Book Description
Modern communication systems are evolving very quickly and tunable Radio Frequency (RF) components are needed to utilize the spectrum more effectively. Recent developments in small size and tunable microwave/RF components are attractive for communication and radar applications for industrial, civilian, and military purposes. Different frequency tuning methods of electrical, mechanical, optical, acoustic, and magnetic are employed for dual frequency of operation. New manufacturing methods are being continuously improved with great interest in additive manufacturing. This PhD thesis work focuses on design and frequency tuning of passive RF circuits using magnetic flux control of ferroic nanomaterials fabricated using additive manufacturing. In particular, the focus of the thesis is using nanoparticles of ferromagnetic Iron-Cobalt (Fe60Co40) and Cobalt ferrites (CoFe2O4) considered for their electromagnetic properties. Compared to ferroelectric materials, the tuning control circuit of ferro/ferrimagnetic materials can be designed without adding parasitic effects. The extracted electromagnetic properties of the realized composites are refraction index of nFeCo=4 and nCoFeO=2, magnetization saturation of MFeCo=198 emu/g and MCoFeO=46.8 emu/g, loss tangents of tanÎþFeCo

Book Description
Following an introduction to biogenic metal nanoparticles, this book presents how they can be biosynthesized using bacteria, fungi and yeast, as well as their potential applications in biomedicine. It is shown that the synthesis of nanoparticles using microbes is eco-friendly and results in reproducible metal nanoparticles of well-defined sizes, shapes and structures. This biotechnological approach based on the process of biomineralization exploits the effectiveness and flexibility of biological systems. Chapters include practical protocols for microbial synthesis of nanoparticles and microbial screening methods for isolating a specific nanoparticle producer as well as reviews on process optimization, industrial scale production, biomolecule-nanoparticle interactions, magnetosomes, silver nanoparticles and their numerous applications in medicine, and the application of gold nanoparticles in developing sensitive biosensors.

Book Description
Nanoalloys: From Fundamentals to Emergent Applications presents and discusses the major topics related to nanoalloys at a time when the literature on the subject remains scarce. Particular attention is paid to experimental and theoretical aspects under the form of broad reviews covering the most recent developments. The book is organized into 11 chapters covering the most fundamental aspects of nanoalloys related to their synthesis and characterization, as well as their theoretical study. Aspects related to their thermodynamics and kinetics are covered as well. The coverage then moves to more specific topics, including optics, magnetism and catalysis, and finally to biomedical applications and the technologically relevant issue of self-assembly.With no current single reference source on the subject, the work is invaluable for researchers as the nanoscience field moves swiftly to full monetization. - Encapsulates physical science of structure, properties, size, composition and ordering at nanoscale, aiding synthesis of experimentation and modelling - Multi-expert and interdisciplinary perspectives on growth, synthesis and characterization of bimetallic clusters and particulates supports expansion of your current research activity into applications - Synthesizes concepts and draws links between fundamental metallurgy and cutting edge nanoscience, aiding interdisciplinary research activity

Book Description
Properties of nanosilicon in the form of nanoparticles, nanowires, nanotubes, and as porous material are of great interest. They can be used in finding suitable components for future miniature devices, and for the more exciting possibilities of novel optoelectronic applications due to bright luminescence from porous silicon, nanoparticles and nanowires. New findings from research into metal encapsulated clusters, silicon fullerenes and nanotubes have opened up a new paradigm in nanosilicon research and this could lead to large scale production of nanoparticles with control on size and shape as well as novel quasi one-dimensional structures. There are possibilities of using silicon as an optical material and in the development of a silicon laser. In Nanosilicon, leading experts cover state-of-the-art experimental and theoretical advances in the different forms of nanosilicon. Furthermore, applications of nanosilicon to single electron transistors, as photonic material, chemical and biological sensors at molecular scale, and silicon nanowire devices are also discussed. Self-assemblies of silicon nanoforms are important for applications. These developments are also related to cage structures of silicon in clathrates. With an interesting focus on the bottlenecks in the advancement of silicon based technology, this book provides a much-needed overview of the current state of understanding of nanosilicon research. - Latest developments in nanoparticles, nanowires and nanotubes of silicon - Focus on nanosilicon - a very timely subject attracting large interest - Novel chapters on metal encapsulated silicon clusters and nanotubes
