Two-stage preheating is used in selective electron beam melting (SEBM) to prevent powder spreading during additive manufacturing (AM); however, its effects on part properties have not been widely investigated. Here, we employed three different prehea

Basaltic eruptions are the most common form of volcanism on Earth and planetary bodies. The low viscosity of basaltic magmas generally favours effusive and mildly explosive volcanic activity. Highly explosive basaltic eruptions occur less frequently

Basaltic eruptions are the most common form of volcanism on Earth and planetary bodies. The low viscosity of basaltic magmas inhibits fragmentation, which favours effusive and lava-fountaining activity, yet highly explosive, hazardous basaltic erupti

AMS radiocarbon dating of mortar: The case study of the medieval UNESCO site of Modena

Autor: Marta Caroselli, Fabio Marzaioli, Sara Nonni, Stefano Lugli, Lubritto Carmine, S. Marchetti Dori, Filippo Terrasi

The carbon dioxide contributing to binder formation during the set of a lime mortar reflects the atmospheric 14 C content at the time of construction of a building. For this reason, the 14 C dating of mortars is used with increasing frequencies in ar
