Boundary lubrication ability of lubricants on slideways.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1988 The newly proposed boundary lubrication model in the previous reports is applied to many surfaces (slideways) and the boundary lubricating ability of lubricants is examined thoroughly. The secondary microconstruction of surface asperities and the load carrying pressure distribution of adsorbed lubricant film in contact are taken into consideration in ...

Advanced Functional Materials, EarlyView.For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

Identifying the optimal interfacial parameter correlated with hydrodynamic lubrication
Friction, 2016 The effects of boundary (liquid/solid) slip on hydrodynamics are well recognized. However, it is extremely difficult to quantify in-situ boundary slip in a lubrication contact.

Advanced Healthcare Materials, EarlyView.A water‐activated phospholipid phase‐separation gel is repurposed as a drug‐free surgical barrier for postoperative adhesion prevention. Propylene glycol promotes rapid lamellar gel reinforcement, prolonged local retention, and tissue coverage, while phosphatidylcholine‐mediated immunomodulation suppresses inflammatory and fibrotic responses. This dual‐
