Synthesis of self-assembled mesoporous 3D In2O3 hierarchical micro flowers composed of nanosheets and their electrochemical properties
2018
This report describes the methodology for the fabrication of mesoporous In2O3 microflowers by hydrothermal and calcination procedures in which In(OH)3/In2S3 acts as an intermediate. Both In2O3 and its precursor were analyzed with scanning electron microscopy, energy dispersive X-ray spectrophotometry, transmission electron microscopy and powder X-ray diffraction. BET surface area, pore size and pore volume analyses were also carried out. Electron microscopy images clearly evidence the self-assembly of 2D nanosheets into the micro flower structure. The mechanism of self-assembly and calcination is reported. Electrochemical properties of the synthesized In2O3 micro flowers were studied. peerR…
Single-mode Bragg gratings in tapered few-modes and multimode fibers
2019
We propose the implementation of fiber Bragg gratings in tapered few-mode and multimode fibers to accomplish single-mode operation by reducing the core diameter, while preserving the core-cladding structure. The gratings present a single reflection band, and the device shows low insertion losses after the taper fabrication and the fiber Bragg gratings inscription. The excitation of high-order odd modes in the core of the fiber has been identified as the main loss mechanism; it can be prevented by means of symmetric illumination of the fibers. We also demonstrate the excitation of high-order cladding modes (cladding-air modes) along the taper transitions; these modes can be removed without a…
Predicting mechanical behaviour and damage kinetics of a 3D interlock composite materials by using a multiscale approach
2012
International audience; The present work aims to investigate the mechanical behaviour and the damage kinetics of a3D interlock woven fabric composite, especially used for natural gas tanks dedicated to thetransportation industry. On the one hand, we aim at predicting the macroscopic coefficients ofthe stiffness matrix by homogenization multiscale approach. For this, we identified a basicunit cell which represents well the composite microstructure. On the other hand, damagemechanisms are analyzed: optical microscopy examinations on damaged specimens revealedseveral types of defects. We used the same multi-scale approach to assess the impact of thesedefects on the decrease of stiffness.
TECHNOLOGICAL DESIGN. THE INNOVATION IN THE METHOD
2018
The book presents reflections on the centrality of Design in the discipline of Technology of Architecture and on the need to adapt the design method to the innovation of thought implemented by the research world. The theme of the Innovation in the Method of Technological Design is an interesting challenge that in this volume has been addressed considering the complexity of the levels of thematic depth, opening up to critical reflections, proposals for tools and illustration of case studies that show the breadth, relevance and multidimensionality of this issue. The era of digital and information technology have significantly influenced the way of doing and thinking in architecture and this e…
Looking ahead in games research
2021
This thematic issue presents a number of emerging scholarships into the study of digital gaming. The articles are based on a 2019 symposium on game studies hosted by the Digital Games Research section of ECREA. As the phenomena related to digital gaming keep on evolving and emerging, so must research keep up with the times and constantly challenge itself. Whether speaking about validating previously developed research methods, imagining totally new ones, or even challenging the whole philosophy of science on which research is being done, there is a constant need for reappraisal and introspection within games research. As a cultural medium that has become deeply embedded into the social fabr…
Recovering Sicilian Silk Heritage through Digital Technologies: The Case of Piraino’s Collection
2022
Textile conservation has given rise to small and medium-sized museums, usually with scarce resources. In Sicily, the little evidence that remains of silk production and opulent imports by the rich and powerful local aristocracy is kept in museums, parishes, and other cultural institutions. The documentation, dissemination, and enhancement of such a fragile heritage is today possible by means of technological tools that provide novel means to preserve, analyze, and exploit digital information. In this paper, we present some outcomes of the SILKNOW project, a project that applies computing research to the needs of diverse users (museums, educational institutions, the tourism industry, creativ…
Development of niobium-based superconducting junctions
2012
This thesis presents a review of publications which mainly focuses on the fabrication and performance of Nb-based normal metal-insulator-superconductor (NIS) tunnel junctions and superconductor-normal metal-superconductor (SNS) Josephson junctions at low temperatures. The Cu/AlOx-Al/Nb based NIS double tunnel junctions were successfully fabricated using conventional electron beam lithography combined with multi-angle thermal evaporation of metals in ultra high vacuum. The subgap characteristics of these junctions showed expected temperature dependence from 0.2 K to 5 K with a good thermometry sensitivity 0.2-0.3 mV/K. Signatures of small electronic cooling effects were observed near the Nb …
Retos en la internacionalización y supervivencia de los nuevos emprendimientos manufactureros
2015
El objetivo de este trabajo es analizar la relación entre la orientación internacional y la supervivencia de empresas manufactureras de reciente creación. Para ello se estudió una muestra de 2.975 nuevos emprendimientos constituidos durante el período 2001-2010 en la industria textil-confección de España. Metodológicamente, se han empleado modelos de duración mediante regresiones de Cox, que modelizan el riesgo relativo asociado con una variable en función del tiempo transcurrido hasta que sucede el evento. Los principales resultados evidencian que la internacionalización de los nuevos emprendimientos es una condición necesaria aunque no suficiente para sobrevivir en una industria globaliza…
Axiology of the historial city and the cap rate. The case of the old town of Ragusa Superiore
2017
Il contributo affronta il tema del ruolo che il mercato immobiliare assume nei processi di valorizzazione dei tessuti urbani storici nella logica dell’approccio al valor capitale. L’articolazione, eterogeneità e multi-contestualità del patrimonio immobiliare della città storica, la molteplicità delle relazioni tra valori e prezzo, la complessa dialettica fondo/flusso, l’eterogeneità dei profili dei soggetti economici che interagiscono nel mercato, danno vita ad un assortimento di approcci all’investimento immobiliare che in questo contributo, attraverso l’analisi del saggio di capitalizzazione si intendono rappresentare. La convergenza tra valori di contesto e potenzialità inespresse da una…
Wybrane przykłady realizacji koncepcji miasta-ogrodu oraz możliwości implementacji ich elementów we współczesnej tkance miejskiej
2020
Praca stanowi przekrój myśli urbanistycznej, jaką jest koncepcja miasta- ogrodu. Celem pracy jest przedstawienie sposobu kształtowania współczesnej tkanki miejskiej w odniesieniu do założeń garden city na przykładzie miasta Opole. Obecne tendencje w planowaniu przestrzennym miast zdają się nie uwzględniać szeroko rozumianego krajobrazu jako waloru. Niniejsza praca powstała z myślą o przybliżeniu założeń opartych na zasadzie połączenia środowiska zbudowanego z naturalnym, pokazując, że mogą być one funkcjonalnymi i kompletnymi tkankami miejskimi
