Abstract:
This thesis explores the synthesis and characterisation of a range of molecular wheels containing unpaired electron spins. These molecular spin systems are of considerable interest, both for the insight they provide into the physics of such systems and for their potential as quantum bits ("qubits") in a quantum information processing device. In particular, this thesis explores using these wheels to meet criteria 1 and 5 of the DiVincenzo criteria. The synthesis of a novel homometallic and nonametallic ring of CrIII ions is introduced, along with extensive physical characterisation. Inelastic N

Abstract:
Nuclear magnetic resonance (NMR) spectroscopy has been extensively used to investigate the structure and dynamics of host-guest systems. NMR spectroscopy has gained attention because of its high spectral information content for studies of molecules in the solid state and in solution. However, the main weakness of NMR is the inherent low detection sensitivity. Host-guest interactions are weak; therefore these interactions can be particularly difficult to study due to weak spectral response. NMR methods are currently the best solution for measuring these responses with atomic-scale precision

N-Cadherin plays an important role during dendrite arborisation, axon guidance and synaptogenesys. In particular, at synaptic sites, it is required for activity-dependent synaptic plasticity and dendritic spine remodeling. Recent studies have shown that N-Cadherin can be cleaved by the metalloproteinase ADAM10. Here we demonstrate that modulating ADAM10 localization and activity at synaptic sites regulates its processing of N-Cadherin. This indices modification of dendritic spines morphology and of composition and function of AMPA receptors. In particular, inhibition of ADAM10 synaptic locali

In the central nervous system, chemical synapses are highly specialized junctions that are known to be critical for communication between neurons. The ability of synapses to change their physiological and structural properties, known as synaptic plasticity, is important for storing information in neural connections. Dendritic spines are small protrusions on dendrites where the majority of glutamatergic synapses form in the brain. In general, a dendritic spine has an enlarged head region that is connected to the dendritic shaft by a narrow neck. This geometry allows spines to function as indivi

Abstract:
Wave-like phonons are often used to describe the heat capacity in materials. In this report the spin-phonon interaction between nuclei in a diatomic molecular structure is introduced by looking at the Hamiltonian in its ground state. The corresponding Green's functions are computed in order to investigate how this interaction affects the phonons. When calculating the spin, pseudo fermions and tensor products are introduced to make the calculation easier because the spin statistics could be a bit tricky to deal with. Three different cases of how the total interaction Hamiltonian behaves are inv

Abstract:
L'utilisation de matériaux organiques pour l'électronique de spin suscite actuellement un fort intérêt. En effet, le long temps de diffusion de spin, la possibilité de manipuler l'état de spin d'une molécule ainsi que son interaction avec une surface magnétique offrent a priori de nouvelles possibilités pour la réalisation de nouveaux dispositifs d'électronique de spin. L'incorporation dans des dispositifs de molécules possédant deux états de spin nécessite la compréhension du phénomène de transition de spin une fois que les molécules sont en contact direct avec des surfaces métalliques.L'obje
