    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.

    In recent years, light−driven micro/nanomotors have emerged as a novel type of miniature power device, leveraging their adjustable energy input, reversible switching state and remote operability. They have demonstrated broad application prospects in water environment treatment, biomedical fields, and biosensing. This paper aims to systematically summarize the research progress of light−driven micro/nanomotors, elucidate their propulsion mechanisms, and highlight typical applications driven by different types of light (ultraviolet, visible, and near−infrared light). Despite the substantial potential of light−driven micro/nanomotors in various domains, they still face numerous technical challenges, such as low propulsion efficiency, limited motion control precision, and issues with the biocompatibility of materials. Future research directions may include the integration of multiple driving methods, enhancement of light energy conversion efficiency, and development of biocompatible materials. These efforts will promote the performance improvement and application expansion of light−driven micro/nanomotors, bringing revolutionary changes to environmental protection and biomedical fields. By overcoming current technical obstacles, light−driven micro/nanomotors are expected to play a more significant role in future scientific research and practical applications.

    矿产资源的开发和利用是维系现代社会经济发展和人类活动的重要基础。然而,近百年来各类矿产资源的开采和加工产生了大量尾矿矿渣,严重威胁着生态环境和人类社会的可持续发展。如何实现尾矿区的生态重建成为实现可持续矿业的关键。在分析传统尾矿生态修复技术不足的基础上,提出基于土壤发生学原理的尾矿生态修复新策略,即尾矿成土生态工程。具体而言,本策略将尾矿视为成土母质矿物,通过系统性生态工程手段加速成土过程,并逐步将其改造成具有多孔物理结构和化学缓冲特性,能够承载生态功能的稳定类土基质,从而实现对尾矿区的生态重建。尾矿成土生态工程需综合考虑尾矿的特性、本地微生物和植物物种资源及气候条件,因地制宜设计技术路线,构建成套技术体系。最后,基于现有研究进展,提出了尾矿成土的关键基础科学问题和技术应用前景。

    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 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.

    In recent years, major maritime countries and international organizations such as the United States, Russia, Japan, South Korea, the United Nations, and the European Union have issued multiple medium − and long−term ocean strategies and plans, intensifying efforts to promote the development of key marine science and technology fields, striving to make breakthroughs and progress in marine basic research, deep−sea technology, Arctic technology, shipping industry, marine renewable energy, and marine electronic information technology. In the medium to long term, the world's marine technology will present many new development trends. From the perspective of planning issued by major developed countries and international organizations involved in the ocean, this article summarizes and analyzes the main trends in the development of world ocean technology in areas such as ocean basic research, deep−sea fields, shipping industry, marine renewable energy development, and global ocean observation. It also summarizes that there are still many shortcomings in China's ocean technology, such as the gap between its basic research level and that of a world ocean technology powerhouse, insufficient innovation in deep−sea technology equipment, and reliance on imports for key core technologies. On this basis, it is suggested to strengthen the basic research of marine science and technology, and enhance the research and development efforts in key marine technology fields.
