    Based on the evolutionary law of the 50−year long−wave cycle of the world economy, this paper focuses on the core engine of the fifth long−wave cycle—the integrated circuit (IC) industry. It systematically sorts out the development history, current status of the industrial system, and global competitive pattern of China's IC industry from the "6th Five−Year Plan" to the "14th Five−Year Plan" periods. By analyzing the development achievements in key links such as electronic design automation (EDA), design, manufacturing, packaging and testing, equipment, materials, and memory, the paper identifies China's breakthroughs in chip autonomy in national security−related fields and the phased achievements of multiple enterprises ranking among the top 10 in relevant global fields. Meanwhile, it deeply analyzes the industry's existing problems, including homogeneous competition and internal friction caused by "small scale, dispersion, and weakness", lack of fault tolerance and trial−and−error mechanisms between upstream and downstream enterprises, imperfect data statistics and industrial standards, and insufficient transformation of "national efforts" into practical actions. Combined with the development trends of integrated circuits in the post−Moore era—extending Moore's Law, expanding Moore's Law, transcending Moore's Law, and enriching Moore's Law—the paper proposes that during the "15th Five−Year Plan" period, efforts should be made to build leading enterprises, improve coordination mechanisms, increase targeted investment, strengthen basic research, deepen international cooperation, and optimize talent training.

    Biological carbon fixation is crucial to the Earth's carbon cycle and is one of the effective ways to transform CO2 and manage carbon emissions. Chemoautotrophs, with their unique metabolic strategies and environmental adaptability, play an important role in this process. They are able to convert CO2 into valuable organic products, solving the problem of limited CO2 utilization. However, the carbon fixation potential of chemoautotrophs in controlled systems has not been fully explored. This review illustrates the possible challenges of stable culture of chemoautotrophic bacteria in bioreactor. Based on this, a series of physical, chemical and biological methods are proposed to regulate the carbon metabolism of chemoautotrophic bacteria and improve their carbon fixation efficiency. Further, the application prospects of chemoautotrophic carbon fixation in controlled systems are expected, including improving the primary productivity of natural ecosystems, reducing carbon emissions in specific sites, and producing high−value microbial by−products. This review highlights the advantages and challenges of these applications, providing important insights into carbon capture, fixation and conversion by chemoautotrophs.

    This article focuses on amorphous matters and reviews recent advances in amorphous materials and physics. More recently, more than 30% of the lunar soil collected by China's Chang'e-5 mission was found to be glassy, further confirming the widespread existence of amorphous matter in the universe. Topological order and inhomogeneity may be hidden behind the seemingly chaotic structure of amorphous materials, so amorphous matters have strange genetic, sensitive and relaxation behaviors, and show a series of excellent physical and chemical properties, such as extreme stability, super-plasticity, super mechanical behavior and excellent soft magnetic properties. The new generation of Zr-based and Fe-based amorphous alloys developed based on order regulation and high flux technology are successfully applied to core components such as folding mobile phone hinges and new energy vehicle motors, indicating that amorphous matters have irreplaceable application advantages. The future development of amorphous matters should focus on introducing a new paradigm of material research, attaching importance to the importance of process innovation, promoting the cross-integration of multi-disciplinary fields, giving full play to the advantages of advanced characterization technology and large scientific devices, and creating a whole-chain innovation model for production, university and research, so as to actively promote the rapid development of amorphous materials and physics, and expand the application of amorphous matters in high-tech fields. Make the future of mankind a better place.

    The discovery of bilayer nickelate superconductor La3Ni2O7 under high pressure has attracted worldwide attention, in which theoretical research plays a vital role. So far, theoretical calculations show that the two eg Ni 3dx2-y2 and 3dz2 orbitals in La3Ni2O7 are crucial to the formation of superconductivity, while the O2 p orbital also appears on the Fermi surface. Multi-orbital models have been proposed based on the above analysis. Various calculations show that La3Ni2O7 has a s± wave pairing symmetry although other pairing symmetries can be obtained. Theoretical calculations shows that the superconducting mechanism is unconventional and closely related to antiferromagnetic fluctuation. The vacancy of apical oxygen has a significant impact on the occurrence of superconductivity. The discovery of trilayer nickelate superconductor La4Ni3O10 under pressure has further enriched the family of nickelate superconductors. And its electronic band structure, multi-orbital model, superconducting pairing symmetry and so on have been investigated and explored theoretically.

    With the convergence and innovation of emerging information technologies, Digital Twin (DT) technology has become a key enabler for digital transformation and the evolution of intelligent systems. It has been widely applied and received significant attention in fields such as industrial manufacturing, smart cities, and intelligent transportation. However, existing research on traditional DT technologies has predominantly focused on the modeling and analysis of physical entities ("objects"), with limited systematic integration of "human" and "environmental" factors. The lack of exploration into human−environment interactions makes it difficult for current digital twin frameworks to meet the advanced demands of complex intelligent systems for multi−level, comprehensive interaction capabilities. In view of this, this paper innovatively introduces the "object−human−environment" interactive vision and comprehensively and systematically analyzes the research frontiers and progress of digital twin technology from the three core dimensions of intelligent physical entity (object), intelligent individual (human), and virtual−real fusion environment (environment). Firstly, the paper analyzes the traditional digital twin technology system with "object" as the core and focuses on its theoretical origin, framework, and application. Secondly, it discusses the definition, development context, national policies, and core technologies of digital people driven by AI. Finally, expand the vision to the dimension of "environment" and explore the application practice of "environment" in multiple scenes of the meta−universe, deeply discuss the deep integration and interaction mechanism of the three elements of "object", "human" and "environment", reveal how the three interact and promote each other, and provide support for the construction of the meta−universe. Furthermore, this study discusses the current research challenges and future development trends of digital twin technology from the perspective of "Object−Human−Environment" interaction and proposes three key research directions: (1) developing an intelligent, multi−layered data fusion framework; (2) exploring AIGC−enabled intelligent virtual−real mapping and native virtual evolution; and (3) constructing novel virtual economy architectures and intelligent governance systems. The research outcomes provide both theoretical foundations and practical insights for building next−generation digital twin systems characterized by multi−agent collaborative perception, multimodal intelligent interaction, and closed−loop integration of virtual and real environments.

    Under the background of the superpower games, the United States actively promotes the de Sinicization of key minerals and constructs a strategic blockade against China, which may seriously affect China's normal resource rights and interests. Based on the critical mineral related data released by the United States Geological Survey from 2013 to 2022, quantitative research was conducted from three perspectives: import dependence, market dynamics, and supply risk. The changes in the security of the critical mineral supply chain in the United States were elucidated, and the means and characteristics of strengthening the security of the critical mineral supply chain in the United States were analyzed. About 90% of critical minerals in the United States rely on imports, with China as its top supplier. The market dynamics of about 70% of critical minerals fluctuate violently, and market instability may amplify the import risk of critical minerals in the United States; About 32% of critical mineral supply risks are high or keep rising, and the production capacity of critical minerals further shifts to some thirdworld countries in Asia, Africa and South America, and the escalation of geopolitical crises may exacerbate mineral supply risks. Based on the analysis of the security situation of the key mineral supply chain in the United States and its security measures to strengthen supply chain, suggestions have been put forward, including systematic planning to respond to the strategic game of key minerals, enhance the influence on the international mineral resource market, deepen overseas development cooperation, and strengthen risk prevention and control.

    The impact of global warming and how to deal with it are topics of widespread concern across various sectors of society. This paper focuses on the impacts of global climate change on dryland. Over the past fifty years, the temperature has risen at the rate of 0.32℃ /decade, and climate warming has enhanced the evaporation capacity and consequently expanded the world's arid regions by approximately 2.61×106 km2. The frequency and severity of droughts has also increased, with an average of 251 meteorological droughts occurring in 34 major river basins. The drought heatwave compound events and flash droughts are becoming more common. The duration of heat waves has extended from 8 to 12 days on average. With climate warming, the water availability has decreased with increased water uncertainty. Concurrently, greenhouse gas emissions increased and carbon sequestration reduced. Desertification has aggravated, and poverty?stricken area has expanded. In light of these challenges, it is recommended to vigorously advocate carbon emission reduction strategies to curb the pace of climate warming, strengthen international cooperation, formulate a global action plan to mitigate the continuous expansion of arid areas, build a cooperation mechanism to address climate change in terms of policy, management, education, science and technology, finance and other aspects, and solve the "double dilemma" of desertification and poverty in multiple ways.

    The sustainable operation of wearable /implantable medical devices is crucial for the next generation of personalized medicine. However, limited battery capacity is a critical challenge for most wearable /implantable medical electronics. The human body is rich in mechanical and chemical energy (such as respiration, exercise, blood circulation, oxidation and reduction of glucose, etc.), so it is considered a feasible method to obtain mechanical energy from the body to supply power for wearable /implantable medical electronics. A variety of new methods for developing in vivo energy harvesters have been proposed to power wearable /implantable medical electronics. Based on this background, we here focus on the recent research progress of energy harvesters based on piezoelectric or triboelectric effects, with an emphasis on the fabrication, materials design, energy output, durability, as well as their typical applications in biomedicine and evaluation criteria. Finally, according to the actual needs of wearable /implantable medical electronics, the prospects and challenges of nanogenerators are discussed.

    As a broadly interdisciplinary field, Human-Computer Interaction (HCI) has become a significant driving force in advancing the development of the information age and bringing computing technologies to the public for everyone to use. This article reviews key topics in the field of HCI until now, and it also explores the evolutionary path of ideas behind the technologies, presenting a more macroscopic philosophical understanding of human-computer relationship and future innovation in the human context. The article is divided into four parts: (1) It briefly describes the position and contributions of HCI; (2) It analyzes the evolution of current technological phenomena from the history of HCI; (3) By understanding the antibiosis issues between humans and computers, the article also applies“Human-Engaged Computing”theory to a discussion about the ideal relationship between humans and technology; (4) Based on the above, we also present suggestions for future development from five aspects: academic thought, research and education, societal impacts, information dissemination, and technology design.
