Oxygen reduction reaction on silver electrodes under strong alkaline conditions
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Oxygen reduction reaction (ORR) was studied on a silver polycrystalline electrode in different NaOH concentrations with a help of rotating disc and rotating ring disc electrodes. Soluble reaction intermediate was detected ...
Visible light-harvesting of TiO2 nanotubes array by pulsed laser deposited CdS
(Elsevier Science Bv, Amsterdam, 2014)
Titanium dioxide (TiO2) nanotubes arrays, obtained by anodization technique and annealing, were decorated with CdS using pulsed laser deposition method. Their structural, morphological and chemical characterization was ...
Immobilization of lipase on epoxy-activated Purolite((R)) A109 and its post-immobilization stabilization
(Elsevier Sci Ltd, Oxford, 2014)
In this study, Purolite (R) A109, polystyrenic macroporous resin, was used as immobilization support due to its good mechanical properties and high particle diameter (400 mu m), which enables efficient application in enzyme ...
Co(III) complex with (E)-2-(2-(pyridine-2-ylmethylene)hydrazinyl)-4-(4-tolyl)-1,3-thiazole: structure and activity against 2-D and 3-D cancer cell models
(Taylor & Francis Ltd, Abingdon, 2016)
Co(III) complex with a 2-hydrazonylthiazole ligand was synthesized and characterized by single-crystal X-ray diffraction. In the inner sphere of the complex, two monoionic ligands are coordinated tridentately forming ...
Corrosion of stainless steel 316Ti tank for the transport 12-15% of hypochlorite solution
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The corrosion of the transport tank materials made of stainless steel 316Ti is investigated in a solution containing 12-15% of the commercial sodium hypochlorite solution. Using the electrochemical techniques, weight loss ...
Voltammetric behavior of erythromycin ethylsuccinate at a renewable silver-amalgam film electrode and its determination in urine and in a pharmaceutical preparation
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Erythromycin, a macrolide antibiotic, has similar antimicrobial spectrum to penicillin and it is widely used, especially in the treatment of patients who are allergic to penicillin. In this work, the application of a ...
The influence of fly ash characteristics and reaction conditions on strength and structure of geopolymers
(Elsevier Sci Ltd, Oxford, 2015)
Reactivity of Class F fly ash (FA), development of strength, and structure of FA-based geopolymers, depending on the reaction conditions, were examined in this paper. The results of SEM/EDS and NMR analyses revealed that ...
Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, Amsterdam, 2015)
A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in ...
Interactions of Molecules with cis and trans Double Bonds: A Theoretical Study of cis- and trans-2-Butene
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
Noncovalent interactions of cis- and trans-2-butene, as the smallest model systems of molecules with cis and trans double bonds, were studied to find potential differences in interactions of these molecules. The study was ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, Ny physisorption, SEM, and ...
