Summary: This study investigates the structural, electrical and transport properties of cobalt nanoferrites (CoFe2O4) doped with dysprosium cation (Dy3+) on the iron (Fe3+) site. The results confirm that the samples maintain a pure cubic spinel structure. The average crystallite size ranges from 49 to 72 nm and is not affected by the concentration of Dy3+ ions. The lattice parameters vary from 8.34 Å for pristine CoFe2O4 to 8.39 Å for the sample with the highest doping concentration (Dy(x) = 0.15). The porosity decreases with increasing Dy3+ ion concentration. The electrical properties are analyzed through dielectric behavior at different frequencies and temperatures. The ferrite with Dy(x) = 0.15 exhibits the highest dielectric constant in the range of 441 to 5234, indicating its suitability for memory storage devices.

Summary: The solution casting technique was used to synthesize film samples of hydroxypropyl methylcellulose (HPMC)/poly vinylalcohol (PVA) blends embedded with various concentrations of copper oxide (CuO) nanoparticles. The research focused on the structural analysis, conductivity properties, and electrical characteristics of the polymer electrolytes. The results showed that increasing the concentration of CuO decreased the crystalline size and percentage of crystallinity, thereby affecting the conductivity properties. The uniform dispersion of nano CuO in the polymer was confirmed through surface morphology and phase formation analysis. Frequency and temperature analysis revealed that the AC conductivity increased with increasing frequency and temperature. The findings of this study have important implications for the application of these nanocomposite polymer electrolytes in electrochemical cell devices.

Summary: Four different samples of Nickel ferrite (NiFe2O4) with varied morphology and nanoparticle size were synthesized using different methods: electrospinning, hydrothermal, green, and sol-gel. Characterization of the prepared powders was performed through XRD, FT-IR, SEM, TEM, and BET techniques. The ferrite exhibited a cubic spinel phase with nanofiber, nanotube, nanorod, and nanosphere structures. The conductivity values were dependent on the size and morphology of the nanoparticles, and their semiconducting behavior was observed. The dielectric constant, dielectric loss, and ac conductivity of the samples at different temperatures and frequencies were studied.

Summary: In this study, a film of a carborane-thiol-protected tetranuclear copper cluster with characteristic orange luminescence was fabricated and utilized using ambient electrospray deposition. The clusters were deposited at an air-water interface to form a film by charged microdroplets produced by an electrospray tip. The porous surface structure of the film was characterized by different microscopic and spectroscopic techniques. Visible and rapid quenching of the emission of the film upon exposure to 2-nitrotoluene vapours under ambient conditions was observed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
