New chemical topologies based on calixarene threading
(Universita degli studi di Salerno, 2014-03-11)Recently, Neri et al. have introduced an efficient method to obtain endo-cavity complexation and through-the-annulus threading of large calixarenes by exploiting the inducing effect of the weakly coordinating tetrakis[3, ... -
Le potenzialità dell’e-learning nell’apprendimento della matematica
(Universita degli studi di Salerno, 2011-02-18)La tesi indaga e discute le potenzialità dell’e-learning nell’apprendimento della matematica. Oggi la tecnologia dell’informazione e della comunicazione non è più strettamente legata a qualche quadro teorico. In passato ... -
Imbedding and compactness results in some function spaces
(Universita degli studi di Salerno, 2011-03-16)Abstract Nello studio di vari problemi ellittici con soluzioni in spazi di Sobolev S( ) (con o senza peso) definiti su un aperto di Rn, non necessariamente limitato o regolare, spesso risulta necessario stabilire ... -
Functionalized Syndiotactic Polystyrene
(Universita degli studi di Salerno, 2012-02-14)La sintesi di materiali polimerici da metodo di modificazione, per ottenere le proprietà desiderate in polimeri, è un argomento importante in chimica dei polimeri e tecnologia. Molto spesso, proprietà desiderate non sono ... -
Nb nanoporous ultrathin films: matching effects and interconnected wires
(Universita degli studi di Salerno, 2012-03-03)When the applied magnetic field is higher than the lower critical field but below the upper critical field, a type-II superconductor allows magnetic flux to penetrate it in the form of vortices, a tiny normal area ... -

Dissipation, mixing and two level system in quantum field theory
(Universita degli studi di Salerno, 2012-04-30)In this dissertation we discuss several aspects of a two level system (qubit) in the context of quantum mechanics and quantum field theory. The presence of geometrical phases in the evolution of a qubit state is shown. We ... -
Polymorphism and co-crystalline phases of polymers
(Universita degli studi di Salerno, 2012-02-04)Crystalline phases are extremely relevant for properties and applications of many polymeric materials. In fact, their amount, structure and morphology constitute the main factors controlling physical properties of fibers, ... -
Logit dynamics for strategic games mixing time and metastability
(Universita degli studi di Salerno, 2012-04-18)A complex system is generally de_ned as a system emerging from the interaction of several and di_erent components, each one with their properties and their goals, usually subject to external inuences. Nowadays, complex ... -
Electric transport properties of S/F hybrids: weak and inhomogenous ferromagnet
(Universita degli studi di Salerno, 2012-03-30)Superconductivity (S) and ferromagnetism (F) are competing phases whose coexistence is unlikely to occur. Exceptions require a non−uniform profile both for the pairing and the magnetization, as in the case of the FFLO ... -
