Herein we describe the development, characterization and application of an electrochemical sensor based on the use of Nafion/MWCNT-modified screen-printed carbon electrodes (SPCEs) for the voltammetric detection of the anti-tuberculosis (anti-TB) drug ethambutol (ETB). The electrochemical behaviour of the drug at the surface of the developed Nafion/MWCNT-SPCEs was studied through cyclic voltamm...

BACKGROUND This study aimed at verifying the action of multi-walled carbon nanotubes (MWCNT) under the naturally transformable Neisseria meningitidis against two different DNA obtained from isogenic mutants of this microorganism, an important pathogen implicated in the genetic horizontal transfer of DNA, causing the escape of the principal vaccination measured worldwide by the capsular switchin...

In this novel study, some factors that affect the enrichment efficiency of multi-walled carbon nanotubes (MWCNTs) towards some pesticides in environmental water samples were studied. The effect of oxidation of MWCNTs with various oxidizing agents and the effect of length and external diameter of MWCNTs were investigated. Model pesticides were selected from various common categories of pesticide...

BACKGROUND Removal of pathogens from water is one way to prevent waterborne illness. In this paper, we developed dual functional carbon nanotube (CNT) modified filters for bacterial capture and inactivation, utilizing multi-walled CNTs (MWCNTs) to coat on commercially available filters and making use of the exceptional adsorption property of CNTs to adsorb a natural antimicrobial peptide-nisin ...

Pool boiling experiments were conducted with three horizontal, flat, silicon surfaces, two of which were coated with vertically aligned multiwalled carbon nanotubes (MWCNTs). The two wafers were coated with MWCNT of two different thicknesses: 9 m (Type-A) and 25 m (Type-B). Experiments were conducted for the nucleate boiling and film boiling regimes for saturated and subcooled conditions with l...

Using electrospinning technique, well-aligned poly(azo-ether-imide) (PAEI) nano-fibers and PAEI/multiwalled carbon nanotube (MWCNT) nano-fibers were developed in this effort. Afterwards, polystyrene-b-poly (ethylene-ran-butylene)-b-polystyrene (SEBS) and polyimide-based nano-fiber films were casted. The as-prepared electrospun nanofibers acted as homogeneous reinforcement to enhance the tensile...

Micro powder injection moulding-μPIM is a powder injection moulding-PIM variant for microparts/devices. This study is about the optimization and respective production of nanocomposites feedstocks suitable to μPIM process. The optimization of MWCNT content in metal matrix composites-MMC feedstock were performed using torque rheometry until achieve homogeneous feedstocks with suitable flowability...

BACKGROUND Multi-walled carbon nanotubes (MWCNT)s are suspected to induce pulmonary and pleural cancers due to their asbestos-like configurations. Therefore, accurate measurement of inhaled nanotubes in target organs is crucial for assessing cancer risk. Conventionally, nanotubes are measured after combustion at high temperature for conversion into CO2; however, the sensitivity is poor and the ...

: A simple procedure was developed for the fabrication of electrochemical glucose biosensors using glucose oxidase (GOx), with graphene or multi-walled carbon nanotubes (MWCNTs). Graphene and MWCNTs were dispersed in 0.25% 3-aminopropyltriethoxysilane (APTES) and drop cast on 1% KOH-pre-treated glassy carbon electrodes (GCEs). The EDC (1-ethyl-(3-dimethylaminopropyl) carbodiimide)-activated GOx...

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). ...
