Distinct AI2MD Trajectories
This comprehensive dataset includes a wide range of electrochemical interfaces, covering 2D materials, zinc-blend-type semiconductors, oxides, and metals. The inclusion of MLMD trajectories for systems like Pt(111), SnO2(110), GaP(110), r-TiO2(110), and CoO(100)/(111) extends the accessible simulation timescales to nanoseconds, maintaining ab initio accuracy. This broad scope facilitates cross-study comparisons and meta-analyses, driving new insights into solid-liquid interactions.
Automated Proton Transfer Pathway Detection
Understanding proton transfer at interfaces is critical but challenging. ElectroFace employs advanced algorithms to automatically identify and visualize these complex events, as exemplified by the SnO2(110)-water interface.
Case Study: Automated Proton Transfer Analysis
Problem: Traditional manual visualization of proton transfer pathways from MD trajectories is tedious and prone to overlooking subtle Grotthuss mechanisms, hindering accurate reaction free energy profile construction.
Solution: A modified proton tracking algorithm within the ai2-kit package automatically detects proton transfer events, tracking pseudo-atoms to represent transferred protons and visualize their pathways, such as the Grotthuss mechanism involving two solvent water molecules at SnO2(110).
Impact: This automation significantly streamlines the analysis of complex interfacial reactions, providing clearer mechanistic insights and aiding in the development of more accurate models for electrochemistry and materials science. Users can validate pathways directly through visualization tools.
