Materials for the conservation of stone substrates.
Study of new materials for the protection and/or consolidation of natural and artificial (e.g. mortars, bricks) stone substrates. Application of protecting and/or consolidating agents on laboratory specimens as well as in situ to evaluate their performances by using standard tests and protocols. Use of multi-technique procedures to investigate the treated substrates.

Nanoparticles in the conservation techniques.
Preparation and investigation of inorganic nanoparticles, their surface functionalization (when appropriate) and application to the protection and consolidation of stone and wood artifacts. Assessment of the performances displayed by plain nanoparticles and by organic/inorganic hybrid materials obtained from proper combination of nanosized inorganic materials with organic matrices.

Diagnostic protocols for cultural heritage items.
Development of analytical protocols based on micro- as well as non-invasive techniques for the characterization of works of art and the assessment of their state of conservation, particularly concerning historic musical instruments.

New techniques for the works of art cleaning.
Development of new materials and methods for the cleaning of stone and wood cleaning by particularly using gels based on products of plant origin and/or synthetic polymers.
