Aggregation Phenomena in Water-in-Oil Emulsions
Langmuir, 1996We report the phase behavior of monodisperse water-in-oil emulsion droplets. We show that depending upon the droplet size, the surfactant concentration within the continuous oil phase, the chemical nature of the oil, and the temperature, the emulsion droplets may remain dispersed or reversibly aggregated.

Five homologous series of α- and α,ω-substituted oligothiophenes up to an undecamer with branched and linear alkyl chains, respectively, are presented. These series are compared with respect to self-organisation in solution and in solid state.

Decreased Aggregation Phenomena in Polyfluorenes by Introducing Carbazole Copolymer Units
, 2001To decrease aggregation phenomena and improve the luminescence of the blue-light-emitting polymer polyfluorene, carbazole units were copolymerized to introduce disorder in the polymer backbone.

On Aggregation Phenomena in Magnetic Fluids by the Tunnel Theory and Monte Carlo Simulations
, 1995We extend the theory of the "tunnel model" to the case of aggregation phenomena in magnetic fluids, which is valid for strong magnetic fields. Our model takes into account cluster-cluster interactions and is used to investigate the aggregation phenomena ...

Aggregation kinetics and precipitation phenomena in poly(phenylisocyanide)
Journal of Polymer Science Part A: Polymer Chemistry, 1997The preparation of N-phenyl-substituted poly(isocyanide) (N-ϕ-PIM) utilizing a Ni(II) catalyst in methanol yields a brown material having a number average molecular weight of about 2000. Analysis of this “as prepared” polymer indicates that a rigid rod structure is present in the derived solid.

Aggregation phenomena in a system of molecules with two internal states
Physical Review E, 2007A model for the aggregation of molecules with two internal states is studied by kinetic Monte Carlo simulations. Molecules are represented by simple beads, discarding all stereochemical specificity. Monomers are placed in a three-dimensional lattice and diffusion processes are simulated, as well as internal state conversions of the molecules.

Environmental implications of aggregation phenomena: Current understanding
Current Opinion in Colloid & Interface Science, 2006This review highlights the current understanding of the aggregation phenomena of importance in Industrial Environmental Protection Technology; namely of particle aggregation in wastewater and gas emission treatment. The wastewaters and gaseous emissions from Forest Industry are our main focus.
