Solid State Nuclear Magnetic Resonance spectroscopy (SSNMR) is today one of the most powerful techniques for characterizing solid and soft materials and systems. This spectroscopy allows the detailed characterization of structural and dynamic properties over large spatial (0.1-100 nm) and time (102-10-11 s) scales. Accessing these properties allows a deep knowledge of a material to be obtained and its design and optimization to be oriented. The "probes" used in SSNMR are the nuclei of the chemical elements naturally present in the analyzed systems, distributed along the Periodic Table. Examples of relevant properties/processes that can be determined by SSNMR are: chemical and supramolecular structure, interactions between atoms and molecules, degree of mixing and interactions between the different components, phase properties and polymorphism, amorphous phases, transformations, hydration, degradation, molecular motions.
SSNMR combines great power with extraordinary versatility. It allows the analysis of almost every type of solid or semi-solid, crystalline, amorphous or semi-crystalline, organic, inorganic or hybrid material / system, directly in its state of use (powders, films, fibers, ...), without any pre-treatment. The possibility of observing chemical elements naturally present in the sample and a very large "library" of experiments allow the characterization of even very complex materials. Examples of sectors of successful application are pharmaceutics, biomedicine, energy transition, circular economy, construction, technology, catalysis. SSNMR requires dedicated, complex and expensive instrumentation and highly specialized know-how. Our group has a thirty years lasting experience in the sector and can count on an innovative instrumentation, which is currently the most complete and advanced in Italy for the study of materials.
