This study presents nonlinear vibration of functionally graded-graphene platelet-reinforced composite (FG-GPLRC) beams under various time-dependent forces. Their material distributions are characterized by continuous functions with four patterns reinforcement which uniform, linear and parabolic I II. The third-order shear deformation theory is used to represent the displacement fields, while ge...

This study indicates the analysis of functionally graded carbon nanotube reinforced composite (FG-CNTRC) plates using a four-node quadrilateral element related to C0-type Reddy’s third-order shear deformation theory (C0 HSDT) and cell-based smoothed strains (CS) strategy. is surely taking advantages desirable properties theory. Besides, FG-CNTRC with advanced material are changed from bottom to...

While several approaches have been developed for sorting metallic (m) or semiconducting (s) single-walled carbon nanotubes (SWCNTs), the length of SWCNTs is limited within a micrometer, which restricts excellent electrical performances of SWCNTs for macro-scale applications. Here, we demonstrate a simple sorting method of centimetre-long aligned m- and s-SWCNTs. Ni particles were selectively an...

This study investigates the efficacy of two-dimensional (2D) carbon and inorganic nanostructures as reinforcing agents for cross-linked composites of the biodegradable and biocompatible polymer polypropylene fumarate (PPF) as a function of nanostructure concentration. PPF composites were reinforced using various 2D nanostructures: single- and multiwalled graphene oxide nanoribbons (SWGONRs, MWG...

Single wall Carbon Nanotubes (SWCNTs) are hydrophobic and do not disperse in aqueous solvents. Acid functionalization of SWCNTs results in attachment of carboxy and sulfonate groups to carbon atoms and the resulting acid functionalized product (AF-SWCNTs) is negatively charged and disperses easily in water and buffers. In the present study, effect of AF-SWCNTs on blood erythrocytes was examined...

Local chemical functionalization of single-walled carbon nanotubes (SWCNTs) has been developed as a means defect doping to enhance the near infrared photoluminescence properties materials. Wavelength-tunable and exciton trapping-induced bright emission appears from locally functionalized SWCNTs (lf-SWCNTs). Molecularly designed lf-SWCNTs based on our approach produce new dynamic switching funct...

The nonlinear buckling analysis of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) plates subjected to axial compression load is analytically examined in this paper. Assuming that the FG-CNTRC are stiffened by an oblique stiffener system. Reddy’s higher-order shear deformation plate theory (HSDPT) with geometrical nonlinearities von Kármán applied establish basic formulation...

The assembly of single-walled carbon nanotubes (SWCNTs) using the AC dielectrophoresis technique is studied theoretically. It is found that the comb electrode bears better position control of SWCNTs compared to the parallel electrode. In the assembly, when some SWCNTs bridge the electrode first, they can greatly alter the local electrical field so as to "screen off" later coming SWCNTs, which c...
