Geopolymers and Other Geosynthetics by Mazen Alshaaer,Han-Yong Jeon Pdf
Geopolymers are applied to material classes that are chemically transformed from low crystallinity aluminusilicates to three-dimensional inorganic polymers (tectosilicates). The resulting material has properties similar to natural minerals, so it is called artificial rock. However, these materials exhibit a chemical composition and mineralogical structure similar to feldspar, feldspathoidal, and zeolites consisting of a polymeric Si–O– Al framework, with a microcrystalline or an amorphous structure. Although geopolymers have attractive engineering and environmental characteristics, there are some challenges in commercializing these materials. In this book, these challenges will be addressed along with introducing the functional geopolymers as an effective approach to commercializing these materials and making them economically feasible.

However, the mining activity is a significant cause of environmental degradation, including soils, atmosphere, water, solid wastes, changed topography, and health hazards. This book emphasizes value-added products from mining wastes and innovations for balancing environment, ecology, and economy. This book is designed for miners, policymakers, professionals, researchers, scientists, industrialists, and environmental agencies.
Smart Nanotextiles Wearable and Technical Applications This groundbreaking book comprehensively reviews the utilization of smart nanotextiles in various application areas by referring to requirements specific to various application fields, sharing the findings of some of the latest research efforts and state-of-art smart nanotextiles technologies, as well as providing insights relating to challenges and opportunities facing current and future smart nanotextiles. This book covers the emerging and exciting field of nanotextiles and their many applications. Smart nanotextiles form a novel group of materials that are utilized/can be utilized in an array of application areas, such as biomedicine (health monitoring, controlled drug release; wound care, and regenerative medicine), communication, sports, fashion, energy harvesting, protection, filtration, civil and geotechnical engineering, transportation, and so on, including wearable and technical fields. Whereas textiles provide a convenient platform for smart functionality, nanotechnology assures that the favorable characteristics of the textile structure are not impaired by the smart functioning components. Furthermore, based on the superior characteristics of nanostructured components in comparison to macromaterials and micromaterials, nanomaterials provide augmented smart functionality. However, despite the immense research efforts that have been devoted to smart nanotextiles, most of them have not yet transcended the commercialization stage due to high cost, difficulty in large-scale production, low reliability, and potential detrimental effects of nanomaterials on human health and the environment. The 12 chapters comprising this book are all written by subject-matter experts from around the world and discuss the next-generation products along with their challenges and opportunities. Audience Researchers, technologists, industrial engineers, and postgraduate students in the fields of textiles, intelligent materials, electronics, sensors, actuators, biomedicine, fashion, filtration, transportation, civil engineering, environmental engineering, communication, sports performance, and materials science, who have an interest in smart materials, nanotechnology and wearables.

Biosorption for Wastewater Contaminants by Rangabhashiyam Selvasembian,Pardeep Singh Pdf
Pollution due to various anthropogenic activities continues to increase. In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a variety of environments, both urban and rural. This book provides up-to-date information on wastewater contaminants, aimed at researchers, engineers and technologists working in this field. Conventional physicochemical techniques used to remove contaminants from wastewater include ion exchange, precipitation, degradation, coagulation, coating, membrane processes and adsorption. However, these applications have technological and economic limitations, and involve the release of large amounts of chemical reagents and by-products that are themselves difficult to remove. Biosorption - the use of organically generated material as an adsorbent – is attracting new research and scholarship. Thermally-treated calcined biomaterials may be treated to remove heavy metals from wastewater. To ensure the elimination of these contaminants, existing solutions must be integrated with intelligent biosorption functions. Biosorption for Wastewater Contaminants will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry.

Enhancing Resilience of Dryland Agriculture Under Changing Climate by Anandkumar Naorem,Deepesh Machiwal Pdf
This contributed volume describes management practices based on interdisciplinary and convergence science approaches from different disciplines of agricultural science to enhance the resilience of dryland agriculture. The main focus of this book is to address the current issues and trends along with future prospects and challenges in adopting salient agricultural management practices in drylands globally under a climate-change scenario. Climate change and global warming have profound repercussions on increasing frequency, severity, and duration of droughts and/or floods, which may have implications for future productivity of dryland agriculture, e.g., more water shortages or abundances and high or low runoff rates, diminished crop yields, and reduced water productivity. In past few years, many technological advancements and management strategies have been evolved to tackle the climate-induced risks of dryland agriculture considering interdisciplinary and convergence approaches that integrate knowledge from multi-disciplines. This book is an attempt to bridge the gap in literature by unraveling controversies and characteristics of dryland ecosystems under the changing climate and dealing with detailed procedures of applying the advanced practices adapted to climate change for management of dryland agriculture. This edited book is of interest to ecologists, economists, environmentalists, geologists, horticulturalists, hydrologists, soil scientists, social scientists, natural resource conservationists and policy makers dealing with dryland agriculture. This book offers a broad understanding of dryland agriculture and assists the reader to identify both the current as well as the probable future state of dryland agriculture in a global context.
Handbook of Nanofibers and Nanocomposites by Mohd Yusuf,Aminoddin Haji Pdf
Textiles with functional properties such as antimicrobial finishes, drug delivery, ultraviolet resistance, electrical conductivity, superhydrophilicity, superhydrophobicity, self-cleaning, EMI shielding, flame-retardance can be developed with the help of nanotechnology. Nanomaterials can be added to the textile materials at different stages of the production process, including spinning, finishing, and coating. Nanofibers are textile fibers that show enhanced properties due to larger surface area compared with ordinary textile fibers. They have diameters less than 1000 nm and can hold nanoparticles, drugs, extracts, essential oils, etc. in their polymeric matrix. They actually encapsulate these compounds and are able to control their release by delivering them only at the targeted sites. Recently, nanofibers and textile nanocomposites have attracted great interest in the industry and research, and electrospinning is the most famous among the several methods that have been developed for the fabrication of nanofibers. This book is a collection of the reviews on the recent advances in the fields of nanofibers, nanocomposites, and their applications in textiles as well as related fields.
