Heralding a new age of terrific timekeeping, a research group at JILA—a joint institute of the University of Colorado Boulder and the National Institute of Standards and Technology—has unveiled an exp...
Ore-forming fluid trapped in vein quartz as fluid inclusions from tungsten ore at the Takatori mine was extracted by a crush-leach technique. The trace metal content and isotopic composition (δ7Li an...
Helium-rich subdwarf B (He-sdB) stars represent a small group of low-mass hot stars with luminosities greater than those of conventional subdwarf B stars, and effective temperatures lower than those o...
A major obstacle for optical clocks is the frequency shift due to black body radiation. We discuss how one can tackle this problem in an optical lattice clock; in our case 87Sr: firstly, by a measurem...
Acantharian cysts were discovered in sediment trap samples from spring 2007 at 2000 m in the Iceland Basin. Although these single-celled organisms contribute to particulate organic matter flux in the...
An Austrian group has beaten its US counterpart by a matter of days in a race to create a Bose-Einstein condensate (BEC) of strontium atoms.Researchers at the Institute of Quantum Optics and Informati...
Strontium isotopes in precipitation, soil and runoff water can be used to establish a ratio of wet plus dry deposited Sr to Sr released by weathering. This ratio is especially enhanced in areas with...
The strontium isotope composition of seawater has varied over geological time in response to changes in the rates of continental weathering relative to ocean crust alteration. However, the potential o...
In this paper we report for the Hatay Graben, new micropalaeotology, the first strontium dating and new sedimentology. The previous lack of a modern systematic stratigraphy was problematic for the st...
The distribution of Sr contents and isotopes of strontium Sr in the labile fraction of sediments from a channel fillings infill in the Middle Loire alluvial plain is used to highlight aspects of the e...
This study presents strontium isotope and major ion data of shallow groundwater and river water from the Ile du Chambon catchment, located on the Allier river in the Massif Central (France).
The Franck-Condon factors and r-centroids which are very closely related to transition probabilities, have been evaluated by the more reliable nu- merical integration procedure for the band systems ...
Strontium manganate (SrMnO4) in the presence of aluminium chloride (AlCl3) is an efficient reagent for the high yielding oxidative deprotection of aromatic and aliphatic silyl and pyranyl ethers into ...
Strontium isotopic ratios, calcium and strontium contents of calcites in the eolian dust profile during the last 7 Ma at Lingtai were systematically studied. 87Sr/86Sr ratios of calcites change with t...
Cr3+ activated red long persistent phosphorescence through persistence energy transfer from Eu2+ to Cr3+ has been reported in strontium aluminates co-doped with Cr3+, Eu2+ and Dy3+. The decay processe...
