Abstract

The 9th International Conference on Advanced Manufacturing Technology and Materials Science (AMTMS 2021) was planned to be held on November 19-21, 2021 in Beijing, China. Considering the COVID-19 pandemic, the AMTMS 2021 conference was held virtually as agencies around the world are now issuing restrictions on travel, gatherings, and meetings to limit and slow the spread of this pandemic. The health and safety of our participants and members of our research community is of top priority to the Organizing Committee. Therefore, the AMTMS 2021 conference was held online through Zoom software.AMTMS 2021 is being organized by Beihang University to provide an opportunity to research scholars, delegates, and students to interact and share their experience and knowledge in Advanced Manufacturing Technology and Materials. We sincerely welcome all scientists, scholars, students, industrialists to attend and explore their knowledge in the field of Functional Materials and Applied Technologies. We strongly believe that AMTMS 2021 was a remarkable event which can bring together professors, researchers, and students in the field of functional materials and applied technologies making the conference a perfect platform to share experience, foster collaborations across industry and academia, and evaluate emerging technologies across the globe. More than 150 participants attended the online conference, they were from China, Canada, Malaysia and more.During the conference, the conference model was divided into three sessions, including oral presentations, keynote speeches, and online Q&A discussion. In the first part, some scholars, whose submissions were selected as the excellent papers, were given about 5-10 minutes to perform their oral presentations one by one. Then in the second and third part, keynote speakers were each allocated 30-45 minutes to hold their speeches. In the keynote speeches part, we invited four professors as our keynote speakers. Prof. Lu Li, National University of Singapore. Dr. Lu’s research interests include nanostructured materials, and functional thin films such as all-solid-state micro batteries and ferroelectric thin films. And then we had Prof. Sung-Hoon Ahn (CIRP Fellow), Seoul National University, South Korea. Dr. Ahn’s research interests include soft robotics, smart/composite materials, micro/nano fabrications, 3D/4D printing, smart factory, green manufacturing, renewable energy, smart grid, and appropriate technology. Prof. Lihui Lang, our third keynote speakers, from Beihang University, China. He mainly focuses on automotive, aircraft and aerospace fields. And then we invited Prof. Jiangfeng Ni, from Soochow University, China as our finale keynote speaker. At present Dr. Ni is leading a team working on various types of energy storage systems including rechargeable batteries, supercapacitors, with a focus on fundamental physics, chemistry, and materials in these devices. Their insightful speeches had triggered heated discussion in the third session of the conference. Every participant praised this conference for disseminating useful and insightful knowledge.The proceedings are a compilation of the accepted papers and represent an interesting outcome of the conference. Topics include but are not limited to the following areas: Materials Processing Technology and Materials Science, Manufacturing Technology and Systems and Other related topics. All the papers have been through rigorous review and process to meet the requirements of International publication standard.This year, we have all worked and lived with the daily threat of Covid-19, the need for social distancing and relative isolation has impacted upon the familiar and fundamental nature of conferences. Regardless, such interactions are the lifeblood of our respective communities, and so we made the decision to proceed with the Workshop, bring participants together from around the world through a digital platform. We would like to acknowledge all of those who supported AMTMS 2021. The help and contribution of each individual and institution was instrumental in the success of the conference. We would like to thank the organizing committee for its valuable inputs in shaping the conference program and reviewing the submitted papers.The Committee of AMTMS 2021List of Committee member are available in this pdf.
