Аннотация:
We summarize the results of a recent positron annihilation study of the phase behaviour of confined in Vycor glass. Particular emphasis is placed on the phase diagram of the confined fluid and on the usefulness of the positron annihilation technique in determining the mechanisms underlying phase transitions of fluids in porous solids.
