Abstract Most of the Cultural Heritage built in NW Iberian Peninsula is made of granite which
exposition to the environment leads to the formation of deposits and coatings, mainly two …

This review aims to look at the development of Raman spectroscopy as applied to the field of
cement science. Starting with a historical overview, it then considers the spectra of cements …

This article investigates the impact of sulfur dioxide attack, deposition of dark particles in
urban environments and laser cleaning with Nd: YAG 1064 nm on color change in a range …

In the last twenty years lasers have acquired an important role in the study and the
preservation of Cultural Heritage (CH) objects and Monuments, as they have effectively …

Concrete surfaces were studied by two spectroscopic techniques, FT‐IR (in ATR mode) and
Raman, to establish a nondestructive method to analyze the distribution of hydrated and …

Hypothesis The removal of over-paintings or graffiti is a priority for conservators and
restorers. This operation is complex, especially when over-paintings lay on painted surfaces …

In the context of this work, a prototype hybrid photoacoustic (PA) and optical system for the
on-line monitoring of laser cleaning procedures is presented. The developed apparatus has …

The laser cleaning process combined with laser-induced breakdown spectroscopy (LIBS)
were applied to restore and characterize altered limestones of the ancient jamb of the …

This paper addresses the evaluation of the cleaning of crustose lichens developing on
granite. The evaluation was performed considering the effectiveness of the cleanings and …

In the present work the pollutant content of diverse building materials was evaluated by the
combination of spectrometric and chromatographic techniques. A first non-destructive …
