Oxygen vacancy formation energies are often used as a descriptor of the catalytic activity of metal oxides for oxidation reactions having the Mars-van Krevelen mechanism. When these energies are calculated, it is often assumed that they depend only on the concentration of the vacancies in the top oxygen layer. Previous work has shown that in the case of TiO2 and V2O5, the energy of vacancy formation depends not only on their concentration but also on the manner in which they are distributed on the surface. However the energy change due to the change of configuration in these systems is very small. Here we find that in the case of α-MoO3(010) the dependence on the energy of vacancy formation of the distribution of vacancies is very large: if the lattice made by the vacancies consists of parallelograms, the energy of vacancy formation is 0.4 eV smaller than when the lattice consists of rectangles (the two systems having the same vacancy concentration).

In the present research work, the experimental analysis was conducted on Polyvinyl ester/Glass Fiber composite with Alumina (Al 2 O 3), Molybdenum disulfide (MoS 2) and Titanium oxide (TiO 2) fillers. Polymer composites offer numerous advantages for the high strength to weight ratio due to low density, high modulus, and better stiffness. Low strength and ductility of Polyesters, vinyl-esters, and epoxy cannot be applied for technical applications, hence reinforced by fiber and fillers to form composite matrices. The increase in % of filler has enhanced the ultimate strength monotonously except for 12.5% of Tio 2 filler in the polyvinyl ester/GF composites. The addition of Al 2 O 3 filler has better Young's modulus compared to other fillers and maximum Young's modulus was observed for 12.5% Al 2 O 3 and there is a drastic increase in Young's modulus to almost 40% compared with 7.5% Al 2 O 3 polyvinyl ester composite. Flexural strength of particulate filled polyvinyl ester composite composites improved due to strong interfacial adhesion and the surface roughness act as mechanical interlocking. It is also evident that the addition of MoS 2 filler is more beneficial than that of Al 2 O 3 filler in improving the flexural strength and modulus of polyvinyl ester/GF composite. The SEM study was conducted to infer the results obtained for the tensile and flexural tests conducted for the polyvinyl ester/GF composite.
