Article Abstract
The limited activity and poor long-term stability of oxygen electrocatalysts remain major obstacles to the practical deployment of zinc-air batteries (ZABs). Herein, a heterostructure catalyst, FeNi-LDH@DACs, was constructed by anchoring ultrasmall FeNi layered double hydroxide (LDH) nanodots onto polyhedral FeNi dual-atomic catalysts (DACs), forming a "sesame-ball-like" architecture. This spatial arrangement enables interfacial coupling, where electron transfer from LDH to DACs modulates the d-band center of the FeNi atomic sites and adjusts the adsorption energies of oxygen intermediates. The porous carbon framework of DACs also enhances conductivity, facilitating charge transport during the oxygen evolution reaction. FeNi-LDH@DACs delivers a peak power density of 211.6 mW cm and maintains cycling stability for 500 h at 10 mA cm in ZABs tests. These results demonstrate that engineering heterointerfaces via electronic structure modulation can be an effective approach for improving the performance and durability of bifunctional electrocatalysts for ZABs applications.

Photocatalysis holds significant promise for the reduction of CO to valued chemicals under mild conditions. However, its potential is severely limited by weak CO adsorption and slow proton-coupled electron transfer (PCET) rates. In this work, ZnInS-based catalysts with varying hydroxyl contents were synthesized via the solvothermal method.

The one-photon KV X-ray photoelectron spectra of Na and its hydrated clusters [Na(HO)] ( = 1-6) are dominated by the unusual 1s → 1s3s transition. KV spectroscopy also reveals a pronounced redistribution of the 1s → 1s3p transition cross sections, directly correlated with hydration number and molecular arrangement. Its intrinsic two-step nature, involving simultaneous core ionization and core excitation, enables detailed investigation of solvation-induced electronic structure changes, including dipole-forbidden excitations, core-valence charge transfer, and subtle 1s → V energy shifts.

Transition metal (TM)-doped silicon clusters represent critical model systems for understanding nanoscale hybridization and stability mechanisms. This study provides a comprehensive analysis of structural evolution, electronic properties, and thermodynamic stability in ruthenium-doped silicon clusters (RuSi̅, = 7-11) through integrated experimental and computational approaches. Anion photoelectron spectroscopy combined with density functional theory (DFT/B3LYP), coupled-cluster theory [CCSD(T)], and bonding analyses (AdNDP, NICS, ACID) reveals charge-state-dependent structural transitions, with full Ru encapsulation emerging at = 10 for anions and = 11 for neutrals.

The integration of Mn in NaMnFe(PO)PO (NMFPP) enhances the energy density but compromises the Na mobility and structural stability due to limited electron hopping and pronounced Jahn-Teller effects. To address this, a structurally compatible anionic substitution strategy is implemented by partially replacing PO with bulkier and less electronegative SiO groups. The reinforced cathode exhibits enhanced rate performance, which is attributed to lattice expansion induced by the larger SiO units, thereby facilitating Na diffusion and reducing impedance during charge-discharge processes, as supported by GITT and DRT analyses.

Background: Ultrasound-assisted transdermal drug delivery, or sonophoresis, enhances skin permeability, offering a non-invasive alternative for drug administration. However, its clinical application remains limited because of an insufficient understanding of its underlying mechanisms and optimal parameters. This study investigates the factors influencing ultrasound-enhanced drug absorption and examines its biological effects on skin structures and HaCaT cells, providing a comprehensive analysis of its mechanisms.
