Abstract:

La ténacité et l’énergie de surface de fracture de verres, de vitrocéramiques et de composites à matrice en verre ont été étudiées. Tout d'abord, un test de flexion bi-axiale (configuration anneau/anneau) a été réalisé sur des verres de silice et des verre-à-vitres avec différentes conditions de surface afin d’identifier la relation entre le défaut de surface, la résistance et la ténacité du verre. Ensuite, trois méthodes d’expérimentation ont été mises en œuvre, principalement la méthode de poutre de flexion à pré-entaille droit (SEPB), la méthode de la poutre entaillée en chevron (CNB) et la

Abstract:

In recent years, research has focused on reducing the cost of catalysts in a variety of ways including using less expensive materials, improving the synthetic method, and increasing the catalytic activity, recovery, and recyclability. Typically with nanoparticles, the size, shape, composition, and surface coating have an effect on catalytic activity.1-2 In this work, we focused on reducing the cost of precious metal based catalysts by altering the synthetic methods. One way to lower the cost of synthesizing precious metal nanoparticles is by debasing the precious metal with a second cheaper mo

Abstract:

In the last few years, the application of nanomaterials (NMs) as theranostic devices, which combine diagnostic and therapeutic features, has gained a tremendous interest and development. Still, the major challenge is the understanding of the many and often complex processes that occur during the interaction of biological compounds with nanomaterials, in order to modulate their responses to the fixed target. A fine development of such smart nanosystems could occur only by a critical control of chemical/physical properties of NMs at the biological interfaces. According to such premises, this t

Abstract:

Organic/inorganic interfaces play a key role in organic electronic devices such as organic light emitting diodes (OLED), organic field effect transistors (OFET) and organic solar cells (OSC). In these interfaces crucial processes such as charge injection or extraction take place. Improving the performance of these devices has the potential to result in more efficient sources of lighting, printable electronics, and highly scalable solar energy harvesting. With this aim, a solid understanding at atomic level of the structural and electronic properties of organic/inorganic interfaces is needed.

The advent of nanoscience and nanotechnology has sparked many research forefronts in the creation of materials with control over size, shape, composition, and surface properties.1,2 However, for most of the applications, nanoscale materials need to be assembled into functional nanostructures that exhibit useful and controllable physical properties. Therefore, numerous efforts on the assembly of nanoparticles (NPs) using organic ligands, polymers and polyelectrolytes have been reported.3,4 However, the interactions between NPs are mediated by intervening ligands, which are detrimental to charge

Abstract:

Gold nanoshells, a material generally composed of a core of silica surrounded by a thin shell of gold, are of great interest due to their unique and tunable optical properties. By varying the shell thickness and core size, the absorption and scattering properties are greatly enhanced. The nanoshells can be made to absorb or scatter light at various regions across the electromagnetic spectrum, from visible to the near infrared. The ability to tune the optical properties of nanoshells allows for their potential use in many different areas of research such as optical imaging, tumor ablation, drug

Single-walled metal oxide nanotubes have emerged as an important class of 'building block' materials for molecular recognition-based applications in catalysis, separations, sensing, and molecular encapsulation due to their vast range of potentially accessible compositions and structures, and their unique properties such as well-defined wall structure and porosity, tunable dimensions, and chemically modifiable interior and exterior surfaces. However, their widespread application will depend on the development of synthesis processes that can yield structurally and compositionally well-controlled

An innovative polymerisation technique was used to synthesise the novel polymer-based materials.

The formation of alloyed and non-alloyed BNPs is achieved through pulse laser ablation (PLA) and a significant increase in catalytic activity is observed for both.

Abstract:

Il monitoraggio della qualità dell’aria é un primo passo attraverso un futuro migliore perché ci segnala quale processo emette più sostanze dannose nell’atmosfera e dove c’è bisogno di applicare tecnologie nuove per ridurre le emissioni. In questo lavoro, la componente organica (IPA, TC-EC-OC, levoglucosano) e quella inorganica (metalli) sono state determinate mediante il monitoraggio attivo (filtri) e il biomonitoraggio (T. aeranthos).<br>In this study, the organic and inorganic fraction of the airborne particulate matter was determined on a) filter devices (active sampling), and b) by biomon

2013 - 2014<br>In this PhD work, a series of eight new group 4 metal complexes 1−8 (1 = (t- BuOS)2TiCl2; 2 = (CumOS)2TiCl2; 3 = (t-BuOS)2Zr(CH2Ph)2; 4 = (CumOS)2Zr(CH2Ph)2); 5 = (t-BuOS)2Ti(OiPr)2; 6 = (t-BuOS)2Zr(OtBu)2; 7 = (t- BuOS)2Hf(OtBu)2; 8 = (CumOS)2Zr(OtBu)2) supported by two phenolate bidentate ligands (t-BuOS−H = 4,6-di-tertbutyl- 2-phenylsulfanylphenol and CumOS−H = 4,6-dicumyl-2- phenylsulfanylphenol) were synthesized by the reaction of appropriate metal precursors with 2 equiv of the ligands. These complexes were characterized by means of 1H- and 13C-NMR spectroscopy and the com

Abstract:

The sediment quality of Venice lagoon was assessed through collection and analysis of sediment samples in 380 sites in the shallow water areas. Heavy metal (Al, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, ZN) and As contents were measured in fillet, liver, stomachs and otoliths of 280 specimens collected in five areas of the Lagoon (Laguna Nord, Ponte della Libertà, Lago dei Teneri, Poveglia and Santa Maria del Mare). The concentration of metals in most specimens does not reflect the total concentration in sediment. Cd, Hg and Pb values measured in the edible part of the fish are lower than the levels req

Abstract:

Chemisorption–hydrolysis (CH) represents a fruitful preparation method, as it combines the simplicity of impregnation techniques, both in terms of handiness and cheapness, with the high metal dispersion obtained by anchoring techniques. In this work different Cu, Co and Co-Cu catalysts were prepared by CH. The characterization of CH copper silica materials agree on the formation of finely dispersed phase of CuO, easily reducible to metal copper at any copper loading. In particular CH method allows to keep a great dispersion obtaining very small copper particles also to an higher metal loadin
