Abstract

We are glad to introduce you that the 2021 International Conference on Energy Engineering, New Energy Materials and Devices (NEMD 2021) was carried out in the form of virtual conference on January 15-17, 2021. Due to the impact of COVID-19 and travel restrictions, NEMD 2021 was held via online collaboration tool, Zoom, which is different from the traditional way. NEMD 2021 aimed to provide a flexible platform for experts and scholars in the field of energy engineering, new energy materials and devices to disseminate the latest research achievements and advanced technologies, as well as to promote the cooperation between each other. Firstly, we were honored to invite Prof. Hong Qi, Harbin Institute of Technology, China as conference chair and keynote speaker. Prof.Qi is the director of Department of refrigeration and thermal control in Harbin Institute of Technology, and deputy director of Key Laboratory of aerospace thermophysics, Ministry of industry and information technology. Main research fields: thermal radiation transmission and coupled heat transfer, inverse problem and intelligent optimization algorithm, microalgae new energy utilization, near infrared optical imaging, high temperature flame temperature reconstruction, etc. During the conference, the conference model was divided into four sessions, including keynote speeches, invited speeches, oral presentations and online Q&A discussion. In the keynote speeches session, keynote speakers were each allocated 30-40 minutes to hold their speeches. We were honored to invite four distinguished experts as keynote speakers to present their insightful speeches. Prof. Hong Qi from Harbin Institute of Technology, China, made a speech about Integrated technology of biological photothermal precise diagnosis and treatment based on multifunctional nanoparticles. Prof. Roger Ruan from University of Minnesota, USA, shared his study on Catalytic microwave assisted pyrolysis of solid waste for fuels, energy and chemicals production. Prof. Gangtao Liang from Dalian University of Technology, China and his speech title is: Microscale Heat Dissipation Surface for High-Heat-Flux Cooling. Prof. Jun He from University of Nottingham Ningbo China, China, held a speech on the topic of Cost-effective Non-precious Metal Catalysts for Low-temperature Formaldehyde Decomposition. In the invited speeches session, invited speakers were each allocated 20-30 minutes to hold their speeches. We were pleased to invite two excellent experts as keynote speakers to present their insightful speeches. Prof. Wenbin Yang from Southwest University of Science and Technology, China, his speech is about Design and preparation of phase change microcapsules and nanocapsules. Prof. Xijun Hu from The Hong Kong University of Science and Technology, China, made a speech about Advanced Catalysts Design Towards Overall Water Splitting. In the oral presentation’s session, some scholars were given about 10-15 minutes to perform their oral presentations one by one. We were honored to invite Prof. Roger Ruan from University of Minnesota, USA as Session Chair of the Oral Presentation’s Session. There were fifteen scholars to present their speech on the topic of energy and environmental engineering, etc. In the Q&A session, all participants were invited to join in academic groups to discuss and explore the academic issues after the presentations. The discussion session will last 40 minutes. The proceedings collected the latest research and results in the field of energy and environmental engineering. The topic of this collection is related to energy engineering, electric power engineering, energy conservation and emission reduction and environmental engineering and so on. All manuscripts published in the proceeding have been through rigorous review and process to meet the requirements of International publication standard. Finally, we would like to express our sincere gratitude to the Chairman, the distinguished keynote speakers, as well as all the participants. Because of your enthusiastic participation, the conference was successfully held as planned. Thanks to the information technology, the online conference made it easier for more people join in our conference. We had around 80 attendees this time, and we are expecting more and more experts and scholars from all over the world to join this international event next year. We also want to thank the publisher for publishing the proceedings. We are grateful to all those who have contributed to the success of NEMD 2021. We hope that all participants and other interested readers benefit scientifically from the proceedings. The Organizing Committee of NEMD 2021 List of Organizing Committees are available in this pdf.
