This paper describes the probabilistic assessment of seismic hazard (PSHA) Italy in view building codes from 2003 to 2009. A code was issued as a Prime Minister Ordinance, requiring that PSHA for updating zoning would be performed one year, terms horizontal peak ground acceleration (PGA) with 10% probability exceedance 50 years on hard ground. For first time Italy, working group, established by Istituto Nazionale di Geofisica e Vulcanologia, adopted logic-tree approach model epistemic...
In the frame of European Commission project "Seismic Hazard Harmonization in Europe" (SHARE), aiming at harmonizing seismic hazard a scale, compilation homogeneous, parametric earthquake catalogue was planned. The goal to be achieved by considering most updated historical dataset and assessing homogenous magnitudes, with support from several institutions. This paper describes SHARE Earthquake Catalogue (SHEEC), which covers time window 1000–1899. It strongly relies on experience "Network...
Abstract Biomass constitutes a renewable source for new chemical platforms. Among other processes the catalytic ones represent green alternative when active and selective catalysts can be developed. In this paper, applications of gold gold‐based have been reviewed in field oxidations. Indeed, from discovery peculiarity as material, liquid phase oxidations differently viewed. Three important biomass‐derived molecules, namely glucose, hydroxymethyl furfural (HMF) glycerol considered precursors...
Oxidation of 5-hydroxymethylfurfural (HMF), a major feedstock derived from waste/fresh biomass, into 2,5-furandicarboxylic acid (FDCA) is an important transformation for the production biodegradable plastics. Herein, we investigated effect support (unmodified and modified titania, commercial alumina, untreated treated Sibunit carbon) mono- bimetallic catalysts based on noble metals (Ag, Au, Pd) selective HMF oxidation with molecular oxygen to FDCA under mild basic reaction conditions. The...
In this work we show the possibility of using pigmentary TiO<sub>2</sub>-powders as photocatalysts and develop a kinetic model which is able to follow behavior nano-TiO<sub>2</sub><italic>versus</italic> micro-TiO<sub>2</sub> in ethanol degradation.
Pharma-products are mostly single or multiple cyclic compounds. They pollute surface water and persistent in the aquatic ecosystem. When irradiated by UV light, TiO2 catalysts cleave degrade organic contaminants water. Removal of organics photocatalysis results from a synergistic effect adsorption photocatalysis. Synthesis ultrasound (US) produces high area porous solids. Here, we synthesized Mn-doped with US-assisted sol-gel method. Compared to classical synthesis, US increased BET 83 m2...
The most important drawback of the use TiO2 as photocatalyst is its lack activity under visible light. To overcome this problem, surface modification commercial micro-sized by means high-energy ultrasound (US), employing CuCl2 precursor molecule to obtain both metallic copper well oxides species at surface, here. We have prepared samples with different content, in order evaluate impact on photocatalytic performances semiconductor, and studied particular photodegradation gas phase some...
Sonochemistry is based on acoustic cavitation, which consist in the formation, growth, and implosive collapse of bubbles within a liquid. Collapsing generate localized hot spots, characterized by temperatures up to 5000 K pressures 1800 atm. These extreme conditions allow producing variety nanostructured amorphous materials, as well they are advantageous for chemical processes. Ultrasound requires inexpensive equipment fewer steps than conventional methods. Combining ultrasound...
The probabilistic seismic hazard of Italy was assessed in 2004 to match the requirements new provisions. This such map, now recognized as official reference for design according building and administrative issues, is result a comprehensive model that takes into account variability seismicity, seismogenic potential, propagation different areas Italy. Since 2004, we have computed terms peak ground acceleration spectral values varied annual probabilities exceedance, including measure their...
Three independent techniques (Bakun and Wentworth, 1997; Boxer from Gasperini et al. , 1999; Macroseismic Estimation of Earthquake Parameters [MEEP; see [Data Resources][1] section, deliverable D3] R.M.W. Musson M.J. Jimenez) have been proposed for estimating an earthquake location magnitude intensity data alone. The locations magnitudes obtained a given set are almost always different, no one technique is consistently best at matching instrumental recent well-recorded earthquakes in Italy....
TiO2-based photocatalysis under visible light is an attractive way to abate air pollutants. Moreover, developing photocatalytic materials on a large-scale requires safe and low-cost precursors. Both high-performance TiO2 nanopowders visible-light active noble metals do not match these requirements. Here, we report the design of novel Mn-decorated micrometric particles. Pigmentary replaced unsafe nano-TiO2 firmly supported MnOx Mn such as Au or Ag, opening for development lower cost...
Gold nanoparticles supported on various oxides (CeO2, CeO2/TiO2, MgO, MgO/TiO2, La2O3, La2O3/TiO2) (with 4 wt.% Au loading) were investigated in the liquid (aqueous) phase oxidation of glycerol by molecular oxygen under mild conditions, presence alkaline earth (CaO, SrO and MgO) or (NaOH) bases. Full conversion selectivity between 38 68% to sodium glycerate observed different catalysts (Au/MgO/TiO2, Au/La2O3/TiO2, Au/CeO2 Au/CeO2/TiO2). The combined effect particle size basicity support was...
