The catalytic activity of molybdenum disulfide (MoS2) is associated with active sites located along the edges, whereas the MoS2 basal plane is regarded to be inert. However, it is a great challenge to develop a rational way for producing active edges

Layered transition metal dichalcogenides have distinct physicochemical properties at their edge-terminations. The production of an abundant density of edge structures is, however, impeded by the excess surface energy of edges compared to basal planes

The conventional method of modeling CMUTs use the isotropic plate equation to calculate the deflection, leading to deviations from FEM simulations including anisotropic effects of around 10% in center deflection. In this paper, the deflection is foun
