The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

open access: yessteel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.

ROSE bitumen: Mesoscopic model of bitumen and bituminous mixtures [PDF]

open access: yesThe 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.

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

open access: yesEnvironmental 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 ...

The UK Clean Air Act at 70: An interdisciplinary analysis of historical air quality change

open access: yesWeather, 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 ...
