From density functional theory calculations, we elucidated the reaction mechanism of CO 2 reduction on silicene nanoflakes. According to the results, silicene monoflakes present a notable catalytic activity for the hydrogenation of CO 2 . The most probable energetically favorable reaction pathway is formic acid and formaldehyde production, with energy barriers ranging between 16 and 24.1 kcal/mol. At the same time, transforming carbon dioxide to methanol, carbon monoxide, and methane requires higher activation energies. This theoretical perspective provides significant insights into silicene-based materials and their potential applications as CO 2 conversion to fuel and value-added chemicals.

The prediction of the volume of bubbles released from a nozzle is of importance to Industries employing non-Newtonian liquids. It has been shown in this work that equations of the type V = C(Q2lg)313 can be used to predict the volume of bubbles In liquids displaying both shear dependent viscosity and viscoelasticity provided the gas rates are higher than about 0.5 X 10~6 rrr/s.
