Adsorption of oppositely charged species (e.g., protons, specifically adsorbing ions, surfactants, or polyelectrolytes) may destabilize a particle suspension by charge neutralization or stabilize it by buildup of charge, leading to a fast aggregation near the charge neutralization point, and slow aggregation away from it.
Hydrophobic collapse is a proposed process for the production of the 3-D conformation adopted by polypeptides and other molecules in polar solvents. The theory states that the nascent polypeptide forms initial secondary structure ( ɑ-helices and β-strands ) creating localized regions of predominantly hydrophobic residues .
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
In geology, consolidation is used in several senses: Lithification, the overall process of conversion of loose sediments to solid rock. [1] [2] Any other process in which loose or fluid material becomes solid rock, such as solidification of magma. [1]
In the second - the hydrophobic collapse model - the formation of a loosely packed tertiary structure precedes secondary structure acquisition. [2] A nucleation-condensation mechanism involving concomitant formation of short and long-range interactions combines features of both extreme models and thereby represents a unifying mechanism of ...

Consolidation is a great way to stay on top of your monthly payments. Federal student loan payments have resumed, so you must start worrying about due dates again. And if you have federal loans ...
So, in some sense, graphite intercalation compounds are salts. Intercalation is often reversible: the inserted ions can be removed and the sheets of carbon collapse to a graphite-like structure. The properties of graphite intercalation compounds differ from those of the parent graphite. [1] [2]
