In this study, silver/silver oxide nanoparticles (Ag/Ag2O NPs) were successfully biosynthesized using Phoenix dactylifera L. aqueous leaves extract. The effect of different plant extract/precursor contractions (volume ratio, v/v%) on Ag/Ag2O NP formation, their optical properties, and photocatalytic activity towards azo dye degradation, i.e., Congo red (CR) methylene blue (MB), investigated. X-ray diffraction confirmed the crystalline nature NPs with a crystallite size range from 28 to 39...
In this paper, ZnO nanoparticles (NPs) were greenly synthesized at different pH values of 4, 6, 9.5, and 11 via Portulaca oleracea leaf extract, the effect on optical structural properties was studied. UV-Vis spectrophotometers FTIR spectroscopy characterized properties. Meanwhile, Scanning Electron Microscopy (SEM) X-ray Diffraction (XRD). Furthermore, their photocatalytic dye degradation examined against methyl orange dye. The characterization results have confirmed successful biosynthesis...
In recent decades, much attention has been paid to using nanomaterials in the development of highly-sensitive sensors for environmental monitoring. This review describes how are being used develop electrochemical sensing platforms analysis (air pollution, water quality, soil nutrients, and pathogens). particular, we discuss use nanofabrication techniques (e.g., monolayer self-assembly, drop-casting, molecular imprinting, electrodeposition, situ polymerization, hydrogenation, 3D printing)...
Abstract Chitosan is one of the most abundant biopolymers in nature with high economic value due to its biocompatibility, biodegradability, lack toxicity, and antifungal activity. In this study, chitosan was extracted from three different sources: Blaps lethifera (CSB), Pimelia fernandezlopezi (CSP), Musca domestica (CSM). The ash content (AC), moisture (MC), fat binding capacity (FBC), water (WBC), deacetylation degree (DD) were determined for prepared chitosans. effect DD on antibacterial...
Meeting the escalating demands in biomedical applications has spurred creation of diverse scaffolds, where selection materials and manufacturing techniques stands as a linchpin fostering bone tissue formation. These scaffolds provide fundamental structural framework that supports cell growth differentiation. It is vital for repair, addressing various biological requisites such biocompatibility, biodegradability, mechanical properties becomes imperative. This comprehensive review discusses...
Modification of calcium carbonate particles with surfactant significantly improves the properties coating on paper. In this study, unmodified and CTAB (hexadecyltetramethylammonium bromide)- oleate-modified nanoparticles were prepared using wet carbonation technique for paper coating. (cationic surfactant) sodium oleate (anionic used to modify size, morphology, surface precipitated nanoparticles. The obtained characterized X-ray diffraction (XRD), Fourier transform infrared (FT-IR)...
