The use of intelligent nanocomposites in sensing and actuation applications has become quite common over the past decade. In this article, electro-thermo-mechanical nonlinear dynamic buckling of an orthotropic piezoelectric nanocomposite (PNC) cylindrical shell conveying viscous fluid is investigated. The composite cylindrical shell is made from Polyvinylidene Fluoride (PVDF) and reinforced by ...

To determine the non-bonded interaction between methyl benzoate and boron nitridenanotube, we focused on an armchair single-wall boron nitride nanotube (9,9) With length 5 angstroms.The geometry of molecules was optimized using B3LYP method with 6-31g* basis set. Also reactivityand stability of methyl benzoate and boron nitride nanotube (9,9) was checked. Then NBO, FREQ,...

In this study, the adsorption of 4-hydroxy phenyl-azobenzene on the surface of (4, 0) zigzag open-end boron nitride nanotube (BNNT) has been investigated by quantum calculations. In order to find the preferred adsorption site, different positions and orientations were considered. The impacts of donor-acceptor electron delocalization on the structural and electronic properties and reactivity of ...

New means for activating covalent bonds in organic compounds are crucial further advancing application fields from pharmaceuticals to plastics syntheses. The manufacturing of almost every daily product can be impacted by the development such bond activations. However, traditional catalysts these transformations faced with challenges as catalyst stability, recyclability, or energy demand. Due th...
