The recycling of spent automotive batteries is essential for minimizing their environmental impact. This requires eco-innovative methods with low cost and energy use. present study explores the battery electrodes through melt quenching method, a process that incorporates anode cathode plates into vitreous host matrix. Samples xCuO·10Sb2O3·(90 − x)[4PbO2·Pb] composition, where x = 0 to 30 mol% CuO, were prepared by method. XRD analysis indicates vitroceramic structures obtained samples. Thus,...
Abstract The potential of excitation - emission matrices (EEM) measurements using classical right angle technique, in conjunction with chemometrics, was prospected for white wine classification respect to their cultivar and geographical origin. For this purpose, wines belonging four cultivars (Chardonnay, Pinot Gris, Riesling Sauvignon) from two different countries (Romania France) were investigated. – statistically processed parallel factor analysis (PARAFAC). According Soft Independent...
This study explores the physical, radiation shielding, optical, and photoluminescent properties of PbO2-SiO2-based glass systems. Traditional shielding materials, like lead concrete, face challenges due to toxicity weight. Glass materials provide an alternative, offering transparency efficiency. Four systems were analyzed: PbO2-SiO2 (PS), PbO2-SiO2-CeO2 (PSC), PbO2-SiO2-Eu2O3 (PSE), PbO2-SiO2-Yb2O3 (PSY). The results show that rare earth elements densify network, thereby enhancing...
There is a growing awareness that titania (TiO2) and TiO2-based oxide systems are the most promising candidates for development of photoelectrodes photoelectrochemical cell (PEC) solar-hydrogen production [1]. The PEC equipped with single photoelectrode (photoanode) cathode, both which immersed in an aqueous electrolyte. In this work we present sol-gel method to prepare TiO2 thin films on ITO using tetraisopropoxides titanium, acetylacetone, 1-butanol Tween 80 as surfactant. were deposited...
Glass ceramics in the xMnO2·(100-x)[4PbO2·Pb] system where x = 0-20% MnO2 were prepared and investigated by XRD, SEM, FTIR, UV-Vis, PL, EPR, Raman XAFS spectroscopies cyclic voltammetry measurements. The FTIR data indicate that accommodation of structure with increasing manganese content can be realized intercalation [MnOn] [PbOn] structural units formation Mn-O-Mn linkages. XANES EXAFS show for lower dopant contents ions adopt octahedron configurations distorted oxygen while at higher...
