The term 'nanobattery' can refer not only to the nanosized battery, but also to the uses of nanotechnology in a macro-sized battery for enhancing its performance and lifetime. Nanobatteries can offer many advantages over the traditional battery, including higher power density, shorter charging time, and longer shelf life. Nano-generators refer to the uses of nanosized devices and materials to convert mechanical, thermal and light-based energies into electricity. Similar to with traditional battery, in nanobatteries, the chemical energy is converted into electricity. This book addresses the fundamental design concepts and promising applications of nanobatteries and nanogenerators. Particular application areas include healthcare, biomedical, smart nanodevices and nanosensors, which may require new electric power sources, including self-powered ability and nanostructured electric power sources. In this regard, nanobatteries and nanogenerators represent the next generation of electric power. This is an important reference source for materials scientists, engineers and energy scientists, who are looking to increase their understanding of how nanotechnology is being used to create new energy storage and generation solutions.

The gradual increase of population and the consequential rise in the energy demands in recent years have led to the widespread use of fossil fuels. CO2 transformation by various processes is considered as a promising alternative technology. This book sets out the fundaments of how nanomaterials are being used for this purpose. Nanomaterials for CO2 Capture, Storage, Conversion and Utilization summarizes the research, development and innovations in the capture, storage, transformation and utilization of CO2 into useful products and raw chemicals for industry. This is achieved by using advanced processes such as CO2 reforming, bi-reforming and tri-reforming of hydrocarbons or biomass derivatives; homogeneous and heterogeneous hydrogenation; photochemical reduction; photoelectrochemical reduction; electrochemical reduction; biochemical reduction; supercritical CO2 technology; advanced catalyst synthesis for CO2 conversion; organic carbonates for polymers synthesis from CO2, and CO2 capture and sequestration. The systematic and updated reviews on the mentioned sectors, especially on the use of nanotechnology for the transformation of CO2 is scarce in the literature. Thus, the book addresses the recent knowledge gaps and potential solutions of the storage, utilization and transformation of CO2 as well as its promising applications. This is an important reference source for materials scientists, engineers and energy scientists who want to understand how nanotechnology is helping us to solve some of the world's major energy problems.
