methylsiloxane sol gel systemssmall confined spaceThe organo-siloxane gel with co-continuous structure derived from methyltrimethoxysilane (MTMS) was synthesized in a confined space between parallel plates by inducing spinodal decomposition during sol-gel transition. The resultant gel morphology was 3-...
The sol-gel process is the name given to the process involving a solution or sol that undergoes a sol-gel transition. A solution is a single-phase liquid, and a sol is a stable suspension of colloidal particles. At the transition, the solution or sol becomes a rigid mass. As an overvie...
Steel rebars with oxide scale were immersed in a sol-gel solution (pH = 10) at different temperature, with a fixed concentration ratio (3.89) of Ce3+to Ni2+ions. At lower temperatures, the CNS films (depicted in Fig.1b, c) were poorly formed due to insufficient rates of silane ...
Processes are defined as sol–gel by the transition of colloidal solution to an interconnected gel network (gelation). The further processing stages illustrated are non-redundant and may be combined depending on the specific needs of the application. This section aims to describe the sol–gel ...
usually designed using transition metal fluorides derived from hydrofluoric acid. All these systems are undesirable in terms of their effects on the environment. Alternative systems such as sol-gel derived metal coatings and pre-treatment systems have had ...
Methyl sulfide terminated trans-oligo(p-phenylenevinylene) derivatives(OPVn, nis the numberof phenyl rings) were synthesized, and reversible sol–gel transitionwas observed in a variety of organic solvents. Investigations withUV–vis, fluorescence, and 1H NMR spectroscopy revealedthat aromatic π–π st...
CdxZn1-xS nanocrystals have been prepared by sol-gel method with different content of Cd, and their optical studies are characterized by taking transmittance spectra experimentally. We have theoretically calculated the eigen energy values of the confined electron in ground and excited states as a func...
its glass transition temperature up to ~41%. Therefore, the combined use of FR elements such as silicon and nitrogen and the flexibility of sol-gel routes can facilitate the synthesis of hybrid structures containing well dispersed inorganic phases, which could replace halogen-based flame retardants....
We report on the synthesis of SnO2 nanoparticles and SnO2:CNT hybrids, via a one-step solgel method. Herein, we investigate the influence of the synthesis
In this paper, we focus on the dynamic aspect. The kinetics of the liquid-glass transition is called "aging," while that of the sol-gel transition ... H Tanaka,S Jabbari-Farouji,J Meunier,... - 《Physical Review E Statistical Nonlinear & Soft Matter Physics》 ...
