Articles collected in this issue present to readers the results of applied nano research. The various nanoparticles were studied and analysed for applications in microelectronics, sensors, biosensors, and devices for energy storage and conversion. The properties of structural nanocomposites based on graphene and nano cellulose were considered in some articles. There was also an analysis of the use of nanomaterials in archaeological object restoration. This volume will be helpful to specialists in nanomaterials and nanotechnologies applications.
