A method of nonaqueous capillary electrophoresis based on ionic liquids was developed with a high electric field (800 V/cm). The ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate was used as modifier to improve the separation efficiency; trishydroxymethylaminomethane and sodium cholate were used as background electrolytes in methanol and acetonitrile. The ionic liquids used in this pap...

Forty two small ruminants, 26 (61.90%) sheep and 16 (38.10%) goats were treated for rumen acidosis. 19 (45.24%), 12 (28.57%), 6 (14.29%) and 5 (11.90%) animals had eaten apple, cooked rice (wazwan left over) turnip and chapatti respectively and manifested clinical form of ruminal acidosis with, 2.86%; (n=18) as mild (Rumen fluid pH=6.32 ±0.09316), 38.09%;(n=16)moderate (Rumen fluid pH=5.71 ±0.0...

BACKGROUND [(18)F]BF4 (-), the first (18)F-labelled PET imaging agent for the sodium/iodide symporter (NIS), was produced by isotopic exchange yielding a product with limited specific activity (SA, ca. 1 GBq/μmol) posing a risk of sub-optimal target-to-background ratios (TBR) in PET images due to saturation of NIS in vivo. We sought to quantify this risk and to develop a method of production of...

High quality bulk single crystals of novel NLO semiorganics : L-arginine tetrafluoroborate (L-AFB) and L-histidine tetrafluoroborate (L-HFB) measuring 78 × 50 × 35 mm have been successfully grown from solution by temperature lowering methods. Solubility curves of these materials have been determined in different solvents, such as water, ethanol and acetone to determine the most suitable solvent...

−Two kinds of ionic liquid, 1-Hexyl-3-methylimidazolium tetrafluoroborate ([Hmim][BF4]) and 1-Methyl-3octylimidazolium tetrafluoroborate ([Omim][BF4]), were used as additives in the linear solvation energy relationships (LSERs) model to investigate the fundamental chemical interactions governing the retention of nine aromatic compounds in acetonitrile/water mobile phases on a C18 column. The ef...
