Ultrathin Freestanding BiFeO3 Membranes Grown by Pulsed Laser Deposition

Small, EarlyView.
Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...

Vibrational Exfoliation of 2D Materials

Small, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Spatially Resolved Strain Mapping In Flexible Oxide Membranes

Small, EarlyView.
High‐resolution synchrotron x‐ray diffraction reveals how strain transfers and distributes within crystalline oriented oxide membranes (10–100 nm thick) on flexible substrates that are subjected to stretching and bending. The study uncovers local strain heterogeneities that deviate from macroscopic averages, providing a crucial framework when ...

The Dimensional Revolution of Phosphorus: From Allotropicity to Battery System Applications

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Phosphorus‐based materials are promising high‐capacity anodes classified by dimension (0D–3D) to systematically explore their properties and composite strategies. When combined with materials such as carbon to form heterostructures, the electrical conductivity and stability are effectively enhanced.
