Abstract Iron oxide nanoparticles (IONPs) are widely used for biomedical applications due to their unique magnetic properties and biocompatibility. However, the controlled synthesis of IONPs with tunable particle sizes crystallite/grain achieve desired functionalities across single‐domain multi‐domain size ranges remains an important challenge. Here, a facile synthetic method is produce iron nanospheres (IONSs) controllable crystallinity tunability. First, highly crystalline Fe 3 O 4 IONSs...
Nickel-zinc ferrite (NZF) compounds, renowned for their mixed spinel structures, hold significant promise diverse applications in high-frequency devices and biomedicine. This study utilizes solvothermal synthesis to produce NZF nanoparticles (NPs) with tunable diameters ranging from 40 300 nm. These NPs exhibit polycrystalline crystallite sizes tailored be approximately 8 nm, a pivotal factor preserving superparamagnetic (SPM) properties across broad size spectrum. A combination of scanning...
Surface modification of silica-coated magnesium ferrite nanoparticles (MgFe2O4@SiO2 NPs) by 3-aminopropyltriethoxysilane (APTES) shows enhanced selectivity for the removal Congo Red (CR) from both single and binary aqueous dye solutions. Before coating surfaces amine-functionalized (MgFe2O4–NH2 with silica, control studies adsorption cationic, neutral, anionic dyes were performed using systems. The found that MgFe2O4–NH2 nanoadsorbent favors indigo carmine (IC) CR in solutions (>90%...
Harmful algal blooms impact human welfare and are a global concern. Sargassum spp., type of algae or seaweed that can potentially bloom in certain regions the sea around Thailand, exhibits noteworthy electron capacity as sole reducing stabilizing agent, which suggests its potential for mediating nanoparticle composites. This study proposes an eco-friendly microwave-assisted biosynthesis (MAS) method to fabricate silver nanoparticles coated with aqueous extract (Ag/AgCl-NPs-ME)....
Surface deposition of magnesium ferrite nanoparticles (MgFe2O4 NPs) with bimetallic gold/silver (Au/Ag) was conducted using the seed-mediated growth method to obtain magnetic–metallic composite catalysts for use in catalytic reduction nitroaromatics. Two types amine-functionalized MgFe2O4 and MgFe2O4@SiO2 NPs were used as magnetic supports surface process. The combination several characterization analyses (i.e., XRD, XPS, TEM, SEM, EDS, VSM) confirmed successful syntheses MgFe2O4/Au/Ag...
The emerging contaminant 2,4-dichlorophenoxyacetic acid (2,4-D) has been shown to have harmful effects on the environment and human health. These contaminants present a critical challenge in water remediation. Herein, magnetic composite composed of silica-coated magnesium ferrite nanoparticles glutaraldehyde-cross-linked polyethylenimine polymer (i.e., MgFe2O4@SiO2/GA-PEI composite) was synthesized use as an effective adsorbent for removal 2,4-D. successful preparation using optimal...
In t his study, solid silica nanoparticles (sSiO2 NPs) were chemically etched using sodium hydroxide solution as an etchant to synthesize porous (pSiO2 NPs). Etchant dosage and etching time optimized obtain the optimum condition providing effective removal of paraquat (PQ). High efficiency PQ by synthesized pSiO2 NPs was obtained over 90% 11.1 mL 1.25 M NaOH 12 h for process. SEM TEM images showed that porosity increased with increase time. The increment enhanced efficiency. FTIR result...
Magnesium ferrite (MgFe2O4) and silica-coated MgFe2O4 nanoparticles were grafted with poly(cysteine methacrylate) (i.e., MgFe2O4/PCysMA MgFe2O4@SiO2/PCysMA nanocomposites) to study pH-tunable adsorption enhanced capacities for the of anionic indigo carmine (IC) cationic methylene blue (MB) dyes. Several characterization techniques XRD, FTIR, TGA, ζ potential analysis, VSM, FE-SEM, TEM, N2 adsorption–desorption isotherm, XPS) indicated successful syntheses these nanocomposites. The behaviors...
