Carbon Nanotube Supported CdM(S, Se)/CdTe Anode Catalysts for Electrooxidation of Glucose in Alkaline Media

Hilal DEMİR KIVRAK | Nahit AKTAŞ

The sequential sodium borohydride (SBH, NaBH4) reduction method was utilized to prepare the 0.1 CdSe/CNT, 0.1 CdS/CNT, 0.1 (CdS-CNT)/CdTe, and 0.1 (CdSe-CNT)/CdTe catalysts. The XRD, SEM-EDS, TEM, and XPS analyses were used to characterize the catalysts. The electrochemical measurements were examined by cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) analyses for glucose electrooxidation. The characterization analyses revealed that the desired structure was formed on the support material. The electrochemical analysis results indicated that the ...Более

Fabrication of molecularly imprinted cotton fibers for quantification of streptomycin in honey samples

Nahit AKTAŞ

Streptomycin is a type of aminoglycoside used in treatment of several infections and with serious side effects in humans and animals, such as ototoxicity and nephrotoxicity. In the present study, we focused on the preparation of streptomycin-imprinted cotton fiber for rapid, sensitive and selective quantification of streptomycin in honey samples. The imprinted cotton fibers were characterized by attenuated total reflectance-Fourier transform spectroscopy, scanning electron microscopy, and x-ray photoelectron spectroscopy. In addition, the imprinted cotton fibers showed high adsorption capacity ...Более

p(thyme oil) and p(clove oil) organo-particles with biocompatible, anticancer, antioxidant, and antibacterial properties against Capan-1 and L-929 cells

Nahit AKTAŞ

The synthesis of p(ClO) and p(TO) organo-particles from clove oil and thyme oil is the first in the literature. The particles were tested against the L-929 cell line for cell viability/cytotoxicity. The anticancer activity was studied against the Capan-1 pancreatic cancer cell line. p(ClO) and p(TO) organo-particles were featured by thermogravimetry (TGA), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), particle size (DLS), and particle charge (zeta potential, Zeta) analyses. Antioxidant, biocompatible, antimicrobial, and in vitro cytotoxicity specialties w ...Более

Synthesis of poly(Oak bark) particles from oak bark extract and its utilization as a drug carrier material

Nahit AKTAŞ

As oak bark extract includes pharmaceutically meaningful precious biochemicals such as vanillic acid, quercetin, catechin, caffeic acid, gallic acid, ferulic acid, syringic acid, chlorogenic acid, q-coumaric and protocatechuic acid, the present study focuses on synthesizing polymeric particles from that extract while keeping their targeted natural bioactivity. In this study, due to the bioavailability of oak bark extracts, poly(Oak bark)water extract (p(OB)w), poly(Oak bark)ethanol extract (p(OB)e) and poly(Oak bark)water-ethanol extract (p(OB)we) particles were synthesized using redox polymer ...Более

Development of Nonenzymatic Benzoic Acid Detection on PdSn/GCE/Vulcan XC‐72R Prepared via Polyol Method

Nahit AKTAŞ

In this study a PdSn based sensor was developed for the determination of benzoic acid (BA) in foods. A carbon (Vulcan XC-72R) supported PdSn catalyst was prepared via polyol method and its surface electronic and chemical properties were investigated by advanced surface analytical techniques such as scanning electron microscopy (SEM), X-ray diffraction spectroscopy (XRD), X-ray Photoelectron Spectroscopy (XPS), temperature-programmed reduction with H-2 (TPR-H-2) and transmission electron microscopy (TEM). Electrochemical measurements were performed by employing cyclic voltammetry (CV) and diffe ...Более

The preparation, characterization, and electrooxidation of colloidal palladium modified poly(methacrylic acid) hydrogel as formic acid fuel cell anode catalyst

Nahit AKTAŞ

At present, poly(methacrylic acid) (MA), poly(MA) hydrogel, and Pd-doped poly(MA) hydrogel modified electrodes are constructed on graphite pencil (G). The Pd precursor is coated on the poly(MA)/G electrodes surface using the electrodeposition method. These electrodes are characterized by thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy, and scanning electron microscopy-energy dispersive X-ray. Poly(MA) hydrogel and Pd-doped poly(MA) hydrogel are successfully prepared by the polymerization and further electrodeposition. Formic acid electro-oxidation (FAEO) activities ar ...Более
