A pilot bioavailable strontium isotope baseline map of Southern British Columbia, Canada
FACETSStrontium isotopes are used for provenience and mobility studies in archaeology, ecology, and forensic studies, and rely on accurate baseline maps that are used to compare and interpret human and animal strontium ratios.

Advances and Outlook of Nickel‐Based MOFs–LDHs Materials for Energy Conversion
Advanced Sustainable Systems, EarlyView.In this graphical abstract, we present the pivotal gap between the activity and stability parameters as far as intergrated Ni‐based MOF/LDF electrocatalysts are concerned. For large scale application, these two parameters should be optimized and furthermore balanced in order to promote sustainable electrocatalytic hydrogen production.

Strontium isotopic anomalies in the Allende Meteorite [PDF]
Geophysical Research Letters, 1978 We report Sr isotope anomalies in two Ca‐Al‐rich inclusions (EK1‐4‐1 and Cl) of the Allende meteorite which also contain anomalies in O, Mg, Ca, Ba, Nd and Sm. The Sr effects correspond to 84Sr or 88Sr deficits of 3.2‰ and 0.8‰ or to 86Sr excesses of 1.6‰ and 0.4‰. Although it cannot be ascertained in which isotope the anomalies reside, arguments based

Spectroscopic determination of the s-wave scattering lengths of 86Sr and 88Sr [PDF]
, 2005 We report the use of photoassociative spectroscopy to determine the ground state s-wave scattering lengths for the main bosonic isotopes of strontium, 86Sr and 88Sr.

Advanced Science, EarlyView.A novel nanolayered manganese oxide material (Na‐NLMO) is prepared using a rapid and straightforward method for efficient adsorption of Sr(II) in both simulated waste liquid and natural water systems. Its excellent adsorption performance of Na‐NLMO could be attributed to the accessible layered structure and negatively charged framework.

Using oxygen isotope analysis and a multi-isotopic approach in determining the region of origin of human remains [PDF]
, 2017 Multi-isotopic approaches have been used effectively to help provide estimated geographic origins for unidentified skeletal remains in cold case homicides and archaeological contexts, when DNA testing was not practical.

Reservoir spectroscopy of 5s5p $^3$P$_2$ - 5s$n$d $^3$D$_{1,2,3}$ transitions in strontium [PDF]
, 2014 We perform spectroscopy on the optical dipole transitions 5s5p $^3$P$_2$ - 5s$n$d $^3$D$_{1,2,3}$, $n \in (5,6)$, for all stable isotopes of atomic strontium.

Aggregate, EarlyView.A new Au18 nanocluster with aggregation‐induced emission (AIE) was synthesized through a strategy of specific‐site “surgery,” which shows a dual‐emission at 645 and 810 nm in the aggregate state. The AIE photophysical behavior and PL mechanism were systematically investigated by experimental and theoretical results.
