The Seventh International Conference “Dynamics of Systems on the Nanoscale” (DySoN 2023) will take place on April 24-26, 2023, in Villa Lanna, Prague, Czech Republic. The DySoN Conference will be followed by the 2nd Annual Conference of the COST Action CA20129 "Multiscale Irradiation and Chemistry Driven Processes and Related Technologies" (MultIChem), which will be held on April 26-28 at the same venue.

DySoN is an interdisciplinary conference series covering a broad range of topics related to the Dynamics of Systems on the Nanoscale. The DySoN conference series was launched in 2010, and six DySoN conferences have been held so far. The DySoN conferences promote the growth and exchange of interdisciplinary scientific information on the structure formation and dynamics of animate and inanimate matter on the nanometer scale. There are many examples of complex many-body systems of micro- and nanometer scale size exhibiting unique features, properties and functions. These systems may have very different nature and origins, e.g. atomic and molecular clusters, nanostructures, ensembles of nanoparticles, nanomaterials, biomolecules, biomolecular and mesoscopic systems. A detailed understanding of the structure and dynamics of these systems on the nanoscale is a difficult and fundamental task, the solution of which is necessary for nano- and biotechnologies, materials science and medicine.

Although mesoscopic, nano- and biomolecular systems differ in their nature and origin, a number of fundamental problems are common to all of them: What are the underlying principles of self-organization and self-assembly of matter at the micro- and nanoscale? Are these principles classical or quantum? How does function emerge at the nano- and mesoscale in systems of different origin? What criteria govern the stability of these systems? How do their properties change as a function of size and composition? How are their properties altered by their environment? Seeking answers to these questions is at the core of a new interdisciplinary field that lies at the intersection of physics, chemistry and biology, a field now entitled Meso-Bio-Nano (MBN) Science.

Experimental, theoretical, computational and applied aspects of the aforementioned problems will be discussed at the DySoN 2023 Conference. Particular attention will be devoted to dynamical phenomena and many-body effects taking place in various MBN systems on the nanoscale. They include problems of structure formation; fusion and fission; collision and fragmentation; surfaces and interfaces; collective electron excitations; reactivity; nanoscale phase and morphological transitions; irradiation-driven transformations of complex molecular systems and biodamage, channeling phenomena, and many more. Links of the DySoN topics to novel and emerging technologies will be an important focus of the conference.

Finally, DySoN 2023 will provide a platform to host discussions about current research, technological challenges and related initiatives within the Topical Areas of the DySoN conference series. 

The following topics will be addressed within the DySoN 2023 Conference:

  • Structure and dynamics of molecules, clusters and nanoparticles
  • Cluster and biomolecular ensembles, composite systems
  • Clustering, self-organization, phase and morphological transitions on the nanoscale
  • Nanostructured materials, surfaces and interfaces
  • Reactivity and nanocatalysis
  • Electron and spin transport in molecular systems
  • Collision and radiation processes, fusion, fission, fragmentation
  • Radiation-induced chemistry
  • Irradiation-driven transformations, damage and fabrication of MesoBioNano systems
  • Propagation of particles through media
  • Biomedical and technological applications of radiation
  • Related technologies: novel light sources, controlled nanofabrication, functionalized materials, etc.
