Abstract (sommario):

Silicon-based discrete high-power devices need to be designed with optimal performance up to several thousand volts and amperes to reach power ratings ranging from few kWs to beyond the 1 GW mark. To this purpose, a key element is the improvement of the junction termination (JT) since it allows to drastically reduce surface electric field peaks which may lead to an earlier device failure. This thesis will be mostly focused on the negative bevel termination which from several years constitutes a standard processing step in bipolar production lines.

Abstract (sommario):

This work deals with the coupling between high temperature steam electrolysis and carbon dioxide methanation (hydrogenation) to produce a synthetic gas directly injectable in the natural gas distribution grid. This system concept is one of the existing possibilities related to a pathway named Power-to-gas. According to this strategy, low-priced surplus electric energy coming from renewable energy sources (RES) or nuclear plants can be converted into chemical energy of a fuel in order to store it for a longer time. Another purpose is to compensate the unbalances of the electric grid due to the

Abstract (sommario):

The work of this Ph.D. thesis has been realised in the field of a promising and largely studied technological material: the carbon nanotubes (CNTs). Since 1991 a large number of attempts have been conducted, trying to exploit the outstanding potential of this carbonaceous material, in order to improve the properties of several matrices. The most important application is the production of polymer matrices composites (PMCs), but in last decades an increasing number of metal matrix ones (MMCs) have been presented and recently also ceramic matrix (CMCs) applications have been attempted. Despite ma

Abstract (sommario):

Questa tesi riguarda le proprietà dielettriche e di assorbimento alle microonde della resina epossidica caricata di nanocariche. Tre differenti nanocariche a base di carbonio sono state usate in questa tesi: Carbon black (CB) nanofibre di carbonio (CNF) e nanotubi di carbonio (CNT). Inoltre,sono stati provati vari processi di dispersione delle nanocariche nella resina, per analizzare gli effetti della distribuzione delle nanocariche sulle proprietà dielettriche dei composti che ne risultavano. È stata misurata la permettività usando un sistema VNA nella banda-X (8,2-12,4 GHz) usando il metodo

Abstract (sommario):

La presenza nel biochar di carbonio labile (e.g. carbonio organico disciolto (DOC)) e di sostanze inorganiche (e.g. metalli pesanti) potenzialmente dannosi può limitare o impedire l’utilizzo del biochar per interventi di risanamento ambientale. Sono stati prodotti biochar da pirolisi lenta a diverse temperature (i.e. 300, 450 e 700 °C) da diversi tipi di feedstock (i.e. cippato da residui di lavorazione del legno (WC), lignina (LG), digestato da fanghi di depurazione (DSS), corteccia di pino (PB)). Il contenuto totale, la lisciviazione e la biodisponibilità di metalli, quali Cd, Cr, Cu, Ni, Pb

Abstract (sommario):

Throughout the last century, theoretical and experimental research made by the international nuclear physicists community has led to important advancement in the knowledge of the mechanisms that govern the behavior and stability of the nuclei. The technological improvements necessary to support this research has often opened the way to new applications in other field of science and industry which directly reflects in our common life experience. Nowadays, Europe is becoming more and more a leader in both theoretical and experimental nuclear physics, as testified by the presence on its territo

Abstract (sommario):

Graphene is a monolayer of carbon atoms with remarkable electronic and mechanical properties. The attractive electronic properties of thin and thick films made of carbon nanotubes (CNTs) and graphene are increasingly being exploited for environmental and biological sensors. In particular, their sensitivity, selectivity, fast response time, ability to operate at room temperature, and their passive nature (no power consumption) provide competitive advantages of CNTs in sensor applications. However, their design as RF wireless sensors requires the integration of an antenna with the sensor elemen
