The results of some recent theoretical and experimental investigations
on the physics of superheated emulsions are presented. Computational
fluid thermodynamics allowed for a detailed description of the tempora
l and spatial history of the energy deposition process by a charged pa
rticle in a superheated liquid. Despite the assumptions it is based up
on, this model gives information in agreement with experimental data o
n bubble nucleation. The experimental findings concern the role of int
erfacial reactions between drops and emulsifer, the existence of inhib
ition temperatures for the detector's response, and the progressive se
nsitisation to protons.
