Quantum batteries: The future of energy storage?
No full textJames Quach is a Science Leader at the CSIRO (Commonwealth Scientific and Industrial Research Organisation), where he leads the Quantum Batteries team. He is the inaugural Chair of the International Conference on Quantum Energy. Previously he was a Ramsay Fellow at The University of Adelaide, a Marie Curie Fellow at the Institute of Photonics Science in Barcelona, and a JSPS Fellow at the University of Tokyo. He completed his PhD at the University of Melbourne in Physics. His research interest is in all things quantum, working in quantum technology, quantum computing, quantum biology, quantum chaos, quantum thermodynamics, and quantum gravity. Giulio Cerullo is a Full Professor with the Physics Department, Politecnico di Milano, where he leads the Ultrafast Optical Spectroscopy laboratory. Prof. Cerullo's research activity deals with the generation of tunable few-optical-cycle light pulses and their application to the study of ultrafast processes in (bio)-molecules and quantum confined solids. He has been General Chair of CLEO/Europe and Ultrafast Phenomena conferences. He is a Fellow of the Optical Society and of the European Physical Society and a member of Accademia dei Lincei. In 2023 he received the Quantum Electronics Prize from the European Physical Society. Tersilla Virgili is a senior researcher at the Institute of Photonics and Nanotechnologies of the National Research Council (CNR) in Milano, Italy. She graduated in Physics at the University of Bologna and got her PhD at the University of Sheffield (UK). Her scientific activity is represented by more than 90 different international publications and book contributions. Her scientific interest is mainly based on the following areas: 1) spectroscopy of organic, hybrid, and inorganic material for photonic and photovoltaic devices; 2) photophysics of organic microcavities working in weak and strong coupling regimes; and 3) organic quantum batteries

Wideband equivalent-circuit model analysis, realization and time-domain spectroscopy characterization of terahertz periodic metamaterial devices
No full textIn my PhD thesis, I have thoroughly researched THz periodic metamaterial devices by dealing with all the phases of their development: electromagnetic analysis, design, fabrication, characterization, and data post-processing. Initially, for the analysis and design phases, I have adopted an analytical/numerical perspective for the retrieval of the devised circuit topologies. In particular, I have developed and applied equivalent circuit models and parametric macromodels for the physical investigation and optimization of the devices; these methods have been validated by proving their efficiency and effectiveness through the comparison with finite-element method based simulations. Also, they guarantee a wider range of applications in terms of frequency spectra, complexity of geometrical shapes, and material characteristics. For the realization phase, I have used a heuristic procedure of micro-fabrication and after evaluating possible non-idealities, I have made tolerance studies in order to obtain a stable electromagnetic performance. For the characterization of the flexible devices, I have used custom THz-TDS setups for both reflection and transmission-modes; the resulting configurations have proved to be compact and interesting also for further integration in embedded measurement systems. For the data analysis phase, I have post-processed the acquired measurements by implementing retrieval procedures of the constitutive parameters of the samples. Other than topics specifically related to the THz field, I have developed some models of analytical/numerical character for the study of scatterers with discontinuous impedance boundary conditions
Cancer-Related Anemia and Frailty in Older Persons
No full textAnemia, defined by the World Health Organization as a hemoglobin concentration lower than 13 g/dL in men and 12 g/dL in women, is particularly prevalent at advanced age. Nevertheless, it is not a condition simply explained by the normal aging process. Anemia represents a potentially reversible condition associated with numerous adverse health-related events, including hospitalization, disability, and mortality in older persons. Low haemoglobin concentrations are particularly common among patients with cancer due to direct (e.g., micro- and macroscopic blood losses) and indirect causes (e.g., increased production of pro-inflammatory cytokines with consequent reduction of erythropoietin release and erythropoiesis). The impaired oxygen-carrying capacity caused by the presence of anemia may play a major role in multiple clinical manifestations of cancer, such as dyspnea, fatigue, exhaustion, dizziness and/or headache. In the present review, we discuss the importance of low hemoglobin concentrations and anemia as important determinants of the frailty syndrome, a condition commonly present among cancer patients. Treatment of cancer-related anemia may improve quality of life and health-related outcomes (including disability and mortality) in older patients with oncological conditions
Carmen Laforet y la generación del 50. La narrativa breve y La mujer nueva (1950-1955)
No full textThe aim of the following investigation is the analysis of the evolution of Carmen Laforet’s poetics from the 1950s onwards. The Catholic conversion of the author entails a literary approach to themes that must be considered fundamental for the generación del medio siglo and that, although indirectly, determine the process of adherence of the author to the abovementioned group. Therefore, some short stories and novels written after 1950 and the novel La mujer nueva (1955) are analysed, with particular attention to the process of configuration of the main characters in the works under investigation
“Dondequiera que vayan mis ojos” Un sepulcro en el cielo, l'ultimo romanzo di Vintilă Horia
No full textVintilă Horia es, sin duda, una víctima más del clima de hostilidad que el mundo ha conocido tras las acontecimientos bélicos de la Segunda Guerra mundial. Su trayectoria literaria, tanto novelística como ensayística, aborda el tema, nada fácil, del exilio como herramienta para la salvación humana. El exilio horiano, que el autor rumano vive en la España franquista, se refleja en su producción narrativa deforma evidente. Su última novela, Un sepulcro en el cielo (1987), diario apócrifo de El Greco, es la representación fiel de los valores hispánicos. Gracias a éstos el autor rumano reconoce e interpreta su proprio exilio como recurso para alcanzar un nivel de trascendencia que todo exiliado necesita. A través de una peculiar representación del espacio de exilio, Vintilă Horia se adueña de la figura de El Greco, otro exiliado que como él mismo, viaja hacia Occidente y termina encontrando cobijo en España. Esto otorga al país ibérico el papel de único refugio posible, tierra de valores cristianos que no se someten a la hostilidad de la historia. Asimismo, gracias a un proceso de “fusión mítica” el autor expresa su idea de la novela como técnica del conocimiento, y reutiliza la figura del pintor cretense para entender, metabolizar y, finalmente aceptar su destino de exiliado

Ultrafast lasers: From femtoseconds to attoseconds
No full textWe review the capability of lasers to generate light pulses of incredibly short duration, from a few femtoseconds (1 fs = 10 -15 s) in the visible down to a few tens of attoseconds (1 as = 10 -18 s) in the extreme-ultraviolet, reaching peak powers up to several petawatts (1 PW = 10 15 W)
