Recently the applications of functionalized magnetic nano particles are increased in a linear fashion. This is due to the ease of synthesis and controlled growth of magnetic nano particles. In the present investigation gentamicin drug functionalized Fe3O4 nanoparticles were synthesized by co-precipitation method. Thus obtained nano hybrid was characterized by Fourier transform infrared (FTIR) s...

   A method for treating fuel oil and waste water of power plant is suggested which is including vanadium elimination through contacting with humic acid coated magnetic nano-adsorbent. The nano-adsorbent was modified with humic acid (HA) as a compound having carboxyl, hydroxyl and amin functional groups. HA/Fe3O4 nanoparticles were prepared by a co-precipitation procedure and were character...

Janus particles (JPs) are unique among the nano-/microobjects because they provide asymmetry and can thus impart drastically different chemical or physical properties. In this work, we have fabricated the magnetic halloysite nanotube (HNT)-based HNTs@Fe3O4 nanocomposite (NCs) and then anchored the Janus Au-Ni or isotropic Au nanoparticles (NPs) to the surface of external wall of sulfydryl modif...

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Ni2+ in water samples. In this paper, Dioctylphthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-DOP-ED. Flame atomi...

DOI: 10.1002/sscp.202200026 This cover picture shows the applicability of Mobil catalytic material number 4 modified magnetite nano-composites (MCM-41@Fe3O4) in magnetic solid phase extraction (MSPE). MCM-41@Fe3O4 as MSPE was first added to sample solution NSAIDs containing diclofenac, ketoprofen, and mefenamic acid. After 5 min incubation, can be separated using a field. Further, supernatant c...

The nano iron oxides have been synthesized by almost all the known wet chemical methods which include precipitation at ambient/elevated temperatures, surfactant mediation, emulsion/micro-emulsion, electro-deposition etc. Iron oxides in nano-scale have exhibited great potential for their applications as catalytic materials, wastewater treatment adsorbents, pigments, flocculants, coatings, gas se...

background: chitosan nanoparticles have become of great interest for nanomedicine, biomedical engineering and development of new therapeutic drug release systems with improved bioavailability, increased specificity and sensitivity, and reduced pharmacological toxicity. the aim of the present study is to synthesis and optimization of chitosan nanoparticles for industrial and biomedical applicati...

The Fe3O4/CeO2 magnetic photocatalyst was prepared by coating directly onto the surface of magnetic Fe3O4 particles. However a direct contact of CeO2 onto the surface of magnetic Fe3O4 particles presented unfavorable heterojunction, thus the SiO2 barrier layer between magnetic Fe3O4 and CeO2 was prepared as a core-shell stucture to reduce the negative effect by combining three steps of the hydr...

It has been reported that bacteria-mediated degradation of contaminants is a practical and innocuous wastewater treatment. In addition, iron oxide nanoparticles (NP) are wastewater remediation agents with great potentials due to their strong adsorption capacity, chemical inertness and superparamagnetism. Therefore, a combination of NPs and microbes could produce a very desirable alternative to ...

An ethylene-glycol (EG) mediated self-assembly process was firstly developed to synthesize micrometer-sized nanostructured Mg-doped Fe3O4 composite oxides to decompose hexachlorobenzene (HCB) at 300°C. The synthesized samples were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, energy dispersive X-ray spectroscopy and inductively coupled plasm...
