Luminescence properties of neodymium-doped yttrium aluminium garnet obtained by the co-precipitation method combined with the mechanical process
2005
Nanopowders of yttrium aluminium garnet Y3Al5O12 (YAG) doped with neodymium ions were obtained by the co-precipitation method from the reaction of aluminium and yttrium nitrate and neodymium oxide with ammonia. After washing and drying the hydroxide precursors were calcined at 500, 700, 800 and 900 °C for 1 hour and at 1000 °C for 3 hours. This product was treated by ball milling in a zirconia vial for 0.5, 1.5 and 10 h in order to achieve smaller nanoparticles. The structure, microstructure, morphology and optical properties were investigated by means of diffractometric, microscopic and spectroscopic techniques. The course of the amorphous-to-crystalline transformation was complete after c…

Sistemi di tariffe di cubatura per le fustaie di pino d'Aleppo, pino laricio e pino domestico della Sicilia
2009
Obiettivo del presente lavoro e la messa a punto di sistemi di tariffe validi per la cubatura delle masse legnose dei principali soprassuoli di conifere della Sicilia: in particolare, i sistemi proposti si basano sull’elaborazione delle serie di inquadramento delle relazioni ipsodiametriche per il pino domestico, il pino d’Aleppo e il pino laricio. Per ciascuna specie e stato studiato l’andamento della distribuzione dei valori ipsodiametrici, risultato ben rappresentato da una forma funzionale di tipo semilogaritmico utilizzabile come «curva guida» delle serie di inquadramento delle relazioni ipsodiametriche. Adottando l’inclinazione stimata in base alla curva guida e adattando le singole s…

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…
Paramagnetic Defects and Thermoluminescence in Irradiated Nanostructured Monoclinic Zirconium Dioxide
2022
The work was carried out under the grant of the Ministry of Education and Science of the Republic of Kazakhstan AP09260057, “Luminescence and radiation resistance of synthesized under different conditions micro- and nanostructured compacts and ceramics based on ZrO2”. The research was partly (A.I.P.) performed at the Center of Excellence of the Institute of Solid State Physics, University of Latvia, supported through European Union Horizon 2020 Framework Programme H2020-WIDESPREAD-01-2016-2017-TeamingPhase2, under grant agreement No. 739508, project CAMART2.
Periodontal Behavior Around Teeth Prepared with Finishing Line for Restoration with Fixed Prostheses. A Systematic Review and Meta-Analysis
2020
Background: The objective of this systematic review and meta-analysis was to analyze the periodontal behavior around teeth prepared with horizontal finishing crowns supporting fixed metal-ceramic and zirconia full coverage crowns and fixed partial dentures (FDPs). Materials and methods: An electronic search was conducted to locate relevant clinical trials in four databases: PubMed, Embase, Cochrane, and Scopus. A manual search was made in the reference sections of the articles identified for any additional articles. No restrictions were applied regarding year of publication or language. The following variables were considered in quantitative and qualitative analysis: probing pocket depth (P…
Il "genio" dal Trecento al Cinquecento
2008
Il concetto di genio si forma nella temperie romantica, ma le sue radici etimologiche affondano nell’antichità. Nel Medioevo (Dante, Petrarca, Boccaccio) la teoria dell’ingenium si articola in relazione al concetto di ars e non rinnega il rispetto delle regole. Nel Quattrocento la teoria platonica del furor divino dilaga nei versi e nelle trattazioni degli umanisti, quali Cristoforo Landino e Poliziano, mentre rimane estranea alle teorie artistiche, incentrate sul metodo razionale e sull’imitazione della realtà (Alberti, Leonardo), almeno fino al trattato sulla pittura di Francisco de Hollanda, in cui compare per la prima volta il concetto di genio creatore. Nei dibattiti del Cinquecento su…
