Homogeneous nucleation: reduction of binary nucleation to homomolecular nucleation
Journal of Aerosol Science, 1991Abstract Following the original ideas presented by Volmer, Flood, Neumann and Doring we have included the concept of an average virtual monomer on the thermodynamically consistent version of the classical theory for binary homogeneous nucleation.

Microtubule nucleation is the process in which several tubulin molecules interact to form a microtubule seed. Microtubule nucleation occurs spontaneously in purified tubulin solutions, and molecular intermediates between tubulin dimers and microtubules have been identified.

SUMMARYA new, fundamental stereological principle is described which allows unbiased estimates of absolute structural quantities in arbitrarily shaped structures to be made from observations sampled in arbitrary points on independently isotropic probes. As an introduction to the principle, method(s) are described which lead to assumption‐free estimates

Argon nucleation in a cryogenic nucleation pulse chamber
The Journal of Chemical Physics, 2007Homogeneous nucleation of argon droplets has been measured with a newly designed cryogenic nucleation pulse chamber presented already in a previous paper [Fladerer and Strey, J. Chem. Phys. 124, 16 (2006)]. Here we present the first systematic nucleation onset data for argon measured in a temperature range from 42to58K and for vapor pressures from 0 ...

Heterogeneous Nucleation in Droplet-Based Nucleation Measurements
Crystal Growth & Design, 2013Droplet-based nucleation experiments reveal discrepancies in kinetic and thermodynamic factors. Here we examine how the chemical nature of the water–oil interface, and not the type of the device, used in different set-ups by three different groups impacts nucleation rate and explain discrepancies among lysozyme interfacial energies and pre-exponential ...

Two-dimensional monolayer material of a large number of amphiphiles is transformed into overgrown three-dimensional structures in a state of metastability and supersaturation. This process is described by a theoretical concept and characterised by sensitive experimental techniques.

Nucleation kinetics: runaway nucleation
Materials Science and Technology, 2002AbstractAn analysis of the kinetic critical nucleus size and of 'runaway' nucleation by Nishioka and Maksimov is shown to be flawed and an accurate version of their model is presented. The concept of runaway nucleation is valid only when the thermodynamic critical nucleus size is very small, containing only a few atoms/molecules, and in the regime ...

Crack Propagation, Nucleation and Nucleation Modelling
2021A majority of this book is concerned with describing and analysing the behaviour of contacts, and the effects of local frictional slip. Those results, by themselves, are sufficient to quantify the damping effects afforded, and their influence on limiting the effects of vibration.

For materials capable of attaining two phases, the free energy potential is a non-convex functional of the state variables. Absolute and relative minimizers of this functional are related to stable and metastable states, respectively. Metastability explains the undercooling required for solid nucleation.

BACTERIA AND GALLSTONE NUCLEATION
Australian and New Zealand Journal of Surgery, 1989This preliminary study reports for the first time that there might be a possible association between bacteria and the aetiology of some cholesterol calculi. The gall‐bladder biles from 225 cholecystectomy patients underwent bacteriological and microscopic study.
