The α and β peaks were observed on the nonpolar and the stepped surfaces, and the γ peak was observed on the polar surface. The α peak was assigned to adsorption on a surface Zn O pair, and the β peak was assigned to adsorption on an anion vacancy or a step. While adsorbed ...
series of studies of the effect of adsorbate size and polarity on the energetics of adsorption in zeolites.The adsorbate gases used in this study are quadrupolar(N2 and CO2)and nonpolar(Ar,O2,CH4,C2H6,and SF6).The heats of adsorption of both polar and nonpolar gases are either constant or ...
According to the wettability measurements, it was found that loading the ZnO-NPs into the polymer matrix caused not only a change in the relief of the membrane surface but also a redistribution of polar and nonpolar fragments on it. This led to a change in the nature of the surface wettabil...
In this case, during annealing, the hafnium oxide film experiences significant mechanical stress that lowers the phase transition temperature from the high-temperature parent nonpolar cubic Pm3m and tetragonal P42/nmc phases to the polar orthorhombic phase [2,4,5,6]. Despite the progress in ...
The heteronuclear molecule 16O18O is polar and would not have the advantages of a nonpolar molecule, such as intrinsic suppression of electric-field-related systematic effects. Searches for a change in 𝜇 usually involve monitoring the energy difference ℎ𝑓 between two energies with different ...
When metalloporphyrins Tris(perF)P(4-CH2Cl)PPCo (5-(4-(Chloromethyl)phenyl)-10,15,20-tris(perfluorophenyl)porphyrin cobalt(II)) and Tris(perF)P(4-CH2Cl)PPCu were utilized as less polar fluorocarbons [30,31,32] and immobilized on the surface of Si@NH2, the contact angles of ...
