Physical and Chemical treatments to produce graphene and their related applications
(2016-02-26)In this work Few Layers Graphene (FLG) and Graphene Oxide (GO) were produced by using physical and chemical treatments, and two types of applications were tested with GO. The first application concerns the Drug delivery ... -
Physical processes in single and multiple photons additive nano-manufacturing of three-dimensional polymeric and metallic structures for advanced optics
(2018-04-04)In the field of nanotechnologies the Two-Photons Direct Laser Writing (TP-DLW) is the most advanced optical technique for creating arbitrarily complex 3D structures in organic resists, featuring details down to 50 nm, well ... -
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 ...
