The review is mainly concerned with the protonation equilibria of biologically active ligands like amino acids, peptides, DNA constituents, and amino acid esters in nonaqueous media. Equilibrium concentrations of proton-ligand formation as a function of pH were investigated. Also, thermodynamics associated with protonation equilibria were also discussed.

varying degrees of water solubility. Some additives (e.g., methyl tertiary-butyl ether and alcohols) are highly soluble. Other components (e.g., benzene, toluene, ethylbenzene, and xylenes) are slightly soluble. Many components (e.g., ndodecane and n-heptane) have relatively low water solubility under ideal conditions. Physical and chemical properties which affect transport and fate of selected...

Steric stabilization by polymers adsorbed on inorganic particle surfaces is gaining more and more attention in both industry and academia because it plays an important role in stabilizing colloidal dispersions. In this review, basic concepts and some related topics about steric stabilization are introduced. In addition the application of steric stabilization in dispersing ceramic particles in n...
