Effect of fluid resins on the surface roughness and topography of resin composite restorations analyzed by atomic force microscope
(Elsevier B.V., 2011-04-01)
The aim of the study was to verify the influence of surface sealants on the surface roughness of resin composite restorations before and after mechanical toothbrushing, and evaluate the superficial topography using atomic ...
Vortex state in a mesoscopic flat disk with rough surface
(Elsevier B.V., 2012-09-01)
In this paper we study some superconducting properties of a flat disk by taking into account the roughness of the surface. Also, the sample is surrounded by a thin layer of a metallic material and submitted to and external ...
