Our journal "Nanosystems: Physics, Chemistry, Mathematics" is devoted to fundamental problems of physics, chemistry and mathematics concerning all aspects of nanosystems science. It considers both theoretical and experimental problems of physics and chemistry of nanosystems, including methods of their design and creation, studies of their structure and properties, behavior under external influences, and the possibility of use. We accept papers directly or conceptually related to the key properties of nanosystems. Nanotechnology has required the creation of new methods of mathematical modeling and mathematical physics, as well as the development of existing methods for their extension to the study of new objects, many of which were previously simply absent. The corresponding mathematical problems will be covered in our journal. The scope of the journal includes all areas of nano-sciences. Papers devoted to basic problems of physics, chemistry and mathematics inspired by nanosystems investigations are welcomed. Both theoretical and experimental works concerning the properties and behavior of nanosystems, problems of their creation and application, mathematical methods of nanosystem studies are considered. The journal publishes scientific reviews (up to 30 journal pages), research papers (up to 15 pages) and letters (up to 5 pages). All manuscripts are peer-reviewed. Authors are informed about the referee opinions and the Editorial decisions.
