The use of buffers to maintain the pH within a desired range is a very common practice in
chemical, biochemical and biological studies. Among them, zwitterionic N-substituted …

The fate of chromium (Cr)–a redox sensitive metal–in surface sediments is closely linked to
early diagenetic processes. This review summarizes the main redox pathways that have …

The role of ultramafic rock weathering in global chromium (Cr) budgets and how these may
be linked to changes in Earth's climate over geological time was investigated by compiling …

Due to a growing awareness of the importance of element speciation in a wide range of
analytical applications, 1 the knowledge of the distribution of defined chemical species in …

The widely used β-lactam antibiotics such as penicillins and cephalosporins are known to
be susceptible to CuII-catalyzed hydrolysis at their four-membered β-lactam ring. However …

The solution speciation of a metal has a critical influence on its biological activity in the
environment and is now an important focus of research. In this review, pertinent aspects …

Drinking water treatment typically uses strong oxidants such as chlorine which are capable
of converting CrIII to CrVI. The rates and extent of CrIII oxidation by chlorine are not well …

Citrate released by plants, bacteria, and fungi into soils is subject to abiotic oxidation by
MnO2 (birnessite), yielding 3-ketoglutarate, acetoacetate, and MnII. Citrate loss and …

Accurate discrimination of metal species is a significant analytical challenge. Herein, we
propose a novel methodology based on liquid-phase cyclic chemiluminescence (CCL) for …

Penicillins, a class of widely used β-lactam antibiotics, are known to be susceptible to
catalyzed hydrolysis by metal ions such as CuII. However, new results in this study strongly …
