Strontium isotope stratigraphy of the Cretaceous

open access: yesGeological Society, London, Special Publications
Abstract This contribution outlines the methodology of strontium isotope stratigraphy, and reviews the information that underpins the calibration curve of marine- 87 Sr/ 86 Sr against time for the Cretaceous.

Assessing the Utility of Strontium Isotopes in Fossil Dental Calculus

open access: yesJournal of Archaeological Method and Theory
Strontium (Sr) isotopes measured in fossil remains have been a useful tool to assess the geographical origin and even migrations of humans and other animals.

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.

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

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.

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.

A high flux source of cold strontium atoms

open access: yes, 2015
We describe an experimental apparatus capable of achieving a high loading rate of strontium atoms in a magneto-optical trap operating in a high vacuum environment. A key innovation of this setup is a two dimensional magneto-optical trap deflector located

Universal In Situ Isotope Exchange Raman Spectroscopy (IERS) Methodology for Measuring Oxygen Surface Exchange Dynamics Using a Probe Layer

open access: yesAdvanced Functional Materials, EarlyView.
A bespoke multilayer thin film configuration has been designed, which overcomes the material dependency of conventional isotope exchange Raman spectroscopy (IERS). This universal IERS methodology is efficient, non‐destructive and provides additional structural information and time resolution, which can be further extended to various isotopic elements ...

Synergistic Co‐Doping of Barium and Cobalt Enables Stable and Active RuO2 for Acidic Water Oxidation

open access: yesAngewandte Chemie, EarlyView.
Achieving high activity and long‐term durability with non‐iridium catalysts for the acidic oxygen evolution reaction (OER) remains a challenge. This work presents a co‐doping strategy that incorporates Ba and Co into home‐made RuO2, which introduces lattice strain and favorable electronic structure regulation, thereby enhancing both activity and ...
