Metamaterial -- from engineering materials to engineering materials

As one of the frontier directions in the field of materials science, Metamaterial have experienced vigorous development in the past 20 years. Today, Metamaterial have expanded to include Electromagnetism, a large class of artificial material systems with extraordinary and high performance covering many fields such as optics, mechanics, heat and acoustics.

Professor John Pendry of Imperial College London, an academician of the CAE Member, and Professor Zhou Ji of Tsinghua University published the message "Metamaterial - From Engineered Materials to Engineered Materials", pointing out that the focus of Metamaterial research has gradually shifted from the initial new mechanism, new phenomenon and new structure to new features and new functions for practical applications, providing new solutions for solving many challenges in engineering technology.

Development opportunities and directions for intelligent manufacturing of high-end new materials

High end new materials are core materials supporting high-end equipment and Megaproject, including advanced basic materials such as high-performance aluminum alloys, magnesium alloys, titanium alloys, key strategic materials such as superalloys, and cutting-edge new materials such as additive manufacturing metal materials. They play a pivotal role in strategic fields such as aviation, aerospace, energy, transportation, electronic information, weapons and equipment.

The research team of Ding Wenjiang, Wang Huaming and Xie Jianxin, academicians of the Chinese Academy of Engineering, published the Development Opportunities and Direction of Intelligent Manufacturing of High end New Materials. The article points out that the development of intelligent manufacturing is the main direction of innovation and upgrading of China's manufacturing industry. High end new materials are the core materials supporting the needs of high-end equipment and Megaproject. Promoting the close integration of intelligent manufacturing and high-end new material manufacturing is of great significance to improving the manufacturing capacity of high-end new materials and meeting the needs of major equipment for high-end new materials.

Taking deep emission reduction of nitrogen oxides as a starting point, promoting collaborative control of fine particulate matter and ozone

In recent years, China's air quality has significantly improved, but heavy haze pollution still occurs in autumn and winter, and ozone (O3) pollution is prominent in summer. The prevention and control of air pollution still faces serious challenges, and it is necessary to strengthen the collaborative control of PM2.5 and O3. Nitrogen oxides (NOx) mainly come from fixed combustion sources and emissions from motor vehicle internal combustion engines. They are common precursors of PM2.5 and O3, and have great emission reduction potential. They are also highly consistent with China's carbon peaking and emission reduction goals.

Academician He Hong of the Chinese Academy of Engineering and other research teams published the article "Promoting the collaborative control of fine particles and ozone with the deep emission reduction of nitrogen oxides as a starting point", analyzed the effectiveness of the deep emission reduction of nitrogen oxides in the collaborative control of PM2.5 and O3, and pointed out that nitrogen oxides are the key precursor with the highest control potential in China at present. On this basis, the article will accelerate the research and development of efficient NOx emission control technologies in the non electric industry; Establish ultra-low emission limits for key industries, strengthen evaluation and supervision; Policy recommendations for deep NOx reduction have been put forward in promoting the research and development of key technologies for diesel engine cleaning, strengthening joint control of vehicle and oil pipelines, and other aspects.

Experience Mode and Promotion Strategy of Ecological Civilization Construction in the Pearl River Delta

Since the 18th National Congress of the Communist Party of China, China has vigorously promoted the construction of ecological civilization, and achieved historic achievements in ecological environment protection and improvement. Economically developed regions play a leading and exemplary role in the national ecological civilization construction. Studying the experience of coordinated promotion of high-level ecological environment protection and high-quality economic development in developed regions, summarizing the strategies for ecological civilization construction in developed regions, and establishing a "benchmark" for ecological priority and green development is of great significance for deepening the construction of a beautiful China.

The research team of Academician Wang Jinnan of the Chinese Academy of Engineering published the article Experience Mode and Promotion Strategy of Ecological Civilization Construction in the the Pearl River Delta Region in the 6th issue of the journal of the Chinese Academy of Engineering in 2022. Taking the construction of ecological civilization in the the Pearl River Delta (PRD) as an example, this paper systematically combs the achievements in ecological space pattern, ecological environment quality, ecological civilization system, and coordinated development of economic environment, and summarizes and refines the innovative model of ecological civilization construction; On the basis of in-depth analysis of the challenges faced by regional ecological civilization construction, targeted development goals and paths have been proposed, in order to provide basic reference for the ecological civilization construction in economically developed areas of China. The article suggests improving the level of territorial space protection and restoration, promoting the Pearl River Delta region to take the lead in achieving peak carbon emissions, leading green, low-carbon, and high-quality development through technological innovation, promoting blue skies, clear waters, and sustainable improvement of the environment, creating a new trend of beautiful, livable, and ecological civilization, in order to build an innovative highland for ecological civilization system.
