Thermal decomposition of some diuretic agents
(1996-05-01)
Thermogravimetry-derivative thermogravimetry and differential scanning calorimetry were used to study the thermal behaviour of furosemide, hydrochlorothiazide, spironolactone, and amiloride hydrochloride. The results ...
Crystal structures and thermal behavior of alkaline earth tricyanomethanides
(VERLAG Z NATURFORSCH, 2008)
The alkaline earth tricyanomethanides Mg(tcm)(2) center dot 2H(2)O, Ca(tcm)(2), Sr(tcm)(2) - H2O and Ba(tcm)(2) center dot 2H(2)O were prepared from aqueous solutions of the respective chlorides and silver tricyanomethanide. ...
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), ...
Automatic system for thermal damage detection in manufacturing process with Internet monitoring
(2006-07-17)
This work involved the development of a smart system dedicated to surface burning detection in the grinding process through constant monitoring of the process by acoustic emission and electrical power signals. A program ...
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 ...
Investigation of temperature influence on photo-induced conductivity in n-type AlxGa1-xAs
(1998-12-01)
We present conductance as function of temperature (G×T) under influence of monochromatic light in the range 0.5-1.5 μm for direct as well as indirect bandgap n-type AlxGa1-xAs. Results obtained below 60 K in indirect bandgap ...
Ceramic coating for refractories protection against carbon oxidation, Part 1: Protection mechanisms
(1999-03-01)
For retarding carbon oxidation in refractories during the preheating of metallurgical furnaces, a ceramic coating, made mainly of sodium phosphosilicate and clay was developed. The coating presents high adherence to the ...
Direct amorphous-to-cubic perovskite phase transformation for lead titanate
(2000-01-01)
The phase evolution of lead titanate processed by the polymeric precursor method was investigated by thermal analysis, X-ray diffraction, and high-resolution transmission electron microscopy. The results showed that the ...
In(PO3)3 stabilised fluoroindate glasses
(1998-07-24)
Results on thermal and optical characterization of new lanthanide containing fluoroindate glasses in the system InF3-BaF2-In(PO3)3 are presented. Good optical quality and very stable glasses presenting up to 5 mm in thickness ...
Sand-water slurry erosion of API 5L X65 pipe steel as quenched from intercritical temperature
(2000-12-01)
The objective of this study was to analyze the erosion of API 5L X65 pipe steel whose microstructure consisted of ferrite and martensite obtained by quenching from intercritical temperature (770 °C). Jet impingement tests ...
