Hierarchical Assembly Strategy and Multiscale Structural Origin of Exceptional Mechanical Performance In Nacre
… amorphous aggregation. The underlying physics mechanism why the aragonite nanoparticles choose highly-oriented attachment as its crystallization pathway is rationalized in terms of thermodynamics. The aragonite nanoparticle order-disorder transformation can be triggered by high temperature and …

Shock isolation using switchable stiffness
… and the analysis is mainly concerned with the energy dissipation mechanism used to suppress residual vibration. As in the first stage of shock isolation, two models are considered. Optimum configurations and stiffness changes are identified for both the shock response reduction and the decay of …

Phase morphology and fracture toughness of CNT/polytherimide modified epoxy polymer nanocomposites as matrices for advanced CFPR composites
… first part of this work explores the underlying mechanism of the formation of phase-separated thermoplastic phases with distinct sizes, based on the two types of epoxy resins (bifunctional and tetrafunctional), and implications on fracture toughness. It is shown that the higher viscosity and …

Charge and excitation-energy transfer in time-dependent density functional theory
Learning about and understanding the mechanisms and pathways of charge and excitation-energy transfer of natural molecular complexes is a promising approach for the tailored design of new artificial energy-converting materials. Therefore, next to extensive experimental investigations, a …

Effect of specimen geometry and test configuration on the fracture process zone for asphalt materials
… curve that is characterized using the fracture energy (FE), strength, and post-peak slope. The microstructural response refers to the deformation occurring in the fracture process zone (FPZ). FPZ is the region surrounding the notch tip that develops micro cracks before a macro crack is observed. …
