DOW Description of work

NANOMATCH Nano-systems for the conservation of immoveable and moveable poly-material Cultural Heritage in a changing environment

SME Small and medium-sized enterprise

WP Work package

Introduction

The changing environment is producing a different kind of damage on cultural heritage in all Europe, so that the risk of impact on European cultural heritage will increase. NANOMATCH will help to find the best solutions to slow down the damage process and provide tools to mitigate the incoming new mechanisms of deterioration. There is an increasing necessity to share scien-tific knowledge for the protection and conservation of cultural heritage at the European level, in particular at a time when the environment is changing, also as a consequence of political management. For this reason, it is essential to disseminate and promote the results of scientific studies reached within the project.

The main objective of WP6 Dissemination is to make the broad field of conservation profes-sionals, industry and owners aware of the project, also involving SMEs in the research, produc-tion and marketing of innovative products for the conservation of built heritage. This will be achieved through the development of an awareness and dissemination plan which will establish by means of website, leaflet, newsletters, target audiences and other dissemination actions, like training, workshops and conferences.

1 Leaflet

The aim of the leaflet is to raise the awareness of NANOMATCH project to scientists, to stake-holder and to end-user all over Europe and beyond.

The text based mainly on the DOW, combined with meaningful pictures from the partners.

A first draft of the leaflet was prepared by Fraunhofer ISC and was presented to all partners at the project meeting in April 2012 in Istanbul. Based on this feedback the final version of the leaflet was prepared, agreed by the co-ordinator and finally printed.

1.1 Structure of the leaflet

The brochure consists of eight A4 pages (see Annex A), printed on the front and back of two sheets of A3 paper and folded together in the middle.

1.1.1 Title page

All relevant information are present at the front page: There is the NANOMATCH logo, the logo of FP7 next to the European Union flag, the full title of the project and the name of the web-page. In addition, it is mentioned that this is an “EU-FP7 Supported Project: Grant Agreement No 283182” and information about the EU research project and the European Commission is given.

1.1.2 Project description

Government authorities, restoration architects and conservation scientists have been confront-ed for many years with the problem of the deterioration of historic building materials, in par-ticular stone, wood and glass. This issue has become increasingly urgent as climate change and atmospheric pollution are worsening the effects of natural weathering, whilst socio-economic realities are requiring a more sustainable management of the built heritage. Furthermore, the current use of inappropriate commercial treatment products, especially polymers that were designed for purposes completely other than cultural heritage conservation, has had detri-mental effects on historic materials in recent years due to the fast deterioration of these prod-ucts that impacts the treated materials. Combining the most recent advances in the fields of nanotechnologies and conservation sci-ence, the NANOMATCH project will address these issues by developing a new class of innova-tive nano-structured materials, tailored specifically to historic materials and adapted to a cli-mate change context. They will provide enhanced sustainability, compatibility and efficiency compared to conventional conservation products, thus offering a real alternative and renewing the market dedicated to the conservation of the built heritage.

Alkaline earth and semi-metal alkoxides molecular precursors will be synthesised tuning their properties to the characteristics of the substrate to be treated and to the specific demands of their required function. The nano-coating deposition of these precursors in the historic ma-terials will lead to nano-structured conservation products compatible with the main built herit-age materials: stone, wood (including polychrome materials) and glass.

The products will be first assessed in the laboratory and then evaluated in the field through four different cases studies in Cologne, Florence, Bucharest.

The metal-alkoxides showing the highest performance and safety among the molecular precur-sors, also in comparison to commercial products, will be assessed for their introduction to the market. In the different steps of the project, the hazard impact of the metal-alkoxides on envi-ronment and human health will be monitored during the production and after the conservation treatments due to the possible environmental release of nanoparticles from the treated sub-strates by considering the transformation that the composts could undergo.

The best processing parameters for industrial production will be defined and the costs and benefits of the new products in economic terms will be determined. An exploitation plan, cen-tred on SME interests, leading to a business model will be also developed with an evaluation of the risk during the production/dissemination and exploitation in the market.

Overview of the new Materials

NANOMATCH will develop two conservation products: a new alkaline earth alkoxide product for stone and wood will be created and an already existing aluminium alkoxide product for glass. (EU project Constglass) will be optimised.

Stone and Wood

Within the bilateral French-Italian Project Galileo 2009, preliminary feasibility tests performed on limestone and wall paintings demonstrated that selected calcium alkoxides react with the atmosphere to produce calcium carbonate, identified by XRD measurements as calcite and vaterite. Depending on the experimental conditions, the vaterite/ calcite ratio identified in the final calcium carbonate varies considerably, underlining the importance of the solvent-dispersion agent interactions and the role of the substrate. Moreover, impregnation of a po-rous substrate, simulating a deteriorated stone, with a solution of calcium methoxide produces a crystalline nano-structured calcium carbonate film which is deposited on the surface of the substrate grains with a good adhesion, without cracks or formation of ungrafted particles. Unlike silica coating created by traditional consolidants like TEOS, this film homogeneously penetrates all the substrate pores, binding its grains together, thus fulfilling the primary re-quirements of a consolidant. Furthermore, non-destructive measurements showed that this coating increases the stone cohesion by 20% while, thanks to its nano-dimensions, it affects neither its surface appearance nor its water vapour permeability.

Glass

A molecularly dispersed aluminium alkoxide complex (A18) was developed during the EU pro-ject Constglass. Its promising properties as a glass consolidant are due to its very low viscosity that allows it to penetrate into the smallest capillaries of the corroded glass. After the solvent evaporation, the micro porous residue consists of an aluminium oxide precursor which subse-quently hydrolyses very slowly leading to an oxide network chemically bonded tightly to the inner walls of the cracks. This newly formed micro porous oxide network provides a guiding structure that is gradually filled in by glass components migrating from the vicinity of the crack, creating a new glass matrix within the crack, thus healing the corroded glass.

The NANOMATCH project aims at renewing the conservation product market by developing new, advanced, compatible and sustainable nano-structured consolidants as an alternative to conventional products, thus improving the preservation of Europe’s valuable built heritage.

1.1.3 Case studies

1.1.3.1 Cologne Cathedral

The Cologne cathedral is the one of the outstanding examples of Gothic architecture and has been added to the UNESCO World Heritage list in 1996. Its construction started in 1248 but it was only completed in 1880 after an interruption of several centuries. The main building material of the cathedral is trachyte stone but sandstone, shell-limestone and basalt have also been used. It possesses numerous stained glass windows, several internal wooden structures (choir stalls, historical confessionals) and many polychrome wooden sculp-tures. The church is situated in the heart of the city, near a railway station, and over the years weather, air pollution and micro-organisms have deteriorated the exterior materials.

Interior materials are also under environmental stress caused in part by the 5 millions annual visitors who bring with them dust, soil and humidity and light millions of candles.

1.1.3.2 Opera di Santa Croce, Florence

The basilica of Santa Croce, founded in 1294, is one of the finest Gothic churches in Italy and the largest Franciscan church in the world. It belongs to a monumental complex situated in the historic centre of Florence which was declared a World Heritage site in 1982. This complex has lived through a succession of religious, artistic and civic vicissitudes and its construction has been carried out over seven centuries. The Santa Croce basilica contains numerous masterpieces, in particular, the side chapels con-tain outstanding 14th c. Florentine paintings, including exceptional frescoes by Giotto, as well as masterpieces of 15th c. sculpture. Santa Croce also houses the funeral monuments of Mi-chelangelo, Galileo, Machiavelli and many other illustrious personages.

With the unification of Italy in the 19th c., it became a place of celebration of the national glory.

1.1.3.3 Stavropoleos Monastery, Bucharest

The Stavropoleos monastery lies at the heart of Bucharest and was founded in 1724. Of the original buildings, only the church, an outstanding example of the Romanian Brancovan style, has been preserved and contains a wealth of stone carvings, stucco-work and frescoes.

1.1.3.4 Cathedral of Oviedo

The cathedral of San Salvador of Oviedo is the most outstanding Gothic work in the Asturias region of Northern Spain. It was essentially built from the end of the 13th c. to the second half of the 16th c. and consequently, it illustrates the different stages of the Spanish Gothic’s evolu-tion. Baroque and Renaissance elements were later added. The current building rises around the pre-Romanesque and Romanesque Holy Chamber which was declared a World Heritage site by the UNESCO in 1988. It houses the cathedral treasure, including several relics that made Oviedo a regular and almost compulsory pilgrim stop on the road to Santiago de Compostela since the Middle ages.

The cathedral is built using two local limestones, the dolomitic “Laspra” stone, more porous and easier to carve, found in the cloister and the interior and exterior sculpted decoration, and the coarser “Piedramuelle” limestone, more durable, used for the building exterior. The humid climate of the Asturian region and the urban pollution of Oviedo have deteriorated these cal-careous stones, the Laspra stone more severely, leading to the decay of figures and ornaments.

Past consolidation treatments have proven unsuccessful and new conservation solutions are urgently needed.

1.1.4 Final page
