Quantitative Porosity Engineering of Carbon Electrode in Lithium–Oxygen Batteries with Cell‐Level Gravimetric Energy Density Over 1500 Wh kg−1

open access: yesAdvanced Science, EarlyView.
While large pore volumes in carbon electrodes are believed to boost the energy density of lithium‐oxygen batteries, simulations and experiments show that excessive porosity increases electrolyte demand, reducing net energy gains. Optimizing pore structure for lean electrolyte operation enables >1500 Wh kg−1 pouch cells with good stability, redefining ...

Degradation Mechanism of Phosphate‐Based Li‐NASICON Conductors in Alkaline Environment

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The presence of water in the cathode of a Li‐air battery shifts reactions to produce LiOH, creating a corrosive, alkaline environment. This study investigates the alkaline stability of the common Li‐NASICON solid‐state conductor chemistries through a systematic experimental study combined with computational modeling to understand the degradation ...

Eutectic Transition and Interfacial Modulation of Multifunctional Ionic Liquid Additives for Subzero‐Temperature Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A multifunctional allyl trimethyl phosphonium bis(trifluoromethane)sulfonimide ionic liquid additive forms a eutectic mixture with EC, facilitates Li+ desolvation, and constructs a thin and uniform LiF‐rich solid electrolyte interphase, ensuring stable subzero‐temperature performance of lithium‐ion full cells under practical conditions.

Analysis of Outcomes in Pancreaticoduodenectomy for Elderly Patients Aged 80 and Above: A Retrospective Study Using Inverse Probability of Treatment Weighting

open access: yesAGING MEDICINE, EarlyView.
This graphic summary shows the main clinical outcomes of patients over 80 years of age following pancreaticoduodenectomy (PD) after adjusting for propensity score weighting (IPTW). Compared with younger patients, there was no significant difference in postoperative complication rates or overall survival time in elders. ABSTRACT Objectives With an aging

Topology‐Aware Machine Learning for High‐Throughput Screening of MOFs in C8 Aromatic Separation

open access: yesAdvanced Intelligent Discovery, EarlyView.
We screened 15,335 Computation‐Ready, Experimental Metal–Organic Frameworks (CoRE‐MOFs) using a topology‐aware machine learning (ML) model that integrates structural, chemical, pore‐size, and topological descriptors. Top‐performing MOFs exhibit aromatic‐enriched cavities and open metal sites that enable π–π and C–H···π interactions, serving as ...
