The Conference will be held in Cadiz over three days, from 21 to 24 May 2017. During the Conference, Cadiz, which is one of the oldest cities in Western Europe, and preserves an important historical legacy, becomes a unique scenario for discussions on all aspects of Cultural Heritage. A high-quality scientific programme has been prepared, which includes new emerging topics on Cultural Heritage such as: nanotechnology, innovative monitoring and characterisation techniques, and 20th century Cultural Heritage preservation. I would like to thank you for your scientific contribution and your attendance, which will assist in increasing the overall scientific quality of the Conference. The response to TechnoHeritage 2017 has been overwhelming. Over 200 communications of high scientific quality, from 23 different countries, will be discussed during the three days duration of the scientific programme. I am also happy to announce the special session: “Biodeterioration: Fundamentals, present and future perspectives, a session in honour of Prof. Cesáreo Sáiz Jiménez”, who recently retired. Our intention is to recognise Prof. Sáiz Jiménez’s work and its impact on the Cultural Heritage conservation community, which he has helped to promote through numerous activities including, in 2011, the creation of the TechnoHeritage network. Finally, I would like to offer special thanks to the Local Organising Committee, the International Advisory Board, and the companies and institutions participating as sponsors, for their much appreciated efforts in making this international scientific event a success. I hope you enjoy your stay in Cadiz, and that you experience a truly valuable and memorable Conference. María J.

Baglioni Department of Chemistry “Ugo Schiff”, University of Florence, and CSGI-Florence, Sesto Fiorentino, Florence Italy [email protected] Colloid and surface Science has always been central disciplines in many applicative areas, and fundamental knowledge from colloids has been applied across a range of industries as pharmaceutical, detergency, paint, and food industries. A precise control on structure and dynamics of colloids is required to transfer a laboratory-scale know how to field applications. This will be even truer in the near future, with the development of sophisticated hierarchically organized systems, where single components combine in a synergistic or orthogonal way to provide enhanced performances for the intended end-applications. The Florence group has pioneered the application of soft matter and materials science to several fields, one of the most exotic is the conservation of cultural heritage that was pioneered by us. In this field, the same tenets as for the above- mentioned applicative areas hold. Art Conservation poses a formidable and exciting challenge to Colloid and Interface Scientists in two respects. First, the majority of the most performing and environmentally-safe cleaning and consolidation agents for artworks are soft matter systems. Second, the interaction of these agents with the artifact involves an exceptionally complicated range of interfacial interactions. In this lecture I will review the most meaningful achievements of my group in this field, focusing on the application of colloidal dispersions of increasing complexity, from nanoparticles to o/w microemulsions to semi-interpenetrating hydrogels containing o/w microemulsions. These systems have been used on artifacts of the most diverse origins, from Renaissance frescoes to Picasso and Pollock. I will show how chemical and colloidal design can be implemented to meet the requirements of the end-users and how precise knowledge of structure, dynamics and interfacial interactions can contribute to overcome the traditional serendipitous approach used by conservators. Finally, I will try to summarize the main perspectives that this field can disclose for Chemistry and conservators communities.

Rathousky J. Heyrovsky Institute of Physical Chemistry (Academy of Sciences of the Czech Republic) Dolejskova 3, 182 23 Prague 8, Czech Republic [email protected] Since early 2000s Baglioni, Dei et al. has pioneered the use of micellar solutions and microemulsions for cleaning artworks, especially for the selective removal of aged polymeric coatings from the surface of wall paintings. Inspired by their work, we have developed a generalize method, which enables to selectively remove a broad range of target substances from the surface of materials. Our approach is based on the combination of two functions which are realized by two components - the “standard” micellar solution or microemulsion of nonionic surfactants with co- surfactants added, which is practically the same for various target substances (such as oils, waxes, polymers), - the specific solvents selected according to the respective substance to be
