Influence of temperature on the actuation voltage of RF-MEMS switches
No full textMost of the actual applications for RF-MEMS switch require high reliability, but consolidated qualification procedures are still lacking. This paper focuses, in particular, on the role of temperature on the switch reliability from a mechanical point of view, showing how this depends on the switch architecture and membrane material. Double clamped switches are sensitive to buckling, and this is the factor limiting their operational temperature, even though the range exploitable can be wide enough for many applications. Residual stress and thermal expansion coefficient of the mobile membrane are the most important parameters to understand and control this phenomenon. Cantilever switches are less influenced by the temperature in their performances, and have a much wider operational range. Other temperature-related factors are affecting the switch reliability in this case, such as elastic modulus variation, dielectric charging effects and creep
A Coin-Sized Detector for Room-Temperature X-Ray Photons and Electron Spectroscopy
No full textThe system design and characterization of a compact single-SDD (Silicon Drift Detector) module for X-ray and electron spectroscopy in a windowless, room-temperature, vacuum environment is presented. The measured SDD leakage current density at +22° C is only 31 pA/cm2. The module, characterized at room temperature with 55Fe X-rays, demonstrated state-of-the-art performance: an energy resolution of 136 eV FWHM at 5.9 keV has been obtained with 1 μs filter peaking time, and its count-rate capability has been tested up to 4.2 Mcps with a 32 ns filter peaking time while maintaining an energy resolution of less than 200 eV FWHM at 5.9 keV

Didattica e ricerca. L’esperienza del Laboratorio aragonese e sforzesco
No full textIn the workshop on Diplomatic correspondences in the Italian Renaissance, directed in January-May 2018 by Francesco Storti and Francesco Senatore in the Istituto italiano per gli studi filosofici of Naples, 12 undergraduate and graduate students learned to read and trascribe italian diplomatic dispatches of the 15th cent., producing a specimen of scientific edition. In the opinion of the author, such activities and similar ones are very useful for future school teachers and scholars and they could be introduced in the university and pHD courses of history. Students of humanistic sciences should have concrete contacts with the historical research on primary sources. On the other hand, editing of historical sources could become a marginal activity because it is not enough appreciated in the current research evaluation processes.

Fotografie di Sergio Oriani
Il curatore della mostra, Stefano Zuffi, ha voluto inquadrare criticamente l’opera di Raffaello
proveniente dal Museo di Budapest, ponendola tra la Vergine delle Rocce di Francesco Melzi,
proveniente dall’Istituto delle Suore Orsoline di Milano e la Madonna della Rosa di Giovanni
Antonio Boltraffio, proveniente dal Museo Poldi Pezzoli della stessa città. L’architetto Corrado
Anselmi ha progettato un affascinante allestimento, concependolo come un percorso che si
sviluppa attraverso tre soste utili all’ammirazione delle opere. L’autore Francesco Murano,
spiega con ricchezza di particolari i vincoli del progetto illuminotecnico e le scelte luministiche.Once again, for the Christmas season, the Municipally of Milan decided to display an important work in the frame of the Palazzo Marino’s Alessi Hall. For this year 2014, the choice has been to propose the Estheràzy Madonna by Raphael, from the Museum of Budapest.
The exhibition curator, Stefano Zuffi, wanted to critically frame to work of Raphael by placing it between the Vegine delle Rocce (Virgin of the Rocks) by Francesco Melzi, coming from the Milan’s Istituto delle Suore Orsoline, and the Madonna della Rosa by Giovanni Boltraffio, from the Milanese Museo Poldi Pezzoli.
The Architect Corrado Anselmi designed a fascinating display, convinced as a path that develops through three stops that are useful for the enjoyment of the works.
