Morphologically controlled synthesis of ferric oxide nano/micro particles has been carried out by using solvothermal route. Structural characterization displays that the predominant morphologies are porous hollow spheres, microspheres, micro rectangular platelets, octahedral and irregular shaped particles. It is also observed that solvent has significant effect on morphology such as shape and s...

In this work, a very facile one-pot hydrothermal synthesis approach has been developed for the preparation of ultrathin magnetite nanoplates. The hydrothermal procedure was performed by aging ferrous hydroxide under anaerobic conditions, which is known as Schikorr reaction. Ethylene glycol (EG), which was introduced to the reaction as another solvent, played a critical role in the formation pro...

Composite materials made of mesoporous oxide thin films containing metallic nanoparticles are of high interest in various fields, including catalysis, biosensing and non-linear optics. We demonstrate in this work the fabrication of such composite materials containing a sub-monolayer of gold nanoparticles (GNPs) of various shapes covered with mesoporous silica thin films. Additionally, the shape...

We describe a new version of the two-stage noisedriven concurrent stereo matching (NCSM) algorithm that uses symmetric dynamic programming stereo (SDPS) to estimate image noise and build candidate volumes for placing goal surfaces. In contrast to the initial NCSM, SDPS is first applied successively in xand y-directions in order to obtain a more stable disparity map from points that coincide in ...

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Cu2+ in water samples .In this paper, Chitosan was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-CHITOSAN 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-Chitosan-ED.Flame atomic abs...

The present study synthesizes a novel adsorbent by coating Fe3O4 magnetic nanoparticles with amino functionalized mesoporous silica. The FTIR spectrums indicate that silica has been successfully coated on the surface of Fe3O4 and 3-aminopropyl tri methoxysilane compound have been grafted to the surface of silica-coated Fe3O4. The XRD analysis shows the presence of magnetite phase with cubic spi...

In the present work, magnetic zeolitehave been synthesized by insitu method using combination of iron oxide nanoparticlesFe3O4 and clinoptilolite. Fe3O4nanoparticleshave been synthesized electrochemically and then clinoptilolitewas added to solution. The Fe3O4 nanoparticles synthesized at the temperature of 90° C with applying the potential of 8V for 1800 seconds. The synthesized nanocomposite ...

SiO2 was prepared from rice husk (RH) with the assistance of cetrimonium bromide (CTAB), and CuO•Fe3O4/SiO2 composite by a simple coprecipitation method to enhance Fenton-like degradation dyes in wide pH range. mesoporous material relatively large surface area 496.4 m2/g highly relative pore volume 1.154 cm3/g. The Fe3O4 CuO particles size 20–50 nm were well dispersed composite, making tighter ...

Stimuli-sensitive hydrogels have received attention because of their potential applications in various fields. Stimuli-directed motion offers many practical applications, such as in drug delivery systems and actuators. Directed motion of asymmetric hydrogels has long been designed; however, few studies have investigated the motion control of symmetric hydrogels. We designed a pine cone scale-in...
