Estudos preliminares para consolidação de suportes com pintura mural: síntese e caracterização de nanocais

-Resumo Neste trabalho apresentam-se os resultados da síntese e da caracterização de nano-materiais de hidróxido de cálcio e de hidróxido de magnésio visando a sua aplicação como consolidantes de suportes com pintura mural. Este estudo preliminar constitui a etapa inicial de um projeto em curso e que tem como principal objetivo o desenvolvimento de novas estratégias de síntese de nano-materiais inovadores para conservação e restauro de revestimentos antigos. - Abstract In this publication, we report the synthesis and characterization of calcium and magnesium hydroxides nanoparticles for consolidation of mural paintings. Some preliminary results are discussed. This research is the initial part of our ongoing project which aims to develop new synthetic strategies towards novel and innovative materials for preservation and restoration of old rende

Novos desenvolvimentos para a deteção de leveduras e bactérias presentes em argamassas

The development of simple and rapid new approaches for analysing microbial communities colonising Cultural Heritage materials is pivotal for its safeguard. Fluorescence in situ hybridisation technique using ribosomal RNA directed probes (RNA-FISH) has demonstrated a great potential for this purpose. A protocol for analysing filamentous fungi in mortars has been already developed in previous studies. In this work this protocol has been adapted for detecting bacteria and yeasts. Good results have been obtained for the analysis of suspensions of isolates. In this way, the optimized protocol was applied in microsamples from synthetic mortar artificially inoculated with yeast and bacterial isolates. Promising results have been obtained for the ex situ analysis of yeast and bacteria thriving in mortar microsamples.

Reconstituição histórica virtual do retábulo-mor da Igreja do Espírito Santo de Évora: aplicação ao Património da infografia web-based

As a part of a multidisciplinary and integrated research, including conservation sciences and history, a proposal is presented for the historical reconstitution and the virtual restoration of the mannerist altarpiece of the main altar at the Espírito Santo Church, in Évora. The collected data is abundant and the scientific information, because of its technicality, is less prone to be easily understood by the general public, thus becoming less accessible. Web-based infographics are explored as privileged forms of disseminating results and raising awareness to Cultural Heritage. The project materializes as an Internet platform where data and a reconstitution proposal are shared in a visual and interactive way. In addition to the digital virtual reconstitution (2D), some tridimensional models (3D) are presented of various elements of the altarpiece, obtained using methods of computer graphics and digital photogrammetry
