A microscopic analysis of the differences in Gibbs free energy between covalent, ionic, and metallic forms of ANB8-N compounds is described. The analysis explains the success of the spectroscopic theory of chemical bonds in predicting the covalent-ionic transition at zero pressure as a function of...

Calculations of the mutual neutralisation of N + by O and O + by O for energies between 0.8 and 2000 eV are carried out using the multi-channel Landau-Zener model and an asymptotic method to obtain the ionic-covalent coupling matrix elements. The mutual neutralisation cross sections obtained ...

N-dopedβ-ketoenamine based COFs (TP-BD-COF(0N),TP-PD-COF(1N),TP-PMD-COF(2N)) were successfully constructed and fully characterized.TP-BD-COFexhibited highest catalytic efficiency (99%) for CO2cycloaddition reaction thanTP-PD-COF(87%) andTP-PMD-COF(85%).The order of catalytic efficiency...
The O–H covalent bond length of MSA is considerably augmented to 1.432 Å, and a proton transfer takes place from MSA to H2O. This results in the development of an ionic pair, CH3SO3−⋯H3O+. Second isomer 2 of MSA⋅(H2O)4, shown in Fig. 2f, can be viewed as modification ...
2a, b), resulting in interfaces that account for nearly 50% of the total buried surface area, with approximately 1421 Å2 on each side, mainly through hydrogen bonding and ionic interactions between the LinkerDH-KR/ψKR and LD-AT domains of opposite chains (Supplementary Fig. 7). This ...
