Surface wettability effect on aqueous lubrication: Van der Waals and hydration force competition induced adhesive friction

Computer Vision Analysis on Material Characterization Images

“…AFM composed of a tip sensitive to the weak force, scans the sample due to the interaction between the atoms on the surface of the sample and the atoms on the tip of the probe. [10,11,51] Therefore, the position changes of each scanning point of the microcantilever can be measured, and the surface morphology information of the sample with nanometer resolution can be obtained. AFM has three obvious advantages.…”

“…[ 11 ] Second, AFM does not need to pretreat the sample, such as plating conductive film, to prevent irreversible damage. Third, it can work under normal pressure or even in a liquid environment, [ 51 ] which provides opportunities to study biological macromolecules or living biological tissues. However, AFM is sensitive to the probe, resulting in slow imaging speed and small range.…”

Nanohydrodynamic Model and Transport Mechanisms of Tight Oil Confined in Nanopores Considering Liquid–Solid Molecular Interaction Effect

“…Ortiz-Young et al 17 observed the heterogeneous viscosity in the energy dissipated by a tip vibrating in water perpendicular to a surface using atomic force microscopy. Similarly, Li et al 18 evaluated the interfacial viscosity by atomic force microscopy according to the probe dynamic approaching process. Then, to describe heterogeneous viscosity, many empirical models based on the effective viscosity are established by the empirical or regression constants such as interaction coefficient viscosity, but the physical meanings of empirical constants in those models are undefined.…”

Dielectric Properties of Aqueous Electrolyte Solutions Confined in Silica Nanopore: Molecular Simulation vs. Continuum-Based Models

“…Meanwhile, the arrangement of water molecules is constrained by the space and modulated by the potential field of microstructure of the cavity wall, resulting in a colorful order degree and phase structure of confined aqueous system [3][4][5]. The local polarization ability of interfacial water molecules also affects the interactions between water molecules and other charged particles, thus affecting many important physicochemical-processes of interfacial water such as surface hydration [6][7][8], ionic solvation [9][10][11][12], and nanofiltration (NF) mass transfer process [13,14]. During the last decade, the main applications in NF have been in water treatment for drinking water production (including ground and surface water) as well as wastewater treatment.…”
