Öğe 6-Hydroxyquinoline Oligomers Emit White Light(Amer Scientific Publishers, 2014) Doğan, Fatih; Bilici, Ali; Yıldırım, Mehmet; Kaya, İsmetThe 6-hyroxyquinoline (HQ) was shown to undergo an oxidative oligomerization reaction in the alkaline medium. The obtained oligo (6-hyroxyquinoline) (OHQ) was characterized with respect to chemical composition, molecular weight, particle size, thermal stability, morphology and conductivity. FT-IR and H-1-NMR spectral data suggested that the resulting product was mainly C2, C4 and C6-coupled via C-C/C-O-C linkages. OHQ emitted white light upon irradiated at 339 nm. Optical band gap (E-g) of OHQ was determined to be 2.78 eV. The isolated product was amorphous and soluble in common polar organic solvents. The solid state conductivity studies for OHQ were also performed and found to be in the region of semiconductor.Öğe A comparative study of 9,9-bis(4-aminophenyl)fluorene polymers prepared by catalytic and non-catalytic oxidative polymerisation methods(Pergamon-Elsevier Science Ltd, 2011) Bilici, Ali; Kaya, İsmet; Yıldırım, Mehmet9.9-Bis(4-aminophenyl)fluorene (APF) polymers were synthesized by two different pathways. The different synthetic routes gave polymers with different structures. FT-IR and NMR studies revealed that the catalytic oxidative polymerisation of APF in acetonitrile produced P2, whereas oxidative polymerisation of APF in aqueous alkaline media gave P3. The effects of these different techniques on spectral, thermal, optical, electrical, electrochemical, and morphological properties of resulting polymers were investigated. (C) 2011 Elsevier Ltd.

Inthat study, the findings on some physical and chemical properties of the blends prepared were alsopresented. In this study, it was aimed to investigate the thermal decomposition kinetics of these preparedblends. For this purpose, thermograms of PANSA doped LDPE blends at four different heating rates wereobtained. With the addition of PANSA into LDPE, it was observed that the initial decompositiontemperature and maximum decomposition temperature of LDPE increased. Thermal decompositionkinetics of blends were performed using the integral isoconversional methods (Kissinger, Kim-Park (KP),Tang, Kissenger-Akahira-Sunose (KAS) and Flynn-Wall-Ozawa (FWO)) in addition to differentialisoconversional method (Friedman method).

Both extracts showed very similar chemical profile by checking on TLC plates, and exhibited high scavenging activity on superoxide anion radical and DPPH radical. Due to these similarities they were combined and fractionated on a silica gel column for their constituents, and the most active three fractions in DPPH assay were purified to afford a new flavone 6'-hydroxyhypolaetin 3'-methyl ether (1) besides a group of known flavonoids apigenin, luteolin, luteolin 7-O-glucoside, quercetin, quercetagetin 3-methyl ether 7-O-glucoside, isoscutellarein 8-O-glucoside. Their structures were established by UV, UV shift reagents, and H-1 NMR spectroscopic techniques. Antioxidant activity of the new flavone was investigated by P-carotene bleaching and DPPH radical scavenging activity methods, and it showed a high activity in the first system, but not so good in the latter.

In particular, rapid and precise analysis of this type of interaction is a vital element for pharmaceutical studies. In the present study, a novel reduced graphene oxide/ palladium nanoparticles/ poly(2-amino-4-chlorophenol) (rGO/Pd@PACP) nanocomposite was synthesized by chemical process to modify pencil graphite electrode (PGE) surface. Here, the performance of the newly developed nanomaterial-based biosensor for drug-DNA interaction analysis has been demonstrated. For this purpose, it was determined whether this system, which was developed by selecting a drug molecule (Mitomycin C; MC) known to interact with DNA and a drug molecule (Acyclovir; ACY) that does not interact with DNA, performs a reliable/accurate analysis. Here, ACY was used as a negative control. Compared to bare PGE, the rGO/Pd@PACP nanomaterial modified sensor exhibited 17 times higher sensitivity performance in terms of guanine oxidation signal measured by differential pulse voltammetry (DPV). Moreover, the developed nanobiosensor system provided a highly specific determination between the anticancer drug MC and ACY by discrimination the interactions of these drugs with double-stranded DNA (dsDNA). ACY was also preferred in studies for the optimization of the new nanobiosensor developed. ACY was detected in a concentration as low as 0.0513 μM (51.3 nM) (LOD), and limit of quantification (LOQ) was 0.1711 μM with a linear range from 0.1 to 0.5 μM.Öğe Adsorption of uranium (VI) from aqueous solutions using boron nitride/polyindole composite adsorbent(John Wiley and Sons Inc, 2024) Emre, Deniz; Selçuk Zorer, Özlem; Bilici, Ali; Budak, Erhan; Yılmaz, Selehattin; Çalışkan Kılıç, Necla; Gökırmak Söğüt, EdaTurbostratic boron nitride (tBN) surface is modified with polyindole (PIn) by a facile polymerization technique and the uranyl adsorption efficiency of this mesoporous hybrid is investigated. The successful surface modification is confirmed by FT-IR, Raman, XRD, TEM, SEM, EDX, EDS mapping XPS, BET, and zeta potential techniques. The batch experiments are performed in various temperatures (T), contact times (t), pH, and initial solution concentrations (C0) to evaluate its adsorption performance. The optimum adsorption performance is achieved at pH = 5.0–5.5, T = 307 K, t = 10 min, C0 = 18 mg L−1. These experimental results are evaluated using Freundlich, Redlich–Peterson, and Langmuir isotherm models, which presents equivalent regression coefficients. Maximum adsorption capacity (qm) of the nanoadsorbent (tBN/PIn), determined by the Langmuir isotherm, is 315.29 mg g−1. The adsorption kinetics of uranyl ions on tBN/PIn are in harmony with the pseudo-second order model. tBN/PIn nanoadsorbent provides high adsorption efficiency even at exceptionally low UO22+ concentration range (4–40 mg L−1) and low adsorbent mass (0.005 g). XPS analysis results show that 0.05% of uranium is adsorbed on tBN/PIn via mainly U-O coordination. The results of present study demonstrate that tBN/PIn can a potential adsorbent for removing uranium from aqueous solutions.Öğe Arginine-functionalized graphene quantum dots@palladium composite modified pencil graphite electrode for electrochemical detection of DNA-mitomycin C interaction(Elsevier Ltd, 2025) Denizhan, Nuray; Yilmaz, Selehattin; Ozkan-Ariksoysal, Dilsat; Emre, Deniz; Bilici, AliIn the present study, modified pencil graphite electrodes were prepared by synthesizing a novel nanocomposite with palladium and arginine-functionalized graphene quantum dots (Arg@GQDs) for the electrochemical monitoring of anticancer compound mitomycin C (MC) and double-stranded DNA (dsDNA) interaction for the first time. The oxidation responses of both guanine in DNA and the MC drug were measured in the same potential scanning range, and the drug-DNA interaction was determined by the differential pulse voltammetry (DPV) method. To improve the performance of the developed system, experimental parameters such as dsDNA and MC concentration and their interaction times were optimized. The surfaces obtained after the modification were characterized using scanning electron microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX), Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD), Ultraviolet-Visible Spectroscopy (UV–Vis), Fourier Transform Infrared Spectroscopy (FTIR), X-ray photon spectroscopy (XPS), Thermogravimetric analysis (TGA) cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) methods. The developed nanocomposite-modified electrodes (Arg@GQD@Pd@PGEs) provided higher guanine oxidation signals than PGEs. The limit of detection (LOD) values for dsDNA immobilized on PGE and Arg@GQD@Pd@PGEs were 0.713 pg 50 μL−1 and 0.019 pg 50 μL−1, respectively. © 2025 Elsevier B.V.Öğe Ayarlanabilir ve Çoklu Renk Emisyonu Verebilen Kinolin Polimerlerin Sentezleri Ve Karakterizasyonlari(2015) Bilici, Ali; Doğan, Fatih; Özay, ÖzgürYapılan çalışmada, amino kinolin monomerlerinin farklı oksidantlar vasitasıyla oksidatif polimerizasyonları gerçekleştirildi.

The spectroscopic measurements indicate that PHCA consists of a mixture of branched and linear aniline chain units. Data from antioxidant potential assays show that PHCA exhibits moderate 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity but excellent metal ion chelating ability. The metal chelating ability of PHCA (82.14 +/- 2.39%) is about 2 times higher than that of EDTA (30.08 +/- 0.81%) at a concentration of 100 mu g/mL. In addition, as a potent antioxidant stabilizer, the influence of PHCA on the thermooxidative degradation of polypropylene (PP) is also investigated. The insertion of PHCA into PP matrix improves significantly both the oxidation induction time (OIT) and the onset oxidation temperature (OIT) of virgin PP.Öğe Biosynthesis and Characterization of Organosoluble Conjugated Poly(2-aminofluorene) with the Pyrazine Bridged(Amer Chemical Soc, 2010) Bilici, Ali; Kaya, İsmet; Yıldırım, MehmetIn this paper, the results on horseradish peroxidase (HRP)-catalyzed oxidative polymerization of amine-functionalized fluorene monomer, 2-amino fluorene (AV). are reported. The-resulting polymer exhibits an exciting molecular structure and spectral properties.
