Understanding the Distinguishing Features of a Microbial Fuel Cell as a Biomass-Based Renewable Energy Technology -- Screening Microbes for Ice-Associating Proteins with Potential Application as 'Green Inhibitors' for Gas Hydrates -- Surface Reactions: Bio-catalysis an Emerging Alternative -- Enabling Simultaneous Reductions in Fuel Consumption, NO x , and CO2 via Modeling and Control of Residual-Affected Low Temperature Combustion -- Flexible Sunlight-The History and Progress of Hybrid Solar Lighting -- Synthesis, Characterization, and Application of Magnetic Nanocomposites for the Removal of Heavy Metals from Industrial Effluents -- Application of Bacterial Swimming and Chemotaxis for Enhanced Bioremediation. With increasing attention being paid to the changing environment and the underlining reasons from the change, scientists are working at a faster pace to invent technologies that could have a positive impact. This book exclusively focuses on the technologies that would be in the forefront in near to far future. Each and every article in the book is peer-reviewed and discusses the current environmental challenges, the novel innovation and future directions. The topics covered in the book include microbial fuel cells, hybrid solar lighting, bacterial swimming for environmental remediation, cleaner engines, nanoparticles for effluent treatment, surface catalysis and proteins as gas hydrates inhibitors. This book will be suitable for academicians, industries and governmental/non-governmental agencies in the field of environmental sciences and technology.
