Overview
First General Meeting of the COST Action CA21101 – COSY: Confined Molecular Systems: From a New Generation of Materials to the Stars.
COST (European Cooperation in Science and Technology) is a funding organisation for research and innovation networks. Our Actions help connect research initiatives across Europe and beyond and enable researchers and innovators to grow their ideas in any science and technology field by sharing them with their peers. COST Actions are bottom-up networks with a duration of four years that boost research, innovation and careers.
This COST Action aims to provide a computationally and experimentally sound foundation for the fundamental understanding and control of confined molecular systems. The resulting outcome will be translated into useful knowledge forming the basis for applications. These range from creating a new generation of materials including bio-materials, with immediate transfer to industry, to disclosing the chemistry occurring in space.
“COSY” is the acronym for “Confined Molecular Systems: from the new generation of materials to the stars”, a COST Action (acronym for European Cooperation in Science and Technology). It is basically a platform for cooperation between research groups in Europe that have nationally funded projects in confined molecular systems. The COST Action “COSY” aims to provide computational and experimental building blocks for a fundamental understanding of confined molecular systems in order to be able to control them. The platform already brings together more than 180 groups from around 35 member countries of the European Union. It is structured in five strongly correlated working groups whose objectives range from a first-principles description of the interaction between a molecule and its environment, including the interstellar medium, to the synthesis of new materials with theranostic applications, energy conversion, and photocatalysis.

We cordially invite members of the COST Action CA21101 (“COSY”), as well as all interested parties, to Cádiz, for the First General Meeting of our COST Action. It will be dedicated to a better understanding and recognition of issues relevant to the experimental and theoretical characterization of confined molecular systems, from those relevant in new materials research, to those playing a key role in astrochemistry. It is an opportunity for active networking between Action members with complementary and highly diverse expertise in confined molecular systems. This first COSY General Meeting is intended to be a forum for detailed discussions. It will thus provide an opportunity for the members of the Action’s five Working Groups (WGs) to undertake activities that will address the goals of the 1st Grant Period of the COST Action. For this purpose, the meeting will host dedicated sessions for the five WGs. In addition to invited talks of 25 minutes by COSY members from all WGs, the participants will be also invited to present hot topic posters preceded by 2-minutes flash presentations which will be held after the first scientific session.
The meeting will be organized by the Universidad de Cádiz (Cádiz, Spain). It will start on Wednesday, the 1st of March in the morning and end on Friday, the 3rd of March before lunch.
The meeting will serve as a platform to connect the five Working Groups (WGs) of COSY: (WG1: red, WG2: brown; WG3: violet; WG4 blue; WG5: green).

Working Groups
The meeting will serve as a vehicle to conect the five Working Groups (Wgs) of COSY:
- WG1 – Intermolecular Interactions – Ab initio-Generated Force Fields and Machine Learning.
- WG2 – Molecular Motion in Confined Systems.
- WG3 – Confined Metal and Metal-Oxide Nanoparticles and Clusters Down to the Subnanometer Scale.
- WG4 – Helium Nanodroplets in Science and Engineering.
- WG5 – Confined Systems in Astrochemistry: Gas- and Condensed-Phase Spectroscopy and Reactivity.
