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 …

The moiré superlattice, arising from the interface of mismatched single crystals, intricately
regulates the physical and mechanical properties of materials, giving rise to phenomena …

Structural superlubricity refers to the lubrication state in which the friction between two
crystalline surfaces in incommensurate contact is nearly zero; this has become an important …

The wear-free sliding of layers or flakes of graphene-like 2D materials, important in many
experimental systems, may occur either smoothly or through stick-slip, depending on driving …

The physics of membranes, a classic subject, acquires new momentum from two-
dimensional (2D) materials multilayers. This work reports the surprising results emerged …

Van der Waals heterogeneous interfaces are promising candidates for the scaling up of
structural superlubricity to meet practical applications. Several factors, however, have been …

Sliding ferroelectrics constructed from stacked nonpolar monolayers enable out-of-plane
polarization in two dimensions with exceptional properties, including ultrafast switching …

Recent experiments revealed surprisingly high water-flow rates in narrow carbon
nanotubes, with permeabilities that tend to diverge when the nanotube diameter is …
