A natural gas droplet is generated at certain thermodynamic conditions through three stages: supersaturation, where the gas has more molecules than it should have in equilibrium, forming “embryos” of liquid phase; nucleation, where embryos form groups of

Studying Ice with Environmental Scanning Electron Microscopy
Scanning electron microscopy (SEM) is a powerful imaging technique able to obtain astonishing images of the micro- and the nano-world. Unfortunately, the technique has been limited to vacuum conditions for many years.

Nucleation in binary polymer blends: Effects of foreign mesoscopic spherical particles [PDF]
We study nucleation in binary polymer blends in the presence of mesoscopic spherical particles using self-consistent field theory, considering both heterogeneous and homogeneous nucleation mechanisms.

Nucleation of a new phase on a surface that is changing irreversibly with time [PDF]
Nucleation of a new phase almost always starts at a surface. This surface is almost always assumed not to change with time. However, surfaces can roughen, partially dissolve and change chemically with time.

Dimethylamine Controlled Sol-Gel Process to Grow ZnO Nanorods [PDF]
ZnO nanorods were prepared using dimethylamine (DMA) controlled Sol-Gel process. Dimethylamine was added as an additive to control the sol-gel process for growing ZnO nanorods.

The uphill turtle race: on short time nucleation probabilities
The short time behavior of nucleation probabilities is studied by representing nucleation as diffusion in a potential well with escape over a barrier. If initially all growing nuclei start at the bottom of the well, the first nucleation time on average ...
