Urbanization, industrialization, and unethical agricultural practices have considerably negative effects on the environment, flora, fauna, and the health and safety of humanity. Over the last decade, green chemistry research has focused on discovering and utilizing safer, more environmentally friendly processes to synthesize products like organic compounds, inorganic compounds, medicines, proteins, enzymes, and food supplements. These green processes exist in other interdisciplinary fields of science and technology, like chemistry, physics, biology, and biotechnology, Still the majority of processes in these fields use and generate toxic raw materials, resulting in techniques and byproducts which damage the environment. Green chemistry principles, alternatively, consider preventing waste generation altogether, the atom economy, using less toxic raw materials and solvents, and opting for reducing environmentally damaging byproducts through energy efficiency. Green chemistry is, therefore, the most important field relating to the sustainable development of resources without harmfully impacting the environment. This book provides in-depth research on the use of green chemistry principles for a number of applications.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Written by the founder of the field of carbon "quantum" dots (carbon dots) and related technology, this book outlines the principles of carbon dots and presents strong evidence for that small carbon nanoparticles and by extension carbon dots represent the nanoscale carbon allotrope at zero-dimension.

Experimental approaches and techniques for the dot synthesis and some related major issues are discussed in detail. The photoexcited state properties, especially the bright and colorful photoluminescence emissions, and photoinduced redox characteristics of carbon dots are presented, and so are their advantages over semiconductor quantum dots as well as fullerenes. Carbon dots are also compared with "graphene quantum dots", for which a unified mechanistic understanding is proposed. Finally, a broad range of applications of carbon dots and their derived hybrid nanostructures in biomedical, renewable energy, food and environmental safety, and other technologies are highlighted. The book concludes with a discussion on the excellent potential and opportunities for further research and development.

This book assesses the current development and potential applications of nanoparticle technology in oil industry and explores new research directions in this frontier field. It outlines the theory and practical challenges of the nanoparticle colloidal behavior in oil matrixes and aqueous solutions, the interactions between rock and nanofluid, nanoparticles and asphaltenes, and the surface phenomena relevant to the application of this technology. The book also describes the transport behavior of nanoparticles in oil/sand media for in-situ upgrading and recovery of heavy oil. Currently, the main objectives of applying nanoscale materials in oil industry are the remediation of formation damage, the improvement of energy efficiency, the abatement of environmental footprints and the increment of recovery factors of oil reservoirs, to name a few. The book consists of 15 chapters with contributions by leading experts in the topics of fabrication methods, opportunities and challenges in the oil & gas industry, modeling and application of nanofluids in the field and environmental applications of nanoparticles. The growing demand for oil has led to the need to exploit unconventional oil resources, such as heavy and extra-heavy crude oil. However, in the current context, upgrading and recovery of heavy oil are highly energy and water intensive, which consequently results in environmental impacts. Therefore, it is necessary to search for new ideas and alternatives in the field of in-situ and ex-situ upgrading and recovery to improve current technologies and make them both environmentally sound and cost-effective. Research conducted by the authors and numerous other researchers has shown that nanoparticle technology could be successfully employed for enhancing the upgrading and recovery of heavy oil with cost-effective and environmentally friendly approaches. Examples on the applications of nanoparticles in heavy oil include the adsorption, oxidation, and gasification/cracking of asphaltenes, a problematic constituent present in heavy oils; in-situ upgrading of the Athabasca bitumen by multi-metallic in-situ prepared nanocatalysts; the inhibition of precipitation and deposition of asphaltnes; and the enhanced perdurability against asphaltene damage in oil sands porous media by injection of nanofluids; sequestration of oil from spilled by nanoparticles, cleaning up oil sand process affected water by integrating nanoparticle with conventional treatment processes, etc.
