Tube-to-tube sheet joints fabricated using tube expansion and diffusion bonding met the engineering requirement, tube rupture against mechanical pull-out, set for this study.
Thus, the pheripheric position of the Ethiopian and South Eastern Italian (European) haplotypes suggests that the high values of variance registered in these regions likely reflect the stratification of different migratory events, some of which occurred before the expansion and diffusion of the lineage outside the Middle Eastern area.
The YS structured materials with tailored interior space, shape and components can synergetically relieve volume expansion and facilitate rapid diffusion and electron transportation.
A differential quasi-one-dimensional flame model which accounts for flame curvature, lateral flow expansion, and cross-stream diffusion is formulated.
The analysis shows that three mechanisms contribute to the enhancement of the displacement speed: a chemical mechanism associated with modifications to the reaction zone structure, lateral flow expansion, and cross-stream diffusion.
As a binder-free anode of lithium-ion battery, the nanodendritic structure of C-MnO accommodates the huge volume expansion and shortens the diffusion length for lithium ion and electron, rGO sheets prevent C-MnO nanodendites from aggregation and offer a good electronic conduction.
Propane fuel without and with dilution (40% helium and argon, by volume) was used, while the reaction scheme adopted was the one-step irreversible Arrhenius kinetics (see Li et al., Combust. Flame 157 (2010) 1484 1495) which proved successful in predicting the flame lift-off height and effects of thermal expansion and multi-component diffusion.
The expansion boosts the intercalation and diffusion of alkaline ions (Li+ and Na+) in layered MoS2.
The strengthening mechanisms in adherence are addressed and can be related to the crystal structure, thermal expansion coefficient, surface roughness, and diffusion layer between the coating and the substrate.
Several functions are also required for practical coatings: self-healing, equivalent thermal expansion, thermal barrier, phase stability, and diffusion barrier.
The original lamination structure of the MCMBs was completely destroyed for volume expansion of the resultant materials and diffusion of fluorine/nitrogen mixed gases.
