Low friction of superslippery and superlubricity: A review

open access: yesFriction, 2022
The issues regarding energy dissipation and component damage caused by the interface friction between a friction pair attract enormous attention to friction reduction. The key-enabling technique to realize friction reduction is the use of lubricants. The

Breaking the symmetry to suppress the Plateau–Rayleigh instability and optimize hydropower utilization

open access: yesNature Communications, 2021
Satellite drops formed on droplet impact hinder applications from inkjet printing to drop energy harvest. Here, authors reveal that patterned-wettability surfaces can break the symmetry of droplet impacts and suppress the Plateau–Rayleigh instability ...
