The spatial distributions of the valence-electron density and the total energy reliefs for water (or methanol) migration on the free surface of graphene are obtained, by using the electron density functional and ab initio pseudopotential methods. Water and methanol molecules are found to migrate along the surface of graphene with an energy relief with barriers and wells. The interaction of water molecules located on the opposite sides of the graphene plane through the regions in the graphene plane with a low electron density is detected. The hovering of molecule over the graphene plane is found to locally change plane’s conductivity. The estimate of energy costs during the propagation of adsorbent molecules over the graphene surface testifies to the graphene hydrophobicity. © A.G. BARYLKA, R.M. BALABAI, 2015. Source

Representative analysis of collected data according to surveying measurements of the earth surface deformations within the mine baffles of Kryvyi Rig iron ore basin is carried out. The relationships between the lowering of the stoping level and change of dimension of basin subsidence and surface collapse across the strike are found. Practical aspects of implementing the methods of diagnosis and monitoring of geoengineering state of rock mass in the lines of shear and collapse zones are considered. © 2012 Taylor & Francis Group, London.
