Modified Clay and Zeolite Nanocomposite Materials: Environmental and Pharmaceutical Applications retraces the most important knowledge gaps that the scientific community is facing, including a drawback of real-world applications. This valuable resource explores the novel applications of this group of nanomaterials that can be suitably surface-modified to obtain properties that can be applied in environmental and pharmaceutical fields. For example, modification with surfactants has given new motivation to the study of these materials by producing an inversion in the ion exchange behavior from cationic to anionic. This strategy has paved the way for new uses highlighted in this timely resource. Explores the combination of both minerals (clay and zeolite) together, with their application in two broad areas of emerging research Explains better utilization and applications for modified clay and zeolite through detailed comparative studies Consolidates information on the modification and tuning of clay and zeolite materials for novelty applications Helps users in the selection of materials, surface features, and other functionalization for diverse applications

This book provides an authoritative review of the origin and extraction of strontium and its impact on the environment. It also presents the latest strontium decontamination and remediation strategies. Around the globe, nuclear power is being recognized as a major source of energy and is expected to play a crucial role in meeting the energy requirements of present day society. However, the pros and cons have to be considered, and the safe disposal of large amounts of radionuclide wastes is becoming a matter of great concern. These wastes encompass contaminants such as heavy metals and toxic substances, which may exist in solid, liquid or gaseous forms or a combination of these, and as such, their disposal requires particular attention. The book focuses on 90Sr, which is a predominant isotope of strontium and considered an intermediate level radioactive waste with a half-life of 28.8 years, average biological half-life of 18 years and 546 KeV decay energy. Written by expert contributors, it addresses occurrence, detection and extraction of strontium, the chemical and nuclear properties of strontium isotopes, the fate and migration of strontium in soil, its bioaccumulation, and its associated health impact, mechanistic toxicity response as well as related regulation and remediation. It appeals to scholars, scientists and environmental managers working with strontium contamination in the environment and its consequences.

Presenting an in-depth coverage, this textbook brings together and integrates key topics including water resources, wastewater, air, and solid waste in a single volume. The textbook introduces a unique approach that emphases on the water and wastewater treatments with its distribution system and engineering. It begins by discussing the public health and sanitation, then covers the wastewater collection system and design, wastewater characteristics, natural purification water, different wastewater treatments, industrial and rural wastewater. Finally, the emerging technologies in the reuse/recycle of waste and processes to conserve the environmental resources are discussed. The text will be useful for senior undergraduate and graduate students in the fields of civil and environmental engineering. Pedagogical features including solved problems, exercises and multiple-choice questions are interspersed throughout the book for better understanding. Discusses latest technologies and engineering design in water and wastewater management. Focusses on reuse and conservation of natural resources. Comprehensively covers topics on air pollution and noise pollution. Explains important topics including coagulation and flocculation, sedimentation, filtration, disinfection, water softening and water distribution. Includes pedagogical features including solved examples, exercises and multiple-choice questions with answers for better understanding of concepts.

Smart materials are used to develop more cost-effective and high-performance water treatment systems as well as instant and continuous ways to monitor water quality. Smart materials in water research have been extensively utilized for the treatment, remediation, and pollution prevention. Smart materials can maintain the long term water quality, availability and viability of water resource. Thus, water via smart materials can be reused, recycled, desalinized and also it can detect the biological and chemical contamination whether the source is from municipal, industrial or man-made waste. The 15 state-of-the-art review chapters contained in this book cover the recent advancements in the area of waste water, as well as the prospects about the future research and development of smart materials for the waste water applications in the municipal, industrial and manmade waste areas. Treatment techniques (nanofiltration, ultrafiltration, reverse osmosis, adsorption and nano-reactive membranes) are also covered in-depth. The chapters are divided into three groups: The first section includes the various carbon nanomaterials (such as carbon nanotubes, mixed oxides) with a focus on use of carbon at nanoscale applied for waste water research. The second section focuses on synthetic nanomaterials for pollutants removal. The third section highlights the bio-polymeric nanomaterials where the authors have used the natural polymers matrices in a composite and nanocomposite material for waste treatment. The large number of researchers working in the area will benefit from the fundamental concepts, advanced approaches and application of the various smart materials towards waste water treatment that are described in the book. It will also provide a platform for the researchers and graduate students to carry out advanced research and understand the building blocks.

Zeolites form a family of minerals which have been known since the 18th century, but they remained a curiosity for scientists and collectors until 60 years ago, when their unique physicochemical properties attracted the attention of many researchers. In the past 30 years there has been an ex traordinary development in zeolite science; six International Conferences on Zeolites have been held every 3 years since 1967, and a large number of interesting contributions have been published in their proceedings. Many books, written either by individual authors or by several authors under a leading editor, have been published on these interesting silicate phases, but none has been devoted specifically to natural zeolites, even though this theme may be of interest not only to earth scientists, but also to chemists, as the in formation obtained from natural samples completes and in tegrates the characterization of many zeolites. We are trying to fill this gap on the basis of 20 years of research on natural zeolites, which we performed at the University of Modena together with many friends and colleagues. If it is in general difficult to write a scientific book with out upsetting somebody, this is particularly true for a book on natural crystals, because mineralogy is an interdisciplin ary science which covers some fields of physics, chemistry, it is almost impossible to meet every petrology, geology, and requirement.

This volume presents the outcome of an Agriculture Workshop organized by the Gulf Research Centre Cambridge (GRCC) and held at Cambridge University, UK during the Gulf Research Meeting 11-14 July 2012. Co-directed by the editors, the workshop, entitled “Environmental Cost and Changing Face of Agriculture in the Gulf States” was attended by participants from Australia, Bahrain, India, Kuwait, Oman, Saudi Arabia, Turkey, UAE, UK and Morocco. These scientists, educators, researchers, policy makers and managers share their experience in agriculture in the Gulf States, with the aim of helping to improve agriculture production and thus bridge the gap between local production and the food import. The papers gathered here were presented at the workshop and have all passed through rigorous peer review by renowned scientists. The diverse papers present various aspects of agriculture production in the evolving face of climate change and dwindling water resources in the region. The book covers topics such as the prospects of agriculture in a changing climate; the potential of climate-smart agriculture; the impact of food prices, income and income distribution on food security; improved efficiency in water use; challenges in using treated wastewater in agriculture; investment in foreign agriculture and agricultural research and development. The papers span the nations of the Gulf Cooperation Council, with specific case studies set in Oman, Bahrain and Kuwait.
