Abstract

An overview of experimental work recently performed in the Lisbon laboratories is provided. Several physical properties of liquids as well as those of the coexistence between two liquid phases and between liquid and solid have been determined at absolute negative pressures. Examples for this include thermal pressure coefficients, loci of temperature of maximum density, negatively sloped melting lines, speed of propagation of low-intensity ultrasound waves, and (p, T, x) conditions of occurrence of liquid-liquid phase separation. The major achievements that emerged within the scope of this research program were: (i) the first experimental evidence for the existence of a TMD in supercooled and stretched gallium, and (ii) the first experimental detection of phase separation phenomena in molecular liquid mixtures under tension.
