In this paper, structural, magnetic, optical, and photocatalytic properties of core-shell structure Fe3O4@GO nanoparticles have been compared with Fe3O4 nanoparticles in the degradation of methyl blue and methyl orange. For this purpose, GO nanosheets were wrapped around the APTMS-Fe3O4 nanoparticles and then charact...

Abstract Nanofiltration is one of the most widely used membrane processes for water purification with high practical value because a large number chemical species that are separated through this process. Usually, nanofiltration, energy–consuming operations involved including generation enough pressure rejection jumps and lower molecular weight chemicals at surface membrane. Recent developments ...

In the present study, removal of dibenzothiophene (DBT) from model oil (n-hexane) was investigated using magnetic activated carbon (MAC) nano-composite adsorbent. The synthesized nano-composite was characterized by FT-IR, FE-SEM, BET and VSM techniques. The MAC nano-composite exhibited a nearly superparamagnetic property with a saturation magnetization (Ms) of 29.2 emu g-1...

in this paper the influence of two different sizes of silica particles (micro-silica and nano-silica) was studied on mechanical properties of sulfur and sulfur composite. to improve the structural properties, sulfur was plasticized using dicyclopentadiene (dcpd) and methyl styrene (mst). plasticized sulfur composite was prepared by melt blending of plasticized sulfur and silica particles. the i...

Nanosized metal oxides dispersed polymer composites constitute a fascinating class of polymer composite materials. Synthesis of such composite materials through solvent casting enhances the polymer synthetic technology. Solvent casting method was used to prepare Cobalt oxide (Co3O4) dispersed Poly (methyl methacrylate) (PMMA) nano composite<span style="text-decoration: und...

Onions contain high antioxidants compounds that fight inflammation against many diseases. The purpose was to investigate some selected bioactive activities of onion varieties (Yellow, Red, Green, Leek, and Baby). Antioxidant assays anti-inflammatory such as NO production with the addition components were determined analyzed by using a spectrophotometer. Gas chromatography mass spectrometry (GC–...

In this study, we isolated and characterized a new strain of Klebsiella sp. Y3, which was capable of decolourizing azo dyes under anaerobic conditions. The effects of physico-chemical parameters on the Methyl Red degradation by the strain were determined. The results indicated that strain Y3 exhibited a good decolourization ability in the range of pH from 4 to 9, temperature from 30 °C to 42 °C...

In this study, CN-TiO₂ was modified with cryptomelane octahedral molecular sieves (OMS-2) by the sol-gel method based on the self-assembly technique to enhance its photocatalytic activity under the daylight irradiation. The synthesized samples were characterized by X-ray diffraction (XRD), UV-vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR) and porosimeter analysis. The results...
