能源、材料、信息是当前科学技术发展的关键领域,材料又是其他各个领域发展不可缺少的物质基础和支撑。材料科学与技术发展得好,可以成为推动其他领域发展的强力助推器,反之就会成为制约其他领域高水平发展的瓶颈。当前材料科学发展的前沿之一是对材料尺度效应的研究。这里的尺寸效 Energy, materials and information are the key areas for the development of science and technology. Materials are indispensable material bases and support for the development of other fields. Well-developed materials science and technology can become powerful boosters to promote the development in other fields. On the contrary, they will become the bottleneck restricting the high-level development in other fields. At present, one of the forefront of material science development is the study of material scale effect. The size of the effect here
