Evidence of hydrological control of Sr behavior in stream water (Strengbach catchment, Vosges mountains, France) [PDF]

open access: yes, 2002
Strontium and particularly 87Sr/86Sr ratios in stream water have often been used to calculate weathering rates in catchments. Nevertheless, in the literature, discharge variation effects on the geochemical behavior of Sr are often omitted or considered ...

Machine-learning-based automated loading of strontium isotopes into magneto-optical trap

open access: yesAIP Advances, 2023
We implemented optimization techniques of machine learning (ML) to obtain the mutually exclusive sets of experimental parameters that maximize the number of strontium atoms of different isotopes (88Sr, 86Sr, and 87Sr) in a magneto-optical trap (MOT ...

Sr-isotope analysis of speleothems by LA-MC-ICP-MS: High temporal resolution and fast data acquisition [PDF]

open access: yes, 2017
Speleothems are well established climate archives. A wide array of geochemical proxies, including stable isotopes and trace elements are present within speleothems to reconstruct past climate variability.

The influence of water–rock interactions on household well water in an area of high prevalence chronic kidney disease of unknown aetiology (CKDu)

open access: yesnpj Clean Water, 2021
Poor drinking water quality in household wells is hypothesised as being a potential contributor to the high prevalence of chronic kidney disease of uncertain aetiology (CKDu) among the farming communities of the Medawachchiya area, Anuradhapura, Sri ...

Seaweed against strontium and preussian blue against cesium

open access: yesRangifer, 1988
The fact that alginates bind strontium and cyanates bind cesium and are capable of removing these elements from living organisms is scientifically verified. Zeolites offer another possibility for exchange of these ions.

Silver Linings at the Dawn of a “Golden Age”

open access: yesFrontiers in Ecology and Evolution, 2021
Nearly four decades after the first applications of strontium isotope analyses in archaeology and paleoecology research, it could be said that we are entering a “Golden Age”.

Scale of human mobility in the southern Andes (Argentina and Chile): A new framework based on strontium isotopes.

open access: yesAmerican Journal of Physical Anthropology, 2017
OBJECTIVES The goal of this article is to assess the scale of human paleomobility and ecological complementarity between the lowlands and highlands in the southern Andes during the last 2,300 years.

Strontium isotope (87Sr/86Sr) data from archaeological sites in Utah, USA

open access: yesData in Brief, 2019
The information presented here includes the results of strontium isotope analysis on 75 baseline samples from nine Fremont sites in Utah. The baseline samples are of lagomorphs and rodents with limited foraging ranges.

Isotope shifts of natural Sr+ measured by laser fluorescence in a sympathetically cooled Coulomb crystal [PDF]

open access: yes, 2014
We measured by laser spectroscopy the isotope shifts between naturally-occurring even-isotopes of strontium ions for both the $5s\,\,^2S_{1/2}\to 5p\,\,^2P_{1/2}$ (violet) and the $4d\,\,^2D_{3/2}\to 5p\,\,^2P_{1/2}$ (infrared) dipole-allowed optical ...
