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.

As with many spheres of public life, public diplomatic communication is being transformed by the boom of social media. More than 165 foreign governmental organisations in China have embarked on the use of Weibo (a hybrid of Facebook and Twitter in China) to engage with Chinese citizens and reach out to youth populations, one of the major goals of current public diplomacy efforts. This exciting new pivot, based on systemic research of Weibo usage by embassies in China, explores the challenges and the limits that the use of Chinese Weibo (and Chinese social media in general) poses for foreign embassies, and considers ways to use these or other tools. It offers a systematic study of the effectiveness and challenges of using Weibo for public diplomatic communication in and with China. Addressing the challenges of e-diplomacy, it considers notably the occurrence of cyber-nationalism on Weibo and encourages a critical look at its practice, arguing how it can contribute to the goals of public diplomacy.
