Abstract： Transformative energy technologies will provide strong strategic support to the realization of peaking carbon dioxide emissions before 2030, and achieving net zero carbon emissions before 2060. Reducing the dependence on fossil fuels by saving energy and reducing emissions from the source is essential to achieve the double-carbon target as soon as possible. Songshan Lake Materials Laboratory is working on key materials to develop solar-battery power systems and electrification of transportation energy to return coal, oil, and natural gas from fuels to materials. This study focuses on introducing the research team of its New Energy Materials and Devices R&D Center with the whole chain innovation mode from research to technology transfer/transformation. Example works of new materials for High Efficiency Crystalline Silicon Solar Cells Group, Li-ion Battery Materials Group, Flexible & Zinc Battery Group are introduced. To get through “the last mile” of technology transformation, research projects and pilot lines have been set up to make new energy materials and devices into products in the past three years, and work together with industrial partners in an innovative workshop cluster model. It is suggested to make overall planning, provide stable support to the research and development, and create a cluster development model with R&D center-innovative workshops#2;industrial parks.

Abstract： The rapid development of the information society puts forward an ever-increasing urgent need for information storage, processing, and transmission capabilities. With the ending of Moore's Law, the semiconductor industry urgently needs to find new solutions. Low#2;dimensional materials are considered to be a new breakthrough in the semiconductor industry in the post-Moore era, because of the size characteristics of atomic-level thickness, the structural advantage of no dangling bonds on the surface, and the sensitivity to electrical and optical control methods caused by a large specific surface area. Songshan Lake Materials Laboratory has introduced a group of top scientists and established a low-dimensional materials team. The research of the team, based on basic science and guided by engineering applications, focuses on tackling key issues. The goal is to achieve world-class influential scientific research results, and to deploy China low-dimensional materials industry.

Abstract： Integrated photonics are fast-developing research field for next generation information technology. Current silicon photonic integrated chips strongly benefit from low-cost and high-density integration properties of existing CMOS technology. But limited by the physical properties of silicon, it is not a perfect material for different types of optoelectronic devices, such as laser sources, modulators, and infrared detectors. Therefore, heterogeneous integration is proposed by combining the advantages of CMOS process and superior opto-electric properties of heterogenous material systems, that can be an essential step towards next generation integrated optoelectronic chips. Here, this paper introduces the rapid progress of integrated photonics nationally and worldwide, while discusses the potential directions and opportunities in this field.

Abstract： The development of metallic materials is closely correlated to the civilization of human being. Amorphous alloys with long-range disordered atomic microstructure, unique physical and mechanical properties, are advanced and novel metallic materials which have diverse industrial applications. Recently, the scientific research, new system development, and industry applications of the structural disordered alloys such as amorphous alloys and high entropy alloy are fast developing, and have significant influence on fields such as the desgin and development of metallic materials, structural materials, green materials, magnetic materials, catalytic materials, and information materials. In this article, we review the history, the development trends, the fundamental scientific issues, applications and basic research chances and challenges of amorphous and related structural disordered alloys. The role of Chinese scientists in the development of the disordered alloys is evaluated and introduced. We propose the corresponding implication and suggestions on the future development and applications of the fast#2;moving field and the advanced metallic materials in China.

Abstract： The advanced material industry is a basic and strategic industry of the national economy, as well as the key area of global competition in technology industry. Under the dual-cycle development pattern, propelling the cluster development of advanced material industry has become a key to raise the level of the advanced material industry development. This article described the spatial distribution of the advanced material industry cluster in China, analyzed the characteristics and development stage of the advanced material industrial cluster, and compared the gap between the advanced material industry cluster in China and the world-class advanced manufacturing industry cluster. In addition, suggestions were put forward for accelerating the high-quality development of the advanced material industry cluster in China under the new situation.

Abstract： New materials are considered as the foreguide and the base of the revolution of advanced technology. Its development and trend of new materials greatly influences the human life and society development. Nowadays, the risk of climate change is increasing day by day, the pressure of manufacturing update of new technology revolution is bigger than ever, the competition and the friction between countries become more and more intense, and the iteration of advanced materials turns to a rigid demand. In this work, we analyze and predict the development tread of material from the aspects of climate change, manufacturing update, national security, and materials genome initiative.
