Water Dynamics in Biological Systems investigated using Neutron Scattering Techniques
Living systems can not survive in absence of the water environments which play a fundamental role in living functions. Thus in the scienti?c community many studies were and are addressed to characterize water and its dynamics properties in biological systems. However, a clear description of water in such systems has been not reached yet. In fact, the investigations performed with di?erent techniques - those based on Nuclear Magnetic Resonance or those based on Neutron Scattering - look at di?erent di?usive motions and interactions water-biomolecules, leading controversial results and hence generating many debates between scientists. In this thesis we support the idea that two water populati…
Minoranze migranti
2013
Si affronta la doppia valenza dei nuclei di migranti extracomunitari: popoli in movimento da una parte e minoranze etniche dall'altra. Con conseguenze proprie della doppia valenza: esigenza di integrarsi e bisogno di coltivare la propria identità. The double value of migrant peoples: peoples in migration, by one hand, and ethnic minorities, by the other. With specific consequencies of the double value: to integrate to the majorities and to reaffirm originary identity.

High Bias Voltage CZT Detectors for High-flux Measurements
2017
In this work, we present the performance of new travelling heater method (THM) grown CZT detectors, recently developed at IMEM-CNR Parma, Italy. Thick planar detectors (3 mm thick) with gold electroless contacts on CZT crystals grown by Redlen Technologies (Victoria BC, Canada) were realized, with a planar cathode covering the detector surface (4.1 x 4.1 mm(2)) and a central anode (2 x 2 mm(2)) surrounded by a guard ring electrode. The detectors, characterized by low leakage currents at room temperature (4.7 nA/cm(2) at 1000 V/cm), allow good room temperature operation even at high bias voltages (> 7000 V/cm). At low rates, the detectors exhibit an energy resolution around 4 % FWIEM at 59.5…
Microscale X-ray mapping of CZT arrays: Spatial dependence of amplitude, shape and multiplicity of detector pulses
2018
In this work, we present the results of a microscale X-ray mapping of a 2 mm thick CZT pixel detector, with pixel pitches of 500 μm and 250 μm, using collimated synchrotron X-ray sources at the Diamond Light source (U. K.). The detector is dc coupled to a fast and low noise ASIC (PIXIE ASIC), characterized only by the preamplifier stage. A custom 16-channel digital readout electronics was used, able to perform online fast pulse shape and height analysis (PSHA), with low dead time and reasonable energy resolution at both low and high fluxes. The detector allows high bias voltage operation (> 5000 V/cm) and good energy resolution at room temperature (5.3 %, 2.3 % and 2.1 % FWHM at 22.1, 59…
Il contrasto all’odio e alla disinformazione in rete. Prime evidenze dalle campagne del progetto COMMIT
2023
Negli ultimi anni l’Europa ha dovuto affrontare le conseguenze di una crescente propaganda estremista, radicale e terroristica, che sempre più spesso trova spazio nei social media. Il contributo descrive il progetto COMMIT (COMMunIcation campaign against exTremism and radicalisation) che ha sviluppato, tra il 2020 e il 2022, una serie di attività di ricerca e di intervento con l’obiettivo, da un lato, di mappare il fenomeno della radicalizzazione online nei quattro Paesi partner (Italia, Grecia, Austria e Paesi Bassi) e individuare le caratteristiche dei gruppi più vulnerabili, dall’altro, di sviluppare le competenze di media literacy e di advocacy dei giovani destinatari del progetto.
Raman analysis of insulin denaturation induced by high-pressure and thermal treatments
2012
Raman spectroscopy has been used to investigate different conformational states of bovine pancreatic insulin: the native form and several structurally modified states with different extent of denaturation induced by thermo-chemical treatment and by applying very high pressure (up to 8 GPa) using a diamond anvil cell. High-pressure results confirm the peculiar strength to volume compression of insulin and largely extend the pressure range of its structural stability (0-4.2 GPa). Above 4.2 GPa, insulin undergoes an irreversible structural transition that, once pressure is released, leaves the sample in a new conformational state. The protein secondary structure after the pressure treatment re…
