified using ...
    • Aggregation models of potential cyclical trimethylsulfonium dicyanamide ionic liquid clusters 

      Carper, W. Robert; Langenwalter, Kevin; Nooruddin, Naveed S.; Kullman, Michael J.; Gerhard, Dirk; Wasserscheid, Peter (American Chemical Society, 2009-02-19)
      Raman and infrared spectra of trimethylsulfonium dicyanamide [(CH(3))(3)SN(CN)(2)] are reported and accurately reproduced by DFT methods (B3LYP and B3PW91), MP2, and MP3, and to a lesser extent by the RHF method. The ...
    • A Bloembergen-Purcell-Pound 13C NMR relaxation study of the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate 

      Carper, W. Robert; Wahlbeck, Phillip G.; Antony, J. H.; Mertens, D.; Dölle, A.; Wasserscheid, Peter (Springer, 2004-03-01)
      The molecular structure and rotational motion of the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]) were studied over a wide temperature range using the Bloembergen-Purcell-Pound 13C NMR ...
    • DFT models of molecular species in carbonate molten salts 

      Carper, W. Robert; Wahlbeck, Phillip G.; Griffiths, Trevor R. (American Chemical Association, 2012-05-10)
      Raman spectra of high temperature carbonate melts are correlated with carbonate species modeled at 923 K using B3LYP/(6-311+G(2d,p)) density functional calculations. Species that are theoretically stable at 923 K include ...
