Interface Engineering for Expanded Stable Polarization Regime Upon Cycling in Ferroelectric Hf0.5Zr0.5O2

Small, EarlyView.
Interfaces can be crucial on the properties of ferroelectric HfO2. In this work, it is demonstrated that a top nanolayer of ZrO2 significantly improves the ferroelectric properties of epitaxial La‐doped HfO2 films on SrTiO3(001). Endurance reaches 1011 cycles with a technological window of 108 cycles, in which the remanent polarization variation is ...

Mixed‐Dimensional Epitaxy of Aligned 1D vdW Nanowires on Low‐Symmetry 2D vdW Materials: Sb2X3 on ReX2 (X = S, Se)

Small, EarlyView.
Highly aligned mixed‐dimensional vdW heterostructures are achieved through vdW epitaxy of 1D Sb2X3 (X = S, Se) nanowires on low‐symmetry 2D substrates (e.g. ReX2). Reduced substrate symmetry enables aligned nanowire growth and well‐defined vdW interfaces. Atomic‐scale characterization reveals specific epitaxial relationships and stacking‐fault defects.

Role of 1D and 2D Materials in Achieving Transparent and Flexible Lithium‐Ion Batteries for Wearable Electronics

Small, EarlyView.
Hybrid 1D–2D architectures redefine material design strategies for TFLIBs by decoupling competing performance parameters. This approach accelerates the transition of TFLIBs from proof of concept to practical wearable technologies. ABSTRACT Transparent and flexible lithium‐ion batteries (TFLIBs), enabled by advanced nanomaterials and flexible ...

Fusion Energy and Tritium Fuel Cycle: Hydrogen Isotope Separation Technologies and Sorbent Materials

Small Methods, EarlyView.
This review surveys sorbent‐based materials for hydrogen isotope separation, a key challenge in fusion fuel processing. Different types of adsorbents are compared in terms of selectivity, kinetics, and operational practicality. Limitations of cryogenic operation and tritium compatibility are highlighted, providing guidance toward efficient, low tritium

Determining bismuth content in GaAsBi alloys by energy‐dispersive X‐ray spectroscopy: A case study with multiple sets of k*‐factors for analytical transmission electron microscopy

Journal of Microscopy, EarlyView.
Abstract Measuring the bismuth (Bi) content of ternary gallium arsenide bismuthide (GaAsBi) alloys is important because it sensitively influences their bandgap, and Bi is known to segregate vertically to the surface and sometimes also laterally during growth, so elemental distribution maps need to be quantified.

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...
