“…From these spectra, CNTs sample has strong peaks around 1338 cm −1 (D band) and 1583 cm −1 (G band), whereas Ag/CNTs nanocomposite sample has equivalent peaks at 1322 cm −1 and 1594 cm −1 . D band represents edges, various defects, and disordered in the carbonic structure from the vibration of sp 3 hybridization from CNTs skeleton and impurities, whereas G band comes from the zone mode in CNTs structure, assigning to the ordered sp 2 hybridization of C atoms in CNTs structure [ 45 , 46 ]. Compared to CNTs, Ag NPs/CNTs nanocomposites have a considerable frequency shift toward a lower D-band wavenumber (approximately 30 cm −1 ) due to the partial reduction in CNTs by decorating with Ag NPs on their external tubular surface, this result reveals a high level of disorder in the graphene layers of CNTs structure, as well as an increase in the number of defects, confirming the interaction between the external surface of CNTs structure and Ag NPs.…”

Silver nanoparticles (Ag NPs) were decorated with different amounts on the exterior walls of carbon nanotubes (CNTs) by a laser ablation assisted method, especially in liquid media to be applied as a good adsorption material against naphthalene. The laser ablation time was controlled the amount of decoration Ag NPs on CNTs. The prepared nanocomposite was analyzed via different analytical techniques. Ag NPs with a small size distribution of 29 nm are uniformly decorated with spherical shape on CNTs walls. The disorder degree of tubular structure and shifting of the vibrational characteristic peaks increase with the increase in the decoration of Ag NPs. After that, the prepared samples were investigated for the removal of naphthalene. These studies of loading Ag NPs with different amounts on the surface of CNTs act as a promising material for water treatment.

Human health is threatened worldwide by microbial infections. Antibiotic overuse and misuse have resulted in antimicrobial-resistant bacteria. To battle such resistant microbes, we are looking for safe and alternative antimicrobial treatments, and the advent of nanotechnology holds promise in this regard. Metal oxide nanoparticles have emerged as a promising alternative source for combating bacteria resistant to various antibiotics over the last two decades. Due to their diverse physicochemical characteristics, metal oxide nanoparticles can operate as antibacterial agents through various methods. In the present research, six types of metal oxide NPs were synthesized and characterized (XRD, FTIR, SEM with EDAX, and TEM) from different plants such as Hydrangea paniculata (for NiO NP synthesis), Plectranthus amboinicus (for ZnO-NP synthesis), and Andrographis paniculata (V2O5 NPs). On the other hand, drug-resistant pathogens were isolated from clinical samples, those who suffered from foodborne illness. V2O5 NPs produced from Andrographis paniculata plant extract have much higher bactericidal efficacy than other metal oxide NPs against all three bacterial strains. Sensitive bacteria included S. aureus and E. coli, followed by K. pneumoniae. As a result, structural characterization was used to further screen V2O5 NPs. The orthorhombic structure of the crystallites was confirmed by XRD, with an average crystallite size of 20 nm. The absorbance spectrum and functional groups were identified using UV-visible spectral analysis and FTIR. SEM and EDX identified spherical-shaped NPs, and particle size (58 nm) was confirmed by transmission electron microscopy (TEM). As a result, we hypothesized that bioinspired V2O5-NPs could be employed as a possible antibacterial agent against drug-resistant pathogenic bacteria to replace currently existing inefficient antibacterial drugs.

A novel approach toward the production of multifunctional printed technical textiles is reported. Three different metal oxides nanoparticles including titanium dioxide, magnesium oxide, and zinc oxide were prepared and characterized. Both natural wool and synthetic acrylic fibers were pretreated with the prepared metal oxide nanoparticles followed by printing using polylactic acid based paste containing acid or basic dyestuffs. Another route was applied via post-treatment of the targeted fabrics with the metal oxide nanoparticles after running the printing process. The color strength (K/S) and colorfastness properties of pretreated and post-treated printed fabrics were evaluated and compared with untreated printed fabrics. The presence of nanoparticles on a fabric surface during the coating process was found to significantly increase the color strength value of the coated textile substrates. The increased K/S value depended mainly on the nature and concentration of the applied metal oxide, as well as the nature of colorant and fabric. In addition, the applied metal oxide nanoparticles imparted the printed fabrics with good antibacterial activity, high ultraviolet protection, photocatalytic self-cleaning, and improved colorfastness properties. Those results suggest that the applied metal oxide-based nanoparticles could introduce ideal multifunctional prints for garments.
