Unbiased Tandem System for Simultaneous Methane and Glycerol Upgrading to Formic Acid Under Ambient Conditions

Small, EarlyView.
A bias‐free photovoltaic‐photoelectrochemical tandem system enables simultaneous methane and glycerol upgrading to formic acid under ambient conditions. The cathode generates hydrogen peroxide for methane oxidation, while the photoanode efficiently oxidizes glycerol.

Hierarchically Engineered Nanocellulose‐Halloysite Composite Foams for Integrated Thermal Insulation and Intrinsic Fire Resistance

Small, EarlyView.
Hierarchically engineered cellulose‐based nanocomposite foams integrate thermal insulation, mechanical robustness, hydrophobicity, and intrinsic flame retardancy. A multiscale hybrid network enables efficient heat and mass transport suppression, promoting char formation and self‐extinguishing behavior without toxic additives.

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

steel 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 ...

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Chitosan Oligosaccharide Cross‐Linked Piperazine Pyrophosphate/Melamine Polyphosphate Modified Silicone‐Acrylic Emulsion‐Based Flame‐Retardant Coating

Safety Science and Technology, EarlyView.
Chitosan oligosaccharides, as the modifier, significantly enhances the crosslinking degree of piperazine pyrophosphate and melamine polyphosphate, enabling the composite coating to form the interpenetrating network integrating Si‐P‐C‐N during combustion.

Do Sovereign‐Environmental, Social and Governance (S‐ESG) Commitments Promote Financial Inclusion?

Thunderbird International Business Review, EarlyView.
ABSTRACT Given the need to respect humanity, the environment, and society, and the progressive development of social responsibility, environmental, social and governance (ESG) commitments and the need for ethical and sustainable finance, this paper aims to examine the impact of sovereign ESG on financial inclusion (FI).

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

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 ...
