We perform ab initio density functional calculations to study the flow of water, methanol, and dimethyl ether through nanotubes carbon boron nitride with different diameters chiralities. The liquids we choose are important solvents, water methanol being polar nonpolar. In terms activation barriers for liquid transport, find molecular-level drag decrease decreasing nanotube diameter but be rathe...

Natural materials with hyperbolic responses can confine light with well-defined propagation directions inside the micro/nanostructure. Here we theoretically demonstrate that strong resonance absorption can be achieved in one-dimensional gratings made of hexagonal boron nitride (hBN) due to hyperbolic phonon polaritons. The radiative properties of both trapezoidal and square resonators are calcu...

In this paper, free vibration analysis of a polymer-based nano-composite beam reinforced by boron-nitride nanotubes and subjected on elastic foundation, is studied. Smooth and defect-free nanotubes with uniform and directly- orientated in matrix are intended. Also, nanotubes’ distribution in the thickness direction of beam is regarded as a uniform distribution of the three different targeted on...
