Article Citation - WoS: 7Citation - Scopus: 9Evaluation of Extra Virgin Olive Oil Compounds Using Computational Methods: in Vitro, Admet, Dft, Molecular Docking and Human Gene Network Analysis Study(Bmc, 2025) Unsal, Velid; Yildiz, Resit; Korkmaz, Aziz; Mert, Basak Dogru; Caliskan, Cemile Gunbegi; Oner, ErkanThis study investigates the phenolic compounds (PC), volatile compounds (VC), and fatty acids (FA) of extra virgin olive oil (EVOO) derived from the Turkish olive variety "Sar & imath; Ulak", along with ADMET, DFT, molecular docking, and gene network analyses of significant molecules identified within the EVOO. Chromatographic methods (GC-FID, HPLC) were employed to characterize FA, PC, and VC profiles, while quality parameters, antioxidant activities (TAC, ABTS, DPPH) were assessed via spectrophotometry. The analysis revealed a complex composition of 40 volatile compounds, with estragole, 7-hydroxyheptene-1, and 3-methoxycinnamaldehyde as the primary components. Hydroxytyrosol, tyrosol, oleuropein, apigenin, ferulic acid, and vanillic acid emerged as main phenolic constituents, with hydroxytyrosol and apigenin exhibiting high bioavailability. Molecular docking highlighted oleuropein and pinoresinol as compounds with strong binding affinities, though only hydroxytyrosol, apigenin, and pinoresinol fully met Lipinski and other drug-likeness criteria. DFT analysis showed that oleuropein and pinoresinol have notable dipole moments, reflecting polar and asymmetrical structures. KEGG enrichment analysis further linked key molecules like oleuropein and apigenin with pathways related to lipid metabolism and atherosclerosis, underscoring their potential bioactivity and relevance in health-related applications.Article Citation - WoS: 26Citation - Scopus: 30Protection of Mild Steel From Corrosion in Hcl Solution Via Green Rumex Acetosella Extract: Experimental and Theoretical Studies(Elsevier, 2024) Arslanhan, Selim; Sigircik, Gokmen; Yildiz, Resit; Baran, Mehmet FiratThe efficiency and potential of green Rumex acetosella extract (RAE) RAE ) on the inhibition of the mild steel (MS) corrosion were investigated in the acidic environment. The high inhibitive capability of RAE on the mild steel was studied by electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) techniques. In addition, potentiodynamic (PD) polarization measurements were carried out to examine corrosion mechanism. The achieved electrochemical tests showed that RAE has a significant inhibition effect on mild steel corrosion. The results of surface analysis recorded by scanning electron microscopy (SEM), and atomic force microscopy (AFM) depicted that RAE provide strong protective layer on the steel surface via adsorptive groups. The inhibition efficiency was calculated as 99.7 %, and 99.6 % from LPR and EIS after 120 h exposure time. Adsorption free energy ( Delta G oads ) value is found as-29.79 kJ mol-1,- 1 , indicating that both physical and chemical adsorptions occur. Furthermore, the obtained experimental findings were supported with quantum chemical calculation results.Article Adsorption and inhibition effect of 2,4-diamino-6-hydroxypyrimidine for mild steel corrosion in HCl medium: experimental and theoretical investigation, Ionics(Ionics, 2019) Yıldız, Reşit2,4-Diamino-6-hydroxypyrimidine (2D6H) was examined as corrosion inhibitor of mild steel (MS) in 0.1 M HCl using potentiodynamic measurements, linear polarization resistance (LPR), scanning electron microscopy, electrochemical experiments, and quantum chemical calculations. All measurements show that the corrosion inhibition effectiveness is forthright compared to the concentration of 2D6H ranging from 0.5 to 10.0 mM. Adsorption of 2D6H on the MS surface in the presence of HCl is determined to obey Langmuir adsorption isotherm. The electronic features elucidated by quantum chemical calculations were associated with the experimental inhibition productivities. The mechanism of inhibition was revealed by Epzc measurements.Presentation Sodyum Dietil Ditikarbamat Trihidrat (SDTT)’ın İnhibitör Olarak Asidik Ortamda Yumuşak Çelik Korozyonuna Elektrokimyasal Davranışının İncelenmesi(14th International Corrosion Symposium, 2016) Sarı, Ayşen; Yıldız, Reşit; Dehri, İlyas…Article The Study of 2, 4-Diamino-6-methly-1, 3, 5-triazine on the Corrosion Inhibition of Mild Steel in The Hydrochloric Acid Medium: Integrated Theoretical and Experimental Investigations(Bingol University, 2023) Yıldız, ReşitThe aim of this study is the investigation of adsorption and corrosion behaviors of 2,4-Diamino-6-methly-1,3,5-triazine (2-DMT) on mild steel (MS) in 0.5 M HCI solution using many experimental and theoretical studies such as potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR), adsorption isotherm, potential of zero charge (PZC), scanning electron (SEM), atomic force microscopies (AFM) and quantum chemical calculations. The results showed that 2-DMT has an outstanding anti-corrosion performance of 94.6% at an optimum concentration of 10 mM and the MS surface, which was exposed to the inhibited solution at 298 K, does not contain pits, cracks or deformations. Values of icorr are found to be 0.51, 0.22, 0.098, 0.072 and 0.039 mA cm-2 for blank solution and each concentration of 2-DMT. Hydrogen volumes are 90 and 4.6 mL cm-2 for blank solution and the existence of 10.0 mM 2-DMT, respectively. The observed adsorption is much more consistent with Langmuir. The high performance is explained by the effective adsorbing of organic matter to the MS surface. HOMO, LUMO energies and the energy gap (∆E) are -7.1980, -1.9959 and 5.2021 eV, respectively. Accordingly, it is suggested that this organic compound can be used in the industrial acid cleaning procedure.Article Citation - WoS: 9Citation - Scopus: 10Green Synthesis of Silver Nanoparticles Derived from Papaver rhoeas L.

In this article, the spectroscopic (ultraviolet-visible (UV-vis), electron-dispersing X-ray (EDX), and Fourier transform infrared (FT-IR)), microscopic (field emission scanning electron microscope (FE-SEM), transmission electron microscope (TEM), and atomic force microscope (AFM)), structural (X-ray diffractometer (XRD) and zetasizer), and analytic (thermogravimetric/differential thermal analyzer (TGA-DTA)) characterization of the silver nanoparticles (AgNPs) produced from Papaver rhoeas (PR) L. leaf extract are presented. PR-AgNPs are generally spherical and have a maximum surface plasmon resonance of 464.03 nm. The dimensions of the manufactured nanomaterial are in the range of 1.47-7.31 nm. PR-AgNPs have high thermal stability and a zeta potential of 36.1 mV. The minimum inhibitory concentration (MIC) values (mg L-1) of PR-AgNPs on Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, and Candida albicans are 1.50, 0.75, 3.00, 6.00, and 0.37, respectively. In the study, the cytotoxic and proliferative effects of PR-AgNPs using the MTT (3-(4,5-dimethylthiazol-2-yl)-diphenyltetrazolium bromide) method on various cancer cell lines (CACO-2 (human colon adenocarcinoma cell), MCF-7 (human breast cancer cell), T98-G (glioblastoma multiforme cell), and healthy HUVEC (human umbilical vein endothelial cell)) cell lines are presented. After 24 and 48 h of the application, the half-maximum inhibitory concentration (IC50) values (mu g mL(-1)) of PR-AgNPs on HUVEC, CACO-2, MCF-7, and T98-G lines are 2.365 and 2.380; 2.526 and 2.521; 3.274 and 3.318; 3.472 and 3.526, respectively. Comprehensive in vivo research of PR-AgNPs is proposed to reveal their potential for usage in sectors such as nanomedicine and nanochemistry.Article Citation - WoS: 7Citation - Scopus: 8Trans-Chalcone Attenuate Arsenic-Induced Toxicity in 3t3 Embryonic Fibroblast Cells; An In Vitro And In Silico Study(Elsevier, 2024) Unsal, Velid; Yildiz, Resit; Cicek, Mustafa; Gungor, Meltem; Kurutas, Ergul BelgeThis study investigated the curative role of trans-chalcone, a flanovide, against arsenic toxicity using in vitro and computer-based analyses.

Protection of metals with corrosion inhibitor is a popular topic. Considering environmental concerns and human health, it is more favorable to use green corrosion inhibitors than traditional corrosion inhibitors. Methanol extract of Arum dioscoridis (AD) becomes a potential green corrosion inhibitor and it can be used in industrial areas. Methods: Corrosion efficiency, corrosion behavior and corrosion mechanism of Arum dioscoridis leaf extract on mild steel (MS) are illuminated in 1 M HCl by Tafel curves, electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR), zero charge potential, structural and surface morphological analysis and density functional theory (DFT). Significant findings: The extract function as mixed-type corrosion inhibitor with predominantly cathodic action. Inhibition efficiency was reached the value of 97 %. Polarization resistance is measured as 761 Omega cm2 at 1000 ppm of AD. The high inhibition efficiency was attributed to phytochemicals in the AD extract. A high activation energy (70.34 kJ/mol) for inhibited solution than that of in blank solution (49.66 kJ/mol). Both physisorption and chemisorption are responsible for formation of a protective layer on MS surface to inhibit the electrochemical reactions. Optimized molecular structures in phytochemicals confirmed the inhibitive properties via DFT.Master Thesis Yumuşak Çeliğin HCL Asit Ortamından Koruması için Yeşil Korozyon İnhibitörü Olarak İğnelik Otu (Erodium Cicutarium) Ekstraktının Araştırılması(2025) Ergel, Buşra; Yıldız, ReşitBu çalışmada, iğnelik otu özütünün (Erodium cicutarium) 1 M HCl çözeltisi içindeki yumuşak çeliğin korozyonuna karşı inhibitör etkisi araştırılmıştır. Farklı sıcaklıklar ve derişimlerde yapılan deneylerde, inhibitör etkinliği elektrokimyasal yöntemlerle (PDP, EIS, LPR) değerlendirilmiştir. Sonuçlar, inhibitör derişimi arttıkça korozyonun azaldığını; sıcaklık yükseldikçe etkinliğin düştüğünü göstermiştir. İnhibitörlü ve inhibitörsüz ortamlarda 120 saat bekletilen çelik yüzeylerinin morfolojisi SEM, AFM, EDX ve XPS analizleriyle incelenmiştir. Elde edilen bulgular, EC özütünün yüzeye adsorplanarak koruyucu bir tabaka oluşturduğunu ortaya koymuştur. Hem anodik hem katodik tepkimeleri baskılayan bu özütün, karma tip inhibitör olarak davrandığı belirlenmiştir. Adsorpsiyonun Langmuir izotermine uyduğu görülmüş; ayrıca Arrhenius denklemi kullanılarak aktivasyon enerjileri hesaplanmıştır. ∆G° ads gibi termodinamik verilerle birlikte inhibitörün yüzey üzerindeki etkisi detaylandırılmıştır.Conference Object Electrochemical Hydrogen Production by Using G/Ni/Ag CathodeYıldız, Reşit; Doğru, Mert, Başak; Toprak Döşlü, SerapIn this study graphite (G) electrode was coated with nickel and decorated with silver (G/Ni/Ag) and we used this modified electrode as cathode in alkaline water electrolysis system.
