In spite of different economic agents’interests, as well as the Administration’s effort inpromoting extensive beef-producing systems over thelast years, this kind of activity still hasn’t reached thedesirable levels, being necessary that farmers perceivean appropriate benefit which...

The electronic structure of S adsorption on goethite (110) surface has been studied by ASED-MO cluster calculations. For S location, the most exposed surface atoms of goethite surface were selected. The calculations show that the surface offers several places for S adsorption. The most...

The electronic structure of H2S adsorbed on the goethite (110) surface has been studied by ASED-MO cluster calculations. We have studied both the perpendicular and the parallel H2S molecular adsorption on the FeOOH(110) surface. We have analyzed the adsorption configuration energies including...

The interaction of hydrogen with a platinum (111) cluster using the atom superposition and electron delocalization–higher binding ASED-TB quantum calculation method was studied. The metal surface was represented by a Pt cluster of seven layers. The effect of hydrogen on this metal substrate...

The Fe–C–H interaction near defects in iron structures was studied using qualitative structure calculations in the framework of the atom superposition and electron delocalization molecular orbital. Calculations were performed using three Fe clusters to simulate an edge dislocation, a...
