Redox controls on Cr isotopes in natural waters [PDF]
, 2016 Shifts in Cr isotope fractionations due to microbial activity provide valuable insights into the mechanisms of its cycling, and can be used to quantify biogeochemically mediated redox processes in the environment. In my thesis, microbial Cr isotope fractionations were determined, with a broad range of experimental variables, including species, electron

Investigation of the nuclear structure of the Be, Cr and Cu isotopes
Annals of Nuclear Energy, 2009 The Root-Mean-Square (RMS) nuclear charge, neutron and proton radii, charge, neutron and proton densities, neutron skin thickness and total binding energy per particle were calculated using the Hartree–Fock method with Skyrme forces for the chromium (Cr), copper (Cu) and beryllium (Be) isotopes.

Stabilising the Lattice Oxygen Oxidation Mechanism Through Iridium Single Atoms in Chromium-Doped Cobalt Iron Layered Double Hydroxides. [PDF]
Adv Sci (Weinh)Iridium single atoms and Cr doping synergistically activate and stabilise the lattice oxygen oxidation mechanism in CoFe layered double hydroxides. Electronic modulation enhances metal–oxygen covalency, suppresses over‐oxidation, and enables durable oxygen evolution, delivering high‐performance anion exchange membrane water electrolysis with ...

Cr Stable Isotope Fractionation in Arbuscular Mycorrhizal Dandelion and Cr Uptake by Extraradical Mycelium [PDF]
Pedosphere, 2015 As common soil fungi that form symbioses with most terrestrial plants, arbuscular mycorrhizal (AM) fungi play an important role in plant adaptation to chromium (Cr) contamination. However, little information is available on the underlying mechanisms of AM symbiosis on plant Cr resistance.

Mn‐Cr isotope systematics of the D'Orbigny angrite [PDF]
Meteoritics & Planetary Science, 2004 Abstract— We have conducted a detailed study of the Mn‐Cr systematics of the angrite D'Orbigny. Here, we report Cr isotopic abundances and Mn/Cr ratios in olivine, pyroxene, glass, chromite, and bulk rock samples from D'Orbigny. 53Cr excesses in these samples correlate well with their respective Mn/Cr ratios and define an isochron with a slope that ...

Oxygen isotopes and lakes [PDF]
, 2014 Isotopes are variations of a particular chemical element. It is all to do with the number of neutrons. Oxygen has two main isotopes: 18O which has 10 neutrons and 8 protons; and 16O which has 8 neutrons and 8 protons.

Micro-abrasion–corrosion of a Co–Cr/UHMWPE couple in Ringer's solution : an approach to construction of mechanism and synergism maps for application to bio-implants [PDF]
, 2010 In studies of tribo-corrosion, the degradation of bio-materials has become of increasing research interest in recent years. This is because, in many cases, the interactions of the tribological and corrosion component in biological environments are not ...
