ProbeParticle workflow for water and CO adsorption on Calcite

Reusable workflow to generate ProbeParticle images, as used in::

Heggemann, Jonas, Yashasvi S. Ranawat, Ondřej Krejčí, Adam S. Foster, and Philipp Rahe. "Differences in Molecular Adsorption Emanating from the (2× 1) Reconstruction of Calcite (104)." The Journal of Physical Chemistry Letters 14, no. 7 (2023): 1983-1989.

Install

Clone the required git repositories::

git clone --recurse-submodules https://github.com/SINGROUP/ProbeParticle_workflow.git

Install python dependencies, using pipenv::

pipenv sync

Enter the virtual environment using::

pipenv shell

Usage

The workflow requires POSCAR, LOCPOT and CHGCAR files from VASP simulation of the system. These files should be added to the data folder with the same prefix, as shown by "example" files. The workflow.ipynb has the cells to add the workflow to an ASE database.

NOTE: Add a vacuum of atleast 20Å over the system for better visualisation.

Runner is used to run the workflow. There are two ways to run the workflow once added to the database::

• with a slurm workflow manager
• with terminal.

Use the correct runner definition from the workflow.ipynb for your environment. Once added to the workflow, runner can be started by::

# for slurm runner
python run.py

# for terminal runner
python run_terminal.py

After the run finishes, the database is updated with the relevant data. This data can be retrieved by running the "data retrieval" cell in workflow.ipynb. This adds the relevant cells in the Images folder.

The Images.ipynb (in the Images folder) can be used to visualise the images generated from the ProbeParticle workflow.
