    Comparison Of Different Life Stages Of Total, Phospholipid And Triacylglycerol Fatty Acids Of Lucilia Sericata
    (ABADER (Adıyaman Bilimsel Arastırmalar Dernegi), 2021) Kizmaz, V.
    Lucilia sericata, which belongs to the Calliphoridae family (Diptera), is used as a debridement tool in open necrotic wounds that do not respond to conventional treatments. Knowing the total, phospholipid (PL), and triacylglycerol (TAG) fatty acid content of L. sericata fly, which is important for health, in its different stages is important both in terms of taxonomy and physiology. After L. sericata samples used in the study were obtained commercially, they were bred under laboratory conditions and then the fatty acids in different stages were analyzed by gas chromatography. Sixteen fatty acids are determined as a result of the analysis. When individual fatty acids are considered, Palmitic acid (16:0), Palmitoleic Acid (16:1n-7), oleic acid (18:1n-9) and Linoleic Acid (18:2n-6) were found to be major ones, while the others are detected in trace amounts. It is determined that, out of total, PL and TAG, saturated fatty acids (SFA) are found at a high percentage in the eggs, monounsaturated fatty acids (MUFA) are the highest in the larvae, and polyunsaturated fatty acids (PUFA) are the highest in fly and pupa. Furthermore, out of total, PL and TAG, ∑PUFA is at a low percentage in the egg and the larval stages. Different results are found at different stages in this study. This may be because fatty acid percentages that change during metamorphosis meet different physiological needs at different phases. © 2021, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi).

    Synthesis and Characterization of Boron Nitride Nanotubes (Bnnts) With a New Method and Precursor Materials
    (Gumushane University, 2021) Tarhan, T.
    Boron nitride nanotubes (BNNTs) have many application areas thanks to their superior properties such as thermal and electrical insulation, resistance to oxidation, high hydrophobicity, and high hydrogen storage capacity, as well as biocompatible properties. Therefore, new synthesis methods are being searched for BNNT with increasing interest in recent years. In this study, high purity and yield BNNTs were synthesized using precursor materials and methods that were not previously tried in the literature. A chemical vapor storage (CVD) furnace was used for the synthesis, and various parameters were changed to achieve optimum conditions. The structure of the obtained BNNTs was characterized by Fourier conversion infrared spectroscopy (FTIR), Raman spectroscopy, and a UV-visible spectrophotometer. In addition, surface morphologies were illuminated using transmission electron microscopy (TEM) and scanning electron microscopy (SEM). However, it has been observed that BNNTs obtained as a result of HR-TEM (high-resolution transmission electron microscope) analysis have a single-walled structure that is difficult to synthesize. This increases the importance and quality of synthesized BNNTs. © 2021, Gumushane University. All rights reserved.
