About this collection
As modern society’s demand for energy continues to grow, the development of nanomaterials for reducing energy consumption and generating and storing energy is becoming increasingly important. With advances in synthesis methods and theoretical simulations of nanomaterials, attention has turned to how nanomaterials can be rationally designed and synthesized, transformed into energy devices, and ultimately, how devices (such as solar cells, batteries, fuel cells, supercapacitors, light-emitting diodes, photodetectors etc.) can be integrated into systems to tackle real global challenges.
Guest edited by Professor Guohua Jia (Curtin University, Australia), Professor Hongxia Wang (Queensland University of Technology, Australia), Professor Xuyong Yang (Shanghai University, China), Professor Lina Quan (Virginia Tech, USA) and Professor Yun Liu (Australian National University, Australia), this Journal of Materials Chemistry A, Journal of Materials Chemistry C and Nanoscale collection will capture the cutting-edge innovations in nanomaterials synthesis, simulation, device fabrication, and system integration that are driving this field forward.
