Nanotechnology is a branch of science that that has opened new research horizons, particularly in the field of ofmedicine and cancer treatment.In the present paper, magnetite nanoparticles (Fe3O4) were produced by the co-precipitating of two and three valent iron chloride salts in an alkaline medium. The surface of the nanoparticles was functionalized with (3-Aminopropyl)-trimethoxysilane(APTS), and finally the cisplatinanticancer drug was loaded onto the modified nanoparticles. Properties, structure and morphology of the nanoparticles obtained were evaluated and analyzed by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Vibrating Sample Magnetometer (VSM) for measuring MAGNETIC properties. Results showed that cisplatinwas attached to the surface of the nanoparticles confirmed by FT-IR analysis. MAGNETIC properties using VSM results showed that the NANOCOMPOSITE is the result of superparamagnetism. Findings showed that MAGNETIC cisplatin MAGNETIC NANOCOMPOSITEs are promising for targeted MAGNETIC drug delivery and can be used as a targeted nanoparticle suitable for delivering anticancer drugs.

Gas separation by a MEMBRANE is performed without phase changing, leading to cost reduction. This study investigates the process of gas separation in the case of polyacrylonitrile (PAN) and polysulfone (PSF) blend MEMBRANEs. The ratios of polymers to mixed matrix MEMBRANEs include 100% PAN, 100% PSF, (95% PAN{5% PSF), (90% PAN{10% PSF), (85% PAN{15% PSF). The best combination of MEMBRANE mixtures was determined. Then, iron oxide nanoparticles with di erent weight percentages were placed on the MEMBRANE. The impact of adding di erent amounts of iron oxide nanoparticles to the MEMBRANE on gas separation was examined. By adding iron oxide nanoparticles to the MEMBRANE by 10% weight and measuring the value of permeability, it was observed that the permeability of this MEMBRANE for carbon dioxide, oxygen, nitrogen, and methane gases increased by 117%, 137%, 95%, and 53% compared to MEMBRANEs without iron oxide nanoparticles. Based on the  ndings, it was revealed that the optimal value of adding iron oxide to improve the MEMBRANE properties was 10% by weight.

Wetting of polymeric hollow fiber MEMBRANEs by chemical absorbents is one of the main challenges of gasliquid MEMBRANE contactors. This s tudy explored an appropriate method to fabricate a superhydrophobic polypropylene (PP) hollow fiber MEMBRANE by incorporating fluorinated silica nanoparticles (fSiO2 NPs) on the PP MEMBRANE surface. The effect of the hydrophobic agent on the water repellent properties of the composite MEMBRANE was s tudied by varying (1H, 1H, 2H, 2H-perfluorooctyltriethoxysilane/ tetraethylorthosilicate) (PFOTES/TEOS) molar ratio from 0 to 1. The composite MEMBRANEs were characterized using field emission scanning electron microscopy (FESEM), attenuated total reflection-Fourier transform infrared (ATR-FTIR), contact angle, mechanical s trength and s tatic wettability. The obtained results showed that the surface hydrophobicity and mechanical s trength of the composite MEMBRANEs increased compared to pure ones. The contact angle of 156°,was obtained when the (PFOTES/ TEOS) molar ratio was 0. 5. Furthermore, the CO2 absorption experiment was done to evaluate the performance of the fabricated MEMBRANEs in a gas-liquid MEMBRANE contactor. The obtained results showed that the PP/fSiO2 composite MEMBRANE has more potential to be used in gas-liquid MEMBRANE contactors than commonly used polymeric MEMBRANEs.
