Four typical kinds of crop seeds were studied as non-metallic bio-precursors to synthesize Biogenic Nitrogen-Phosphorous-codoped ZnO (BNP-ZnO). The as-prepared BNP-ZnO samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscope (FT-IR) and UV Vis spectroscopy. The results show that the as-synthesized nanomaterials have pure hexagonal wurtzite structure. Also the crystalline formation of ZnO and the absorbed species on the nanocrystals were observed. In the experiments it was found that the absorption edges of BNP-ZnO were extended to visible light compared to synthesized ZnO. Furthermore, experiments of crystal violet (CV) degradation under sunlight irradiation indicate superior photocatalytic activity of BNP-ZnO, of which the degradation rate is almost four times that of synthesized ZnO.

This book discusses the extremophiles explored for biosynthesis of nanoparticles. Nanotechnology is a widely emerging field involving interdisciplinary subjects such as biology, physics, chemistry and medicine. A wide variety of microorganisms, such as bacteria, fungi and algae are employed as biological agents for the synthesis of nanoparticles. Novel routes by which extremophiles can be employed to generate nanoparticles have yet to be discovered. The book is divided into 5 major chapters: (1) Major types of nanoparticles in nanotechnology (2) Diversity of microbes in the synthesis of nanoparticles (3) Extremophiles in nanoparticle biosynthesis (4) Applications of nanoparticles produced by extremophiles (5) Challenges and Future perspectives

Functionalized Nanomaterial-Based Electrochemical Sensors: Principles, Fabrication Methods, and Applications provides a comprehensive overview of materials, functionalized interfaces, fabrication strategies and application areas. Special attention is given to the remaining challenges and opportunities for commercial realization of functionalized nanomaterial-based electrochemical sensors. An assortment of nanomaterials has been investigated for their incorporation into electrochemical sensors. For example, carbon- based nanomaterials (carbon nanotube, graphene and carbon fiber), noble metals (Au, Ag and Pt), polymers (nafion, polypyrrole) and non-noble metal oxides (Fe2O3, NiO, and Co3O4). The most relevant materials are discussed in the book with an emphasis on their evaluation of their realization in commercial applications. Application areas touched on include the environment, food and medicine industries. Health, safety and regulation considerations are touched on, along with economic and commercialization trends. Introduces the principles of nanomaterials for electrochemical sensing applications Reviews the most relevant fabrication strategies for functionalized nanomaterial-based electrochemical sensing platforms Discusses considerations for the commercial realization of functionalized nanomaterial-based electrochemical sensors in the environment, food and point-of-care applications

Membranes have emerged over the last 30 years as a viable water treatment technology. Earth's population is growing and the need for alternative ways to generate potable water is rising. The recent advent of nanotechnology opens the door to improving processes in membrane technology, which is a promising step on the way to solving the earth's potable water problem. Current performance is enhanced and new concepts are possible by engineering on the nanoscale. This book presents key areas of nanotechnology such as fouling tolerant and robust membranes, enhanced destruction of pollutants and faster monitoring of water quality. 'Functional Nanostructured Materials and Membranes for Water Treatment' is part of the series on Materials for Sustainable Energy and Development edited by Prof. G.Q. Max Lu. The series covers advances in materials science and innovation for renewable energy, clean use of fossil energy, and greenhouse gas mitigation and associated environmental technologies.
