Ab Initio Phase Diagram of Chromium to 2.5 TPa
Applied Sciences, 2022 Chromium possesses remarkable physical properties such as hardness and corrosion resistance. Chromium is also a very important geophysical material as it is assumed that lighter Cr isotopes were dissolved in the Earth’s molten core during the planet’s ...

Yankuang ceshi, 2019 BACKGROUND With the development of Multi-collector Thermal Ionization Mass Spectrometry (MC-TIMS) and Multi-collector Inductively Coupled Plasma-Mass Spectrometry (MC-ICP-MS), Cr isotopes had been successfully measured at a high resolution.

Chromium Isotope Systematics in Modern and Ancient Microbialites [PDF]
Minerals, 2020 Changes in stable chromium isotopes (denoted as δ53Cr) in ancient carbonate sediments are increasingly used to reconstruct the oxygenation history in Earth’s atmosphere and oceans through time. As a significant proportion of marine carbonate older than the Cambrian is microbially-mediated, the utility of δ53Cr values in ancient carbonates hinges on ...

Frontiers in Immunology, 2023 Reliable and sensitive characterization assays are important determinants of the successful clinical translation of immunotherapies. For the assessment of cytolytic potential, the chromium 51 (51Cr) release assay has long been considered the gold ...

Principles and Treatment Methods for Metal Isotopes Analysis
Yankuang ceshi, 2021 BACKGROUND In the past twenty years, methods for metal isotopes analysis (iron, copper, zinc, magnesium, calcium, lithium, molybdenum, selenium, mercury, chromium, cadmium, alum, barium, titanium, etc.) have been established.

E3S Web of Conferences, 2013 Hexavalent chromium-contaminated groundwaters and sediments in northern Italy have been studied using the Cr stable-isotope systematics and electron spin resonance spectroscopy (ESR), in order to explore redox changes and soil-groundwater interactions ...

Chromium isotopes in marine hydrothermal sediments [PDF]
Chemical Geology, 2019 Hydrothermal chromium (Cr) cycling contributes to marine Cr inventories and their Cr isotopic composition, yet Cr isotope effects associated with this cycling remain poorly documented. Here we determine the distribution, isotopic composition, and diagenetic mobility of Cr in hydrothermal sediments from the distal flank of the South East Pacific Rise ...

Nature Communications, 2017 Identifying the original impactor from craters remains challenging. Here, the authors use chromium and oxygen isotopes to indicate that the Zhamanshin astrobleme impactor was a carbonaceous chrondrite by demonstrating that depleted 17O values are due to ...
