The nanotribology of an alkanethiol self-assembled monolayer (SAM) under tilt contact with a scanning probe tip is studied using molecular dynamics (MD) simulations. The tilt contact is described in terms of the tilt angle and the magnitude of the specimen–tip separation. The effects of tilt angle and magnitude of the specimen–tip separation on the normal force, friction force, friction coefficient,...
The elasticity and nanomechanical response of Aspergillus niger spores determined using atomic force microscopy (AFM) and nanoindentation are discussed. The force-displacement curve of the spore surfaces shows that the average surface roughness of spores was approximately 33nm and that the adhesion force ranged from 9 to 28nN. The Young's modulus of the A. niger spores ranged from 0.1 to 21.4GPa and...
The temperature-dependent mechanical properties of polyethylene terephthalate (PET) polymers are investigated using force–distance curves, adhesion force, and atomic force microscope (AFM) nanolithography combined the heating techniques. The results show that the width of grooves on the polymers at 20–60°C were in the range of 14–363nm. The wear depth of the polymers increased with increasing heating...
