2021
Abordamos en este trabajo la caracterización del personaje de Fadrique en la Philosophia Antigua Poetica y su identificación con el humanista valenciano Fadrique Furio Ceriol. A través de esta caracterización nos aproximaremos a los rasgos personales y vitales, sus actividades y participación en algún círculo literario en los últimos 10 años de su vida. In this work we address the characterization of the character of Fadrique in the Philosophia Antigua Poetica and his identification with the Valencian humanist Fadrique Furio Ceriol. Through this characterization we will approach his personal and vital traits, his activities and his proximity to a literary circle in the last 10 years of his …

P-C Cross-Coupling Onto Enamides: Versatile Synthesis of α-Enamido Phosphane Derivatives
2012
We report herein the Pd-catalyzed P–C cross-coupling reac- tion between enol phosphates and secondary phosphane–bor- ane complexes or phosphane oxides. The reaction was per- formed under mild conditions, owing to Pd activation of the P–H bonds of the phosphane–boranes (or phosphane oxides) and to the powerful enol phosphate coupling reagents. New useful chiral and achiral α - β -alkenylphosphane derivatives bearing an amido group in the α -position to the P center were obtained in yields up to 70 %.
Designing P-Chirogenic 1,2-Diphosphinobenzenes at Both P-Centers Using P(III)-Phosphinites
2016
International audience; A new enantiodivergent synthesis of P-chirogenic 1,2-diphosphinobenzenes (DP*B) bearing the chirality on one or both phosphorus centers is reported using aryne chemistry. The principle is based on successive reactions of 1,2-dibromobenzene with sec-phosphide boranes, then DABCO to remove the borane, and finally with chlorophosphines or P(III)-chirogenic phosphinites. The efficiency of this synthesis was demonstrated by the stereoselective preparation of (S,S)-1,2-bis(o-anisylphenylphosphino)benzene. A comparison of DIPAMP and homochiral DP*B ligands in asymmetric Rh- or Pd-catalyzed reactions was reported.
Surfactant-Mediated Morphology and Photocatalytic Activity of α‑Ag2WO4 Material
2018
In the present work, the morphology (hexagonal rod-like vs cuboid-like) of an α-Ag2WO4 solid-state material is manipulated by a simple controlled-precipitation method, with and without the presence of the anionic surfactant sodium dodecyl sulfate (SDS), respectively, over short reaction times. Characterization techniques, such as X-ray diffraction analysis, Rietveld refinement analysis, Fourier-transform (FT) infrared spectroscopy, FT Raman spectroscopy, UV–vis spectroscopy, transmission electron microscopy (TEM), high-resolution TEM, selected area electron diffraction, energy-dispersive X-ray spectroscopy, field emission-scanning electron microscopy (FE-SEM), and photoluminescence emission…
Il bisogno di fotografare. La fotografia nell’epoca delle immagini in digitale
2019
La proliferazione e l’ubiquità delle immagini pongono in maniera pressante la questione del loro senso e del tipo di esperienze cui danno luogo. Tuttavia la loro quantità, certamente eccessiva, non placa il bisogno che abbiamo di produrle, di condividerle e di sfruttare sino in fondo la loro capacità di rendere conto della contemporaneità. La fotografia è certamente una delle forme mediali che più ha contribuito alla costituzione di un ecosistema digitale. Ciò che è in gioco non è infatti semplicemente la natura delle immagini fotografiche ma più in generale la ristrutturazione del reale attraverso la mediazione del digitale. Il volume propone un’estetica della fotografia a partire delle pi…
Synthesis, characterization, and cellular investigations of porphyrin– and chlorin–indomethacin conjugates for photodynamic therapy of cancer
2021
Indomethacin is a potent non-steroidal anti-inflammatory drug (NSAID) with a strong selective inhibitor activity towards cyclooxygenase-2 (COX-2), an enzyme that is highly overexpressed in various tumour cells, being involved in tumourigenesis. Concomitantly, porphyrins have gained much attention as promising photosensitizers (PSs) for the non-invasive photodynamic therapy (PDT) of cancer. Herein, we report the design, and determine the singlet oxygen generation capacity and in vitro cellular toxicity of porphyrin- and chlorin-indomethacin conjugates (P2-Ind and C2-Ind). Both the conjugates were obtained in high yields and were characterized by 1H, 19F and 13C NMR as well as by high resolut…
Deepening Inside the Pictorial Layers of Etruscan Sarcophagus of Hasti Afunei: An Innovative Micro-Sampling Technique for Raman/SERS Analyses
2019
The Hasti Afunei sarcophagus is a large Etruscan urn, made up of two chalky alabaster monoliths. Dated from the last quarter of the third century BC, it was found in 1826 in the small town of Chiusi (Tuscany- Il Colle place) by a landowner, Pietro Bonci Casuccini, who made it part of his private collection. The noble owner&rsquo
High-Level Ab Initio Predictions of Thermochemical Properties of Organosilicon Species: Critical Evaluation of Experimental Data and a Reliable Bench…
2022
A high-level composite quantum chemical method, W1X-1, is used herein to calculate the gas-phase standard enthalpy of formation, entropy, and heat capacity of 159 organosilicon compounds. The results set a new benchmark in the field that allows, for the first time, an in-depth assessment of existing experimental data on standard enthalpies of formation, enabling the identification of important trends and possible outliers. The calculated thermochemical data are used to determine Benson group additivity contributions for 60 Benson groups and group pairs involving silicon. These values allow fast and accurate estimation of thermochemical parameters of organosilicon compounds of varying comple…
Recensione a L.B. Alberti, De pictura, a cura di L. Bertolini
2014
L’edizione della redazione volgare del De pictura curata dalla Bertolini inaugura la sezione «Trattati d’arte» dell’«edizione nazionale» delle opere dell’Alberti e costituisce in certo modo un primo tomo del volume che si completerà con la pubblicazione della redazione latina. La sequenza editoriale ripropone l’ordine cronologico che, secondo la tesi ripresa e riformulata da Lucia Bertolini nel 2000 e qui sviluppata in un’ampia premessa, vide nascere per mano dell’Alberti prima la stesura volgare e poi quella latina.
