A cyano-bridged bimetallic ferrimagnet: Synthesis, X-ray structure and magnetic study
2010
Mixing of trans-[Mn(cyclam)Cl2]Cl (cyclam = 1,4,8,11-tetraazacyclotetradecane) and potassium hexacyanochromate (K3[Cr(CN)6]) aqueous solutions instantaneously yields a 1D infinite chain complex {[Mn(cyclam)(l-CN)2Cr(CN)4]� H2O}n (1). The crystal structure of 1, crystallizing in the monoclinic system with space group P21/n has been solved from X-ray powder diffraction data following direct space approach and refined by the Rietveld method. The structure analysis of 1 reveals alternating [Cr(CN)6] 3� and [Mn(cyclam)] 3+
From recovery manuals to historic and construction building information modeling (h-BIM). Strategies for historical Sicilian centres
2018
Il recupero dei centri storici costituisce oggi, oltre che un obiettivo prioritario di qualsiasi politica urbana, anche una attività di grande interesse strategico ed economico. Molte sono state le ricerche e le politiche di sostegno concernenti interventi sull’esistente, dettate da una sensibilità per il recupero del patrimonio edilizio della città storica; ciò ha reso necessario l'analisi e lo studio specifico delle tecniche costruttive. Nonostante il complesso quadro normativo e vincolistico, gli interventi sui centri storici continuano però ad essere in molti casi condotti in maniera impropria. L’uso di materiali e tecniche incolte, trasferite dal cantiere moderno a quello di recupero, …
BIM Modelling of Ancient Buildings
2018
In the last years, new procedures on design and management of constructions, based on 3D standardised models of building elements, have been proposed. It’s the case of Building Information Modelling (BIM) applications, that, differently from CAD ones, allow to work with libraries of 3D parametrical objects (smart objects) describing geometric, structural and material properties of building elements. This methodology is based on the Industry Foundation Classes (IFC) model, that represents a global standard for the building data exchange. Initially used for the design of new architectures, BIM methodology has been even more considered also for the management and the conservation of historical…
AHBIM for Wooden Built Heritage Conservation
2019
The chapter investigates the potential offered by the Building Information Modeling for the conservation of the wooden architectural heritage. Based on the architectural survey, the BIM modeling of a South Tyrolean farm was carried out, with particular attention to the aspects related to its management and maintenance. Inside the database connected to the model, information about the building has been included, which can also be used on site through the use of mobile devices. The sharing of such information within a single platform avoids risks connected to the failure or incorrect transmission of data, allowing the optimization of the management, maintenance and conservation of the archite…
Confronto TAC – MRI per lo studio della cinetica di assorbimento dell’acqua in materiali lapidei
2007
Vengono messe a confronto due tecniche, la Risonanza Magnetica (MRI) e la tomografia assiale computerizzata (TAC), per ottenere informazioni quantitative sulla cinetica di assorbimento dell’acqua in sezioni interne di materiali lapidei. Entrambe le tecniche permettono di studiare adeguatamente il fenomeno. Nel caso in cui si formi un fronte di bagnamento, come per la Pietra di Lecce, l’analisi delle immagini consente di determinare in modo quantitativo l’altezza di risalita in funzione del tempo ed i dati possono essere interpretati alla luce del modello di Washburn per l’assorbimento capillare. Nel caso in cui il fronte non si formi, come per campioni di biocalcareite provenienti da una ca…
Aurophilicity as a cofactor in crystal engineering. Dicyanoaurate(I) anion as a building block in a novel Co(II)–Au(I) bimetallic assembly
2002
A 2D grid-shaped cyanide-bridged Co(II)–Au(I) bimetallic coordination polymer, [Co(DMF)2{Au(CN)2}2], has been prepared from the [Au(CN)2]2 building block; sheets associate pair-wise by aurophilic interactions and the compound exhibits zeolite-like properties.

Cinetica di assorbimento dell’acqua tramite NMR Imaging per la valutazione della efficacia di trattamenti idrorepellenti
2007
L'efficacia dei trattamenti normalmente impiegati per proteggere e/o consolidare materiali lapidei può essere valutata mediante la tecnica di imaging a risonanza magnetica nucleare (MRI), che consente di studiare in modo quantitativo, non invasivo, non distruttivo, la cinetica di assorbimento capillare dell'acqua. In campioni omogenei (Pietra di Lecce) si forma un fronte piatto (con una discontinuità netta alla scala di misura) e la tecnica MRI permette di seguire la cinetica in quanto consente di misurare, in funzione del tempo, l'altezza raggiunta da tale fronte in qualunque sezione interna del campione. Vengono confrontati i risultati ottenuti sullo stesso litotipo utilizzando due divers…
Exemple du projet Arena Naterre
2014
L’article traite de façon technique le travail réalisé sur le projet Arena Nanterre (projet de Christian de Portzamparc) à Paris dans le cadre d’une mission de BIM (Building Information Model). Notre engagement était d’aider tous les intervenants à concevoir et construire autrement le bâtiment grâce à la maquette numérique. Celle-ci a évolué et a été mise à jour tout au long des études pour permettre, d’un côté, un partage réel et instantané des informations et, de l’autre, une optimisation du projet en termes techniques, économiques ou encore de gestion. L’organisation mise en place a permis de créer une plateforme collaborative dans laquelle nous étions en charge de la gestion BIM de tout…
VIRTUAL REALITY AND BIM FOR INFRASTRUCTURES
2023
Abstract. Building Information Modelling (BIM) has been widely adopted in the construction industry as a means of improving project efficiency, reducing errors, and facilitating collaboration among stakeholders. However, its potential for the infrastructure sector has not been fully explored. Infrastructure projects, such as roads, bridges, tunnels, and airports, are often complex and require the integration of multiple systems and disciplines. BIM has the potential to provide a digital representation of the infrastructure project, allowing for improved design, construction, and maintenance. This paper aims to explore the potential benefits of BIM in the infrastructure sector, examine the c…
ISIM - INFRASTRUCTURES & STRUCTURES INFORMATION MODELING: A NEW CONCEPT OF BIM FOR INFRASTRUCTURES
2023
The application of Building Information Modeling (BIM) in infrastructure and structural projects, known as Integrated Structural and Infrastructure Modeling (ISIM), has gained attention in recent years due to its potential to revolutionize the construction industry. By providing a digital representation of the built environment, BIM allows for improved collaboration and communication between project stakeholders, leading to enhanced project outcomes. The ISIM approach is centered on the creation of a digital twin, a three-dimensional model of the infrastructure or structure, which serves as a virtual replica of the physical asset. This digital twin provides a platform for analysis, decision…
