Metodi innovativi per la realizzazione di migliori photodetector a base di nanotubi di carbonio e silicio.

Different approaches to make carbon nanotube-silicon heterojunctions have been studied. Starting from prefabricated silicon substrates, composed of an n-type silicon wafer with a silicon nitride top layer and a metallic back, the heterojunctions have been made by different approaches. Initially by direct growth of the nanotubes over the nitride layer by means of chemical vapor deposition (CVD) and then by the deposition of carbon nanotube films using a transfer printing method. The morphology...

Screening di materiali tramite ICP-MS per caratterizzazione di background in esperimenti di bassa radioattività

Search for very rare astroparticle physics events, such as Neutrinoless Double Beta Decay or direct Dark Matter interactions demands for extremely low background environments and materials for the experiment construction. The former requirement is fulfilled by underground laboratories, such as the Laboratori Nazionali del Gran Sasso of INFN, where the overburden rock reduces the cosmic ray flux by six orders of magnitude with respect to the sea level. The latter requirement, i.e., the materia...

Analisi e stima della composizione in massa dei raggi cosmici ad altissima energia e le sue implicazioni astrofisiche usando i dati misurati dall'Osservatorio Pierre Auger

The most reliable technique to measure the mass composition of Ultra-High-Energy Cosmic Rays (UHECRs) is the simultaneous measurement of the depth, Xmax , at which the number of particles in an air shower reaches its maximum and the energy, E, of the shower. The most efficient way to detect these quantities is the fluorescence technique currently employed by the Pierre Auger Observatory and the Telescope Array. The data measured by the Pierre Auger Observatory of the first two moments (mean a...

PSYCHOSOMATIC INSIGHTS IN HEALTH MANAGEMENT OF CHRONIC NON-COMMUNICABLE DISEASES

The thesis is based on studies performed at Department of Medicine and Public Health during XXXIV doctoral course, curriculum “Epidemiology, preventive, rehabilitative and occupational medicine’ (Coordinator Prof. Claudio Ferri) from 2018-2021, under supervision Prof. Domenico Passafiume and, Prof. Dina Di Giacomo. Doctoral Programme expected learning of the experimental techniques and methodologies of scientific research, through access to different types of patients by age, clinical patholo...

Telehealth care and remote monitoring strategies in heart failure patients: A systematic literature review

ABSTRACT Background. Heart Failure (HF) is a cardiac clinical syndrome which derive both from cardiac and extra-cardiac conditions. Heart failure is an increasing public health issue and affects a great number of people worldwide. The prevalence of heart failure is generally estimated at 1% to 2% of the general adult population, up to 10% in people aged over 70. Heart failure impacts on patients' living and working abilities, representing a high mortality-related disease. Despite the huge amo...
