Synthesis and characterization of the liquid ionic solvent 1-butyl-3-methylimidazolium tetrafluoroborate
A room temperature liquid ionic compound, 1-butyl-3-methylimidazolium tetrafluoroborate, has been synthesized and characterized in terms of viscosity and density. The kinematic viscosity, the density, and the absolute ...
Chemical extractions to determine metal partitioning to sediments and soils
Previously, we have reported on methods for sequential extractions to determine the partitioning of contaminants and stable elements within soils and sediments. Recently, we have explored single step extractions to obtain ...
A sterospecific colorimetric assay for (s,s)-Adenosylmethionine quantification based on thiopurine methyltransferase-catalyzed thiol methylation
S-Adenosyl-L-methionine (AdoMet or SAM) that is biologically synthesized by AdoMet synthetase bears an s-configuration at the sulfur atom. The chiral sulfonium spontaneously racemizes to form a mixture of s-and R-isomers ...
