87Sr/86Sr Isotope Ratio as a Tool in Archaeological Investigation: Limits and Risks

open access: yesQuaternary
During the last forty years, the use of strontium isotopes in archaeology and biogeochemical research has spread widely. These isotopes, alone or in combination with others, can contribute to trace past and present environmental conditions.

Galgedil

open access: yesDanish Journal of Archaeology, 2014
Galgedil is a Viking Age cemetery located in the northern part of the Danish island of Funen. Excavations at the site revealed 54 graves containing 59 inhumations and 2 cremation burials. Previous study of the remains to date has included light isotopes

Strontium isotope and element constraints on the paleoenvironment of the latest Ediacaran in the Sichuan Basin, southeastern Tibetan Plateau

open access: yesFrontiers in Earth Science, 2022
The Ediacaran–Cambrian period witnessed episodic extinctions, oxygenation of seawaters, Cambrian explosions, and tectonic events. However, compared with the various high-resolution geochemical records of the early–middle Ediacaran and Cambrian, the ...

Effect of Competing Ions on Multisorption (Cs+, Sr2+) by Composite Sorbents Based on Natural and Synthetic Zeolites

open access: yesEast European Journal of Physics, 2023
In the course of the research, the effect of competing ions (Na+) on multisorption (Cs+, Sr2+) by composite sorbents based on natural and synthetic zeolites under static conditions was studied.

Mass scaling and non-adiabatic effects in photoassociation spectroscopy of ultracold strontium atoms [PDF]

open access: yes, 2014
We report photoassociation spectroscopy of ultracold $^{86}$Sr atoms near the intercombination line and provide theoretical models to describe the obtained bound state energies. We show that using only the molecular states correlating with the $^1S_0$$+$$

Simultaneous isotopic analysis of fission product Sr, Mo, and Ru in spent nuclear fuel particles by resonance ionization mass spectrometry

open access: yesScientific Reports, 2023
Fission product Sr, Mo, and Ru isotopes in six 10-μm particles of spent fuel from a pressurized water reactor were analyzed by resonance ionization mass spectrometry (RIMS) and evaluated for utility in nuclear material characterization.

Degenerate quantum gases of strontium

open access: yes, 2014
Degenerate quantum gases of alkaline-earth-like elements open new opportunities in research areas ranging from molecular physics to the study of strongly correlated systems. These experiments exploit the rich electronic structure of these elements, which

Isotopes in hydrology and hydrogeology [PDF]

open access: yes, 2019
The structure, status, and processes of the groundwater system, which can only be acquired through scientific research efforts, are critical aspects of water resource management. Isotope hydrology and hydrogeology is a genuinely interdisciplinary science.

Volcanism and Volcanic Rocks in Antarctica

open access: yesAntarctic Record, 1977
The distribution of volcanoes in Antarctica, especially those of the later part of Cenozoic time, has considerable bearing on any interpretations of orogenic patterns or history.

The Use of Intrinsic Markers for Studying the Migratory Movements of Bats

open access: yesAnimals, 2021
Mortality of migratory bat species at wind energy facilities is a well-documented phenomenon, and mitigation and management are partially constrained by the current limited knowledge of bat migratory movements.
