Excited states engineering enables efficient near-infrared lasing in nanographenes

2021

The spectral overlap between stimulated emission (SE) and absorption from dark states (i.e. charges and triplets) especially in the near-infrared (NIR), represents one of the most effective gain loss channel in organic semiconductors. Recently, bottom-up synthesis of atomically precise graphene nanostructures, or nanographenes (NGs), has opened a new route for the development of environmentally and chemically stable materials with optical gain properties. However, also in this case, the interplay between gain and absorption losses has hindered the attainment of efficient lasing action in the NIR. Here, we demonstrate that the introduction of two fluoranthene imide groups to the NG core lead…

Uniform nanoporous graphene sponge from natural polysaccharides as a metal-free electrocatalyst for hydrogen generation

2019

[EN] Structuring of graphene as graphene sponges in the submicrometric scale has been achieved by using silica spheres (80 nm diameter) as hard templates and chitosan or alginate as precursor of defective N-doped or undoped graphene, respectively. The resulting defective N-doped graphene sponge exhibits a remarkable activity and stability for hydrogen evolution reaction with onset at 203 mV for a current density of 0.5 mA cm(-2) with a small Tafel plot slope of 69.7 mV dec(-1). In addition, the graphene sponge also exhibits a high double layer capacitance of 11.65 mF cm(-2). Comparison with an analogous N-doped graphene sample shows that this electrochemical properties derive from the spati…

Conversos, vescovi e inquisitori tra Spagna e Sicilia (secc. XV-XVII)

2022

La vasta geografia della Monarchia spagnola degli Asburgo è ormai da tempo considerata uno spazio storiografico di grande interesse, all’interno del quale si incrociano fenomeni tanto di integrazione o esclusione di gruppi sociali e religiosi, come nel caso dei conversos, quanto di circolazione di prelati impegnati nel controllo delle istituzioni ecclesiastiche, come vescovi e inquisitori. La Sicilia fu parte integrante di questo “scambio” di gruppi e individui, che con il sostegno delle rispettive reti familiari e clientelari contribuirono alla costruzione del composito e policentrico impero spagnolo. The wide geography of the Spanish Monarchy under Habsburgs’ rule has long been considered…

Alienation and nihilism in the “affluent society”: the topicality of Augusto Del Noce

2021

Del Noce’s thought unravels over several decades on the stimulation of the great historical events in the 20th century (Totalitarianism, the Second World War, the Cold War, the Second Vatican Council, the Historic Compromise in Italy, etc.). Del Noce tackles the major philosophers of his time in this long journey of meditation: from Maritain to Gilson, from Gentile to Gramsci, from Löwith to Lukács and from Voegelin to Croce, not forgetting the dialogue with the classics from Descartes to Rosmini, and Marx to Gioberti. In this paper, I will concentrate mainly on his reflections around the so-called “affluent society” where he has gathered together, prophetically, those nihilist and anti-Chr…

Nilde Iotti e i cristiani di sinistra: confronti di idee, momenti di storia

2021

The political commitment of Nilde Iotti, president of the Chamber of Deputies for three legislatures, provides an opportunity to compare the political ideas of Catholics and Communists during the Resistance and in the first decades of the Italian Republic. This comparison highlights that freedom and work are the fundamental elements of Italian democracy in the second half of the twentieth century.

The World of Anglo-Saxon Learning

2007

D uring the Anglo-Saxon period, English schools were among the finest in Europe. From English schools came the great masters whose writings instructed generations, centuries even, of Insular and continental students alike: one has only to think of the works of Aldhelm, Bede and Alcuin, which were copied and studied intensively up to the twelfth century and beyond. This achievement is all the more remarkable when one considers that the Anglo-Saxons were among the first peoples in Europe who were obliged to learn Latin as a foreign language if Christianity - a religion of the book par excellence - was to flourish. Throughout the Anglo-Saxon period, English schools benefited from the instructi…

Neutrino and dark radiation properties in light of recent CMB observations

2013

Recent cosmic microwave background measurements at high multipoles from the South Pole Telescope and from the Atacama Cosmology Telescope seem to disagree in their conclusions for the neutrino and dark radiation properties. In this paper we set new bounds on the dark radiation and neutrino properties in different cosmological scenarios combining the ACT and SPT data with the nine-year data release of the Wilkinson Microwave Anisotropy Probe (WMAP-9), baryon acoustic oscillation data, Hubble Telescope measurements of the Hubble constant, and supernovae Ia luminosity distance data. In the standard three massive neutrino case, the two high multipole probes give similar results if baryon acoust…

Measurement of the Inclusive NuMu Charged Current Cross Section on Carbon in the Near Detector of the T2K Experiment

2013

T2K has performed the first measurement of nu(mu) inclusive charged current interactions on carbon at neutrino energies of similar to 1 GeV where the measurement is reported as a flux-averaged double differential cross section in muon momentum and angle. The flux is predicted by the beam Monte Carlo and external data, including the results from the NA61/SHINE experiment. The data used for this measurement were taken in 2010 and 2011, with a total of 10.8 x 10(19) protons-on-target. The analysis is performed on 4485 inclusive charged current interaction candidates selected in the most upstream fine-grained scintillator detector of the near detector. The flux-averaged total cross section is (…
