Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica

Recombinant mussel protein Pvfp5β enhances cell adhesion of poly(vinyl alcohol)/k-carrageenan hydrogel scaffolds

2022

Polymeric hydrogels are increasingly considered as scaffolds for tissue engineering due to their extraordinary resemblance with the extracellular matrix (ECM) of many tissues. As cell adhesion is a key factor in regulating important cell functions, hydrogel scaffolds are often functionalized or loaded with a variety of bioactive molecules that can promote adhesion. Interesting biomimetic approaches exploit the properties of mussel-inspired recombinant adhesive proteins. In this work, we prepared hydrogel scaffolds with a 50%w mixture of k-carrageenan (kC) and polyvinyl alcohol (PVA), by a two-step physical gelation process, and we coated them with Perna viridis foot protein-5 beta (Pvfp5 be…

Collecte des données Véhicule/Environnement et remontée avec réseau Cellulaire et réseau Véhiculaire

2019

Vertical handover is one of the key technologies that will facilitate the connected and autonomous vehicles deployment. Today, the emergence of Vehicular Ad hoc Networks (VANETs): Vehicle-to-Vehicle (V2V) communications, Vehicle-to-Infrastructure (V2I) and Vehicle-to-Everything (V2X) has enabled new applications such as Cooperative Intelligent Transport Systems (C-ITS), real-time applications (for example, autonomous driving), road traffic management applications and comfort applications. However, these networks are characterized by a high level of mobility and dynamic change in the topology, which generates scattered networks and requires handover mechanisms for maintaining ongoing session…

“Building Integrated Photovoltaics and DSSC-Glassblocks"

2012

According to many market analysts, Building Integrated Photovoltaics (BIPV) represents the future of photovoltaic (PV) industry as well as one of the strategies for the achievement of zero-energy building standards and UE goals for the next years. Dye-sensitised solar cell (DSSC) is a low-cost and very versatile solar technology, offering a wide range of possibilities in terms of colour, transparency and design: hence DSSC are particularly suited for BIPV and could give a big contribution in this direction. Starting from those considerations, this paper will show the first results of a research aimed at the integration of DSSC with the glassblock for the construction of multifunctional tran…

Valencia Semanal (1977-1980). D’altaveu valencianista contra el postfranquisme a centre de les pugnes internes del PSPV-PSOE

2014

Els últims anys de la dècada dels setanta i els primers anys dels huitanta convertiren el País Valencià en un cas paradigmàtic de molts dels mals de la Transició espanyola, amb estratègies polítiques basades en la por i la violència, lluites internes dels partits que acabaren per perjudicar el procés autonòmic de consecució de l’Estatut o el final de l’època d’idealismes i l’asseveració que la nova democràcia anava a caracteritzar-se pel pragmatisme polític i l’aniquilació programada de les mobilitzacions ciutadanes. Tot va quedar recollit als mitjans de comunicació de l’època, però no a tots. Sols a aquells que volgueren prendre part en el “conflicte”, que veieren en la crisi l’oportunitat…

Histological features and ki-67 index in cervical atypical lesions

2008

One of the most frequent challenges in routine diagnostic assessment of cervical biopsies consists of some lesions in which histological features of HPV infection are either inconsistently present or only mildly/focally evident. We named them Atypical Lesions (AL) because differential diagnosis with metaplastic/reactive lesions and LSIL is difficult. It would be important to identify among them those lesions that are really HPV-associated. We studied 52 AL cases to evaluate whether the morphological features and the proliferation index, assessed by Mib1 (Ki67) immunostaining, would be useful to better understand the real nature of AL, with relation to the HPV presence and to the proliferati…
