Bio-based polyester materials, which are renewable, biodegradable, and biocompatible, meet the environmental protection concept of green and low-carbon development, and they have received more attention and made significant progress in the field of fundamental research and industrialization. This review analyzed the advantages of bio-based polyester materials, the development status of the bio-based polyester industry in China and abroad, the future trend of the bio-based polyester industry, and policy suggestions for the development of the bio-based polyester industry. It was intended to provide a reference for researchers and insiders engaged in the bio-based polyester industry and promote the further development and promotion of bio-based polyester materials.

Under the dual impetus of global carbon neutrality goals and energy security strategies, nanowire energy storage materials and devices have emerged as a pivotal engine driving the development of next-generation high-performance energy storage technologies, owing to their unique structural advantages and performance scalability. This article systematically summarized the groundbreaking advancements of nanowire materials in fields such as energy storage batteries and flexible and micro-nano energy storage devices and highlighted their critical value in strategic scenarios including rapid response in new power systems, autonomous energy supply for flexible electronics, and high energy density requirements in low-altitude economies. Furthermore, to address challenges such as the lack of multi-physics field coupling regulation mechanisms, unclear multi-particle collaborative transport mechanisms, and contradictions in cross-scale functional integration, the article proposed the establishment of a synergistic innovation system encompassing “fundamental theory, device engineering, and industrial ecology.” By leveraging multi-field coupled in-situ characterization, external field synergistic manufacturing, and data-driven research paradigms, the article aims to facilitate the transition of technology from laboratory to industrialization, thereby providing strategic support for securing a leading position in global energy storage technology.

Under the backdrop of reforms in the operational mechanisms of oil and natural gas pipeline networks and the objectives of “carbon peak and carbon neutrality”, the operational conditions of pipelines have become more variable and the transportation mediums more diverse, expanding the boundaries of pipeline transportation. However, this also introduces more operational risks and safety hazards, urgently requiring the resolution of scientific issues and key technologies for flexible transportation through complex networks. This article analyzes the essence of flexible pipeline transportation, identifies the challenges faced by different types of pipeline networks, and on this basis, summarizes the current development status and technical difficulties of key technologies in flexible pipeline transportation. Finally, from six key directions—open markets, safety protection, digital twins, transportation optimization, multi-network integration, and innovative applications—suggestions are proposed for the development of flexible pipeline transportation in China. These recommendations aim to provide more accurate guidance for energy planning and management, thereby helping to construct a low-carbon, flexible, safe, and efficient modern comprehensive energy system.
