Evaluation Of Antioxidant Activity Of Crataegus Species Collected From Different Regions Of Turkey
(Acg Publications, 2012)
Crataegus species (Rosaceae), known as "Howthorn" have found special medicinal use for the treatment of mild heart diseases. This work aims to measure the antioxidant capacities of various Crataegus species growing in ...
Chemical Characterization Of 64 Propolis Samples From Hakkari, Turkey
(Acg Publications, 2018)
Propolis is a resinous substance produced by honey bees from various plants they visit. Sixty-four propolis samples were collected from different localities of four districts (Merkez, Yiiksekova, Semdinli, and Qukurca) in ...
Electron Spray Ionization Mass Spectrometry And 2D P-31 Nmr For Monitoring O-18/O-16 Isotope Exchange And Turnover Rates Of Metabolic Oligophosphates
(Springer Heidelberg, 2012)
A new method was here developed for the determination of O-18-labeling ratios in metabolic oligophosphates, such as ATP, at different phosphoryl moieties (alpha-, beta-, and gamma-ATP) using sensitive and rapid electrospray ...
A Combined First Principles TDDFT and Experimental Study on the Uv-Vis Spectra Properties of M(P-Nitrophenyl Azo Resorcinol)(3) Complexes (M: Fe, Cr)
(Scientific Technical Research Council Turkey-Tubitak, 2014)
UV-Vis absorption data of p-nitrophenyl azo resorcinol (Magneson I) and its 2 Fe(III) and Cr(III) complexes were investigated both experimentally and theoretically. The geometries were optimized at BP86/TZVP level. The ...
Electroanalysis And Electrocatalysis Using Poly(Vinylferrocenium) Perchlorate Coated Electrodes
(Blackwell Science Ltd, 1997)
Electroanalytical applications based on the electrochemical behavior of the redox polymer, poly(vinylferrocenium) perchlorate (PVF+ClO4-) coated as a film on Pt surfaces, are described. This chemically modified surface is ...
Electrochemically Generated Catalyst System With Increased Specificity And Efficiency For Olefin Metathesis
(Elsevier Science Sa, 2003)
A facile route for the electrochemical generation of an olefin metathesis catalyst from methylene chloride solution Of WCl6 was described. It was found that reductive, oxidative and pulse electrolysis produced the same ...
Preconcentration and Determination of Lead, Cadmium and Nickel From Water Samples Using a Polyethylene Glycol Dye Immobilized on Poly(Hydroxyethylmethacrylate) Microspheres
(Japan Soc Analytical Chemistry, 2006)
A simple and sensitive preconcentration analysis-atomic absorption spectrometric procedure is described for the determination of lead, cadmium and nickel. The method is based upon on-line preconcentration of metal ions on ...
A Novel Two-Enzyme Amperometric Electrode For Lactose Determination
(Japan Soc Analytical Chemistry, 2002)
Coimmobilization of beta-galactosidase and glucose oxidase in a redox polymer, polyvinylferrocenium perchlorate (PVF+ClO4-), led to the development of an enzyme electrode for the determination of lactose. The amperometric ...
Boric Acid: A Simple Molecule of Physiologic, Therapeutic and Prebiotic Significance
(Walter De Gruyter Gmbh, 2015)
Boric acid, H3BO3, is a weak acid and at physiological pH is in the form of an uncharged small molecule. Behaving as a Lewis acid, it forms complexes with amino-and hydroxy acids, carbohydrates, nucleotides and vitamins ...
Caffeine Degradation in Water by Gamma Irradiation, Zonation and Zonation/Gamma Irradiation
(Inst Nuclear Chemistry Technology, 2014)
Aqueous solutions of caffeine were treated with ozone and gamma irradiation. The amounts of remaining caffeine were determined after solid phase extraction as a function of absorbed dose and ozonation time. In addition to ...
