Un monastero per due Ordini: il SS. Salvatore di Corleone
2019
Al patrimonio figurativo, plastico e scultoreo della chiesa del SS. Salvatore di Corleone per lo più ormai noto da annotazioni bibliografiche o documentarie si aggiunge quello altrettanto ricco di arte decorativa. Di quest’ultimo, nonostante le numerosissime dispersioni, si individuano importanti opere, alcune delle quali esposte alla Mostra Sacra et pretiosa In addition to the figurative, plastic and sculptural heritage of the church of SS. Salvatore di Corleone, mostly known from bibliographical or documentary annotations, there is also a wealth of decorative art. Of the latter, despite the numerous dispersions, there are important works, some of which are exhibited at the Mostra Sacra et…
Reactivity of antitumor coinage metal-based N-heterocyclic carbene complexes with cysteine and selenocysteine protein sites
2021
Abstract The reaction of the antitumor M(I)-bis-N-heterocyclic carbene (M(I)-NHC) complexes, M = Cu, Ag, and Au, with their potential protein binding sites, i.e. cysteine and selenocysteine, was investigated by means of density functional theory approaches. Capped cysteine and selenocysteine were employed to better model the corresponding residues environment within peptide structures. By assuming the neutral or deprotonated form of the side chains of these amino acids and by considering the possible assistance of an external proton donor such as an adjacent acidic residue or the acidic component of the surrounding buffer environment, we devised five possible routes leading to the binding o…
Green and Integrated Wearable Electrochemical Sensor for Chloride Detection in Sweat
2022
Wearable sensors for sweat biomarkers can provide facile analyte capability and monitoring for several diseases. In this work, a green wearable sensor for sweat absorption and chloride sensing is presented. In order to produce a sustainable device, polylactic acid (PLA) was used for both the substrate and the sweat absorption pad fabrication. The sensor material for chloride detection consisted of silver-based reference, working, and counter electrodes obtained from upcycled compact discs. The PLA substrates were prepared by thermal bonding of PLA sheets obtained via a flat die extruder, prototyped in single functional layers via CO2 laser cutting, and bonded via hot-press. The effect of co…
[Fe(TPT)(2/3){M(I)(CN)2}2]⋅nSolv (M(I) = Ag, Au): new bimetallic porous coordination polymers with spin-crossover properties.
2013
Two new heterobimetallic porous coordination polymers with the formula [Fe(TPT)2/3{MI(CN)2}2]¿nSolv (TPT=[(2,4,6-tris(4-pyridyl)-1,3,5-triazine]; MI=Ag (nSolv=0, 1¿MeOH, 2¿CH2Cl2), Au (nSolv=0, 2¿CH2Cl2)) have been synthesized and their crystal structures were determined at 120¿K and 293¿K by single-crystal X-ray analysis. These structures crystallized in the trigonal R-3m space group. The FeII ion resides at an inversion centre that defines a [FeN6] coordination core. Four dicyanometallate groups coordinate at the equatorial positions, whilst the axial positions are occupied by the TPT ligand. Each TPT ligand is centred in a ternary axis and bridges three crystallographically equivalent Fe…
Il tesoro della Matrice di Regalbuto tra Settecento e Ottocento
2012
The essay proposes a scientific study of the silverware of the Treasure of the Mother Church of Regalbuto made between the eighteenth and nineteenth centuries, framing them in the historical-artistic context of the time.
Aportaciones documentales sobre cruces de orfebrería valencianas. Siglos XIV y XV
2020
The article intends to make a contribution of new documentary references, from the notarial funds of the Valencian archives, in which news about parish crosses and Lignum Crucis from the silversmith center of Valencia during the fourteenth and fifteenth centuries are collected. The importance of these typologies lies in being the main elements of Christian worship, so it was an essential piece in each parish that allowed the provision in them of models of varied typology and functionality; for that reason they are conserved from altar crosses, cross-shaped reliquaries ?known as Lignum Crucis or Veracruz ?to processional crosses, larger and representative of the parish community to which it …
Exploring the self-assembly of resorcinarenes : from molecular level interactions to mesoscopic structures
2012
Unprecedented use of silver(I) N-heterocyclic carbene complexes for the catalytic preparation of 1,2-bis(boronate) esters.
2005
Catalytic diboration of internal and terminal alkenes with Ag(I) N-heterocyclic carbene complexes leads to 1,2-bis(boronate) esters as single intermediates, that can be oxidised towards the corresponding diols. Sanau Torrecilla, Mercedes, Mercedes.Sanau@uv.es
I Ventimiglia e le arti decorative a Lascari
2016
Il saggio, attraverso l'analisi di inedite fonti archivistiche, delinea la committenza di alcuni membri della famiglia Ventimiglia per Lascari e la sua chiesa parrocchiale dalla fine del XVII secolo ai primi decenni del XIX. Gli esponenti della nobile stirpe per la realizzazione di tali opere, alcune delle quali ancora custodite, si rivolgevano perlopiù ad artisti palermitani, tra cui l'abile marmorario Domenico Magri. The essay, through the analysis of unpublished archival sources, outlines the patronage of some members of the Ventimiglia family for Lascari and its parish church from the end of the 17th century to the first decades of the 19th century. The exponents of the noble lineage fo…
Etude du comportement alimentaire des enfants ayant un syndrome de Silver-Russell
2014
National audience; Introduction et but de l’étude. – Le syndrome de Silver-Russell (SSR) est une maladie épigénétique rare caractérisée par un retard de croissance intra-utérin avec périmètre crânien relativement préservé, une petite taille post-natale associée à une dysmorphie et une asymétrie corporelle inconstante. Des difficultés alimentaires majeures sont souvent décrites pouvant nécessiter le recours à une nutrition entérale prolongée. À ce jour, aucune étude n’a décrit précisément les troubles du comportement alimentaire de ces enfants. Le but de notre travail était donc de caractériser les différentes composantes du comportement alimentaire d’enfants ayant un SSR. Matériel et méthod…
