Article Citation - WoS: 36Citation - Scopus: 39Photocatalytic Activity of Polyaniline and Neutral Polyaniline for Degradation of Methylene Blue and Malachite Green Dyes Under Uv Light(SPRINGER, 2021-04-06) Haspulat Taymaz, Bircan; Taş, Recep; Kamış, Handan; Can, MuzafferA polyaniline (PANI) and neutral Polyaniline (NPANI) have been synthesized in acetonitrile-water mixture via the chemical oxidative polymerization of aniline. Scanning electron microscopy, FTIR spectra, UV-vis spectroscopy measurements were used to characterize the resulting PANI and NPANI. The photocatalytic activities of PANI and NPANI were investigated by the degradation of methylene blue (MB) and malachite green (MG) dyes in aqueous medium under UV light irradiation. MB and MG dyes completely degraded under UV light irradiation in the presence of NPANI after 60 and 75 min, respectively. The effect of dye type, irradiation time, dye concentration and photocatalyst amount on photocatalytic performance of PANI and NPANI have been examined under UV light irradiation. Three kinetic models have proposed for photocatalytic degradation of dyes by using PANI and NPANI under UV light illumination. This work explores the easy way to synthesize efficient PANI and NPANI polymers to degrade organic compound under both UV and visible light irradiations.Conference Object Synthesis and Characterization of Sno2 Nanoparticles With Enhanced Photocatalytic Activity(Association of Kutbilge Academicians, 2019) Orhan, Muhammet Hüseyin; Kamış, Handan; Haspulat Taymaz, BircanFor the demands of water and lack of drinkable water in our world, protecting of drinking water sources is the most important thing for mankind. But industrial wastes messes drinking waters with organic and inorganic dirtiness. Heavy metals, dyes, other toxic and non toxic wastes not only threaten aquatic ecological system but also threaten mankind with mixing clear water sources. All of these threats forces scientists to research about how to eliminate these threats. Traditional methods like adsorption, precipitation, membrane process, coagulation etc., based on transport toxins from one medium to another. Therefore, these methods inadequate for engineering because it makes secondary pollution that should be eliminated also. On the contrary, one of the advanced oxidation processes, photocatalyst; convert toxins to CO2, H2O, NOx and other non-toxin organic and inorganic compounds. The most known photocatalyst TiO2 is a low efficient photocatalyst owing to its fast recombination rate and needed high energetic photon to excite. An efficient photocatalyst should be excited easily with low energy and after excited, having slow recombination rate. In this context scientists focused on new photocatalysts. Tin dioxide (SnO2) is n-type semiconductor photocatalyst. In this work, SnO2 nanoparticles have been successfully synthesized in aqueous medium in the presence of diethylene glycol via simple chemical precipitation method for the first time. The structural, morphological and chemical characterizations were investigated by using FT-IR, XRD, SEM and EDX methods. The photocatalytic activity of the synthesized materials were investigated by the decolorization of methylene blue dye as a model compound under UV or halogen light irradiation as followed by spectrophotometric monitoring at room temperature. The synthesized SnO2 nanoparticles show excellent photocatalytic activity under UV or visible light irradiation. The decolorization efficiency of MB dye solution after 20 min exposure time is 100% under UV light where efficiency of SnO2 is only 56% after 120 min under visible light irradiation. Photocatalyst load is a little amount of photocatalyst (0.6 g/L). In this working, also different photocatalyst loading amounts have been done. At the end, reusage tested 5 times and it shows that our photocatalyst is photostable.Article Citation - WoS: 38Citation - Scopus: 39A Novel Polyaniline/Nio Nanocomposite as a Uv and Visible-Light Photocatalyst for Complete Degradation of the Model Dyes and the Real Textile Wastewater(SPRINGER HEIDELBERG, 2020-10-02) Haspulat Taymaz, Bircan; Eskizeybek, Volkan; Kamış, Handan; Taymaz, Bircan HaspulatThe textile processing industry utilizes enormous amounts of water. After the dying process, the wastewater discharged to the environment contains carcinogens, non-biodegradable, toxic, and colored organic materials. This study aimed to develop a nanocomposite material with improved photocatalytic activity to degrade textile dyes and without a need for a post-separation process after the use. For this, nickel oxide nanoparticles (NiO NPs) were synthesized by a simple method in aqueous media. Then, NiO-doped polyaniline (PANI/NiO) with efficient absorption in the visible region (optical band gap of 2.08 eV) synthesized on a stainless steel substrate with electropolymerization of aniline in the aqueous media. The photocatalytic activity of PANI/NiO film was also investigated by the degradation of model dyes. Under UV and visible light irradiation, the PANI/NiO film degraded methylene blue and rhodamine B dyes entirely in 30 min. Moreover, the PANI/NiO film was also utilized to degrade real textile wastewater (RTW) without applying any pre-process; it was entirely decomposed by the nanocomposite film in only 45 min under UV light irradiation. The photocatalytic reaction rate of the pure PANI film is increased as 2.5 and 1.5 times with the addition of NiO NPs under UV and visible light irradiations for degradation RTW, respectively. The photocatalytic efficiency was attributed to reduced electron-hole pair recombination on the photocatalyst surface. Furthermore, the photocatalytic stability is discussed based on re-use experiments. The photocatalytic performance remains nearly unchanged, and the degradation of dyes is kept 94% after five cycles.Article Citation - WoS: 17Citation - Scopus: 24Photocatalytic Degradation of Organic Dyes With Magnetically Separable Pani/Fe3o4 Composite Under Both Uv and Visible-Light Irradiation(John Wiley and Sons Inc, 2022-02-08) Demir, M.; Haspulat Taymaz, Bircan; Sarıbel, M.; Kamış, Handan; Taymaz, Bircan HaspulatThe creation of a novel composite photocatalyst has gained great attention in the field of organic dye remediation. Herein, the PANI/Fe3O4 photocatalyst has been prepared using the chemical oxidative polymerization of aniline. The as-prepared photocatalyst represents a denser and uniform morphology along with strong magnetic properties. The photocatalytic activity of the PANI/Fe3O4 was investigated for the degradation of Malachite Green (MG), Jakazol Kala (JK) and Levafix Red (LR). In the presence of PANI/Fe3O4 composite, the reaction rate constants were found to be 0.1997, 0.0521, and 0.1993 min?1 for MG, JK and LR, under UV-light irradiation and 0.0522, 0.0491, 0.0544 min?1 under visible light irradiation, respectively. The nanocomposite can be easily separated from the treated water and reused several times. The suppression of electron recombination, the reduced bandgap and the broad light-harvesting in both UV and visible-light regions contribute to the advanced photocatalytic performance of the PANI/Fe3O4. © 2022 Wiley-VCH GmbHArticle Electrochemical Production of Zno and Zno@ag Core-Shell Nanorods on Ito Substrate and Their Photocatalytic and Photoelectrochemical Performance(2019-09-30) Kamış, Handan; Karakuş Duyar, Nadiye; Haspulat Taymaz, BircanZinc oxide (ZnO) and Ag deposited ZnO (ZnO@Ag) core-shell nanorods produced electrochemically on indium tin oxide coated glass (ITO) substrate for the first time without any organic surfactants or high annealing temperature. Nanorod films were synthesized two-step synthesis procedure. Firstly, ZnO nanorods electrodeposited at low temperature, in second step, in situ electrochemically etching of deposited ZnO nanorod was carried out. Characterizations of electrochemically produced films have been carried by using morphologic, spectroscopic and structural analysis methods by using X-ray diffraction (XRD), scanning electron microscope (SEM), atomic force microscope (AFM), fourier transform infrared spectroscopy (FTIR), Elemental mapping, UV-visible diffuse absorption spectra and photoluminesance spectroscopy (PL). The photocatalytic performance of the obtained films was determined by degradation of methylene blue and malachite green dyes under UV light illumination. Methylene blue and malachite green dyes completely degraded under UV light irradiation after 150 and 180 min, respectively. Also, photoelectrochemical (PEC; water splitting) performances of the produced films were investigated under dark conditions and UV light irradiation. The ZnO@Ag core-shell nanorods exhibited higher photocatalytic and photoelectrochemical performance in comparison with unmodified ZnO nanorods film. The nanorods grown on the ITO substrates showed very good photocatalytic activity and became reusable without significant loss of activity.Article Citation - WoS: 4Citation - Scopus: 4Synthesis of New Azobenzo[c]cinnolines and Investigation of Electronic Spectra and Spectroelectrochemical Behaviours(PERGAMON-ELSEVIER SCIENCE LTD, 2021-12-01) Nalcıoğlu, Öznur Ölmez; Kılıç, Emine; Haspulat Taymaz, Bircan; Kamış, Handan; Taymaz, Bircan HaspulatA series of disazobenzo[c]cinnoline dyes was prepared by coupling reaction of 3,8-dihydroxybenzo[c]cinnoline with diazotised aromatic amines. The structures of these dyes were confirmed using UV-Vis, FTIR, H-1 NMR, LC-MS/MS and LC-MS/TOF spectroscopic techniques. C-13 NMR, C-13-DEPT, H-1-H-1 COSY, H-1-C-13 HMQC and H-1-C-1(3) HMBC spectra of dye 12 were demonstrated in this study. In addition, the effects of the substituent attached to the phenyl ring, solvent and acid-base on the UV-Vis spectra of the dyes were investigated. Besides, voltammetric and spectroelectrochemical behaviours of four disazobenzo[c]cinnolines (2, 8, 11 and 13) in acetonitrile (ACN) solution were also evaluated. It was observed that the disazobenzo[c]cinnoline derivatives indicated reversible voltammetric behaviour in acetonitrile-tetrabutylammonium perchlorate (ACN-TBAP) solution. A square-wave potential step method coupled with optical spectroscopy was used to probe switching times and optic contrast of the dyes. (C) 2021 Elsevier B.V.

Also, the photocatalytic performance of m-Co3O4 NPs was evaluated in synthetic wastewater. The produced m-Co3O4 NPs were ferromagnetic with a saturation magnetization value of 4.3 emu g−1 and the degradation of cationic MB and anionic DY-50 dyes by 100% and 93% in 20 min and 35 min, respectively, by adsorption-assisted photocatalytic process under visible light was achieved. The reactions were found to be pseudo-second-order equation for the adsorption-assisted photocatalytic process for both dyes. The photocatalytic activity of m-Co3O4 NPs decreased slightly even after five repeated cycles. These results show that the m-Co3O4 NPs can be used successfully in dye treatment in wastewater with their adsorption-assisted photocatalytic properties, activation by visible light, magnetic separability, and low-cost production. © 2024 Taylor & Francis Group, LLC.Article Citation - WoS: 3Citation - Scopus: 3Enhancing Structural Health Monitoring of Fiber-Reinforced Polymer Composites Using Piezoresistive Ti3c2tx Mxene Fibers(Nature Research, 2025-01-19) Taymaz, B.H.; Kamış, H.; Dziendzikowski, M.; Kowalczyk, K.; Dragan, K.; Eskizeybek, V.The anisotropic behavior of fiber-reinforced polymer composites, coupled with their susceptibility to various failure modes, poses challenges for their structural health monitoring (SHM) during service life. To address this, non-destructive testing techniques have been employed, but they often suffer from drawbacks such as high costs and suboptimal resolutions. Moreover, routine inspections fail to disclose incidents or failures occurring between successive assessments. As a result, there is a growing emphasis on SHM methods that enable continuous monitoring without grounding the aircraft. Our research focuses on advancing aerospace SHM through the utilization of piezoresistive MXene fibers. MXene, characterized by its 2D nanofiber architecture and exceptional properties, offers unique advantages for strain sensing applications. We successfully fabricate piezoresistive MXene fibers using wet spinning and integrate them into carbon fiber-reinforced epoxy laminates for in-situ strain sensing. Unlike previous studies focused on high strain levels, we adjust the strain levels to be comparable to those encountered in practical aerospace applications. Our results demonstrate remarkable sensitivity of MXene fibers within low strain ranges, with a maximum sensitivity of 0.9 at 0.13% strain. Additionally, MXene fibers exhibited high reliability for repetitive tensile deformations and low-velocity impact loading scenarios. This research contributes to the development of self-sensing composites, offering enhanced capabilities for early detection of damage and defects in aerospace structures, thereby improving safety and reducing maintenance expenses. © The Author(s) 2025.Article Citation - WoS: 9Citation - Scopus: 9Electrochemical Preparation of Donor-Acceptor Type Conjugated Polymer Films: Effect of Substitute Units on Electrochromic Performance(ELSEVIER, 2021-01-01) Akgül, Eda Tağa; Üzdürmez, Ahmet Ferat; Kamış, Handan; Kılıç, Emine; Demir, MüslümConjugated polymers exhibiting adjustable color changes under an electric field have been receiving great research interest due to their potential use in electrochromic applications. High-performance electrochromic materials are required to have well-defined donor-acceptor (D-A) units, a low optical bandgap, and fast response time. To fulfill these demands, herein, for the first time, two conducting macromolecules poly-3,8-diaminobenzo [c]cinnoline (P1) and poly-4,7-bis(phenyldiazenyl)benzo[c]cinnoline-3,8-diamine (P2) were successfully fabricated on the ITO substrate via electrochemical polymerization from their corresponding monomers in 0.1 M TBAP/acetonitrile solution. Consequently, two conjugated polymeric films show well-defined azo and amine functional groups, which are responsible for electron-withdrawing and electron-donating, respectively. The optical bandgaps (E-g) of P1 and P2 films were found 1.87 eV and 1.81 eV, respectively. The P1 exhibited a yellowish-brown color in neutral states and reduced states and a dark brown color in oxidized states while the P2 showed an orange color in neutral states, brownish orange color in oxidized states and a dark brown color in reduced states. It has been found that the P1 shows a higher conductivity, shorter switching time and better stability while P2 exhibits advanced the chromic and electron-withdrawing characteristics, which were attributed to the substituted phenyldiazenyl units contacted to the benzo[c]cinnoline (BCC) and lower oxidation potential of P2. This study opens a new avenue into the electrochromic application via the effective electropolymerization of corresponding monomers.Article Citation - WoS: 13Citation - Scopus: 15Electrochemical Immunosensor for Individual and Simultaneous Determination of Cytokeratin Fragment Antigen 21-1 and Neuron-Specific Enolase Using Carbon Dots-Decorated Multiwalled Carbon Nanotube Electrode(Elsevier, 2022-12-01) Filik, Hayati; Avan, Asiye Aslihan; Puntar, Nilay Altas; Özyürek, Mustafa; Çakıcı, Maside; Guengor, Zeynep Banu; Kamış, Handan; Altaş Puntar, Nilay; Güngör, Zeynep BanuIn this approach, we fabricated a sandwich-type electrochemical immunosensor for individual and simultaneous sensing of cytokeratin fragment antigen 21-1 (CYFRA 21-1) and neuron-specific enolase (NSE) using the multiple-label concept. In this report, carbon dots (CDs) were prepared from citric acid and ethylenediamine (EDA). A hybrid EDA-CDs-MWCNTs composites were prepared and then decorated with gold nanoparticles (AuNPs). The obtained hybrid composites were used as an immunosensing platform. Furthermore, AuNPs decorated EDA-CDs-MWCNTs was carefully loaded with reactive dye (orange G and carminic acid) and utilized as signal labels. The surface morphology and the electrochemical properties of the modified SPCE were studied carefully. The linear range for the individual and simultaneous detection was 0.002-10 ng mL-1 for the CYFRA 21-1 and NSE and the detection limits (LODs) were 0.22 pg mL-1 and 0.15 pg mL-1 for the individual detection while 0.25 pg mL-1 and 0.20 pg mL-1 for simultaneous detection, respectively. This developed immunoassay was utilized for the assessment of two markers in the serum sample with reasonable consequences.
