Plasma Processing of Nanomaterials available in PDF, EPUB and Kindle. We are at a critical evolutionary juncture in the research and development of low-temperature plasmas, which have become essential to synthesizing and processing vital nanoscale materials. More and more industries are increasingly dependent on plasma technology to develop integrated small-scale devices, but physical limits to growth, and other challenges, threaten progress. Plasma Processing of Nanomaterials is an in-depth guide to the art and science of plasma-based chemical processes used to synthesize, process, and modify various classes of nanoscale materials such as nanoparticles, carbon nanotubes, and semiconductor nanowires. Plasma technology enables a wide range of academic and industrial applications in fields including electronics, textiles, automotives, aerospace, and biomedical. A prime example is the semiconductor industry, in which engineers revolutionized microelectronics by using plasmas to deposit and etch thin films and fabricate integrated circuits. An overview of progress and future potential in plasma processing, this reference illustrates key experimental and theoretical aspects by presenting practical examples of: Nanoscale etching/deposition of thin films Catalytic growth of carbon nanotubes and semiconductor nanowires Silicon nanoparticle synthesis Functionalization of carbon nanotubes Self-organized nanostructures Significant advances are expected in nanoelectronics, photovoltaics, and other emerging fields as plasma technology is further optimized to improve the implementation of nanomaterials with well-defined size, shape, and composition. Moving away from the usual focus on wet techniques embraced in chemistry and physics, the author sheds light on pivotal breakthroughs being made by the smaller plasma community. Written for a diverse audience working in fields ranging from nanoelectronics and energy sensors to catalysis and nanomedicine, this resource will help readers improve development and application of nanomaterials in their own work. About the Author: R. Mohan Sankaran received the American Vacuum Society’s 2011 Peter Mark Memorial Award for his outstanding contributions to tandem plasma synthesis.

Plasma for Energy and Catalytic Nanomaterials available in PDF, EPUB and Kindle. The Special Issue “Plasma for Energy and Catalytic Nanomaterials” highlights the recent progress and advancements in the synthesis and applications of energy and catalytic nanomaterials by plasma. Compared with conventional preparation methods, plasma provides a fast, facile, and environmentally friendly method for synthesizing highly efficient nanomaterials. The synthesized nanomaterials generally show enhanced metal–support interactions, small-sized metal nanoparticles, specific metal structures, and abundant oxygen vacancies. The plasma method allows thermodynamically and dynamically difficult reactions to proceed at low temperatures due to the activation of energetic electrons. Despite the growing interest in plasma for energy and catalytic nanomaterials, the synthesis mechanisms of nanomaterials using plasma still remain obscure due to the complicated physical and chemical reactions that occur during plasma preparation. The Guest Editors and the MDPI staff are therefore pleased to offer this Special Issue to interested reader, including graduate and Ph.D. students, postdoctoral researchers, and the entire community interested in the field of nanomaterials. We share the conviction that the Issue can serve as a useful tool for updating the literature and to aid with the conception of new production and/or research programs. Further dedicated R&D advances are possible based on new instruments and materials under development.

Download and read online ebook Plasma based Synthesis and Modification of Nanomaterials write by Pawel Pohl. This book was released on 2020-05-12. Plasma based Synthesis and Modification of Nanomaterials available in PDF, EPUB and Kindle. This book, entitled “Plasma-Based Synthesis and Modification of Nanomaterials” is a collection of nine original research articles devoted to the application of different atmospheric pressure (APPs) and low-pressure (LPPs) plasmas for the synthesis or modification of various nanomaterials (NMs) of exceptional properties. These articles also show the structural and morphological characterization of the synthesized NMs and their further interesting and unique applications in different areas of science and technology. The readers interested in the capabilities of plasma-based treatments will quickly be convinced that APPs and LPPs enable one to efficiently synthesize or modify differentiated NMs using a minimal number of operations. Indeed, the presented procedures are eco-friendly and usually involve single-step processes, thus considerably lowering labor investment and costs. As a result, the production of new NMs and their functionalization is more straightforward and can be carried out on a much larger scale compared to other methods and procedures involving complex chemical treatments and processes. The size and morphology, as well as the structural and optical properties of the resulting NMs are tunable and tailorable. In addition to the desirable and reproducible physical dimensions, crystallinity, functionality, and spectral properties of the resultant NMs, the NMs fabricated and/or modified with the aid of APPs are commonly ready-to-use prior to their specific applications, without any initial pre-treatments.

Plasma Synthesis and Self-Assembly of Magnetic Nanoparticles available in PDF, EPUB and Kindle. Nanomaterials are important tools for enabling technological progress as they can provide dramatically different properties as compared to the bulk counterparts. The field of nanoparticles is one of the most investigated within nanomaterials, thanks to the existing, relatively simple, means of manufacturing. In this thesis, high-power pulsed hollow cathode sputtering is used to nucleate and grow magnetic nanoparticles in a plasma. This sputtering technique provides a high degree of ionization of the sputtered material, which has previously been shown to aid in the growth of the nanoparticles. The magnetic properties of the particles are utilized and makes it possible for the grown particles to act as building blocks for self-assembly into more sophisticated nano structures, particularly when an external magnetic field is applied. These structures created are termed “nanowires” or “nanotrusses”, depending on the level of branching and inter-linking that occurs. Several different elements have been investigated in this thesis. In a novel approach, it is shown how nanoparticles with more advanced structures, and containing material from two hollow cathodes, can be fabricated using high-power pulses. The dual-element particles are achieved by using two distinct and individual elemental cathodes, and a pulse process that allows tuning of individual pulses separately to them. Nanoparticles grown and investigated are Fe, Ni, Pt, Fe-Ni and Ni-Pt. Alternatively, the addition of oxygen to the process allows the formation of oxide or hybrid metal oxide – metal particles. For all nanoparticles containing several elements, it is demonstrated that the stoichiometry can be easily varied, either by the amount of reactive gas let into the process or by tuning the amount of sputtered material through adjusting the electric power supplied to the different cathodes. One aim of the presented work is to find a suitable material for the use as a catalyst in the production of H2 gas through the process of water splitting. H2 is a good candidate to replace fossil fuels as an energy carrier. However, rare elements (such as Ir or Pt) needs to be used as the catalyst, otherwise a high overpotential is required for the splitting to occur, leading to a low efficiency. This work demonstrates a possible route to avoid this, by using nanomaterials to increase the surface-to-volume ratio, as well as optimizing the elemental ratio between different materials to lower the amount of noble elements required.
