Transparent materials

contained 28.35 mL anhydrous ethanol, 7.25 mL deionized water and 20 mL 3 M acetic acid was slowly added into the above solution with magnetic stirring at room temperature. The prepared mixture was further hydrolyzed for 60 min with stirring until the transparent sol was obtained, which was aged for 20 h at room temperature. Thus prepared TiO2 was dried at 80 °C in an oven for 12 h and calcined for 3 h at three different temperatures: 400 °C, 500 °C, 600 °C. Synthesis of TiCh photocatalyst was…

FTIR Spectroscopic Study on Inner Membrane of Egg Shell of Chicken Gallus gallus domesticus Abstract: The paper presents FTIR analysis of inner membrane of eggshell of chicken Gallus gallus domesticus. Fresh samples of egg shells are cleaned; dried and inner membrane of the shell is separated carefully for FTIR analysis. FTIR spectrum reveals a series of bands related to fats and proteins. Calcium carbonate is the major constituent (about 90%) of the shell, but it is absent in the inner shell…
