Deuterium-excess as a tracer to determine lake-water contributions along a river

Hydrology Research
Lakes are important landscape elements and sources of streamflow in many catchments. Yet how water storage in lakes and other landscape elements affect streamflow remains poorly understood. We collected weekly water samples from a throughflow lake, along

The relationship of δD and δ18O in soil water and its implications for soil evaporation across distinct rainfall years in winter wheat field in the North China Plain

Agricultural Water Management
Soil evaporation plays a key role in regulating local climate and water loss. Stable isotope ratios of water (²H/¹H and ¹⁸O/¹⁶O) are effective tracers for studying water flux. This study examines three isotope-based indicators deuterium excess (d-excess),

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...

Evaluation of a pantoprazole and 4‐desmethylpantoprazole‐sulfate metabolic ratio as a novel CYP2C19 phenotyping method

British Journal of Clinical Pharmacology, EarlyView.
Aims CYP2C19 is one of the most important pharmacogenes, and its activity is highly variable due to factors such as genetics or drug–drug interactions. Due to the lack of an appropriate endogenous CYP2C19 biomarker, surrogate methods to assess its activity are warranted.

Witchfinding in General and the Censors [PDF]

, 2017
This article examines why it took 33 years before Mark of the Devil (1970) could be distributed in its complete form in the UK. It shows that when the film was first submitted to the British Board of Film Censors in 1970 the cuts required were so ...

The Pivotal Role of Evaporation in Lake Water Isotopic Variability Across Space and Time in a High Arctic Periglacial Landscape

Water Resources Research
Rapidly changing climate is disrupting the High Arctic's water systems. As tracers of hydrological processes, stable water isotopes can be used for high quality monitoring of Arctic waters to better reconstruct past changes and assess future ...
