Advanced green energy nanomaterials in the applied science fields have received increasing attention because of their unique physical and chemical properties. Their dominant roles are established in our science and society. This special issue aims to identify the current status and anticipate future directions in this emerging field via fusions of civil engineering, environmental science, chemistry, materials science, and antiecotoxic technologies. With the unique structures and novel properties of the nanomaterials, the applications cover a wide range of key components or products, such as light-emitting diodes (LED), solar cell devices, nanocomposites, optical materials, functional materials, and other related advanced nanomaterials.

The major goal of this special issue is to provide a consolidated forum for researchers to demonstrate their innovative works related to nanomaterials synthesis, processing, characterization, and applications. We invite investigators to contribute original research articles as well as review articles that represent a source of stimulation and advance to the science of nitride, oxides, and green energy-based materials.

Potential topics include, but are not limited to:

• Synthesis and self-assembly of nanomaterials for green energies 
• Novel growth technique and characterization of III-nitride materials for optoelectronic applications
• Growth and applications of oxide materials for optoelectronic applications, for example, transparent conducting oxide (TCO) and UV-transparent contact layer (TCL)
• Nanoscale characterization of nanomaterials
• Nanophotonics and nanoelectronics 
• Novel properties of nanomaterials
