“…The R ct between the metal and solution interface was determined as the reason for the high-frequency semicircular arc in the Nyquist diagram. The larger the diameter of the semicircular arc, the larger is the R ct value, indicating a longer diffusion path of the corrosion ions from the solution to the metal surface . Although the corrosion kinetic process of the ZSO material is not significantly different from that of the ZnO material, the ZSO shielding layer always has the largest resistance radius throughout the experiment.…”

The unique characteristics of rare earth elements, attributed to their distinctive 4f electron band, hold significant potential for enhancing the stability and effectiveness of inorganic anticorrosion materials. In this study, rod-shaped samarium-doped zinc oxide solid solution (ZSO) material was synthesized under pure inorganic conditions. The protective effect of the 4f electrons of samarium on the 3d electrons of zinc enhances the chemical stability of the material. Furthermore, the ZSO material exhibited the ability to utilize photogenerated electrons for preventing metal corrosion. Tests have shown that the corrosion resistance of the ZSO composite shield is 78.3% higher than that of the zinc oxide shield and 202.3% higher than that of the epoxy resin coating. Under sunlight, the ZSO composite shield exhibits further improved corrosion inhibition efficiencies of 40% and 100%. The protective effect may be extended to other rare earth and transition metals, leading to the development of more stable and durable materials.

“…In addition, as the particle size decreased, the magnetic moment decreased, and the magnetic property weakened. However, as the particle size increased, the magnetic moment increased, and the magnetic properties strengthened [20]. Temperature also affects the Curie temperature of the magnetic cobalt-cuprumzinc ferrites, affecting their magnetic properties [21].…”

Magnetic cobalt-cuprum-zinc ferrites were prepared from anhydrous ethanol using the combustion method, and their structure and properties were characterized using the XRD, SEM, EDS, and VSM techniques, and its formation mechanism was discussed. The magnetic Co0.4Cu0.2Zn0.4Fe2O4 nanoparticles calcined at 400 oC with 25 mL anhydrous ethanol were used for the removal of methyl blue (MB). The results showed that the pseudo-second-order kinetic model best agreed with the adsorption method. In addition, analysis of the adsorption isotherms using the Freundlich, Langmuir, and Temkin models showed that theTemkin model was most consistent with experimental results, which revealed that the adsorption of MB onto the Co0.4Cu0.2Zn0.4Fe2O4 nanoparticles was a multi-molecular layer chemisorption. Further, the influence of pH on the adsorption capacity was evaluated and was highest at pH 11. The cyclability and removal rate of the nanoparticles were explored. The removal rate was approximately 80% after 7 cycles, revealing that the magnetic CoxCuyZn(1-x-y)Fe2O4 nanoparticles are important for wastewater treatment.

“…These implantationinduced defects might be favourable to achieve a desired number of acceptors in the case of p-type ZnO. Compared to other ion implantations, [36][37][38][39][40][41] few pieces of literature are available, which have focused on Li implantation in ZnO thin films. [42][43][44] In an attempt to make ZnO p-type, Nagar et al 44 have shown that Li implantation into ZnO thin films displays ntype conductivity even after employing annealing treatment due to the presence of donor defects.…”
