it can also be noted that the nh 3 molecule undergoes self dissociation when dissolved in water. the molecular autoionization of the ammonia molecule results in the formation of its conjugate base (nh 2 – ) and its conjugate acid (nh 4 + ). the structure of the ammonium cation is ...

Further, the transmission electron microscopy (TEM) reveals that the crystal is composed of multi-lamellar nano-tubes with diameters less than 100 nm. The molecular structure of the complex was compared with that of its isomer complex 2.中国化学(英文版)...
The density of states (DOS) spectrum, lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) of stanene and stanane nanosheet were estimated using Gauss Sum 3.0 package [35]. We have selected the super cell geometry of 4 × 4 × 1 with a vacuum ...
(CH2)nNH3]MX2X’2, composed of different halogen ions, was conducted by Abdel-Aal et al.53,54,55. The physical and chemical properties of the organic–inorganic hybrid perovskite compounds depend on the characteristics of the organic cations and the coordination geometry of the inorganic anions...

Mulliken charge analysis shows that lead (Pb) atom acquires a maximum positive charge and all iodine atoms get a negative charge. In addition to this, all the hydrogen atoms donate their charge to iodine atoms. Therefore, electron transfer from lead (Pb) and hydrogen atoms to the iodine ...
Structures and stabilities of small silicon clusters: Ab initio molecular-orbital calculations of Si[sub 7]–Si[sub 11]. Ab initio all-electron molecular-orbital calculations have been carried out to study the structure and relative stability of small silicon clusters (Si[sub... Zhu,Xiaolei,Zeng...
reduce the dislocation density and electron trapping. The techniques to grow AlN can be categorized into physical methods, including sublimation [8], [9], reactive sputtering [10], pulsed laser deposition (PLD) and molecular beam epitaxy (MBE), and chemical methods, including chemical vapor ...
