Full Description
An accurate and up-to-date exploration of molecular and ionic transport phenomena through polymeric membranes
This book distinguishes itself by moving beyond a purely clinical, fact-delivery model. It combines robust, evidence-based information with a culturally aware and highly accessible writing style, making it not just an informative resource, but also an inspiring guide for all maternity caregivers.
In Molecule and Ion Transport Through Polymer Membranes, distinguished researcher Yong Soo Kang delivers an authoritative and organized resource about polymeric membrane technology. The book introduces the fundamentals of the transport phenomena of neutral molecules and ions as well as the underlying common principles between the two.
The author establishes a foundation for designing new polymeric materials using basic principles, like Fick's law, and to introduce a variety of fundamental theories and concepts about polymer structure and permeation properties. Readers will also find:
A thorough introduction to the underlying principles and experimental techniques necessary to study molecular and ionic transport processes
Comprehensive explorations of the separation and transportation of small molecules and ions by membranes
Practical discussions of the transport properties of neutral molecules and ions
Complete treatments of fundamental principles and theories relevant to mass transport through polymeric membranes
Perfect for polymer chemists, process engineers, electrochemists, membrane scientists, and materials scientists, Molecule and Ion Transport Through Polymer Membranes will also benefit mechanical and chemical engineers.
