“…Strictement parlant, il existe une association claire entre l'énergie d'interaction minimale et la minimisation du taux de changement d'entropie par la sélection du chemin de solidication ordonné représenté dans l'espace des phases. Comme le remarquait bien Nishinaga, il y a un art et une science de la croissance du cristal [62], étant fondamentale pour la maîtrise des deux la connaissance de la thermodynamique. Les approches pédagogiquement plus productives commencent à partir de la soi-disant nucléation entre les corpuscules de vapeur d'eau, formant des gouttes de pluie.…”

RésuméCette thèse traite de la mise en ouvre d'un nouveau mode de gestion des déchets urbains en termes de la destination non-agressif et productif des débris, à de faibles coûts énergé-tiques et à forte réutilisation des sous-produits. Il repose sur les fondements scientiques établies par la thermodynamique, la théorie classique du champ et par les disciplines empiriques qui traitent de propriétés des éléments chimiques et des technologies de capture calorique à partir de sources éloignées. Visant à la transformation de toute forme de matière condensée, ce travail est principalement intéressés par les déchets dits infectieux, parce qu'ils ont dune plus grande virulence, l'infectiosité et concentration, et les déchets de type peau-ciseaux-perçage, qui sont des objets et instruments contenant des coins, des arêtes ou des protubérances rigides et aiguës capables de coupe ou de forage. Néanmoins, le modèle s'applique également à tous les types de déchets, à l'exception des déchets radioactifs pour des raisons évidentes de sécurité. Cet essai propose un système industriel de recyclage des déchets basé sur la pyrolyse induite par plasma et guidé par la théorie proposée des champs caloriques sous entropie contrôlée.Mots-clés: déchets nosocomiales, thermodynamique, champ calorique, plasma, pyrolyse, énergie solaire, durabilité i Abstract This thesis discusses the implementation of a new way of urban waste management in terms of its non-aggressive and productive destination, at low energy costs and with high reuse of byproducts. It is based on scientic foundations established by thermodynamics, classical eld theory and empirical disciplines that deal with properties of chemical elements and with technologies of caloric capture from remote sources.Aiming at the transformation of any form of condensed matter, it is primarily interested in the so-called infectious waste, because they have greater virulence, infectivity and concentration, and wastes of type skin-scissoring-piercing, which are objects and instruments containing corners, edges or rigid and acute protuberances capable of cutting or drilling. Nevertheless, the model also applies to all types of waste, with the exception of radioactive waste for obvious safety reasons. Present work proposes an industrial system to recycling waste based on pyrolysis induced by plasma and guided by the proposed theory of caloric elds under controlled entropy.

“…Solution crystallization, as one of the most important separation and purification methods, is widely used in pharmaceutical, food, energy, and many other fields. The design and operation of crystallization processes have important impacts on the physicochemical properties of the final products, such as purity, bulk density, and polymorphs. − The crystal growth is of great concern in solution crystallization, since the crystal growth not only determines the crystal size and its distribution, but also influences the final morphology, and thus impacting the subsequent downstream processing (e.g., filtration and drying) and applications (e.g., flowability, tablet, and bioavailability). − Clearly, understanding crystal growth is of utmost significance for product quality control in industrial crystallization.…”

Crystal growth, which is one of the fundamental steps in the crystallization process, can affect the morphology of crystals which will further affect physicochemical properties of products and downstream processing. In this study, crystal growth of cefradine in aqueous solution was systematically investigated by combining experimental methods and molecular dynamics simulations. Single crystal growth experiments were adopted to obtain the growth kinetics data of cefradine in water. Growth kinetics models considering the bulk diffusion step and surface integration step were applied to evaluate the experimental data. Surface chemistry, Connolly surface, radial distribution function, and electrostatic potential were calculated through molecular dynamics simulation to further explore the growth kinetics from the molecular level. The results revealed that water molecules preferred to be adsorbed onto the (1 0 1) crystal face than the (0 1 1) and (0 1̅ 1) surfaces due to the favored hydrophilicity and solvent adsorption sites. In addition, the stronger interaction between water molecules and the (1 0 1) crystal face by electrostatic and hydrogen-bonding interactions would further highly hinder the crystal growth along the radial direction. Finally, a possible growth mechanism based on blocking effect of solvent molecules was proposed to interpret the different growth kinetics along the axial and radial directions.
