Impactor identification with spallogenic Cr isotopes: The Wabar impact craters (Saudi Arabia) [PDF]

Precise measurements of Cr isotopic composition of terrestrial impactites have successfully provided evidence for the presence of extraterrestrial material and have, in some cases, allowed the identification of the type of impactor responsible for the ...

Petrogenesis and Geodynamic Implications of Late Triassic Mogetong Adakitic Pluton in East Kunlun Orogen, Northern Tibet: Constraints from Zircon U–Pb–Hf Isotopes and Whole-Rock Geochemistry

Frontiers in Earth Science, 2022
Adakites or adakitic rocks usually show special geochemical signatures and are petrological probes to reveal the tectono–magmatic evolutionary history of paleo–orogenic belts. Here, we present a comprehensive study on the zircon U–Pb geochronology, whole-

Monitoring Cr toxicity and remediation processes - combining a whole-cell bioreporter and Cr isotope techniques [PDF]

Water Research, 2019
Bioremediation is a sustainable and cost-effective means of contaminant detoxification. Although Cr(VI) is toxic at high concentrations, various microbes can utilise it as an electron accepter in the bioremediation process, and reduce it to the less toxic form Cr(III).

Enhanced collectivity along the N=Z line: Lifetime measurements in 44Ti, 48Cr, and 52Fe

Physics Letters B, 2017
Lifetimes of the 21+ states in 44Ti, 48,50Cr, and 52Fe were determined with high accuracy exploiting the recoil distance Doppler-shift method. The reduced E2 transition strengths of 44Ti and 52Fe differ considerably from previously known values.

Efficacy of Trophic Transfer of Radioactive and Stable Isotopes of Metals to Zoobenthos-Feeding Fish of the Yenisei River [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2013
Accumulation of radioactive and stable isotopes of metals in trophic chain of the Yenisei River leading to zoobenthivorous fish species, dace (Leuciscus leuciscus baicalensis) and grayling (Thymallus arcticus), have been investigated.

An Improved Cr-EA-IRMS Method for the Effective Determination of the Hydrogen Isotopes in Coal Samples

Frontiers in Chemistry, 2022
Hydrogen isotope analysis of coal is an important tool in the geochemical analysis of coal. The traditional method of hydrogen isotope analysis of coal requires the oxidation of organic matter bound hydrogen in coal to water by an oxidizing agent and ...

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes

Advanced Materials, EarlyView.
This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for
