This book presents theoretical studies on ion diffusion in (Li O) (B O ) compounds and at the interfaces of Li O: B O nanocomposite. In recent years, ceramic oxides have attracted considerable attention due to their broad potential applications as advanced materials with controlled chemical, mechanical, electrical, magnetic, and optical properties. Many of these properties are attributed to the mobility of metal ions. Ion conductivity in ceramic oxides has been observed in single-phase systems as well as in composites of different components. Therefore, this book considers the study of defects and diffusion in single crystalline materials such as Li O, Li B O as well as nanocomposite materials of Li O-B O mixtures. The structural, energetic and electronic properties are investigated in order to observe their relationship with defects and diffusion in ceramic oxide materials. The results show that ionic conductivity is enhanced at the interfaces of a conductor-insulator mixture which may have a potential application in battery technology."

Completely up-to-date, this is the first comprehensive monograph on metal oxide varistors with a focus on microstructure, conduction mechanisms, device failures, ageing, additive impacts and future varistor systems. As such, it covers the fundamentals and applications of metal oxide varistors, including their macro-characteristics, microstructural properties and the device-internal physical and electrical mechanisms. The author reflects on the achievements made in varistor research and propose new approaches to analyze and predict the macro-characteristics, employing such methods as micro-contact measurements and numerical simulations. In addition, he looks at future directions for varistor research, such as ZnO varistors with a high voltage gradient and low residual voltage and further varistor types based on TiO2 and SnO2.

This book discusses the subject of pathways to a sustainable economy through science and technology innovations which are regarded as the important components of the ‘4th Industrial Revolution’. The volume has been developed from Bangladesh’s ‘Vision 2041’ agenda which includes development actions needed to catch up with more developed nations. Most importantly, the goals of the ‘Vision 2041’ have been taken from the dreams of the architect of independent Bangladesh, Bangabandhu (Friends of Bengal) Sheikh Mujibur Rahman. His dream was to make Bangladesh the Switzerland of Asia. The Father of Bangladesh Nation was killed by assassins’ bullets along with his most of the family members in August 1975. After his death, the nation moved backwards while recovering from nine months of liberation post war in 1971. Between 1975 and 1990 Bangladesh was ruled by military and quasi military governments. Bangladesh established a true democratic regime in 1996 with Sheikh Mujib’s daughter, Sheikh Hasina, who formed the government after 21 years with a mandate to realise the dreams of her father. Sheikh Hasina, had her own 20 year vision for Bangladesh, called, ‘Vision 2021’, with plans to make the nation poverty free by 2021. After a pause between 2001 and 2008, Sheikh Hasina returned to power in 2009. Under her consecutive three terms she brought Bangladesh back on track and Bangladesh is one of the nations which reduced poverty half under MDGs by 2015. During her third consecutive term Sheikh Hasina, is on the way to transforming Bangladesh into a ‘middle income’ nation by 2021. This volume aims to identify and mitigate the challenges of ‘4th Industrial Revolution’ investigating the areas of science and technology innovations for Bangladesh and for other parts of the world keeping in mind establishing a sustainable economy under UN agendas to 2030 (SDGs). The primary audience for this book are UN development agencies, academic institutions, government policymakers and business leaders of the more developed and developing nations alike.

This book contains the proceedings of the international workshop on global sustainability held in Benevento, Italy, on February 2014. The proceedings consist of 10 invited and contributed papers related to the broad range of aspects of sustainability in a global scenario including food safety, monitoring, soil mapping, healthcare, territorial intelligence, local food production, greenhouse gas emissions, renewable energy sources, integrated development, sustainability strategies, “smart” bio-territories, replete with case studies. This book aims to provide the perspective of the diverse problems in global sustainability, and the many disciplines that could work together in achieving it. The workshop itself led to the signing of international agreements for the protection and enhancement of endangered species in the area of North Africa.

Ceramic Materials: Science and Engineering is an up-to-date treatment of ceramic science, engineering, and applications in a single, integrated text. Building on a foundation of crystal structures, phase equilibria, defects and the mechanical properties of ceramic materials, students are shown how these materials are processed for a broad diversity of applications in today's society. Concepts such as how and why ions move, how ceramics interact with light and magnetic fields, and how they respond to temperature changes are discussed in the context of their applications. References to the art and history of ceramics are included throughout the text. The text concludes with discussions of ceramics in biology and medicine, ceramics as gemstones and the role of ceramics in the interplay between industry and the environment. Extensively illustrated, the text also includes questions for the student and recommendations for additional reading. KEY FEATURES: Combines the treatment of bioceramics, furnaces, glass, optics, pores, gemstones, and point defects in a single text Provides abundant examples and illustrations relating theory to practical applications Suitable for advanced undergraduate and graduate teaching and as a reference for researchers in materials science Written by established and successful teachers and authors with experience in both research and industry

The current book contains twenty-two chapters and is divided into three sections. Section I consists of nine chapters which discuss synthesis through innovative as well as modified conventional techniques of certain advanced ceramics (e.g. target materials, high strength porous ceramics, optical and thermo-luminescent ceramics, ceramic powders and fibers) and their characterization using a combination of well known and advanced techniques. Section II is also composed of nine chapters, which are dealing with the aqueous processing of nitride ceramics, the shape and size optimization of ceramic components through design methodologies and manufacturing technologies, the sinterability and properties of ZnNb oxide ceramics, the grinding optimization, the redox behaviour of ceria based and related materials, the alloy reinforcement by ceramic particles addition, the sintering study through dihedral surface angle using AFM and the surface modification and properties induced by a laser beam in pressings of ceramic powders.
