60 Years of the Loeb-Sourirajan Membrane: Principles, New Materials, Modelling, Characterization and Applications bring forth theoretical advances, novel characterization techniques, materials development, advanced treatment processes, and emerging applications of membrane-based technologies. The trigger for writing this book is the 2020, 60th anniversary of the first asymmetric polymeric membrane invented by Dr. Sidney Loeb and Dr. Srinivasa Sourirajan (University of California, Los Angeles, USA) on the breakthrough discovery of the semipermeable membrane for seawater desalination. The book places emphasis on the advances of organic and inorganic membranes in different fields, covering not only the primary application of membranes for water and wastewater treatment but also other applications dealing with energy conversion and storage, organic solvent purification, gas separation, and biomedical processes. Provides a comprehensive overview on membrane technologies from the fundamental knowledge of fabrication principle and separation mechanisms to a wide range of applications, including new/emerging processes Covers the use of new/advanced materials (both organic and inorganic), novel membrane fabrication techniques, and cutting-edge characterization methods for the development of advanced membranes Includes advances in computational modeling and simulation of membrane processes.

In recent years, major concerns have been expressed about long-term derangements in hemodialysis patients and possible clinically relevant blood-membrane interactions. Preliminary studies employing biocompatible membranes and antioxidant agents such as vitamin E have demonstrated significant improvements in patient organ function and hemopoietic capacity with increased hematocrit and quality of life. Using a new technology, vitamin E has now been successfully bound to the inner surface of a hollow-fiber membrane, so that the patient's blood is flowing in contact with a layer of antioxidant agent covering the inner surface of the membrane in the hemodialyzer. The opening chapters of this publication give an overview on oxidant stress and the role of vitamin E as antioxidant agent and elaborate on technical aspects, hydraulics and permeability characteristics of the membrane in question. The main part is dedicated to the hemocompatibility of the membrane, its effect on erythrocyte morphology and survival and the impact on white cell and platelet function. The metabolic effects and the antioxidant impact of the vitamin E-coated membrane are presented in the last part of the book. Intended as a reference tool for professionals, students and fellows involved in the care of end-stage renal disease patients, it is also hoped that this book serves as a starting point for further speculations and research in the field.

Membrane Engineering in the Circular Economy: Renewable Sources Valorization in Energy and Downstream Processing in Agro-food Industry describes the modification of the general concept of "waste," including waste valorization as added-value products that are useful for energy production and biotechnology industries. Speaking to the relevance of this new vision, the book highlights the fundamentals of membrane operations in the exploitation of renewable sources for energy production and the valorization of agro-food waste at the industrial level.
