Impact of Different Washing Conditions on the Release of Ag Species from Textiles
2016
The paper investigates the Ag release from textiles (socks available in shops, cotton and viscose filled with Ag nanoparticles–AgNPs) into a washing solution under different conditions. The released Ag amount depended on various factors, such as test media (chemical composition, temperature and water volume), metal contents, and textile impregnation conditions. Furthermore, it turned out that the textile type and colour were the main parameters affecting the Ag release. The Ag concentration in the washing solution ranged between 0.015 μg/l and 4.44 μg/l (socks) and between 0.61 μg/l and 103 μg/l (AgNPs–filled cotton). The total Ag percentage released into water during one washing varied con…
Thermo-Mechanical Behaviour of Flax-Fibre Reinforced Epoxy Laminates for Industrial Applications
2015
The present work describes the experimental mechanical characterisation of a natural flax fibre reinforced epoxy polymer composite. A commercial plain woven quasi-unidirectional flax fabric with spun-twisted yarns is employed in particular, as well as unidirectional composite panels manufactured with three techniques: hand-lay-up, vacuum bagging and resin infusion. The stiffness and strength behaviours are investigated under both monotonic and low-cycle fatigue loadings. The analysed material has, in particular, shown a typical bilinear behaviour under pure traction, with a knee yield point occurring at a rather low stress value, after which the material tensile stiffness is significantly r…
The museum setup in the benedictine dormitory of monreale: The artworks of Santa Maria Del Bosco and the textile artefacts of the Cathedral, Sicily, …
2018
The recent decision to convert the Benedictine Dormitory in Monreale into an exhibition site offers the opportunity to enjoy the whole monumental complex where the wonderful cloister is the core attraction. It is on this site that the Norman Cathedral stands, brightly decorated with golden mosaics. The new exhibition has gathered together the artworks from the ruined abbey of Santa Maria del Bosco in Calatamauro and added them to the artefacts already exhibited at the Diocesan Museum. They include marble gravestones from the 16th-17th century church and those dating to the 18th century; one stone is in polychrome marble of the family of the canons, Candes and Donato; another was used for th…
Universities’ “Third” Mission, Industrial Conversion and the Quest for Surgical Masks: A Sicilian Tale from the First COVID-19 Lockdown
2022
This contribution is a brief testimony of a “third mission” project conducted in collaboration by two university departments that, despite the operational difficulties, and thanks to institutional support, have promoted an initiative aimed at the productive reconversion of a clothing sector company into a health sector company. The project highlights the benefits of integrating different areas of scientific expertise and highlights the role of full involvement and co-creation of a new production unit. Moreover, it is an example of the role that the university can play in a complex operational context in support of a constructive relationship between public and private actors for the develop…
Rigenerazione dell’area dell’ex fabbrica tessile Gulì a Palermo
2018
L’attività industriale palermitana, pur avendo vissuto un periodo fiorente piuttosto breve, ha lasciato tracce ben riconoscibili e identificabili all’interno del tessuto urbano, con manufatti architettonici di notevole importanza per qualità di progetto e dimensioni. L’ex fabbrica tessile Gulì è un complesso interessante sia dal punto di vista architettonico sia per la sua localizzazione urbanistica, molto prossima a poli di rilevante interesse culturale. Lo studio, condotto presso il Dipartimento di Architettura dell’Ateneo di Palermo, propone un intervento di rigenerazione che coinvolge non solo i manufatti edilizi presenti ma l’intera area e la sua trasformazione in un nuovo centro di qu…
