An Easy Route Towards Regioselectively Difunctionalized Cyclens and New Cryptands.
2006
Reductive amination of various aldehydes with cyclen represents a very convenient method for the synthesis of a wide range of 1,7-difunctionalized cyclens, as well as new cryptands.

La ceramica sovradipinta bizantina di Gortina
2008
EMMA VITALE (2008). La ceramica sovradipinta bizantina di Gortina. p. 1-304, PADOVA:Aldo Ausilio Editore in Padova-Bottega d''Erasmo, ISBN: 978-88-6125-071-0 The Byzantine painted pottery from the Gortys excavations represents a new class among the painted pottery productions which spread over the Mediterranean basin since the end of the 6th century AD. The first finds came to light around the mid-fifties during the excavations in the Temple of Athena on the acropolis (Haghios Ioannis hill), but the greatest number of fragments comes from the upper town and, particularly, from the Byzantine quarter between the Pretorio and the Apollo Pythios temple: here, the finding of a ceramic factory si…

2-Methylresorcinarene: a very high packing coefficient in a mono-anion based dimeric capsule and the X-ray crystal structure of the tetra-anion
2016
Mono- and tetra-deprotonated 2-methylresorcinarene anions (1 and 2) as their trans-1,4-diammoniumcyclohexane (TDAC)2+ inclusion complexes are reported. The mono-anion forms a fully closed dimeric capsule [1·H2O·MeOH]22− with a cavity volume of 165 Å3 and (TDAC)2+ as the guest with an extremely high packing coefficient, PC = 84.2%, while the tetra-anion forms a close-packed structure with two structurally isomeric tetra-anions 2a and 2b with a 50 : 50 ratio in the crystal lattice. peerReviewed
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…

Consumir la obra de terra. Los orígenes de la cerámica valenciana por el lado de la demanda (1283-1349)
2018
The origins of Valencian ceramic tableware, one of the most coveted products of the Late Middle Ages, have traditionally been explained from the supply perspective. The attention given to technological and stylistic–i.e. productive–aspects has tended to eclipse the issues that go beyond the objects themselves and affect the viewpoint of the consumer: to what extent was the demand for obra de terra by Valencian society key to the start of its production? This essay considers this matter using a sample of 232 probate inventories from between 1283 and 1349, to which will be applied quantitative analysis based on the historiography of consumption. It will be argued that, before the Black Death,…
