Spectral imaging and archival data in analyzing the Madonna of the Rabbit painting by Manet and Titian

A concise insight into the outputs provided by the latest prototype of visible-near infrared (VIS-NIR) multispectral scanner (National Research Council-National Institute of Optics, CNR-INO, Italy) is presented. The analytical data acquired on an oil painting Madonna of the Rabbit by É. Manet are described. In this work, the VIS-NIR was complemented with X-ray fluorescence (XRF) mapping for the chemical and spatial characterization of several pigments. The spatially registered VIS-NIR data facilitated their processing by spectral correlation mapping (SCM) and artificial neural network (ANN) algorithm respectively for pigment mapping and improved visibility of pentimenti and of underdrawing style. The data provided several key elements for the comparison with a homonymous original work by Titian studied within the ARCHive LABoratory (ARCHLAB) transnational access project

Rubens' painting as inspiration of a later tapestry: non-invasive analyses provide insight into artworks history.

The 17th century painting Madonna della Cesta by Rubens and its presumed textile reproduction created by Févère for the House of Medici were analysed in comparison. A number of non-invasive optical techniques were applied with the aim to identify similarities and differences between tapestry and painting, in order to shed light on a possible link between their respective authors. The use of a multi-analytical approach proved effective for the acquisition of iconographic, morphological, structural, and compositional information for a comprehensive characterization of the two artworks. While serving as relevant support for documentation and conservation purposes, data so obtained also provide evidence of the uncanny resemblance between the two artworks, and specifically suggest the use by Févère of the same large-scale preparatory drawing (carton) realized by Rubens for his oil painting.Fil: Dal Fovo, Alicia.

Synchronized Hardware-Registered VIS-NIR Imaging Spectroscopy and 3D Sensing on a Fresco by Botticelli

We discuss a synchronised sensing technique for the analysis of painted surfaces of frescos. Specifically, the performance of Visible-Near Infrared (VIS-NIR) Reflectance Imaging Spectroscopy (RIS) synchronized with three-dimensional (3D) acquisition is demonstrated in the study of a detached mural painting by Alessandro Botticelli. Synchronized sensing generates georeferenced data for simplified data treatment and interpretation. We show how such output data can provide key information to interpret important fresco surface and subsurface features (e.g., painting technique, material composition, pentimenti)

Titania-decorated hybrid nano-architectures and their preliminary assessment in catalytic applications

Gold nanomaterials have been recognized as considerably active and effective catalysts toward several industrial and environmentally relevant reactions, among which are hydrocarbon selective oxidation, CO oxidation and propylene epoxidation. Engineered nanomaterials may be able to suppress some of the more severe issues that block their industrial applicability, such as recyclability, catalytic activity reduction during time due to sintering effects or leakage of the active material. In this regard, the composition of hybrid nanomaterials comprising encapsulated ultrasmall gold nanoparticles, also called ultrasmall-in-nano, will broaden and enhance their potential catalytic applications by including synergic features. Here, we report a systematic investigation on the design and production of optimized titania-decorated gold nano-architectures together with their efficiency evaluation on both formic acid (thermo/photo-induced) decomposition and cyclic carbonates formation by carbon dioxide fixation for carbon capture and storage technology. This work paves the way for the next development of ultrasmall-in-nano catalysts bearing an early–late transition metal combination for sustainable processes

Mani pensanti e teste operose: bambini, bambine, educatori e insegnanti verso l'orizzonte 2020

Nel corso degli anni diverse sono state le rappresentazione del modo di funzionare della mente umana, tali da influenzare le azioni e gli interventi educativi, soprattutto nei primi anni di vita. Attualmente si va verso una riscoperta del ruolo del corpo, dell'azione e delle percezioni come fonte di apprendimento, sia esso informale, non formale o anche formal
