A relationship between the tensile yield stress and grain size i.e., Hall-Petch (H–P) law, for an ultrafine-grained (UFG) Zn was experimentally evaluated for the first time. In reality, it is problematic to assess this prediction using experimental

Abstract Alcobiosis, the symbiosis of algae and corticioid fungi, frequently occurs on bark and wood. Algae form a layer in or below fungal basidiomata reminiscent of the photobiont layer in lichens. Identities of algal and fungal partners were confi
