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.

Özet

Yağ asitleri yaşam için hayati öneme sahip olan trigliserit ve fosfolipitlerin yapısında bulunur. Stearik asit, yağ asitlerinin önemli bir üyesidir. Sabun, deterjan ve lastik gibi çeşitli ürünlerin imalatında kullanılır. Stearik asidin termal ve optik karakterizasyon veri tabanını sağlamak değerlidir. Bu çalışmada, stearik asidin termogravimetrik analizi, X-ışını toz kırınımı, dağılımlı Raman ve Fourier dönüşüm kızılötesi spektroskopileri çalışılarak kapsamlı bir veri tabanı hazırlanmıştır. Stearik asidin termal bozunma sıcaklığı, X-ışını kırınım açıları ve kızılötesi titreşim modları belirlendi. Stearik asit, kadmiyum selenür kuantum noktalarının, bizmut nanoparçacıklarının ve karışık bakır/çinko nanokristallerinin sentezinde kullanılmıştır. Bu nanoyapıları sentezlemek için sıcak enjeksiyon ve tek kap sentez yöntemleri kullanılmıştır. Boyutları, dağılımları, şekilleri, elementsel bileşimleri ve kristal yapıları, geçirimli elektron mikroskopi ve enerji dağılımlı X-ışını analizi ile araştırılmıştır. Karışık bakır/çinko nanokristaller X-ışını kırınım spektroskopisi ile de incelenmiştir.
