This is the first volume (Part A) in the series of books covering practical aspects of synthesis and characterization of various categories of nanomaterials taking into consideration the most up to date research publications. The aim of the book series is to provide students and researchers practical information such as synthetic procedures, characterization protocols and mechanistic insights to enable them to either reproduce well established methods or plan for new syntheses of size and shape controlled nanomaterials based on both batch and continuous flow reactions. The first Volume (Part A) focuses on metallic nanomaterials.

This book constitutes the proceedings of the 8th CCF Conference on Big Data, BigData 2020, held in Chongqing, China, in October 2020. The 16 full papers presented in this volume were carefully reviewed and selected from 65 submissions. They present recent research on theoretical and technical aspects on big data, as well as on digital economy demands in big data applications.
