Abstract Carbon fibre/fabric (CF) is a privileged reinforcement for advanced polymer composites in tribological applications where performance is primary criteria rather than the cost due to the combination of distinct properties such as high specific strength, thermo-oxidative resistance, thermal and electrical conductivity along with self-lubricity etc. However problems associated with its ch...

This work reports a novel and general synthesis of aligned carbon nanotube/polymer composite films with high optical transparency, robust flexibility, and excellent conductivity. These composite films show many potential applications such as flexible conductors for optoelectronic devices.

We report the spectroscopic changes of tetraphenylporphyrin carbon nanotube composites in a variety of chlorinated solvents such as chloroform, dichloroethane and dichlorobenzene as a result of sonication. Detailed data analysis suggests that protonation of the porphyrin core nitrogen atoms occurs as a result of sonodegradation of the solvent molecules. Extreme care must be taken when working w...

For the first time, lithiation/delithiation behavior of tellurium at room temperature was investigated using tellurium/porous carbon (Te/C) composite electrodes. The Te/C composite is synthesized by the infusion of liquid tellurium into a porous carbon host at the high temperature of 600 C under vacuum. Owing to the physical confinement of Te by porous carbon matrix, the Te/C electrode is capab...

In the implementation of Carbon Nanotube Reinforced Polymer matrix Composites in structural applications, deflection and stress analysis are important considerations. In the present study, a multi scale analysis of deflection and stress analysis of carbon nanotube (CNT) reinforced polymer composite plates is presented. A micromechanics model based on the Mori-Tanaka method is developed by intro...

Nanoscale carbon has been making headlines for more than two decades. Whether furled up in carbon nanotubes or assembled into cagelike fullerenes, carbon at the atomic scale shows great potential in everything from photovoltaics to ultra-strong composite materials. Now, graphene -thin, planar sheets of carbon -promises to advance photonics with improved detectors, display circuitry, and even em...

Porous graphitic carbon nitride/carbon composite spheres were synthesized using melamine and cyanuric acid, and glucose as the carbon nitride and carbon precursor, respectively. The 3D hierarchical composites efficiently catalyzed the oxygen reduction reaction with an onset potential of 0.90 V and a kinetic current density of 23.92 mA cm(-2). These merit their promising applications in fuel cel...

imperialist competitive algorithm (ica) is a new socio-politically motivated global search strategy. the ica is applied to hybrid composite laminates to obtain minimum weight and cost. the approach which is chosen for conducting the multi-objective optimization was the weighted sum method (wsm). the hybrid composite laminates are made of glass/epoxy and carbon/epoxy to combine the lightness and...
