Electron paramagnetic resonance (EPR) spectroscopy stands out as a powerful tool for defect characterization in LiNbO₃ crystals, providing unique insights into the formation and local structure of point defects.

This review analyzes materials and fabrication methods for small-diameter vascular grafts, compares their advantages/limitations, and discusses clinical requirements for optimal graft performance.

Modification strategies of impurity ion introduction, defect engineering, heterojunctions, morphological construction, and facet-oriented engineering have been reported to promote the photocatalytic activities of bismuth-based materials.

An efficient organic photodetector with self-assembled materials demonstrates a responsivity of 0.4 A W⁻¹ and a response of 7.2 μs at 800 nm. The corresponding flexible device exhibits of 0.28 A W⁻¹ and specific detectivity of over 10¹¹ Jones.

NbOCl₂ exhibits exceptional nonlinear optical response, particularly for second harmonic generation (SHG).

Fe-based MOFs (Fe-MIL-53 and Fe-MIL-88B) were prepared using industrial waste via unconventional synthesis procedures. Carbonization was employed to improve the textural properties of these MOF materials, leading to enhanced H₂ and CO₂ uptake.

Sn–Pb mixed perovskite solar cells (PSCs) have better radiation resistance than pure Pb PSCs.

In this work, we introduced an AIE-active small molecule fluorophore (SOTA) based on electron-withdrawing dibenzothiophene-S,S-dioxide, which could be used for highly efficient fluorescence imaging and photodynamic therapy.

B-modified Ca₁₄Zn₆Al₁₀O₃₅:Mn⁴⁺ phosphors achieve high Mn⁴⁺ doping concentration of 5% with QE exceeding 90% and high thermal stability below 500 K.

Eu-MOF and its composite of Pd@Eu-MOF@SA exhibit rapid fluorescence quenching responses to p-nitrophenol. Pd@Eu-MOF@SA can act as a sensitive fluorescence indicator for the catalytic reduction reaction of NaBH₄ and p-nitrophenol with obvious emission color change.
