Smaller critical size and enhanced strength by nano-laminated structure in nickel

, 2015
Because of a shift in the dominant deformation mechanisms, the strength/hardness of metals increases with decreasing grain size down to a critical value, then decreases with further grain refinement.

LAMINATIONS WITH TRANSVERSE STRUCTURE

Topology, 1999
Associated to a lamination of a 3-manifold by surfaces is a certain tree-like object acted upon by the fundamental group of the manifold. Geometric structures on the tree preserved by the action of the fundamental group correspond to transverse structures on the lamination and impose conditions on the lamination and the ambient manifold.

Fluid–Structure Interaction Mechanisms of Layered Thickness Effects on Lubrication Performance and Energy Dissipation in Water-Lubricated Bearings

Lubricants
Traditional single-layer water-lubricated rubber or plastic bearings suffer from water film rupture, excessive frictional losses, and insufficient load-carrying capacity, which limit performance and service life in marine propulsion and ocean engineering.
