Concluding Remarks

Abstract

In this volume of Energy Materials, energetic applications of a wide variety of conventional and novel materials are introduced and discussed in detail. Energetic applications of these materials are very diverse, but not even limited to energy extraction, production, conversion, and storage. In the entire volume, 3S (source-system-service) approach is followed. The materials covered in this volume is in a wide range starting from chemical fuels (such as ammonia) to carbon-based materials, boron, thin films, PV materials, porous materials, magnetic materials, semiconductors, electrolytic materials,. refrigerants, catalysts, photoactive materials, solid oxides, batteries, pyroelectric materials, insulation materials, hydrophobic materials, dust repellent materials, CO<inf>2</inf> capturing materials, novel building materials, desulfurization materials, and materials recycling. Some of these materials have been used extensively for a long period of time for many energetic applications (such as fossil fuel processing), while some of these materials have quite novel applications (such as nanomaterials). As the global energy challenges get more complicated, it is surely expected that advanced and complex novel materials are to be needed to tackle these issues. © 2018 Elsevier B.V., All rights reserved.
