Temperature-controlled, reversible shifting of molecular gear motion in a solid crystal opens new possibilities for material design. Temperature-controlled, reversible shifting of molecular gear ...

(a) Structure of the molecular gears in the clutch stack. (b) Side view of molecular gears showing the two modes of motion observed at lower temperatures (left) and higher temperatures (right).

(Nanowerk News) Gears are an essential component of everyday machines. The ability to shift gears, like in a car, allows for control of the degree or direction of motion generated, making machines ...

Phenylene rings of the clutch-stacked triaryltriazine molecular gears rotate 180°, perpendicular to the molecular plane, interacting with phenylene rings of neighboring molecules in a gear-like ...
