Summary of the points zero charge (PZC) and isoelectric (IEP) various materials published in recent literature older results overlooked previous compilations. The roles experimental conditions, especially temperature, nature concentration supporting electrolyte, type apparatus are emphasized. newest compared with reported reviews. Most studies were carried out whose pH dependent surface charging is already well-documented, consistent literature. Isoelectric Gd(OH)3, Sm(OH)3, TeO2 have been...

Electrophoretic mobility of titania nanoparticles in ethane-1,2-diol and propane-1,2-diol the presence SDS sodium octadecylsulfate was measured. Several dispersions were acidified with HCl or alkalized NaOH. Addition acid resulted positive addition base negative zeta potential. Anionic surfactants have moderate effect on They enhanced potential, but their became significant at surfactant concentrations as high 1 g/L. Sodium more efficient than shifting potential to values.

Many empirical formulas have been proposed in the literature to estimate pristine points of zero charge oxides from ionic radii and coordination numbers or electronegativities, good correlations between experimental calculated values were obtained. The significance such studies is limited unless accurate reliable point (PPZC) data are used. Comparison various compilations PPZC shows that more attention should be paid proper choice an unique among many reported for same oxide literature. Only...

The reduction of absolute values negative ζ potentials (basic branch) anatase with the concentration 1−1 salts (alkali halides, nitrates, and perchlorates) is much more pronounced than that positive (acidic branch). extent this effect increases in series Cs < K Na Li for a given anion CH3COO Cl NO3 ClO4 Br I cation. For sufficiently high concentrations most lithium sodium salts, e.g., 0.53 mol dm-3 NaI, there no isoelectric point (iep) are over entire available pH range. potassium cesium an...

Dispersions of solid particles in glycols and their mixtures water have been proposed as promising heat transfer fluids, the zeta potentials such systems are often reported. We challenge a popular approach which high absolute value potential implies excellent stability systems. Nanoparticles alumina were dispersed 50–50 ethylene glycol-water mixture, particle size studied function concentration various solutes. Addition HCl CTMABr induced positive potentials. A maximum about 120 mV was...

A new ranking of universities (The Magnificent 7, TM7) is based on the ranks top seven scientists from a given university in scientists. This idea was tested using recent rankings total number independent citations, h-index, Schreiber’s hm index, and composite index by Ioannidis et al. The TM7 mentioned four criteria are highly correlated. compared with their other popular like Shanghai Times Higher Education ranking. can be used any updated when updated.
