The Saga of “Hypervalent” Molecules

1983
In a previous work, we have outlined the Molecular Orbital-Valence Bond (MOVB) theory of chemical bonding, based on the core(C)-ligand(L) dissection.1 In previous chapters, we have applied this brand of theory to a variety of structural problems with the aim to demonstrate its conceptual and formal advantages over previous and current qualitative ...

Application of local-density functional theory to molecules containing a hypervalent bond

International Journal of Quantum Chemistry, 1991
The molecular and electronic structures of ADPO 1, a model thiapentalene 2, and [Xe2F3]+ have been calculated in the local-density functional (LDF) formalism with polarized double numerical basis sets. The molecules were calculated to have planar C2ν structures in agreement with experiment and in contrast to Hartree–Fock molecular-orbital calculations.

Characteristics of Metal Etching Using Catalyst-Referred Etching Assisted by Anode Oxidation

International Journal of Automation Technology
In a previous study, we developed an abrasive-free polishing method called catalyst-referred etching (CARE). By using water and Pt as an etchant and a catalyst, respectively, atomically smooth surfaces were realized on Si, SiO2, and SiC substrates.

Program-Modulated Kinetics of Perovskite-Film Growth by Molecular "Thruster" for High-Efficiency and Stable Perovskite Solar Cells.

Angewandte Chemie
The rapid reaction between lead iodide (PbI2) and formamidinium iodide (FAI) complicates the fabrication of high-quality formamidinium lead iodide (FAPbI3) films.

Beyond the triple bond: unlocking dinitrogen activation with tailored superbase phosphines.

Dalton Transactions
Activating atmospheric dinitrogen (N2), a molecule with a remarkably strong triple bond, remains a major challenge in chemistry. This theoretical study explores the potential of superbase phosphines, specifically those decorated with imidazolin-2-imine ((
