Overview

In the past decades, nanoscience and nanotechnology has been making significant progress, and the effect of nanoscience and nanotechnology on every field has been acknowledged in the world. Therefore, in the 21st century, their strategic position has already been established. The study of nanomaterials and nanostructures is one field with the earliest starting that obtained rich achievements in nanoscience and nanotechnology. Nanomaterials and nanostructures play a very important supporting role for applications of nanoscience and nanotechnology in the field of fabrication, such as information and techniques, energy sources, environments, health and medical treatments. All countries place the study of nanomaterials and nanostructures in a very important position. While the United States arranges the development of the front fields of nanoscience and nanotechnology, such as nanoelectronic technologies and devices, nano- and micro-fabrication techniques, nanobiotechnology nanomedicines and diagnosis techniques, nanoenvironmental monitoring and treatment techniques, the continuation of the in depth study of nanomaterials and nanostructures is placed in an extremely important position. In the investment for the study of nanoscience and nanotechnology, the investment for nanomaterials and nanostructures occupies 49%. This sufficiently indicates the guiding role and the importance of the study of nanomaterials and nanostructures. Now, the motivational power of the study of nanomaterials and nanostructures are mainly national strategy requirements and enhancements of the national competitive ability in the high science and technology field. In addition, the in depth study of nanomaterials and nanostructures is an important source for producing new principles, new techniques and new methods, and potentially...
