Hydrogen-fueled scramjets: Potential for detailed combustor analysis [PDF]

open access: yes
Combustion research related to hypersonic scramjet (supersonic combustion ramjet) propulsion is discussed from the analytical point of view. Because the fuel is gaseous hydrogen, mixing is single phase and the chemical kinetics are well known; therefore,

Faster and Durable: A Cell‐to‐System Validation of a Low‐Degradation Fast‐Charge Protocol for Li‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A physics‐based framework resolving graphite phase‐separation dynamics establishes a predictive, degradation‐aware fast‐charging methodology for commercial Li‐ion batteries. The resulting model‐informed protocol achieves 20%–80% state‐of‐charge in 14 min while matching the long‐term degradation of a commercial 25‐minute EV strategy.

Data‐Driven Modeling of Composition–Processing–Microstructure Relations for Recycled Aluminum Cast Alloys

open access: yesAdvanced Science, EarlyView.
Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...

Synergized Tri‐Phase Anode via Purposive Ba2+ Doping at the La3+ Site in LaFe0.7Ni0.3O3‐δ for Improved SOFC Performance

open access: yesAdvanced Science, EarlyView.
Purposive doping of low electronegative Ba2+ (0.89) at La3+ (1.1) site in LaFe0.7Ni0.3O3‐δ induces the formation of a tri‐phase composite, which shortens Fe─O bond and lowers activation energy, thereby significantly improves electrical conductivity and catalytic activity, and finally offers a record‐high peak power density in La0.5Ba0.5Fe0.7Ni0.3O3‐δ ...
