PURPOSE Thermal analysis (TGA, DTG and DTA) and differential scanning calorimetry (DSC) have been used to study the thermal behavior of terazosin hydrochloride (TER). METHODS Thermogravimetric analysis (TGA/DTG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC) were used to determine the thermal behavior and purity of the used drug. Thermodynamic parameters such...

The solid residue from wood-based ethanol production has a low ash content and high heating value, making it interesting for combustion applications, e.g. small-scale appliances and gas turbines. Combustion and gasification properties have been studied using thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Char combustion rate data obtained could be used in combustion s...

4-Nitrophenyl hydrazone single crystals were grown by slow evaporation of solvent method using acetone as a solvent. The grown crystals were subjected to various characterizations such as X-ray diffraction studies, UV-visible studies, thermogravimetric analysis and differential thermal analysis (TGA/DTA) and second harmonic generation (SHG). The cell parameters were calculated by using single c...

As compared with other candidate carbon sequestration technologies, mineral carbonation offers the unique advantage of permanent disposal via geologically stable and environmentally benign carbonates. The primary challenge is the development of an economically viable process. Enhancing feedstock carbonation reactivity is key. Heat activation dramatically enhances aqueous serpentine carbonation ...

A novel formulation for thick-film graphite sacrificial pastes is studied in this paper. It is composed of coarse graphite powder (grain size: 25 μm), dispersed in a vehicle consisting of polyvinyl alcohol (PVA) dissolved in a propylene glycol (PG) – glycerol (G) – water mix, which is not aggressive to thin LTCC sheets. The presented sacrificial paste has been successfully applied for fabricati...

A polymer nanocomposite was produced by ultrasonic-assisted dispersion of multiwalled carbon nanotubes (MWCNTs) in a polycarbonate matrix using p-xylene and dichloromethane as the solvents. The filler loading was varied from 1 to 3 wt % in order to examine the effect of MWCNTs on the structure and properties of the composites. The nanocomposites were characterized by DSC, DTA, TGA, UV-vis, FTIR...

Potato Micropropagation Medium (PMM) is the growth medium used for in vitro micropropagation of potato tubers. The present study was intended to assess the effect of biofield energy treatment on the physical, thermal and spectroscopic properties of PMM. The study was attained in two groups i.e. control and treated. The control group was remained as untreated, while the treated group was receive...
