Abstract:
Guanidinium nitrate, a non-linear optical material has been systematically studied through quantum chemical (density functional theory and Hartree Fock) methods. Studies on Mulliken charge, Frontier molecular orbitals (FMOs) and hyperpolarizability analyses have been performed. The Mulliken population analyses were carried out for the optimized molecular geometry by HF and B3LYP methods with 6-311++G(d,p) levels. The molecular orbital parameters of guanidinium nitrate have been calculated by FMO analysis. Frontier molecular orbital (FMO) analysis indicates the electron delocalization on the gu

Abstract:
The frontier orbital method showed a high informativity for the study of electron transfer in the model system 18NaCl+Na3SmF6. Structures having a high probability of electron transfer from the cathode to the samarium complex were observed when varying the transition state parameters. The influence of the full-symmetric oscillations Sm-F bonds and the boundary ion shift on the activation barrier, the frontier molecular orbitals energy and the delocalization character of the lowest unoccupied molecular orbital wave function in the samarium-containing model systems was systematically studied.

Abstract:
Amino acid-modified carbon interfaces have huge applications in developing electrochemical sensing applications. Earlier reports suggested that the amine group of amino acids acted as an oxidation center at the amino acid-modified electrode interface. It was interesting to locate the oxidation centers of amino acids in the presence of guanidine. In the present work, we modeled the arginine-modified carbon interface and utilized frontier molecular orbitals and analytical Fukui functions based on the first principle study computations to analyze arginine-modified CPE (AMCPE) at a molecular level

Double ionisation of most of the experimentally accessible diatomic molecules has been studied previously by several techniques, including Auger spectroscopy, double electron transfer, kinetic energy release, and high-level theory.

A simple empirical model is introduced to estimate double ionisation energies on the basis of orbital energies. For CO, NO, and O2, an indirect double ionisation mechanism is found, involving d

Abstract:
Abstract Corrosion is an interfacial process that occurs at the metal-liquid interface and manifests itself at the macroscopic level. To gain a better understanding of corrosion and corrosion inhibition, the primary interactions responsible for these processes are explored at a molecular level. The frontier orbital type of approach is used to explain the orbital interactions for molecule-molecule and molecule-metal surface systems. The consequences of these interactions for these two systems are also discussed.

Additionally, subsea applications in the North Sea, the Norwegian shelf and other areas of the world require corrosion inhibitors to follow strict environmental regulations. In this work

Background : Banana being a monocot and having distinct peel and pulp tissues is unique among the fleshy fruits and hence can provide a more comprehensive understanding of fruit ripening. Our previous research which translated ripening discoveries from tomato, led to the identification of six banana fruit-associated MADS-box genes, and we confirmed the positive role of MaMADS1/2 in banana ripening. The overall goal was to further elucidate the banana ripening signaling pathway as mediated by MADS-boxtranscriptional regulators. Specific objectives were: 1) characterize transcriptional profiles
