Cr1/4NbSe2‐Single Crystal Growth and Evolution of Antiferromagnetic Correlated States

Advanced Science, EarlyView.
High‐quality single crystals Cr1/4NbSe2 were synthesized and comprehensively characterized for the first time. Advanced structural, electronic, and magnetic measurements uncover a correlated antiferromagnetic state, resolving longstanding inconsistencies regarding magnetic behavior derived from earlier polycrystal studies.

Time-resolved fast-neutron imaging with a pulse-counting image intensifier [PDF]

, 2006
A new imaging method that combines high-efficiency fast-neutron detection with sub-ns time resolution is presented. This is achieved by exploiting the high neutron detection efficiency of a thick scintillator and the fast timing capability and ...

A high-resolution neutron diffraction and electron diffraction study of the structure and phase transitions in AgTaO3

APL Materials
The high temperature phase transition behavior of the quantum paraelectric material, AgTaO3, has previously been debated in the literature. To elucidate the phase transitions of AgTaO3, we used neutron powder diffraction and established the phase ...

Potassium‐Impurity‐Modulated Self‐Trapped Excitons and Energy Transfer in Phase‐Separated, Mn4+‐Doped Li2HfF6

Advanced Science, EarlyView.
Li2HfF6 contains two spectroscopically distinct self‐trapped excitons (STEs): intrinsic STE1 and redshifted, K‐associated STE2. Potassium incorporation stabilizes STE2, which selectively sensitizes Mn4+ red emission. This work uncovers the often‐overlooked role of trace K impurities, demonstrating impurity modulation as an effective strategy for tuning

Effect of Finite-temperature β-decay Rates on the Rapid Neutron Capture Process

The Astrophysical Journal
β -decay is known to play an essential role in the rapid neutron capture process ( r -process) during ( n ,  γ ) ↔ ( γ ,  n ) equilibrium and freeze-out when the neutron-rich nuclei decay back to stability.

To Be or Not to Be Eutectic: Anomalous Glass Forming Ability Governed by Melt Structural Complexity

Advanced Science, EarlyView.
Challenging the eutectic rule, congruently melting Ti–Cu alloys show greater glass‐forming ability than their eutectic counterparts. This arises from the congruent melt's structural complexity: higher cluster diversity and stronger inter‐cluster correlations from entropy–enthalpy competition.

Pre‐Refinement Prediction of Dopant Site Occupancy in M‐Type Hexaferrites via Hierarchical and Uncertainty‐Aware Machine‐Learning

Advanced Science, EarlyView.
Refined data are extracted from CIF files to construct a hierarchical machine‐learning framework integrating sublattice classification, Fe‐site occupancy prediction, and reliability assessment. External validation yields 96% accuracy for sublattice classification and a macro mean absolute error of 0.0584 for Fe‐site prediction.
