Collagen aggregation phenomena
Biopolymers, 1966AbstractThree processes by which tropocollagen units associate to yield highly specific aggregates have been examined. From the temperature coefficients of the amounts aggregated it is concluded that the complex “native” aggregation is endothermic, whereas both end‐to‐end and lateral aggregation are exothermic.

Aggregation phenomena in telechelic star polymer solutions
Physical Review E, 2009Telechelic star polymers are macromolecules with functionalized, mutually attractive end groups. We employ computer simulations on a lattice to investigate the phase behavior of trifunctional telechelic stars as a function of the fraction lambda of attractive terminal monomers.

Light scattering studies of aggregation phenomena
Physica A: Statistical Mechanics and its Applications, 1995Abstract We present recent results in the field of colloidal aggregation. We first present static light scattering data of aggregation in intermediate regimes between RLCA and DLCA. In particular, we show that working with dense solutions, new and unexpected features are observed.

Oxygen Aggregation Phenomena in Silicon
MRS Proceedings, 1987ABSTRACTOxygen precipitation in Czochralski silicon heated in the range 400–1050°C is reviewed. For T≥525° C, Si02 particles form at the normal diffusion rate and there is generation of self-interstitials. At the lower temperatures, the existence of the interfacial energy causes an apparent increase in the solid solubility as the agglomerates become ...

Aggregation phenomena and fractal structures
Physica A: Statistical Mechanics and its Applications, 1986Abstract In disordered aggregation processes fractal structures appear in a natural way. Many of their properties can be characterised in terms of scaling and numerous models have been introduced to describe different physical situations. “Clustering of Clusters” is a model applicable to several growth processes in colloid science and elsewhere.

Dynamic Scaling in Aggregation Phenomena
1985The dynamics of the diffusion-limited cluster-cluster aggregation model (CCA) is reviewed through the temporal evolution of the cluster size distribution ns(t), which is the number of clusters of size s at time t. In recent studies it was shown that the results of the Monte-Carlo simulations can be well represented by a dynamic scaling function of the ...

Fluctuations and scaling in aggregation phenomena
Physical Review B, 2000We introduce a method which enables us to isolate different sources of fluctuations during a typical aggregation process. As an example, we focus on the evolution of islands during irreversible submonolayer epitaxy. We show that only spatial fluctuations in island nucleation are required to produce the scaling of their size distribution as determined ...

Protein Folding and Aggregation Phenomena
AIP Conference Proceedings, 2003A simple lattice protein model is used to study the effects of aggregation phenomena on protein folding. Folding kinetics of non‐isolated protein molecules is studied: different molecules can interact each other and, in competition with folding, aggregation (formation of a dimer) can occur.

Aggregation Phenomena in Lignin
The present chapter describes a survey of the aggregation phenomena occurring during lignin nanostructures formation, the main variables affecting them, the most common strategies for their preparation and their applications. The interactions affecting the conformation of single lignin chains in a specific solvating environment pertain to cohesive ...Cestari, Chiara +2 more
