Efficient Hydroxyl Diffusion Triggers Surface Hydronium Enrichment and Bulk Proton Participation to Boost Alkaline Hydrogen‐Evolving Reaction

open access: yesAdvanced Materials, EarlyView.
For the first time, we shed light on the surface‐to‐bulk diffusion, induction, and reaction behaviors of OH−, H+, and H2O species on model oxides for alkaline hydrogen‐evolving reaction (HER). We first demonstrate that bulk OH− diffusion significantly affects the generation of proton sources and the diffusion/reaction behaviors of protons, thus ...

Side‐Chain‐Induced Interlayer Slipping in Metalloporphyrin COFs Enables Microenvironment and Spin‐State Regulation for Photocatalytic CO2 Reduction

open access: yesAdvanced Materials, EarlyView.
Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.

In Situ Reconstructed Crystalline–Amorphous CuNi Nanotubes Unifying Activity and Stability for Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
Controlled electrochemical reconstruction creates a crystalline–amorphous CuNi nanotube that unifies catalytic activity and durability for alkaline oxygen evolution. The conductive metallic core and active amorphous oxide shell work synergistically to deliver low overpotential and exceptional stability exceeding 1000 h, offering a new strategy for ...

Mn2+ Ion‐Mediated Zn Dendrite Suppression and Reversible Stripping in Aqueous Zn‐Ion Batteries as Revealed by In Situ Liquid‐Cell TEM

open access: yesAdvanced Science, EarlyView.
In situ EC‐LPTEM directly visualizes how Mn2+ ions regulate Zn electrodeposition and dissolution in aqueous electrolytes. Mn2+ suppresses heterogeneous growth and dendritic elongation while promoting more reversible stripping. These findings reveal additive‐regulated interfacial processes during Zn deposition and dissolution and provide guidance for ...

Chlorine‐Functionalized Silane‐Modified Copper Electrocatalyst for Enhanced CO2 Reduction to Multi‐Carbon Products

open access: yesAdvanced Science, EarlyView.
A chlorine‐functionalized silane modifier (CPTMS) is introduced to cooperatively regulate CO2 reduction to C2+ products on Cu‐based catalysts. Dual‐functional interface sequentially enhances CO2 activation, intermediates protonation and C─C coupling, delivering a 5‐fold increase in C2+ faradaic efficiency (FE, 75% vs.

Fibrillisation and Mechanical Properties of Plasma‐Treated Modification LDPE/PA6 Microfibrillar Composites

open access: yesJournal of Applied Polymer Science, EarlyView.
Plasma treatment enhances interfacial adhesion between LDPE/PA6 via carbonyl group formation. PA6 droplet size heterogeneity reduced to ~850 nm after plasma treatment. Drawing at 160°C produces highly oriented microfibrils with faster throughput. Plasma‐treated MFCs show up to 500% tensile strength increase and 18% higher stiffness.

Relationships among nitrous oxide exposure, neurological injury and biomarkers

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Recreational nitrous oxide (N2O) misuse is an increasing public health problem associated with functional cobalamin (B12) deficiency and severe neurological complications. Despite growing recognition of its harms, the dose–response relationship and clinical value of biomarkers remain unclear.

Translocator protein positron emission tomography as a biomarker for posttraumatic epilepsy and behavioral comorbidities following traumatic brain injury

open access: yesEpilepsia, EarlyView.
Abstract Objective Traumatic brain injury (TBI) induces widespread and persistent neuroinflammation, which is increasingly recognized as a key contributor to chronic sequelae including posttraumatic epilepsy (PTE), cognitive deficits, and neuropsychiatric disturbances. However, reliable biomarkers for identifying individuals at risk for these long‐term
