Thermal behavior of lignin and cellulose from waste composting process
(2013-01-01)
The lignin and cellulose were extracted from reference material (leaves and twigs) and food of compost at different times composting: zero (raw), 30, and 120 days. According to thermogravimetric analysis and its derivative ...

Thermal degradation of both latex and latex cast films forming membranes: combined TG/FTIR investigation
(Springer, 2008-03-01)
Latex collected from natural rubber trees forming membranes can be used as biomaterials in several fields being the temperature a key parameter. Thermogravimetry (TG) coupled to Fourier transform infrared spectroscopy ...
