Heating rate and temperature effects on the BaTiO3 formation by thermal decomposition of (Ba,Ti) organic precursors during the Pechini process
(2008-01-15)
Different thermal treatments for the synthesis of BaTiO3 powder obtained through the Pechini method were studied. The synthesis of BaTiO3 starts at 150 °C by the thermal dehydration of organic precursors. The usual inevitable ...
Spectroscopic and thermal characterization in poly(p-phenylene vinylene)/sol-gel silica sample
(Elsevier B.V., 2003-12-01)
The absorption and luminescence spectra for the poly(p-phenylene vinylene)/sol-gel silica with different thermal treatments were measured. A considerable increase in the luminescence was observed for the polymer introduced ...
Hydrothermal treatment of gadolinium oxide in presence of silica
(1994-12-01)
Hydrothermal and solvothermal (isopropanol) treatments of gadolinium oxide and silica were investigated under different pressure and temperature conditions. Products were examined by infrared vibrational spectroscopy (IR), ...
EFFECTS OF THERMAL TREATMENT ON THE PHYSICOCHEMICAL CHARACTERISTICS OF GIANT BAMBOO
(UNIV FEDERAL LAVRAS-UFLA, 2011)
Despite countless use possibilities for bamboo, this material has two major disadvantages. One drawback is the low natural durability of most bamboo species due to presence of starch in their parenchyma cells. The other ...
Thermal treatment of soils contaminated with gas oil: Influence of soil composition and treatment temperature
(Elsevier Science, 2002-10)
Samples of two soils containing different organic matter contents, neat or contaminated with gas oil (diesel fuel oil) at 2.5wt.% were heated from room temperature to different final temperatures (200-900°C). The experiments, ...
Thermal characterization of anaerobic sludges from wastewater treatments applied to biological generation of H2
(2017-02-01)
A wide variety of organic residues may be used as energy source such as anaerobic sludge from wastewater treatment systems. However, due to inherent differences in composition, the proper characterization of these biomasses ...
Influence of the thermal treatment in the crystallization of NiWO4 and ZnWO4
(Springer, 2009-07-01)
NiWO4 and ZnWO4 were synthesized by the polymeric precursor method at low temperatures with zinc or nickel carbonate as secondary phase. The materials were characterized by thermal analysis (TG/DTA), infrared spectroscopy, ...
POST-THERMAL TREATMENT OF ORIENTED STRANDBOARD (OSB) MADE FROM CYPRESS (CUPRESSUS GLAUCA LAM.)
(Universidad del Bío-Bío, 2007)
The influence of thermal treatment on the preparation of PNM and PMN-PT thin films
(Elsevier B.V., 2003-03-01)
Ferroelectric thin films belong to a class of materials with great technological importance in optic fibers, micro-electromechanical systems, and microprocessors and computers memories.The (1-x)PbMg1/3Nb2/3O3(x)PbTiO3 ...
Nutritional composition, phenolic compounds, nitrate content in eatable vegetables obtained by conventional and certified organic grown culture subject to thermal treatment
(Wiley-Blackwell Publishing, Inc, 2009-06-01)
The aim of this work was to analyse some nutritional characteristics in eatable vegetables obtained by conventional and organic grown culture, focusing on vegetable parts that are generally rejected by consumers. Samples ...
