Exploring Molecular Systems

Computational chemistry stands at the crossroads of chemistry and physics, offering a window into the atomic-scale behavior of molecules, their assemblies, and their transformations through reactions, dynamics, and light-matter interactions.

Recent advances in hardware and software have revolutionized our ability to model, simulate, and visualize chemical phenomena, from IR and UV spectra to complex reaction mechanisms. Yet, limited training in specialized tools still hinders broader adoption, highlighting the need for more accessible and interactive learning environments.

Jupyter Notebooks Tools

Jupyter Notebooks, integrated with platforms such as VeloxChem, create an intuitive and engaging space for exploring molecular behavior interactively. Participants gain hands-on experience visualizing electronic transitions, conformational dynamics, and other key processes as they unfold.

An Immersive and Collaborative Experience

• The school includes an online session held the week prior to the in-person event (the link will be sent in due time).
• Combining theory with intensive practice, participants progress step by step under direct expert guidance - learning not only how to use advanced tools, but why they work.
• Beyond traditional lectures, this immersive approach encourages participants to experiment interactively, ask real-time questions, and collaborate with peers facing similar challenges.
• By bringing together researchers from diverse disciplines, the programme sparks interdisciplinary dialogue, strengthens computational skills, and builds a community ready to advance molecular science.

These sessions are either open for abstract submissions or closed, meaning that session owners are responsible for selecting and confirming speakers for their session (closed sessions are still open for all registered Congress participants to attend).

Workshops and meetings will also take place and are, in most cases, closed - both in terms of selecting active participants and general attendance. However, this may vary depending on the purpose of the session. The “owner” of the workshop or meeting is responsible for coordinating with the Congress organisers to clarify expected participant numbers and agree on any specific requirements, ensuring that suitable facilities and arrangements can be made in due time.

For full theme descriptions and a list of sub-themes, please read the full call for session proposals. Session proposals that do not directly match a listed theme may be submitted under the category "Other", provided their relevance is clearly explained.

We especially encourage sessions that include the participation of Indigenous peoples, youth, and local communities, and that apply transdisciplinary approaches to research and dialogue. Sessions can include oral and/or poster presentations, panel discussions, and roundtable dialogues. The official language of the Congress is English.

In summary

• ‍Abstracts are required for oral presentations, poster presentations, panel discussions, and roundtable discussions that are open for submissions.
• Closed sessions do not require abstracts, but session owners must submit a list of speakers by the deadline of 15 January 2026.
• Workshops and meetings will also take place but do not require abstract submissions.

All sessions will be held exclusively onsite at the arena við Tjarnir, at Atlagøta, Hoyvík, Faroe Islands.

The Arctic is predominantly covered by oceans. The Arctic seas are of immense importance for the people in the Arctic and in articular Indigenous Peoples and their communities who depend on the health of the sea for their livelihoods and way of life. Ongoing warming and the reduction of sea ice call upon us to step up monitoring developments and to identify the drivers of change thereby enhancing predictability and effective management of the changing marine environment.

The Kingdom of Denmark's Chairship of the Arctic Council is organizing the international Ocean Connectivity Conference dedicated to Sub Arctic and High Arctic connectivity. The conference will emphasize implications for biodiversity and migrating species, climate change impacts, pollutant transport and the movement of species between regions, including movement of invasive species to the High Arctic. It will also highlight the significance of sustainable management practices for the Arctic marine environment, reinforcing the importance of responsible Arctic marine monitoring and governance. The aim is to facilitate knowledge exchange initiatives and connect research findings and Indigenous Knowledge with a view to establishing best practices. The Ocean conference will be aligned with the Ocean Decade agenda.
