Simultaneous thermogravimetry-differential scanning calorimetry (TG-DSC), differential scanning calorimetry-optical microscopy (DSC-optical microscopy), online coupled thermogravimetry-infrared spectroscopy evolved gas ...
Use of DSC in degree of conversion of dimethacrylate polymers: easier and faster than MIR technique
This work aims to determine the degree of conversion of polymers obtained using diurethane dimethacrylate (UDMA) monomer by two different techniques: differential scanning calorimetry (DSC) and Fourier transform infrared ...
Application of differential scanning calorimetry in hair samples as a possible tool in Forensic Science
(Editora Unesp, 2004-01-01)
A calorimetria Exploratória Diferencial (DSC) foi utilizada para estudar o comportamento térmico de amostras de cabelo e verificar a possibilidade de identificar um indivíduo com base nas curvas DSC de um banco de dados. ...
DSC studies on protein isolate of guava seeds Psidium guajava
Glutelin, the major protein fraction from guava seed, was obtained by fractioning as described by Osborne. The total proteins were extracted and the isolates obtained by isoelectric precipitation presented similar DSC ...
DSC studies on crystallization mechanisms of tellurite glasses
(Elsevier B.V., 2005-02-20)
The purpose of this work is to study the 20Li(2)O-80TeO(2) glass using the differential scanning calorimetry (DSC) and X-ray diffraction (XRD) techniques in order to understand the crystallization kinetics on this glass ...
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 ...
Investigation and characterization by TG/DTG–DTA and DSC of the fusion of Riboflavin, and its interaction with the antibiotic norfloxacin in the screening of cocrystal
This work synthesized and characterized the NOR-RIB 1:1 (mol–mol) cocrystal. During a study of the reagents, Riboflavin (RIB) melted at 304 °C, which is different from the temperature previously reported in the literature ...
Lattice enthalpy, melting enthalpy and melting temperature for adducts: Some empirical correlations by using DSC data.
(Soc Brasileira QuimicaSao PauloBrasil, 1999)
Methodology for DSC calibration in high heating rates
Despite the large use of differential scanning calorimetry (DSC) technique in advanced polymer materials characterization, the new methodology called DSC in high heating rates was developed. The heating rate during ...
Caracterização térmica (TG/DTG, DTA, DSC, DSC-fotovisual) de Hormônios bioidênticos (estriol estradiol)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciências FarmacêuticasBioanálises e Medicamentos, 2013-03-22)
Bioidentical hormones are defined as compounds that have exactly the same chemical and molecular structure as hormones that are produced in the human body. It is believed that the use of hormones may be safer and more ...
