Exploring plasmons in silicon nanowires with different sizes and morphologies

Silicon nanowires (SiNWs) are extensively studied in the scientific community due to their remarkable electrical and optical properties. Recent studies have demonstrated the appearance of Plasmonic Resonance (PR) in SiNWs. It has been recently demonstrated in literature that SiNWs with a cylindrical shape sustain longitudinal plasmonic resonance (LPR) and transversal plasmonic resonances (TPR). In this thesis work, I present the results on SiNWs with tapered morphology. These SiNWs present a ...

Superconducting Thin Films for Magnetic Confinement Fusion: Growth, Electrical and TEM Microstructural Characterization, with Insights into Ion Irradiation

The development of efficient magnetic confinement systems for nuclear fusion reactors requires superconducting materials capable of operating under high magnetic fields, intense irradiation, and demanding thermal conditions. High-temperature superconductors (HTS) are promising candidates for these applications due to their high critical current densities and enhanced magnetic-field tolerance compared to conventional superconductors. This thesis focuses on the growth and comprehensive struc...

Contaminanti Organici nei Prodotti per la Cura Personale: bioaccumulo ed effetti in vivo e in vitro su organismi acquatici e sull’uomo

Questo progetto di dottorato, nell'ambito del Programma Operativo Nazionale Ricerca e Innovazione 2014-2020 (CCI 2014IT16M2OP005), risorse FSE REACT-EU, Azione IV.4 “Dottorati e contratti di ricerca su tematiche dell’innovazione”, mira a valutare gli effetti dei contaminanti organici presenti nei prodotti per la cura della persona su modelli sperimentali acquatici invertebrati, come il Mytilus galloprovincialis, e su altre specie acquatiche, come il Sander lucioperca. I contaminanti organici ...

The Many Lives of Dark Matter: WIMPs, FIMPs, and EFTs

From Weakly Interacting Massive Particle (WIMPs) to Feebly Interacting Massive Particles (FIMPs), the landscape of Dark Matter models has expanded as experimental constraints have evolved. This thesis follows that evolution. We begin with the standard WIMP paradigm, where increasingly precise experiments have imposed stringent bounds on the simplest realizations. A number of well-motivated extensions, such as models with additional scalar or gauge bosons, are reviewed to illustrate how Dar...

Beni comuni e beni collettivi: le appartenenze intergenerazionali

L’influenza esercitata sulle categorie tradizionali del diritto privato dai continui mutamenti degli assetti economico-sociali e dalla costante emersione di nuove tipologie di interessi costituisce un dato ormai noto ed ampiamente acquisito all’immaginario collettivo della scienza civilistica contemporanea. Al giorno d’oggi, infatti, qualunque itinerario di ricerca deve essere affrontato tenendo a mente che le sfide sollevate dall’affermazione e dalla sempre maggiore diffusione delle nuove te...

Bioconversione di oli alimentari esausti in poliidrossialcanoati (PHA): sviluppo ed ottimizzazione di processi e di applicazioni relative ai polimeri prodotti su scala di laboratorio ed industriale.

QUALITÀ E SICUREZZA DI MATRICI ALIMENTARI CON PROPRIETÀ SALUTISTICHE

Food safety and quality are two fundamental pillars for protecting consumer health. Furthermore, the consumption of functional foods brings specific health benefits, improving well-being or reducing the risk of disease. These foods are promoted through nutritional and health claims, communication tools regulated by European Union. However, their use requires rigorous scientific and regulatory control to avoid misleading practices. This thesis provides an overview of the chemical quality and ...

Genetic Variability and Drug Resistance of Hepatitis B Virus in Treatment-Naïve Chronic Hepatitis B Patients

Despite the availability of an effective vaccine and antiviral therapies designed to suppress viral replication by targeting the catalytic region of the RT gene, HBV infection remains a significant public health challenge worldwide. This study aimed to examine the variability of the HBV whole genome in HBsAg-positive individuals who had never received specific antiviral treatments with NAs. The goal was to investigate the prevalence of viral quasispecies among these patients, focusing on thos...

MODULATION OF THE WNT/BETA-CATENIN PATHWAY IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION (BETA-MI STUDY)

Background: Cardiac fibrosis is central to post-infarction remodeling and heart failure development. The Wnt/β-catenin pathway is involved in fibrosis and myocardial repair, but its clinical significance remains unclear. This study aims to investigates β-catenin and its inhibitor DKK1 after a myocardial infarction and explores their modulation by P2Y12 inhibitors. Methods: A single-center observational cohort study included 50 patients undergoing PCI: 40 with STEMI and 10 with CCS. β-catenin...
