Computer-modelling techniques are applied to the calculation of defect formation and migration energies in α-Fe 2 O 3 and α-Cr 2 O 3 : both electronic and lattice defects are considered. The results are used to predict Arrhenius energies for cation and anion migration in different composition...
The flotation of graphite particles in aqueous solutions of inorganic electrolytes was shown to depend on both the nature of the cation/anion pair and the ... O Paulson,RJ Pugh - 《Langmuir》 被引量: 95发表: 1996年 Flotation in inorganic electrolytes; the relationship between recover of hydrop...
5d). CR, an anionic azo dye with one central biphenyl group and two symmetric naphtalenic groups are difficult to biodegrade due to their complex aromatic structures; RhB, a cation dye, which can well dissolve in water or organic solvent and has been found to be potentially toxic and ...
Sorption Behavior of p-Nitrophenol on the Interface between Anion-Cation Organobentonite and Water. Describes the simultaneous incorporation of an anionic surfactant, sodium dodecyl sulfate, and a cationic surfactant, dodecyl trimethylammonium bromide, on...

pH 7.5, the rate of deterioration is reduced. Because TC is transformed into an anion or cation and electrostatic repulsion is created in front of the catalyst, the degrading efficiency of the catalyst may be diminished at high or low pH values [44]....
have reported a series of new individual layer nanosheets [12], [13], [14], [15] via exfoliation of the cation-exchangeable layered transition metal oxides or anion-exchangeable layered hydroxides. In addition, our group has recently prepared novel self-stacked Co3O4 nanosheets with superior ...
The magnesioferrite solid solutions that coexist in equilibrium with magnesiowüstite solid solutions have a cation to anion ratio experimentally indistinguishable, in the present study, from 0.750. Curves are presented expressing the change in composition of coexisting magnesioferrite and magnesiowüstite ...
There are such parameters as temperature and pH of the reaction medium, concentration of ions in solution, nature of salt anion and cation of an alkaline agent, presence of uncontrolled or specially introduced impurities in solution, and reagent feed rate that are typical of synthesized by all ...
The basic structural component of such sets is the chemical compound fayalite (2FeO·SiO2), which is ionized in cation Fe2+and anion complex SiO44−. In the course of melting, the components are ionized, and formed are simple cations (e.g., Fe2+, FeO+, and Fe3+), anion complexes ...
