The development of innovative intelligent technologies in cutting-edge fields such as aerospace, autonomous driving, unmanned aerial vehicles, robotics, artificial perception, and advanced medical applications has imposed significant demands on the high performance of ferroic smart materials. However, conventional ferroic smart materials based on Landau theory of phase transition exhibit performance limitations rooted in their fundamental physics, rendering further breakthroughs challenging. In recent years, the discovery and development of strain glass have provided new opportunities for overcoming these constraints of ferroic smart materials and achieving revolutionary performance enhancements. This review presented recent research progress in strain glass ferroic smart materials and provided forward-looking perspectives and recommendations for the future development of this novel ferroic smart material. It offered insights to maintain China’s leading position in fundamental research on ferroic smart materials and propel leapfrogging development in industrial applications.

This paper provided a concise overview of the potential biological roles of hydrogen (H₂) in the origin of life and introduced background knowledge on H₂ biogeochemical cycles and the historical development of hydrogen-based agriculture worldwide. The notable advancements achieved in hydrogen-based agriculture in China were addressed, including significant progress in pertinent scientific theories, practical implementations that demonstrate the prolongation of agricultural products’ shelf life from pre-harvest to post-harvest phases, and large-scale field trials conducted over years in multiple locations to positively improve crop yields and enhance overall product quality. By considering the ongoing efforts to minimize chemical fertilizer and pesticide usage, the rural revitalization plan, and demands for building a healthy China, this paper further outlined developmental strategies of hydrogen-based agriculture in China. These encompassed three key aspects: Suitable methods for large-scale hydrogen supply in the field, the establishment of hydrogen-based agriculture standards for matching the special animal breeding industry with the planting industry featuring crops and traditional Chinese medicinal herbs, and strategies to secure a leading position in both the theory and practice of hydrogen-based agriculture.

Green hydrogen has become an important technological option for building a diversified green energy structure and plays a key role in achieving carbon neutrality goals. This article aims to review the research and development progress of green hydrogen production technology. Based on the current development status and policy background of China’s hydrogen energy industry, this article defined green hydrogen according to the Chinese and international research and development status and focused on hydrogen production from renewable energy water splitting and biomass. The technical characteristics, advantages, and challenges of these technologies were analyzed. Additionally, technologies such as hydrogen production by nuclear energy, methane pyrolysis, green ammonia, and aqua hydrogen, which do not belong to traditional green hydrogen but may play an important role in carbon emission reduction, were explored. Finally, the article summarized the issues existing in green hydrogen production and provided suggestions for the development of green hydrogen in China from aspects such as policy incentives, technological innovation, and market application.
