Nuevas tecnologías y el Derecho a la Comunicación

El desarrollo experimentado en las últimas dos décadas de la tecnología ha producido un cambio trascendente en la comunicación y es motora del proceso de globalización y mundialización cambiando profundamente los modos de vida. Se crea la sensación de unificación de una multiplicidad de culturas y prácticas sociales, donde las diferencias y particularidades son borradas. Se plantea la visión de un mundo sin fronteras producto de las nuevas tecnologías y también junto a la comunicación aparece la responsabilidad jurídica; responsabilidad jurídica que se diluye en el anonimato producto de un mundo donde las fronteras se borran y los rostros se difuminan, cometiéndose infracciones internacionales como pornografía infantil, estafas, violación de propiedad intelectual de autores anónimos escondidos en la web.Fil: Juárez Centeno, Carlos A.

Synthesis and Visible-Light Photocatalytic Property of Bi2WO6Hierarchical Octahedron-Like Structures

A novel octahedron-like hierarchical structure of Bi2WO6has been fabricated by a facile hydrothermal method in high quantity. XRD, SEM, TEM, and HRTEM were used to characterize the product. The results indicated that this kind of Bi2WO6crystals had an average size of ~4 μm, constructed by quasi-square single-crystal nanosheets assembled in a special fashion. The formation of octahedron-like hierarchical structure of Bi2WO6depended crucially on the pH value of the precursor suspensions. The photocatalytic activity of the hierarchical Bi2WO6structures toward RhB degradation under visible light was investigated, and it was found to be significantly better than that of the sample fabricated by SSR. The better photocatalytic property should be strongly associated with the high specific surface area and the abundant pore structure of the hierarchical octahedron-like Bi2WO6

Particle suspension reactors and materials for solar-driven water splitting

Reactors based on particle suspensions for the capture, conversion, storage, and use of solar energy as H_2 are projected to be cost-competitive with fossil fuels. In light of this, this review paper summarizes state-of-the-art particle light absorbers and cocatalysts as suspensions (photocatalysts) that demonstrate visible-light-driven water splitting on the laboratory scale. Also presented are reactor descriptions, theoretical considerations particular to particle suspension reactors, and efficiency and performance characterization metrics. Opportunities for targeted research, analysis, and development of reactor designs are highlighted

Energy Efficiency in Industry 4.0: Assessing the Potential of Industry 4.0 to Achieve 2030 Decarbonisation Targets

The energy transition for the industrial sector is not limited to a reduction in energy consumption: the real issue is to combine sustainability with growth, by mixing the two ingredients (the rational energy use and the industrial growth) which are not always compatible. The National Energy and Climate Plan (NECP) and the New Green Deal policies in Italy have the goal to promote an economic development as well as the environment sustainability and social inclusion. RSE1 has investigated the role of the national incentive plan ‘Impresa 4.0’ in Italy (currently ‘Transizione 4.0’, equivalent to ‘Industry 4.0’) as a measure to promote the energy transition, analysing whether and how is it possible to combine economic development with energy efficiency. Originally, it was developed to increase the competitiveness of industrial sector, but, progressively, it was also used to promote energy efficiency and sustainability. A survey was carried out by RSE on about 300 companies that implemented innovation and digitalisation interventions, monitoring the effects and impacts that the ‘4.0 choice’ has determined on energy consumption, on their environmental externalities and, in general, on other costs. Moreover, some case studies were collected, together with a database of ‘Impresa 4.0’ application, which supported technical and economic evaluations. The impact of these measures on energy performance of the companies was estimated from the analysis of actual projects and from interviews and discussions with the operators. In this paper, the results of the survey are presented and the outcomes are analysed in comparison with the Italian manufacturing sector performance, in order to establish the potential of ‘Impresa 4.0’ policies in supporting the decarbonisation process and reaching 2030 environmental targets.This work was financed by the Research Fund for the Italian Electrical System in compliance with the Decree of Minister of Economic Development on 16 April 2018
