Abstract
Fatty acids are found in the structure of triglycerides and phospholipids which have vital importance for the life. Stearic acid is an important member of the fatty acids. It is used in the manufacturing of various products such as soaps, detergents, and rubbers. It is valuable to provide a thermal and optical characterization database of stearic acid. In this study, a comprehensive database has been prepared by studying thermogravimetric analysis, X-ray powder diffraction, dispersive Raman and Fourier transform infrared spectroscopies of stearic acid. Its thermal decomposition temperature, X-ray diffraction angles and infrared vibrational modes have been determined. Stearic acid has been used at the synthesis of cadmium selenide quantum dots, bismuth nanoparticles and mixed copper/zinc nanocrystals. Hot-injection and one-pot synthesis methods have been utilized to synthesize these nanostructures. Their sizes, distributions, shapes, elemental compositions, and crystalline structures have been investigated by transmission electron microscopy and energy dispersive X-ray analysis. Mixed copper/zinc nanocrystals have also been examined by X-ray diffraction spectroscopy.
