    Abstract In this study, hierarchical ZnS–CNT hybrids were synthesized via a solvothermal reaction at 180 °C for 48 h, producing ∼200 nm ZnS spheres uniformly anchored onto oxidized multiwalled carbon nanotubes. Structural analyses by XRD confirmed the cubic sphalerite phase, while SEM and TEM revealed a “pearl-necklace” morphology and effective nanoparticle dispersion. XPS spectra verified Zn2+ and oxygen-containing surface groups on the composite. Nitrogen adsorption–desorption measurements showed that incorporating CNTs transformed the material’s isotherm from type III to type IV, increasing the BET surface area from 68 to 155 m2 /g and introducing mesoporosity.

    Journal of Renewable Materials, Vol.11, No.4, pp. 1601-1612, 2023, DOI:10.32604/jrm.2023.023213 - 01 December 2022

    Abstract This work aims to prepare chitosan (CS)-based coated layers, CS (10 wt% nanosilver/90 wt% CS, 10 wt% biotin/90 wt% CS, and 5 wt% nanosilver–5 wt% biotin)/90 wt% CS coatings are prepared, onto pure Ti substrate. The surface morphology of the novel CS composite coating was studied using field emission scanning electron microscopy, atomic force microscopy (AFM), Fourier transforms infrared (FTIR) and wettability test. Results show that the addition of (biotin, nanosilver) 5 Vol.% improves the properties of composite materials. Using different particles’ scale size aid in improving the combinations in the alginate, producing a dual… More > Graphic Abstract
