Nanoscale Studies on Aggregation Phenomena in Nanofluids

2018
Understanding the microscopic dispersion and aggregation of nanoparticles at nanoscale media has become an important challenge during the last decades. Nanoscale modeling techniques are the important tools to tackle many of the complex problems faced by engineers and scientists.

Aggregation phenomena in photobicyclised pyridinium salts

New Journal of Chemistry, 2017
Absorption and emission spectra of PQPBF 4 and BPDTQClO 4 in water provide evidence, supported by theoretical calculations, of H-aggregation in this solvent.

Aggregation Phenomena in Water-in-Oil Emulsions

Langmuir, 1996
We 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.

On the nature of interactions associated with aggregation phenomena in the mouth

Journal of Dentistry, 1979
Abstract The evidence to support therole of acalcium-bridging mechanismin aggregation phenomena in the mouth is discussed in relation to additional evidence to the contrary. Other possible aggregating mechanisms are discussed and a hypothesis is presented to support the role of the hydrophobic interaction in these processes.

Statistical physics models of aggregation phenomena

Journal of Physics A: Mathematical and General, 1997
Summary: Aggregation phenomena of elementary particles into clusters is one of the most fascinating and challenging problems of statistical physics. Here we adopt a stochastic approach for the modelling of these phenomena. More precisely, we formulate the problem as follows (which we shall refer to as the `cavity' method): given a population of \(N ...

Freeze-and-Thaw Phenomena in Concretes and Aggregates

1970
This report summarizes several years of research relating to damage to concrete and aggregates undergoing freezing and thawing. Basic principles involving freezing and attendant pressures are considered. Application of these principles to the evaluation of concrete was accomplished in experiments on concrete having low and high air contents.

A Discrete Model for Spatially Aggregating Phenomena

1986
Abstract The objective of the present paper is to numerically study the behavior of a solution of a mathematical model for spatially aggregating phenomena of population. For this purpose, we propose a discrete model, which preserves important properties of the continuous model with the aid of its nonlinear artificial viscosity term.
