Anaerobic Corrosion Phenomena of Cast Iron and Copper in Artificial Groundwater at Elevated Temperature

Materials and Corrosion, Volume 77, Issue 8, Page 1262-1277, August 2026.
This study examines corrosion of copper and cast iron as candidate canister materials for high‐level radioactive waste disposal in contact with bentonite suspension. The influence of three electrolyte compositions on corrosion behavior under repository‐relevant conditions is assessed.

Insights Into the Temperature‐Dependent Oxidation Mechanism of Metallic Cerium in H2O‐N2 Atmospheres

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Metallic cerium (Ce), a widely used surrogate for actinide metals, enables mechanistic studies of reactions in complex gas environments under controlled and safer laboratory conditions. Here, the oxidation behavior of Ce in H2O‐N2 mixed atmospheres was investigated from 200°C to 350°C using in situ thermogravimetry–mass spectrometry, in situ X‐

Modeling Transient Flow in Heterogeneous Aquifers With the Mixed Pressure‐Velocity Formulation of Physics Informed Neural Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Physics‐Informed Neural Networks (PINNs) have emerged as a powerful framework for modeling groundwater flow using deep learning neural networks, particularly in scenarios where traditional data‐driven approaches are limited by the scarcity of data.

Overall Prediction of Breakthrough Curves in Fracture Networks Using Graph‐Based Simulation and Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Discrete fracture network (DFN) models are widely used to simulate fluid and solute transport through fracture networks that serve as their preferential pathways. In DFN models, fractures are generated stochastically based on fracture properties.

Implicit Neural Representation to Improve the Resolution of 3D Electrical Resistivity

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Electrical resistivity tomography (ERT) is a subsurface imaging geophysical technique. Traditional ERT inversion methods, such as smoothness‐constrained least‐squares approaches, often suffer from discretization artifacts when reconstructing electrical resistivity from resistance measurements.

A Kolmogorov–Arnold Surrogate Model for Chemical Equilibria: Application to Solid Solutions

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The computational cost of geochemical solvers is a challenging matter. For reactive transport simulations, where chemical calculations are performed up to billions of times, it is crucial to reduce the total computational time. Existing publications have explored various machine learning approaches to determine the most effective data‐driven ...

Salivary estradiol and progesterone across the menstrual cycle: Association and agreement with serum concentrations

Physiological Reports, Volume 14, Issue 15, August 2026.
Abstract Saliva provides a noninvasive alternative to serum for serial sampling of estradiol and progesterone. This study examined salivary estradiol and progesterone patterns and the relationship between salivary and serum estradiol, progesterone, and the estradiol to progesterone ratio (E2:P) across the menstrual cycle (MC) in physically active ...

Actinide 4,4′‐Bipyridine‐N,N′‐Dioxide Coordination Polymers: Cationic Framework Structures Templated by Dicyanoaurate and Tetracyanoaurate Counterions

European Journal of Inorganic Chemistry, Volume 29, Issue 21, 25 July 2026.
Th4+ or UO22+ actinides, neutral bipyridine‐N,N’‐dioxide ligands, and anionic cyanoaurate linkers are combined to generate a family of four coordination polymers. ‘Truss bridge’ and square grid cationic frameworks are yielded when using [Au(CN)2]− or [Au(CN)4]−, respectively, indicating a templating effect guided by either aurophilic interactions ...
