nanostructured iron oxide powder that has been recovered from waste pickling liquor unit of steel industry was studied for oxidation catalytic applications. in this research, the powder was characterized by x-ray diffraction (xrd) and transition electron microscopy (tem) for determination of phase structure, morphology and particle size. furthermore, the specific surface area of the powder was ...

a facile co-precipitation method for the synthesis of well-dispersed ndfeo3 nanocrystals is developed in the presence of octanoic acid as surfactant. co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. the product is characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microsc...

Multiphase waterborne polymer particles provide advantages in more demanding applications, and their performance depends on particle morphology. Currently, no dynamic model for the prediction of the development of the morphology of multiphase latex particles is available. In this work, a model was developed for the prediction of the dynamic development of the morphology of multiphase waterborne...

nano-hydroxyapatite/gelatin (nha/ge) microspheres are currently used in bone tissue engineering as bone filler. in this  study, the effect of fabrication process parameters on the particle size of nano-hydroxyapatite/gelatinmicrospheres was investigated. the nha/ge microspheres were fabricated using water in oil emulsion. in order to design an experimental design, a surface response model with ...

in this study the characteristics of two different kinds of la0.6sr0.4co0.2fe0.8o3 (lscf) powders, one in-house synthesized powder by a co-precipitation method and another one purchased from fuel cell materials co. (fcm co., usa), were compared. the co-precipitated powder was prepared by using ammonium carbonate as precipitant with a nh4+/no3- molar ratio of 2 and calcination at 1000c for 1 h....

Nano-sized titanium dioxide TiO2 powder was prepared by new wet chemical route from its precursor Titanium (IV) chloride (TiCl4) as precursor with isopropoxy alcohol in presence of nitric acid under ambient condition. Their morphologies, phase compositions and components of the TiO2 nanoparticles were characterized by transmission electron ...

Article history: Received 29 October 2015 Received in revised form 18 December 2015 Accepted 19 December 2015 Available online 29 December 2015 Particle shape plays an important role in determining the engineering behaviour of granular materials. In this regard, characterisation and quantification of particle shape are essential for understanding the behaviour of granular materials. X-ray micro...

Mucoadhesive chitosan microspheres of amlodipine besylate were prepared for nasal administration with the aim of avoiding the first pass effect. A series of batches of microspheres were prepared by simple emulsification crosslinking method to optimize parameters like external phase (mixture of heavy and light liquid paraffin in the ratio of 1:1), stirring rate (1200 rpm), dioctyl sodium sulfosu...

Asymmetric nanocomposite particle pairs of polystyrene and silica were prepared via one-step miniemulsion polymerization for the first time. The transmission electron microscopy images showed that these nanocomposite particle pairs were monodisperse and highly asymmetric in morphology. The key to obtaining the asymmetric nanocomposite particle pairs was the combination of miniemulsion polymeriz...
