Abstract:
In this study, MgFe2O4is produced by the chemical coprecipitation method and supported by activated charcoal (C/MgFe2O4). It is observed by the FT-IR spectra and the true density. The dyeing wastewater modeled by dye Reactive Brilliant Red X-3B solution is dealt with H2O2on the radiation of microwave and used the C/MgFe2O4as adsorbent and catalyst. Tests are designed by the response surface methodology (RSM) to annalyze and optimize the process. The optimum condition is: 3 gram of C/MgFe2O4, the pH of 5, 1.1mL H202, the microwave power of 150W. The results say that C/MgFe2O4is very good on cat

The development of highly active catalysts for the pyrolysis of ammonium perchlorate (AP) is of considerable importance for AP-based composite solid propellant. In the present study, we produced porous MgFe2O4 architectures by using a facile two-step strategy.

Abstract:
The adsorption behaviour and electronic properties of ethanol vapour on MgFe2O4 ceramic nanostructures are studied using density functional theory technique. The structural stability of MgFe2O4 nanostructure is determined with the help of formation energy. The adsorption behaviour of ethanol molecules on MgFe2O4 base material is analysed in terms of average energy gap variation, Mulliken charge transfer, band gap and adsorption energy. The most prominent adsorption sites of ethanol vapours on MgFe2O4 nanostructure are investigated at atomistic level. The density of states spectrum reveals the

MgFe2O4, ZnO and MgFe2O4-ZnO samples were successfully prepared through low temperature solution combustion route. The structural and morphological investigation were accomplished by PXRD, HRSEM, UV-visible and FTIR. The PXRD results point towards the reduced size of synthesized nanocomposites, which was further confirmed by HRSEM studies. Optical properties of the prepared samples were examined by UV-visible spectroscopy. The band gap seems to be widened for prepared nanocomposites compared to pure MgFe2O4.

Abstract:
Methylene blue (MB) dye is a common colorant used in numerous industries, particularly the textile industry. When methylene blue is discharged into water bodies without being properly treated, it may seriously damage aquatic and human life. As a result, a variety of methods have been established to remove dyes from aqueous systems. Thanks to their distinguishing features e.g., rapid responsiveness, cost-effectiveness, potential selectivity, portability, and simplicity, the electrochemical methods provided promising techniques. Considering these aspects, a novel quartz crystal microbalance nano

This study proposes a synergistic treatment method for BOF slag and copper slag via oxidation–magnetic separation, with the dual goals of preparing MgFe2O4 magnetic material and stabilizing the non-magnetic slag. The effects of copper slag addition, the oxidation temperature and the oxidation time on the phase transformation and MgFe2O4 morphology during the oxidation process are investigated. The results show that copper slag addition can release the simple iron oxides of FeO and Fe2O3 from iron-containing phases from BOF slag and copper slag, promoting the synthesis of MgFe2O4.

Thermoelectric phenomena like the Seebeck and Peltier effects are known for more than two centuries with a wide range of applications. In 2008 Uchida et al. first demonstrated the phenomena called Spin Seebeck Effect (SSE) in which spin currents are generated in a ferromagnetic (FM) material in the presence of a magnetic field with an applied temperature gradient. These spin currents were electrically detected in an adjoining heavy metal layer (usually Pt) employing the Inverse Spin Hall effect (ISHE).
