We present the first validation and application of portable Sequentially Shifted Excitation (SSE) Raman spectroscopy for survey painted layers in art.
Here, we demonstrate, for the first time, extension of applicability recently developed microscale spatially offset Raman spectroscopy (SORS), micro-SORS, from area cultural heritage to a wider range analytical problems involving thin, tens micrometers thick diffusely scattering turbid layers. The method can be applied in situations where high turbidity layers prevents deployment conventional confocal microscopy with its depth resolving capability. was successfully detect noninvasively...
Cyclodextrin (CD)-based polymers are known to efficiently form molecular inclusion complexes with various organic and inorganic guest compounds. In addition, they also have a great potential as metal because deprotonated hydroxyls can strongly bind ions under alkaline conditions. The range of environmental conditions for polycyclodextrin/metal ion complexation be extended by the polymerization CDs polyacids. This article describes preparation characterization new type poly(β-cyclodextrin)...
Street art, and its preservation, has become one of the most discussed still open topics in field conservation. The absence a sharable conservation protocol terms cleaning protection is delicate subject to deal with. contemporary murals urban artworks stained by graphical vandalism real challenge, due similar chemical composition materials involved. In this work two different approaches street art murals, namely methods laser cleaning, are reported compared with aim identifying suitable...
Copper complexes with different ligands (ethylenediaminetetraacetic acid, EDTA, ammonium citrate tribasic, TAC, and alanine, ALA) were studied in aqueous solutions hydrogels the aim of setting optimal conditions for copper stain removal from marble by agar gels, damage minimization. The stoichiometry stability monitored ultraviolet-visible (UV-Vis) spectroscopy symmetry Cu(II) centers gel formulations was electron paramagnetic resonance (EPR) spectroscopy. Cleaning effectiveness optimized...
We present a method for estimating the thickness of thin turbid layers using defocusing micro-spatially offset Raman spectroscopy (micro-SORS). The approach, applicable to highly systems, enables one predict depths in excess those accessible with conventional microscopy. technique can be used, example, establish paint layer on cultural heritage objects, such as panel canvases, mural paintings, painted statues and decorated objects. Other applications include analysis polymer, biological...
This paper demonstrates the potentiality of high resolution micro-ATR-FTIR to reconstruct micrometric layers images.
Soluble salts content and their crystallization play an important role in the deterioration of porous substrates; common approach to solve this conservative problem is focused on identification a proper thickener application protocol able reach good level desalination. Here we report results systematic study late Renaissance plaster aimed at reducing gypsum sodium nitrates comparing five different type thickeners. The extractive process has been monitored by Evanescent Field Dielectrometry...
Abstract A dual-wavelength Q-switched Nd:YAG laser emitting at 1064 nm and 532 an Er:YAG were tested on a range of feathers containing melanin, carotenoids psittacofulvins. Dyed, white iridescent feathers, as well down also included in the study. First, damage threshold fluence was determined for each type feather then, appropriate, tests conducted artificially soiled with dust or carbon black. The unsuccessful cleaning Better outcomes obtained dust: effective both wavelengths removing from...
