Kinetics of gelation growth in a sol-gel transition by a computer-simulation model

A computer simulation model is used to study the kinetics of gelation of a low concentration of bifunctional (C~) and tetrafunctional (C~) monomers on a simple cubic lattice. The mobilities of the monomers and the micragel panicles are considered. Monomers react with their neighbors with a certain probability after hopping with a fixed number of steps. Growth of the concentration of saturated b...

Thermoluminescece properties of BeO:Mg nanoparticles produced by sol-gel method

Beryllium  oxide  (BeO)  nanopowder  was  synthesized  using  sol-gel method  and  the  effects  of  changes of  chemical  reagents  were investigated.  Because  of  tissue  equivalence  and  other  outstanding thermoluminescence  (TL) properties of  the bulk material  in X and γ dosimetry, the applicability of this nanostructure in TL dosimetry was studied  following  irradiation to  the 137 C...

Temperature and solvent-dependent morphological sol gel transformation: an in situ microscopic observation.

A thermoreversible self-assemble process from gel (fiber) to sol (vesicle) state in the system alkylamine-ethylene glycol is for the first time monitored by in situ polarized optical microscopy, XRD, (1)H NMR, SEM, SAXRD, FTIR and drop shape analysis. It is found that the solvent molecules are intercalated with alkylamine molecules to form the organogel and vesicle structures. A model based on ...
