TL;DR: Experimental spectroscopic measurements by scanning tunneling microscopy of highly strained nanobubbles that form when graphene is grown on a platinum surface open the door to both the study of charge carriers in previously inaccessible high magnetic field regimes and deliberate mechanical control over electronic structure in graphene or so-called “strain engineering.”

TL;DR: Scanning tunneling microscopy images show that increasing the number of TB legs "lifts" the azobenzene molecules from the substrate, thereby increasing molecular photomechanical activity by decreasing molecule-surface coupling.

TL;DR: In this paper, the photomechanical switching rates of azobenzene-derived molecules at a gold surface during exposure to UV and visible light were measured using single-molecule-resolved scanning tunneling microscopy.

TL;DR: A new inversion-based dynamical photoswitching mechanism for azobenzene molecules at a surface is proposed that is enabled by the fact that trans-TTB-AB molecules self-assemble into homochiral domains.

TL;DR: Photomechanical switching of molecules at a surface is found to strongly depend on molecule-molecule interactions and molecule-surface orientation, and self-patterned stripes of switching and nonswitching regions were observed having approximately 10 nm pitch.
