Theory of the stability of strongly charged lyophobic sols and of the adhesion of strongly charged particles in solutions of electrolytes

Virus transport in physically and geochemically heterogeneous subsurface porous media

“…If virus and grain surface charges are known, virus attachment behavior can be predicted, at least qualitatively, using classic DLVO theory (Derjaguin and Landau, 1941;Verwey and Overbeek, 1948). Conditions that reduce the electrostatic repulsion between viruses and grains, like low pH, presence of divalent cations, and high ionic strength, favor attachment (Zerda et al, 1985;Penrod et al, 1996).…”

The role of cell-surface interactions in bacterial initial adhesion and consequent biofilm formation on nanofiltration/reverse osmosis membranes

“…Only when the cell and surface are in close proximity do short-range interactions become significant (including hydrogen bonding as well as hydrophobic interactions). The theoretical approaches for describing these interactions usually involve DLVO or XDLVO theory and are reviewed in detail elsewhere [15][16][17][18]. This theory has been applied in investigations of bacterial adhesion on membranes, in controlled environments, by taking into account the membrane contact angle, roughness and surface charge, as well as the bacteria cell wall properties [19][20][21].…”

Contrasting Roles Of Natural Organic Matter On Colloidal Stabilization And Flocculation In Freshwaters

“…The electrostatic interaction between particles of similar primary charge always produces a repulsive force for which the repulsive potential energy, V R , increases in magnitude as the distance separating the particle is decreased. For spherical colloidal particles, Derjaguin (Derjaguin and Landau 1941) showed that the energy of interaction, V R , between two identical spheres of radius, a, can be expressed by :…”
