Energy Science &Engineering, EarlyView.论文陈述 Paper Statement 本研究揭示了不同宏观煤岩类型的差异化控气机制:半亮煤是主要“储气核心,” 光亮煤为关键“渗流通道,” 暗淡煤则是“初期高产贡献者”。这为深层煤层气甜点优选与定制开发提供了关键理论依据。 This study reveals the differentiated gas‐controlling mechanisms of different macroscopic coal lithotypes: semibright coal acts as the primary “gas storage core,” bright coal serves as the critical “seepage channel,” and dull coal functions

High-Temperature Performance Enhancement of Bitumen by Waste PET-Derived Polyurethane
Advances in Materials Science and Engineering, 2022 Bitumen performance enhancement through modification by reactive polymers gained significant attention in the road construction industry. Polymeric bitumen additives, such as polyurethane, improve bitumen properties at low and high in-service ...

ROSE bitumen: Mesoscopic model of bitumen and bituminous mixtures [PDF]
The Journal of Chemical Physics, 2018 We present a mesoscopic model for bitumen and bituminous mixtures. The model, which is based on dissipative particle dynamics, consists of different dynamical entities that represent the different characteristic time scales. Through the stress relaxation function, the mechanical properties of the model are investigated.

Environmental Toxicology, EarlyView.ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

Nanostructured Bitumen with Nanocarbon
Eurasian Chemico-Technological Journal, 2019 Physical and chemical indicators of bitumen quality of grade BND 70/100 with the added carbon nanopowder 2% by weight have been studied by laboratory test methods and analysis. High reaction ability of nanopowder particles and concentration of excess surface and internal energy in them have been determined, which provide the increase of low-temperature

The UK Clean Air Act at 70: An interdisciplinary analysis of historical air quality change
Weather, EarlyView.2026 marks the 70th anniversary of the first UK Clean Air Act, a pivotal moment for air quality in modern British history. Previous narratives on this legislation have largely centred on pollution in London and monodisciplinary perspectives. This article integrates historical research with reconstructed estimates of PM2.5 concentrations to spotlight ...

A water-repelling investigation of 300–450 kg/m3 density porous silicate concrete
Journal of Civil Engineering and Management, 1996 This paper deals with porous silicate convert voluminous water—repellence treatment technological parameters and properties using bitumen emulsions. Bitumen emulsions were prepared using laboratory equipment made up of two electrically heated tanks for ...

European Journal of Science, Innovation and Technology, 2022 The ageing of asphalt and the associated changes in its performance are largely due to the ageing binder it contains. Ageing makes bitumen harder and more brittle. The hardening and embrittlement of the binder has a direct effect on the performance characteristics of the asphalt.
