“…In addition, their high electrical conductivity has aroused interest in the area of electrical appliances and communication-related applications [2,3]. The strength and flexibility of CNTs have made them applicable to the other nanometric structures [4]. One of the ways to study the features of CNTs is simulation.…”

The present study reports an eco-friendly, biosynthesis of silver nanoparticles (AgNPs) using stem bark extract of Diospyros montana. Initially, the synthesis of AgNPs was confirmed by visual observation as color change. Further, the morphology of the biosynthesized nanoparticles, average size and presence of elemental silver were characterized by UV-Visible spectroscopy, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray and dynamic light scattering spectrometer. Qualitative phytochemical screening and FTIR spectral peaks supported the role of phytochemicals in bark extract for the metal reduction, stabilization and capping of silver nanoparticles. XRD studies demonstrated that crystalline nature and their average size of nanoparticles was 28 nm as determined by Scherrer's formula. The antioxidant ability of AgNPs and plant extract was analyzed using DPPH and Hydrogen peroxide assay. The percentage of DPPH and H 2 O 2 activity was increased with increasing concentration of AgNPs. In vitro antibacterial effect of various concentration of AgNPs was investigated against both Gram positive (B.subtilis and S.aureus) and Gram negative (E.coli and K.aerogenes) bacterial strains. The result shows that biosynthesized AgNPs have significant antibacterial activity.

“…C arbon nanotubes (CNTs) have potential applications in many fields, including composite materials, energy storage, electronics, catalysis, etc. [1][2][3][4] Multi-walled CNTs (MWCNTs) are today produced at large scale under the form of powders by various companies at relatively low cost. [5] However, the surface of the as-produced MWCNTs is hydrophobic and chemically inert, which limits their large-scale applications.…”

Large‐scale oxidation of multi‐walled carbon nanotubes in fluidized bed from ozone‐containing gas mixtures

et al. 2017

100 g of multi‐walled carbon nanotubes (MWCNTs) tangled in balls of 388 μm in Sauter diameter were treated per run in a pre‐industrial scale fluidized bed reactor, using ozone‐based gaseous mixtures at ambient temperature. The influence of ozone concentration and of the addition of water vapour was studied, for treatment durations between 1 h and 20 h. The process behaviour was analyzed in terms of fluidized bed pressure drop and temperature profile. The nature and amount of the grafted oxygen based functions were analyzed, as the structural modifications created. An oxidation mechanism in two steps was evidenced, showing the grafting of hydroxyl, phenol, and ether functions in a first step and then of lactone, quinone, carbonyl, and carboxylic groups. A moderate etching of the MWCNT outer walls was observed. The amount of grafted functions and of structural defects increased with treatment duration and was highly exalted by the presence of water vapour. All the results obtained showed that the oxidation was uniform on the whole powder of the bed and from the outer part to the centre of the balls, probably thanks to the high fluidization quality maintained all along the ozone treatment.

The stacking of the metal complex [(5,6-dimethyl-1,10-phenanthroline)(1S,2S-diaminocyclohexane)platinum(II)] 2+ (56MESS) onto the surface of two different fullerenes, a carbon nanotube, and a C 60 -buckyball was examined. The metal complex forms a supramolecular complex with multi-walled carbon nanotubes (CNTs) but not with C 60 -buckyballs. Binding of 56MESS to the CNTs is highly efficient (90 %) but can be further stabilized by the addition of the surfactant, pluronic F-127, resulting in a loading efficiency of 95 %. Molecular modelling shows that binding of 56MESS to the CNTs is supported by the large surface area of fullerene, whereas the more pronounced curvature and lack of a flat surface on the buckyballs affect the ability of 56MESS to form bonds to its surface. The loading of 56MESS onto the CNTs is via π-π stacking from the metal complex phenanthroline ligand and C-H···π bonding from the diaminocyclohexane ligand. 56MESS has 13 critical bonding points with the CNTs, eight of which are π-π stacking bonds, but the metal complex forms only seven bonds with the buckyballs. In addition, the loading of 56MESS onto the CNT results in a charge transfer of -0.111 eV. However, charge transfer is almost negligible for binding to the buckyball.The anticancer metal complex [(1,10-phenanthroline)(1S,2S-diaminocyclohexane)platinum (II)] 2+ forms a supramolecular complex with multi-walled carbon nanotubes through π-π stacking.
