Preface

The 2019 3rd International Conference on Energy Material, Chemical Engineering and Mining Engineering (EMCEME 2019), as an international forum aiming at presenting and exchanging technological advances and research results in the broad fields of energy material, chemical engineering, resource exploration and mining engineering, was held during December 28-29, 2019 in Qingdao, China. EMCEME 2019 brought together leading researchers, engineers and scientists in the domain of interest from around the world. During the conference, the participants shared their research results and discussed the development and research applications in these fields. Accepted papers after proper registration and presentation will be published into conference proceedings. Eventually, the total number of submitted papers, whose topics included Functional Materials and Chemical Engineering, Energy Utilization and Smart Grids, Resource Exploration and Mining Engineering, Sustainability and Environmental Protection, was more than 400, and among which less than 360 were accepted. Finally, we would like to express our gratitude to the reviewers of these manuscripts, who provided constructive criticism and stimulated comments and suggestions to the authors. We are extremely grateful as organizers, technical program committee and editors and extend our most sincere thanks to all the authors for their excellent contribution and work. Our sincere gratitude also goes to the IOP Publishing editors and managers for their helpful cooperation during the preparation of the proceeding.
