Abstract The emissions of volatile organic compounds (VOCs) have hazardous effects on humans and the environment, hence they should be detected reduced. In this study, polybenzoxazine (PBZ) amine-functionalized multiwall carbon nanotube (MWCNT) composites were synthesized as a sensor for VOCs. MWCNT functionalized with two types diamines, namely, 1,6-hexanediamine (HDA) phenylenediamine (PDA). ...

A glassy carbon electrode (GCE) coated with delafossite CuCrO2 loading on the nitrogen-doped reduced graphene oxide (N-rGO) and multiwalled nanotubes (MWCNT) composite (N-rGO-MWCNT/CuCrO2) was applied to hydrogen evolution reaction Bisphenol-A (BPA) detection. First, N-rGO-MWCNT prepared by in situ chemical reduction caffeic acid as a reducing agent. Then, accumulated surface form N-rGO-MWCNT/C...

Multiwalled carbon nanotubes (MWCNT) are fiber-shaped nanomaterials that have a potential risk for cancer due to properties similar asbestos. One type of nanotube called MWCNT-7 was categorized in Group 2B as possibly carcinogenic humans by the International Agency Research on Cancer. MWCNT-N, which is MWCNT-7, lung and pleura when administered rats via respiratory tract using intra-tracheal in...

Ceria-terbia solid solution nanobelts were prepared by an electrochemical route and tested as catalysts of high activity for CO oxidation.

Understanding and improving durability of fuel cell catalysts are currently one of the major goals in fuel cell research. Here, we present a comparative stability study of multi walled carbon nanotube (MWCNT) and conventional carbon supported platinum nanoparticle electrocatalysts for the oxygen reduction reaction (ORR). The aim of this study was to obtain insight into the mechanisms controllin...

This work aims to investigate and characterize the photo-ignition phenomenon of MWCNT/ferrocene mixtures by using a continuous wave (CW) xenon (Xe) light source, in order to find the power ignition threshold by employing a different type of light source as was used in previous research (i.e., pulsed Xe lamp). The experimental photo-ignition tests were carried out by varying the weight ratio of ...

We have manufactured a highly conductive and stretchable composite by backfilling a preformed graphene/MWCNT aerogel with poly(dimethylsiloxane) (PDMS). The electrical conductivity of our product can reach 2.8 S cm(-1) with only 1.3 wt% graphene/MWCNT loading, and remains constant after 100 times repeated stretching by 20% and 5000 times bending.

High-resolution electron microscopy was employed to characterize the interface structure of a cast Al-Mg-Si-Bi-Pb aluminium(6262)-based composite reinforced by alpha alumina particles with a trace of beta alumina in order to investigate the behaviour of alloying elements in cast composites. Except for a few primary Mg2Si particles, few reaction products were detected at the interface of Al/alph...
