Vibration-induced dynamical weakening of pyroclastic flows: Insights from rotating drum experiments
(Wiley-Blackwell, 2015)
Pyroclastic flows are characterized by their high mobility, which is often attributed to gas fluidization of the usually fine and/or low-density particles. However, the physical mechanism that might drive sustained ...

Role of looping-calcination conditions on self-reactivation of thermally pretreated CO2 sorbents based on CaO
(American Chemical Society, 2013)
The conversion of thermally pretreated CaO along successive carbonation/calcination cycles has been investigated, as affected by looping-calcination conditions, by means of Thermogravimetric Analysis (TGA). Sorbent samples ...
