Assessing Structural Geological Controls on Groundwater Processes in Mountain Settings: Insights From Three‐Dimensional Numerical Modeling

Water Resources Research, Volume 61, Issue 8, August 2025.
Abstract Mountains play a critical role in the hydrological cycle by transferring heavy precipitation to lowland aquifers. However, their complexity and remoteness limit our understanding of groundwater flow, particularly the influence of faults. To fill the gap, semi‐idealized 3D numerical models calibrated using the mountain river network and the ...

Influence of Temperature and Oxygen Pressure on the Oxidation Process for Preparing Tritium Permeation Barrier

, 2011
In ITER D-T fuel will be used for fusion plasma. Therefore a material capable of acting as a tritium permeation barrier on stainless steel is required. It is well known that thin alumina layer can reduce the tritium permeation rate by several orders of ...

Multi‐Elemental Tracers in the Amerasian Basin Reveal Interlinked Biogeochemical and Physical Processes in the Arctic Ocean Upper Halocline

Global Biogeochemical Cycles, Volume 39, Issue 4, April 2025.
Abstract The physical and biogeochemical properties of the western Arctic Ocean are rapidly changing, resulting in cascading shifts to the local ecosystems. The nutrient‐rich Pacific water inflow to the Arctic through the Bering Strait is modified on the Chukchi and East Siberian shelves by brine rejection during sea ice formation, resulting in a ...

Pregnenolone Sulfate Permeation at the Blood–Brain Barrier is Independent of OATP2B1—In Vivo and In Vitro Insights

Biopharmaceutics &Drug Disposition, Volume 46, Issue 1, Page 33-46, February 2025.
In our study we report that OATP2B1 does not mediate pregnenolone sulfate transport across the blood–brain barrier in rats and in a human cell model, thus suggesting alternative mechanisms involved in pregnenolone sulfate brain uptake. ABSTRACT Sulfated steroids such as pregnenolone sulfate (PregS) are important for neuronal development and cognitive ...
