Combustion behaviour of coal and biomass are different due to difference in their physical and chemical properties. Thermogravimetric analysis is a useful technique to determine combustion characteristics of coal/biomass blends. This study elaborates the lab scale findings of co-combustion experiments in Thermogravimetric analyzer (TGA) [in which Differential Scanning Calorimetric (DSC) and The...

Two novel oxo-centered trinuclear compounds, [M2M′O(C3H3O2)6(H2O)3] + (M = Cr, M′ = Cr, Fe) have been synthesized. The complexes were characterized by elemental analysis, infrared and electronic spectroscopy and thermogravimetric analysis (TGA). These complexes contain unsaturated carboxylate bridging ligands that cause them to have potential scopes for polymerization in the solid state by cros...

Nano-sized ZnO particles of specific morphology were synthesized using the plant leaf extracts of Aloe vera. The structures, morphology, optical properties, surface area and thermal behavior of these fabricated ZnO nanoparticles were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Ultravioletvisible spectroscopy (UV-vis), Photoluminescence (PL)/flourescence spectro...

bismuth sulfide nano-rods and nano-flowers were synthesized via a hydrothermal reaction at a relatively low temperature. thioglycolic acid is used as sulfur source and capping agent simultaneously. bi2s3 nanostructures were then added to acrylonitrile-butadiene-styrene (abs) copolymer. the thermal stability behavior of abs filled with bismuth sulfide nano-rods were investigated by thermogravime...

With the aim to enhance interfacial adhesion of a hydrophobic polymer matrix and cellulosic fibers and fillers, chemical surface modifications with silane coupling agents are performed. Thermogravimetric analysis (TGA) could be used to determine the degree of surface functionalization. However, similar thermal properties of treated and untreated cellulose hamper a precise determination of silan...

The thermal decomposition behavior of the Fe(II), Co(II), Ni(II) and Zn(II) complexes of polydithiooxamide has been investigated by thermogravimetric analysis (TGA) at a heating rate of 20°C min-1 under nitrogen. The Coats-Redfern integral method is used to evaluate the kinetic parameters for the successive steps in the decomposition sequence observed in the TGA curves. The processes of thermal...

Three azo group-containing Schiff base ligands, namely 1-{3-[(3-hydroxypropylimino) methyl]-4-hydroxyphenylazo}-4-nitrobenzene (2a), 1-{3-[(3-hydroxypropylimino) methyl]-4-hydroxyphenylazo}-2-chloro-4-nitrobenzene (2b) and 1-{3-[(3-hydroxypropylimino) methyl]-4-hydroxyphenylazo}-4-chloro-3-nitrobenzene (2c) were prepared. The ligands were characterized by elemental analysis, FTIR spectroscopy, ...

in this paper, 4,4ʹ-bipyridinium dichloride  supported sba-15 (sba@bipy2+ 2cl-) was used for the synthesis of dihydropyrimidinones. the synthesized catalyst was characterized by ft-ir spectroscopy, scanning electron microscopy (sem), transmission electron microscopy (tem) and thermogravimetric analysis (tga). this nanocomposite was shown to be an efficient heterogeneous catalyst for the synthes...
