A novel, single-step, environmentally-friendly, water-based, spray-coating approach to obtain superhydrophobic and superoleophobic nanocomposite coatings made from materials with low bioaccumulation.
Negative differential resistance and effect of defects and deformations in MoS2 armchair nanoribbon metaloxide-semiconductor field effect transistor Atomistic simulation is used to study the structure and energy of defects in monolayer MoS 2 and the role of defects on the mechanical properties of monolayer MoS 2 . First, energy minimization is used to study the structure and energy of monosulfur vacancies positioned within the bottom S layer of the MoS 2 lattice, and 60 symmetric tilt grain boundaries along the zigzag and armchair directions, with comparison to experimental observations and density functional theory calculations. Second, molecular dynamics simulations are used to subject suspended defect-containing MoS 2 membranes to a state of multiaxial tension. A phase transformation is observed in the defect-containing membranes, similar to prior work in the literature. For monolayer MoS 2 membranes with point defects, groups of monosulfur vacancies promote stress-concentration points, allowing failure to initiate away from the center of the membrane. For monolayer MoS 2 membranes with grain boundaries, failure initiates at the grain boundary and it is found that the breaking force for the membrane is independent of grain boundary energy.
