Effects of natural hard shell particles on physical, chemical, mechanical and thermal properties of composites
Çelik, Yahya Hışman; Çelik, Kadir Serdar; Kılıçkap, Erol (SAGE Journals, 2021-05-31)Shelled herbal foods are widely consumed. The evaluation of the shells of these foods is important due to their features such as low cost, ease of recycling and environmental friendliness. In this study, hazelnut shell ... -
HPLC separation of different groups of small polar compounds on a novel amide-embedded stationary phase
Aral, Hayriye; Aral, Tarık; Çelik, Kadir Serdar; Ziyadanoğulları, Berrin; Ziyadanoğulları, Recep (Elsevier, 2014-05-10)Retention behaviors of an amide-embedded silica base stationary phase, which was recently developed by our group, were studied by using six different groups of small polar compounds including phenolic compounds, substituted ... -
Polar HPLC sabit fazlarında son gelişmeler: Mixed-Mode kromatografi
Aral, Tarık; Aral, Hayriye; Altındağ, Ramazan; Çelik, Kadir Serdar (Hitit Üniversitesi, 2017-09)Sabit faz kromatografinin ana unsurudur. Özellikle HPLC’de sabit fazın önemi çok büyüktür. Ayırma mekanizması, ayırma selektivitesi ve kolon etkinliği dolgu maddesinin yapısına bağlıdır. Geleneksel sabit fazlar (NP ve ... -
Preparation of a novel ionic hybrid stationary phase by non-covalent functionalization of single-walled carbon nanotubes with amino-derivatized silica gel for fast HPLC separation of aromatic compounds
Aral, Hayriye; Çelik, Kadir Serdar; Aral, Tarık; Topal, Giray (Elsevier, 2016-03)Single-walled carbon nanotubes (SWCNTs) were immobilized on spherical silica gel with a 4-μm average particle size and a 60-Å average pore size. The amino-derivatized silica gel was non-covalently coated with carboxylated ... -
Synthesis, characterization and application of a novel multifunctional stationary phase for hydrophilic interaction/reversed phase mixed-mode chromatography
Aral, Tarık; Aral, Hayriye; Çelik, Kadir Serdar; Altındağ, Ramazan (Talanta, 2017-11-1)A novel multifunctional stationary phase based on silica gel was synthesised starting from L- isoleucine and 4-phenylbutylamine and evaluated as a hydrophilic interaction/reversed-phase mixed-mode stationary phase for ... -
