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...

The enthalpy of hydrogen-bond formation between guanine (G) and cytusine (C) in o-dichlorobenzene and in chloroform at 25°C has been determined by direct calorimetric measurement. We derivatized 2’-deoxyguanosine and 2‘-deoxycytidine at the 5’and 3’-hydroxyls with triisopropylsilyl groups; these group increase the solubility of the nucleic acid bases in nonaqueous solvents. Such derivatization ...

Platinum group metals (PGMs) are important for the manufacture of advanced materials in field catalysts and electronic devices. Since chemical properties PGMs very similar to each other, hydrometallurgical processes should be employed recover with high purity from either ores or secondary resources. In PGMs, first step is dissolution PGMs. For this purpose, inorganic acid solutions oxidizing ag...

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...
