“…This result can be attributed to the blockage of a part of SBA-15 pores by Fe 3 O 4 NPs incorporating on the pores of SBA-15 and its consequent modications, which led to a reduction in accessible surface area for gas adsorption. 13,49 In Table 1, the BJH pore size distributions of the prepared sample and compounds are shown. It can be seen that the SBA-15/Fe 3 O 4 sample has a slightly larger pore size (diameter) and also has relatively broader pore size range than its precursor matrix.…”

In this work, the rapid, facile, and eco‐friendly green process was introduced in the preparation of β ‐cyclodextrin/magnetic iron oxide nanoparticles by using the aqueous Mentha longifolia extracts of Mentha longifolia . The obtained nanoparticles were characterised by Fourier transform infrared spectroscopy, x‐ray powder diffraction, field emission scanning electron microscope, and thermogravimetric analysis. Also, effective factors on the synthesis of magnetic nanocomposites including temperature, concentration of the Mentha longifolia extract, and concentration of FeSO 4 solution were optimised by Taguchi design. Moreover, important effective parameters on the adsorption efficiency; such as adsorbent dosage, pH, contact time, and temperature were investigated. The prepared magnetic nanocomposite was applied as a nanocarrier for imatinib mesylate delivery. In vitro studies confirmed imatinib mesylate release over 6 h. The nanocarrier showed pH‐dependent imatinib mesylate release with higher drug release at simulated cancer fluid (pH = 5.6) compared to neural fluid (pH = 7.4). Moreover, the sorption isotherms and kinetics for the magnetic nanocomposite were fitted into Langmuir and pseudo‐second order models, respectively. Based on the thermodynamic results, the adsorption of imatinib mesylate onto the nanoadsorbent was found to be spontaneous and exothermic.

“…Therefore, it can be deduced that the SiO 2 nanoparticle is a good choice for improving the stability of other nanoparticles. However, recovery and reusability of nanoparticles can be a serious problem because the main methods for the separation of nanoparticles are filtering and drying, − which can lead to an increase in the costs of nanoparticle recovery in industrial scales. In contrast, magnetic nanoparticles can easily be collected by an external magnetic field. − …”

In this work, the absorption of carbon dioxide (CO2) using functionalized Fe3O4 magnetic nanofluids was investigated. Nanoparticles of Fe3O4, Fe3O4–proline, Fe3O4–lysine, and Fe3O4@SiO2–NH2 were dispersed in water and methyldiethanolamine (MDEA) in order to improve the absorption performance using a high-pressure setup, in which CO2 and absorbents were in direct contact in a closed system. The effects of initial pressure of CO2, nanoparticle type, and nanoparticle concentration on absorption performance were examined. The obtained results indicated that the presence of functionalized Fe3O4 nanoparticles resulted in better results at pressure 30 bar in distilled water as a physical absorbent, and they enhanced the absorption up to 17.61 and 34.23% compared to nonfunctionalized Fe3O4 and distilled water, respectively. Subsequently, the dispersed nanoparticles in MDEA solution showed that the functionalized Fe3O4 nanoparticles were effective for CO2 separation even in chemical absorbents, and under the best conditions, they enhanced the capacity of absorption up to 16.36% at pressure 40 bar. Moreover, zeta potential analysis revealed that Fe3O4–lysine and Fe3O4@SiO2–NH2 nanoparticles are more stable than nonfunctionalized Fe3O4 and Fe3O4–proline in the base fluid.
