One of the most important goals in medicinal chemistry is the development of new techniques and new heterocyclic compounds with pharmaceutical activity. The present study aimed to use a method for the synthesis of some 1,2-Dihydro-1-arylnaphtho [1,2-e] [1,3] oxazine-3-ones. The question this study tried to answer was this reaction can be performed in present of nano-Fe2O3 as an acid catalyst an...

Introduction Magnetic oxide nanomaterials, including iron oxide (Fe3O4 and γ-Fe2O3), spinel ferrites (MFe2O4; M=Mn, Zn, Cr, Ni, or Co) and hexagonal ferrite (MFe12O19, M=Ba and Sr) are attracting much attention due to their wide application potentials in advanced magnets, electronic devices, information storage, magnetic resonance imaging (MRI), and drug-delivery technology [1-6]. Hence, the sy...

α-Fe2O3 films with a layered distribution of nano and submicron particles were synthesized Ti-doped successfully. Morphology, element phase composition, electrochemical properties one-layered, multilayered, investigated. Doped multilayered hematite have higher catalytic water oxidation efficiency than both undoped films.

This work aims to define the microstructure and study mechanical properties of an Al matrix incorporated with various amounts Fe2O3 (3, 6, 9, 12 15 wt.%) a constant amount Ag at 1 wt.%. Al/Fe2O3 + hybrid nano-composite samples are manufactured using powder metallurgy. An aluminum is considered important alloy, owing its such as being lightweight, strong corrosion wear resistant, which enable it...

in the past decade, magnetic nanomaterials have attracted much attention due to their physical properties and technological applications. in this work, α-fe2o3 nanoparticles were first synthesized via a simple co-precipitation method using iron chloride hexahydrate (fecl3.6h2o) as precursor and ammonia solution as precipitator. the samples were then characterized by high resolution transmission...
