New Findings in Physics Described from University of Lyon 1 (Wetting of elastic solids on nanopillars)

July 15, 2014

By a News Reporter-Staff News Editor at Physics Week -- Data detailed on Physics have been presented. According to news reporting out of Villeurbanne, France, by VerticalNews editors, research stated, "Solids and liquids are both known to exhibit Cassie-Baxter states, where a drop or a solid nanoparticle is maintained on top of pillars due to wetting forces. We point out that due to elastic strain, solid nanocrystals exhibit a behavior different from that of liquids."

Our news journalists obtained a quote from the research from the University of Lyon 1, "First, the equilibrium Cassie-Baxter state on a single pillar exhibits a spontaneous symmetry breaking due to elastic effects. The second consequence of elasticity is the existence of stable partially impaled states, resulting from a compromise between wetting forces which favor impalement and elastic strain which resists impalement."

According to the news editors, the research concluded: "Based on kinetic Monte Carlo simulations which include elastic strain, we discuss these effects and we propose a global phase diagram for the stability of nanocrystals on nanopillars."
