Fluctuating Bond Aggregation: A Model for Chemical Gel Formation.
نویسندگان
چکیده
The Diffusion-Limited Cluster-Cluster Aggregation (DLCA) model is modified by including cluster deformations using the bond fluctuation algorithm. From 3d computer simulations, it is shown that, below a given threshold value cg of the volumic fraction c, the realization of all intra-aggregate bonding possibilities prevents the formation of a gelling network. For c > cg, the sol-gel transition occurs at a time tg which, in contrast to DLCA, doesnot diverge with the box size. Several results are reported including small angle scattering curves and possible applications are discussed. PACS numbers: 61.43.Bn, 61.43.Hv, 82.70.Gg. Typeset using REVTEX

Influence of heat and pH on structure and conformation of whey proteins
22 23 The aim of this study was to understand the fundamental interactions responsible for 24 aggregation of whey proteins (WPs) at pH 6 and 3 during heating at 140 oC for 30 s in the 25 presence of different acidulants. The conformational changes in the various heat-treated WP 26 dispersions were studied using chemical bond blockers and analysed using differential 27 scanning calorimeter therm...
متن کاملConnecting irreversible to reversible aggregation: time and temperature.
We report molecular dynamics simulations of a gel-forming mixture of ellipsoidal patchy particles with different functionality. We show that in this model, which disfavors the formation of bond-loops, elapsed time during irreversible aggregation--leading to the formation of an extended network--can be formally correlated with equilibrium temperature in reversible aggregation. We also show that ...
متن کاملWeakly Interacting Colloid Polymer Mixtures
This thesis explores the physics of weakly interacting colloid-polymer mixtures. Colloid-polymer mixtures can consist of two kinds of interactions; depletion and adsorption. Both interactions can lead to colloidal aggregation and formation of space spanning gels that can bear stress. Depending on the range of the attractive interaction, depletion gels bear stress by two mechanisms; bond-stretch...
متن کاملHeat-induced aggregation of recombinant erythropoietin in the intact and deglycosylated states as monitored by gel permeation chromatography combined with a low-angle laser light scattering technique.
Aggregate formation of recombinant human erythropoietin (r-EPO) on heat-treatment was followed by gel permeation chromatography combined with a low-angle laser light scattering technique under various conditions with respect to pH and salt concentration in order to provide basic knowledge about the change strictly required to be monitored for medicinal proteins. When heated at 60 degrees C at n...
متن کاملRe-entrant phase diagram and pH effects in cross-linked gelatin gels.
Experimental results have shown that the kinetics of bond formation in chemical cross-linking of gelatin solutions are strongly affected not only by gelatin and reactant concentrations but also by the solution pH. We present an extended numerical investigation of the phase diagram and of the kinetics of bond formation as a function of the pH, via Monte Carlo simulations of a lattice model for g...
