The sixth International Conference "Dynamics of Systems on the Nanoscale" (DySoN) and the tenth International Symposium "Atomic Cluster Collisions" (ISACC) will be organized jointly under the title "DySoN-ISACC 2021 Conference".

The DySoN-ISACC 2021 Conference will take place on October 18-22, 2021 in Santa Margherita Ligure, Italy. It is co-organized by the University of Ferrara (Ferrara, Italy), University of Kent (Canterbury, United Kingdom) and MBN Research Center (Frankfurt am Main, Germany).

A series of International Symposia "Atomic Cluster Collisions: structure and dynamics from the nuclear to the biological scale" started in 2003, and nine ISACC conferences have been held so far. The ISACC series promotes the growth and exchange of scientific information on the structure, properties and dynamics of complex nuclear, atomic, molecular, cluster, nanoscopic and biological systems studied primarily by means of photonic, electronic and atomic collisions. Most of the ISACC conferences were satellites of the International Conferences on Photonic Electronic and Atomic Collisions (ICPEAC). In light of the Covid-19 pandemic the XXXIII ICPEAC Conference has been postponed to 2023. Despite this, the ISACC International Advisory Committee decided to organize the Tenth ISACC Symposium in 2021 as a joint meeting with the DySoN 2021 conference.

The "Dynamics of Systems on the Nanoscale" conference has been built upon the ISACC series reflecting a need for an interdisciplinary conference covering a broader range of topics than just atomic cluster collisions, related to the Dynamics of Systems on the Nanoscale. The DySoN conference series was launched in 2010 and five 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 origin, 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 in 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.

The joint DySoN-ISACC 2021 Conference will cover experimental, theoretical and applied aspects of all the aforementioned topics. Particular attention will be devoted to dynamical phenomena and many-body effects taking place in various MBN systems on the nanoscale, which 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, irradiation-induced biodamage, channeling phenomena, construction of novel light sources, and many more. The utilization of advanced computational techniques and high-performance computing for studying the aforementioned phenomena and effects will also be discussed. Links of the DySoN and ISACC topics to novel and emerging technologies will be an important focus of the DySoN-ISACC 2021 Conference.

Finally, DySoN-ISACC 2021 will provide a platform to host discussions about current research, technological challenges and related initiatives within the Topical Areas of DySoN and ISACC Conference Series.
