Thermal gravimetric analysis

In the present work, a modified b-nickel hydroxide (b-Ni(OH)2) electrode material with CuO has been prepared using a co-precipitation method. The structure and property of the modified b-Ni(OH)2 with CuO were characterized by X-ray diffraction (XRD), Fourier Transform infra-red (FT-IR), Raman and thermal gravimetric-differential thermal analysis (TG-DTA) techniques.

PAn (polyaniline) and PAn/ZnO photocatalysts were synthesized using chemical polymerization of aniline. The structure characterization of the synthesized samples was analysed by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV-Vis spectroscopy measurements, and thermal gravimetric analysis (TGA). The photocatalytic activities of PAn and PAn/ZnO (0.

A new approach has been developed for the preparation of mixed-mode stationary phases to separate proteins. The pore surface of monolithic poly(glycidyl methacrylate-co-ethylene dimethacrylate) capillary columns was functionalized with thiols and coated with gold nanoparticles. The final mixed mode surface chemistry was formed by attaching, in a single step, alkanethiols, mercaptoalkanoic acids, and their mixtures on the free surface of attached gold nanoparticles. Use of these mixtures allowed fine tuning of the hydrophobic/hydrophilic balance.

In this study, the alkaline solutions (NaOH) with concentrations from 1M to 18M, red mud (RM) and silica fume (SF) were used as reactors in geopolymer reactions. RM contains 7.40% SiO2 and 13.65% Al2 O3 and SF has 94.50% SiO2 , but only the active oxides can participate in the geopolymer reactions. The activity of the oxides was investigated by determining the compressive strength of the samples under different curing conditions.

The production of natural latex is limited, and the related demand for terrestrial transportation has increased. The synthesis of rubber has become necessary and the resulting synthetics’ properties must be known. Thermooxidative degradation of synthetic rubbers 1,4- and 1,2-polybutadienes caused by heating the compounds at 100°C in the air, was monitored. The volatile compounds released during the degradation were identified using coupled modern physical methods, including NMR, TGA, MS, FTIR, etc.. Thermal gravimetric analysis showed that oxidation occurred for both 1,4 and 1,2-PB.

The high temperatures of fires affect the physical and chemical properties of the concrete and thus influence its mechanical properties. This paper presents the results of an experimental investigation on the compressive strength at high temperatures of high-strength fibre concretes. The influence of the high temperatures on the physical and chemical changes of the concrete was also analysed by Thermo Gravimetric Analysis/Differential Thermal Analysis (TGA/DTA), X-Ray Diffraction (XRD) and Scanning Electron Microscopy with Energy Dispersive Spectrometry (SEM/EDS).

Porous hydroxyapatite ceramic was synthesized by solid phase method using Ca(OH)2 and Ca3(PO4)2 at the temperature interval 200 - 350o C. The samples, after pelleting and sintering, were characterized by X-ray diffractometry (XRD), Fourier transform infra-red spectroscopy (FTIR), scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA). Porous structure of hydroxyapatite was obtained with the 42 – 55% porosity.
