A TALE OF TWO CITIES: DIET, HEALTH AND MIGRATION IN POST-MEDIEVAL COVENTRY AND CHELSEA THROUGH BIOGRAPHICAL RECONSTRUCTION, OSTEOARCHAEOLOGY AND ISOTOPE BIOGEOCHEMISTRY [PDF]

open access: yes, 2006
Biogeochemical research has over the past four-and-a-half decades improved our understanding of human interaction with past environments. The application of different isotope systems has allowed archaeologists to interpret ancient diet, migration and ...

A novel hybrid material with calcium and strontium release capability [PDF]

open access: yes, 2012
The preparation of PDMS–TEOS–CaO hybrid materials by sol–gel techniques has been widely described in previous works. Calcium nitrate is the most common source of calcium used in these preparations.

Identification of an Osteochondral Erosion Process in Gout Driven by Fibrinogen‐Integrin Activation and Local MSU Crystallization

open access: yesAdvanced Science, EarlyView.
Cartilage injury promotes local fibrinogen deposition, which accelerates monosodium urate crystallization and activates integrin‐mediated matrix‐degradation. This self‐amplifying cycle drives gout‐related cartilage erosion. Disrupting fibrinogen deposition or restoring the cartilage barrier could interrupt this vicious cycle.

Stabilising the Lattice Oxygen Oxidation Mechanism Through Iridium Single Atoms in Chromium‐Doped Cobalt Iron Layered Double Hydroxides

open access: yesAdvanced Science, EarlyView.
Iridium single atoms and Cr doping synergistically activate and stabilise the lattice oxygen oxidation mechanism in CoFe layered double hydroxides. Electronic modulation enhances metal–oxygen covalency, suppresses over‐oxidation, and enables durable oxygen evolution, delivering high‐performance anion exchange membrane water electrolysis with ...

A pilot bioavailable strontium isotope baseline map of Southern British Columbia, Canada

open access: yesFACETS
Strontium 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.

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.

A normalised seawater strontium isotope curve: possible implications for Neoproterozoic-Cambrian weathering rates and the further oxygenation of the Earth [PDF]

open access: yes, 2007
The strontium isotope composition of seawater is strongly influenced on geological time scales by changes in the rates of continental weathering relative to ocean crust alteration.

Structure and properties of strontium-doped phosphate-based glasses [PDF]

open access: yes, 2008
Owing to similarity in both ionic size and polarity, strontium (Sr2+) is known to behave in a comparable way to calcium (Ca2+), and its role in bone metabolism has been well documented as both anti-resorptive and bone forming.

Minimal Transport Units Govern Oxygen‐Defect Stabilization and Transport for Lightweight Solid Electrolytes

open access: yesAdvanced Science, EarlyView.
Lightweight borate chemistry combined with minimal transport units provides a new pathway for designing lightweight oxide‐ion solid electrolytes. ABSTRACT Solid electrolytes are central to electrochemical energy technologies, including fuel cells, sensors, catalysis, membrane separation, and electrolyser.
