Effect of hofmeister salts on the compressibility of bovine serum albumin

Perven, Sultana 23 April 2013 (has links)
Determination of whether ion specific potassium halides binding with BSA occurred within the experimental conditions was the aim of the study. Ultrasound velocity measurements using a Resoscan system and density measurements using a DMA 5000M density meter were made to analyse BSA conformation in the presence of potassium salts of the Hofmeister series. It was found that the density and the adiabatic compressibility of BSA-potassium halide mixed aqueous solutions cannot be predicted from the density and the adiabatic compressibility of potassium halide solutions and that of BSA solutions. Interaction occurs between BSA and Br-, I- and F- ions in mixed aqueous solutions of BSA-KBr, BSA-KI and BSA-KF, but there is no interaction between BSA and Cl- ion in BSA-KCl mixed aqueous solution. The interaction of ion to BSA is ion non-specific to the Hofmeister series.

Cationic and Dicationic Phosphine Complexes of Tin and Germanium

MacDonald, Elizabeth 09 August 2013 (has links)
This dissertation explores the synthesis and characterization of phosphine stabilized tetrel (group 14) cations. Tetrel cations are readily generated by reacting a halogermane or halostannane with a Lewis acid to generate an in situ germylium, stannylium cation or an in situ germyldiylium, stannyldiylium dication. A Lewis base such as a phosphine is added to the mixture to produce the corresponding salt with dative P-Sn or P-Ge connectivity. Tin and germanium salts represent new as well as unique cationic structures for phosphorus containing species. The preparation of these salts is proven to be generalizable, reproducible, and can be isolated as pure materials in moderate to high yields.
