Thermal behavior of lignin and cellulose from waste composting process
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 EVOLUTION OF MICROPOROUS NITROPRUSSIDES ON THEIR DEHYDRATION PROCESS
(Journal of Thermal Analysis and Calorimetry,, 2013-01-16)
Sintering of porous alumina obtained by biotemplate fibers for low thermal conductivity applications
In this research report, a sintering process of porous ceramic materials based on Al2O3 was employed using a method where a cation precursor solution is embedded in an organic fibrous cotton matrix. For porous green bodies, ...
Photoacoustic thermal characterization of spark‐processed porous silicon
(Journal of Applied Physics, 2013-01-16)
Graphite dispersions as a basis for development of high thermal conductivity fluids
Both conductivity and thermal resistivity measurements of commercial graphite dispersions in non-aqueous polar fluids and non-polar fluids were carried out. Fluids exhibiting different densities as: mineral oil, ethylene ...
Characterization and thermal behavior of residues from industrial sugarcane processing
The increase in sugarcane production and processing in order to obtain important products such as sugar and ethanol has the negative aspect of also increasing industrial residues. The most important residues originated ...
Comparison of thermal scattering processing options for S(α,β) cards in MCNP
The MCNP distributions include sets of pre-calculated thermal scattering libraries but these libraries are available for several temperature steps only. In order to achieve reliable results it is suitable to process the ...
Thermal diffusivity of polymers by modified angstrom method
(ELSEVIER SCI LTD, 2010)
The nature of the molecular structure of plastics makes the properties of such materials markedly temperature dependent. In addition, the continuous increase in the utilization of polymeric materials in many specific ...
Evaluation of organic molecules originated during composting process
The composting process using sugarcane bagasse, animal manure, and urea as source of organic matter, microorganism, and nitrogen, respectively, were evaluated regarding the thermal behavior considering the maturation period: ...
