The effect of salts on the solvent-induced interactions between hydrophobic particles dispersed in explicit aqueous solution is investigated as a function of the salt's ionic charge density by molecular dynamics simulations. We demonstrate that aggregates of the hydrophobic particles can be formed or dissolved in response to changes in the charge density of the ions. Ions with high charge densi...
Erodibility as a dynamic property of soil depends on the soil`s aggregate stability and initial large particles percentage which are resistant to erosion. One of the effective factors on soil erosion is soil aggregate stability and its efficient components. Due to the presence of stabilized sand seas which is affected via different plantation development of Haloxylon in the desert area of Tayba...
In regions of deep tropical convection, ice particles often undergo aggregation and form complex chains. To investigate the effect of the representation of aggregates on electromagnetic scattering calculations, we developed an algorithm to efficiently specify the geometries of aggregates and to compute some of their geometric parameters, such as the projected area. Based on in situ observations...
It is generally assumed that crystallization begins with a small, crystalline nucleus. For proteins this paradigm may not be valid. Our numerical simulations show that under conditions typically used to produce protein crystals, small clusters of model proteins (particles with short-range, attractive interactions) cannot maintain a crystalline structure. Protein crystal nucleation is therefore ...
When colloidal particles are suspended in a liquid, the particle suspension can be stable or unstable. Particles in a stable suspension are dispersed individually. In an unstable suspension, particles aggregate. This means that particles stick to each other, first they form doublets, and later larger aggregates. When there are only small aggregates, one refers to early stages of the aggregation...
