Synthesis and characterization of nanomaterials: graphene, silicene and carbon nano- onions
(2017-10-20)
The electronic structure of the graphene/Ni(111) system was investigated by means of electron energy-loss spectroscopy (EELS). A single layer of graphene has been obtained on Ni(111) by dissociation of ethylene. Angle-resolved ...
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 ...
Diffusion and implantation of dopants in single-wall carbon nanotubes:a spectroscopic investigation of chemical and electronic properties
(2012-11-09)
Raman measurements, performed on MWCNTs grown by arc discharge
method in He atmosphere, have pointed out the occurrence of a band at 1780-
1860 cm–1, regardless of the use of a catalytic Ni-Cr alloy in the synthesis ...
Three-Dimensional Hybrid Code for Earth's Magnetotail Dymamics
(2012-11-08)
This work is dedicated to the development and exploitation of a new threedimensional
(3D) particle code for equilibrium plasma con gurations. The
code is of the so-called hybrid type, that is ions are treated as particles ...

Nanostructured Soft Matter: Mirror-less Lase
(2014-05-26)
Adsorption properties of carbon nanotubes and application of thermal desoprtion spectroscopy to ammonia and methane ices and zoisite
(2014-05-15)
In this work we wanted to underline the importance of Thermal Desorption Spectroscopy and its applications to several branches of Physics.
Temperature-programmed desorption techniques (TPD) are important to determinate ...
Remediaciòn de unsitio contaminado (Pertusola):modelaciòn del transporte subterraneo Y anàlisis de riesgo sanitario
(2009)
This work applies deterministic and probabilistic methodology to the analysis of health risk of a contaminated site. The risks we have calculated are both cancerogenous and no-cancerogenous. The area we studied was formerly ...
