The paper "Low-carbon remediation of contaminated marine mud sediment for efficient in-situ recycling and application" has been published in the journal ENGINEERING Environment. 

This study addresses the issue of difficult disposal of contaminated marine sediment and its constraints on waste management by proposing a low-carbon solidification treatment using aluminosilicate raw materials to achieve in-situ resource utilization as engineering backfill material. By incorporating a mixture of 25% ordinary Portland cement, fly ash, slag, and 5% river sand, the unconfined compressive strength of the solidified body can reach up to 8.69 MPa, and it can efficiently stabilize heavy metals, making the product comply with environmental safety standards in both China and the United States. XRD analysis reveals that the material is mainly composed of SiO₂, with the formation of secondary phases such as calcium carbonate, iron-manganese oxides, and complex silicates, which collectively endow it with excellent structural mechanical properties. This technology not only provides a feasible path for the large-scale recycling and utilization of contaminated marine silt but also helps improve resource efficiency, protect the environment, and support the realization of carbon reduction and carbon neutrality goals.

The rule-based information extraction for mechanical-electrical-plumbing-specific semantic web has been cited 100 times in Google Scholar.

In view of the strong professionalism and scarcity of labeled data in the building mechanical, electrical and plumbing (MEP) field, which makes it difficult to effectively apply traditional deep learning information extraction methods, this paper proposes a rule-based MEP information extraction method. This method builds a large-scale corpus through a "snowball" strategy and uses suffix matching and dependency path matching algorithms to achieve efficient entity recognition and relationship extraction, respectively. At the same time, the "meta-link" and "path filtering" mechanisms are introduced to mine information beyond complex patterns. Experimental results show that the constructed MEP semantic network achieves good results in terms of entity and relationship extraction accuracy, and significantly outperforms several classic deep learning models in extraction precision. 

Note: Automation in Construction is the most influential journal in the field of civil engineering information technology, classified as a Q1 SCI journal with an impact factor of 11.5 in 2025. The first author of the paper is Wu Langtao, a master's student from the Department of Civil Engineering at Tsinghua University, and I am the corresponding author.

Congratulations to Li Yanyue on successfully defending her Master of Engineering Management professional degree thesis at Tsinghua University!

Li Yanyue's paper is titled "Research on Progress Management of Existing Public Building Renovation Projects Based on PDCA-CCPM". This research addresses the challenges in progress management of existing public building renovation projects by innovatively integrating key chain technology (CCPM) with the PDCA cycle, and has established a PDCA-CCPM progress management mechanism. Key influencing factors were identified through multiple methods, and a two-layer architecture of "project layer - organization layer" was designed. Empirical verification shows that this mechanism has effectively addressed the issue of progress, achieving both an earlier construction period and a simultaneous improvement in quality and safety. This research not only offers a new theoretical integration paradigm, providing a systematic solution for transformation projects, but also aims to drive the improvement of organizational management maturity through project accumulation, possessing both theoretical innovation value and practical guiding significance.

Recently, the "Atoms, Elements and Us" science enlightenment dual picture book, which I participated in compiling, won the first prize of the 36th Excellent Science and Technology Books of the Ten Northern Provinces (Autonomous Regions and Municipalities). 

This set of educational picture books, published by Beijing Science and Technology Press, is specially designed for children aged 3 to 8. It consists of two volumes: "Atomic Transformation: The Power of Nuclear Energy" and "Where Are the Elements: I Come from the Stars". In terms of design, it features hardcover binding, large illustrations, and matte coated paper, ensuring both comfort and durability during reading, while also stimulating children's curiosity through visually striking images. In terms of content, the books adopt an innovative "microscopic-macroscopic" dual perspective narrative structure, transforming abstract scientific concepts into concrete expressions that children can understand. 

The awarding of this book is an important recognition of popular science creation and science communication work. We look forward to sowing the seeds of scientific exploration in children's hearts through this entertaining and educational approach, laying a foundation for their future interdisciplinary learning and improvement of scientific literacy.
