High‐Density Iron Nanostructures Grown on Electrospun PVA/Pectin Fibers via Seed‐Mediated Strategy for As(V) Remediation

open access: yesSmall Methods, Volume 10, Issue 18, 23 September 2026.
A seed‐assisted anisotropic growth strategy enabling unprecedented iron loading and controlled anisotropic nanostructure formation on electrospun PVA/pectin nanofibers is presented. By decoupling nucleation and growth through sequential Fe2+ then Fe3+ doping, it achieves a 12‐fold increase in accessible iron content, producing rice‐grain‐like ...

A review of numerical methods for flow and transport modeling in the vadose zone

open access: yesVadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Accurate modeling of subsurface flow and transport processes in the vadose zone, governed by the Richards equation and advection‐dispersion equation, respectively, poses major numerical challenges due to the strong nonlinearity of the governing partial differential equations, spatial heterogeneity and anisotropy of the media parameters, and ...
