(Superficies y Vacio, 2013-01-16)
Sintering of porous alumina obtained by biotemplate fibers for low thermal conductivity applications
In this research report, a sintering process of porous ceramic materials based on Al2O3 was employed using a method where a cation precursor solution is embedded in an organic fibrous cotton matrix. For porous green bodies, ...
Thermal study of chalcones: Thermal decomposition of chalcone and its hydroxylated derivatives
Chalcones α-β-unsaturated ketones are found in large plant species. Synthesis of chalcones and its three analogues hydroxy group at 2′, 3′ and 4′ positions (2–4) was carried out. The studies of thermal behavior were made ...
Synthesis, characterization and thermal behaviour of light trivalent lanthanides folates on solid state
Solid state Ln(2)-L(3) compounds, where Ln stands for light trivalent lanthanides (lanthanum to gadolinium), except promethium, and L is folate (C(19)H(17)N(7)O(6)), have been synthesized. Simultaneous thermogravimetry and ...
Thermal study and characterization of nicotinates of some alkaline earth metals using TG-DSC-FTIR and DSC-system photovisual
(Elsevier B.V., 2015-03-20)
Characterization, thermal stability and thermal decomposition of alkaline earth nicotinates M (C6H5NO2)(2)center dot nH(2)O (M = Mg(II), Ca(II), Sr(II) and Ba(II)), were investigated employing simultaneous thermogravimetry ...
Thermal study of nickel(II) pyrazolyl complexes
The thermal behavior of the pyrazolyl complexes [NiCl2(HPz) 4] (1), [Ni(NCS)2(HPz)4] (2), [NiCl 2(HdmPz)4]·2H2O (3) and [Ni(NCS) 2(HdmPz)4]·2H2O (4) (HPz=pyrazole, HdmPz=3,5-dimethylpyrazole) has been studied by thermogravimetry ...
Thermal desorption of HCH: Temperature and time effects
To evaluate the effectiveness of the thermal remediation of soil decontamination, samples containing organochlorine insecticide hexachlorocyclohexane (HCH) were subjected to different temperatures depending on the exposure ...
Thermal analysis of coordination compounds. Part 3. Thermal decomposition of platinum complexes containing triphenylphosphine, triphenylarsine and triphenylstibine
(Elsevier B.V., 1995-08-01)
Studies by thermogravimetric analysis (TG) and differential thermal analysis (DTA) of the complexes [PtCl2L2] (L is PPh3, AsPh3, SbPh3), [PtLn] (n = 3, L is SbPh3; n = 4, L is PPh3, AsPh3); [(PtL3)2N2]; [(PtL3)2C2] and ...
