Effects of annealing on structural and morphological properties of e-beam evaporated AgGaSe2 thin films KARAAĞAÇ, HAKAN; Parlak, Mehmet (Elsevier BV, 2009-03-15) Polycrystalline AgGaSe2 thin films were deposited by using single crystalline powder of AgGaSe2 grown by vertical Bridgman-Stockbarger technique. Post-annealing effect on the structural and morphological properties of the deposited films were studied by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDXA) measurements. XRD analysis showed that as-grown films were in amorphous structure, whereas annealing ...
Effects of pH strategy on endo- and exo-metabolome profiles and sodium potassium hydrogen ports of beta-lactamase-producing Bacillus licheniformis Ileri, N; Çalık, Pınar (Wiley, 2006-03-01) The effects of pH strategy on endo- and exo-metabolome profiling of beta-lactamase-producing Bacillus licheniformis were investigated at controlled-pH (pH(C) = 6.5, 6.75, 7.0, 7.25, 7.5) and uncontrolled-pH (pH(UC) = 7.5) values using a glucose-based defined medium. The cell concentration profiles were not affected by the pH considerably within the investigated range. The highest enzyme activities were obtained as A = 54 U cm(-3) at pHc = 6.75 among the controlled-pH operations and as A = 57 U cm(-3) at the...
Effects of spray drying temperature and additives on the stability of serine alkaline protease powders Namaldi, Aysegul; Çalık, Pınar; Uludağ, Yusuf (2006-01-01) In this study, after production by recombinant Bacillus subtilis (BGSC-1A751), carrying pHV1431:: subc gene in the complex medium and separation of solids from the fermentation broth, serine alkaline protease (SAP) was dried in order to investigate the stabilization during spray drying and subsequent storage. The effect of air inlet temperature of the spray dryer between T = 70 and 130 degrees C and the effect of protective additives, glucose and maltodextrin, at 0-2% (w/v) on SAP activity during spray dryi...
Effects of micro-nano titania contents and maleic anhydride compatibilization on the mechanical performance of polylactide CAN, ULAŞ; Kaynak, Cevdet (Wiley, 2020-02-01) The first aim of this study was to compare influences of various contents of the micro- (200 nm) and nano (50 nm)-sized titania (TiO2) particles especially on the mechanical performance of the polylactide (PLA) biopolymer. Micro- and nano-composites were prepared by twin-screw extruder melt mixing, while the specimens were shaped by compression molding. Scanning electron microscope analyses and mechanical tests revealed that due to the most efficient uniform distribution in the matrix, the best improvements...
Effects of chromic acid anodizing on fatigue behavior of 7050 T7451 aluminum alloy Ilhan, Cagri; Gürbüz, Rıza (2021-09-01) The effect of chromic acid anodizing (CAA) surface treatment on 7050 T7451 aluminum alloy was presented in this study in terms of fatigue behavior. CAA is a treatment against corrosion by producing aluminum oxide layer (Al2O3) at the surface. However, fatigue performance of 7050 T7451 is affected by the coating. In this study, eight different CAA processes were examined with regard to etching stage of pre-treatments by using an alkaline etchant and/or acid etchants with various immersion times. Optical micr...
