Validation and analysis of the geographical origin of Angelica sinensis (Oliv.) Diels using multi-element and stable isotopes [PDF]
PeerJ, 2021 Background Place of origin is an important factor when determining the quality and authenticity of Angelica sinensis for medicinal use. It is important to trace the origin and confirm the regional characteristics of medicinal products for sustainable ...

Collective features of Cr and Fe isotopes [PDF]
Physical Review C, 2014 The question of the sudden increase of collectivity in neutron-rich nuclei when approaching $N=40$ has recently interested both experimentalists and theorists. In this paper we study the development of collectivity along the chromium and iron isotopic chains.

Dating and Tracing the Origin of Enstatite Chondrite Chondrules with Cr Isotopes
Astrophysical Journal, 2020 Chondrules are major components of chondrites and are believed to drive the accretion of planetary embryos. As such, constraining the timing and origin of chondrules is central for understanding the early evolution of the solar system and the formation ...

β -decay properties of neutron-rich Ca, Ti, and Cr isotopes [PDF]
Physical Review C, 2018 Beta-decay properties of neutron-rich Ca, Ti, and Cr isotopes are studied within a deformed proton-neutron quasiparticle random-phase approximation. The underlying mean field is described self-consistently from deformed Skyrme Hartree-Fock calculations ...

Early evolution of the solar accretion disk inferred from Cr-Ti-O isotopes in individual chondrules [PDF]
, 2020 Isotopic anomalies in chondrules hold important clues about the dynamics of mixing and transport processes in the solar accretion disk. The meaning of these anomalies is debated and they have been interpreted to indicate either disk-wide transport of ...

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 ...

High-sensitivity measurement of Cr isotopes by double spike MC-ICP-MS at the 10 ng level.
Analytical Chemistry, 2019 High-sensitivity and high-precision (2SD≤0.06‰) measurement of chromium (Cr) isotopes at the 10ng level was successfully carried out by double spike multiple-collector inductively couple plasma mass spectrometry (MC-ICP-MS).

Search for $\alpha$α + core states in even-even Cr isotopes [PDF]
, 2016 .The $\alpha$α + core structure is investigated in even-even Cr isotopes from the viewpoint of the local potential model. The comparison of $Q_{\alpha}/A$Qα/A values for even-even Cr isotopes and even-even $A = 46, 54, 56, 58$A=46,54,56,58 isobars ...
