Ahmadi
In this research, the complexation of a new recently synthesized phenothiazine with 10 different metals was evaluated by Density functional theory. At the first step, the structures of 6,15-diazabenzo[a][1,4]benzothiazino[3,2-c]phenothiazine, cations and their complexes with the mentioned material were optimized geometrically. Then, IR calculations were performed on them to obtain the values of formation enthalpy and Gibbs free energy. The acquired results indicate that Cu2+ forms the most stable and strongest complex with 6,15-diazabenzo[a][1,4]benzothiazino[3,2- c]phenothiazine. Hence, this substance can be utilized as an outstanding ionophore or a potential ligand in the determination of copper by ion selective electrodes and different extraction methods respectively. All calculations were applied by Density functional theory in the level of B3LYP / 6-31G(d).

Investigation of High-energy Heterocyclic Synthesis as a Green Fuel from the Reaction of 3,6-D-aminotrazine with Nitric acid and Sodium azid; Under Different Temperature Conditions, by DFT Method
Fatima
Alzahar
In this research, the synthesis of heterocyclic explosives (ATTz) from the reaction of 3,6-D-amino-tetrazine with Nitric acid and sodium azide were studied under different temperature conditions using the functional density theory method. For this purpose, the materials were first geometric optimization reaction sides, then the thermodynamic parameters were calculated for all of them. Then, the values of ΔH, ΔG, ΔS of this reaction were obtained at different temperatures as the sum of these parameters in the products to the raw materials. Finally, the best temperature for the synthesis of explosives was evaluated according to the thermodynamic parameters.

Surface Adsorption of Carbon Monoxide and Hydrogen Gases Mixed with Boron Nitride (7 ,7) Nanotubes by Monte Carlo Method
Leila
Asgar
In this project, the pure adsorption of mixtures of hydrogen and carbon monoxide on nanotubes (7 and 7) of boronitrile nanotubes was studied by Montecarlo method. The potential for the interactions of gases with each other and with a nanotube according to the Lennard-Jones equation and its parameters are calculated according to Lawrence-Bartwell rules for interaction between gas, gas and gas-nanotubes. Simulation of adsorption of gases at different temperatures and pressures and the results of gas adsorption density are calculated and compared in each case. The results show that the adsorption of gases is directly related to the increase of pressure and with the increase of temperature, the relation is opposite. Comparison of the results shows that absorption is higher in pure state.

A Comparative Study of the Carbonyl Positioning Mechanism in the Mn (CO) 5 CH2F and Mn (CO) 5CHF2 Complex through Quantum Chemistry
Zahra
Pakdel
In this study, quantum computation was performed by density functional theory (DFT) on carbon monoxide CO placement in Mn (CO) 5CH2F and Mn (CO) 5CHF2 complexes, and all structures were geometric optimization and the CO deposition mechanism in different states on They were evaluated. The pathway for locating the reaction in both complexes was through the migration mechanism of the alkyl group. The initial complex will have four different paths to reach the product. The computational result shows that a path is preferable to other paths, which is attributed to spatial and electron effects.
