FeS₂/ZnO core/shell nanowires: structural, optical and electrochemical properties. by Retana Betancourt, María Fernanda

“…Altough, many efforts have been done in order to find the characteristics and properties that allow the subsequent production and commercialization, hybrid solar cells represent an interesting option for this purpose. The composition in the photoactive layer is key in order to obtain high values of efficiencies and where the use of nanosized materials with one-dimensional morphology embedded into polymeric matrix allows the improvement of their optoelectronic properties. …”

Effects of the fe/Mn Weight ratio and cooling rate on the area fractions of α-AlFeSi AND β-AlFeSi Phases in Al-7.5Si-3.75Cu-0.5Mg-0.55Fe-xMn Aluminum alloy by Hernández Rodríguez, Alejandra Nohemí, Castro Román, M. de J., Herrera Trejo, M., Belmares Perales, S., Orozco González, Pilar

“…The amount, size and shape of these iron compounds depend largely on the cooling conditions and on the chemical composition, especially the level of iron in the melt [5]. β-Al5FeSi-needles iron compounds have usually been considered most detrimental to the mechanical properties of Al-Si alloys because of the brittle features and stress concentration caused by the needle-like morphology. …”
