The interaction of mother and infant is a fundamental basis for the development infant. It can also determine success baby in future. About 4 out 10 infants experience problems interacting with their parents. NBO system was created to sensitize parents on infant’s competencies help them understand behavior, promote positive interactions between new This study aimed evaluate effectiveness improv...

Through N-alkylation of 1,4-diazabicyclo [2.2.2] octane with 1-bromooctane a new ionic liquid, namely 1?octyl?1,4?diazabicyclo octan?1?ium Bromide [C8DABCO+][Br?] has been synthesized and characterized by FT-IR, FT-Raman 1H 13C-NMR spectroscopies. Three C-H•••Br bonds were predicted natural bond orbital (NBO), atoms in molecules (AIM) calculations orders but monodentate coordination between cat...

ABSTRACT. A novel distorted square-planar palladium(II) complex of the type [Pd(Hdz)(PPh3)Cl], where (Hdz = dithizone mono deprotonate and PPh3 triphenylphosphine), was synthesized in dichloromethane reactions between PdCl2 a mixture Hdz PPh3. The new Pd(II) has been identified by FT-IR, electronic spectra, DFT calculations, molar conductivity, single-crystal X-ray diffraction. An diffraction s...

The molecular structure of 3-methyl 2-vinyl pyridinium phosphate (3M2VPP) has been optimized by using Density Functional Theory B3LYP hybrid functional with 6-311++G (d, p) basis set in order to find the whole characteristics complex. theoretical structural parameters such as bond length, angle, and dihedral angle are determined DFT methods well agreed single crystal X-ray diffraction parameter...

the influence of cation-π interactions on the strength and nature of intramolecular o...h hydrogen bond has been investigated by quantum chemical calculations in orthohydroxy benzaldehyde (hba) compound. ab initio calculations have been performed at mp2/6-311++g** level of theory. vibrational frequencies and physical properties such as chemical potential and chemical hardness of these compounds...

to determine the non-bonded interaction energies between naphthalene and b12n12 nano ring in different orientations and distances, geometry of molecules with b3lyp method and 6-31g* basis set optimized. also reactivity and stability of naphthalene alone and in the presence b12n12 nano ring checked. then calculated the nbo, nmr, freq, nics and muliken charge of naphthalene atoms alone and in the...

the concept of resonance assisted hydrogen bond (rahb), which usually occurs in b diketons, has a remarkable role in chemistry. these molecules, which contain heteroatom particularly o and n, are species with biological interest in protein folding and dna pairing. therefore, the amplification of hydrogen bonds strength by substituents may be important in life sciences. in the current research, ...

The density functional theory (DFT) calculations at the level of B3LYP/6-31G was carried out on the structure 4(5)-Imidazole-carbaldehyde-N(5)-phenylthiosemicarbazone (ImTPh) in gas phase using Gaussian 03. Dipole moment (Debye), energy of structure formation (HF; kcal/mol) and point group, NMR parameters such as isotropic shielding (σiso) and anisotropic shielding (σaniso), σ11, σ22 and σ33 ob...

Protective coatings applied to cathodes help overcome interface stability issues and extend the cycle life of Li-ion batteries. However, within 3D cathode composites it is difficult isolate effect coating because additives non-ideal interfaces. In this study we investigate niobium oxide (NbO x ) as in a thin-film model system, which provides simple access cathode-coating-electrolyte interface. ...
