Strain‐Driven Superlubricity of Graphene/Graphene in Commensurate Contact
Advanced Materials Interfaces, 2023 The occurrence of structural superlubricity (SSL) requires that two sliding surfaces be in incommensurate contact. However, the incommensurate contact between two sliding surfaces is fundamentally an instable state whose maintenance over time is ...

Lubrication Science, EarlyView.ABSTRACT In recent years, doped diamond‐like carbon (DLC) coatings combined with functionalised copolymers have gained attention as a lubrication concept. While silicon‐doped DLC has been widely studied, polymer‐assisted lubrication on other doped DLC systems remains less explored.

Breaking the 2‐nm Barrier in Hard Disk Drives Using Monolayer Amorphous Carbon Overcoats
Advanced Materials, Volume 38, Issue 15, 12 March 2026.The rapid growth of AI has increased demand for large‐scale data storage, making HDDs indispensable in data centers. Increasing areal storage density is crucial, but limited by the traditional carbon overcoats (COC). Monolayer amorphous carbon (MAC) offers a superior alternative.
