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...
we study the coherent spin-polarized transport through a zigzag-edge graphene flake (zgf), using hubbard model in the nearest neighbor approximation within the framework of the green function’s technique and landauer formalism. the system considered consists of electrode/ (zgf)/electrode, in which the electrodes are chosen to be armchair nanoribbons. the study was performed for two types of ele...
sp(2)-Bonded boron nitride aerogels are synthesized from graphene aerogels via carbothermal reduction of boron oxide and simultaneous nitridation. The color and chemical composition of the original gel change dramatically, while structural features down to the nanometer scale are maintained, suggesting a direct conversion of the carbon lattice to boron nitride. Scanning and transmission electro...
