Book Description
This book describes the fabrication of a frequency-based electronic tongue using a modified glassy carbon electrode (GCE), opening a new field of applying organic precursors to achieve nanostructure growth. It also presents a new approach to optimizing nanostructures by means of statistical analysis. The chemical vapor deposition (CVD) method was utilized to grow vertically aligned carbon nanotubes (CNTs) with various aspect ratios. To increase the graphitic ratio of synthesized CNTs, sequential experimental strategies based on response surface methodology were employed to investigate the crystallinity of CNTs. In the next step, glucose oxidase (GOx) was immobilized on the optimized multiwall carbon nanotubes/gelatin (MWCNTs/Gl) composite using the entrapment technique to achieve enzyme-catalyzed oxidation of glucose at anodic potentials, which was drop-casted onto the GCE. The modified GCE’s performance indicates that a GOx/MWCNTs/Gl/GC electrode can be utilized as a glucose biosensor with a high direct electron transfer rate between GOx and MWCNTs/Gl. It was possible to use the fabricated biosensor as an electronic tongue thanks to a frequency-based circuit attached to the electrochemical cell. The results indicate that the modified GCE (with GOx/MWCNTs/Gl) holds promising potential for application in voltammetric electronic tongues.

Book Description
This volume offers the latest theory, procedures, techniques and applications pertaining to the bioremediation of pesticides, as well as current case studies. The book is composed of chapters written by global experts and is divided into three topical sections. Section A deals with concepts and mechanisms of pesticides bioremediation; Section B examines latest tools and techniques; Section C offers global case studies of pesticides bioremediation. The novel methods described here are timely, as traditional pesticide usage leads to high wastage via decay, vaporization and seepage. This of course leads to environmental contamination and has necessitated the development and use of novel technologies like bioremediation for minimizing the impact of pesticides on the environment. This volume will be of relevance to academics, researchers and students who are working in the realm of pesticide bioremediation, and will enable policy makers and managerial experts across the globe in drafting policies and strategies for the management and treatment of pesticides.

Book Description
For decades an increasingly rapid urbanization pace, modern industrial development, and constantly intensive agricultural practices have caused controlled or uncontrolled release of hazardous contaminants that seriously threaten our environment. All natural spheres (atmosphere, hydrosphere, biosphere, lithosphere, and anthroposphere) seem to have been exposed to harmful practices and emerging research in nanomaterials is now trying to combat their adverse impact on physical ecosystems and organisms, as well as human health. In this context, pollution remediation at the nanoscale has come to the forefront for its potential to unlock sustainable, highly efficient, and cost-effective technologies, capable to restore in situ or ex situ land, water, and air resources. Nanotechnology to Monitor, Remedy, and Prevent Pollution covers design, fabrication, and extensive applications of engineered nanostructured materials in various shapes and morphologies (such as nanoparticles, wires, tubes, fibres) that, because of their size, surface-to-volume ratio, and high reactivity, function as catalysts and adsorbents of organic pollutants (aliphatic and aromatic hydrocarbons), gases, chemicals (arsenic, manganese, iron, nitrate, heavy metals), antibiotics, and biological entities (bacteria, viruses, parasites). Their integration with biotechnological processes for monitoring and prevention of pollution is also explored alongside the invisible dangers caused by noise. This is a valuable book for academics, researchers, undergraduate and postgraduate students working on environmental engineering for sustainability, environmental sciences, biotechnology, and nanotechnology.? - Comprehensively presents applications of state-of-the-art nanotechnologies and nanomaterials for control, prevention, and removal of persistent air, water, and soil pollutants. - Provides a new benchmark for pros and cons of established processes for nano remediation, revealing the importance of such research beyond national boundaries and policies. - Classifies noise as a contaminant and discusses how its real impacts on human and animal life can be limited through impedance-matching nanotechnology.
