Melanoidin is a compound produced by food industries and distilleries, which has negative impacts on the water environment due to high content of dissolved organic carbon dark color. Consequently, this work aims study catalytic properties multilayer graphene (MLG), molybdenum oxide (MoO2), manganese ferrite (MnFe2O4) in ozonation process remove melanoidin from solution. The results show that re...

With 10 million deaths in 2020 cancer remains one of the most challenging diseases contemporary medicine. Chemotherapy, surgery, and radiation therapy are commonly used to treat tumors. These treatments harm healthy tissues succeed rarely advance stages cancer. Recent studies indicate that magnetic hyperthermia, which involves targeted delivery nanoparticles tumor cells followed by localized re...

In the present study, heterogeneous electro-Fenton (HEF) process using MnFe2O4-GO catalyst is employed for successful removal of dye from aqueous solution. Pt coated over titanium and graphite felt were used as electrodes. The study focuses on efficiency electrodes Rhodamine B (RhB) solution application same in real textile wastewater. effect various operational parameters like pH, applied volt...

Phase-pure 6 nm spinel MnFe2O4 nanoparticles with high specific surface area of 145 m2 g−1 were successfully prepared via microwave-assisted non-aqueous sol-gel synthesis. The phase evolution during postsynthetic thermal treatment was investigated systematically by various methods, including powder X-ray diffraction (PXRD), pair distribution function (PDF) analysis, and Raman spectroscopy. Our ...

This work presents the effect of atomic substitution on MnFe2O4–Na2CO3 thermochemical cycle for H2 production. The non-oxidative decarbonation/carbonation reaction mixture is investigated as starting reference. Repeated cycling results in a 30% loss reversibility due to an overall reduction reactive interfaces. Na2CO3 Li2CO3 decreases decarbonation onset temperature by about 100 °C, but almost ...

The semiconductor spinel ferrite will have the chemical formula as AB2O4 (where A  divalent metal ion like Ni, Mn, Zn, etc and B  Iron metal ion Fe2 + and Fe3 +) and many studies have focused on the synthesis of nanomaterials because of extensive applications due to their novel properties. Magnetite and spinel ferrite nanocrystals are regarded as two of the most important inorganic nanomateri...
