Shock formation in the collapse of a vapor nano-bubble [PDF]
, 2014 In this paper a diffuse-interface model featuring phase change, transition to supercritical conditions, thermal conduction, compressibility effects and shock wave propagation is exploited to deal with the dynamics of a cavitation bubble. At variance with

Supercritical Fluid Extraction [PDF]
, 2014 Supercritical fluid extraction (SFE) has become one of the most popular green extraction techniques nowadays since it has demonstrated many advantages compared with traditional or classical extraction processes. Aspects such as improved selectivity, higher extraction yields, better fractionation capabilities, and lower environmental impacts have been ...
