Note sulle arti decorative a Malta. Inediti argenti siciliani di inizio XIX secolo.
2015
L’articolo si occupa di preziosi e inediti argenti siciliani di inizio Ottocento (ante 1826/1829), tra Rococò e Neoclassicismo, che si trovano a Malta. La maggior parte di essi recano il marchio consolare della città di Catania e sono stati realizzati negli anni 1810-1812. The article deals with precious and unpublished Sicilian silverware of the early nineteenth century (ante 1826/1829), between Rococo and Neoclassicism, that are located in Malta. Most of them bear the consular city mark of Catania and were made in the years 1810-1812.
Introduction: Situating the Human in Social Robots
2015
Traditionally the social has been considered as a characteristic of human beings, not of inanimate machines. At the same time, each technological device can be considered social born out of a complex process of invention, implementation, distribution and domestication by users (Hirsch and Silverstone 2004; Lasen 2013). Since recent technical developments have made possible rather detailed technical mimicking of human beings and their social features, and incorporating them in silicon chips, there is a pronounced need to understand to what extent the humanness can be implanted in social robots. This is also an occasion to think over and discuss what the human is when considered in this conte…
Float glass colouring by ion exchange
2008
Abstract Back in the Middle Ages, glass artists used to produce yellowish colorations in soda-lime glasses using mixtures that contained silver salts, clay composites and natural oils. The resulting colour was a characteristic pale yellow known as silver-stain. This coloration is mainly caused by the extinction – absorption and, to a lesser extent, scattering – of light occasioned by silver nanoparticles formed inside the glass. This colouring technique comprises a heat treatment divided in two stages: in the first one, an ion exchange between the silver ions in the mixture and the alkali ions in the glass takes place. This process is called nucleation of silver nanoparticles. The second st…
TCO/Ag/TCO transparent electrodes for solar cells application
2014
Among transparent electrodes, transparent conductive oxides (TCO)/metal/TCO structures can achieve optical and electrical performances comparable to, or better than, single TCO layers and very thin metallic films. In this work, we report on thin multilayers based on aluminum zinc oxide (AZO), indium tin oxide (ITO) and Ag deposited by RF magnetron sputtering on soda lime glass at room temperature. The TCO/Ag/TCO structures with thicknesses of about 50/10/50 nm were deposited with all combinations of AZO and ITO as top and bottom layers. While the electrical conductivity is dominated by the Ag intralayer irrespective of the TCO nature, the optical transmissions show a dependence on the natur…
