Hydrogen electrical vehicles are an essential component of the “Green New Deal” and this book covers cutting-edge technologies designed for fuel-cell-powered cars. Fuel cells use hydrogen directly in most types of vehicles—from passenger cars to trains—without some of the disadvantages of batteries such as low energy density, high initial costs, and a slow charge. Therefore, the number of hydrogen filling stations required for fuel cells, about one-tenth of the number of fast-charging stations, can meet the same needs as batteries. Additionally, hydrogen charging is at least three times faster. Therefore, it is essential to emphasize that hydrogen-powered transportation is still the most reasonable way to reduce emissions. As part of our “Advances in Hydrogen Productıon and Storage” series, this volume covers the cutting-edge technologies used in fuel cell-powered cars. Additionally, it highlights the research efforts presented in the literature while adding a valuable component to the area. It also discusses basic as well as advanced engineering details for both scientists and engineers in academia and industry. | |

Metal-Air Batteries: Principles, Progress, and Perspectives covers the entire spectrum of metal-air batteries, their working principles, recent advancement, and future perspectives. Leading international researchers address materials design, electrochemistry, and architectural aspects. The fundamentals of metal-air materials for cathode and anode, their synthetic approaches, chemistries to modify their properties to provide high energy and power densities, along with long life and stable electrochemical characteristics are detailed. There is a need to develop high-performance and sustainable energy devices which could meet the future demand for energy on the consumer as well as industrial scale. Most of the current energy needs are fulflled by fossil fuels which are damaging our environment. Global warming and air pollution are some of the major issues caused by the use of excessive fossil fuels, and therefore researchers need to fnd some alternatives. Approaches such as the use of hybrid electric vehicles and electric vehicles are a few solutions to these problems. Adaptation of electric vehicles has some challenges such as low performance of the batteries, their life, cost, and range per charge. Metal-air batteries offer higher energy density compared to many other battery technologies. However, such technology has many challenges such as the use of advanced electrochemical materials, porous cathode, electrolytes, device architecture, etc. | |

 Название: Friction Stir Welding and Processing XII
Автор: Yuri Hovanski, Yutaka Sato, Piyush Upadhyay
Издательство: Springer
Год: 2023

This collection presents fundamentals and the current status of friction stir welding (FSW) and solid-state friction stir processing of materials and provides researchers and engineers with an opportunity to review the current status of the friction stir related processes and discuss the future possibilities. Contributions cover various aspects of friction stir welding and processing including their derivative technologies. Aerospace flight panels must provide high strength with low mass. For aluminum panels, it is common practice to begin with a wrought plate and remove the majority of the material to attain the desired structure, comprising a thinner plate with the desired pattern of reinforcement ribs. As an alternative, this study implements hybrid manufacturing, where aluminum is first deposited on a baseplate only at the rib locations using additive friction stir deposition (AFSD). | |

Исследования в области техногенного засорения космоса — в настоящее время одно из наиболее актуальных и стремительно развивающихся научных направлений. Злободневность проблемы космического мусора обусловлена усиливающимся засорением околоземного пространства, снижением под его воздействием качества функционирования космических аппаратов и выходом их из строя, столкновениями и взрывами космических объектов. | |
