Fluctuating Bond Aggregation: A Model for Chemical Gel Formation.
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 o...
متن کاملParameter free aggregation model for soot formation
In this article we present a parameter free aggregation model for soot formation. Each soot particle is represented as a fractal aggregate that can be described by its total volume, total surface, and number of hydrogenated sites on its surface. The moments of the joint Probility Density Function (PDF) of these three quantities are solved using the Direct Quadrature Method of Moments (DQMOM). T...
متن کاملConstant bond breakup probability model for reversible aggregation processes.
Reversible aggregation processes were simulated for systems of freely diffusing sticky particles. Reversibility was introduced by allowing that all bonds in the system may break with a given probability per time interval. In order to describe the kinetics of such aggregation-fragmentation processes, a fragmentation kernel was developed and then used together with the Brownian aggregation kernel...
متن کاملA COGNITIVE STYLE AND AGGREGATION OPERATOR MODEL: A LINGUISTIC APPROACH FOR CLASSIFICATION AND SELECTION OF THE AGGREGATION OPERATORS
Aggregation operators (AOs) have been studied by many schol- ars. As many AOs are proposed, there is still lacking approach to classify the categories of AO, and to select the appropriate AO within the AO candidates. In this research, each AO can be regarded as a cognitive style or individual dierence. A Cognitive Style and Aggregation Operator (CSAO) model is pro- posed to analyze the mapping ...
متن کاملContact formation dynamics: Mapping chemical bond formation between a molecule and a metallic probe.
We present a study that maps out chemical bond formation between a Pt-inked probe and a single 1,3-cyclohexadiene (1,3-CHD) molecule on Si(100). By separating the mechanical and electronic contributions to the current during the approach to contact, we show that there are significant forces between the probe and the C=C of the molecule and we track the relaxation of the molecule, the emergence ...
