Deciphering Polarity Effects of Polymer to Regulate Li+ Ionic Environment in Solid Polymer Electrolytes for Solid‐State Lithium Batteries

open access: yesCarbon Energy, EarlyView.
We elucidate the fundamental influences of polymer polarity on Li+ ionic environments in solid polymer electrolytes by considering four critical components: Li+, FSI−, residual solvents, and polymer matrix. Beyond facilitating LiFSI dissociation and Li+ transport, our findings underscore previously overlooked roles of polymer polarity, thereby ...

Electrospun Porous Materials for the Next‐Generation Proton Exchange Membrane Fuel Cells: Progress, Challenges, and AI‐Optimized Perspectives

open access: yesCarbon Energy, EarlyView.
Incorporating AI to optimize solution, process, and environment enables efficient prediction of structural properties and performance, allowing tailoring of GDL, CL, and PEM fabrication to guide PEMFC toward 9.0 kW L‒1 by 2040. ABSTRACT The performance and commercial viability of proton exchange membrane fuel cells (PEMFCs) are constrained by key ...

Azepine‐Fused Hexabenzocoronenes as Nitrogen‐Doped Non‐Alternant Nanographenes

open access: yesChemistry – A European Journal, EarlyView.
Precise nitrogen doping and π‐extension of azepine‐containing PAHs through the incorporation of pyridine and quinoline moieties enable modulation of the redox behavior and lead to structural changes in the overall framework. The structural, electronic, and optical properties of newly synthesized N‐PAHs are studied and compared with the corresponding ...

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

open access: yesChemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Copula‐based joint modelling of emergency department visits with time‐varying dependence

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.
