Film di ZnO drogati di tipo p per diffusione termica di atomi di fosforo da substrati di InP
2012
We report on p-type doping of ZnO films grown by pulsed-laser deposition on InP substrates. Electrical properties change of the films, from n-type to p-type, has been observed after postgrowth annealing at 600°C for 1h in air.

Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equil…
2016
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, and system dimensionality and size. In many regimes, we find significant improvement over adiabatic time dependent density functional theory or second Born nonequilibrium Green's function approximations. We briefly discuss the reasons for the residual discrepancies, and directions for future work.
DFT Prediction of Enhanced Reducibility of Monoclinic Zirconia upon Rhodium Deposition.
2018
Oxides are an important class of materials and are widely used, for example, as supports in heterogeneous catalysis. In a number of industrial catalytic processes, oxide supports actively participate in chemical transformations by releasing lattice oxygen anions. While this is intuitively understood for reducible oxides, the reducibility of irreducible oxides may be modified via nanoengineering or upon inclusion of foreign species. Our calculations predict that the ability of irreducible monoclinic zirconia to release oxygen improves substantially upon deposition of rhodium. Through a comprehensive screening of Rh/ZrO2 with different size of the rhodium species, we find that a Rh adatom and…
L'importanza del paesaggio residuale e del verde nella ridefinizione dello spazio Pubblico dell'abitare

Les cités des Eduens et de Chalon durant l'Antiquité tardive (v. 260-530 env.). Contribution à l'étude de l'Antiquité tardive en Gaule centrale.
2005
This research deals with the evolution of two of the main ciuitates of the Lugdunensis prima province. It explores their territorial organisation, social and economic structures between the emergence of the Gallic Empire (260 AD) and the end of the kingdom of the Burgundians (530 AD).After tackling the methodological, archeological and historical issues raised by the study of the two ciuitates, it focuses on the city of Autun, on its small neighbouring towns (including Chalon), rural areas and religious practices. The last part is a synthesis of the data, which is set in a historical and chronological framework. This part aims at highlighting the different stages of social developments in t…

Testing of Virtual Toolkit with Stakeholders
2022
The collected data reported in this document gives mainly positive feedback on Virtual Toolkit (IO2), highlighting some interesting and relevant elements that can be further developed in its final release. The group of respondents have a quite long average experience in managing inter-institutional projects and belong to the EU-defined main participants groups of Managers (22), Teachers/Trainers/Researchers/Youth workers (17), Technicians (3) and Administrative staff (5). Of the 8 indicators outlined in the original ONE Meeting Project proposal, 5 were met, 3 not. The 4 reached indicators were Usefulness & Relevance, Impact on Virtual Transnational Collaboration, Willingness to recommend to…
Signed, Sealed, and Delivered with Trust: Non-Resident Citizens’ Experiences of Newly Adopted Postal Voting
2021
The COVID-19 pandemic has made it clear that the traditional “booth, ballot, and pen” model of voting, based on a specific location and physical presence, may not be feasible during a health crisis. This situation has highlighted the need to assess whether existing national electoral legislation includes enough instruments to ensure citizens’ safety during voting procedures, even under the conditions of a global pandemic. Such instruments, often grouped under the umbrella of voter facilitation or convenience voting, range from voting in advance and various forms of absentee voting (postal, online, and proxy voting) to assisted voting and voting at home and in hospitals and other healthcare …
