In the present study, lead titanate nano-sized powders were synthesized using citric acid gel method. The nanopowders characterized X-ray diffraction (XRD) and scanning electron microscopy (SEM). Then, a nanocomposite system based on carbon paste electrode (CPE) was designed applied for determination of pentoxifylline (PTX). prepared nanostructured exhibited voltammetric responses with high sensitivity selectivity PTX detection limit 2.1 nM achieved. Finally, proposed method used analysis in...
Renewable and sustainable energies are vital for the near future. Hydrogen, as a clean energy carrier, is potential candidate supplying in foreseeable Nowadays, hydrogen storage technology has become significant issue sector. In this study, ZnCo2O4/ZnO MgCo2O4/MgO nanocomposites have been synthesized using sol-gel method with stearic acid complexing agent. Different analyses were studied to examine crystal structure, morphology, physical properties of as-prepared samples, including X-ray...
Abstract In this study, new nanocomposite membranes from sulfonated poly (ether ether ketone) (SPEEK) and proton-conducting Fe 2 TiO 5 nanoparticles are prepared by the solution casting method. Sulfonated core–shell synthesized redox polymerization. Therefore, 4-Vinyl benzene sulfonate (VBS) 2-acrylamide-2-methyl-1-propane sulfonic acid (AMPS) grafted on surface of through radical The different amounts hybrid (PAMPS@Fe PVBS@Fe ) incorporated into SPEEK matrix. results show higher proton...
Abstract In this research, we successfully synthesized magnesium aluminate (MgAl 2 O 4 ) spinel nanoparticles using a sol-gel process, with stearic acid serving as capping agent. The synthesis process involved calcination at 900 °C for h, resulting in the formation of an average crystallite size approximately 12 nm, determined through Debye–Scherrer analysis and X-ray diffraction (XRD) data. optical band gap was measured 2.84 eV Diffuse Reflectance Spectroscopy (DRS) analysis. Additionally,...
Abstract Carbon nanotubes (CNTs) have the potential to serve as delivery systems for medicinal substances and gene treatments, particularly in cancer treatment. Co-delivery of curcumin (CUR) Methotrexate (MTX) has shown promise treatment, it uses fewer drugs side effects. This study used MTX-conjugated albumin (BSA)-based nanoparticles (BSA-MTX) enhance assess efficiency CUR. In-vitro cytotoxicity tests, DLS, TEM, FTIR, UV/Vis, SEM, DSC studies assessed formulations' physical chemical...
In this work, an anodic stripping voltammetry for nanomolar determination of diltiazem with a chemically modified carbon paste electrode (CMCPE) containing Co3O4/SnO2 nanopowders was studied. The accumulation potential and time were selected at, −0.2 V 190 s, respectively. electroanalytical performance the CMCPE evaluated regarding composition, solution pH, accumulation, interferences. novel showed linear response to concentration range 50–650 nM lowest detection limit value 15 nM....
Iron titanate nanopowders with a particle size range of 48–70 nm could be obtained after calcinations the dried gel at 900°C for 2 h. Fe2TiO5 indicates ferrimagnetic–paramagnetic behaviour, as evidenced by using vibrating sample magnetometer room temperature. In temperature 25–300°C empirical equation heat capacity C p (J/mol K) = −692.328 + 1.39 T 3.757 × 107/T was determined from differential scanning calorimetry. Direct optical band gap calculated Tauc model UV-Vis diffuse reflectance...
Abstract LaCrO 3 perovskite nanopowders were successfully prepared via a sol-gel method using stoichiometric proportion of materials containing lanthanum and chromium in stearic acid complexing agent. Structural analysis indicated an octahedral framework its XRD pattern bearing crystallite size the range 28 nm. The particle sizes confirmed by morphological scanning sample. optical properties clearly interesting activity UV visible ranges. degradation activation energy (E d ) was calculated...
