Preview Advances in Nanotechnology and the Environment

N A anoparticles and nano-sized materials created by nanotechnology d (NT) have been considered unique and sole solution to overcome the v limitations of other technologies and widen their applications. Although a n these materials have been widely used in environmental technology (ET), c most of environmental applications of nanoparticles were limited to the e fabrication of nano-sensors for the detection of volatile organic s compounds (VOC) and as nano-sized catalysts for air purification systems. i n So, the use of nanoparticles for the direct removal of pollutants from N contaminated soil and wastewater has been seldom reported. However, a environmental processes for soil remediation, wastewater treatment, n and air purification strongly need innovative new materials to o t highly improve their performance and efficiency. The demand e for materials created by NT in ET is, therefore, stronger than ever. c h n This book presents the possible applications of nano-sized materials in o all environmental processes, providing the most reliable guideline so l o far for the selection of nanomaterials to improve the efficiency g of environmental processes. It focuses on designing specific y nanomaterials for environmental processes and pollutants. It presents a the impact and influence of nanomaterials on the environment and discusses n d how to avoid causing secondary contamination by the use of nanomaterials. t The book provides proper information about nanomaterials for potential h e users who will use and apply nanomaterials in ET. E n v Juyoung Kim completed his PhD on the synthesis of i r amphiphilic polymeric networks and their applications in o 1996 under the supervision of Prof. Kyungdo Suh at Hanyang n m University, South Korea. He undertook a postdoctoral fellowship with Prof. Claude Cohen at Cornell University e Advances from 1996 to 1998. He then began an academic career as n t Assistant Professor of Advanced Materials Department at Samcheok National University, South Korea, and was promoted in 2010 to Full Professor with tenure. He has Nanotechnology in published 70 peer-reviewed journal publications and 7 patents. Currently, his research focuses on the synthesis J u of core-crosslinked amphiphilic polymer nanoparticles y using various amphiphilic reactive oligomers and o Environment u and the bridged organosilica precursor containing amphiphilic n g polymer chains and their applications for target drug K delivery, in vivo oxygen-sensing nanoparticles, and im antimicrobial nanocarriers.

Now the technologies based on nanoscience and nanotechnology are exerting a profound and strong impact on every field of conventional technology and science. Science and technology in the 21st century are evolving in four major directions: environmental technology, information technology, biotechnology, and nanotechnology. Technologies created and advanced by these four disciplines have continuously had an impact on daily life. Drug delivery systems, vaccines, animal cloning, genetically modified organisms, fuel cells, solar cells, electroluminescence devices, flexible displays, wireless telecommunications, World Wide Web, and so on, were created and brought to us by these technologies. There is no doubt that because of these four pillars of technology, humankind will experience an unprecedented technology-based life. The role of nanotechnology in advanced modern technologies is to provide materials as breakthrough and to materialize technology, and these materials have been considered the unique and sole solution to the limitations of other technologies and a means of widening their applications. Therefore, nanoparticles and nano-sized materials—such as nano-imprinting materials, nano-lithography materials, nano-sized sensors, as well as nano- sized detectors for biomolecules in DNA assay, immunoassay, and cell bio-imaging—have been widely used in biotechnology and information technology. However, little has been reported about the application of nanoparticles in environmental technology and about their influence on the environment. Most of the environmental applications of nanoparticles have been limited to the fabrication of nano-sensors for VOC detection and nano-sized catalysts for air purification systems. The use of nanoparticles for the direct removal of pollutants from the contaminated soil and wastewater has been viii Preface seldom reported. Environmental processes for soil remediation, wastewater treatment, and air purification strongly need innovative new materials to improve their performance and efficiency. Hence, the demand for materials created by nanotechnology in environmental technology is ever stronger than before. This book presents the possible applications of nano-sized materials in environmental processes. It is by far the most reliable guideline for the selection of nanomaterials to improve the efficiency of environmental processes and for designing nanomaterials for specific environmental processes and pollutants. The impact of nanomaterials on the environment has also been discussed in the book to help avoid causing secondary contamination by use of nanomaterials and to provide proper information about nanomaterials to potential users who wish to use and apply them in environmental technology. Chapter 1 AmphiphiliC OrgAniC NaNoparticles as NaNo- AbsOrbents fOr pOllutAnts Juyoung Kim Department of Advanced Materials Engineering, Kangwon National University, Samcheok, Kangwon 245-711, South Korea [email protected] Environmental engineers have invented very large numbers of processes and devices for removal of pollutants from various water phases and soils. Recently, material engineers and environmental engineers have begun fusing their technologies to improve efficiency of environmental process. Material engineers found new applications of their materials, at the same time environmental engineers could enhance performance of their processes by just adding materials without big modification in the process (technically no modification). Users and engineers keep trying to find magical materials that can improve the efficiency and reduce the cost of their environmental engineering process by just adding small amount of magical materials. That is, antifouling agent, coagulants (aluminum sulphate, ferrous sulphate, ferric chloride, polyelectrolyte), sedimentation, activated carbon, surfactants, microorganism, etc., have been used for enhancing efficiency of environmental process, which is running in real field [1–3].
