Evaluation of the Strontium Isotope Ratios in Soil–Plant–Fruit: A Comprehensive Study on Vignola Cherry (Ciliegia di Vignola PGI) [PDF]

open access: yesFoods
This study investigates the potential of strontium isotopes as a geographical tracer for Vignola cherries. Despite several studies having employed this indicator to trace the origin of food products, the mechanisms underlying the fractionation and ...

Is What Comes out the Same as What Goes in? A Preliminary Investigation of the Isotopic Impacts of Digestion by Red‐Tailed Hawks (Buteo jamaicensis) and Eurasian Eagle Owls (Bubo bubo) [PDF]

open access: yesEcology and Evolution
We investigated isotopic diet‐excreta offset (Δdiet‐excreta) for predatory birds, and the isotopic influence of bird digestion on consumed prey tissues.

Understanding intra-individual isotopic variability in modern cremated human remains for forensic and archaeological studies. [PDF]

open access: yesPLoS ONE
Cremated bone fragments can be studied using structural, elemental, and isotope analyses in archaeological contexts to reconstruct funerary practices and understand past mobility and migrations of populations that practiced cremation.

Cooling and trapping of ultracold strontium isotopic mixtures [PDF]

open access: greenPhysical Review A, 2005
We present the simultaneous cooling and trapping of an isotopic mixture in a magneto-optical trap and we describe the transfer of the mixture into a conservative, far-off resonant dipole trap. The mixture is prepared with a new technique that applies to intermediate and heavy alkaline earth like atoms.

Determination of the deactivating properties of shampoos for cesium, strontium and cobalt [PDF]

open access: yesЯдерна фізика та енергетика, 2023
The decontamination properties of shampoos for cesium, strontium, and cobalt were determined. The method has been developed for determining the decontaminating properties of shampoos. The chemical part of the study includes the preparation of hair, which

Strontium isotope effect on Solid-Liquid extraction system using a polymer resin with 2.2.2-Cryptand anchor groups [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2020
The chemical isotope exchange with macrocyclic polyethers is one of the relatively new methods for isotope separation. These separations are based on the phenomenon of isotope effect, in which the kinetic and the stability of the complex formation ...

Using the geographic detector model to identify factors controlling the bioavailability of Sr isotopes in China

open access: yesFrontiers in Earth Science, 2023
Strontium isotope ratios (87Sr/86Sr) are a widely applied tool in provenance applications in archaeology, paleoecology, forensics, and food science. Bedrock Sr is naturally and anthropogenically transferred to other reservoirs on the Earth’s surface ...
