[ 1 ] - Validation of Shell Theory for Modeling the Radial Breathing Mode of a Single-Walled Carbon Nanotube (RESEARCH NOTE)
In this paper, the radial breathing mode (RBM) frequency of single-walled carbon nanotube (SWCNT) is studied based on the thin shell theory. For this purpose, SWCNT is considered as an elastic thin cylindrical shell. The dynamic equation of RBM is derived using the Hamilton’s principle. An analytical solution of the RBM frequency of SWCNT is obtained. The advantage of this formulation is that i...
[ 2 ] - Acousto-Refrigerator with an Adjustable Mechanical Resonator (RESEARCH NOTE)
Thermoacoustics describes energy conversion processes, activated by interaction temperature oscillation, accompanying the pressure oscillation in a sound wave, with solid boundaries. In ordinary experience this interaction of sound and heat cannot be observed, because of the very low temperature differences, but under suitable conditions, it can be emphasized and amplified to create remarkable ...
