n this paper, modification of Multi-walled carbon nano tubes (MWCNTs) with stearic acid (SA) was done using wet chemical method. For this aim MWCNTs were treated with high concentrated nitric acid to create functional group ...

Based on strain gradient theory with surface energy, a non-classical Euler-Bernoulli beam

model is developed to study the vibration and stability behavior of micropipes conveying

fluid. Applying Hamilton’s principle, the equation...
