Investigation of chemical, physical and mechanical properties of hybrid chitosan-silica based coatings for aluminium substrate

This paper describes the development and characterization of eco-friendly hybrid coatings using chitosan and tetraethoxysilane (TEOS) through sol-gel processing onto aluminium substrates. Firstly, we investigated the impact of curing temperatures and the addition of a coupling agent (VTMS) on various physical and chemical properties to determine the optimal composition, to achieve crack-free and uniform films. Chemical and physical properties were assessed via FTIR spectroscopy and SEM imagin...

Vitruvian binders in Venice: First evidence of Phlegraean pozzolans in an underwater Roman construction in the Venice Lagoon

: Four mortar samples were collected from a submerged Roman well-cistern (1st c. CE) in the Northern part of the Lagoon of Venice, recently investigated during underwater surveys promoted by the team of maritime archaeology of the University Ca' Foscari of Venice. Samples were preliminary described following a standardized protocol of analytical techniques, including Polarized Light Optical Microscopy (PLM), Quantitative Phase Analysis-X-Ray Powder Diffraction (QPA-XRPD) and Scanning Electron...

Spiritual Technologies: The Religious Symbolism of the Digital Universe

This essay attempts to analyse the discourses, gestures and projects of the new digital galaxy’s protagonists who conceive their mission in fundamentally religious terms. It will also aim to trace the intellectual genealogy and conceptual premises of their cultural and communicative vision. This analysis will attempt to define four ideal types based on reference figures taken from mythology and religion as well as the imaginary of contemporary popular culture: Prometheus, Moses, Hermes Trism...
