Synergy of dual-atom catalysts deviated from the scaling relationship for oxygen evolution reaction
Nature Communications, 2023 Dual-atom catalysts, particularly those with heteronuclear active sites, have the potential to outperform the well-established single-atom catalysts for oxygen evolution reaction, but the underlying mechanistic understanding is still lacking.

Comparative Analysis of Subdivided Hex-Derived Networks Using Structural Descriptors
Journal of Chemistry, 2022 A structural descriptor is a numeric quantity, invariant under symmetry, extracted from a molecular graph Γ using tools from mathematics. Hex-derived networks HDN1n and HDN2n being dual of (3,12,12) and (4,8,8) carbon allotrope (nanocones, nanotubes) are

An intermediate level of approximation for computing the dual descriptor
Journal of Molecular Modeling, 2012 At present, there are two levels of approximation to compute the dual descriptor (DD). The first uses the total electronic density of the original system along with the electronic densities of the system with one more electron and one less electron, but this procedure is time consuming and normal termination of computation of total electronic densities
