Iron oxides are widely used as catalysts for photo-Fenton-like processes dye oxidation. In this study, we report on the synthesis of an α/γ-Fe2O3 mixed-phase catalyst with magnetic properties efficient separation. The was synthesized using glycine–nitrate precursors. samples were characterized scanning electron microscopy, X-ray diffraction spectroscopy (XRD), Raman shift spectroscopy, photoele...

The objective of this study was to evaluate phenolic compounds produced from the catalytic pyrolysis of pine sawdust by commercial catalysts. Eight types of commercial catalysts consisting of SiO2, montmorillonite, α-Fe2O3, HZSM-5 (Si:Al = 25:1), ZnO, γ-Fe2O3, HZSM-5 (Si:Al = 50:1), and nanoHZSM-5 (Si:Al = 50:1) were screened in a fixed bed reactor at a reaction temperature of 500 °C and a vapo...

Neocuproine has been covalently bound to silica-coated maghemite (γ-Fe2O3) magnetic nanoparticles (MNPs) by a phenyl ether linkage. The resulting MNPs are able to remove Cu(II) from 12 ppm aqueous solution with an extraction efficiency of up to 99% at pH 2.

The magnetization relaxation rate of small γ−Fe2O3 particles dispersed in a silica matrix has been measured from 60 mK to 5 K. It shows a minimum around 150 mK, that can be discussed in terms of either thermal or quantum relaxation regime.

We present a microfluidic platform that allows undergoing different chemical operations in a nanoliter droplet starting from the colloidal suspension of magnetic iron oxide (γ-Fe2O3) nanoparticles "NPs" (ferrofluid). These operations include: mixing, flocculation, magnetic decantation, colloidal redispersion, washing, surface functionalization, heating and colloidal assembly. To prove the platf...

A novel bone-targeted delivery systems based on nanocapsules was developed utilizing a Zeolitic Imidazolate Framework (ZIF-8) as a template and catechol-modified gelatin as wall material. A targeting ligand was facilely conjugated on the surface of nanocapsules. Simvastatin was encapsulated within the nanocapsules with a loading of 37.9%. Hydroxyapatite binding and in vivo biodistribution of th...

Objective: To construct carcinoma vascular endothelial-targeted polymeric nanomicelles with high magnetic resonance imaging (MRI) sensitivity and to evaluate their biological safety and in vitro tumor-targeting effect, and to monitor their feasibility using clinical MRI scanner. Method: Amphiphilic block copolymer, poly(ethylene glycol)-b-poly(ε-caprolactone) (PEG-PCL) was synthesized via the r...
