Bright Circularly Polarized Electrochemiluminescence from Heterobinuclear IrIII–AuI Enantiomers
Get PDFThe development of efficient circularly polarized electrochemiluminescence (CP-ECL) probes is still at its infancy and examples are still very limited. Yet, their achievement would enable gathering a readout that carries privileged information on the probe's chiral environment by monitoring luminescence polarization bias with high signal-to-noise ratio. Notwithstanding, this is a highly challenging task and requires judicious chemical engineering of chiral ECL-active emitters. Herein, we aim at expanding the palette of CP-ECL luminophores by presenting a novel class of enantiopure heterobinuclear Ir(III)–Au(I) complexes, which are investigated thoroughly by means of chemical, structural, and (chiro-)optical techniques. The ground and excited state properties are also elucidated by using density functional theory (DFT) approaches including spin-orbital coupling (SOC) perturbation. The chiral-at-metal complexes display luminescence with a polarization bias of the emitted light that is function of the helical arrangement of the coordination sphere around the Ir(III) center. Overall, the photo- and electro-active complexes unraveled in this work combine unparallelly high photoluminescence quantum yield in the orange region, excellent circularly polarized luminescence (CPL) brightness up to 4.5 M−1 cm−1 with a notable ECL activity. Finally, these features provide emitters with CP-ECL efficiency that encompass remarkably by a factor 3.5 that of the well-known benchmark tris-(2,2′-bipyridyl)ruthenium(II)

Il sottotitolo dell’originale sottolinea che si tratta di testimonianze min dakhil Ghazza (“dall’interno di Gaza”), cioè scritte da palestinesi che vivono nella Striscia. Diffuse perlopiù dai social networks, sono riportate in ordine cronologico, coprendo un periodo che va dall’ottobre del 2023 fino al settembre 2024
Diari e miscellanee

Demon names, onomastic sequences, and incantation specialists in Mandaic incantations from late-antique Mesopotamia
No full textMandaic incantations on earthenware bowls and metal lamellae from Sasanian Mesopotamia (4th – 7th centuries AD) mention a profusion of demons that must be annihilated for the well-being of a client, his/her family, and possessions. Demons are frequently former Babylonian and Iranian gods and goddesses and their names are often arranged in lists. These lists derived from written Vorlagen that incantation specialists consulted to look for the formulas best suited to the case they had to tackle. This paper offers a preliminary investigation into some onomastic strategies employed by incantation specialists to characterise demons and to emphasise their behaviour and geographical location. These strategies include association with toponyms, wordplay, etymological figures, and detailed onomastic sequences
Constructive News Across Languages and Cultures
No full textConstructive news is an alternative to the negativity of if-it-bleeds-it-leads journalism but still unfamiliar to some audiences and still relatively under-researched, particularly by news translation scholars. And yet, it is “done” across cultures and, therefore, languages. This innovative book contributes to filling that research gap and raising awareness of the phenomenon by showcasing cross-cultural research on constructive news, including in the Global South – a region that has traditionally received less scholarly attention than the Global North. Constructive news is resolutely multimodal, and so a number of chapters analyse it from that perspective. The chapters also tackle such topics as audience attitudes, service to the local community, pedagogy, financial news, and religious news. This book will appeal to journalism studies and translation scholars, applied linguists, lecturers, journalists, editors, and members of the public who consume, study, or teach news but are looking for alternatives
Quod Caelum stet, Terra moveatur by Celio Calcagnini: Scientific Context and Translation
No full textThis paper offers an introduction to the Renaissance defence
of terrestrial motion by the Ferrara humanist Celio Calcagnini,
Quod caelum stet, terra moveatur (ca. 1518). It presents its
main argument and reconstructs its intellectual context. It
also comprises the first translation in English. This treatise
is an early document of the circulation of geokinetic
conceptions. It was written in the very years when the
revolutionary ideas of Copernicus started to circulate and
De revolutionibus orbium coelestium was taking shape.
Calcagnini’s defence of terrestrial motion especially drew
on natural and epistemological conceptions stemming
from humanistic eclecticism, influenced by scepticism and
Platonism. The paper also offers an interpretation of
celestial motions that Calcagnini attributed to the Earth,
although he did not expound on the mathematical details
In Conversation with Taina Syrjämaa
No full textThis paper presents an interview with Professor Taina Syrjämaa, a distinguished historian specialising in a wide range of fields including animal history, urban history, and the history of travel and tourism. In this brief structured interview, Professor Syrjämaa reflects on her doctoral research journey, which uncovered the central role ENIT in shaping Italy’s image abroad during the interwar period. Professor Syrjämaa shares her motivations, methodological challenges, and key findings, providing insights into Italy’s promotional strategies that emphasised cultural heritage over overt political messages, even during the Fascist regime

La costruzione del mito del 1054: fonti medievali e riletture, contemporane
No full textQuesto contributo analizza la costruzione e l’evoluzione del mito dello “scisma del 1054”, mostrando come un evento di portata limitata nel suo contesto storico sia stato reinterpretato nei secoli fino a diventare simbolo della frattura tra la Chiesa d’Oriente e quella d’Occidente. Alessandra Bucossi ripercorre le fonti medievali – dalle lettere dei protagonisti, Leone di Ocrida, Michele Cerulario, Leone IX e Pietro di Antiochia, ai documenti sinodali e ai trattati teologici – per distinguere i fatti dalle successive elaborazioni ideologiche. L’autrice evidenzia come il tema delle azzime, più che il Filioque, fosse al centro del dibattito dell’XI secolo, e come la memoria dello scisma sia stata plasmata nel XIII secolo, in particolare durante le trattative dell’Unione di Lione (1274), quando Cerulario fu trasformato nel simbolo della divisione tra Roma e Costantinopoli. Attraverso un’analisi diacronica, il capitolo mostra come un “non-evento” storico sia divenuto un potente mito teologico e politico, destinato a influenzare per secoli la percezione dei rapporti tra le due Chiese.This paper examines the construction and evolution of the myth of the “Schism of 1054,” showing how a limited historical event gradually became the symbolic moment of rupture between the Eastern and Western Churches. Alessandra Bucossi retraces the medieval sources—from the correspondence between Leo of Ohrid, Michael Cerularius, Leo IX, and Peter of Antioch, to synodal acts and theological treatises—in order to separate historical facts from later ideological elaborations. She demonstrates that the controversy over the use of unleavened bread, rather than the Filioque, was the true theological focus of the eleventh century, and that the memory of 1054 was shaped in the thirteenth century, especially during the debates surrounding the Council of Lyons (1274), when Cerularius came to embody the division between Rome and Constantinople. Through a diachronic analysis, the chapter reveals how a historical “non-event” evolved into a powerful theological and political myth that continued to shape the narrative of East–West relations for centuries
