“…To this end, ToF-SIMS and XRFS techniques are applied, to extract useful information about the amount and the morphology of the surface contamination. XRFS are performed using an Olympus Delta Premium (INNOV-X) instrument to determine major and trace elements, as previously described [34]. The analyses can be performed on the polymeric samples non-destructively.…”

The presence of a weak remanence in Ultra-Low-Field (ULF) NMR sample containers is investigated on the basis of proton precession. The high-sensitivity magnetometer used for the NMR detection, enables simultaneously the measurement of the static field produced in the sample proximity by ferromagnetic contaminants. The presence of the latter is studied by high resolution chemical analyses of the surface, based on X-ray fluorescence spectroscopy and secondary ions mass spectroscopy. Methodologies to reduce the contamination are explored and characterized. This study is of relevance in any ULF-NMR experiment, as in the ULF regime spurious ferromagnetism becomes easily a dominant cause of artefacts.

“…Experts working on the conservation of cultural heritage have supported the use of non-destructive testing methods (NDT) in recent years [3], [4] because application of these techniques, structural stability and functionality are maintained without any intervention such as digging and drilling that disrupt the physical integrity [5], [6]. These techniques are used in order to identify archaeological assets buried under a heritage building [7]; determine the homogeneity, quality, or amount of deterioration of a building material [1], [8]; determine the morphology and cavities, moisture distributions, size of cracks; evaluate the injection made in the restoration of building elements [3]; observe the degree of damage to a building element damaged in an earthquake [5]; do origin analysis of archaeological artifacts [9], [10]; determine whether the gilding on the work is produced from real gold or another gold imitation material [11], [12], detect subsurface defects [13]; and investigate the compatibility of the original building material with the modern building material [14].…”

Analysis of cultural heritage by non-destructive testing methods allows conducting an examination of the building while preserving its authenticity and integrity, as well as its historical and artistic values. As the material of this study, the Sivas Congress Museum, which witnessed a very important event in the history of the country, was discussed. The aim of the study is to determine the stone type, deterioration, hardness, and strength of the building and thus generate an idea about the quality of architectural practices in the 19th century. In addition, it aims to create a scientific basis for conservation measures and restoration works to be carried out in the following years and to determine whether there is any difference between the stone material used in the main building and the stone of the building annexed later on. At the end of the study, it was concluded that the poor economic conditions of the country have affected the quality of the building material, the stones – soft and low-strength limestone – have been exposed to atmospheric pollution and deteriorated. In addition, although one of the stones that had undergone black crusting was cleaned, it was found that mechanical cleaning was insufficient to eliminate the pollution.
