and then its surface charge density is estimated from the above ζ potential based on Gouy-Chapmann equation.The ζ potential of the suspended particles in the oily sewage from oilfields is measured.The experimental and the calculation results show that there is negative charge in the membrane ...
whereVandρare the droplet’s volume and density, respectively, andgis the gravitational acceleration. Usually, the contact line is assumed to be circular for highly repellent surfaces, but it can be elongated along the sliding direction if there are strong pinning sites, with lengthd∥along the...

Surface defect refers to intentional modifications made on the surface of photocatalysts to enhance their photocatalytic activity by narrowing the band gap, tuning the electronic structure, and serving as charge carrier traps to inhibit electron-hole recombination. ...
Thus, the presence of regolith, the relatively low density, the VNIR spectra and the elevated S at the Venera and Vega sites, where measured, are consistent with a weathered basaltic clastic rock that contains hematite and sulfate. 3.2Near Infrared Imaging ...
(E); comparison of onset overpotential and overpotential for FeNi-LDH/Ti3C2-MXene, FeNi-LDH + Ti3C2-MXene, FeNi-LDH/rGO, FeNi-LDH, Ni(OH)2, Ti3C2 MXene, and RuO2 catalysts (F); Tafel plots of these catalysts (G); and differential charge density in FeNi-LDH/Ti3C2-MXene hybrid ...
Light scattering by small particles has a long and interesting history in physics. Nonetheless, it continues to surprise with new insights and applications. This includes new discoveries, such as novel plasmonic effects, as well as exciting theoretical a
The doping/temperature evolution of the density of localized charge, as extracted from the resistivity, is indicated by blue shading. Solid black and dashed grey lines are isodensity lines. In the OD-FL regime, all carriers contribute to electronic transport. Both, the pseudogap Fermi liquid (...
(Bi2Te3)ncompounds, including axion insulators, Weyl semimetals, 3D Chern insulators, and 3D QSH insulators. Their distinctive surface AHC features are comprehensively studied. In addition to the model study, we then construct atomistic Hamiltonians from density-functional theory (DFT) with close ...
The charge-density distribution in the (010) plane is suppressed by the PEA+ cation with a weak hybridization of atomic orbitals. On the other hand, the dispersion of charge distribution in the VBM and CBM of the (001) plane is more intense than that of (010) plane, implying that ...
