Time‐dependent (Creep) Compaction in Volcanic Rocks
Abstract Porous volcanic rocks form volcanic edifices and host key geothermal reservoirs worldwide. When subjected to constant stress above dilatancy in the brittle regime, these materials undergo time‐dependent failure known as brittle creep. In the ductile regime, where deformation is compactive, time‐dependent compaction—compaction creep—has been ...

Detecting an Ocean Inside Callisto With Geodetic Measurements From Europa Clipper and Juice
Abstract Determining whether Callisto hosts a subsurface ocean, and the implications for material and energy transport through its hydrosphere, is of high interest to NASA's Europa Clipper and ESA's Juice missions. A recent reanalysis of Galileo magnetometer data strengthens the ocean hypothesis, but definitive confirmation awaits new measurements.

Evolution of P‐wave Anisotropy as an Indicator of Pre‐failure Deformation in Shale
Abstract Understanding the multiscale mechanical behavior of clay‐rich rocks is critical for assessing fault reactivation and the long‐term integrity of underground waste repositories. This study investigates the evolution of microdeformation in Tournemire's shale samples under compressive stress by integrating high‐resolution imaging (from an ...

Magnetic particles are organized into layered architectures by combining shear flow and magnetic fields, with the resulting structures governed by appropriate Mason numbers. The programmed assemblies provide spatial guidance for cell placement, linking field‐controlled self‐assembly, flow‐induced structuring and biological organization.

Hierarchical Twin Networks Enable Exceptional Strength and Fracture Toughness in Titanium
A commercial‐purity titanium with hierarchical ultrafine twin structures delivers an exceptional combination of fracture toughness (KJIc) of 187 MPa·m1/2 and specific yield strength of 140 MPa·cm3·g−1, in which pre‐engineered high‐density twin boundaries stimulate massive and

Numerical Simulation of Water‐Rock Reaction for CO2 Sequestration in Sandstone Reservoir
Based on the TOUGHREACT software, the spatiotemporal evolution laws of parameters including gas–liquid saturation, mineral composition, ionic composition, temperature and pH during CO2 injection under different injection‐production well spacing conditions were systematically investigated.
