This book gathers selected papers from the 28th International Cryogenic Engineering Conference and International Cryogenic Materials Conference 2022 (ICEC28-ICMC 2022), held virtually in Hangzhou, China on 25-29 April 2022, due to COVID-19 pandemic. Highlighting the latest findings on cryogenic engineering and cryogenic materials, it covers topics including: large-scale cryogenic components, processes and systems for refrigeration, separation, and liquefaction of cryogenic fluids, small-scale cryocoolers, cryogenic space applications, thermal insulation, thermal-physical properties of cryogenic fluids and materials, superconducting materials, devices, systems and applications, etc. The book offers valuable information and insights for academic researchers, engineers in the industry, and operators in the cryogenic field.

Ultra-high-pressure technology has been taking the sterilization and inactivation of agricultural products and food as core research and application fields since its birth. This book first outlines the basic principles of ultra-high pressure and then introduces non-traditional applications of the ultra-high-pressure technology in agricultural products such as Baijiu (the Chinese liquor), brown rice, and wood. These applications were discovered by the author, as well as the representative quality improvements of treatment objects brought by these applications. Finally, the author puts forward his own ideas on the non-traditional application trend of ultra-high-pressure technology in the future. This book aims to broaden the thinking for the application and research of ultra-high-pressure technology in agricultural product processing and propose specific ideas for future research and application in this field on the basis of the author¿s current research.

Convergence in crossover service explores the crossover phenomenon, crossover services and the convergence issues that arise in typical crossover scenarios. Unlike traditional service integration, crossover services need to realize multidimensional convergence of pattern, design, run-time environment, quality, and value.This book creatively proposes a framework of crossover service pattern modeling, simulation, evaluation, and convergence to achieve quantitative calculation and analysis of crossover service patterns. Also, this book provides a requirements convergence modeling and analysis framework to support crossover services requirements analysis and design. In the meantime, authors develop a new crossover service network architecture to achieve efficient governance of large-scale crossover services and construct an evaluation and optimization system for service quality and value. In the case of the rural Taobao scenario, the theory and engineering methods presented in this book can provide better solutions for crossover convergence.This book is of great interest to researchers and academics wishing to see what crossover services are, how they are implemented, and what benefits they bring.

This book is in the field of Engineering Thermophysics. It first introduces the authors¿ academic thoughts of photo-thermal energy cascade conversion in the fuel combustion. Afterward, a series of thermal radiation theories and models have been developed based on the aim of radiative energy utilization, including spectral radiation available energy theory, gas radiation model under complex combustion conditions, and calculation model of radiation available energy transfer in combustion medium. Based on simulation and experimental results, the radiative energy characteristics of different fuel combustion are introduced. This book develops the radiation theory of the combustion process from a new perspective, integrating theories, models, and experimental results. This book can be used as a reference for scientists, engineers, and graduate students engaged in energy environment, combustion, and thermal radiation.
