Additive Manufacturing (AM) is a highly promising rapid manufacturing process. Based on incremental layer-upon-layer deposits, three dimensional components of high geometrical complexity can be produced; applications ranging from aerospace and automotive to biomedical industries. Laser, electron beam and wire-based techniques are reviewed. Particular emphasis is placed on 3D inkjet printing of metals, which is reviewed here in great depth and for the first time. This is an ambient temperature technology which offers some unique advantages for printing ?metals and alloys, as well as composite and functionally graded materials. Material selection guidelines are presented and the various deposition techniques and post-printing treatments are discussed; together with the resulting properties of the printed components: Density, shrinkage, resolution and surface roughness, porosity-related and mechanical properties, as well as biological properties? The various metal printing techniques are compared with each other and case studies are referred to.
Structural health monitoring (SHM) is an automated approach to determine any changes in the integrity of a mechanical system. The SHM system gives information in real time and online.? The knowledge on Root Mean Square Deviation (RMSD) techniques is employed and presented in this writing. Besides that, SHM system in wind turbine system is becoming very important. This book places emphasize on the application of biocomposite turbine blades for vertical axis wind turbines. The dynamics characterization of mechanical system on biocomposite turbine blades is determined with several techniques. The SHM for biocomposite turbine blades is enhanced in order for it to become a micro energy harvester.
The formation of metallic glasses and dual-phase composite/hybrid materials is reviewed, as well as the glass transition process and the resulting structural phenomena. These materials exhibit high strength, extreme hardness, good wear resistance and large elastic deformation.? Due to their excellent structural, functional, magnetic, chemical and biological properties metallic glasses are suitable for a great many applications, including in such areas as microelectromechanical devices, pressure sensors, orthopaedic screws and precision surgical instruments.
Polymeric compounds are generally blended with inorganic/organic materials to prepare composites to tailor the desired properties for specific requirements. The present book reviews new research in the fields of composite green polymers for environmental applications, polyaniline based composites for wastewater treatment, smart polymeric coating materials, polymer decorated bimetallic nanosorbents for dye removal, fuel cell materials, polymeric membranes, green bio-nanocomposites and polymer based catalysts.
Cork and cork agglomerates are natural cellular materials that are receiving much interest in a number of technological applications, e.g. as Feedstock for the Additive 3D Printing Technology; Solar, Wind and Bioenergy applications; Sorbent for Pesticides and Heavy Metals; ?and Water Treatment. Experimental, analytical and computational research is reported, as well as new applications in fields ranging from design and architecture to mechanical, chemical, civil and electronics engineering.
Electrochemical capacitors or supercapacitors offer a number of advantages over batteries; they are more safe and reliable, charge quicker, have an indefinite lifespan, exhibit a high power density and a wide range of working temperature. Supercapacitors demonstrate an extraordinary potential in both consumer electronics and large-sized energy storage applications, e.g. in communications, transportation, aviation, and power industries. The book explores recent developments in the area of composite applications for supercapacitor electrodes based von conducting polymers, graphene, biomass, or carbonaceous quantum dots. Synthesis strategies of composite materials and electrode preparation methods are discussed in detail.
La valorización de los residuos industriales dentro del sector de la construcción ha constituido un gran esfuerzo técnico y científico en las últimas décadas, tratando de buscar nuevas materias primas que sustituyan en mayor o menor grado los recursos naturales utilizados. El objetivo fundamental de esta monografía es estudiar la viabilidad de utilizar los residuos de la industria cerámica sanitaria como árido grueso reciclado en la fabricación de hormigones estructurales.
A self-consistent, microscopic model of individual- and -reacted point defects requires a reliable connection with the experimentally deduced structural, spectroscopic and thermodynamic properties of the defect centres, to allow their unambiguous identification. Aim of this book is to focus on the properties of defects in semiconductors of the fourth group under a physico-chemical approach, capable to demonstrate whether the full acknowledgement of their chemical nature could account for several problems encountered in practice or would suggest further experimental or theoretical accomplishments. It will be shown how difficult the fulfilment of self-consistency conditions can be, even today, after more than four decades of dedicated research work, especially in the case of compound semiconductors (SiC in this book), but also in the apparently simplest cases of silicon and germanium also because microscopic models do not account, jet, for defect interactions in real solids.
In the modern world, the life style of humans is greatly influenced by electronic gadgets. These electronic gadgets need semiconducting and magnetic materials. In particular, the magnetic materials which find applications in almost all such gadgets need to be researched and better understood. Magnetism has diverse applications, from simple ?loadstone? to complex DNA sequencing.? The aim of this book is to describe the synthesis and characterization of various nano ferrite materials used for memory applications. It is now well established that materials synthesized in nanometer scale have novel properties compared to their bulk counterparts. The distinct feature of the book is the construction of charge density diagrams of ferrites by using the maximum entropy method (MEM). It is analyzed how the charge density distribution in the ferrite unit cell affects charge related properties.
