Inspired by the unique structure and lubrication mechanism of ball bearing, monodisperse, size‐uniform hydrogel spheres are fabricated by Hongyu Zhang, Xiangyang Xu, Wenguo Cui, and co‐workers in article number 2004519 using microfluidic technology, and subsequently modified with pSBMA to form superlubricated hydrogel microspheres using a one‐step bionic grafting approach. The superlubricated hydrogel...
Osteoarthritis, a lubrication dysfunction related disorder in joint, is characterized by articular cartilage degradation and joint capsule inflammation. Enhancing joint lubrication, combined with anti‐inflammatory therapy, is considered as an effective strategy for osteoarthritis treatment. Herein, based on the ball‐bearing‐inspired superlubricity and the mussel‐inspired adhesion, a superlubricated...
As the critical feature sizes of integrated circuits approaching sub‐10 nm, ultrathin gold nanowires (diameter <10 nm) have emerged as one of the most promising candidates for next‐generation interconnects in nanoelectronics. Also due to their ultrasmall dimensions, however, the structures and morphologies of ultrathin gold nanowires are more prone to be damaged during practical services, for example,...
