Comparative thermal degradation of biodegradable and oxo-degradable polymeric blends used in shopping bags in Brazil Close
(2013)
In the present study, a blend of poly(butylene adipate-co-terephtalate) –
PBAT and poly(lactic acid) – PLA used for biodegradable shopping plastic bags
was investigated, together with control samples of polyethylene ...
Thermogravimetric investigations during the synthesis of silica-based MCM-41
(Kluwer Academic Publ, 2001-01-01)
MCM-41 material was synthesized starting from hydrogel containing colloidal fumed silica, sodium silicate, cetyltetramethylammonium bromide (CTMABr) as surfactant, and distilled water as solvent. These reactants were mixed ...
Ilustração da influência da razão de aquecimento nos resultados de termogravimetria
(Sociedade Brasileira de Química, 2000-02-01)
The effects of the heating rate on a TG curve of a sample have been widely discussed in the literature. This paper shows the influence of heating rate (beta) in thermogravimetry results when stoichiometry determinations ...
Preparacao, caracterizacao e estudo do comportamento termico dos sele-natos duplos de calcio, berilio e amonio
(Editora Unesp, 1996-01-01)
The preparation and thermal decomposition ammonium selenate and calcium and beryllium selenates have been reported previously. However, there are not any information in the literature concerning the thermal decomposition ...
Estudo comparativo entre alguns benzalpiruvatos-fenil substituído de lantanídeos e ítrio no estado sólido.
(Editora Unesp, 1999-01-01)
In the present work, the thermal decomposition step of some lanthanides and yttrium compounds involving different ligand phenyl-substituted derivatives of benzylidenepyruvate was appraised by thermogravimetry (TG). A ...

Thermal analysis and electrochemical study of Hg reactions on Pt-30% Ir alloy electrode
(Springer, 2006-11-01)
Thermogravimetry (TG), cyclic voltammetry (CV) and other analytical techniques were used to study the reactions of mercury with Pt-30% Ir alloy. The results allowed to suggest that an electrodeposited mercury film interacts ...
Isoconversional kinetics of vaporization of nanoconfined liquids
(Elsevier B.V., 2021-04-01)
Isoconversional kinetic analysis is applied to thermogravimetry data on vaporization of n-decane and dimethyl sulfoxide from alumina nanopores and bulk. For bulk vaporization, the isoconversional activation energy is ...
