Computational analysis of homogeneous nucleation and droplet growth applied to natural gas separators

open access: yesRevista UIS Ingenierías, 2021
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

Floristic Composition Analysis of Soil Transposition in a Seasonal Forest in Rio Grande do Sul, Brazil

open access: yesFloresta e Ambiente, 2019
This study aimed to identify the floristic composition and density of a seed bank transposed from a Seasonal Forest fragment in Rio Grande do Sul. The seed bank of the (BSI) fragment center and edge (BSII) of another forest fragment was also evaluated ...

Studying Ice with Environmental Scanning Electron Microscopy

open access: yesMolecules, 2021
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]

open access: yes, 2004
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]

open access: yes, 2014
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]

open access: yesJournal of Nanostructures, 2018
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

open access: yes, 2002
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 ...
