Unravelling the Photocatalytic Behavior of All-Inorganic Mixed Halide Perovskites: The Role of Surface Chemical States
2019
Within the most mesmerizing materials in the world of optoelectronics, mixed halide perovskites (MHPs) have been distinguished because of the tunability of their optoelectronic properties, balancing both the light-harvesting efficiency and the charge extraction into highly efficient solar devices. This feature has drawn the attention of analogous hot topics as photocatalysis for carrying out more efficiently the degradation of organic compounds. However, the photo-oxidation ability of perovskite depends not only on its excellent light-harvesting properties but also on the surface chemical environment provided during its synthesis. Accordingly, we studied the role of surface chemical states …
Vacuum Processed Narrow and Wide Bandgap Perovskites for Photovoltaic Applications
2021
El objetivo principal de la presente tesis fue el desarrollo de nuevos materiales que sirvan de ayuda en la actual emergencia climática. De este modo, se prepararon perovskitas de banda prohibida estrecha y ancha con la intención de integrarlas en tándems, que pueden aprovechar todo el espectro solar para generar energía, en el futuro. Las perovskitas fueron preparadas mediante la técnica de sublimación, o deposición a vacío. Además, se emplearon otras técnicas que no requieren del uso de disolventes, como la mecanoquímica. A lo largo de la tesis se preparan dos perovskitas de banda prohibida estrecha, siendo una de ellas la primera perovskita basada en plomo y estaño sintetizada mediante s…
Le innovazioni del piano provinciale: una questione di metodo

Metodologie di rilievo metrico e diagnosi materica in edifici storici. Casi studio.
2010
Ancora oggi manca una codificazione di regole da suggerire perché vengano seguite con puntualità per ripristinare e per risanare i monumenti e gli edifici di interesse storico risalenti ai primi anni del secolo scorso, realizzati in calcestruzzo o contenenti parti ornamentali ma anche funzionali in calcestruzzo. E’ prevalsa l’abitudine di trattare questi ultimi come se fossero costruiti secondo le regole dell’odierna tecnica delle costruzioni, senza considerare dunque le differenti caratteristiche che essi presentano a partire dalle metodologie utilizzate per la produzione dei materiali, fino ad arrivare alle differenze di calcolo progettuale. Se da un lato dunque sembra corretto l’utilizzo…

Ordinary Muon Capture on 136Ba : Comparative Study Using the Shell Model and pnQRPA
2023
In this work, we present a study of ordinary muon capture (OMC) on 136136Ba, the daughter nucleus of 136136Xe double beta decay (DBD). The OMC rates at low-lying nuclear states (below 1 MeV of excitation energy) in 136136Cs are assessed by using both the interacting shell model (ISM) and proton–neutron quasiparticle random-phase approximation (pnQRPA). We also add chiral two-body (2BC) meson-exchange currents and use an exact Dirac wave function for the captured s-orbital muon. OMC can be viewed as a complementary probe of the wave functions in 136136Cs, the intermediate nucleus of the 136136Xe DBD. At the same time, OMC can be considered a powerful probe of the effective values of weak axi…
Considerazioni Critiche e di Prospettiva sulle Misure Provvisorie della Corte Internazionale Di Giustizia nel Caso Gambia c. Myanmar
2021
L’ordinanza adottata dalla Corte internazionale di giustizia il 23 gennaio 2020, in risposta alla richiesta di misure provvisorie presentata nell’ambito della controversia Gambia c. Myanmar e relativa alla presunta violazione della Convenzione per la prevenzione e la repressione del delitto di genocidio, contiene diversi spunti interessanti che, probabilmente, incideranno sulla prosecuzione del giudizio. Il presente scritto esamina le questioni procedurali e sostanziali che emergono dalla medesima. Quanto agli aspetti procedurali, ci si soffermerà, in particolare, sul locus standi dinnanzi alla Corte di uno Stato non direttamente leso da violazioni di obblighi erga omnes partes e sulle pros…
Tunteita herättävät pojat yhteisöllistä oppilashuoltoa toteuttavien ammattilaisten diskursseissa
2016
Laitinen, Taina. 2016. Tunteita herättävät pojat yhteisöllistä oppilashuoltoa toteuttavien ammattilaisten diskursseissa. Erityispedagogiikan ja sosiaalityön pro gradu -tutkielma. Jyväskylän yliopisto. Kasvatustieteiden laitos. Yhteiskuntatieteiden ja filosofian laitos. 89 sivua. Tutkimuksen tavoitteena oli kuvata yhtenäisperuskoulun ammattilaisten vuorovaikutusta sekä tarkastella kriittisesti heidän tapaansa puhua tunteita herättävistä pojista. Tutkimuksessa selvitettiin, millaisia identiteettejä tunteita herättäville pojille rakentuu oppilas- ja opiskelijahuoltolain (1287/2013) mukaista yhteisöllistä oppilashuoltoa toteuttavien ammattilaisten puheessa. Lisäksi selvitettiin, millaiset puhee…
Toward Quaternary QCA : Novel Majority and XOR Fuzzy Gates
2022
As an emerging nanotechnology, quantum-dot cellular automata (QCA) has been considered an alternative to CMOS technology that suffers from problems such as leakage current. Moreover, QCA is suitable for multi-valued logic due to the simplicity of implementing fuzzy logic in a way much easier than CMOS technology. In this paper, a quaternary cell is proposed with two isolated layers because of requiring three particles to design this quaternary cell. Moreover, due to the instability of the basic gates, the three particles cannot be placed in one layer. The first layer of the proposed two-layer cell includes a ternary cell and the second one includes a binary cell. It is assumed that the over…
Platformed Interactions: How Social Media Platforms Relate to Candidate–Constituent Interaction During Finnish 2015 Election Campaigning
2020
Interaction between candidates and constituents via social media is a well-studied domain. The article takes this research further through a synthesis with platform studies, emerging scholarship that applies a critical perspective to the role of digital platforms in society. Examination of candidate–constituent interaction via Twitter and Facebook during the 2015 Finnish parliamentary elections revealed that the types of interaction differ between the two platforms: Facebook was used for formal campaigning and for praising and expressing support, while Twitter was utilized for information and for seeking and sharing opinions. An additional finding is that interaction approaches may be plat…
