Towards a Mean‐Field Braginskii Model for Stellarators

Contributions to Plasma Physics, EarlyView.
ABSTRACT Experiments in the stellarator Wendelstein 7‐X indicate that particle drifts have a significant impact on the plasma in the scrape‐off layer. However, drift effects have been absent in the mean‐field transport codes such as EMC3‐Eirene. For this reason, we present the first steps towards a mean‐field model that incorporates drifts. The code is

Metal‐Free Halogen‐Engineered Carbon Nanotubes for Highly Efficient Oxygen Reduction Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In work employs density functional theory screening to guide the halogen engineering of metal‐free, Cl‐mediated carbon nanotubes for a highly efficient oxygen reduction reaction (ORR). Cl‐mediation optimally tunes the electronic structure and binding energies of oxygen intermediates, delivering an ORR activity rivaling that of commercial Pt/C, high 4e−

Numerical Analysis and Optimization of a Continuous‐Flow pH‐TRC for Steady‐State Low‐Grade Waste Heat Recovery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A steady‐state numerical model is established for a continuous‐flow pH‐TRC for low‐grade waste heat recovery. Based on carbonate and bicarbonate electrolytes, the influences of operating conditions and electrode structure on pH‐driven power generation are clarified.

Amide Methylation Empowers Concentrated Hydrogel Electrolytes for Wide‐Temperature Flexible Aqueous Sodium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An aprotic poly(N,N‐dimethylacrylamide) matrix provides free C=O sites for strong ion solvation, establishing a stable and homogeneous gel phase. This unique polymer network effectively reduces H2O activity, enabling highly concentrated gel electrolytes for high‐voltage, wide‐temperature, and flexible aqueous sodium‐ion batteries.
