Abstract

In biotechnology the current downstream processing trends are directed towards integrated, faster and more effective processes. Electrofiltration is a hybrid method which is a combination of membrane filtration and electrophoresis in a dead-end process. Spatially distributed process analysis together with the applicability of electrofiltration for technically important biopolymers such as PHB, chitosan and hyaluronic acid enables the implementation of the technology into industry.

Abstract

Micro-extraction techniques in sample preparation are gaining interest among analytical chemists as they comply with green analytical chemistry demands and ensure environmental protection and public safety. Savings in cost and time are considered as valuable benefits by using novel micro-extraction approaches in sample handling. Selectivity, sensitivity and lower detection limits are also included among the performance characteristics required to meet the legislation criteria.The target of this special issue is to present the state of art in microextraction sample preparation techniques. Modern, simple and efficient methods for preconcentration and separation are described for different analytes isolated from various matrices.

Abstract

La loi du 9 décembre 1905 sur la Séparation des Églises et de l'État est consacrée aujourd'hui comme une pièce essentielle du socle républicain. Ce n'était pas le cas à la veille de son adoption. Dès lors, c'est dans la pratique de la loi par les pouvoirs publics qu'il faut rechercher les origines de l'adhésion progressive de la société française aux principes affirmés par le texte. En publiant les communications de chercheurs et les interventions d'acteurs politiques et de responsables des grandes institutions religieuses que le colloque tenu les 9 et 10 décembre 2005, cet ouvrage permet de mesurer l'ampleur et la diversité d'une évolution séculaire de la société française tout en identifiant les étapes et l'originalité de la laïcisation française et en évaluant les limites.

Abstract

Fluid transport in narrow pores is central to the design and optimization of nanoporous materials in industrial applications, such as catalysis, nanofluids, electrochemical batteries, and membrane separation. However, due to the strong potential field in nanopores, conventional models and methods have become inadequate for predicting the transport behavior of molecules confined in the pore space. In addition, the inherent complexity of the pore structure in nanomaterials requires consideration of local or nanoscale transport at the single pore level, and averaging over the macroscale, which further impedes the application and validation of the formulated mechanical models. To solve the problem of fluid transport in narrow nanopores beyond Knudsen limits, experimental characterizations should be combined to molecular simulations in order to probe the fluid movement under realistic conditions. This book provides comprehensive perspectives on the current research in the investigation of fluid transport processes in nanomaterials. The articles from leading scholars in this field are conveniently arranged according to three categories based on the approaches used in the papers: modeling and simulation, nanomaterial manipulation and characterization, and practical application. The 14 contributions not only demonstrate the importance of fluid behavior in different applications but also address the main theories and simulations to model the fluid transport behavior in nanoporous materials. This collection shows that “fluid transport in nanomaterials” remains a versatile and vibrant topic in terms of both theories and applications.

Abstract

La laïcité française, loin d’avoir été un simple aménagement technique des rapports entre l’Église et l’État, a longtemps figuré au nombre des principes fondamentaux de la société française : elle visait à asseoir l’ordre politique sur les prescriptions de la raison universelle, à reléguer les appartenances confessionnelles dans la sphère privée et à instituer l’État en conscience rectrice de la communauté des citoyens. Or, depuis quelques années, ce modèle est sévèrement questionné. À la « s...

Abstract

Lone parenthood is an increasing reality in the 21st century, reinforced by the diffusion of divorce and separation. This volume provides a comprehensive portrait of lone parenthood at the beginning of the XXI century from a life course perspective. The contributions included in this volume examine the dynamics of lone parenthood in the life course and explore the trajectories of lone parents in terms of income, poverty, labour, market behaviour, wellbeing, and health. Throughout, comparative analyses of data from countries as France, the United Kingdom, Ireland, Germany, Belgium, Sweden, Switzerland, Hungary, and Australia help portray how lone parenthood varies between regions, cultures, generations, and institutional settings. The findings show that one-parent households are inhabited by a rather heterogeneous world of mothers and fathers facing different challenges.Readers will not only discover the demographics and diversity of lone parents, but also the variety of social representations and discourses about the changing phenomenon of lone parenthood. The book provides a mixture of qualitative and quantitative studies on lone parenthood. Using large scale and longitudinal panel and register data, the reader will gain insight in complex processes across time. More qualitative case studies on the other hand discuss the definition of lone parenthood, the public debate around it, and the social and subjective representations of lone parents themselves. This book aims at sociologists, demographers, psychologists, political scientists, family therapists, and policy makers who want to gain new insights into one of the most striking changes in family forms over the last 50 years.

Abstract

In this work, the deposition of ZIF-8 surface-anchored metal-organic framework (SURMOF) films was systematically studied. A proper characterization and optimization of the synthesized films was performed and their separation performance was determined. Furthermore, a general description of the system was achieved using the Maxwell-Stefan surface diffusion model.

Abstract

Ba$_{0,5}$Sr$_{0,5}$Co$_{0,8}$Fe$_{0,2}$O$_{3-?}$ (BSCF) is the most promising material für energy efficient oxygen separation membranes. But its electrical and transport properties are unstable at temperatures below 840 °C. Reasons are structural changes to secondary phases in the cubic lattice. By doping with Y, Ti and Nb the cubic lattice shall be stabilized. Goal of this work are analyses of the dopant’s influences on BSCF’s electrochemical properties.
