[GAPG-1] Dissemination:To further develop the dissemination strategy of COST Action results and acquired knowledge described in the communication plan. During the 2nd Grant Period, specific goals are the opening of a webinar series, the celebration of an event dedicated to improve communication skills of young research investigators when presenting achievements of the COST Action, and the creation of separate podcasts for the five working groups to highlight the goals and early achievements of the COSY COST Action.

[GAPG-3] WG1/WG1-5: Development and testing of Symmetry-Adapted Perturbation Theory (SAPT) and hybrid methods which are applicable to systems featuring strong multi-reference character (e.g., metal atoms interacting with hydrocarbons) and generalize SAPT to degenerate states, extending coupled second-order Möller-Plesset perturbation theory to multiconfigurational wave-functions. To explore the use of automatic generation of potential energy surfaces for gas-phase collisions with immediate applications in astrochemistry and atmospheric chemistry. To work out a joint multi-author publication dedicated to the interactions of metal atoms (Al, Ca, Mg) with hydrocarbons.

[GAPG-5] WG3/WG1-5: Design, synthesis, and characterization of nanoclusters with different properties and functions, with an emphasis on nanotomography; understanding the effects of quantum confinement on supported substrates, control and manipulation at the nanoscale; (in cooperation with WG1 and WG2) developing new computational tools to address current challenges in achieving a more fundamental understanding of the structure and behavior of subnanometric (transition) metal and metal-oxide clusters, focusing on clustersurface interactions and challenges such as the design of viable photo-catalysts for water purification. Discussion of systems/problems which might connect WG3 and WG5. Metal/metal oxide catalysis which might be relevant in the field of astrochemistry will be also addressed.

[GAPG-6] WG4/WG1-5: The synthesis of tailored aggregates will be further advanced by using other atomic and molecular clusters as nanoscale test tubes, in addition to neutral and charged helium nanodroplets. The ultrafast dynamics of molecules confined in helium nanodroplets will be investigated both experimentally and theoretically. The topic of helium-droplet-mediated surface deposition will be specifically addressed. The possibility of forming task-force groups on highly specialized topics will also be discussed. A Themed Collection of publications entitled “Spectroscopy, imaging, and dynamics of molecules confined in helium nanodroplets” will be launched.

[GAPG-7] WG5/WG1-4: The selection of molecular systems of astrochemical relevance in the gas and condensed phases, including their interphases; the investigation of reaction dynamics of the systems considered, supported by accurate ab initio calculations of the interaction potentials involved; spectroscopic/physicalchemical characterization of the confined systems selected. Creation of a positioning paper involving all WG5 members. It will be aimed at providing a complete review and future perspectives on the chemical (e.g., prebiotic) reactivity occurring in the interstellar medium. Emphasis will be given on the need of integrating the different skills and competences in order to obtain a complete view.
