Effectiveness and Compatibility of Nanoparticle Based Multifunctional Coatings on Natural and Man-Made Stones

چکیده
The interaction of microorganisms with stone materials leads to biodeterioration processes, which may cause aesthetic damages and the loss durability strength substrates. Innovative solutions against this process are represented by nanotechnologies. In our previous works, 2-mercaptobenzothiazole was successfully encapsulated within two silica-based nanodevices: nanocapsules mesoporous nanoparticles. Such loaded nanodevices have been dispersed in TEOS based coatings, characterized as far their chemical–physical properties vitro biocide efficacy. Here, we adopt a multi-technic approach, assess coatings efficacy compatibility four types stones cultural heritage interest, namely, mortar, brick, travertine, Carrara marble. particular, determine protective function on water transport (reduction up factor 10 absorption for brick without significantly influencing vapor transmission rate), morphology surface (absence coating cracks color changes), TiO2 photocatalytic activity. Consequently, these can be considered suitable application artifacts, interfering artistic appearance.

Entropy-based Serviceability Assessment of Water Distribution Networks, Subjected to Natural and Man-Made Hazards
In this study a modified entropy-based measure is presented for evaluating the serviceability level of water distribution networks in which the hydraulic uncertainties (flow rates in pipes) as well as the uncertainties due to mechanical parameters (failure probabilities of links) are considered simultaneously. In the proposed entropy calculation method, the connectivity order of the network dem...

15 صفحه اولTerrestrial Natural and Man-made Electromagnetic Noise
The terrestrial environment is continuously exposed to electromagnetic radiations which set up a “background” electromagnetic noise. For what concerns electromagnetic waves in the Non Ionizing Radiation band (NIR), i.e. for frequencies lower than 300 GHz, the background can have a natural or an artificial origin. In the first case electromagnetic radiations have generally an atmospheric or a co...
