An ecological approach to the integrated monitoring of freshwater ecosystems
(Universita degli studi di Salerno, 2019-02-06)The concept of integrated environmental monitoring includes the gathering of all the information necessary to obtain a comprehensive view of ecosystem status, processes and functionality, through a classical ecological ... -
Lo pseudotensore energia-impulso in teorie estese della gravitazione
(Universita degli studi di Salerno, 2018-07-12)The gravitational field’s energy and momentum definitions are treated in extensive gravitation theories, through the generalization of the energymomentum pseudotensor, defined by Einstein in general relativity. This ... -
Electrical and thermal transport properties of superconducting materials relevant for applications
(Universita degli studi di Salerno, 2018-07-06)Superconducting materials are used in several applications among which the large-scale ones take advantage of the high energy transport capabilities of superconductors due to the low losses in electrical conduction. From ... -
Calixarene based catalytic systems
(Universita degli studi di Salerno, 2018-02-22)Catalysis is the essence of chemistry as it provides useful tools to make and brake chemical bonds. As nature has been a guide to many scientists, it’s no surprise that in the field of catalysis enzymes were a source of ... -
Metathesis reactions catalyzed by ruthenium complexes for the self-healing of aeronautical materials
(Universita degli studi di Salerno, 2018-03-05)In this PhD thesis work, Ruthenium catalysts were covalently and non-covalently linked to carbon-based nanomaterials, in order to give self-repairing ability to the aeronautical materials. These supported catalysts have ... -
On Vector-Valued Schrodinger Operators in Lp-spaces
(Universita degli studi di Salerno, 2018-04-06)We construct a realization Ap of A in the spaces Lp(Rd;Cm), 1 p < 1, that generates a contractive strongly continuous semigroup. First, by using form methods, we obtain generation of holomorphic semigroups when the ... -
Phisical chemistry of plasmas and applications to cultural heritage and material science
(Universita degli studi di Salerno, 2018-03-04)In this project, the attention has been focused on the laser ablation process and on laser induced plasmas spectroscopic study for two different technological applications. First of all, the analytical LIBS (Lase Induced ... -
Development of iron-based catalysts for the coupling of carbon dioxide with epoxides
(Universita degli studi di Salerno, 2018-03-07)Beside the environmental and energetic issues, carbon dioxide can be considered as a resource. Many chemical transformations based on CO2 as C-1 building block have been developed. The coupling reaction of epoxides with ... -
Event triggering and deep learning for particle identification in KM3NeT
(Universita degli studi di Salerno, 2018-04-11)Neutrino astronomy experiments like KM3NeT allow to survey the Universe leveraging the properties of neutrinos of being electrically neutral and weakly interacting particles, making them a suitable messenger. Observing ... -
