The main aim of this study was the modification of jute fibres with stearic acid using new route called azide method. The surface changes after modification process were characterized by attenuated total reflectance - Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and scanning electron microscopy analyses. It was shown that the stearic acid was bonded to JF using azide method and the surface modification through azide method did not deteriorate the surface properties of JF. Representative JF containing low-density polyethylene-based composites were also prepared and characterized by tensile testing, dynamical mechanical analysis and differential scanning calorimeter. According to mechanical test results, the tensile strength and elastic modulus were increased using stearic acid modified JF through azide method. According to differential scanning calorimeter results, surface modification with stearoyl azide reduced the degree of crystallinity with respect to alkaline treated one.

Optimising clarification of carrot juice by bacterial crude pectinase Uzuner, Sibel; Çekmecelioğlu, Deniz (2015-12-01) This study was undertaken to search for potential use of crude bacterial pectinase enzyme produced from Bacillus subtilis grown on hazelnut shell hydrolysate in clarification of carrot juice and to optimize the enzyme load, pH and time using the Box-Behnken response surface methodology (RSM). The carrot juice was treated with the crude pectinase enzyme (5.60 U mL(-1)) at different concentrations (0.1-0.5%), pH (4-7), and time (2-6 h). The obtained enzyme was also compared with commercial fungal pectinase at...
Optimization and Comparison of High-Pressure-Assisted Extraction of Phenolic Compounds from Olive Pomace Okur, İlhami; Öztop, Halil Mecit; Alpas, Hami (2022-12-16) In this study, it was aimed to find the optimum condition for extraction of phenolic compounds from olive pomace by using high-pressure-assisted extraction (HPAE). In this method, different pressure parameters (300-500 MPa), times (5-15 min), and ethanol concentrations (50-90% v/v) were used. According to Box-Behnken design, 15 experimental runs were performed to find the optimum condition of total phenolic and oleuropein contents. Also, the optimum HPAE condition was compared with that of classical solvent...
A new method for synthesis of aziridine 2-phosphonates and their biological activities Babiz, Hakan; Doğan, Özdemir; Department of Chemistry (2010) A systematic study was carried out for the synthesis of aziridine 2-phosphonates by using two methods. First method is the classical Gabriel-Cromwell reaction and the second one is the modified version of Gabriel-Cromwell reaction which was developed in this thesis. In the first method, vinyl phosphonate was used as the starting material, then it was brominated to get 1,2-dibromoethyl phosphonate. HBr elimination from this compound, then reaction with different primary amines gave desired aziridinyl phospho...
DEVELOPMENT OF 3D PRINTED PECTIN AND GELATIN BASED BIOACTIVE SKIN GRAFTS Bostancı, Nazlı Seray; Tezcaner, Ayşen; Hasırcı, Nesrin; Department of Biotechnology (2021-8-10) The aim of this study was to develop an easily applicable and bioactive skin graft composed of methacrylated pectin (PeMA) and methacrylated gelatin (GelMA), containing curcumin and/or Vitamin-C as antimicrobial and healing accelerating agents, respectively. Grafts were prepared in slab, 3D printed and 3D bioprinted forms and different properties were evaluated. Preparation parameters were optimized using slabs having different compositions (PeMA:GelMA as P:G 1:1, 1:2 and 1:3, v/v). P1:G1 solution did not h...
Enantioselective chemoenzymatic synthesis of oseltamivir (tamiflu)(r) intermediates Eşiyok, Hacı; Demir, Ayhan Sıtkı; Department of Biotechnology (2008) The objective of this presented study was to synthesize optically active compounds considered to be key intermediates in the synthesis of Oseltamivir (Tamiflu) by performing chemical and biotechnological methods. Thereof, the carboethoxy cyclohexenone skeleton first was synthesized utilizing easily available substances. The synthesis of alpha-hydroxy ketones in enantiomerically pure form offers a great importance in the synthesis of biologically active compounds. Toward this fact, the enantioselective synth...
