Wetting and friction on superoleophobic surfaces
This article describes the physics of superoleophobic surfaces, combining a recently developed free-energy approach and finite element modeling. We start by investigating the peculiar wetting behavior of such surfaces, originating in their “re-entrant” geometry, and discussing a specific mechanism for the “filling transition”, leading to the loss of superoleophobicity. We then focus on their fr...
متن کاملMicroscopic Friction Studies on Metal Surfaces
Atomically flat and clean metal surfaces exhibit a regime of ultra-low friction at low normal loads. Atomic force microscopy, performed in ultra-high vacuum on Cu(100) and Au(111) surfaces, reveals a clear stick-slip modulation in the lateral force but almost zero dissipation. Significant friction is observed only for higher loads (*4– 6 nN above the pull-off force) together with the onset of w...

متن کاملOn friction behavior of rubber on concrete surfaces
T h e frict,ion behavior of rubber materials on various contact surfaces is strongly affected by the contact pressure and the relative sliding velocity. Based on a great number of experiment,^ of rubber block moving on concrete surfaces. a friction law is present,ed in this paper. It is characterized b~ a dependence on contact pressure and sliding velocity. The identification of the required pa...
متن کاملOn Local Coefficients of Simplicial Coalgebras
This paper generalizes the notion of local coefficients and fundamental groups of spaces to simplicial coalgebras. We define a Hopf algebra π1(C) from a simplicial coalgebra C as a generalization of a fundamental group, and show that a module overπ1(C) corresponds to a local coefficient of C. As a consequence, the Hoschild cohomology of a Hopf algebraH with a coefficient M coincides with the co...
