Three perchlorate salts of pyridine have been prepared and characterized by gravimetric and elemental analyses. Thermogravimetry (TG) and differential thermal analysis (DTA) have been carried out in static air, to examine the thermal decomposition process of these salts. Isothermal TG of these salts have been done to evaluate the kinetics of thermal decomposition in the temperature range 290-41...

A complex of Cu(II) with 1-(6-HydroxyNaphthalen-2-yl) Butane-1,3-Dione (HNBD) was synthesized and characterized by elemental analysis, IR, UV and DTA-TG-DTG techniques.    IR spectra as well as UV-visible absorption measurements indicated that Cu(II) ion was coordinated to the HNBD ligand. The TG-DTA-DTG curves showed that thermal decomposition o...

The thermal decomposition behavior of olive hydroxytyrosol (HT) was first studied using thermogravimetry (TG). Cracked chemical bond and evolved gas analysis during the thermal decomposition process of HT were also investigated using thermogravimetry coupled with infrared spectroscopy (TG-FTIR). Thermogravimetry-Differential thermogravimetry (TG-DTG) curves revealed that the thermal decompositi...

in this research, cuo spherical-like nanoparticles were synthesized using the planetary ball mill method. the structure, particle size and morphology of the resulting cuo nanoparticles were characterized by xrd (x-ray diffraction), sem (scanning electron microscopy) and saxs (small-angle x-ray scattering) methods. the results of this investigation showed that the smallest particles which were o...

magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. the most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (mri) and heating mediators for cancer therapy. in...

in this paper, cubic nickel oxide nanoparticles were successfully prepared by solid-state thermal decomposition of nickel(ii) macrocyclic schiff-base complex at 450°c for 3 h without employing toxic solvent or surfactant and complicated equipment. nickel(ii) macrocyclic schiff-base complex was synthesized by the reaction of 1,2-bis(2-formyl-3-methoxyphenyl)propane, nicl2•6h2o and 1,3-phenylened...

in this paper, macrocyclic cobalt(ii) complexes [col1](no3)2.4h2o (1) and [col2](no3)2.2h2o (2) have been synthesized from the reaction of dialdehydes 1,2-bis(2-formylphenyl)ethane and 1,3-bis(2-formylphenyl)propane, co(no3)2.6h2o and 1,2-cyclohexanediamine with molar ration 1:1:1 in methanole and characterized by elemental analyses and ft-ir spectroscopy. then used as precursors for preparatio...

in the current study, synthesis and characterization of a new nano-structured zirconium(iv)-minoxidil complex (1), where minoxidil, (c9h15n5o; 6-(1-piperidinyl)-2,4-pyrimidinediamine 3-oxide), have been investigated in two different solvents. the compound 1 has been synthesized by sonochemical method in the presence of methanol and monoethylene glycol (meg) as solvents and characterized by scan...
