In this study, the adsorption of benzaldehyde, benzoic acid, anilinee, phenol and benzenesulfonic acid( )molecules on the surface of rutile-TiO2 (110) is investigated in detail by using the density function theory( )calculations. Interactions between the molecules and rutile surface are fully considered via quantum chemical( )analyses. These processes are evaluated as chemical adsorption with adsorption energies in the range of -12.9 to( )-31.1 kcal.mol-1. The stability of investigated configurations is contributed by the Ti···O/N electrostatic interactions( )and the O/N/C-H···O hydrogen bonds. Calculated results indicate that the adsorption capacity of these molecules( )on rutile-TiO2 (110) surface decreases in the order of -SO3H và gt

However, the study that examines the relationship between perceived risk, uncertainty and expected return (perceived investment outcome), relies on traditional and modern financial theory (behavioral finance) is extremely important for the development of the stock market.
