Porous Membranes - Annarosa Gugliuzza - Bog

The purpose of this book is to give a global vision of basic concepts, featured manufacturing approaches and potential applications where the control of pore size and shape and distribution can be decisive for the success of a membrane process. It describes how to manage materials on molecular to macro scale for achieving high-defined architectures on large scale, thus enabling one to reach new productivity/efficiency trade-off for several advanced applications. The reader is encouraged to use this cross-disciplinary discussion for his own research or investment, thus stimulating reflections and new purposes, which may open new routes in using the membrane science in some expanding fields, including environment, energy, food and health. Advances and innovation are the central ideas of the book, providing a useful indication to solve current critical aspects and overcome existing bottlenecks in the extensive control of structural features of targeted membranes as well as in the potential scale up of developed and promising manufacturing techniques. Through the book, the reader will have the opportunity to understand the advanced techniques dedicated to the preparation of membranes with defined pore structure, as well as about the capability of a membrane to separate molecular species depending on the free pathways throughout it.
