The hydrophobic properties of sand had attached by fixing soot having superhydrophobic properties of nanoscale layer on the surface of the grains of sand. The resulting sand was examined by scanning electron microscopy to determine the structural and morphological parameters. The resulting composite material is characterized by good water repellent and resistant to external corrosive environments, which allows it to be used in civil and road construction, water-resistant layer for reclamation in hot and arid regions, and in areas where there is a need for bulk materials with hydrophobic properties.展开更多

The influence of the ratio C/O and supply quantity of argon on the formation of graphene layers were researched. It is shown that in the flame of propane and butane on a nickel substrate is observed under these conditions the formation of predominantly 3 - 10 layers of graphene.展开更多
