Abstract: The first object of the invention is a method of obtaining a carbide-graphene surface composite with a controlled surface morphology, especially a SiC-graphene composite, characterized in that the SiC substrate, especially with a crystalline or polycrystalline structure, after initial preparation is successively subjected to annealing and then cooling. The second object of the invention is a carbide-graphene composite on a SiC surface, with a crystalline or polycrystalline structure, obtained by the method as defined in the first object of the invention, containing from one to four atomic layers of graphene forming a honeycomb lattice, wherein their diffraction spectrum obtained by the low energy electron diffraction method has a diffraction pattern typical of graphene on the SiC surface, characterized by the fact that it contains a surface covered with terraces or a network of pits, the difference in height of the terraces is from 0.25×10?9 m to 2.

Abstract: A method for preparation of high-quality graphene on the surface (0001) of silicon carbide by superficial graphitisation of the compound in a stream of silicon atoms from an external sublimation source is disclosed.

Abstract: The subjects of the invention are sanitary mats made of natural fibres, the method of obtaining sanitary mats and use of natural fibres to produce sanitary mats. In order to minimise hazards caused by viruses and bacteria, it is very important to consequently implement the cleaning and disinfection programme, which is aimed to decrease the infection hazard by taking the number of microorganisms present in the environment down below a certain secure level. The mat is used to disinfect vehicle wheels and pedestrian shoes.
