LIQUIDI IONICI E FULLERENI: PIATTAFORME PER NUOVI MATERIALI
The synthesis of innovative catalysts based on different carbon nanoforms (CNFs), namely fullerene C60 and carbon nanotubes (CNTs), and their application in Suzuki and Heck C-C coupling reactions, constitutes the common thread of the first part (Chapter 1 and 2) of this thesis. C60 and CNTs were functionalized with ionic liquids (ILs) and poly-amidoamine (PAMAM) dendrimers, respectively, and used as supports for palladium nanoparticles (PdNPs). Moreover, additional supported catalytic systems based on one of the synthesized C60-IL hybrids were prepared and successfully employed in the title coupling reactions. The final part (Chapter 3) of the thesis deals on the microwave-mediated synthesi…
Fullerene-containing Polymers
2012
In the present chapter, the different C60-based polymers have been classified according to structural parameters and the different synthetic strategies to prepare them have been highlighted. Two new families have been added, namely fullerene–nanotubes hybrid and DNA–fullerene hybrid, due to the nondiscrete nature of the corresponding members. Finally, fullerene-containing polymers’ most promising applications have been discussed, mainly focusing on nonlinear optics, DNA-cleaving and photovoltaic properties.
ASYMMETRIC SYNTHESIS OF LINEZOLID THROUGH CATALYZED HENRY REACTION
2013
Linezolid 1 is an antibacterial oxazolidinone approved by FDA in 2000 for the treatment of fastidious bacterial infections.1 The asymmetric synthesis of Linezolid-like molecules make use of the chiral pool approach, through the so-called Manninen reaction.2 This strategy requires the use of BuLi, low temperature and a long elaboration of the acetamide chain. Curiously, the only catalyzed approach toward the asymmetrical synthesis of Linezolid was just recently reported, and belongs to the use of proline-derived catalysts in aldol reactions as the key step.3 This procedure is quite interesting except for the low yield. Here we report a new synthesis of Linezolid, based on a Cu(II)-catalyzed …

Exergoeconomic analysis as a tool for supporting the design and operation of multiple chiller systems in air conditioning applications.
2019
Multiple-Chillers systems represent viable solutions for medium/large-scale air conditioning applications. In these systems, however, design and energy savings are highly affected by the configuration and operation strategies adopted. For instance, when considering multiple chillers of same size, “symmetric” or “sequential” load sharing strategies are two viable options. Conversely, when considering chillers of different sizes, a wide combination of chillers cooling capacities may be adopted. It is apparent that an integrated analysis of the design and operation of these systems should be carried out in order to achieve profitable energy saving. With this respect, Exergoeconomics, which res…
