Thermally Induced Microstrain Relaxation, Morphological Evolution, and Pseudocapacitive Performance of Multiphase Yttrium-Substituted Nickel Ferrite Composites Synthesized via Co-precipitation

Structural, Morphological, and Electrocatalytic Activity of GdMn0.5M0.5O3 (M = Cr, Fe, Co) Perovskites

GdMn0.5M0.5O3 (M = Cr, Fe, Co) perovskites were synthesized by a glycine‐assisted solution combustion method. Phase formation and crystal structure were investigated by powder x‐ray diffraction, and Rietveld refinement confirmed single‐phase orthorhombic perovskites (space group Pnma). Refined structural parameters wer...

Annealing effect on microstructural, vibrational, magnetic, and dielectric properties of Sr0.9Co0.1Fe11.9Nb0.1O19

Structural Evolution, Defect Chemistry, and Microstructural Tuning of Novel La2-xCaxMn2-yCoyO6-δ Double Perovskite Oxides Synthesized via Facile Sol–Gel Route

Lanthanum-based double perovskite oxides (DPOs) have attracted considerable attention owing to their structural tunability, defect chemistry, and redox-active transition-metal centers, making them promising candidates for energy-related applications. In the present study, a series of novel La2-xCaxMn2-yCoyO6-δ (x = y =...

Multi-doping of Gd and Mn in BNT material: structure, microstructure, dielectric, electrical, infrared, optical properties and NTC thermistor application

Analytical investigation of co-precipitated SnO2–CuO nanocomposite: synthesis, characterization, and performance assessment

In this work, SnO2–CuO composites were synthesized in a 1:1 ratio using the co-precipitation method and calcined at varying temperatures from 300 to 600 °C. X-ray diffraction (XRD) confirmed a phase transition from semicrystalline to crystalline with increasing temperature, accompanied by crystallite growth from 8 nm t...

Temperature-Driven Formation and Consolidation of Magnetite-Type Nano-Assemblies in a PEI-Assisted Solvothermal System

Magnetite-type iron oxide nano-assemblies are widely investigated because of their strong magnetic response, chemical stability, and tunable surface chemistry. However, the lower-temperature threshold for crystalline spinel formation in polyethylenimine-assisted solvothermal systems remains insufficiently defined. In t...
