“…Similar depth profiles from different walls or fragments reveal clues to the social status of the builder and provide evidence if the walls have been prepared by the same workshop given the rooms have served similar functions [15]. On the other hand, depth profiles can reveal the existence of an older wall surface underneath which has been covered later in the due course of time [16][17][18]. Moreover, the comparison of different profiles coming from different chronological periods make it possible to see differences in practices over time.…”

Painted walls were analyzed at Ostia Antica, the ancient port of Rome, with the aim to trace the evolution of the buildings in the city. Nuclear magnetic resonance (NMR) depth profiles were acquired from walls and mortar fragments to image the stratigraphy of the mortar-layer preparations for the painted surfaces produced over more than five centuries from the 2 nd century BC to the 3 rd century AD. The profiles are compared to identify similar workmanship and contemporaneous origin, and to retrace the transformations of execution technique in time.

Relaxation in nuclear magnetic resonance (NMR), both transverse and longitudinal, provide information on microscopic features of a wide variety of systems and may be used to monitor dynamic processes such as cementation, chemical reactions, gelatinization, and evaporation. Dynamic relaxometry, in combination with spatial resolution, is a useful technique that provides deep insight into complex systems evolution. In this work, we explore the range of applicability of single-sided NMR to determine the evaporation kinetics of uid from porous media. We show that, due to technical experimental restrictions, the determination of the time-dependent amount of uid in different voids as a function of the position is in general not feasible with transverse relaxation experiments. However, as opposed to common intuition, longitudinal relaxation experiments provide reliable and fast acquisition, compatible with the requirements needed to monitor a water evaporation process from a model oil-reservoir rock sample.
