The low‐field nuclear magnetic resonance (NMR) measurements are applied to investigate the seepage characteristics of the single rough joint. The purpose of this paper is to investigate the seepage characteristics of granite specimens with single‐joint channel under the different roughness, confining pressures and seepage pressures.

Numerical Investigation of Methane Transport Within and Around Evolving Cracks
A validated model shows that natural gas leakage induces soil deformation and forms three key cracks. When diffusion is low, methane moves mainly along the primary crack, demonstrating how natural fractures reshape pathways and significantly enhance methane migration.

Immersed Boundary Projection Method for Boundaries With Slip Velocities
A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Bending Fatigue Evaluation and Failure Modes of Ultra‐Thin Silicon Chips on Flexible Substrates
This study investigates the fatigue lifetime of 20‐μm‐thick chips under bending deformation. Three failure modes are identified: metal pad wearing, metal stress migration, and gold wire break. The underlying mechanisms are analyzed through micro‐scale characterization, and temperature effects on fatigue lifetime are explored.

From hydrogels to eutectogels: Emerging platforms for stretchable electronics
The transition of wearable electronics toward long‐term reliability requires materials that resist dehydration without sacrificing tissue‐like softness and ionic conductivity. Eutectogels fulfill these demands by immobilizing deep eutectic solvents within tailored polymer networks.
