Adhesion-dependent negative friction coefficient on chemically modified graphite at the nanoscale.
From the early tribological studies of Leonardo da Vinci to Amontons' law, friction has been shown to increase with increasing normal load. This trend continues to hold at the nanoscale, where friction can vary nonlinearly with normal load. Here we present nanoscale friction force microscopy (FFM) experiments for a nanoscale probe tip sliding on a chemically modified graphite surface in an atom...
متن کاملFriction properties of chemically modified starch
Starches of varying chemical structures were esterifi ed with anhydrides, formulated into dry fi lm lubricants with the addition of canola oil, and its friction properties investigated. In the absence of canola, chemically modifi ed starch displayed a very high coeffi cient of friction (COF). Addition of canola resulted in a sharp decrease in COF, which decreased with increasing [canola] until ...
متن کاملChemical Force Microscopy: Exploiting Chemically-Modified Tips To Quantify Adhesion, Friction, and Functional Group Distributions in Molecular Assemblies
Chemical force microscopy (CFM) has been used to measure adhesion and friction forces between probe tips and substrates covalently modified with self-assembled monolayers (SAMs) that terminate in distinct functional groups. Robe tips have been modified with SAMs using a procedure that involves coating commercial Si3N4 cantilevedtip assemblies with a thin layer of polycrystalline Au followed by ...
متن کاملShape Optimization in Contact Problems with Coulomb Friction and a Solution-Dependent Friction Coefficient
The present paper deals with shape optimization in discretized two-dimensional (2D) contact problems with Coulomb friction, where the coefficient of friction is assumed to depend on the unknown solution. Discretization of the continuous state problem leads to a system of finite-dimensional implicit variational inequalities, parametrized by the so-called design variable, that determines the shap...
متن کاملAdhesion and size dependent friction anisotropy in boron nitride nanotubes.
The frictional properties of individual multiwalled boron nitride nanotubes (BN-NTs) synthesized by chemical vapour deposition (CVD) and deposited on a silicon substrate are investigated using an atomic force microscope tip sliding along (longitudinal sliding) and across (transverse sliding) the tube's principal axis. Because of the tube's transverse deformations during the tip sliding, a large...
