Highly efficient nanomembranes from hybrid PVC-DAP reinforced with Ag NPs for use in water purification and dialysis devices the medical field.
Abstract Improving eco‐friendly coating‐based materials for wool artifacts, such as kilim fabric can inspire new‐fashion design avenues conserving ancient cultural heritage. Thus, this research addresses an efficient treatment agent from natural rosin acids (R) and dapsone (D) with variable sublethal proportions of synthesized titanium dioxide nanoparticles (TiO 2 NPs) (i.e., 0.1%, 0.3%, 0.6%) modifying (KF) using a dip‐coating method. The nanostructure prepared TiO their particle size were...
The growing awareness of the importance bacterial-resistant surfaces has increased since COVID-19 pandemic global problem. Therefore, need for antibacterial become urgent. by-product bagasse papers (BPs) were modified with antimicrobial natural rosin, followed by synthesised graphene oxide and silver nanoparticles (GO-Ag-NPs) through a spin coating approach. samples exhibited remarkable activity towards E. coli (G−ve bacteria) S. aureus (G+ve bacteria). microstructure, as well phase...
Abstract In the present work, Cerium (IV)-Zirconium (IV) oxide nanoparticles (CeO 4 ZrNPs) was successfully dispersed into Chitosan/15Gelatin nanocomposites with different quantities. The obtained chitosan-based represented remarkable improvements in structural, morphological, mechanical, and thermal properties. Roughness increased from 74 nm to 6.4 nm, Young’s Modulus enhanced 1.36 GPa 2.99 GPa. influence of CeO ZrNPs contents on phase transition temperature ( T g ) non-isothermal...
In this paper, we demonstrated, for the first time, aluminum titania nanoparticle (Al-TiO2 NP) composites with variable amounts of TiO2 NPs as nonprecious active catalysts electrochemical generation H2. These materials were synthesized by mixing desired hydrogen titanate nanotubes (TNTs), fabricated here a cost-effective approach at moderate hydrothermal conditions, powder (purity 99.7%; size 35 μm). The mixture was compacted under an applied uniaxial stress 300 MPa followed sintering 500 °C...
This study aimed to investigate different types of glasses based on the 46V2O5-46P2O5-(8-x) B2O3-xCuO system in terms their nuclear radiation shielding properties. Accordingly, five CuO-doped vanadate were investigated extensively determine necessary gamma parameters along with effective conductivity at 300,000 and buildup factors. Phy-x PSD software was used for determination these vital parameters. Furthermore, parameters, such as half value layer, tenth mean free path a broad energy range...
