Discovering fire events in the HAS1 settlement on the Dhofar coast (Oman) by a multi-methodological study of mollusk shells
Autor: Gaia Crippa, Silvia Lischi, Andrea Chiari, Monica Dapiaggi, Mauro Cremaschi
Mollusk shells from archeological deposits are often exposed to high temperatures through human-caused or natural heating events. While heat exposure affects reliability of mollusk shells for environmental reconstructions based on geochemistry, it ca

Evidence of manganese incorporation and distribution at the nanoscale in coccolithophore calcite
Autor: Cinzia Bottini, Monica Dapiaggi, Nicola Rotiroti, Gabriele Gambacorta, Chiara Bettoni, Remi Tucoulou
The coccolithophore algae (Calcihaptophycidae) produce an extracellular covering of calcium carbonate plates (coccoliths) and are responsible for up to 10% of global carbon fixation through photosynthesis and biomineralization. Therefore, any alterat

Structural Study of Nano-Sized Gahnite (ZnAl2O4): From the Average to the Local Scale
Autor: Giorgia Confalonieri, Nicola Rotiroti, Andrea Bernasconi, Monica Dapiaggi
Publikováno v: Nanomaterials, Vol 10, Iss 5, p 824 (2020)
Spinel gahnite (ZnAl2O4) has been obtained through a hydrothermal synthesis method with a grain size of about 2 nm. The sample was calcined for a few hours at two different temperatures (800 and 900 °C) in order to obtain larger grain sizes to be an

Publikováno v: Waste and Biomass Valorization. 12:6513-6521
Abstract The paper presents a quick method for the quantification of nickel species in spent FFC catalysts; the quantification of known quantities NiO and $$\hbox{NiAl}_2\hbox{O}_{4}$$ NiAl 2 O 4 is first done in a matrix of fresh zeolite Y, and then

At the microscale, C-S-H gels from alite, or neat Portland cements, has a Ca/Si ratio close to 1.80. At the nanoscale, C-S-H is described by a defective tobermorite structure which allows a maximum Ca/Si ratio close to 1.40. There is no agreement in

Coccolithophores are phytoplanktonic algae which produce an exoskeleton made of single platelets of calcite named coccoliths. They are widespread in all oceans and directly impact the short- and long-term C cycle. The study of coccolith size, morphol
