Non-covalent interactions have gained increasing attention for the use as a driving force to fabricate various supramolecular architectures, exhibiting great potential in crystal and materials engineering and supramolecular chemistry. As...

Electronic wastes (e-wastes) recycling is one of the central frameworks of the circular economy. However, most e-wastes consist of both organic and inorganic compositions, which significantly limits their clean separation...

Greenhouse gases released from the combustion and processing of fossil-based fuels result in disastrous ramifications to modern society, and thereby, the development of alternative renewable energy sources is an inevitable tendency. However, various obstructions remain in new energy systems. The research and development of nanotechnology (such as the innovation of nanomaterials and nanoreactors) are considered one of the most encouraging approaches to improve the efficiency of clean energy systems, facilitating their implementation to satisfy the world's energy demand. In this chapter, renewable energy sources, such as solar energy, wind power, geothermal energy, and hydrogen energy, using nanotechnology will be summarized.
