Cation Distribution Tuning of Solution Combusted CoFe2O4 Powders

Effect of fuel content on structural and magnetic properties of solution combusted Mn0.8Zn0.2Fe2O4 powders

Single phase Mn0.8Zn0.2Fe2O4 powders were synthesized by solution combustion method. The solution combustion method relies on the exothermic self-sustained reactions in reactive solution containing of oxidizers and organic fuels. In this work, the effects of various amounts of glycine as fuel on the powder characteristics were investigated. The structure, cation distribution, microstructure, ma...

Particle Size Distribution in Food Powders

Cation distribution in natural ferrites

Mossbauer spectra of jacobsite have been recorded at temperatures of 4.2, 125, 180, 240 and 300 K and with an external magnetic field of 60 kOe applied parallel to the incident radiation at 4.2 K. The results show the presence of two different magnetic hyperfine interactions associated with the iron nuclei. Spectra of samples in external magnetic fields indicate the same sign for the magnetic h...

Synthesis and tissue distribution of CoFe2O4 Nanoparticles Coated with DMSA in rats liver

Objective(s): According to the unique properties of magnetic nanoparticles, their usages in medicine and industry have increased in the last decade. Due to the vital role of liver in the body, the accumulation of CoFe2O4 and CoFe2O4@DMSA was studied. Materials and Methods:The nanoparticles were synthesized by co-precipitation method and were coated with DMSA. The techniques XRD, TEM, DLS, FTIR,...

The effect of fuel type on the synthesis of LiMn1.5Ni0.5O4 powders by solution combustion route

In this research LiMn1.5Ni0.5O4 nano powders that are used as cathode material for lithium-ion batteries were prepared by solution combustion synthesis route. Cetyl trimethyl ammonium bromide (CTAB), mixture of “CTAB and glycine” and also mixture of “CTAB and citric acid” were used as fuel using fuel to oxidant ratio of 0.5. The effect of fuel type on microstructure and electrochemical properti...

Tuning the breathing behaviour of MIL-53 by cation mixing.

A mixed cation MIL-53(Cr-Fe) MOF has been obtained by direct synthesis. Multiple experimental techniques have demonstrated the presence of a genuine mixed phase, leading to a breathing behaviour different from either of the single cation analogues.
