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

Advanced Energy and Sustainability Research, EarlyView.
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.

Research Status and Development Trend of Macromolecular Structure and Model Construction of Different Coals

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...
