Nanovoid nucleation by vacancy aggregation and vacancy-cluster coarsening in high-purity metallic single crystals [PDF]
, 2011 A numerical model to estimate critical times required for nanovoid nucleation in high-purity aluminum single crystals subjected to shock loading is presented. We regard a nanovoid to be nucleated when it attains a size sufficient for subsequent growth by

Advanced Engineering Materials, EarlyView.Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

A 3D tomographic EBSD analysis of a CVD diamond thin film
Science and Technology of Advanced Materials, 2008 We have studied the nucleation and growth processes in a chemical vapor deposition (CVD) diamond film using a tomographic electron backscattering diffraction method (3D EBSD).

Modulating Nucleation by Kosmotropes and Chaotropes: Testing the Waters
Crystals, 2017 Water is a fundamental solvent sustaining life, key to the conformations and equilibria associated with solute species. Emerging studies on nucleation and crystallization phenomena reveal that the dynamics of hydration associated with mineral precursors ...

A Brownian Model for Crystal Nucleation
, 2013 In this work a phenomenological stochastic differential equation is proposed to model the time evolution of the radius of a pre-critical molecular cluster during nucleation (the classical order parameter).

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

A new parametrization for ambient particle formation over coniferous forests and its potential implications for the future [PDF]
, 2009 Atmospheric new particle formation is a general phenomenon observed over coniferous forests. So far nucleation is either parameterised as a function of gaseous sulphuric acid concentration only, which is unable to explain the observed seasonality of ...

Loss of control in pattern-directed nucleation: a theoretical study
, 2008 The properties of template-directed nucleation are studied close to the transition where full nucleation control is lost and additional nucleation occurs beyond the pre-patterned regions.

Silicon electrodeposition in molten fluorides [PDF]
, 2011 Silicon nucleation process was investigated in molten NaF-KF (40-60 mol%) on silver electrodes in the 820-950°C temperature range in order to optimize silicon coating operating conditions.
