The abnormal Fe3+ level is known to cause various diseases, such as heart failure, liver damage and neurodegeneration. In situ probing Fe3+ in living cells or organisms is highly desired for both biological research and medical diagnostics. Herein, hybrid nanocomposites NaEuF4@TCPP were constructed by the assembly of an aggregation-induced emission luminogen (AIEgen) TCPP and NaEuF4 nanocrystals (NCs). The anchored TCPP on the surface of NaEuF4 NCs can reduce rotational relaxation of the excited state and efficiently transfer the energy to the Eu3+ ions with minimized nonradiative energy loss. Consequently, the prepared NaEuF4@TCPP nanoparticles (NPs) exhibited an intense red emission with a 103-fold enhancement relative to that in NaEuF4 NCs under 365 nm excitation. A selectively quenching response to Fe3+ ions for the NaEuF4@TCPP NPs makes them luminescent probes for sensitive detection of Fe3+ ions with a low detection limit of 340 nM. Moreover, the luminescence of NaEuF4@TCPP NPs could be recovered by the addition of iron chelators. Benefiting from their good biocompatibility and stability in living cells, together with the characteristic of the reversible luminescence response, the lipo-coated NaEuF4@TCPP probes were successfully applied for real-time monitoring of Fe3+ ions in living HeLa cells. These results are expected to motivate the exploration of AIE-based lanthanide probes for sensing and biomedical applications. © 2023, The Authors. All rights reserved.

This study addresses the challenge of fabricating high-performance ceramic catalyst scaffolds with complex geometries and optimized properties by introducing an innovative approach using vat photopolymerization 3D printing of high-solid content UV-curable resins. This method enables the creation of a ceramic catalysts with tailored geometries, hierarchical porosities, and enhanced catalytic performances. Composite slurries containing up to 50 wt% ceramic powders (pseudo-boehmite, halloysite nanotubes, and CeO2) were developed and optimized for digital light processing (DLP) 3D printing, with fine-tuned rheological properties to enable the printing of complex 3D structures with deflection angle topologies. Low-temperature sintering at 600 °C yielded crack-free monolithic catalysts with a high specific surface area (112.45 m2/g) and hierarchical porosity. The 3D printed CeO2/γ-Al2O3-HNTs catalysts demonstrated exceptional photocatalytic performance for tetracycline degradation, achieving 92.7 % removal within 2 h, with the 3D printed topology significantly enhancing mass transfer and light utilization compared to conventional powder or honeycomb catalysts. This facile approach enables precise control over the catalyst geometry and composition, offering a versatile platform for designing advanced functional ceramic materials for environmental remediation and catalysis applications. This study highlights the potential of 3D printing technology to revolutionize catalyst design and manufacturing, paving the way for more efficient and tailored catalytic systems. © 2025

Tungsten disulfide(WS2) has been recognized as a promising anode material for rechargeable potassium-ion batteries(PIBs). However, its K-ion intercalation capacity is limited to ~60 mAh·g^(-1). Here, we report a WS2-graphene composite anode which is fabricated through simple filtration of liquid-phase exfoliated WS2 and graphene nanosheet delivers a significantly improved specific capacity of 137 mAh·g^(-1) at a current density of 10 mA·g^(-1). The composite anodes also exhibit remarkable rate capability and long-term cyclability over 500 cycles. These results highlight the WS2-graphene composite structure as a promising anode material for long lifespan rechargeable potassium-ion batteries.

The Size-Dependent Thermal Enhancement of Down-Shifting Luminescence Based on Non-Yb3+-Mediated Energy Migration

The past few years have witnessed extensive attention to the size-dependent up-conversion luminescence thermal enhancement of Ln3+ doped nanoparticles, where the involvement of Yb3+ ions seem to be essential. In this work, a size-dependent down-shifting luminescence thermal enhancement behavior of NaGdF4:Ce3+/Tb3+ has been reported. Specifically, it is the first time to realize the size-dependent luminescence thermal enhancement with a non-Yb3+-involved luminescence process. We demonstrate that the size-dependent luminescence behavior is ascribed to the establishment of energy migration channels via Gd3+ sublattice. These findings offer a feasible way to design the luminescence thermal behavior of nanophosphors with a broader range in terms of both chemical composition and luminescence mechanism. © 2024, The Authors.

A Hexanuclear Titanium-Oxo Cluster with Both Photoprotection and Antioxidant Properties

SSRN 2024年

作者： Wang, Jia-Ning Shen, Chuan-Qi Liu, Jin Nan, Zi-Ang Huang, You-Gui CAS Key Laboratory of Design and Assembly of Functional Nanostructures Fujian Provincial Key Laboratory of Nanomaterials Fujian Institute of Research on the Structure of Matter Chinese Academy of Sciences Fujian Fuzhou350002 China Xiamen Key Laboratory of Rare Earth Photoelectric Functional Materials Xiamen Institute of Rare Earth Materials Haixi Institutes Chinese Academy of Sciences Fujian Xiamen361021 China University of Chinese Academy of Sciences Beijing100049 China

Two hexanuclear titanium-oxo clusters, Ti6O6(OiPr)6L16·2CH3CN (1) and Ti6O4(OiPr)10(OiPrL2)2L22 (2), were synthesized via solvothermal reactions (HL1 = o-nitrobenzoic acid and H2L2 = 1,3-bisbenzyl-2-oxoimidazolidine-4,5-dicarboxylic acid). Compound 1 is a cluster with an octahedral {Ti6O6} core, while compound 2 features as a cluster with chair-shaped {Ti6O4} core. Both the compounds show strong UV absorptions, but their activities to radicals including 2,2-diphenylpicrylhydrazyl (DPPH), hydroxyl, and azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) are significantly different. In contrast to the silence of all of the three radicals to compound 1, compound 2 is able to efficiently scavenge all of them. This obvious difference is attributed to that compound 2 shows higher reducibility, which is probably intrinsically related to electronic donating ligands L2 and OiPrL2. The coexistence of strong UV absorption and great antioxidant activity enables compound 2 to protect skin against photoaging and enhance skin health effectively. These results indicate titanium-oxo clusters bearing redox active ligands are potential for next-generation skincare products. © 2024, The Authors. All rights reserved.
