Polyvinyl alcohol (PVA)/Polyethylene oxide (PEO) has been blended and doped with zinc titanium nanoparticles. Different concentration of the prepared ZnO TiO2 NPs make a change in PVA/PEO- ZnO/TiO2 nanocomposites films improve characterization PVA/PEO. XRD scans show two broad peaks at about 18.8° 21.95° for PVA/PEO blend. obtain hexagonal structure anatase phase NPs. The addition dopants blend results reduce degree crystallinity compared to pure This is evident from decrease index (Xc...
The polymeric material polyvinyl pyrrolidine/carboxymethyl cellulose (PVP/CMC) was mixed with different quantities of tungsten-trioxide nanoparticles (WO3 NPs). samples were created using the casting method and Pulsed Laser Ablation (PLA). manufactured analyzed by utilizing various methods. halo peak PVP/CMC located at 19.65°, confirming its semi-crystalline nature, as shown in XRD analysis. FT-IR spectra pure composite incorporated contents WO3 obtained a shift band locations change...
This paper presents the design and analysis of a new compact quad-band metamaterial absorber (MMA). The proposed structure is constructed as an array 12 × 13 unit cells, each one based on combination interlaced I/square resonators supporting four distinct resonant frequencies. cell printed FR-4 substrate with thickness 1.5 mm size 20 mm. MMA exhibits absorption peaks at 2.248, 2.878, 4.3 5.872 GHz rates 96, 93, 95 %, respectively, under normal incidence. achieves negative permittivity...
Abstract Our study focused on the optical behavior, methylene blue (MB) dye degradation potential, antibacterial performance, and silver trioxide mineral interaction with different bacterial species. We found that addition of nanoparticles (Ag NPs) to neodymium oxide (Nd 2 O 3 ) resulted in a significant response, an enlargement inhibition zone for species such as Staphylococcus aureus Escherichia coli. Specifically, S. increased from 9.3 ± 0.5 mm pure Nd 16.7 0.4 Ag/Nd nano-composite, while...
Long-term biocompatible scaffolds based on chitosan (CS) encapsulated with hydroxyapatite (HAP) have been developed for orthopedic applications. The biocomposites consisting of magnesium (Mg)/strontium (Sr) co-dopant into [email protected] were fabricated using a casting technique, whereas Mg(II) contribution was varied. crystal growth seems to be in the c-axis upon rising content, c/a ratio changed from 0.72 0.73. Moreover, it suggested that ions prefer substitute Ca(1) rather than Ca(2)...
This study aims to bio-modulate Poly (vinyl alcohol) crosslinked by silver and gold nanoparticles fabricated one-step laser ablation. The optical, cell viability, antibacterial characterization of the films have been studied via different techniques. FTIR XRD were used investigate molecular structures polymer matrix Polyvinyl Alcohol incorporating (Ag-Au NPs) created data illustrate semicrystalline structure PVA, with two hump peaks at 2θ = 8.52° 20.17° that are decreased when loaded Ag-Au...
