Abstract:
Density functional theory (DFT) has been employed within the generalized gradient approximation and Perdew-Burke-Ernzerhof functional (GGA-PBE) to study the structural and electronic properties of nitromethane (NM) surface models. Different surfaces, including (100), (001), (101), (110), and (111), are considered in this work. The corresponding properties of bulk crystal for NM were also calculated to form a contrast to the slab models. Results with anisotropic characteristics of different surfaces have been observed in this study. There was an obviously great anisotropy in electronic parameters, especially the band gaps of different surfaces, indicating the anisotropic impact sensitivity along different directions of NM. The band gap value for (111) surface, 2.687 eV, was smaller than that of other surfaces, showing a higher impact sensitivity for NM. The estimated anisotropy has been revealed in surface energies for different surfaces. Graphical Abstract The valence band minimum (VBM) and conduction band maximum (CBM) of the nitromethane (100), (001), (101), (110) and (111) surface models.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
Surface Tension and Surface Energy
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...
