Low-field NMR for multi-scale characterisation of materials: from paintings to textiles<\/h1>\n<\/div>\n<\/div><\/div><\/div><\/div><\/section>

Abstract:<\/strong><\/h2>\n
Low-field nuclear magnetic resonance (NMR) has become a versatile tool for investigating the structure and dynamics of complex materials. During my PhD, I used unilateral NMR to study water dynamics and phase behaviour in historical paint systems during drying and ageing processes, bridging chemistry, materials science and cultural heritage studies. This work revealed how low-field NMR can provide non-invasive, quantitative insights into multi-phase materials with strong spatial heterogeneity.
In my current postdoctoral project, I apply similar NMR methodologies to a different class of materials, textiles, in order to explore transport and relaxation phenomena at multiple scales. The aim is to clarify the mechanisms involved in everyday situations such as washing and drying clothes. This approach highlights how low-field NMR can be used to probe fundamental physicochemical processes across a wide range of materials and applications.
I will present an overview of this research trajectory, introduce key NMR methods used for multi-scale characterisation, discuss current challenges in the ongoing work, and outline future perspectives for combining experimental and modelling approaches.<\/div>\n

Floriane Gerony is currently a postdoctoral researcher at Laboratoire Navier in the RMP team, working with Philippe Coussot. Since March 2025, she has been studying water transfers in textiles using low-field NMR relaxometry. She completed her PhD at Sorbonne Universit\u00e9 between the Laboratoire d\u2019Arch\u00e9ologie Mol\u00e9culaire et Structurale (LAMS) and the Laboratoire de Physicochimie des \u00c9lectrolytes et des Nanosyst\u00e8mes Interfaciaux (PHENIX), under the supervision of Maguy Jaber and Guillaume M\u00e9riguet. Her doctoral research focused on the properties of egg tempera paint, investigating its drying and ageing processes through low-field NMR relaxometry and FTIR spectroscopy. Previously, she completed an internship at the Centre de Recherche et de Restauration des Mus\u00e9es de France (C2RMF), where she worked on the identification and reconstruction of coloured materials in historical glazes.<\/p>\n
