Permeation of hydrogen across graphdiyne: molecular dynamics vs. quantum simulations and role of membrane motion

This study demonstrates that while quantum effects significantly influence hydrogen permeation through graphdiyne membranes, classical molecular dynamics simulations combined with Feynman-Hibbs corrections can reliably bound these results, provided that the crucial thermal motion of the membrane is included to accurately capture the reduction in permeation barriers.

Complementary Eigen-Zundel Interpretation Reconciles Thermodynamics and Spectroscopy of Excess Protons in Aqueous HF Solutions

Using ab initio molecular dynamics, this study proposes a complementary Eigen-Zundel interpretation that reconciles the apparent contradiction between the distinct thermodynamic behaviors and similar vibrational spectra of excess protons in aqueous HF and HCl solutions by revealing a dynamically shared proton structure and nearly identical proton transfer free-energy profiles.
