Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

open access: yessteel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

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.

Experimental and Numerical Investigation of Biocarbon Injection Behavior for Electric Arc Furnace Slag Foaming

open access: yessteel research international, EarlyView.
Biocarbon injection is investigated as a promising pathway for sustainable electric arc furnace steelmaking using a combined experimental–numerical approach. Results demonstrate that biocarbon can effectively penetrate slag and generate intense foaming within a defined operating window.

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

open access: yesSafety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

open access: yesThe Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Impact of Environmental Microparticles on Insect Olfaction

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Investigation into the Antibacterial and Freshness Preservation Efficacy of Dry Porous Bags of Biomass Ash from Agricultural Residues

open access: yesBioResources
Biomass ash from agricultural residues, which is typically discarded and causing waste and pollution, was evaluated in tea-bag form as a natural food preservative in this study, addressing research gaps on its effects and safety.
