PTFE slabs with no intervening lubricant

These simulations reveal the molecular-scale wear protection provided by a lubricating layer between polymer slabs. The slabs are transparent to highlight five molecular chains (green and black) at the interface. In the absence of lubricant the chains quickly bunch up and degrade.

PTFE slabs with multiple monolayers of lubricant

These simulations reveal the molecular-scale wear protection provided by a lubricating layer between polymer slabs. The slabs are transparent to highlight five molecular chains (green and black) at the interface. When a few monolayers of C2F6 lubricant are present (multicolored section in video) the polymer chains remain largely in place and intact.

Dip And Pull

Scanning electron microscopy video shows what happens when a silver-coated atomic force microscopy tip is dipped into a drop of liquid gallium at room temperature: Gallium readily adheres to the silver-coated tip, and as the tip is retracted, a nanowire of Ag2Ga alloy forms and eventually detaches from the gallium drop (J. Appl. Phys. 2005, 98, 073510-1).

Forces associated with a femtosecond laser pulse (white cone) compress the interlayer spacings in a graphite crystal, momentarily transforming the material to diamond (lattice with red spheres). The forces then expand the spacings, thereby separating the graphene sheets in graphite. (The degree of expansion is exaggerated in this artistic video rendering.)
