This book details first the chemistry of hydrogen production from biomass. Solutions to the CO2 issue are given in three chapters, which describe CO2 photo catalytic reduction, CO2 sequestration in terrestrial biomass, and plants as renewable fuels. Further chapters review the selenium cycle in ecosystems, advanced processes to treat water and ecological ways to dye textiles. Society growth during the last century has almost entirely relied on the carbon economy, which is the use of fossil fuels for energy and materials. The carbon economy has provided and will still provide many benefits. However, the increasing use of fossil fuels is partly responsible for the increase of atmospheric CO2 concentrations and in turn, global warming. There is therefore an urgent need for cleaner fuels such as hydrogen, as well as a need for a carbon neutral economy where each emitted CO2 molecule is fast sequestered in plants, algae, soils, sub soils and sediments.

Advanced bionanocomposite materials continue to be increasingly popular and are important for a wide range of scientific and engineering applications. In the race to exploit the unique mechanical, thermal, and electrical properties of bionanocomposite materials, researchers need to address new challenges in predicting, understanding, and managing the potentially adverse effects these materials could have on the environment and human life. This book focuses on the fundamentals of bionanostructured materials and bionanocomposites. It deals with some recent developments in the synthesis and characterization of bionanomaterials as well as their incorporation into polymer matrixes. The biological applications of bionanomaterials are also discussed in detail, along with the synthesis of bionanostructured materials and bionanocomposites, reviews of food packing, water remediation, heavy metal ion adsorption from wastewaters, and other industrial applications. This book is aimed at beginners in this field as well as advanced undergraduate- and graduate-level students of materials science and researchers working in the fields of bionanocomposites, nanotechnology, and analytical chemistry, especially those with an interest in materials for analytical applications.

Environmental chemistry is a fast developing science aimed at deciphering fundamental mechanisms ruling the behaviour of pollutants in ecosystems. Applying this knowledge to current environmental issues leads to the remediation of environmental media, and to new, low energy, low emission, sustainable processes. Chapters review analysis and remediation of pollutants such as greenhouse gases, chiral pharmaceuticals, dyes, chlorinated organics, arsenic, toxic metals and pathogen in air, water, plant and soil. Several highlights include the overlooked impact of air pollutants from buildings for health risk, innovative remediation techniques such as bioreactors for gas treatment, electrochemical cleaning of pharmaceuticals, sequestration on Fe-Mn nodules, phytoremediation and photocatalytical inactivation of microbial pathogens. This book will be a valuable source of information for engineers and students developing novel applied techniques to monitor and clean pollutants in air, wastewater, soils and sediments.

Plant Nutrients and Abiotic Stress Tolerance

This book discusses many aspects of plant-nutrient-induced abiotic stress tolerance. It consists of 22 informative chapters on the basic role of plant nutrients and the latest research advances in the field of plant nutrients in abiotic stress tolerance as well as their practical applications. Today, plant nutrients are not only considered as food for plants, but also as regulators of numerous physiological processes including stress tolerance. They also interact with a number of biological molecules and signaling cascades. Although research work and review articles on the role of plant nutrients in abiotic stress tolerance have been published in a range of journals, annual reviews and book chapters, to date there has been no comprehensive book on this topic. As such, this timely book is a valuable resource for a wide audience, including plant scientists, agronomists, soil scientists, botanists, molecular biologists and environmental scientists.

This book presents the dynamic role of algae in a sustainable environment. Two major aspects, namely bioenergy and bioremediation, have been elaborated in various chapter contributed by scientists and teachers from different geographical areas throughout the world. Algal biofuels is an emerging area of equal interest to researchers, industries, and policy makers working or focusing on alternative (i.e. renewable) fuels. Algae have been an area of interest due to their wide range of applications. Over the last 5 decades, eukaryotic algae have been used in the aquaculture industry as feed for invertebrates, providing a rich source of antioxidants, dietary fiber, minerals and protein. More recently, there has been a focus on the use of algal biomass in the development of alternative fuels. The extraction of oil from algae has been widely explored as a much more viable feedstock than plant-based oils in large-scale fuel production. using algae as feedstock has the advantages that it doesn’t require arable land and that wastewater can be used as a source of nutrients in their culture. The multifunctional approach of algae includes pollution remediation, carbon sequestration, biofuels production, and delivery of value-added products. However, there are still some obstacles that need to be overcome to make their use as potential feedstock for biofuels techno-economically feasible. In order to maintain the sustainability aspect of algal biofuels, various aspects have to be studied and critically analyzed to assess the long-term sustainability of algal derived biofuels. This book discusses the role of algae as a promising future feedstock for biofuels. They are known to sequester carbon in much larger amounts than plants and as such the book also describes their phycoremediation potential for conventional as well as emerging contaminants. It describes the role of anaerobic digestion in algal biorefineries; bioreactions and process parameters; biogas recovery and reuse. The role of algal biofilm based technology in wastewater treatment and transforming waste into bio-products is discussed, and remediation of sewage water through algae is assessed. The book also describes the production of biohydrogen, bio-oil, biodiesel; and the major bottlenecks in their usage. The emerging characterization techniques of these biofuels (bio-oil and biodiesel) are described, as are the decolorizing potential of algae and the genetic engineering techniques that could enhance the production of lipids in algae. Other aspects of the book include the role of remote sensing technology in the monitoring of algae and a life cycle assessment of algal biofuels.
