In this research, Quantum-mechanical calculations were performed at the HF method with the 6-31+G*basis set and at the B3LYP method with the 6-31+G* basis set in the gas phase and five solvents such as water, DMSO, methanol, ethanol and dichloromethane at six temperatures. According to these theoretical results of IR, we extracted thermo chemical parameters such as enthalpy (∆H Kcal/mol), Gibbs...

Parvin-e E`tesami, the daughter of Yousef E`tesami, was one of the eminent poets of the constitutional period. Her father, E`tesam al-Molk was a remarkable intellectual. He was one of the very first translators and one of the writers whose work started Romanticism in Iran in the last years of Qajar dynasty.

The aim of this study is to investigate the application of polypyrrole/ polyaniline (PPy/PANI) nanofiberfor Cu (II) sorption from paper mill wastewater. The tests and their optimization results were basedon the experiments design in three levels of variables using Taguchi method. The results showed thatin Copper removal tests, the pH of the solution was the most effective para...
