The ICKEM 2022 was held virtually on March 18-20, 2022. The rapid development of modern technology needs the support of many new materials. Since the third wave of science and technology swept the world, new materials, together with information energy, have been called the three-generation pillars of modern science and technology. Material science has developed into an interdisciplinary and comprehensive discipline. The main goal and feature of ICKEM are to bring scientists, engineers, and industry researchers together to exchange and share their experiences and research results, and discuss the practical challenges encountered and the solutions adopted. The articles collected from ICKEM 2022 introduce readers to the research results and engineering solutions in the area of materials for application in machinery, environmental engineering, biomedicine, electronics and electrical engineering. This edition will be helpful to a wide range of engineers and academics for many branches of modern production.
