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 ... -

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 ... -
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 ... -
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 ...
