“…Additionally, capping agents are not necessary because the solvent can have a slight stabilizing effect on nano-phases that have already been created [32]. The highly reactive NPS obtained via LAL can be modi ed further right away by adding particular ligands or functionalities using ow reactors because they are so reactive as-prepared [33]. The characteristics of the produced nanoparticles can be tailored using a variety of experimental factors, such as laser system parameters [34].…”

This study aims to bio-modulate Poly (vinyl alcohol) crosslinked by silver and gold nanoparticles fabricated via one-step laser ablation. The structural, optical, and antibacterial properties of the fabricated samples were investigated via different techniques. FTIR and XRD were used to investigate the molecular structures of the polymer matrix of Polyvinyl Alcohol incorporating gold and silver (Ag-Au NPs) created by laser ablation. XRD data illustrate the semicrystalline structure of PVA, with two hump peaks at 2θ = 8.52o and 2θ = 20.17o that are decreased when loaded with Ag-Au nanoparticles at different laser ablation times. The FT-IR spectra demonstrated a variation in the intensity of various peaks compared to the spectrum of the Polyvinyl Alcohol. This suggests that PVA and Ag-Au nanoparticles interacted and complexed in semicrystalline areas. The optical energy gap (Eg) reduces from 5.55 eV to 5.00 eV during the direct transition and from 4.79 eV to 3.10 eV during the indirect transition. The cell viability value for sample S2 was 91.7 ± 5.8%, indicating that both nanocomposites are biocompatible. The values of S2, indicate that both nanocomposites are biocompatible. S2 represents the high values of the inhibition zone, which make it preferred in antibacterial applications. The results demonstrate that Polyvinyl Alcohol/metal composite materials have excellent optical and electrical properties, implying that they may be employed in energy devices.

Amorphous zero-valent iron (AZVI) has attracted wide attention due to its high-efficiency reduction ability. However, the effect of different EDA/Fe(II) molar ratios on the physicochemical properties of the synthesized AZVI requires further investigation. Herein, series of AZVI samples were prepared by changing the molar ratio of EDA/Fe(II) to 1/1 (AZVI@1), 2/1 (AZVI@2), 3/1 (AZVI@3), and 4/1 (AZVI@4). When the EDA/Fe(II) ratio increased from 0/1 to 3/1, the Fe 0 proportion on the AZVI surface increased from 26.0 to 35.2% and the reducing ability was enhanced. As for AZVI@4, the surface was severely oxidized to form a large amount of Fe 3 O 4 , and the Fe 0 content was only 74.0%. Moreover, the removal ability of Cr(VI)

“…However, hollow structures of Cu, Fe, and Al oxides were formed in deionized water. 55 Similarly, bimetallic (Al 2 O 3 @Ag) and trimetallic (Al 2 O 3 @AgAu) NPs were synthesized using nanosecond PLA in deionized water. The Al 2 O 3 @AgAu showed improved catalytic activity in the reduction of 4-nitrophenol (4-NP) as compared to the Al 2 O 3 @Ag.…”
