EGMOF: Efficient Generation of Metal-Organic Frameworks Using a Hybrid Diffusion-Transformer Architecture

The EGMOF framework introduces a data-efficient, modular hybrid diffusion-transformer architecture that decomposes inverse design into property-to-descriptor mapping and descriptor-to-structure generation, achieving high validity and hit rates across diverse datasets with minimal training data and retraining requirements.

Ising Supercriticality and Universal Magnetocalorics in Spiral Antiferromagnet Nd3_3BWO9_9

This study extends the liquid-gas analogy to a frustrated spiral Ising antiferromagnet, Nd3_3BWO9_9, by identifying a critical endpoint and a universal Ising supercritical regime that exhibits divergent magnetic cooling efficiency, thereby establishing a new pathway for exploring supercritical phenomena and magnetic refrigeration in rare-earth magnets.

Mechanistic principles of exciton-polariton relaxation

This paper elucidates the microscopic mechanism of exciton-polariton relaxation following upper polariton excitation, revealing a two-step process involving vertical inter-band transition and phonon-induced Fröhlich scattering, while demonstrating that finite material thickness significantly suppresses intraband scattering due to phonon-fluctuation synchronization arising from polaritonic spatial delocalization.

A metallic CrS2_2 phase bridging the gap between two- and three-dimensional dichalcogenides

This paper reports the high-pressure synthesis and characterization of a novel metallic CrS2_2 phase in the form of single-crystalline nanorods, which features a unique ladder-type structure bridging 2D and 3D dichalcogenide motifs and exhibits strong covalent bonding, metallic conductivity, and potential for ionic conduction.

Mitigating the contact resistance limitation of cavitated fine line Ag paste by Laser-Enhanced Contact Optimization

This study demonstrates that combining laser-enhanced contact optimization (LECO) with optimized firing temperatures effectively mitigates the high contact resistance and limited performance of cavitated fine-line Ag paste in PERC solar cells, thereby recovering fill factor and enabling practical low-silver metallization.

Active Learning for Generalizable Detonation Performance Prediction of Energetic Materials

This paper presents an active learning workflow that integrates density functional theory, thermochemical modeling, and machine learning to screen over 70 billion candidates, resulting in a generalizable predictive model and the largest public database of CHNO explosives to date, which reveals oxygen balance as the primary driver of detonation performance.

Cryogenic hydrogen embrittlement of 316plus (EN 1.4420) stainless steel at 77 K and 20 K

This study presents the first experimental characterization of 316plus (EN 1.4420) stainless steel, revealing that while hydrogen precharging causes a modest strength reduction and significant ductility loss (40–50%) at cryogenic temperatures (77 K and 20 K), the material retains notable ductility (~30% reduction in area), confirming its suitability for liquid hydrogen storage applications.

Pressure-stabilized dual-BCC polymorphism in a rhenium-based high-entropy alloy

This study demonstrates that high-pressure compression can selectively transform the hexagonal phase of a ReNbTiZrHf high-entropy alloy into a metastable, Re-enriched body-centered cubic polymorph, resulting in a unique dual-BCC microstructure with enhanced stiffness that is inaccessible through conventional thermal processing.
