Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

Energy Science &Engineering, Volume 14, Issue 10, Page 4546-4583, October 2026.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

Combustion Characteristics of Flameless Combustion by Reactants Injection Conditions

Journal of the Korean Society of Combustion, 2013
The flameless combustion has been considered as one of the promising combustion technology for high thermal efficiency, reducing NOx and CO emissions. In this paper, the effect of air and fuel injection condition on formation of flameless combustion was analyzed using three dimensional numerical simulation.

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

DSC can be used to determine the enthalpies of formation for the 3d transition metal oxalates

Chemical Thermodynamics and Thermal Analysis, 2022
Differential scanning calorimetry has been used to measure the enthalpy of formation for manganese, iron, cobalt, nickel, copper and zinc oxalate. By adding a flameless combustion catalyst (CuO) and using scans of 2 K min−1 in static air, the values ...

Chemically Self‐Powered Pre‐Activation Strategy for Catalytic Purification of Lithium‐Ion Battery Thermal Runaway Off‐Gas

Battery Energy, Volume 5, Issue 4, July 2026.
The catalytic oxidation method is employed to purify lithium battery thermal runaway fumes. Superoxide (e.g., KO2) provide heat to activate the catalyst, while a blower supplies oxygen and regulates temperature, achieving a safe and efficient purification process with hydrogen and carbon monoxide removal rates exceeding 87%. ABSTRACT During lithium‐ion

Energy‐Efficient Combustion Technologies and Burner Designs for Glass Melting Furnaces

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Glass production is one of the most energy‑intensive manufacturing processes, requiring furnace temperatures above 1600°C. These temperatures depend on burners that must balance thermal efficiency with emission reductions. This article reviews the development of combustion systems in glass furnaces, focusing on their impact on energy ...
