Opis:
The most careful and consolidated risk analysis methods, as FTA, ETA, FMEA/FMECA, focus attention on system reliability. But, looking at OHS, a deep analysis on European data on accidents at work and on work environment in general, shows how reliability is only one aspect of safety problem. These methods then are hardly adaptable when the main aim is to obtain a quantitative assessment of risk for workers; besides, Rother methodologies are nearest to OHS but give only qualitative results like HAZOP, or base their analysis on notdimensional values, fixed by analyst on personal experiences, like methods proposed by UNI EN 1050, by standard MIL-STD-882c and by AISS. RATE is proposed as a new quantitative methodology for OHS, particularly dedicated to SMEs considered as the most interesting from these aspect. The paper compares hypothesis and procedures which traditional quantitative methodologies and RATE are based on, to give evidence at the main approach aspects that have to be modified in order to move from reliability to OHS.

Opis:
Traditional risk assessment methodologies have been thought for large enterprises and they are not easy to handle by small and medium enterprises (SMEs): that can hardly assign resources to safety analysis. However, occupational health and safety is even more important in SMEs since their core competencies are based on skilled manpower. Attempting to solve this problem, a new methodological approach was developed: RATE (Risk Analysis by Threshold Evaluation) is a “bottom up” method which allows safety analysts to follow a standard path, not much time-spending due to a semi-probabilistic approach and enabling identification of hidden risks. RATE perspective is centred on recognising risks for workers rather than machine ways of failure. It is aimed to help entrepreneurs to assess the capacity of their system to reach a desired safety level and to what extent safety measures can improve safety performance.

Opis:
In the present work, the fabrication and characterization of non-curling, free-standing $TiO_2$ nanotube membranes and their integration in front-side illuminated dye-sensitized solar cells are reported. Vertically oriented $TiO_2$ nanotube arrays were fabricated by anodic oxidation of a titanium foil. Nanotube membranes were detached from the metallic foil, transferred and bonded on transparent fluorine-doped tin oxide/glass substrates employing a $TiO_2$ sol as a binder. Crystalline phase and morphology of the film were investigated, evidencing the formation of a highly ordered 1D nanotubes carpet, with a pure anatase crystalline structure. $TiO_2$ nanotube-based DSCs were fabricated using reversible microfluidic architecture. The cell performances were studied by I-V electrical characterization, incident-photon-to-electron conversion efficiency, electrochemical impedance spectroscopy and open circuit voltage decay measurements, showing an increase in electron lifetime compared to nanoparticle-based dye-sensitized solar cells.

Opis:
We propose a 3D branched ZnO nanostructure for the fabrication of highly efficient dye-sensitized solar cell photoanodes. A coral-shaped structured Zn layer was deposited by radio frequency magnetron sputtering at room temperature onto fluorine-doped tin oxide/glass sheets and then thermally oxidized in ambient atmosphere, obtaining a high-density branched ZnO film. The porous structure provides a large surface area, and, as a consequence, a high number of adsorption sites, and the size and spacing of the nanostructures (on the order of the exciton diffusion length) are optimal for good electron collection efficiency. The proposed synthesis technique is simple and scalable and the reproducibility of the growth results was tested. The crystalline phase of the film was investigated, evidencing the complete oxidation and the formation of a pure wurtzite crystalline structure. ZnO-based solar harvesters were fabricated in a microfluidic architecture, using conventional sensitizer and electrolyte. The dependence of the cell efficiency on dye incubation time and film thickness was studied with I-V electrical characterization and electrochemical impedance spectroscopy. The obtained conversion efficiency values, with a maximum value of 4.83%, confirm the highly promising properties of this material for the implementation in dye-sensitized solar cell photoanodes.
