Influence of Laser Repetition Rate, Fluence and Spot Size on LA‐Q‐ICP‐MS/MS 87Sr/86Sr Precision: Insights from Apatites and Silicate Glasses

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Higher laser repetition rate, fluence and larger spot size increase signal intensity. Higher laser repetition rate produces overlaps in aerosolised particles, improving signal stability and precision. For Sr‐rich materials, moderate spot diameter (≤ 60 μm), 3 J cm‐2 fluence and ≥ 12 Hz repetition rate are recommended.

Impact of River Morphology on River–Groundwater Exchange in Braided River Systems

open access: yesGroundwater, EarlyView.
Abstract Braided river systems are an important source for groundwater recharge, but their complex morphology makes river–groundwater exchange fluxes difficult to estimate. Their river channel morphology changes frequently after floods, which has effects on recharge rates that have rarely been studied in the past.

PERIODIZING GEOLOGICALLY OUTWITH (AND WITHOUT?) THE ANTHROPOCENE: PASTS, AGENCIES, AND THE TERRESTRIAL

open access: yesHistory and Theory, EarlyView.
ABSTRACT As a periodization that is generally understood to refer to an era of Terrestrial relationships that developed with modernization and nuclearization, the Anthropocene cannot be applied simply to premodern histories and texts. However, it has introduced historians to geological periodization as a mode of describing periods of changed ...

Theological Doctrines as Scientific Theories? Thinking along with and beyond McGrath

open access: yesInternational Journal of Systematic Theology, EarlyView.
Abstract McGrath's recent analysis of the parallels between scientific theory formation and the development of theological doctrine in The Nature of Christian Doctrine (OUP, 2024) is insightful and largely compelling, but also raises some questions and areas for further exploration. First, there is a remarkable back‐and‐forth between uses of ‘doctrine’

When biology meets materials science – Interdisciplinary applications of electron microscopy

open access: yesJournal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.
