L’objectif de ce travail était d’évaluer les outils de contrôle qualité utilisés au CHU de Liège, pour le site de Sainte Rosalie en ce qui concerne les faisceaux FFF d’énergie 10MV et de son application en routine clinique. Pour cela nous avons utilisé le protocole NCS33 qui est une prépublication. Le profil de dose d’un faisceau plat pour la taille du champ à irradier est définie par la longueur reliant l’isodose 50%, ce qui n’est plus vrai pour un faisceau FFF. L’isodose 50% n’étant pas forcément dans la pénombre. Le protocole NCS33 propose d’ajuster un modèle pour déterminer les points d’inflexion des courbes et par-delà les tailles de champ. Un nouveau paramètre est introduit qui est le top position provenant lui aussi de l’ajustement d’un modèle sur la partie centrale du faisceau FFF. Cependant ce nouveau paramètre ne peut être utilisé que pour des tailles de champs supérieurs à 15x15 cm. Le protocole de contrôle des faisceaux FFF défini dans le programme MyQAAccept de la cuve à eau a été comparé à celui du NCS33 et nous avons obtenu des résultats similaires. Une étude dosimétrique du faisceau d’énergie 10 MV FFF réalisé sur des 20 cas cliniques a été effectué. Il ressort de cette étude que, le faisceau d’énergie 10 MV FFF ne permet pas d’obtenir des plans de traitements cliniquement acceptables lorsque nous sommes en fractionnement normal (1.8 et 2Gy). Pour des traitements hypofractionnés (2.5 à 9Gy), nous avons de meilleurs plans de traitements cliniquement acceptables que ceux planifiés avec les faisceaux d’énergie 6MV WFF surtout qui peuvent être délivrés plus rapidement (moins de 11s à 60s que les faisceaux normaux de 6MV WFF) et avec moins de segment. Cependant on constate une augmentation du nombre d’unités moniteur de plus de 51% et de la métrique.

This book introduces the reader to thermal field-flow fractionation and discusses its advantages over the fundamental problems associated with traditional column-based analytical techniques commonly used to characterize polymers and macromolecules. The authors discuss the theoretical background, equipment, experimental procedures as well as the recent advances and applications of thermal field-flow fractionation. Complete with several practical examples and troubleshooting guidelines, the book is written for beginners and experienced separation scientists alike and will enable its readers to optimize their experimental conditions for their specific separation needs and problems.

This is a timely collection of important biomedical applications for a set of separation/characterization techniques that are rapidly gaining popularity due to their wide dynamic range, high resolution, and ability to function in most commonly used solvent systems. Importantly, the field-flow fractionation (FFF) technique has recently emerged as a prominent complement to size exclusion chromatography for protein pharmaceuticals. Fractionation with FFF is gentle and preserves protein structural integrity better than existing alternatives. In the present text, different chapters are written by experts in their respective field of application, who offer comparisons between the FFF techniques and other methods for characterizing their special focus material. Practical guide-lines for successful implementation, such as choice of operating conditions, are offered in conjunction with each application. In addition to new instrumentation and approaches that address important current topics, readers are provided with an overall sense of prior (but timeless) major developments that may be overlooked in literature searches. .

Materials processing is the first, and a key, step in proper utilization of the composition of a given material and to realize the microstructural features that are intended to attain desired property levels for a given application. Both primary and secondary processing methods are equally important in tailoring the end properties of materials. In view of the crucial importance of the processing of materials, this Special Issue is intending to cover all innovative aspects of primary processing (solid phase, liquid phase, two phase, 3D printing, rapid solidification, etc.) and secondary processing (such as variations in extrusion, forging, rolling, equichannel angular extrusion, etc.) of materials (polymers/metal/ceramic-based, including their composites). Desirable attributes expected for submission will be processing–microstructure–property interrelations.

“Functional Polymer Solutions and Gels—Physics and Novel Applications” contains a broad range of articles in this vast field of polymer and soft matter science. It shows insight into the field by highlighting how sticky (non-covalent) chemical bonds can assemble a seemingly water-like liquid into a gel, how ionic liquids influence the gelation behavior of poly(N-Isopropylacrylamide) as well as how the molecular composition of functional copolymers is reflected in the temperature-responsiveness. These physics were augmented by theoretical works on drag-reduction. Also, drug-release – an improved control of how fast or dependent on an external factor – and antibacterial properties were the topic of several works. Biomedical applications on how cell growth can be influenced and how vessels in biological systems, e.g., blood vessels, can be improved by functional polymers were complemented with papers on tomography by using gels. On totally different lines, also the topic of how asphalt can be improved and how functional polymers can be used for the enrichment and removal of substances. These different papers are a good representation of the whole area of functional polymers.
