Copper isotope fractionation during complexation with insolubilized humic acid
, 2010 The bioavailability, mobility, and toxicity of Cu depend on Cu speciation in solution. In natural systems like soils, sediments, lakes, and river waters, organo-Cu complexes are the dominating species.

Experimental study on stable isotopic fractionation of evaporating water under varying temperature
Water Science and Engineering, 2009 The variation of stable isotope ratios in natural waters provides valuable information that can be used to trace water movement. Evaporation plays a crucial role in determining the variation of stable isotopes.

Mass spectrometric measurement of hydrogen isotope fractionation for the reactions of chloromethane with OH and Cl [PDF]
Atmospheric Chemistry and Physics, 2018 Chloromethane (CH3Cl) is an important provider of chlorine to the stratosphere but detailed knowledge of its budget is missing. Stable isotope analysis is a potentially powerful tool to constrain CH3Cl flux estimates.

Equilibrium oxygen- and hydrogen-isotope fractionation between ice and water
, 1991 We have performed high-precision measurements of the isotope-fractionation factors between ice and water. Ice was grown from a stirred water mass on a cooling plate.

Experimental determination of barium isotope fractionation during diffusion and adsorption processes at low temperatures [PDF]
, 2016 Variations in barium (Ba) stable isotope abundances measured in low and high temperature environments have recently received increasing attention. The actual processes controlling Ba isotope fractionation, however, remain mostly elusive.

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
