Digital Adsorption Data Space: An IUPAC Task Force Symposium
Channel: International Adsorption Society
Date: 2023-06-13

This symposium describes the "Adsorption Information Format" file, which is a standardized expression of equilibrium adsorption isotherm measurements.

New advanced adsorbents are a crucial driver for the development of energy and environmental applications. There is tremendous potential provided by machine learning and data mining techniques to identify an adsorbent for a particular application. However, the current scientific reporting of adsorption isotherms in graphs and figures is not adequate to reproduce original experimentally measured data.

In our interactive workshop, advanced data formats and their implementation in publications and databases are illustrated. Specifically, we present a new standard format for isotherms, the Adsorption Information File (AIF), which is built on the self-defining text archive and retrieval (STAR) format that is similarly used for the ubiquitous Crystallographic Information File. The AIF is a flexible, general and easily extended free-format archive file that is readily human and machine readable - simple to edit using a basic text editor or to parse for database curation.

Applications of adsorption data archiving, visualization and interaction with the NIST isotherm database for a wide range of porous materials (activated carbons, metal-organic frameworks, high pressure data etc.) will be discussed including experimental and simulation data (e.g. RASPA data).

Archiving adsorption data in an advanced, open, and consistent format following FAIR guidelines will facilitate the electronic transmission of adsorption data between laboratories, journals and larger databases and increase opportunities for open science in the field of adsorption by porous materials, nanomaterials and catalysts in future.
