Environmental influence on the IR fluorescence of Xe-2* molecules in electron beam excited Ar-Xe mixture at high density
No full textWe report new measurements of the near infrared (NIR) Xe2* excimer fluorescence in an electron beam excited Ar (90%) Xe (10 %) mixture at room temperature. Previous measurements up to a density N≈ 2× 1026 m-3 discovered a broad excimer fluorescence band at ≈ 7800 cm-1, whose center is red shifted by increasing N [A.F. Borghesani, G. Bressi, G. Carugno, E. Conti, D. Iannuzzi, J. Chem. Phys. 115, 6042 (2001)]. The shift has been explained by assuming that the energy of the optical active electron in the molecule is shifted by the density dependent Fermi shift and by accounting for the solvation effect due to the environment. We have extended the density range up to N≈ 6× 1026 m-3, confirming the previous measurements and extending the validity of the interpretative model. A detailed analysis of the width of the fluorescence band gives a value of 2.85 nm for the size of the investigated excimer state. Such a large value lends credibility to the validity of the proposed explanation of the experimental findings

Werner Sombart and the global society. Anticipations from a classic author of sociology
No full textThe article examines the most salient works in which the sociologist Werner Sombart saw the dimension of globality as a social element, constitutive of mo- dernity and its future. The aim is to understand the role of globality, as an idea and a phenomenon, in the constitution in all aspects of society (economic, political, cultural, anthropological). The Works to which the article refers show a global society, one that goes from the time of Sombart to the present day, as the author had already envisioned in all their potentialities and criticalities
Ultrafast charging station for electrical vehicles: Dynamic modelling, design and control strategy
No full textThe paper deals with mathematical modelling and the control system for UltraFast Charging Stations (UFCS) based on DC micro-grid concept and Energy Storage System Integration to feed new Electrical Vehicles (EVs) at 800V DC in order to reach the EVs power requirement for charge-time less than 10 min. The UFCS integrates a battery energy storage system (BESS) to reduce the peak power of AC main grid, decoupling the dynamics of the DC charging station from the AC grid by means of its dedicated control system. Designing procedure and Control Strategy, based on Load Levelling power management, are dealt with numerical simulation results in Matlab-Simulink software, presented in order to verify UFCS performance and the charging station's dynamics
