Il contributo sociale delle superfici vetrate.
2014
Oggi la domanda abitativa è cambiata, non solo negli aspetti quantitativi ma soprattutto nella dimensione qualitativa. Nel tempo, in relazione a fenomeni di carattere sociale ancor prima che economico, sono cambiate le categorie sociali più deboli, ora rappresentate soprattutto dagli anziani. Inoltre, in relazione all’innalzamento della soglia di mortalità, si assiste a un progressivo e costante aumento dei casi di demenza senile, un disturbo delle funzioni intellettive in precedenza acquisite quali la memoria a breve e lungo termine, il pensiero astratto, la capacità critica, il linguaggio e l’orientamento spazio temporale. L’ampia e crescente diffusione nella popolazione, la limitata e co…
Valeria Tatano e AA. VV. Oltre la trasparenza.
2012
Recensione del testo di VALERIA TATANO (CURATORE), Oltre la trasparenza. Riflessioni sull’impiego del vetro in architettura, Officina, Roma 2008. La storia del vetro in edilizia coincide con la ricerca della trasparenza: grazie al vetro la luce può entrare negli ambienti che, al tempo stesso, sono protetti dagli agenti atmosferici. Negli ultimi anni, con l’evoluzione tecnologica, abbiamo assistito a una rivoluzione delle possibilità di impiego di tale materiale. Il testo Oltre la trasparenza offre uno scenario completo sui possibili usi innovativi del vetro nell’architettura contemporanea; obiettivo dell’articolo è quello di evidenziare i caratteri essenziali di tale evoluzione.
Biodeterioration of the Wooden Roof of the Phnom Penh National Museum
2017
Within the framework of a training program in Cambodia, during a visit to the National Museum in Phnom Penh, the most important in the Kingdom of Cambodia, the authors noted the presence of some signs of a termite attack in the secondary elements of the roof of an inner garden. Following this observation, a further investigation was performed in order to evaluate the phytosanitary condition of the wooden bearing element of the roof. The inspection highlighted the presence of severe decay, constituting a real danger for the integrity of the roof; consequently, an intervention of restoration, conservation and safeguard was considered to be necessary and urgent. This paper presents the results…
Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light
2017
Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…
Innovative Approaches for Organizing an Inclusive Optics and Photonics Conference in Virtual Format
2023
The COVID pandemic is forcing the renewal of scientific conferences, offering opportunities to introduce technological and inclusive developments. Our analysis focuses on the implementation of inclusive practices for female and early-career researchers in a virtual scientific conference. This organization approach was applied in the XIII Spanish Optical Meeting (RNO2021), which was also characterized by avatars interacting in an online metaverse. The effectiveness of inclusive policies and novel technological tools was evaluated using the participation data and a post-conference survey. Our study reveals the high impact of inclusive actions and a strong interest in the scientific community …
