Incorporating Si into Sb2Se3: Tailoring Optical Phase Change Materials via Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
We study the structural, optical, and thermal effects of adding silicon to Sb2Se3 and demonstrate that the as‐deposited solid solution phase segregates after electro‐thermal switching, creating a nanocomposite with effective‐medium properties and a phase‐change response.

NDST3‐Induced Epigenetic Reprogramming Reverses Neurodegeneration in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
NDST3‐mediated epigenetic reprogramming revitalizes neuronal circuits in the substantia nigra and striatum to halt dopaminergic neuron degeneration and restore motor function in Parkinson's disease models. This strategy promotes neuronal maintenance and functional recovery, highlighting NDST3's therapeutic potential in neurodegenerative disorders ...

An Advanced High‐Performance Ultrafast Ammonium‐Ion Aqueous Battery Based on Dual‐Metal Redox Open Framework Molecular Magnet

open access: yesAdvanced Science, EarlyView.
The Prussian Blue Analogue molecular magnet KMnFeHCF is demonstrated as a high‐performance cathode for ultra‐fast aqueous ammonium‐ion batteries. A full cell using KMnFeHCF and graphite delivers ~71 mAh g−1 at 1.25 A g−1 and ~51 mAh g−1 at 2.2 A g−1, retaining 50% capacity after 1850 cycles. Its scalability, cycling stability, and low cost offer strong

Atomically Resolved Electron Reflectivity at a Metal/Semiconductor Interface

open access: yesAdvanced Science, EarlyView.
An atomically flat interface is achieved in the incoherent Al/Ge heterostructure using molecular beam epitaxy (MBE). Scanning tunneling microscopy (STM) reveals a laterally periodic modulation of electron reflectivity with atomic resolution at the commensurate Al/Ge interfacial lattice, originating from the local electronic states.

Wave‐Partition‐Governed Dual‐Site Spallation in Single Crystals

open access: yesAdvanced Science, EarlyView.
Crystalline anisotropy shapes shock‐wave propagation and the resulting damage evolution in single crystals. Large‐scale molecular dynamics and damage modeling uncover a dual‐spallation mechanism driven by anisotropic elasticplastic wave separation, which mitigates damage accumulation.

The resistance of selected high strength alloys to embrittlement by a hydrogen environment [PDF]

open access: yes
Selected high strength iron base and cobalt base alloys were resistant to degradation of mechanical properties in a one atmosphere hydrogen environment at ambient temperature. These alloys were strengthened initially by cold working which produced strain

Dynamic Interfacial Modulation in Pt@Ga Liquid Metal Systems

open access: yesAdvanced Science, EarlyView.
This work introduces a facile dissolution‐reconstruction approach to prepare the Pt@Ga liquid catalyst by dissolving Pt in molten Ga and then using electrochemical treatment to reconstruct Pt on the Ga support, which provides a new design strategy for liquid‐metal catalysts and enhances the understanding of oxide‐modulated segregation, offering new ...
