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 por 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. …”

Gold−Copper Nano-Alloy, “Tumbaga”, in the era of nano: phase diagram and segregation por Guisbiers, Grégory, Mejía Rosales, Sergio, Khanal, Subarna, Ruiz Zepeda, Francisco, Whetten, Robert L., Yacamán, Miguel José

“…One finds, for all the shapes investigated, that the congruent melting point of these nanoparticles is shifted with respect to both size and composition (copper enrichment). Segregation reveals a gold enrichment at the surface, leading to a kind of core–shell structure, reminiscent of the historical artifacts. …”

Uso de nanopartículas de carbono en la fabricación de corazones de arena para la fundición de aluminio por Aguirre Rojo, Ismael

“…En el Capítulo 3 se hace una profunda revisión bibliográfica acerca del uso de la nanotecnología como medio para obtener compósitos poliméricos con mejores propiedades térmicas y mecánicas que el polímero mismo, de donde se puede destacar que las nanopartículas de carbono tales como las nanoplacas de carbono (grafenos o GNP por sus siglas en ingles) y los nanotubos multipared son las más utilizadas para reforzar estas matrices poliméricas. …”

Assessing Conservation Values: Biodiversity and Endemicity in Tropical Land Use Systems por Moen, Jon, Waltert, Matthias, Bobo, Kadiri Serge, Kaupa, Stefanie, Montoya, Marcela Leija, Nsanyi, Moses Sainge, Fermon, Heleen

“…While many single-taxon studies have highlighted that species with narrow geographic ranges especially suffer from habitat modification, there is no multi-taxa study available which consistently focuses on geographic range composition of the studied indicator groups. We compiled geographic range data for 180 bird, 119 butterfly, 204 tree and 219 understorey plant species sampled along a gradient of habitat modification ranging from near-primary forest through young secondary forest and agroforestry systems to annual crops in the southwestern lowlands of Cameroon. …”
