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 graphene

SYMMETRY ENERGY IN NUCLEAR SURFACE [PDF]
International Journal of Modern Physics E, 2009 Interplay between the dependence of symmetry energy on density and the variation of nucleonic densities across nuclear surface is discussed. That interplay gives rise to the mass dependence of the symmetry coefficient in an energy formula. Charge symmetry of the nuclear interactions allows to introduce isoscalar and isovector densities that are ...

Size effect of the surface energy density of nanoparticles [PDF]
, 2015 The surface energy density of nanoparticles exhibits an obviously size-dependent behavior. However, how the surface energy density changes with the diameter of nanoparticles is still ambiguous. Based on a recently developed continuum theory considering

Variability of Energy Dissipation and Shear Rate with Geometry in Unbaffled Surface Aerator [PDF]
, 2009 mixing in surface aerators. At constant dynamic variables (rotational speed), both and γ are greatly affected by the geometric parameters (impeller diameter, cross-sectional area of the tank, liquid height, rotor blade length and immersion height). By
