Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

When considering the rheology of a suspension the fundamental physical aspect to be
quantified is the redistribution of strain between the deformable matrix fraction of the …

In June 2011, an eruption of rhyolite magma began at the Puyehue–Cordón Caulle volcanic
complex, southern Chile. By January 2012, explosive activity had declined from sustained …

Abstract The 2021 Tajogaite eruption of Cumbre Vieja (La Palma, Spain) was typified by the
emission of low viscosity lavas that flowed at high velocities and inundated a large area. We …

Magma ascending through Earth's crust undergoes complex chemical and physical changes
that may induce crystallization, a process that contributes to lead the magmatic system …

Storage and transport of silicate melts in the Earth's crust and their emplacement on the
planet's surface occur almost exclusively at sub-liquidus temperatures. At these conditions …

Glasses with different Bi 2 O 3 contents (37–42 mol%) have been prepared by conventional
melt quench technique. The IR and Raman studies indicate that these glasses are made up …

Quench fragmentation is a non-explosive process that occurs when molten magma is super-
cooled to glass upon contact with ambient water. This occurs when coherent lavas are …

We have investigated the effect of undercooling and deformation on the evolution of the
texture and the crystallization kinetics of remelted basaltic material from Stromboli (pumice …

Experiments were conducted to determine the water solubility of alkali basalts from Etna,
Stromboli and Vesuvius volcanoes, Italy. The basaltic melts were equilibrated at 1,200° C …
