    Nonlinear Inorganic Optical Materials
    (Ege Üniversitesi, 1999) Topaloğlu, Işıl
    Ticari olarak uygulamaları bulunan nonlinear optik materyallerin geliştirilmesi için yapılmakta olan çalışmalar özellikle 1980 yılından sonra artış göstermiştir. Bu amaçla incelenen sistemler arasında inorganik kristaller, yarı iletkenler, organometalik bileşikler, organik kristalin monomerler, ve delokalize $\Pi$ elektronları içeren uzun zincirli polymerler Informasyon işlemlerinde optik çevirme, telekominikasyon, optoteknoloji, ve optik frekans çevirme amaçlı olarak çok yaygın olarak kullanılmaktadır. Bu derleme makalesinde nonlinear optik özellik gösteren inorganik bileşikler hakkında kısa bilgi verilmiştir.

    A Research on the Production of Silk Sericin Powders by Using Spray Drying Method
    (Ege Üniversitesi, 2009) Genç, Gözde; Bayraktar, Oğuz; Başal, Güldemet
    Sericin protein is usually discarded as a waste in silk industry. Production of silk sericin powders, which can be incorporated into fibers used in textile industry, by spray drying method will enable value-added utilization of waste sericin. in this study aqueous sericin solutions were used as raw material for the production of dry powders using a lab-scale spray dryer. A linear regression analyses were employed, in addition to experimental design at two levels with three factors for the analysis of three responses: moisture content, particle type and agglomeration degree. The process factors were the drying air temperature (120°C and 160°C), the feed rate (1.25x10-4 and 2.5x10-4 dms -), and the concentration of sericin solutions of 10% and 30% (w/w) fed to the spray dryer. The three responses were analyzed statistically to determine the effective parameters and it was concluded that moisture content depended on three factors-drying air temperature being the dominant parameter. Particle size and shape depended mainly on feed rate and agglomeration depended on the moisture content of the product.
