Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Influence of Complex Lithology Distribution on Fracture Propagation Morphology in Coalbed Methane Reservoir

Applied Sciences
The mineral composition in coalbed methane (CBM) reservoirs significantly influences fracture morphology, making the description of reservoir heterogeneity challenging. This study develops a fracture propagation model for CBM reservoirs that incorporates

Crack morphology models for fracture toughness and fatigue strength analysis

, 2019
Planar cracks represent an approximation, largely adopted in fracture mechanics and fatigue problems, of the physical reality, where cracks feature complex geometric morphologies related to material microstructure, residual stresses, material properties ...

Biomineral‐Inspired Organic/Inorganic Colloidal Liquid‐Crystalline Hybrids for Photoresponsive Adhesion

Advanced Functional Materials, EarlyView.
A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.

Classification and pathoanatomy of posterior malleolus fracture based on posterior malleolus-associated ligaments and ankle stability

Journal of Orthopaedic Translation
Background: The clinical significance of previous posterior malleolus fracture classifications is limited because they are mainly based on fracture morphology. On the basis of posterior malleolus-associated ligaments and ankle stability, injury mechanism,

Fracture Toughness and Fracture Morphology of Sintered Tungsten Alloys.

Journal of the Society of Materials Science, Japan, 1993
Fracture toughness tests of W-Ni-Fe sintered tungsten alloys with various volume fractions of tungsten particles were carried out under various loading rates. Fracture toughness of the sintered tungsten alloys decreased with increasing volume fraction of tungsten particles.
