The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Incipient Fires—Definition, Detection and Extinguishment by Laypersons

Fire and Materials, Volume 50, Issue 1, Page 3-10, January/February 2026.
ABSTRACT The earlier a fire is noticed, the less developed it is and the easier it can be prevented respectively stopped, even by laypersons. Within the research project ‘TEBRAS’ the incipient phase of fires was investigated in detail. In the course of the project, it became apparent that the definition of what exactly the incipient phase of a fire ...

Numerical Modeling of Direct Current Plasma Versus Natural Gas‐Heated Steelmaking Ladles: Validation via Full‐Scale Industrial Measurements

steel research international, Volume 96, Issue 8, August 2025.
This study explores using DC plasma torches with nitrogen as a carrier gas for preheating large steelmaking ladles. Numerical models simulate ladles preheated by 0.7 and 1.5 MW plasma torches, compared to natural gas heating. Results show plasma torches achieve significantly higher bottom temperatures, validated by industrial measurements on full‐sized

Perovskite catalysts for the catalytic flameless combustion of methane [PDF]

Applied Catalysis B: Environmental, 2000
Abstract A new method was employed for the preparation of a set of lanthanum cobaltites of general formula La1−xMxCoO3+δ with M=Ce, Eu and x=0, 0.05, 0.1, 0.2. All the samples thus prepared were nanostructured, thermally very stable and characterised by highly crystalline perovskite-like structure and high surface area.

Research and Application of High‐Sensitivity Grounding Fault Startup Method for Forest and Grassland Distribution Networks Based on Zero‐Sequence Voltage Vector

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper constructs a phase‐to‐earth fault startup method based on the vector form of zero‐sequence voltage, which can enhance the high‐resistance detection capability up to 100 kΩ under different grounded system. ABSTRACT Single‐phase ground faults in forest and grassland distribution networks pose a risk of igniting wildfires, necessitating ...
