Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book presents a collection of cross-disciplinary research, with contributions addressing all key features of the plant/microbe/ENP nexus in agro-ecosystems. The uptake, transport and transformation of nanoparticles in plants have attracted more and more attention in the past several years. Especially, the impact of Engineered Nanoparticles (ENPs) on bioprocesses; low-, medium- and high-level dose responses in the microbial community of soil; and long-, medium- and short-term exposure responses, particularly microbial nitrogen transformations, are just a few of the aspects involved. Since ENPs are used in many industries, including cosmetics, agriculture, medicine, food technology and waste management, their transport through biogeochemical cycles is an important focus of many studies today.Specifically, ENP-microbe interaction has been analysed with regard to disease treatment for plants; it plays a vital role in disease inhibition by releasing metalions that act through many pathways - e.g. reactive oxygen species (ROS) generation, DNA transformation and disruption of the cell cycle - to stop cell growth in the pathogen. Due to these properties, ENPs are also used as slow release or delayed release pesticides and fungicides, and as carrier systems for growth-promoting hormones. Despite their multiple uses in various industries, the negative effects of ENPs are still a major concern for the scientific community and consumers alike. For example, their transport to various food chains has been reported to have adverse effects. This raises a degree of doubt concerning a rapidly growing scientific field with major applications in many industries.From a sustainable development perspective and particularly to ensure food security in light of the uncertainty accompanying climate change, it is imperative to address this divergence by focusing on the plant/microbe/ENP nexus.

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Blue-Green Infrastructure (BGI) is now recognized as beneficial in terms of maintaining water flows and thermal comfort in urban areas. A framework of ecosystem services for urban settlements may be instrumental in bio-physical benefits as well as social and psychological benefits that will be assisting in adaptation and mitigating adverse effects of changing climate. Cities in developing countries, where the land cover is undergoing rapid transition, are characterized primarily by urban characteristics at the expense of natural ecosystems. The book aims to provide a state of the art of Urban Resilience and Sustainability linked to blue-green components of the urban environment. The challenges and opportunities in adopting the blue-greens as next generation infrastructure, particularly in the context of rampant urbanization and changing climate are also one of the focal areas of the book. The book also deals with multilevel community and stakeholders' participation in developing and managing Blue-Green Infrastructure in urban centres of developing countries.Currently, the focus of researches in urban ecosystem is moving towards exploring the role of blue-green components in ameliorating the negative consequences of urbanization and changing climate. This book bridges the knowledge gap between the existing understating of the role of blue and green infrastructure separately and in integration in city planning, particularly in mitigating and adapting to changing climate and environmental pollution.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book helps the readers get a holistic understanding of the emergence of biochar-nanocomposite research.The low and long-term exposure of persistent hazardous pollutants in environment is well known for damaging the water, soil, sediments, and living biota. Thus, it is a crucial step to eliminate these pollutants from environment regimes to prevent the on-site destruction or the transfer into the food chain. Biochar is a carbon-rich solid material generated through pyrolysis of biomass, and currently, it is covering the hotspot in environmental management of pollutants. It is being utilized for the efficient immobilization and sorption of organic pollutants, heavy metals, dyes, improvement of soil redox conditions, aggregate stabilization, photocatalytic degradation, and for carbon sequestration. The fascinating properties like surface area, porous structures, functional groups, and mineral components turn it into suitable candidate for the removal of various class of pollutants from environmental matrices. Different reactions like sorption, reduction, precipitation, solidification, and degradation are mainly responsible for the effective cleaning of xenobiotics from environment through biochar application. However, rapidly evolving contaminants in the environment have made the remediation more complex, expensive, and challenging. In view of these aspects, the modification of biochar through the doping of nanometals/metal oxides/surfactants/ or chemical entities will result in modified biochar with high surface area, more functional entities, improved physical, chemical, thermal, and mechanical characteristics with more adsorptive sites. Inclusion of these exclusive properties can be done through magnetic modification, impregnation of nanometals/ metal oxides/surfactants, amination, acid/base reactions, steam activation, etc. The resulted biochar-based nanocomposites have demonstrated a vital role in remediation of persistentorganic pollutants, radionuclei, and heavy metals through the various interaction mechanisms like surface complexation, pi-pi interaction, electrostatic interaction, hydrogen bonding, Fenton process, and photocatalytic degradation. Currently, advanced research work has been carried out for the designing of modified composites of biochar to achieve maximum removal efficiency, reusability, biotoxicity, and sustainability. Hence, for selective removal of pollutants through designed biochar surface with the focused experimentation toward optimization of feedstocks, process variables, appropriate impregnation of nanomaterials, interaction with secondary pollutants, physical environment, longevity, and regeneration will definitely pave the way for safe and commercial application of biochar-based nanocomposites.
