This symposium is devoted to the most recent developments in science, technology and social impact of a broad range of nanomaterials, nanodevices and nanosystems. Eight different subtopics will be highlighted and integrated in an effort to draw a current overview of the state-of-the-art in research, recent technology developments and hopes for future prospectives of: Carbon nanostructures and nanocomposites; Nanostructured materials for photonics, electronics and sensors; Theory, modeling, simulation and data science for nanomaterials design; Organic, Inorganic and Hybrid nanoparticles; Nanotechnologies for catalysis and environmental applications; Advanced materials from renewable resources; Nanomaterials for energy storage and conversion; and Bionanomaterials. The goal of the symposium is to present the many cross-disciplinary aspects related to the chemistry, physics, engineering, computational simulation, biology and characterization techniques associated with the fascinating and exciting research field of Nanoscience and Nanotechnology.
