Abstract The discovery of graphene has led to a rising interest in seeking quasi two-dimensional allotropes several elements and inorganic compounds. Boron, carbon’s neighbour the periodic table, presents curious case its ability be structured as graphene. Although it cannot independently constitute honeycomb planar structure, forms graphenic arrangement association with electron-donor elements. This is exemplified magnesium diboride (MgB 2 ): an layered compound comprising boron planes...
<ns3:p>The study delves into the comprehensive exploration of ceria nanoparticle synthesis, explicitly focusing on distinct variants: fuel-rich, fuel-deficient, and stoichiometric proportions. These variants are meticulously investigated using sol-gel combustion method to uncover their unique characteristics. The exceptional performance is particularly notable, as it exhibits a well-defined crystal structure balanced elemental composition. Conversely, fuel-deficient fuel-rich display altered...
A novel polysulfone–cerium oxide (Psf–ceria) mixed-matrix membrane (MMM) with enhanced γ radiation resistant property was developed. Ceria nanoparticles were synthesized by gel-combustion route and then various concentrations of ceria (0.1–2% Psf) incorporated in the polysulfone matrix to synthesize Psf–ceria MMMs. Radiation stability membranes checked doses 100, 500, 1000 kGy. characterized X-ray diffraction (XRD), photoelectron spectroscopy, small-angle scattering (SAXS), transmission...
Radiation effects on polysulfone membranes without and with incorporating nanodiamonds into the matrix.
A hybrid nanoparticle system of nanodiamond and cerium oxide (ceria) is used as a reinforcement material in order to enhance the γ-radiation stability polysulfone host membrane matrix.
This is the first study undertaken towards development of mixed-matrix membranes (MMMs) with enhanced radiation resistant attributes by reinforcement nanostructured Gd2Zr2O7 (GZO) within polysulfone (Psf) host-matrix. The describes synthesis and characterization GZO in disordered, defect-fluorite structure, having average crystallite size 31(±3) nm. Membranes prepared different loading (up to 2 w/w% Psf) are exposed γ-radiation up a dose 1000 kGy aqueous environment. effect on structural,...
Abstract Cerium oxide (ceria) contains two stable states of cerium ions (Ce 3+ and Ce 4+ ). The presence these the ability to swap from one state another ↔ ) by scavenging highly reactive oxygen species (ROS) generated radiolysis water, ensure enhanced stability polysulfone (Psf) membranes in γ-radiation environment. In this study, ROS ceria was studied. Ceria nanoparticles were found scavenge like hydroxyl radicals hydrogen peroxide (H 2 O H is due peroxidase-like catalytic activity...
Industrial wastewater, containing diverse pollutants like dyes and oils, poses detrimental environmental challenges. Membrane technology addresses this complexity well but requires tailored nanofiller modifications that enhance hydrophilicity, oleophobicity, antifouling potential for efficient separation. In context, our work focuses on developing mixed matrix membranes (PV-H-C) – PVDF, halloysite nanotubes (HNTs), ceria nanoparticles effective dye oil-water emulsion separation, enabling...
