Decomposition of perfluoropolyether lubricants
A study using TG–MS in the presence of alumina powder
) Conclusions • The use of high temperature isothermal TG to study the weight loss of PFPE Krytox® XHT-1000 was confirmed. • The coupling of a mass sensitive detector with the
isothermal TG and DSC curves, at 160 °C, of the four samples. It can be noticed that these results agree with the TG curves shown in Fig. 1 . Only the thermal losses related to the first TG step occurred at 160 °C for 2 h, suggesting that the toasting

recorded on a FTIR-8400S (Shimadzu Corporation, Japan) using KBr disks. DSC measurement was investigated in a nitrogen atmosphere using a Q80 DSC Apparatus (TA Corporation, America). The thermal stability of PMMA/nano-PPSQ composites was measured by non-isothermal
Thermogravimetric analysis on gasification reactivity of Hailar lignite
Influence of inherent mineral matters and external ash
from Inner Mongolia of China is taken as the initial raw material, and its gasification characteristics is investigated by non-isothermal TG, FTIR, and X-ray diffraction (XRD) methods. The main objective of the study is to investigate the catalytic

Conclusions The araça oil has high linoleic acid content, which makes it useful for human consumption. The thermal studies carried out on non-isothermal TG in nitrogen and in air provide a comparison and understanding of the araça oil behavior during
studies carried out on non-isothermal TG in N 2 and in air provide an understanding of the behavior during thermal analysis. DTA and DSC curves show that the jerivá oil has an exothermic event which corresponds to the oxidation process. Furthermore, DSC
information concerning the inorganic matter of the sludge samples. The thermal studies carried out on non-isothermal TG in N 2 and in air, provide an understanding of the thermal behavior of the organic matter. Furthermore, TG curves may be utilized to
.) The study of the isothermal TG curve of the essential oil from the fruits of Pimenta dioica (L.) was shown to be important when scent essences are used as bee baits, as the results point out the percentage of mass loss as a function of time. This
