The discovery of the Higgs boson in 2012, the culmination of a decades-long search, is one of the singular triumphs of particle physics. Advanced experiments at the Large Hadron Collider at CERN (the Conseil Européen pour la Recherche Nucléaire) near Geneva detected the long-hypothesized particle, resulting in the 2013 Nobel Prize in Physics. Drawing on two and a half years of in-depth fieldwork spent among CERN’s research community during this critical period, Arpita Roy offers a rich analysis of science in the making.To what extent are scientific discoveries a matter of empirical findings? How do scientists at the farthest reach of abstraction understand their work? Unfinished Nature delves deep into this particle physics laboratory to distinguish the modes of reasoning that animate scientific discoveries and innovations. Demonstrating a deep knowledge of both contemporary physics and the methods of qualitative social science, Roy considers what scientists have to say about their commitments and concerns, the sources and vision guiding their experiments, and the questions they ask of themselves and others. In so doing, she argues that finding new facts in experimental physics turns on conceptual leaps, not necessarily empirical results. A sophisticated interdisciplinary ethnography of a scientific community, Unfinished Nature offers provocative insights into the nature and production of scientific knowledge.

This book focuses on green nanoremediation addressing aspects related to the use of nanomaterials generated through green synthesis protocols to efficiently restore polluted environs. Nanomaterials’ characteristics such as large surface area, capacity to easily reach into contaminated sites, good reactivity, and possibility of being developed to present photocatalytic activity and/or to deal with targeted substances by chemical surface modification are useful specially to perform remediation. As an alternative to conventional physicochemical methods, the green-based synthesis protocols reject the use of harmful reagents, prevent waste production, apply renewable energy source and/or materials, and consider in first place offering the smallest negative impact possible to living beings and to the ecosystem. Green synthesis in nanotechnology field involves the use of seaweeds, bacteria, cyanobacteria, yeasts, fungi, plants (living ones, biomass, extracts) and/or bio-derived products to generate the nanomaterials. The introductory chapter will be dedicated to nanomaterials’ characteristics that enable them to be used in environmental remediation. The first part of the book will be dedicated to organic and inorganic pollution and the threats they pose to living forms; advantages, disadvantages and mechanisms of nanoremediation; comparison between conventional strategies of environmental pollution remediation and the green nanoremediation; carbon-based and non-carbon-based green nanomaterials capable of promoting environs’ remediation; cost/benefits of using nanomaterials and nanoinformatics to a safe nanotechnology. The second part will be dedicated to green nanoremediation of water and soil, microbe-based, algae-based and plant-based synthesis of nanomaterials to nanoremediation. This part will also contain chapters dedicated to relevant nanomaterials for green nanoremediation protocols, nano-phytoremediation strategies, strategies to evaluate the efficiency of protocols related to this kind of remediation, main interactions of green nanomaterials and microbes during nanoremediation and, as a consequence of it, biocompatibility of green nanomaterials.

This book provides essential information on the role of phytonanotechnology in the removal of environmental pollutants and covers recent advances in experimental and theoretical studies on plant-derived nanoparticles. It also discusses their current and potential applications and challenges.The combination of nanotechnology and phytoremediation, which is called phytonanotechnology, have the potential to remove contaminants from the environment or degrade them. The efficiency of contaminant removal can be improved by combining both methods as they are complementary to each other.Phytonanotechnology offers the advantages of increased bioavailability, prolongation of heavy metal absorption time, and multiple metal removal, all contributing to improved efficacy and decreased toxicity in plants and surroundings. Therefore, there is immense scope for nature-derived molecules to be formulated into nanotechnology-based phytoremediation approaches targeting the specific heavy metal removal from effluents and surroundings. This encourages research initiatives to synthesize more phytonanotechnology based uptake plant systems with high efficiency. Efficient formulation targeting strategies and the evaluation of targeting efficiency of phytonanotechnology, conforming to international standards of their toxicology and biocompatibility, could pave the way for heavy metal uptake and removal by plant-based systems.This book serves as a valuable resource for postgraduate students, environmental scientists and materials scientists in academia and corporate research.
