Failure analysis of a martensitic stainless steel (CA-15M) roll manufactured by centrifugal casting. Part II: Thermal stress analysis by FEA
A martensitic stainless steel (CA-15M) roll manufactured by centrifugal casting and used as a glass roller failed prematurely after six rolling campaigns. A previous fractographic investigation showed that the failure of ...
Thermal decomposition of palladium(II) pyrazolyl complexes. Part I
(Elsevier B.V., 2004-08-01)
The thermal behavior of simple and mixed pyrazolyl complexes [PdCl2(phmPz)(2)] (1),[Pd(N-3)(2)(phmPz)(2)] (2), [Pd(SCN)(2)(phmPz)(2)] (3), and [Pd(N-3)(SCN)(phmPz)(2)] (4) (phmPz: 1-phenyl-3-methylpyrazole) has been ...
Thermal analysis of prednicarbate and characterization of thermal decomposition product
In the present work, the thermal behavior of prednicarbate was studied using DSC and TG/DTG. The solid product remaining at the first decomposition step of the drug was isolated by TG, in air and N(2) atmospheres and was ...
Thermal and spectroscopic study of the lanthanide 2-aminoterephthalate compounds in the solid state
Lanthanides 2-aminoterephthalate compounds were synthetized and characterized on the basis of TG-DTA data in order to study their thermal behavior, as well as to establish hydration grade and stoichiometry, while TG/FTIR ...
Synthesis, characterization, and investigation of the thermal behavior of Cu(II) pyrazolyl complexes
This work reports the synthesis, characterization, and thermal behavior of three complexes of copper (II): [CuCl(2)(HPz)(4)] (1), [CuCl(2)(HdmPz)(4)] (2), and [CuCl(2)(HIPz)(4)] (3) (HPz = pyrazole; HdmPz = 3,5-dimethylpyrazole; ...
Synthesis, characterization and thermal study of solid mandelate of some bivalent transition metal ions in CO2 and N2 atmospheres
Solid state M-L, where M stands for bivalent transition metals (Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II)) and L is mandelate, were synthesized. Simultaneous thermogravimetry and differential scanning calorimetry, ...
Trace Level Vanadium Determination Using Thermal Lens Spectrophotometry

Thermal behaviour of corn starch granules under action of fungal alpha-amylase
Corn starch, partially hydrolyzed by fungal alpha-amylase was investigated by using thermal analysis, microscopy and X-ray diffraction. After enzymatic treatment lower degradation onset temperatures were observed. DSC ...
Estudo de metodologia analítica para a determinação do cetoconazol em formulações farmacêuticas
Ketoconazole is a synthetic broad-spectrum oral and topical antifungal drug derived from imidazole, effective in the treatment of superficial mycoses and systemic infections. In this study we have tested several methods ...
Thermal stability and thermal decomposition of sucralose
(Editora Unesp, 2009-12-01)
Several papers have been described on the thermal stability of the sweetener, C12H19Cl3O8 (Sucralose). Nevertheless no study using thermoanalytical techniques was found in the literature. Simultaneous thermogravimetry and ...
