Insights Into the Mechanisms Controlling the Residual Strength of Bio‐cemented Sands

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 6, Page 2711-2726, 25 April 2026.
ABSTRACT Microbially induced carbonate precipitation (MICP) is an emerging technique for enhancing the mechanical properties of granular soils. Although several experimental studies have reported increased shear strength in MICP‐treated soils at both peak and residual states, other findings have shown reductions in residual strength compared to ...

CO2 Exsolution and Residual Trapping Influenced by Heterogeneity During Imbibition in Conglomerates: A Core‐Scale Multiphase Flow

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Although conglomerates composed of clasts and matrix are commonly interbedded with sandstones at geologic CO2 storage sites, their residual trapping behavior remains poorly understood. This study investigates the influence of clast‐induced heterogeneity on residual CO2 trapping during water imbibition, using two natural conglomerate cores from
