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.

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.

by Jinshan YueNeural network (NN) algorithms are driving the rapid development of modern artificial intelligence (AI). The energy-efficient NN processor has become an urgent requirement for the practical NN applications on widespread low-power AI devices. To address this challenge, this dissertation investigates pure-digital and digital computing-in-memory (digital-CIM) solutions and carries out four major studies. For pure-digital NN processors, this book analyses the insufficient data reuse in conventional architectures and proposes a kernel-optimized NN processor. This dissertation adopts a structural frequency-domain compression algorithm, named CirCNN. The fabricated processor shows 8.1x/4.2x area/energy efficiency compared to the state-of-the-art NN processor. For digital-CIM NN processors, this dissertation combines the flexibility of digital circuits with the high energy efficiency of CIM. The fabricated CIM processor validates the sparsity improvement of the CIM architecture for the first time. This dissertation further designs a processor that considers the weight updating problem on the CIM architecture for the first time. This dissertation demonstrates that the combination of digital and CIM circuits is a promising technical route for an energy-efficient NN processor, which can promote the large-scale application of low-power AI devices.

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.
