Nanoscienceintegrates engineering, science, and technology to analyze matter and processes at the nanoscale. By performing at the atomic level, scientists can improve the physical, chemical, biological, and optical properties of matter. The unique propertiesofnanomaterialsare attributed to quantum effects, large area, and self-assembly. It aims to enhance emergingnanotechnology. Nanotechnologyhas an immediate impact on all aspects of engineering as new products are discovered and marketed. Some of the areas covered will be the most effectivenanomaterials, and the impact ofnanotechnologyon energy systems, including nanobiotechnology, nanomedicine, and nanotechnology suitable for space systems. Some important developments in thermal systems, as well as future forecasts for nanotechnology, may provide the latest applications.
