Inferring the effects of compositional boundary layers on crystal nucleation, growth textures, and mineral chemistry in natural volcanic tephras through submicron-resolution imaging

Crystal nucleation and growth are first order processes captured in volcanic rocks and record important information about the rates of magmatic processes and chemical evolution of magmas during their ascent and eruption.We have studied glass-rich andesitic tephras from the Central Plateau of the Southern Taupo Volcanic Zone by electron- and ion-mic

Differences in the biochemical content and radical scavenging activity of propolis from different parts of a Meliponula ferruginea hive

Research on stingless bee products has increased in recent years, and of particular interest is propolis because of its biological activities such as antioxidant and antimicrobial.However, there is paucity of information regarding intra-hive variations in the biochemical composition and biofunctional properties of this propolis.In this study, we in
