In this study, a continuous fiber laser (1064 nm wavelength, 30 W/cm²) is used to irradiate multi-walled carbon nanotubes (MWCNTs) on different substrate surfaces. Effects of substrates on nano-welding of MWCNTs are investigated by scanning electron microscope (SEM). For MWCNTs on silica, after 3 s irradiation, nanoscale welding with good quality can be achieved due to breaking C-C bonds and fo...

Recent advancements in nanotechnology have proposed the Carbon nanotubes as electrode material for the Supercapacitor applications due to their unique properties. Synthesis of Carbon nanotube in Catalytic Chemical vapor deposition (CCVD) is the easiest and economic way of production in a larger scale. The synthesized MWCNTs were characterized by X – ray diffraction (XRD). The morphological char...

Studies have proved that increasing polymer matrices by carbon nanotubes to form structural reinforcement and electrical conductivity have significantly improved mechanical and electrical properties at very low carbon nanotubes loading. In other words, increasing polymer matrices by carbon nanotubes to form structural reinforcement can reduce friction coefficient and enhance anti-wear property....

The current paper provides an overview to emphasize the role of functionalization of multiwalled carbon nanotubes (MWCNTs) in manipulating cure kinetics of epoxy nanocomposites, which itself determines ultimate properties of the resulting compound. In this regard, the most commonly used functionalization schemes, that is, carboxylation and amidation, are thoroughly surveyed to highlight the rol...

A water-soluble acid oxidized multiwall carbon nanotube o-MWCNTs -polythiophene composite for bilayer photovoltaics is reported. Discrete heterojunction photovoltaic cells utilizing this nanocomposite material as the donor layer exhibit a 20% increase in fill factor and commensurate increase in power conversion efficiency as compared to cells without o-MWCNTs. Crucially o-MWCNTs are incorporate...

Multi-walled carbon nanotubes (MWCNTs) have been used in the oxidative dehydrogenation of 9,10-dihydroanthracene in an organic solvent (toluene) using molecular oxygen as the oxidant, and in the absence of trace amounts of metals. The process is very selective and almost no anthraquinone is formed. Thermal treatment of the MWCNTs at 2600 °C favors deoxygenation of the support and markedly impro...

The creep and dynamic mechanical behavior of natural fiber/epoxy composites using functionalized multiwalled carbon nanotubes (MWCNTs) modified matrix were investigated. 0.4 wt% of MWCNTs functionalized with carboxylic acid groups (MWCNTs-COOH) were dispersed in epoxy and three-phase multiscale hybrid composites were processed by hot press. Natural fiber/epoxy two-phase composites without MWCNT...

An efficient multi-walled carbon nanotube/gold colloidal nanoparticle paste electrode (MWCNTs/ Au Nps PE) was prepared for detection of hydrazine in the presence of pyrogallol red as a mediator in the homogenous solution. The prepared MWCNTs/ Au Nps PE and multi-walled carbon nanotube paste electrode (MWCNTs PE) were characterized by Raman spectroscopy, scanning electron microscopy and cyclic v...

This paper reports the success of amino-functionalization on multi-walled carbon nanotubes (MWCNTs) to promote neuronal cells growth on MWCNT electrode for extracellular recording, attributed to the formation of positive charge of NH(2) molecules on their surfaces. Besides, the surface of MWCNT electrode becomes hydrophilic after amino-functionalization (AF-MWCNTs) which can enhance electrical ...

As a type of emerging nanomaterial, hydroxylated multiwalled carbon nanotubes (OH-MWCNTs) may interact with other pollutants in the aquatic environments and further influence their toxicity, transport, and fate. Thus, evaluation of toxicity to arsenic in the presence of CNTs needs to receive much more attention. The present study was conducted to explore the underlying mechanisms of OH-MWCNT-in...
