Isotopic Compositions and Elemental Abundances of Chromium in Presolar Silicon Carbide Grains from Asymptotic Giant Branch Stars

The Astrophysical Journal
Isotopes of chromium (Cr) and other iron-group elements are predominantly made in the inner shells of supernovae and are later reprocessed via the slow neutron capture process ( s -process) in asymptotic giant branch (AGB) stars.

Cluster radioactivity of neutron-deficient nuclei in trans-tin region

Scientific Reports, 2020
The possibility of cluster radioactivity (CR) of the neutron-deficient nuclei in the trans-tin region is explored by using the effective liquid drop model (ELDM), generalized liquid drop model (GLDM), and several sets of analytic formulas.

Quantification of the influence of the C, Cr and P contents on the permeability of hydrogen through Fe alloys

Nuclear Materials and Energy, 2022
Ferritic-martensitic steels are candidate materials for blanket structural components of future thermonuclear fusion reactors. However, the tritium inventory that can be retained in different components of the reactor and its ability to migrate through ...

Large-scale shell-model calculations for unnatural-parity high-spin states in neutron-rich Cr and Fe isotopes [PDF]

, 2014
We investigate unnatural-parity high-spin states in neutron-rich Cr and Fe isotopes using large-scale shell-model calculations. These shell-model calculations are carried out within the model space of $fp\text{-shell}+0{g}_{9/2}+1{d}_{5/2}$ orbits with ...

Level lifetimes in 52Cr from DSAM following inelastic neutron scattering: Implications for shape coexistence and E0 strengths [PDF]

EPJ Web of Conferences
Nuclear shape coexistence is a widespread but not yet well understood phenomenon. Electric monopole (E0) transitions are a particularly sensitive probe of shape coexistence.

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.

Exposure risks of trace metal(loid)s on little egrets in a restored polymetallic mining area in eastern China

Global Ecology and Conservation, 2023
Trace metal(loid) pollution from mining activities is a widespread environmental problem, which has stimulated restoration efforts over the world. Tongling is a non-ferrous metal mining area in China with a long history of mining activities.

Fractionation Behavior of Chromium Isotopes during the Sorption of Cr (VI) on Kaolin and its Implications for Using Black Shales as a Paleoredox Archive

Geochemistry Geophysics Geosystems, 2019
Chromium stable isotope variations in marine black shales are increasingly used to constrain redox changes though time. However, how well black shale δ53Cr values represent ambient seawater δ53Cr values is difficult to assess as black shales contain both

Identification of anthropogenic source of Pb and Cd within two tropical seagrass species in South China: Insight from Pb and Cd isotopes

Ecotoxicology and Environmental Safety
Seagrass beds are susceptible to deterioration and heavy metals represent a crucial impact factor. The accumulation of heavy metal in two tropical seagrass species were studied in South China in this study and multiple methods were used to identify the ...

Evaluation of Radioactivity and Heavy Metal Concentrations in Some Liquid Supplements Samples

Ibn Al-Haitham Journal for Pure and Applied Sciences
In recent years, it has become clear that consumers of nutritional supplements, especially adults, tend to consume these supplements for the purpose of improving health and delaying chronic diseases associated with age, in addition to improving physical
