Globally, lithium ion batteries (LIBs) are leaders in the energy storage sector but there are concerns regarding load leveling of renewable energy sources as well as smart grids and limited availability of lithium resources resulting in cost increase. Therefore, sodium ion batteries (SIBs) are being researched as next-generation alternatives to LIBs due to their similar sustainability and electrochemistry. This book mainly focuses on the current research on electrode materials and proposes future directions for SIBs to meet the current challenges associated with the full cell aspect. Further, it provide insights into scientific and practical issues in the development of SIBs.

Connie Kelly Tang and Lei Zhang have provided a holistic coverage of the entire surface transportation project and program development process from the beginning of planning though environmental approval, design, right-of way acquisition, construction to operations and maintenance.— Neil Pedersen, Executive Director, Transportation Research Board, National Academies of Sciences, Engineering, and Medicine, Washington, DC

Transportation program and project development is complex. The process spans over planning, programming, environment, design, right of way, construction, operations, and maintenance. Professionals from civil engineering, planning, social and environmental sciences, business and project management, and data science, work together in a relay team to transform an idea into a highway, a transit hub, an airport or a water facility. It is challenging for any one person to master all the knowledge and skills needed to perform every relevant task. However, it is critical for all involved to understand how this relay works and how the societal, environmental, governmental, and regulatory contexts influence the process and the technical solution. Professionals who understand the process and see the big picture are those who rise to the top as leaders.

Transportation Project and Program Development provides holistic coverage on the technical subject matter, processes and procedures, and policy and guidance associated with transportation project and program development, which can help professionals become program leaders. For each phase of the process, key products delivered, processes used, governing principles, foundations of applicable science and engineering, technologies deployed, and knowledge required are discussed. While all coverages reflect the practices of the United States, the logic, principles, science, and engineering are applicable to all countries of the world. The book can also serve as an introductory textbook for undergraduate students and as a textbook or reference for a graduate-level course in civil engineering, transportation engineering, planning, and project management.

This book takes an in-depth look at Covid-19-generated societal trends and develops scenarios for possible future directions of urban lifestyles.

Drawing on examples from Brazil, China, and Israel, and with a particular focus on cities, this book explores the short and long-term changes in individual consumers and citizen behavior as a result of the Covid-19 pandemic. On the basis of extensive market and opinion research data, aggregate data, observational evidence, and news reports, the authors provide a detailed account of the transformations that have occurred as a result of a triple shock of public health emergency, economic shutdown, and social isolation. They also examine which of these behavioral changes are likely to become permanent and consider whether this may ultimately promote or restrain sustainable lifestyle choices.

Innovative and timely, this book will be of great interest to students, scholars, and professionals researching and working in the areas of sustainable consumption, urban and land use planning, and public health.
