4. A computational study on Gauche Effect of C8H15O-X (X: OH, NH2, CH3) Conformers

Ghazaleh Kouchakzadeh

Volume 10, Issue 1 , Winter 2020, Pages 26-30

Abstract
  Theoretical calculations of chemical hardness and stability energy on C8H15O-X (X: OH, NH2, CH3) carried out by NBO at the B3LYP/6-311+G** level. C8H15O-X have been two distinguishable conformations: one CO-anti position, and the other CO-gauche position. This calculations confirm importance of LP2O16→ ...  Read More

5. Quantum hard spheres in a slit pore

Abbas Helmi

Volume 10, Issue 1 , Winter 2020, Pages 31-38

Abstract
  In this paper, the density functional theory is employed to investigate the effects of quantum correction on the structure and such thermodynamic properties of quantum-mechanical hard sphere fluids confined in nano-slit pore as excess adsorption and wall pressure. It is found that the repulsion between ...  Read More

6. Advance polymeric membrane to CO2 separation

S Bandehali; Abdolreza Moghadassi

Volume 10, Issue 1 , Winter 2020, Pages 39-50

Abstract
  Global CO2 emissions have increased steadily due to use of fossil fuels and industrial applications. Therefore, it is necessary to decrease of energy consumption and CO2 concentration by CO2 separation from natural gas. There are different technologies to CO2 separation. CO2 separation membranes prepared ...  Read More
