عنوان انگلیسی I-9: Modal Analysis of Carbon Nano Tubes (CNT) by Means of Finite Element Technique
چکیده انگلیسی مقاله Objective: The applications of nanotechnology concepts to medicine joins two important cross-disciplinary fields with many potential applications arising from the natural combination of specific achievements in each of the two respective fields. The common basis evolves from the molecular-scale properties relevant to the two fields. Mechanical approaches and molecular imaging techniques allow surface and interface properties to be characterized on a nanometer scale at predefined locations, while chemical approaches offer the opportunity to elaborate and address surfaces, e.g., for specified drug delivery, enhanced biocompatibility, and neuroprosthetic Purposes. Transferring functional nanodevices into individual cells for therapeutic or diagnostic usage is one of the greatest visions of modern nanoscience. In order to achieve these aims novel structures and materials have to be developed which meet the various demands of such nanomedical applications. Carbon nano tubes (CNT) are mechanically and chemically thin walled carbon structures which can be functionalized both exohedrally and by filling with a functional material. A comprehensive dynamic behavior of CNT is necessary to suppress adverse effects so that CNT provide a smart carrier system on the nanometer scale. The present presentation sets out to investigate the modal shapes and frequencies of vibrations of carbone nanotubes. Three cases of supports are considered i. free-clamped ii. hinged-clamped and iii. clamped-clamped. Finite element model of the continuous system is analyzed using ANSYS software. The presentation concludes with a feasibility study of the device in medicine and healthcare as a drug delivery system, and transducers.
