Experimental Proof to Natural Hydrogen Generated Through Serpentinization of Olivine at Room Temperature and Ambient Pressure With Mechanochemistry

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
This work shows experimentally the possibility of serpentinization (main mechanism of natural hydrogen) at room temperature and ambient pressure, which may provide the rapidly growing hydrogen economy with inspirations to explore new natural hydrogen deposits and new methods for hydrogen production. Natural hydrogen, or “white hydrogen,” is a promising

Multiphysics Monitoring of Capillary, Electrical, and Elastic Responses During Drainage and Imbibition at Reservoir Conditions

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Capillary pressure‐saturation relationships are crucial for geo‐energy recovery, and increasingly, for environmental applications. However, for reservoir‐relevant pressure and temperature conditions, only limited data sets are available from special core analysis in laboratory (SCAL) studies.

Hyperspectral Fingerprinting of Dune Sediments Across the Arabian Peninsula: Insights Into Sediment Provenance and Transport Pathways From NASA's EMIT Data

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Arabian Peninsula encompasses one of the world's most extensive aeolian systems, yet the provenance and transport history of its dune sediments are not well understood. Using hyperspectral data from NASA's Earth Surface Mineral Dust Source Investigation (EMIT), we mapped mineral compositions and abundance patterns across dune fields and ...

Comparison of Soil Mineralogy From EMIT Imaging Spectroscopy and Ground‐Based Measurements in the Deserts of Southern California

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract The highly variable spatial composition of desert soils remains a major source of uncertainty in estimates of dust radiative forcing. Existing soil mineralogy data sets used in climate models are limited by sparse ground observations and coarse spatial resolution.

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.
