TL;DR: In this article, a series of novel multifunctional phosphorus-containing epoxy resins (phosphorus content 2 and 4%) were synthesized from the addition reaction of 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO) and the glycidyl ether of cresol formaldehyde novolac (functionalitya 12, C12) and then cured with 4,4 0 -diaminodiphenyl sulfone (DDS), phenol novol

TL;DR: In this article, the carbonization of cellulose with sulfuric acid impregnation was studied by thermogravimetric analysis and scanning electron microscopy, and it was shown that the mass yield of carbon after 800°C treatment in nitrogen increased to 2-3 times by adding small amounts of sulphuric acid.
Abstract: The carbonization of cellulose with sulfuric acid impregnation was studied by thermogravimetric analysis and scanning electron microscopy. The mass yield of carbon after 800°C treatment in nitrogen increased to 2–3 times by addition of small amounts of sulfuric acid. The sulfuric acid is considered to work as dehydration catalyst, thus suppressing the release of volatile organic substances. The shrinkage of the sample during carbonization was also significantly reduced by the addition of sulfuric acid.

TL;DR: In this article, the thermal degradation of sugarcane bagasse and coconut fiber presents two mass loss steps attributed to the release of humidity and to the decomposition of organic material (hemicellulose, cellulose and lignin).
Abstract: Pyrolysis of sugarcane bagasse and coconut fiber was studied by thermal analysis in order to characterize their thermal behavior and to identify their constituents by the aid of their thermogravimetric curves and to determine their heat capacity by means of DSC. The Fourier Transform Infrared Spectrum (FTIR) was used to determine the main constituents present in both residues. The thermal degradation of sugarcane bagasse and coconut fiber presents two mass loss steps attributed to the release of humidity and to the decomposition of organic material (hemicellulose, cellulose and lignin). It was expected that the results of DSC analysis were almost the same for both types of biomasses.

TL;DR: In this article, a systematic investigation on the synthesis of hydrotalcites at different pH values was performed, and the results revealed that the synthesis pH plays a crucial role on the morphology, pore structure and chemical composition of the final products.
