The complete metabolic fate of propranolol has been difficult to assess because of its complexity.
The aim of this study was therefore to develop an analytical approach that would permit …

A large portion of the dose of propranolol in animals and man is unaccounted for. Using
radiotracer and HPLC techniques, five previously unrecognized polar and labile metabolites …

Abstract Treatment of o‐nitrobenzenesulfonyl chloride (3) with 5‐aminotetrazole (5‐AT) gave
[(2‐nitrophenyl)‐sulfonyl]carbamimidic azide (6), a ring‐opened isomer of the expected N‐(…

An automated high-performance liquid chromatographic (HPLC) column-switching system is
described for the analysis of medroxalol, a potential antihypertensive agent, in plasma. The …

Climate change is warming tundra ecosystems in the Arctic, resulting in the decomposition
of previously-frozen soil organic matter (SOM) and release of carbon (C) to the atmosphere; …

In situ X-ray absorption spectroscopy (XAS) at the Pt L3 edge is a useful probe for Pt–O
interactions at polymer electrolyte membrane fuel cell (PEMFC) cathodes. We show that XAS …

… 8 shows a plot of log [thin space (1/6-em)] K versus z/IR for DFOB and rhizoferrin, yielding
estimated log [thin space (1/6-em)] K + Cr(III)HDFOB = 30.6 and log [thin space (1/6-em)] K Cr(…

… Vapor vents are quite common on the travertine terraces; however, acid-altered areas
occur at only a few locations (Bargar and Muffler, I975) where the hot vapors contain enough …

The U 4f line is commonly used to determine uranium oxidation states with X-ray photoelectron
spectroscopy (XPS). In contrast, the XPS of the shallow core-levels of uranium are rarely …

Sediment interfaces in alluvial aquifers have a disproportionately large influence on
biogeochemical activity and, therefore, on groundwater quality. Previous work showed that exports …
