From the simulation, it can be found that the inhibition efficiency afforded by DEAMB may be due to the its electron rich N atoms, imidazole and phenyl group, and the possible coordination points are unshared electron pair of heteroatoms and p-electrons of imidazole and phenyl group.
Thus, the bond angles and bond length modifications of the C atoms and their attached passivation agents can be explained using valence shell electron pair repulsion (VSEPR) theory [30].

Nine studies consider such topics as the reactivity of unstable chemicals in the presence of transition metals, the comparative statistics of Cooper's electron pairs in low-temperature superconductors and in coupled holes pairs in high-temperature ceramics, vitamin E as an example of applying rare earth triflates as efficient catalysts in the fine chemicals industry, and the fractal physical chemistry of polymer solutions.
The proper voltage (about 2000 V) is obtained when the magnitude of the number of electron pairs is proportional to the x-ray energy of the incoming photon (just like a Si(Li) detector).
It is very likely that hydrazine binds between the copper centers of the binuclear complex through the lone electron pairs of the hydrazine nitrogen atoms.
One of the characteristics of metallic hexagonal crystals is diamagnetic behavior, and the thought occurred to me that if diamagnetic effects were enhanced several orders of magnitude by means of such electron pairs channeling through a hexagonal matrix, then the diamagnetic field generated could successfully grapple with even our weak geomagnetic field to effect a magnetic repulsion of a physical mass encountering and entering Earth's environment.
The quantum state of the first qubit, which is defined by the number of superconducting electron pairs (also known as Cooper pairs) contained in it, was first transferred to a microwave photon of a resonator using very precisely controlled microwave pulses.
Their inhibiting action can be deduced based on the number of available electron pairs, pi-orbital behaviour of available electrons and the electron density around the heteroatom [11-16].
The year 2016 then, marks the 100th anniversary of Lewis's concept of the covalent bond model and electron pairs. Only 100 years ago, chemists and physicists were still trying to understand the basic building blocks of molecules.
