Surface energy, surface topography and adhesion [PDF]
International Journal of Adhesion and Adhesives, 2003 Abstract In this paper are discussed some of the fundamental principles which are relevant to an understanding of the influence that interfacial roughness may have on adhesion. The surface energies of the adhesive, substrate and of the interface between them determine the extent of wetting or spreading at equilibrium.

Surface-Energy Engineering of Graphene [PDF]
Langmuir, 2010 Contact angle goniometry is conducted for epitaxial graphene on SiC. Although only a single layer of epitaxial graphene exists on SiC, the contact angle drastically changes from 69 on SiC substrates to 92 with graphene. It is found that there is no thickness dependence of the contact angle from the measurements of single, bi, and multi layer ...

Surface energy of nanoparticles – influence of particle size and structure
Beilstein Journal of Nanotechnology, 2018 The surface energy, particularly for nanoparticles, is one of the most important quantities in understanding the thermodynamics of particles. Therefore, it is astonishing that there is still great uncertainty about its value. The uncertainty increases if

Potential energy surfaces for gas-surface reactions [PDF]
Physical Chemistry Chemical Physics, 2011 A method for constructing the potential energy surface for reactions of a molecule with the surface of cleaved non-conducting crystals is reported. The method uses systematic fragmentation to express the total potential in terms of potential energy surfaces which describe reactions of relatively small molecules in the gas phase.

Easy orientation of diblock copolymers on self-assembled monolayers using UV irradiation
, 2009 A simple method based on UV/ozone treatment is proposed to control the surface energy of dense grafted silane layers for orientating block copolymer mesophases. Our method allows one to tune the surface energy down to a fraction of a mN/m.

New insights into the properties of pubescent surfaces: peach fruit as model [PDF]
, 2011 The surface of peach (Prunus persica ‘Calrico’) is covered by a dense indumentum, which may serve various protective purposes. With the aim of relating structure to function, the chemical composition, morphology, and hydrophobicity of the peach skin was ...
