Multi-material 3D Printing Technology introduces the first models for complex construction and manufacturing using a multi-material 3D printer. The book also explains the advantages that these innovative models provide at various points of the manufacturing supply chain. Innovations in fields such as medicine and aerospace are seeing 3D printing applied to problems that require the technology to develop beyond its traditional definitions. This groundbreaking book provides broad coverage of the theory behind this emerging technology, and the technical details required for readers to investigate these methods for themselves.

In addition to describing new models for application of this technology, this book also systematically summarizes the historical models, materials and relevant technologies that are important in multi-material 3D printing.

Introduces the heterogeneous object model for 3D printing Provides case studies of the use of hybrid 3D Printing to create gears and human bone Presents techniques which are easy to realize using commercial 3D printers

Membrane-Based Separation in Metallurgy: Principles and Applications begins with basic coverage of the basic principles of the topic and then explains how membrane technology helps in the development of new environmentally friendly and sustainable metallurgical processes.

The book features the principles of metallurgical process and how widely the membrane-based technology has been applied in metallurgical industry, including the basic principles of membrane-based separation in terms of material science, membrane structure engineering, transport mechanisms, and module design, detailed metallurgical process flowcharts with emphasis on membrane separations, current process designs, and describes problems and provides possible solutions.

In addition, the book includes specific membrane applications, molecular design of materials, fine tuning of membrane's multi-scale structure, module selection and process design, along with a final analysis of the environmental and economic benefits achieved by using these new processes.

Outlines membrane separation processes and their use in the field of metallurgy Includes case studies and examples of various processes Describes individual unit operations and sectors of extractive metallurgy in a clear and thorough presentation for students and engineers Provides a quick reference to wastewater treatment using membrane technology in the metallurgical industry Outlines the design of flowsheets, a topic that is not covered in academic studies, but is necessary for the design of working process Provides examples and analysis of the economic implications and environmental and social impacts

When public history was imported from the United States to China around the turn of the twenty-first century, it was introduced as a sub-field within history, and has developed along that path ever since. Professional historians in China, even some forward-looking ones, see public history as merely presenting a change in the patterns of participation in history-making. This book offers a sharply different view. It contends, essentially, that public history represents more than a research domain within history or within any existing discipline, nor does it fit into any established narratives, but rather, a fundamental change of the entire process of history-making in China. In this process, the public is prosuming history. Public history makes obsolete the old structure for building and acquiring historical knowledge: it challenges the old assumptions, supersedes the rigid academic hierarchy, and stirs the imaginations of the multitudes. With an assemblage of case studies, this work makes a case for a system view of public history making, or public history(ing), and launches a concept, complex public history, i.e. public history(ing) as complex adaptive systems.
