The Effect of Oxygen Staging on Nitrogen Conversion in Oxy-Fuel CFB Environment

Chemical and Process Engineering, 2014
This paper presents a study on nitrogen conversion in oxy-fuel coal combustion in a pilot scale CFB 0.1 MWth facility. The paper is focused on fuel-N behaviour in the combustion chamber when the combustion process is accomplished under oxy-fuel CFB ...

Surface Reconstruction of Ce‐Ion‐Doped Fe‐MOF for Efficient Water Oxidation

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Surface reconstruction plays an important role in catalysts for the efficient oxygen evolution reaction (OER). In this work, we report the designed synthesis of the Ce‐ion‐doped Fe‐MOF (CFM) directly grown on nickel foam via a facile solvothermal route.

Development and Validation of a Next‐Generation Mechanistic Model of the Electric Arc Furnace

steel research international, Volume 97, Issue 9, Page 4779-4804, September 2026.
This study presents a next‐generation mechanistic model of the electric arc furnace (EAF). It describes equations for all crucial processes appearing during the steel‐recycling process in an EAF, i.e., thermal, mass, and chemical. The model was parameterized and validated using industrial EAF data.

Oxide Scale Morphology of Carbon Steels Under Novel Reheating Conditions

steel research international, Volume 97, Issue 9, Page 4655-4667, September 2026.
This study focuses on the changes in oxide scale morphology formed under simulated hydrogen and oxy‐fuel reheating gas atmospheres in comparison to natural gas‐air reheating. Several different properties were analyzed, such as pore structure, ratios of iron oxides, adhesion, and distribution of alloying elements.

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds
