Taschenbuch. Zustand: Neu. Neuware -Die vorliegende Dissertation beschäftigt sich mit den experimentellen und analytischenUntersuchungen an der Kathode einer auf Polybenzimidazol (PBI) und Phosphorsäure basierten Hochtemperatur-Polymer-Elektrolyt-Membran-Brennstoffzelle (HT-PEM-BZ). Die Charakterisierung der Reaktionszonen an der Elektroden-Elektrolyt-Grenzfläche der Kathode wurde mittels chronoamperometrischer Messungen vorgenommen. Der transiente Zellstromverlauf bei einer Veränderung der Zellspannung wurde anhand von Cottrellschen Gleichungen aufgezeichnet und analysiert. Die Cottrellschen Darstellungen zweier modifizierter Kathoden zeigen eine Trennung der Zweiphasen- und Dreiphasenreaktionszone. Cottrellsches Verhalten einer durchschnittlichen, kommerziellen Kathode kann als eine Kombination der modifizierten Kathoden aufgefasst werden. Weitere Analysen zeigen die Möglichkeit auf, die für die Reaktion verfügbare Katalysatoroberfläche zu quantifizieren, und dass sich ein dünner Elektrolytfilm auf den Katalysatoroberflächen bildet. Die Entdeckung des Auftretens einer Zellstromhysterese durch Temperaturänderung wird vorgestellt. Der Zellstromverlust nach einem Temperaturzyklus wird durch eine Zellspannungserhöhung auf Leerlaufspannung wiederhergestellt. Frühere Untersuchungen zeigen, dass möglicherweise der Transport des erzeugten Wassers für den temporären Zellstromverlust verantwortlich ist. Die Erholung des Zellstroms verläuft proportional zu dem Betrag des Zellspannungsanstiegs. Auf der Basis der anfänglichen Untersuchungen und einer intensiven Literaturrecherche wird eine Hypothese zu dem beobachteten Phänomen aufgestellt. Der Effekt wird den Wechselwirkungen der auf der Platinkatalysatoroberfläche adsorbierten Spezies zugeschrieben. Ein auf dem Monte-Carlo-Verfahren basierendes Modell wurde dazu verwendet, die Temperaturabhängigkeit der adsorbierten Phosphorsäure zu beschreiben. Das Modell wird auf Grundlage des Alterungsprozesses des Katalysators, der zu einem Platinpartikelwachstum führt, validiert. Die Ergebnisse der Simulation stimmen qualitativ mit den experimentellen Messungen überein und können daher teilweise den in der Hypothese beschriebenen Mechanismus des Zellstromverlustes beweisen. 94 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This study is concerned with the beneficiation and characterization of Ethiopian kaolin for ceramic membrane fabrication. As compared to polymeric microporous membranes, ceramic microporous membranes can resist severe environments due to their high thermal stability, high chemical stability, excellent mechanical strength, biocompatibility, long lifetime, energy efficiency, availability, and sustainability. These outstanding properties made inorganic microporous membranes a primary candidate to be used for water purification and desalination applications.The use of low-cost ceramic membranes and the ease of construction at a small scale, make membrane-based separation technology attractive for grid-independent desalination where low-cost heat sources (low-grade waste heat, geothermal energy, and solar energy) are readily available. Recently, the major research in membrane technology is developing high-performance ceramic membranes from local inexpensive raw materials such as kaolin, ball clay, bentonite clay, quartz, bauxite, and others.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Hardly a decade ago, membrane receptors were an attractive but largely unproven concept. Since that time enormous progress has been made, and we are now able to consider receptors much more concretely. Their existence has been established, their binding properties have been determined, and in some cases, they have been highly purified and their physical-chemical properties studied. It is now even possible to visualize microscopically some receptors. This progress has resulted largely from the development of highly powerful methods. These methods are the subject of this volume. Although considerably diverse, different receptors share certain common pro perties, and common problems are encountered in their study. Consequently, a small number of techniques are particularly useful in studying different types of receptors. Thus, it makes sense to speak about membrane receptor methodology. A very apparent problem in the study of membrane receptors is their presence in exceedingly small quantities and in a highly impure state. Therefore, very sensitive and specific techniques are required for their detection, characterization and purification. Such sensitivity and specificity is provided by the ability of receptors to bind certain ligands with very high affmity, and it is not surprising that most of the methods described in this volume depend upon this high affinity binding. The antigen-antibody interaction is of comparable sensitivity and speci ficity. Recently, a number of anti-receptor antibodies have been produced or found to occur spontaneously in auto-immune diseases. Undoubtedly, more will be produced in the future.

Taschenbuch. Zustand: Neu. Neuware -Membrane adsorbers with high contaminant-removal capabilities for a large variety of impurities in a wide operational window of pH and conductivity are of great interest in biopharmaceutical production. The understanding of the interaction of contaminants and biomolecules with membrane adsorbers is a crucial aspect in the development of new membranes and purification steps in downstreaming. In order to find the most effective ligands and purification conditions as well as the understanding of the process extensive experimental process development is necessary. To reduce the effort, an appropriate, application-oriented small-scale test method (High Throughput Screening) was established and evaluated for the investigation of membrane adsorbers. This enables the parallel characterization of properties of the adsorbent in order to reduce time and material consumption in membrane and process development. New approaches using salt tolerant membrane adsorbers were investigated which allow a separation of target molecules and contaminants at similar net charge of the protein surface.Books on Demand GmbH, Überseering 33, 22297 Hamburg 152 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -In this present volume, different approaches are detailed to produce membrane proteins, purify them, study their function, determine their structure, and model them in membrane. Since every membrane protein behaves mostly in a unique way /fashion, knowledge of guidelines and tricks may help to increase chances to express, purify and characterize a peculiar membrane protein. Production of correctly folded protein remains a challenge. Moreover, getting a functional and stable protein requires to optimize membrane mimicking environments that can be detergent or artificial membranes. In some cases, the finding of the correct ligand which will stabilize the desired conformation is needed. In other cases, stabilization can be obtained using specific antibodies. This volume also presents different techniques to analyze the functional status of membrane proteins. Written in the highly successful Methods in Molecular Biology series format, chapters in Membrane Protein Structure andFunction Characterization: Methods and Protocols provide different techniques to analyze the functional and structural status of membrane proteins.

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book highlights a comprehensive and systematic introduction to the science and technology of gas cleaning membranes. Starting from basic concepts and principles, the book covers the preparation methods, performance parameters, and advances in applications of different types of membrane materials.Industrial smoke and dust emissions are one of the main causes of atmospheric haze. How to strictly control the emission of ultrafine dust and achieve efficient and clean utilization of resources is a common problem faced by industries related to chemical engineering, energy, steel, metallurgy, and building materials. There is an urgent need for new separation technologies. The low efficiency of traditional dust removal technologies cannot meet increasingly strict emission requirements. Membrane technologies provide an effective approach for PM2.5 control with its high separation efficiency and low energy consumption. Especially for the purification of high-temperature gases, it can maximize the utilization of the physical sensible heat of the gas and achieve energy recovery.This book first introduces relevant concepts and terms, separation principles, structure characterization, and evaluation methods of gas cleaning membranes. According to the characteristics of application environments, the preparation methods, performance parameters and application progress of different types of membrane materials, including those for medium and low temperature gases, high temperature gases as well as multi-functional membranes, are described in detail. Relevant equipment and typical application cases in indoor air purification, medical, and industrial fields are discussed. The book also summarizes latest theoretical research frontiers and projects future development trends in this field.This book can be used as a valuable reference for undergraduate and graduate students in materials science, chemical engineering, environmental engineering and researchers engaged in the development of air filtration materials and gas purification technology.The English translation of this book, originally in Chinese, was facilitated by artificial intelligence. The content was later revised by the author for accuracy.
