    Aerobic oxidation of alcohols catalyzed by an efficient heterogeneous mixed metal hydroxide catalyst
    (2024-08) Bilgin, Suay
    Aerobic alcohol oxidation is one of the important reactions of organic chemistry used both in academic research and in many industries such as medicine, cosmetics and food. Aldehydes, carboxylic acids and ketones resulting from alcohol oxidation are encountered as intermediates or final products. However, some oxidation methods developed to date have drawbacks such as expensiveness, being hazardous to human health and the environment, and having low sustainability. For this reason, Fe0.6Mn0.4(OH)x mixed metal hydroxide catalyst was developed in a collaborative work by the Ozensoy and Türkmen research groups by avoiding these drawbacks and was first used in the C-H activation reaction giving successful results. In this project, alcohol oxidation reactions were carried out using the same catalyst. Optimized reaction conditions were found by the model reaction of conversion from benzhydrol to benzophenone. Then, substrates with different electron withdrawing and donating groups attached to benzhydrol were tested along with benzyl alcohol and 1-phenylethanol derivatives. Finally, an attempt was made to obtain information about the working mechanism of the catalyst by performing a kinetic isotope effect experiment and various control experiments.

    Türkiye'de Bahailik ve Bahai kültürü
    (Bilkent University, 2019) Bilgin, Suay; Güzel, Furkan; Akyön, Burak; Kocaman, Arda; Laçin, Abdussamed
    19. yüzyılın ikinci yarısında İran’da ortaya çıkan Bahai dini, peygamberi Hz. Bahaullah ve arkadaşları aracılığı ile zaman içinde tüm dünyaya yayılmıştır. Osmanlı İmparatorluğu da bulunduğu coğrafi konum itibariyle bu din ile tanışmış ve Bahai dini bu sayede toplumda kabul görmüştür. Bahai dininin Türkiye’de ve dünyada pek çok müridi bulunmaktadır. Bu çalışmada Bahai dini kültürel ögeleri, tarihi ve Bahai toplumu faaliyetleri anlatılmıştır. Bahai dini mensubu Semih Özşuca ile bir röportaj gerçekleştirilmiştir.
