High Electrical Resistance Ceramics: Thermal Power Plant Waste Resources
by Muktikanta Panigrahi Ratan Indu Ganguly Radha Raman DashHIGH ELECTRICAL RESISTANCE CREAMICS Pond and fly ash waste materials generated by thermal power stations pollute the environment; this book demonstrates how the utilization of these materials minimizes environmental pollution and conserves land for cultivation. This book highlights the preparation of ceramics using pond/fly ash. Since the mullite phase formed by heat treatment improves the properties of ceramics, current investigations will perhaps be the first attempt to develop ceramics using pond ash. The properties of components made with these developed ceramics are found to be comparable to those made with porcelain. The extensively reviewed chapters of this book illustrate the current status of research on these materials. At the end of each of the 10 chapters, conclusions are drawn which will benefit researchers working in this area. Subjects discussed include: The fundamentals of thermal power plant wastes; Different production methods of ceramics and various characterization techniques; The preparation of ceramics from fly ash and fly ash/kaolin composite; The production of ceramics using pond ash; The preparation and characterization of geopolymer from pond ash and the preparation of pond ash composite; Production of ceramic matrix composite (CMC) using pond ash and pyrophyllite; The preparation of ceramics using pond ash and k-feldspar mixture. Audience The book will be used by civil engineers in the construction and ceramic industries as well as the industrial waste sector. Researchers in materials science, structural, civil and electrical engineering, environmental science, and ceramic engineering, will also have interest. Industries that have an interest include construction, electrical, and ceramic industries as well as pollution and waste sectors.
High Electrical Resistant Materials: Ferrochrome Slag Resource Ceramics
by Muktikanta Panigrahi Ratan Indu Ganguly Radha Raman DashHIGH ELECTRICAL RESISTANT MATERIALS The book describes how the utilization of high-carbon slag/pond ash/fly ash for making value-added ceramics is useful for the electrical sectors. Since waste materials are currently endangering our environment, ways of utilizing them have become a global challenge. Currently, R&D work is being carried out to utilize these materials for producing value-added products. This book details the investigations to utilize fly ash (FA) and pond ash (PA) - both waste materials from thermal power plants - with high-carbon ferrochrome (HCFC) slag (by-product of the ferrochrome industry), for producing a novel material for ceramics. Kaolin/K-feldspar is mixed with PA/HCFC slag to produce ceramics with the formation of mullite. The FA/PA/HCFC slag-based ceramics can replace porcelain-based ceramics, and some permanent ceramic structures can be constructed with such wastes. Properties and structures made with ceramics are found to be comparable with those made with porcelain-based ceramics. Performances of these materials above ambient temperature have been evaluated and results indicate the possible replacement of porcelain with these newly invented ceramics. Audience The book will be used by electrical and civil engineers in the electrical, construction, and ceramic industries as well as the industrial waste sector. Researchers in materials science, structural, civil and electrical engineering, environmental science, and ceramic engineering, will also have high interest.

Recent important findings are robust superconductivity under extraordinarily high pressure or ion irradiation, possible unconventional superconductivity, enhancement of bulk superconductivity, and high critical current density. In this book, HEA superconductors are classified into two primary categories: The first class encompasses alloy systems characterized by body-centered cubic and hexagonal close-packed structures; and the second class comprises intermetallic types. In each of these classes, the authors expound upon the exotic properties, applications, and materials design, aligning with the overarching themes of their work. This book delivers a topical and timely discussion of superconductivity associated with the high-entropy state, the potential applications under consideration, and the intricacies of materials design.

High Entropy Alloys: A Machine-Generated Literature Overview
by Saurabh S. NeneThis book presents the result of an innovative challenge, to create a systematic literature overview driven by machine-generated content. Questions and related keywords were prepared for the machine to query, discover, collate and structure by Artificial Intelligence (AI) clustering. The AI-based approach seemed especially suitable to provide an innovative perspective as the topics are indeed both complex, interdisciplinary and multidisciplinary, for example, climate, planetary and evolution sciences. Springer Nature has published much on these topics in its journals over the years, so the challenge was for the machine to identify the most relevant content and present it in a structured way that the reader would find useful. The automatically generated literature summaries in this book are intended as a springboard to further discoverability. They are particularly useful to readers with limited time, looking to learn more about the subject quickly and especially if they are new to the topics. Springer Nature seeks to support anyone who needs a fast and effective start in their content discovery journey, from the undergraduate student exploring interdisciplinary content to Master- or PhD-thesis developing research questions, to the practitioner seeking support materials, this book can serve as an inspiration, to name a few examples. It is important to us as a publisher to make the advances in technology easily accessible to our authors and find new ways of AI-based author services that allow human-machine interaction to generate readable, usable, collated, research content.

Ultimately, each succeeded on her path to flight. These diverse high-flyers are dreamers and doers who believed, despite the odds, that soaring is possible.
High Frequency Acoustics in Colloid-Based Meso- and Nanostructures by Spontaneous Brillouin Light Scattering
by Tim StillThe present thesis deals with the exploration of phononic properties of meso- and nanostructured colloid-based composite materials at hypersonic (GHz) frequencies. The emerging field of phononics, the mechanical analogue of photonics, treats the propagation and manipulation of acoustic waves in structured materials. Due to their widely tunable properties (size, density, etc.) and their ability to self-assembly, polymer colloids are ideal systems to realize hypersonic phononics, which are investigated by Brillouin light scattering herein. Therefore, both the mechanical and physical properties of the individual colloidal particles, which manifest in their resonance vibrations (eigenmodes), as well as the acoustic propagation in colloidal structures have been investigated. This thesis already lead to several journal publications and seven presentations at international conferences, and was honored summa cum laude.
