Objective: In this study, the zeolite-coated iron oxide nanoparticles were evaluated as MRI contrast agent and effect of the nanocomposite synthesis method on MRI contrast was tested. Materials and Methods: Ion exchange method was used for synthesis of iron oxide-zeolite and the as prepared nanocomposite was characterized by XRD, FESEM and TEM. The nanocomposite toxicity in the cell culture, a...

A nanocomposite of polyaniline (PANI) with natural clinoptilolite (Clino) was prepared by chemical oxidative polymerization of anilinium cations in the presence of clinoptilolite dispersion. The PANI/Clino nanocomposite was characterized using FTIR, XRD and SEM techniques as well as electrical conductivity measurement using four point probe technique. Cyclic voltammetry analysis was used to inv...

in this scientific research, for the first time, the removal of radioactive strontium-90 (90sr) by γ-mno2-aga zeolite as a novel nanocomposite adsorbent was accomplished under different conditions such as ph, temperature, adsorbent amount and the contact time that are examined from drinking water of ramsar city and monitored via ultra low-level liquid scintillation counting (lsc) technique. pri...

Nanotechnology enables development and production of novel silver-based composite materials. We used in vitro tests to demonstrate the antimicrobial activity of a silver-silica nanocomposite compared to the activities of conventional materials, such as silver nitrate and silver zeolite. A silver-silica-containing polystyrene material was manufactured and shown to possess strong antimicrobial pr...

in this research, zeolite-tio2 nanocomposite was prepared for degradation of dibenzothiophene as a typical aromatic organosulfur compound of transportation fuels.the synthesized tio2 was immobilized on the surface of clinoptilolite by solid state dispersion (ssd) method. the nanocomposite was then characterized by xrd, ftir, tem and sem techniques. photodegradation of dibenzothiophene in n-hexa...

Objective- The present study was aimed to evaluate repair of a critical segmental defect of rabbit femur using the rabbit’s femoral defects repaired by Zeolite and Zeolite/Collagen scaffolds Design- Experimental Study Animals- Forty-five mature male New Zealand white rabbits Procedures- The animals were randomly divided into three groups of 15 animals each. In the first group...

The preparation of polyaniline/zeolite nanocomposite coating on 304 stainless steel (304 SS) surface has studied via the galvanostatic method. The electro-generated coating was characterized by Fourier transform infrared spectroscopy (FT-IR), UV-visible absorption spectroscopy, X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). The anticorrosion property of polyaniline/zeo...

Abstract Nanocomposite has gain great attention in many applications due to its better properties nanoscale. Chitosan-Zeolite-ZnO nanocomposite were prepared via sol-gel method and analysed by molecular docking study predict antiviral activity against SARS CoV-2. The CoV-2 glycoprotein as receptor from RCSB PDB complex ligand of Chitosan-Zeolite ZnO chosen interaction model between receptor. Ac...
