This book describes the essential characteristics of graphene, graphene oxide, reduced graphene oxide, and its nanocomposite and their applications in water and wastewater treatment and other environmental issues. The book introduces each topic in detail, discusses the basic principles, and analyzes and summarizes recent developments in the field. Various topics covered in this book include role of graphene as a potential material in photocatalytic organic pollutant degradation, water splitting applications, capacitive de-ionization techniques, air purification, gas adsorption, and decontamination of pathogenic microorganisms. Given the contents, the book is useful for students, researchers, and professionals working in the area environmental science and materials, especially graphene oxide, graphene, and graphene nanocomposite.

Written by a group of world-renowned experts, the second volume in this groundbreaking set continues where the first volume left off, focusing on fermentation products that contribute to human welfare across a variety of industries. Green technologies are no longer the "future" of science, but the present. With more and more mature industries, such as the process industries, making large strides seemingly every single day, and more consumers demanding products created from green technologies, it is essential for any business in any industry to be familiar with the latest processes and technologies. It is all part of a global effort to "go greener," and this is nowhere more apparent than in fermentation technology. This second volume in the groundbreaking new set, High Value Fermentation Products, focuses on industries that a concerned with human welfare, including the leather industry, textiles, pharmaceutical and medical, food processing, and others. Covering topics such as chitin and chitosan, microbial polyhydroxyalkanoates, propanediol, and many others, the editors and contributors have contributed to an extremely important facet of chemical and process engineering and how to move these industries into a much more sustainable and environmentally conscious direction. From converting waste into apparel to creating healthier foods and more effective medicines, this is truly a monumental work that is a must-have for any chemical engineer, scientist, or chemist.

Green technologies are no longer the "future" of science, but the present. With more and more mature industries, such as the process industries, making large strides seemingly every single day, and more consumers demanding products created from green technologies, it is essential for any business in any industry to be familiar with the latest processes and technologies. It is all part of a global effort to "go greener," and this is nowhere more apparent than in fermentation technology. This book describes relevant aspects of industrial-scale fermentation, an expanding area of activity, which already generates commercial values of over one third of a trillion US dollars annually, and which will most likely radically change the way we produce chemicals in the long-term future. From biofuels and bulk amino acids to monoclonal antibodies and stem cells, they all rely on mass suspension cultivation of cells in stirred bioreactors, which is the most widely used and versatile way to produce. Today, a wide array of cells can be cultivated in this way, and for most of them genetic engineering tools are also available. Examples of products, operating procedures, engineering and design aspects, economic drivers and cost, and regulatory issues are addressed. In addition, there will be a discussion of how we got to where we are today, and of the real world in industrial fermentation. This chapter is exclusively dedicated to large-scale production used in industrial settings.
