The thermodynamic and magnetic properties of the mixed spin (1/2-1) hexagonal Ising nanowire (HIN) system with core-shell structure have been presented by means of the effective-field theory (EFT) with correlations. The effects of the physical parameters of the system on thermodynmaic and magnetic properties (magnetizations, susceptibilities, internal energies, and free energies and hysteresis curves) are investigated for both ferromagnetic and antiferromagnetic case, in detail. One can find that when the temperature increases the hysteresis loop areas decrease and the hysteresis loops disappear at above critical temperature. Moreover, different hysteresis loop behaviors have been observed such as single, double and triple hysteresis loops in the system. In order to confirm the accuracy of the phase transition points, we also investigate the free energy of the system.

“…It was found that CNTs reinforced composites have prominent enhancement in the properties, such as hardness [6], bending strength, fracture toughness [7], wear resistance [8], corrosion resistance [9], electrical conductivity [10] and thermal stability [11]. Therefore, these properties make CNTs very useful for supporting Fe₂O₃ in many potential applications [12]. In this study, electrophoretic deposition (EPD) was used to make the MWCNT/α-Fe₂O₃ composite material.…”

In recent years, photocatalytic technology has received attention for environmental protection. In this study, the usefulness of iron nanostructures generated by anodization was confirmed. Moreover, the synergistic effect of anodized iron (hematite, α-Fe₂O₃) and MWCNT (multi-walled carbon nanotube) was confirmed by methylene blue (MB) decomposition by MWCNT /α-Fe₂O₃ composite material. Electrophoretic deposition(EPD) was used as a method of making the MWCNT/α-Fe₂O₃ composite material. Characterization of the anodized samples and samples after EPD was performed by SEM and XRD, and concentration measurement of MB decomposition was performed using a spectrophotometer. The MB decomposition rate was improved in all the samples with MWCNT and the highest obtained with the MWCNT/α-Fe₂O₃ sample

“…Such advantages show that magnetic CNTs may have great analytical potential as effective adsorbent for determination of some compounds. 39,40 To the best of our knowledge, their analytical potential has been the subject of little research that has focused primarily on the development of synthetic methods and characterization of the resulting products.…”
