Microcracks closure effects in initially orthotropic materials
, 2013 Microcracking is one of the basic mechanisms of inelastic deformation for a large class of anisotropic materials such as brittle matrix composites. Even at fixed microcracks density, the macroscopic behavior of these materials is very complex due to the ...

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
Advanced Functional Materials, EarlyView.In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Microcracks and Radioactive Waste Disposal
, 1982 Examination of microcracks in crystalline rocks has shown that the open microcracks form a spatially continuous network that communicates with larger openings. The open cracks become filled with new minerals that often contain U and LREEs.

Tantalum–Palladium Ultrathin Resistance Hydrogen Sensor
Advanced Functional Materials, EarlyView.Nanoconfined Ta‐alloy thin films enable fast, reversible hydrogen sensing by suppressing unwanted phase transitions. A Ta0.88${\rm Ta}_{0.88}$Pd0.12${\rm Pd}_{0.12}$ sensing layer delivers hysteresis‐free detection from ppb to 100% H2${\rm H}_2$ at room temperature.
