FTIR spectrum of composite aerogels shows that the relative intensity of silanol groups on the silica matrix have downward tendency with the addition of GO. The specific surface area had maxima with the addition of 0.01 wt% GO surface area to 578 m /g. The mechanical strength of aerogels was...
Different samples of rice husk ash (RHA) and sodium silicate were prepared and characterized using FTIR, NFTIR and XRD. The selected sample of RHA was obtained by calcination of untreated rice husk (R... Detail Performance of lime-BHA solidified plating sludge in the presence of Na2SiO3 an...
X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) were adopted to analyze the inhibition performance and mechanism of the MAT-inhibitor. Research indicates that the ...
exhibits a broad emission spectrum and is unaltered up to 30 kGy. Further, with an increase in irradiation dose (i.e. 30, 90 kGy), the intensity of the emission peak decreases suddenly, indicating the luminescence quenching. This is due to the formation of more defects and NBOs, which ac...
The interaction mechanism of sodium diisobutyl dithiophosphinate (DTPINa) with chalcopyrite, pyrite, galena and sphalerite was investigated by single mineral flotation experiment, adsorption measurement and FTIR spectrum analysis. Single mineral flotation experiments showed that sodium diisobutyl dithiophosphinate...
The application of FTIR, DSC, XRPD, and NMR analysis is discussed herein with respect to the interaction of Na silicate with starch in relation to gelatinization. XRPD results indicate that Na silicate, in the ionized form, disrupts the molecular structure of starch in a manner similar to ...
Therefore, the microporosity of this tubular silicate layered silicate, TSLS complex was restricted to the internal tube channels.; The focus of this work was concerted catalyst design. Modification of the external surfaces of imogolite was investigated as a possible route for enhancement of the ...
