Desarrollo de modelos experimentales de LGMDD2 y rastreo de fármacos
2023
La distrofia muscular de cinturas tipo D2 (Limb-girdle muscular dystrophy type D2, LGMDD2) es una enfermedad genética ultra rara para la cual no existe tratamiento. Las principales características clínicas de la LGMDD2 son la debilidad y degeneración muscular progresiva que afecta a las cinturas pélvica y escapular de forma predominante. En 2013 se identificó la LGMDD2 como una miopatía autosómica dominante causada por una mutación en el gen de la transportina 3 (TNPO3), dando como resultado una proteína mutante con una extensión de 15 aminoácidos adicionales: TNPO3mut. TNPO3 es una β-importina responsable de la importación nuclear de proteínas ricas en serina/arginina (proteínas SR), invol…
La cuginanza. Storie esemplari di cugini dai Greci a Paperino
2022
Il saggio indaga in una prospettiva storico-linguistica e antropologica la natura del rapporto di cuginanza nella civiltà greca, proponendo confronti con la terminologia e la relativa concezione nel mondo latino. Al centro dell'indagine, condotta principalmente per un pubblico di non specialisti, c'è un ragionamento sulle occorrenze più antiche del termine greco "anepsiòs", esaminate nel loro contesto specifico all'interno, soprattutto, dei poemi omerici. Emerge la particolare natura del rapporto di cuginanza (termine attestato in greco nella forma anepsiòtes) secondo i Greci, che ne fa, specie nel caso di cugini primi, una fattispecie di parenti legati da uno stretto reciproco legame che i…
Applications and non-idealities of submicron Al–AlOx–Nb tunnel junctions
2016
We have developed a technique to fabricate sub-micron, 0.6µm×0.6µm Al-AlOx-Nb tunnel junctions using a standard e-beam resist, angle evaporation and double oxidation of the tunneling barrier, resulting in high quality niobium, as determined by the the high measured values of the critical temperature TC ∼ 7.5 K and the gap ∆ ∼ 1.3 meV. The devices show great promise for local nanoscale thermometry in the temperature range 1 - 7.5 K. Electrical characterization of the junctions was performed at sub-Kelvin temperatures both with and without an external magnetic field, which was used to suppress superconductivity in Al and thus bring the junction into a normal-metal-insulator-superconductor (NI…

Structural distortions in homoleptic (RE)4A (E = O, S, Se; A = C, Si, Ge, Sn): Implications for the CVD of tin sulfides
2001
The structures of Sn(SBut)4 and Sn(SCy)4 have been determined and adopt S4 and D2 conformations respectively; the anion [(PhS)Sn3]−, as its Ph4P+ salt, has a structure approaching Cs symmetry. In all three compounds, there are large variations in the ∠S–Sn–S within the same molecule, which have been rationalised in terms of the C–S–Sn–S–C conformations. For Sn(SR)4, the ∠S–Sn–S increases as the conformations change from trans, trans to trans, gauche and gauche, gauche, as the number of eclipsed lone pairs decreases and this rationale is shown to be applicable to a variety of A(ER)4 (A = C, Si, Ge, Sn; E = O, S, Se) and related [Mo(SR)4, Ga(SR)4−] systems. AM1 calculations have been used to …
Deposition of tin sulfide thin films from tin(iv) thiolate precursors
2001
AACVD (aerosol-assisted chemical vapour deposition) using (PhS)(4)Sn as precursor leads to the deposition of Sn3O4 in the absence of H2S and tin sulfides when H2S is used as co-reactant. At 450 degreesC the film deposited consists of mainly SnS2 while at 500 degreesC SnS is the dominant component. The mechanism of decomposition of (PhS)(4)Sn is discussed and the structure of the precursor presented.

High-quality superconducting titanium nitride thin film growth using infra-red pulsed laser deposition
2018
Superconducting titanium nitride (TiN) thin films were deposited on magnesium oxide, sapphire and silicon nitride substrates at 700 °C, using a pulsed laser deposition (PLD) technique, where infrared (1064 nm) pulses from a solid-state laser were used for the ablation from a titanium target in a nitrogen atmosphere. Structural studies performed with x-ray diffraction showed the best epitaxial crystallinity for films deposited on MgO. In the best films, superconducting transition temperatures, T C, as high as 4.8 K were observed, higher than in most previous superconducting TiN thin films deposited with reactive sputtering. A room temperature resistivity down to ~17 μΩ cm and residual resist…
