“…However, SWCNTs exhibit more distinctive electrical and optical properties when compared to MWCNTs. On the other hand, MWCNTs show more chemical resistance than SWCNTs [4]. This characteristic is of significant importance when functionalization is required which means the surface structure of pristine CNTs is modified by chemical methods to meet the requirements of desired specific application.…”

a b s t r a c tCarbon nanotubes (CNTs) are pure carbon in nanostructures with unique physico-chemical properties. They have brought significant breakthroughs in different fields such as materials, electronic devices, energy storage, separation, sensors, etc. If the CNTs are ever to fulfill their promise as an engineering material, commercial production will be required. Catalytic chemical vapor deposition (CCVD) technique coupled with a suitable reactor is considered as a scalable and relatively low-cost process enabling to produce high yield CNTs. Recent advances on CCVD of CNTs have shown that fluidized-bed reactors have a great potential for commercial production of this valuable material. However, the dominating process parameters which impact upon the CNT nucleation and growth need to be understood to control product morphology, optimize process productivity and scale up the process. This paper discusses a general overview of the key parameters in the CVD formation of CNT. The focus will be then shifted to the fluidized bed reactors as an alternative for commercial production of CNTs.

“…46 One study has shown a similar effect in weakly acidic solutions with pristine kappa-carrageenan hydrolyzing to poligeenan. 47 Despite this loss in conductivity over storage, dopamine oxidation proceeded similarly in both new and 3-month old solutions of GO:KC. Upon the addition of 5.75 μM DA, an oxidation peak of 0.23 V and 0.22 V for the bare GCE and film-modified electrode were observed respectively.…”

A novel electrochemical dopamine sensor was fabricated based on a composite film solely consisting of kappa-carrageenan and hierarchical porous carbon drop-casted onto a glassy carbon electrode in a conventional three electrode system. Graphene oxide was synthesized in a one-step thermal conversion from base-catalyzed alkali lignin. Five ratios by mass of a novel hierarchical porous activated carbon and kappa-carrageenan were studied for dopamine quantification without synthetic binders such as polytetrafluoroethylene. Various tests were performed to explicate structure and electrochemical properties of the films. Utilizing differential pulse voltammetry for detection, the optimized 10:1 ratio system elicited a linear range of 1–250 μmol l−1 and a limit of detection of 0.14 μmol l−1 (S/N = 3). Results suggested an effective new combination of materials for non-enzymatic dopamine sensing.

“…Carbon nanotypes have various features such as nanoendurance morphology, high resistance, suitable surface to increase the ratio of the electric and magnetic properties (electrical permeability factor), and high permittivity . Single‐walled nanotubes have less strength than multiwalled nanotubes . One of their most important features is their functioned surface that makes them very suitable for the sensor .…”

Aluminum‐doped strontium hexaferrite nanoparticle SrAl1.3Fe10.7O19 was prepared by sol–gel method and polyaniline (PANi) multiphase magnetic nanocomposite SrAl1.3Fe10.7O19/MWCNT/PANi was synthesized through a sonochemical method by in situ polymerization. The morphology, structure, and magnetic properties of the nanocomposites are investigated by field emission scanning electron microscopy, X‐ray powder diffraction, Fourier transform infrared spectroscopy, and vibrating sample magnetometer. The electromagnetic interference shielding efficiency was evaluated in the KU‐band (12.4–18 GHz). The reflection loss (RL) value showed that the composites have an excellent absorbing property in the KU‐band, minimum −24.93 dB at 16.40 GHz with a bandwidth of 2.81 GHz (shielding effectiveness up to 10 dB) at a matching thickness 6.5 mm. The RL value of the SrAl1.3Fe10.7O19/MWCNT nanocomposite was −15.92 dB at 15.84 GHz with a bandwidth of 1.66 GHz (with a shielding effectiveness up to 10 dB). These results disclose the remarkable microwave shielding ability of SrAl1.3Fe10.7O19/MWCNT/PANi in KU‐band due to the interactive effect of the three components. © 2017 Wiley Periodicals, Inc. J.
