The current volume of the journal "Nano Hybrids and Composites" presents the last research results in nano-sized functional materials and composites. In the edition are analysed synthesis techniques of some nanomaterials, described results of their properties and microstructure analysis, and explored the perspective of the applications in various engineering areas. The collected articles will be interesting for scientific researchers from nanomaterials and nanotechnologies and also will be helpful to engineers and students in mentioned area of materials science.
