In high‐mountain watersheds, the critical zone holds crucial life‐sustaining water stores in
the form of shallow groundwater aquifers. To better understand the role that the critical zone …

Liquid penetration in porous cellulosic materials is crucial in many technological fields. The
complex geometry, small pore size, and often fast timescale of liquid uptake makes the …

Reaction and transport processes in thin layers of between 10 and 1000 µm are important
factors in determining their performance, stability and degradation. In this review, we discuss …

Pore size distribution (PSD) is a fundamental petrophysical parameter for shale formation
evaluation. Nuclear magnetic resonance (NMR), performing as a widely acknowledged …

Low-field nuclear magnetic resonance (NMR) has been widely used to express the pore-
size distributions of conventional and unconventional reservoirs. Based on the equation 1 T …

In headwater catchment, the calibration of hydrological models is complex due to the
scarcity of data in mountainous areas. Here, an innovative methodology is developed to …

Core Ideas Unsaturated saprolite, saturated saprolite, and fractured rock have unique NMR
responses. Surface NMR signals will be dominated by water in saturated saprolite. The …

Nonground eigenvalues are widely disregarded in magnetic resonance relaxation
measurements of porous media due to difficulties involved in their measurement, detection …

Abstract Mudstones of Bayanhua Formation are characterized by high porosity, large
content of swelling clay minerals, and weak cementation due to its late diagenesis in …
