Surface‐Selective Pt Enrichment for Stabilizing Ultrathin 2D PtCu Nanosheets Toward Durable Oxygen Reduction

open access: yesAdvanced Science, EarlyView.
Ultrathin 2D alloy nanosheet catalysts could offer exceptional catalytic activity but suffer from severe structural instability. Here, a surface‐selective Pt enrichment strategy via galvanic replacement effectively stabilizes PtCu Nanosheets while preserving their ∼ 1 nm thickness and (111) facets.

Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

open access: yesAdvanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...

Highly Stabilized Ni‐Rich Cathodes Enabled by Artificially Reversing Naturally‐Formed Interface

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The application of Ni‐rich cathode materials is obstructed by interfacial and structural instability. This work proposes a facile and cost‐effective Al‐based vapor‐phase surface reaction strategy on Ni‐rich cathode to maintain its structural integrity from near‐surface to bulk.

Pure Inverse Spin Hall Effect in Ferromagnetic Ni80Fe20/Y3Fe5O12 (YIG) Heterostructures via the Longitudinal Spin Seebeck Effect

open access: yesAdvanced Physics Research, EarlyView.
A pure inverse spin Hall effect (ISHE) is demonstrated in ferromagnetic Ni₈₀Fe2₀/YIG heterostructures via the longitudinal spin Seebeck effect. By employing symmetry‐controlled geometries and reference samples, anomalous Nernst contributions are quantitatively eliminated, revealing intrinsic spin–charge conversion in Ni₈₀Fe2₀.

Fecal Virome Transplantation in Human Disease and Livestock Production: Evidence, Mechanisms, and Translational Challenges

open access: yesAnimal Research and One Health, EarlyView.
Fecal virome transplantation may reshape bacterial communities and host responses while reducing viable bacterial transfer. Preclinical evidence suggests biological activity, but human efficacy remains uncertain, and translation requires product standardization, causal validation, donor–recipient matching, and rigorous biosafety assessment.
