This ebook provides novel functions of nanotechnology for the upkeep of creative and historic artifacts. It explains the medical ideas in the back of various nanomaterials and discusses their purposes to forms of universal movable and stuck creative substrates. It starts off with an outline of the nano-tools constructed over the past 3 a long time, equivalent to dispersions of nanoparticles, micellar strategies, microemulsions and gels. in comparison to conventional tools, those new instruments get pleasure from significantly much less influence on either the operators and the surroundings. each one bankruptcy is devoted to a selected kind of cultural history fabric (wall and easel work, stone, paper, canvas and wooden) beginning with the most degradation paths and discussing protocols for the appliance of leading edge nanomaterials-based instruments for cleansing, consolidation, or deacidification, which symbolize nearly all of the case experiences encountered in recovery amenities, workshops and ateliers. The publication offers step by step descriptions that are supposed to aid conservators within the program of those novel fabrics and strategies. the purpose of the publication is to equip end-users and conservators with crucial details and data at the availability and applicability of alternative nano-materials and dispersed structures. whereas the book’s concentration is at the useful elements, readers also will locate references to the correct complex colloid and fabric technology literature.

Main viewers: professional conservators, restorers and technical employees at conservation institutes and museums, scholars at conservation and recovery colleges, and scientists who're new to the sphere of conservation of inventive and historic artifacts.

Sample text

EDX analysis showed an increase content in calcium in the plaster surface layers, confirming that penetration of the Ca(OH)2 nanoparticles had occurred, and water absorption tests highlighted that the wall porosity and water exchange capacity had not been altered by the treatment. The same formulation was applied to eighteenth century mural lunettes belonging to the Saint Jude and Simon cloister in Corniola (Empoli—Florence, Italy). The lunettes exhibited lacunas and powdering of the painted layer.

However, this methodology has proved effective also on carbonate-based secco paintings, and to some extent on stone, as described in the previous sections. The proposed method is based on the theoretical and practical knowledge gathered in the last decades through both research work and field activity in collaboration with conservators. It is fundamental to recall that each case study exhibits specific characteristics and issues; therefore the practical guidelines introduced here should be considered and applied critically, and not as recipes.

4). It is interesting to notice that upon drying, the particles tend to pile along the basal face (the {001} plane) as evidenced by XRD. In this way, particles form layers within the porous matrix of the substrate, and then undergo carbonation forming the CaCO3 network that provides consolidation. Later, Nanni and Dei (2003) carried out the synthesis of Ca(OH)2 nanoparticles in water-in-oil (w/o) microemulsions where the oil phase was cyclohexane. Two w/o emulsions are mixed, containing respectively Ca2+ and OH− ions in the dispersed water droplets.
