Effects of Clay Content on Non-Linear Seepage Behaviors in the Sand–Clay Porous Media Based on Low-Field Nuclear Magnetic Resonance

open access: yesWater
Clay is widely encountered in nature and directly influences seepage behaviors, exerting a crucial impact on engineering applications. Under low hydraulic gradients, seepage behaviors have been observed to deviate from Darcy’s law, displaying a non ...

Polymersome Crack Film and Its Templating Function in Silica and Gold Deposition

open access: yesMacromolecular Chemistry and Physics, Volume 227, Issue 13, 15 July 2026.
Polymersome dispersion self‐assembled from PEI‐b‐PPOZ block copolymer in aqueous media can be drop‐cast onto substrates to give cracked films. The cracked film served as an effective catalytic template for the hydrolytic polycondensation of TMOS, producing silica‐coated films that retained the original crack pattern. In addition, gold deposition on the

Investigation and quantification of hydraulic gradient and precipitation effect on flow and solute transport in the capillary fringe and saturated zone

open access: yesVadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract Although the capillary fringe (CF) zone plays a critical role in water flow and solute transport within porous media, its influence is often neglected in numerical models. In this research, the HYDRUS‐2D model was validated with data from a physical experiment.

Quantifying Thermo‐Fluid‐Chemical Coupling: Advection Governs Multi‐Phase Zonation and Self‐Sealing in a Hydrate‐Cold Seep System

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Deep fluid advection fundamentally governs the thermal‐fluid‐chemical evolution and distribution of hydrate‐cold seep systems. However, coupled relationships between deep fluid and shallow multiphase dynamics remain inadequately constrained.

High Childhood Leukemia Mortality Rates in Mexico Associated to Water Contamination in Areas of Oil and Gas Extraction

open access: yesGeoHealth, Volume 10, Issue 7, July 2026.
Abstract Acute lymphoblastic leukemia (ALL) is the leading cause of death in Mexican children, yet water‐mediated environmental pathways remain largely unexplored as contributors to its spatial distribution. We analyzed ALL mortality records for individuals aged 0–19 years across all Mexican municipalities from 2003 to 2023, using publicly available ...

Two-phase inertial flow in homogeneous porous media: A theoretical derivation of a macroscopic model [PDF]

open access: yes, 2008
The purpose of this article is to derive a macroscopic model for a certain class of inertial two-phase, incompressible, Newtonian fluid flow through homogenous porous media. Starting from the continuity and Navier–Stokes equations in each phase β and γ ,

Simulation procedure of unconfined seepage with an inner seepage face in a heterogeneous field

open access: yes, 2013
An inner seepage face phenomenon is given and a numerical simulation procedure has been developed. It may appear at the interface of two materials when an unconfined seepage flows from a porous media to a coarser porous media with a higher permeability ...

A CE/SE Scheme for Flows in Porous Media and Its Applications [PDF]

open access: yes, 2009
In this paper, a new computational scheme for solving flows in porous media was proposed. The scheme was based on an improved CE/SE method (the space-time Conservation Element and Solution Element method).
