L'objet de cette thèse est de déterminer quels sont les droits et devoirs des chercheurs. Plus précisément, il s'agit d'examiner comment la norme se saisit des chercheurs dans leur diversité tant dans le processus de recherche - c'est-à-dire pendant la phase du choix des sujets de recherche et celle de la conduite des investigations - qu'après l'obtention d'un résultat scientifique. Il en résulte que, durant le processus de recherche, les chercheurs doivent bénéficier d'une liberté hors du commun afin que puissent librement s'exprimer leurs qualités inventives. Néanmoins, en tant qu'activité humaine oeuvrant pour le bien commun et puissant moteur des économies modernes, la recherche doit être orientée et encadrée par les pouvoirs publics. Une fois le résultat scientifique obtenu, un arbitrage entre différents impératifs opposés - ceux de l'économie et ceux de la recherche - doit être réalisé. Le droit doit, à la fois, inciter à la recherche et à l'innovation, permettre une large et rapide diffusion des résultats ainsi que leur valorisation économique pour que la recherche puisse continuer à progresser. Les droits et devoirs des chercheurs ont, à ce |

Sommario/riassunto |
|
Biomass has received significant attention as a sustainable feedstock that can replace diminishing fossil fuels in the production of value-added chemicals and energy. Many new catalytic technologies have been developed for the conversion of biomass feedstocks into valuable biofuels and bioproducts. However, many of these still suffer from several disadvantages, such as weak catalytic performance, harsh reaction conditions, a high processing cost, and questionable sustainability, which limit their further applicability/development in the immediate future. In this context, the esterification of carboxylic acids represents a very valuable solution to these problems, requiring mild reaction conditions and being advantageously integrable with many existing processes of biomass conversion. An emblematic example is the acid-catalyzed hydrothermal route for levulinic acid production, already upgraded to that of higher value alkyl levulinates, obtained by esterification or directly by biomass alcoholysis. Many other chemical processes benefit from esterification, such as the synthesis of biodiesel, which includes monoalkyl esters of long-chain fatty acids prepared from renewable vegetable oils and animal fats, or that of cellulose esters, mainly acetates, for textile uses. Even pyrolysis bio-oil should be stabilized by esterification to neutralize the acidity of carboxylic acids and moderate the reactivity of other typical biomass- |

derived compounds, such as sugars, furans, aldehydes, and phenolics. This Special Issue reports on the recent main advances in the homogeneous/heterogeneous catalytic conversion of model/real biomass components into ester derivatives that are extremely attractive for both the academic and industrial fields.
