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.

Envisioning the strategic demands for building a modernized powerful nation in 2040 and motivated by the integrated development of new materials, new productive forces, and emerging industries, this manuscript comprehensively analyzes the common requirements of national strategies, relevant policies, and action outlines regarding frontier-disruptive core technologies and critical material development. Based on the advancement and innovation of Materials Genome Engineering's core technologies setting a crucial foundation for key innovations in AI data infrastructure, foundational material models, R&D of new materials, and industrial applications, AI will further accelerate the development of high-throughput intelligent computing software/tools, drive paradigm shifts from high-throughput experimentation to autonomous experimentation, propel the evolution of material AI agents, construct data resource nodes/platforms with standardized specifications, advance new productivity and novel material industries, as well as foster educational paradigm transformation and next-generation talent cultivation. The convergence of Materials Genome Engineering and intelligent science is fundamentally reshaping the underlying logic of material science, technology, and education through a trinity model consisted of ''theoretical reconstruction, technological empowerment, and industrial traction''. This integration represents not merely disciplinary upgrading, but a systematic transformation encompassing scientific paradigms, industrial ecosystems, and talent development models. It will cultivate interdisciplinary professionals crucial for strategic fields such as advanced materials, emerging industries, and future-oriented sectors.

China's science and technology development has entered a critical stage of tackling key challenges and therefore needs to strengthen original innovation. Basic research is the source of original scientific and technological innovation, yet at present China's basic research faces problems such as oversized research teams, homogenized research directions, a lack of core capabilities, and consequently insufficient capacity for original innovation. At the national level, this manifests as team research that is neither specialized nor distinctive and often duplicative, along with an overall pattern that runs counter to diversity. The resulting "resource−driven" research paradigm leads to inefficient use of research resources. As a result, the research ecosystem is degraded, hindering the cultivation and growth of original innovation. This paper argues that, in the realm of basic research, a "small but excellent" paradigm—characterized by small teams that each play to their unique strengths and researchers who are highly specialized and each bring distinctive expertise—has high value for original innovation. Under resource constraints, it can also preserve the overall diversity of national research and the security of the national science and technology chain. Delivering the core value of basic research through rigorous, specialized exploration and original breakthroughs requires each team to focus on a distinctive direction and cultivate it deeply, while team members build deep expertise and tackle hard problems through years of sustained effort. This approach helps foster diversity in the research ecosystem and enables efficient resource allocation, thereby ensuring the resilience of China's scientific and technological development in international competition.

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.

The accurate and efficient extraction of building from remote sensing images is fundamental for applications such as fine urban management, high−precision mapping, and land resource investigation. It is essential to investigate how to leverage image features for intelligent interpretation. This study introduces a global self−attention network with edge−enhancement (E−GSANet) for remote sensing building extraction. The network integrate the edge enhancement module into the encoder backbone, providing the network with a priori knowledge about boundaries, and then establish long−distance dependency relationships between features using the global self−attention feature expression module, enabling the fusion of salient features with edge−enhanced features. A stepwise up−sampling decoding module is designed to fusing the shallow features with rich spatial detail information and the deep features with high−order semantic information to obtain accurate extraction results of buildings. The comparison experiments between E−GSANet and the current mainstream methods is conducted based on two open−source remote sensing building datasets. The quantitative analysis and qualitative demonstrations prove that E−GSANet achieves optimal results across all evaluation metrics, yielding more complete building extractions, precise edges, and higher accuracy. Additionally, network structure ablation experiments and analysis demonstrate the effectiveness of each module.

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.

Ice lithography (IL) is an emerging micro/nanofabrication technique based on electron beam interaction with cryogenic materials, which enables direct writing and transfer of nanoscale patterns through localized electron beam irradiation on solid ice resists formed by gas condensation on cryogenic substrates. Since its inception, this technology has rapidly evolved with distinctive advantages: Firstly, the low electron sensitivity of ice resists permits in situ observation during processing, facilitating high-precision overlay alignment. Secondly, ice films demonstrate exceptional conformal coverage on non-planar substrates, overcoming the planarization constraints inherent to conventional lithography. Thirdly, the solvent-free removal of ice resists via thermal desorption establishes an environmentally benign process, particularly advantageous for processing sensitive and fragile materials. This review systematically examines the historical development of IL, comprehensively summarizes key advancements in technical characteristics, fabrication accuracy, equipment evolution, and process applications, while providing prospects for future directions. It aims to stimulate interdisciplinary research and explore the application potential of this novel technology in emerging fields including three-dimensional optoelectronic devices, biosensing platforms, and flexible electronics.

Post−disaster restoration and reconstruction after major disasters is an open and complex mega−system project. This paper attempts to interpret the historical development of post−disaster restoration and reconstruction in China from the system engineering perspective. First, we define major disaster events and provide classification and outline significant catastrophic events since 1949. Secondly, we use Hall's three−dimensional morphology and Wuli−Shili−Renli system approach to construct the system structure of post−disaster restoration and reconstruction from three dimensions: development stages, critical activities, and science and technology. Then, by examining the specific measures of post−disaster restoration and reconstruction in typical catastrophic events and their relationship with the evolution of human−environment interactions, the traditional, sustainable and intelligent patterns of post−disaster restoration and reconstruction systems are revealed. Finally, the historical experiences of China's post−disaster restoration and reconstruction are summarized in five aspects: institutional advantages and legal guarantees, cross−departmental coordination and information sharing, intelligent monitoring and precise needs assessment, infrastructure and cultural construction, and catastrophe relief and insurance.

Calcium-based batteries have attracted increasing attention as promising candidates for next-generation energy storage, owing to the natural abundance of calcium (approximately 2500 times more abundant than lithium in the Earth's crust), its high volumetric capacity (2073 mA·h·cm-3), and favourable environmental profile. Despite these advantages, their development remains hindered by several fundamental challenges, including inefficient and irreversible calcium metal plating/stripping, narrow electrochemical stability windows of electrolytes, and the scarcity of high-performance cathode materials. Here we provide a comprehensive overview of recent progress in calcium-based battery research, with a focus on calcium metal anode design, rational electrolyte design, development of cathode chemistries, and advances in cell configurations. We critically examine the underlying mechanisms and representative strategies proposed to address current bottlenecks, and discuss emerging opportunities for calcium-based systems in grid-scale and extreme-environment applications. This Review aims to offer a clear perspective on the path toward practical calcium-based batteries and to inspire future research directions for unlocking their full potential.

Artificial Intelligence (AI), as a core driver propelling socioeconomic development, is triggering a dual paradigm shift in scientific research (AI for Science, AI4S) and engineering technology (AI for Engineering, AI4E). This paper systematically elaborates on the driving forces, mechanisms, and practical pathways for the paradigm shift in digital ecosystem network development driven by AI4E. It points out that the traditional development paradigm of digital ecosystem networks faces a fundamental conflict between "rigid architectures and diversified scenarios", necessitating reconstruction with the goals of being "hyper-converged, highly trustworthy, and integrated". The paper introduces the critical foundations, technological underpinnings, and operational mechanisms for this AI4E-driven paradigm shift in digital ecosystem networks. It delineates the main characteristics of the new paradigm from perspectives including mindset, methodology, practical norms, and developmental pathways. Furthermore, it presents practical explorations of AI4E-empowered transformation: proposing the Polymorphic Intelligent Network Environment (PINE) based on Generative AI to forge the "second curve" of network technology systems; introducing On-Wafer Generative Vari-Structure Computing to foster new "chip species" of intelligent computing power; promoting endogenous safety and security (ESS) to empower the resilience engineering of digital system networks, thereby enhancing the endogenous security of AI application systems; and advocating for the construction of the "Hyper-Converged Networks and Intelligent Computing Testbed" as a major scientific facility. This testbed will validate the scientific conjecture that "structure determines efficiency/security/diversity", providing support for building an independent knowledge system, advancing independent sci-tech innovation, and deepening reforms in self-reliant talent training. The study provides both a theoretical framework and technological pathways for the paradigm evolution of digital ecosystem networks in the AI era.
