Book Description
L'oxydation est le mode le plus général de vieillissement des polymères. Peu de domaines d'application de ces matériaux échappent à des préoccupations de durabilité liées au vieillissement oxydant. Les concepteurs et utilisateurs de ces matériaux ont besoin d'outils fiables pour la prédiction de durée de vie. Seule une approche non empirique peut garantir une telle fiabilité. Elle implique une série d'étapes relevant de disciplines différentes comme la chimie organique radicalaire, la physico-chimie macromoléculaire, la physique des processus de transport et la physique des polymères. Le présent ouvrage consacre un chapitre à chacune des étapes de cette démarche en mettant l'accent sur les aspects cinétiques présentés de manière originale. Une attention particulière est portée aux liens entre les différentes disciplines qui, jusqu'ici, avaient tendance à s'ignorer. Les chercheurs et ingénieurs concernés par le problème trouveront dans cet ouvrage des éléments pour accomplir la totalité de la démarche de prédiction de durée de vie, du mécanisme réactionnel à l'évolution des propriétés mécaniques.

Book Description
Covering every essential element in the development of chiral products, this reference provides a solid overview of the formulation, biopharmaceutical characteristics, and regulatory issues impacting the production of these pharmaceuticals. It supports researchers as they evaluate the pharmacodynamic, pharmacokinetic, and toxicological characteristics of specific enantiomers and chiral drug compounds and addresses in one convenient reference all the major challenges pertaining to drug chirality that have been neglected in the literature. Chirality in Drug Design and Development collects the latest studies from an interdisciplinary team of experts on chiral drug design.

Book Description
This book explains theoretical and technological aspects of amorphous drug formulations. It is intended for all those wishing to increase their knowledge in the field of amorphous pharmaceuticals. Conversion of crystalline material into the amorphous state, as described in this book, is a way to overcome limited water solubility of drug formulations, in this way enhancing the chemical activity and bioavailability inside the body. Written by experts from various fields and backgrounds, the book introduces to fundamental physical aspects (explaining differences between the ordered and the disordered solid states, the enhancement of solubility resulting from drugs amorphization, physical instability and how it can be overcome) as well as preparation and formulation procedures to produce and stabilize amorphous pharmaceuticals. Readers will thus gain a well-funded understanding and find a multi-faceted discussion of the properties and advantages of amorphous drugs and of the challenges in producing and stabilizing them. The book is an ideal source of information for researchers and students as well as professionals engaged in research and development of amorphous pharmaceutical products.

Book Description
The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.
