Gas separation is crucial for industrial production and environmental protection, with metal-organic frameworks (MOFs) offering a promising solution due to their tunable structural properties and chemical compositions. Traditional simulation approaches,
(graph-level) and realizes the information interaction of the pair of ligands. The red and blue nodes represent the graph-level representations of ligandiand ligandj, respectively (x(i)andx(j)), and the yellow nodes present the difference of the two graph-level representations,x(i) −...
(2017) demonstrated that pH significantly changes the free energy of bonding. The interaction of the organic-mineral pairs with changes in pH, when the pH was tested below the pKa (pH = 4), the binding force between carboxylic acid and mica increased by an order of magnitude. This pH...
measured the C=O ∙ ∙ ∙ H-C bonding interaction between a CO tip and the C-H group of an aromatic hydrocarbon before the onset of Pauli repulsion18. Huber et al. studied the interactions between a CO tip with Fe, Cu, and Si adatoms and revealed the bond-forming ...
Constructing well-defined heterostructure interfaces in catalysts is an efficient strategy to break the so-called scaling relationships and to accelerate the reactions involving multiple intermediates. Here a cluster–cluster heterostructure catalyst com
