Tailoring the structural and surface properties of TiO2 thin films and TiO2-based nanolayers, with heat treatments, layer thickness, and oxide mixtures
(Universita degli studi di Salerno, 2021-12-15)Titanium dioxide (TiO2), also known as titanium (IV) oxide or titania, is naturally available on the Earth as a bright, fine, and white pigment. Thanks to its unique properties, such as high refractive index, chemical ... -
Hidden Structures and Conflicting Items in Combinatorial Optimization Problems
(Universita degli studi di Salerno, 2023-02-14)Combinatorial optimization-based methods are widely used to solve complex real life problems. In this thesis, we use some of these methods for addressing several emerging combinatorial opti- mization problems on graphs ... -
Advanced Modeling of Microlensing Events
(Universita degli studi di Salerno, 2023-04-17)The search for exoplanets is one of the most exciting challenges. From the first exoplanets discovered around the pulsar PSR B1 257+12 back in 1992 until today there are over 5200 exoplanets discovered. And the number ... -
Orbital motion, periastron advance and galaxy rotation curves beyond General Relativity
(Universita degli studi di Salerno, 2023-01-02)The Extended Theories of Gravity (ETG) have become one of the most investigated the- oretical proposals among the alternative explanations for the observed flatness of galaxy rotation curves, related to the dark matter ... -
Gravitational lensing by massive and Exotic objects
(Universita degli studi di Salerno, 2023-02-21)Space-time is curved by the presence of massive bodies and this curvature influences the motion of the bodies themselves: this leads to a geometry in constant evolution. One of the consequences is that even light, supposed ... -
Transition Metal Dichalcogenides and Carbon Nanomaterials in Field Effect Devices and Photodetectors
(Universita degli studi di Salerno, 2023-02-20)This PhD thesis focuses on the electronic and optoelectronic characterization of devices based on low-dimensional materials and on a first approach to fabrication of 2D transition metal dichalcogenide (TMD) field effect ... -

Praseodymium and manganese doped Ca2RuO4: crystals growth and physical properties
(Universita degli studi di Salerno, 2023-07-17)Layered ruthenates have received a great attention in condensed matter physics due to the richness of their physical properties and the related phase diagram. Ruthenate compounds show a strong interplay between electronic, ... -
Numerical Modeling of Stochastic Differential Problems with Applications
(Universita degli studi di Salerno, 2023-01-27)The interest in the study of stochastic differential equations has grown considerably in recent years. The main reason for this interest is that stochastic differential equations are a potential tool for modeling ... -
Λ + c production vs the event charged-particle multiplicity in pp collisions at 13 TeV with ALICE at the LHC
(Universita degli studi di Salerno, 2023-03-22)The Quantum Chromo-Dynamics (QCD) theory predicts, in condition of very high temperature and/or energy density, a phase transition from the ordinary nuclear matter to a colour-deconfined medium called Quark–Gluon Plasma ... -
Detailed study of the 2010-2014 Pollino (Italy) seismic sequence with absorption and scattering imaging of the surrounding area
(Universita degli studi di Salerno, 2020-02-04)A detailed study of the seismic sequence occurred in the western sector of the Pollino Range (Southern Italy) between 2010 and 2014, and an imaging of the surrounding area, have been performed in this thesis. The sequence, ... -
Polyhedral analysis and branch and cut algorithms for some NP-hard spanning subgraph problems
(Universita degli studi di Salerno, 2020-01-07)There is a widespread need to use a quantitative approach for the solution of decision problems that arise in many different areas of real life. The goal is to choose which decisions to take to manage a real system as ... -
A game theoretical approach to safe decision making system development for autonomous machines
(Universita degli studi di Salerno, 2021-03-20)One of the major technological and scientific challenges in developing autonomous machines and robots is to ensure their ethical and safe behavior towards human beings. When dealing with autonomous machines the human ... -
Methodologies for environmental risks assessment related to the exploitation of energy geo-resources
(Universita degli studi di Salerno, 2021-10-05)The increasing exploitation of geo-energy resources to satisfy the needs of the world's population has also led to a focus on the risks associated with this type of human activity. It is in this context that this thesis ... -
Exploring the transport properties of quantum systems on different lenght scales
(Universita degli studi di Salerno, 2021-11-10)In this thesis, after introducing some theoretical aspects of Mott insulators, pure single crystals of the Mott insulator Ca2RuO4 was investigated from an experimental point of view. The surprisingly low current density ... -
Noncoercive nonlinear elliptic equations in unbounded domains
(Universita degli studi di Salerno, 2020-01-02)This research thesis is mainly devoted to the study of noncoercive Dirich let problems with discontinuous coefficients in unbounded domains. The presence of the noncoercive operator does not allow us to use classical the ... -
Applied superconductivity to accelerator magnets
(Universita degli studi di Salerno, 2020-09-24)The transport properties of superconducting tapes and wires for the electrotechnical applications have been investigated. The characterization measurements were carried out in our laboratory with particular ... -
Local and global properties of Jacobi related geometries
(Universita degli studi di Salerno, 2019-12-18)In this thesis local and global properties of Jacobi and related geometries are discussed, which means for us that so-called Dirac-Jacobi bundles are considered. The whole work is roughly divided in three parts, which ... -
