Graphene Quantum Dots: Biomedical and Environmental Sustainability Applications provides an overview of fundamentals and advances in applications of graphene quantum dots. Concepts covered include a brief introduction on the topic, an overview of structure and chemistry, fundamental properties of different characterization techniques, methods for the preparation of graphene quantum dots, and recent and emerging applications in various fields including antimicrobial therapy, bioimaging, biomedical tools development and clean energy for environmental sustainability. The book is a critical resource in materials selection for biomedical and environmental sustainability applications as well as various advanced imaging, disinfectant and environmental remediation technologies. As such, it is suitable for those in academia working in the discipline of materials science and engineering and practitioners working on biomedical tool development and environmental remediation.

This book presents a picture of the advances in the research of theoretical and practical frameworks of wastewater problems and solutions. The book deals with a basic concept and principles of modern biological, chemical and technical approaches to remediate various hazardous pollutants from wastewater. The latest empirical research findings in wastewater treatment are comprehensively discussed. Examples of low-cost technologies are also included.The book is written for professionals, researchers, academics and students wanting to improve their understanding of the strategic role of environmental protection and advanced applied technologies.

Globally, most agronomic soils contain huge reserves of phosphorus, but the fixation and precipitation, cause a major deficiency of Phosphorus in soil, and in turn, hamper the growth of crops seriously. How to improve phosphorus fertilizer efficiency and utilize the potential nutrient in soil has therefore, long been a major concern for field practitioners. This has led to a search for eco-friendly and economically attractive alternative technology for improving crop production in low or even P deficient soils. In this context, natural soil inhabitants endowed with P-solubilizing activity, often termed phosphate-solubilizing microorganisms [PSM], provides a viable substitute to chemical P fertilizers. Inoculation of phosphate-solubilizing microorganisms, like, bacteria and fungi in soil has been shown to immensely affect the growth of plants by making not only P available to plants but also facilitate the growth of plants by other mechanisms leading to higher crop yields.
