Water soluble derivatives of cellulose are widely used in various biomedical and biotechnological applications. Sodium carboxymethyl cellulose was insolubilized in the form of microspheres using aluminium chloride as the crosslinking agent. It was observed that, depending on the preparation medium pH, the spherical product could either be a microsphere with an ionotropic interior or a microcapsule. Various microspheres with different crosslinker, biopolymer, and drug (2',7'-dichlorofluorescein and aldicarb) contents were prepared and their structures, properties, swelling behaviour and release kinetics investigated. The release kinetics could not be described by typical Fickian or non-Fickian approaches.

Facile control of hydroxyapatite particle morphology by utilization of calcium carbonate templates at room temperature Oral, Çağatay M.; Çalışkan, Arda; Kapusuz, Derya; Ercan, Batur (Elsevier BV, 2020-09-01) Hydroxyapatite (HAp, Ca-10(PO4)(6)(OH)(2)) particles are widely used in orthopedic applications due to their chemical resemblance to the inorganic component of bone tissue. Since physical and chemical properties of HAp particles influence bone regeneration, various synthesis techniques were developed to precisely control the particle properties. However, most of these techniques required high reaction temperatures, which limited the spectrum of obtained HAp particle morphologies. In this study, ellipsoidal,...
Synthesis of calcium carbonate particles for biomedical applications Oral, Çağatay Mert; Ercan, Batur; Department of Metallurgical and Materials Engineering (2020) Calcium carbonate (CaCO3) particles have been widely used in biomedical applications owing to their biocompatibility and biodegradability. In order to effectively utilize CaCO3 particles in biomedical applications, their physical and chemical properties should be systematically controlled. However, this is a challenging task due to the presence of three different anhydrous CaCO3 polymorphs having complex crystallization behavior. In this thesis, CaCO3 particles were synthesized at distinct environments to c...
Speciation of Selenium in Supplements by High Performance Liquid Chromatography-Inductively Coupled Plasma-Mass Spectrometry BAKIRDERE, Sezgin; Volkan, Mürvet; Ataman, Osman Yavuz (2015-06-13) Anion and cation exchange high-performance liquid chromatography (HPLC) combined with inductively coupled plasma-mass spectrometry (ICP-MS) were used for speciation of selenium in supplements. All the parameters in the extraction, separation, and determination procedures were optimized. Recovery studies for the selenium species from the anion and cation exchange columns were performed and there were no analyte losses. Limits of detection for selenium(IV), selenium(VI), Se in selenomethionine, and Se in sele...
Facilitation of water management in low Pt loaded PEM fuel cell by creating hydrophobic microporous layer with PTFE, FEP and PDMS polymers: Effect of polymer and carbon amounts ÖZTÜRK, Ayşenur; FIÇICILAR, BERKER; Eroğlu, İnci; BAYRAKÇEKEN YURTCAN, Ayşe (2017-08-17) Microporous layers (MPLs) were prepared with different hydrophobic polymers to establish water management in polymer electrolyte membrane (PEM) fuel cells. Besides conventionally used polymers polytetrafluoroethylene (PTFE) and fluorinated ethylene propylene (FEP), two different molecular weights (MW) of polydimethylsiloxane (PDMS) polymer were used as hydrophobic materials in MPL. Membrane electrode assemblies (MEAs) having MPLs with low MW PDMS polymer exhibited the best fuel cell performance compared to ...
Composite polysaccharides and protein hydro-gels for controlled release applications: Formulation, characterization and release studies Özel, Barış; Öztop, Halil Mecit; Aydın, Özlem; Department of Food Engineering (2023-1-26) Hydrogels are highly hydrophilic polymer gels with macromolecular three-dimensional networks. They can swell by absorbing and retaining large amount of water without dissolving and losing their integrity. Polysaccharides and proteins are commonly used for designing hydrogels to be used in food applications. Encapsulating bioactive agents is one of the common uses of these gels. Composite gels in which one or two polymers are blended to modulate the physicochemical properties of the gels have gained interest...
