Recent Advances in Durability Improvement and Low-Carbon Strategy of Engineering Materials and Structures


Book Description

Global warming, caused by a significant increase in the concentration of greenhouse gases (GHGs) such as CO2, has become a concern all over the world. The whole process carbon emissions of the civil engineering industry account for nearly 40% of global energy and process-related CO2 emissions, more than half of which come from the process of producing, using, constructing and dismantling in civil engineering materials and structures, resulting in the embodied carbon emissions. With the acceleration of global warming, warmer and uncertain climates will make engineering materials and structures subject to more severe environmental conditions. A series of durability issues will occur more frequently, such as the significant variations of humidity in air, the chloride-induced corrosion caused by the severe chloride ingress, concrete cracking caused by the expansion of rusts, and more severe carbonation of concrete structures due to the increase in CO2 concentration. The adoption of positive measures to address climate change has become a global consensus, as global warming has led to serious threats and challenges to the survival and development of humankind.







Low-carbon Supercapacitors


Book Description

Supercapacitors can both hold large amounts of energy and charge up almost instantly. They have higher energy densities, higher efficiencies and longer lifetimes so can be used in a wide range of energy harvesting and storage systems including portable power and grid applications. Despite offering key performance advantages, many device components pose significant environmental hazards, often containing fluorine, sulfur and cyanide groups which are harmful when discarded. In recent years, there has been increasing research into more sustainable electrode materials for supercapacitor applications. In this book, readers are introduced to the extensive and ongoing research on the rationalization of low-carbon supercapacitor materials, their structures at varying scales and dimensions, the development of effective and low-cost synthesis techniques, design and architecture of green materials, as well as clarification of their electrochemical performance. It is an ideal book for researchers and industry professionals at the energy–environment nexus, searching for new advancements in supercapacitor science and technologies.




Energy Absorption of Structures and Materials


Book Description

This important study focuses on the way in which structures and materials can be best designed to absorb kinetic energy in a controllable and predictable manner. Understanding of energy absorption of structures and materials is important in calculating the damage to structures caused by accidental collision, assessing the residual strength of structures after initial damage and in designing packaging to protect its contents in the event of impact. Whilst a great deal of recent research has taken place into the energy absorption behaviour of structures and materials and significant progress has been made, this knowledge is diffuse and widely scattered. This book offers a synthesis of the most recent developments and forms a detailed and comprehensive view of the area. It is an essential reference for all engineers concerned with materials engineering in relation to the theory of plasticity, structural mechanics and impact dynamics. - Important new study of energy absorption of engineering structures and materials - Shows how they can be designed to withstand sudden loading in a safe, controllable and predictable way - Illuminating case studies back up the theoretical analysis

Novel Non-Precious Metal Electrocatalysts for Oxygen Electrode Reactions


Book Description

Research on alternative energy harvesting technologies, conversion and storage systems with high efficiency, cost-effective and environmentally friendly systems, such as fuel cells, rechargeable metal-air batteries, unitized regenerative cells, and water electrolyzers has been stimulated by the global demand on energy. The conversion between oxygen and water plays a key step in the development of oxygen electrodes: oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), processes activated mostly by precious metals, like platinum. Their scarcity, their prohibitive cost, and declining activity greatly hamper large-scale applications. This issue reports on novel non-precious metal electrocatalysts based on the innovative design in chemical compositions, structure, and morphology, and supports for the oxygen reaction.
