Boron Nitride Nanomaterials Trigger Immunomodulatory Effects in Human Broncho‐Epithelial Cells by Modulating Eicosanoid Lipid Signaling

open access: yesAdvanced Science, EarlyView.
This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

Nanosized Li2S‐Loaded Polar Porous Carbon Nanofibers as Self‐Supporting Electrodes in Anode‐Free Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
Anode‐free Li–S cells are realized by coupling nano‐Li2S embedded in P‐doped porous carbon nanofibers (Li2S@P‐CNFs) with lithium‐free P‐CNF current collectors. Polar P‐CNFs accelerate Li2S conversion and suppress shuttling, while their lithiophilic, macroporous network homogenizes Li plating for dendrite‐free deposits.

Efficient and Scalable Electrochemical Energy Systems via Peroxide‐Mediated Redox Chemistry

open access: yesAdvanced Science, EarlyView.
We outline reaction mechanisms and catalyst strategies that enable efficient, reversible O2 ⇌ HO2– chemistry. Peroxide‐mediated pathways offer an alternative to the conventional 4e–/O2 route, improving round‐trip energy efficiency in rechargeable zinc–air batteries and supporting scalable hydrogen production without external storage or transportation ...

Crossing the Oxo‐Peroxo Wall for Selective Electrochemical Epoxidation

open access: yesAdvanced Science, EarlyView.
The classical Oxo‐Wall concept is extended to an Oxo–Peroxo Wall framework, showing that meta‐stable oxo species favor peroxo and superoxo formation, decoupling from oxygen evolution reaction (OER). This new understanding enables selective C‐C bond oxidations and provides a predictive alternative oxidation reaction (AOR) volcano for designing metal ...

Atomic‐Level Structural Characteristics of β‐Relaxation in Metallic Glasses

open access: yesAdvanced Science, EarlyView.
Using in situ synchrotron radiation X‐ray techniques, this study experimentally characterizes β‐relaxation at the atomic scale, linking it explicitly to tricapped trigonal prism (TTP)‐like atomic structures and fast atomic motions. Cyclic heating reveals β‐relaxation as irreversible yet reactivatable through rejuvenation, offering unprecedented insight
