Heterogeneous Nucleation and Growth of Nanoparticles at Environmental Interfaces

Nucleation and Growth of Gold Nanoparticles

Dislocation Nucleation at Metal-ceramic Interfaces

Ab~act-The ductile vs brittle behaviour of metal-ceramic interfaces is discussed within an atomistic framework, in which the mechanical response of an interfucial crack is assumed to be ultimately controlled by the competition between atomic decohesion and dislocation nucleation ahead of the crack tip. As in later versions of the Rice-Thomson model, this competition may be evaluated in terms of...

Temperature effect on the nucleation and growth of TiO2 colloidal nanoparticles

The nucleation and growth of sol-gel derived TiO2 colloidal nanoparticles have been studied using  experiment and theory as well. In this study, the temperature effect on the formation of TiO2 nanoparticles was discussed and some effective parameters such as the supply rate of solute (Q0), the mean volumic growth rate of stable nuclei during the nucleat...

Heterogeneous nucleation and epitaxial crystal growth of magmatic minerals

Electron backscatter diffraction analysis of dendritic clinopyroxene (cpx) forming in rapidly cooled basalt reveals two features that are unexpected for phases growing from a liquid: (1) helical growth about {010}cpx, the crystallographic b-axis, with incremental rotation (up to 0.4° μm–1) within branch segments and large rotational jumps (10°–46°) between closely spaced branch segments, and (2...
