Comparative analysis of metabolic and functional cardiac alterations in diet‐ and genetically induced mouse models of cardiac dysfunction

open access: yesThe FEBS Journal, EarlyView.
Dietary and genetic stress trigger different routes to heart failure. In mice, a carbohydrate‐free high‐fat diet caused mitochondrial dysfunction and impaired energy production with preserved pumping function, while genetic obesity led to heart enlargement, fibrosis, and reduced function.

Seawater strontium isotopes at the Cretaceous-Tertiary boundary [PDF]

open access: yes
Anomalously high values of Seawater Sr-87/Sr-86 near the Cretaceous-Tertiary (K-T) boundary have been reported. However, few of the data from the literature are from a single continuous section, and perhaps the most complete study of the boundary region,

STRONTIUM ISOTOPE SYSTEMATICS AND GEOCHEMISTRY OF COAL UTILIZATION BY-PRODUCTS [PDF]

open access: yes, 2007
Coal combustion for energy generation creates large quantities of solid coal utilization by-products (CUB), including fly ash, bottom ash, and flue gas desulfurization products. These materials are either used in environmental and industrial applications

RioM‐1: A New Calcite Reference Material for U‐Pb LA‐ICP‐MS Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points RioM‐1 calcite was characterised for trace elements, U‐Pb geochronology, Sr and O isotopes using ID‐TIMS, LA‐ICP‐MS and SIMS. U‐Pb dates from ID‐TIMS and LA‐ICP‐MS across several independent laboratories returned identical results within uncertainty.

Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

Peixe Zircon as a Quality Control Reference Material in U‐Pb Geochronology by LA‐ICP‐MS

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Peixe#0 zircon was characterised for U‐Pb geochronology using CA‐ID‐TIMS, SIMS and a long‐term LA‐ICP‐MS data set. The consistent results establish Peixe#0 as a reference material for U‐Pb quality control. Trace element heterogeneity requires careful, CL‐guided spot selection.

Strontium isotope stratigraphy: LOWESS version 3: best fit to the marine Sr-isotope curve for 0-509 Ma and accompanying look-up table for deriving numerical age [PDF]

open access: yes, 2001
An improved and updated version of the statistical LOWESS fit to the marine 87Sr/86Sr record and a revised look-up table (V3:10/99; available from j.mcarthur@ucl.ac.uk) based upon it enables straightforward conversion of 87Sr/86Sr to numerical age, and ...
