Nanostructured Mn2Sb2O7 powders were synthesized via stoichiometric1:1 Mn:Sb molar ratio solid state reaction at different reactions temperatures for 8 h using MnSO4.H2O and Sb2O3 as raw materials. The synthesized materials were characterized by powder X-ray diffraction (PXRD) technique. Structural analyses were performed by the FullProf program employing profile matching with constant scale fa...

The methodology involves preparing polyvinyl sulfuric acid as a solid acid by simple mixing ofpolyvinyl alcohol with chlorosulfonic acid in CH2Cl2 at room temperature. The catalytic ability ofthe solid acid was investigated for the facile conversion of benzylic alcohols to the unsymmetricalethers with aliphatic alcohols in the presence of the solid acid. Results show that the solid acid isan ap...

This cover image is based on a review article titled “Exploration of Agricultural Residue Ash as Solid Green Heterogeneous Base Catalyst for Biodiesel Production”. In transesterification reactions, heterogeneous solid catalysts are currently replacing homogeneous because their ability to overcome hurdles associated with catalysts. developed from agricultural residues can be used green base cata...

A novel magnetically immobilized polyethyleneimine (PEI)fabricated by covalently anchoring on MCM-41 (MCM-41@PEI)was prepared. The synthesized catalyst was characterized by Fouriertransform infrared (FT-IR), thermogravimetric analysis (TGA), X-raypowder diffraction (XRD), scanning electron microscopy (SEM) andtransmission electron microscopy (TEM). The immobilized PEI wasshown to be an efficien...

Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in the available literature, however, contacted temperature measurement mechanisms have aroused concerns associated with the disruption of the el...
