Abstract Two-dimensional (2D) materials are crystalline materials made of a single or a few
layers of atoms. They have been an active research subject in recent years because of their …

Friction is undoubtedly one of the most common yet intriguing physical phenomena
encountered in our daily lives. It would be impossible to play a stringed instrument or write …

The state of vanishing friction known as superlubricity has important applications for energy
saving and increasing the lifetime of devices. Superlubricity, as detected with atomic force …

Over the recent decades there has been tremendous progress in understanding and
controlling friction between surfaces in relative motion. However the complex nature of the …

A plethora of two-dimensional (2D) materials have been introduced in physics and
engineering in the past two decades. Their robust, membranelike sheets permit (mostly …

Structural superlubricity, which promises an ultralow sliding friction due to the cancellation of
the lateral force between two incommensurate interfaces, is a fundamental phenomenon in …

Static friction induced by moiré superstructures in twisted incommensurate finite layered
material interfaces reveals unique double periodicity and lack of scaling with contact size …

Geometrically imposed force cancellations lead to ultralow friction between rigid
incommensurate crystalline asperities. Elastic deformations may avert this cancellation but …

Tribology, which studies surfaces in contact and relative motion, includes friction, wear, and
lubrication, straddling across different fields: mechanical engineering, materials science …

The unique atomic positions in quasicrystals lead to peculiar self-similarity and fractal-like
structural morphology. Accordingly, many of the material properties are supposed to …
