Polarization holographic recording in polymeric and liquid crystalline materials
(2006)Optical studies related to polarization holographic recording in photosensitive materials, as azo compounds, liquid crystals and polymeric mixtures, and dye doped polymers, were carried out. The interest in this type of ... -
Properties of biomolecules at the interfaces: studies and characterization of chromonic mesogens, from the basis to applications
(2013-11-28)The study of the interaction between molecules, in particular biological molecules and liquid crystals (LC), has experienced a huge growth in the recent years because of the development in devices engineering applied not ... -
Properties of entanglement in a Spin Chain with impurities
(2012-11-09)In this thesis we have studied the e®ects on ground-state entanglement and quantum-state transfer caused by the presence of one and two diagonal impu- rities in a 1D ring-shaped spin-1 2 hamiltonian with XX ferromagnetic ... -
Proprietà elettroniche e vibrazionali di strati sottili adsorbiti su substrati metallici
(2008)Understanding the adsorption, catalytic, and electronic properties of metal/metal interfaces is one of the foremost aims of surface science. In fact, through the tailoring of the characteristics of the substrate it should ... -
Remediaciòn de unsitio contaminado (Pertusola):modelaciòn del transporte subterraneo Y anàlisis de riesgo sanitario
