High-pressure neutron diffraction at ultra-low temperature

Physical Review Research
Neutron diffraction is a powerful tool in the study of quantum materials and associated emergent phenomena as it allows for direct detection of magnetic structure even at ultra-low temperatures.

Generative Models for Crystalline Materials

Advanced Materials, EarlyView.
Generative machine learning models are increasingly used in crystalline materials design. This review outlines major generative approaches and assesses their strengths and limitations. It also examines how generative models can be adapted to practical applications, discusses key experimental considerations for evaluating generated structures, and ...

Understanding the Dynamics of Nanoparticle Formation and Evolution in Functional Oxides via In Situ SAXS/WAXS

Advanced Materials Interfaces, EarlyView.
In situ SAXS/WAXS enables real‐time tracking of nanoparticle formation and evolution in exsolved and infiltrated Ni‐based perovskites under reducing conditions. The combined technique captures nucleation, growth, and coarsening dynamics with high temporal resolution, providing statistically robust insights into structural and morphological ...

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

Advanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Effect of Collimation on Diffraction Signal-to-Background Ratios at a Neutron Diffractometer

Quantum Beam Science
High diffraction signal-to-background ratios (SBRs), the ratio of diffraction peak integrated intensity over its background intensity, are desirable for a neutron diffractometer to acquire good statistics for diffraction pattern measurements and ...

Optical Manipulation of Multiferroic Phases in BiFeO3 Thin Films

Advanced Materials Interfaces, EarlyView.
At the strain‐driven morphotropic phase boundary, optical control over the multiferroic rhombohedral and tetragonal phase mixture is demonstrated using above‐bandgap light illumination. The photoinduced charge carriers modify the electrostatic environment and induce the conversion into a single tetragonal phase.
