Survey on chemical, physical, and thermal prediction behaviors for sequential chemical treatments used to obtain cellulose from Imperata Brasiliensis
(2020-01-01)
The effects of chemical treatment sequences on the chemical, physical, and mainly the thermal properties of Imperata Brasiliensis grass in the process used to obtain cellulose fibers were analyzed. The thermal properties ...
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 behavior of residues (sludge) originated from Araraquara water and sewage treatment station
(Springer, 2009-08-01)
The number of the cities with canalized water and sewage treatment stations has increased lately and consequently having in mind the great concern on environment preservation and the quality of the water used by society. ...
Calcium polyphosphate coacervates: effects of thermal treatment
(Springer, 2012-08-01)
The addition of calcium chloride eletrolyte to sodium polyphosphate solutions lead to Calcium polyphosphate coacervates. The effects of a thermal treatment were investigated with the objective to increase the relative ...
Thermal treatment effects on phase transitions in P(VDF-TrFE)
(1999-12-01)
Differential scanning calorimetry (DSC) studies were performed for 60/40 P(VDF-TrFE). The results not only confirm the importance of thermal history but also show that the samples with various configurations in terms of ...
Glycerine degradation by submerged plasma
(Iop Publishing Ltd, 2019-11-13)
Organic contaminants (for example in wastewater effluents) cause serious health and environmental problems due to their high chemical oxygen demand (COD), low biodegradability, and toxicity. Non-equilibrium and thermal ...
EFFECT OF SOIL MANAGEMENT ON THEIR THERMAL PROPERTIES
(Sociedad Chilena de la Ciencia del Suelo, 2009)
Parameters optimization of heat treatment for obtaining luminescent PZT powders
(2014)
Low crystalline PZT powder samples were successfully synthesized using polymeric precursor method and slow decomposition steps. The polymeric resin precursor was thermal treated in a muffle type oven varying the temperature ...
Comparison of thermal scattering processing options for S(α,β) cards in MCNP
(Elsevier, 2013-05)
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 treatment of superconductor thin film of the BSCCO system using domestic microwave oven
(Elsevier B.V., 2012-08-01)
In this work, we report the preparation of a superconductor thin film of the BSCCO system using a good quality powder with nominal composition Bi1.8Pb0.4Sr2CaCu2Ox which was thermally treated using a domestic microwave ...
