Interface-Controlled Phase Stability in Polymorphic HfO2_2 Revealed by Machine-Learning Atomistic Simulations

This study utilizes machine-learning atomistic simulations to demonstrate that crystallographic interface matching and orientation, rather than bulk free-energy relations alone, actively govern phase stability and lower transformation barriers in polymorphic HfO2_2, thereby offering a pathway to stabilize metastable phases and direct phase conversion.

Anisotropy of Ultrafast Strain in V2O3V_2O_3 Thin Films: Out-of-Equilibrium Phase Transitions under Interfacial Clamping

This study utilizes azimuth-resolved time-resolved X-ray diffraction to demonstrate that interfacial clamping in V2O3V_2O_3 thin films acts as a static selector for ultrafast phase switching by anisotropically constraining lattice distortions, thereby causing grain families with varying degrees of constraint to exhibit distinct, fluence-dependent structural responses during photoinduced insulator-to-metal transitions.

Effect of Stress and Surface Roughness on Electrodeposition in All-Solid-State Batteries: A Computational Investigation

This study employs a two-dimensional electro-chemo-mechanical continuum model to demonstrate that mechanical stress variations around surface protrusions, rather than surface roughness alone, are the primary driver of nonuniform lithium deposition in all-solid-state batteries, providing critical insights for engineering interlayers to enhance battery reliability.

Breaking Water at Graphene Defects

This study demonstrates that solvation qualitatively alters water dissociation at graphene single vacancies by enabling two competing acidic and basic pathways absent in the gas phase, thereby revealing unexpectedly rich interfacial chemistry with significant implications for carbon functionalization and nanofluidic transport.

Competition between vacancy creation and filling in defect-engineering of hBN

By irradiating freestanding monolayer hBN with ultra-low-energy Ar+ ions, this study reveals that boron single vacancies are the predominant defect formed contrary to simulation predictions, while impurity-driven vacancy filling plays a more significant role than previously assumed, complicating the selective engineering of quantum emitters.

Device Engineering and Performance Optimization of Cu2NiGeS4 Thin-Film Solar Cells with In2S3/MoTe2 Charge-Selective Layers: A Computational Study

This computational study utilizes SCAPS-1D simulations to demonstrate that a Cu2NiGeS4 thin-film solar cell incorporating In2S3 and MoTe2 as charge-selective layers can achieve a predicted power conversion efficiency of 28.44% through systematic optimization of device parameters, significantly surpassing previously reported performance ranges.

High-Temperature ferromagnetism from site-selective filling in (Fe,Ni)6−δ_{6-\delta}GeTe2_2

This study reveals that the record-high Curie temperature of 478 K in (Fe,Ni)6−δ_{6-\delta}GeTe2_2 arises not from homogeneous nickel substitution, but from the spontaneous formation of strain-stabilized, nickel-free Fe6_6GeTe2_2 nano-precipitates that host a unique electronic landscape combining localized moments and spin-polarized itinerant carriers.
