Effects of thermal treatment on phase transitions and on the mechanical relaxation in poly(vinylidene fluoride)
This work reports on the effects from thermal treatment in poly(vinylidene fluoride), PVDF, obtained with differential scanning calorimetry (DSC) and dynamic thermal analysis (DMA) measurements. It is shown that in successive ...
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 behavior of residues (sludge) originated from Araraquara water and sewage treatment station
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. ...
Applying GIS tools for analysing urban thermal environment
A methodology for analyzing the solar access and its influence on both air temperature and thermal comfort of the urban environment was here developed by applying the potentiality of GIS tools. Urban canyons in a specific ...
Calcium polyphosphate coacervates: effects of thermal treatment
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)
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 ...

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 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 ...
