Effect of vanadium replacement by zirconium on the electrochemical behavior of Ti6Al4V alloy in Ringer´s solution
Environmental Engineering and Management Journal › Vol. 7 › Nr. 6 AbstractThe electrochemical behaviour of Ti6Al4V and Ti6Al4Zr alloys has been evaluated in Ringer's solution at 250C. The effect of the substitution of vanadium in Ti6Al4V alloy has been specifically addressed. The evaluation of the corrosion resistance was carried out through the analysis of the open circuit potential variation with time, potentiodynamic polarization curves, and electrochemical impedance spectroscopy (EIS) tests. Very low current densities were obtained (order of nA/cm2) from t... Autori: Adrian Cailean, Daniel Mareci, Daniel Sutiman, Igor Creţescu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=25334

Glucose oxidase - vanadium substituted anionic clay as bionanocomposite formulations for biosensors applications
Environmental Engineering and Management Journal › Vol. 8 › Nr. 1 AbstractChemical sensors utilizing immobilized enzymes and proteins are important for monitoring chemical processes and biological systems. Glucose oxidase (GOx) from Aspergillum Niger is a flavoenzyme that has been used to determine glucose. Among the conventional methods of enzyme deposition the main strategy consists in its entrapment in an inert matrix adsorbed on the electrode surface. We report here the synthesis and physical – chemical characterization of a new bionanocomposites obtaine...

IN SITU STUDY OF THE ELECTRICAL/DIELECTRIC PROPERTIES OF ALUMINA SUPPORTED VANADIA USED AS COMBUSTION CATALYSTS
Environmental Engineering and Management Journal › Vol. 11 › Nr. 1 The synthesis of vanadium oxide systems (with 5 and 20 wt% V2O5 loadings) supported on commercial γ-alumina was carried out by a wet impregnation method. The samples were characterized by low-temperature nitrogen adsorption (BET), inductively coupled plasma (ICP) method and by in situ electrical conductance/capacitance measurements. The adsorption of CO was used to investigate the acidic properties of alumina support and V2O5/-Al2O3 catalysts by FTIR spectroscopy. The catalytic acti...

APPLICATION OF BASIC OXYGEN FURNACE (BOFS) IN AGRICULTURE: A STUDY ON THE ECONOMIC VIABILITY AND EFFECTS ON THE SOIL
Environmental Engineering and Management Journal › Vol. 18 › Nr. 6 Slags are the main by-products from steelmaking cycle, which are currently recycled inside the steel industry as well as in other
sectors with significant environmental and economic benefits. As in Italy slags application is not yet allowed in agriculture, the
paper aims at evaluating the technical and economic feasibility of a slag treatment plant, to obtain a product to be sold in the fertilizer
market as soil amendment. A preliminary assessment of the fate of some trace metals (Cr, V, Sb a... Autori: Teresa Annunziata Branca ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28012
