Chemical bonding - Atomic Structure, Intermolecular Forces, Covalent Bonds: To understand bond formation, it is necessary to know the general features of the electronic structure of atoms—that is, the arrangement of electrons around the central nucleus.
chemical bondingThe FP-LMTO calculations of dimers (C 59N) 2, (C 59B) 2, (C 59NB), hydroazafullerene C 59NH and hydroborofullerene C 59BH have been made to specify the ground state geometry, parameters of the electronic structure and bonding energies. The boron atom introduced in the ...
The reinvestigation of the Na–Sn compounds yields a number of new results: (i) Na7Sn3is a new thermodynamically-stable phase with a rhombohedral structure andR3mspace group; (ii) orthorhombic Na9Sn4(Cmcm) has relatively slow formation kinetics suggesting why it does not form at room ...
chemical bonding characterThe atomic structure, energetics and chemical bonding state of pristine and Y doped Σ13, (104) grain boundaries in α-Al2O3 were investigated by aberration-corrected Z-contrast scanning transmission electron microscopy combined with first-principles calculations. Combining ...
With density functional theory it was shown that in Y2O3:ZrO2 (YSZ) and SrTiO3 (STO) heterostructures reconstruction of the interfaces between the component units is required to access the most favorable structure (see picture).doi:10.1002/anie.201108068...
