In this study, a novel Sm3+-doped phosphor was synthesized via the high-temperature solid-state reaction, and its properties were systematically characterized. The unit co-substitution strategy was adopted for structural design. Comprehensive structural analysis, including X-ray diffraction (XRD) and Rietveld refinement, confirmed the formation of a stable crystal structure with the successful incorporation of Sm3+ ions. Elemental mapping demonstrated a uniform distribution of elements across the sample. Photoluminescence (PL) studies demonstrated strong orange-red emission under near-ultraviolet excitation, with the main emission peak at 617 nm. At the optimal doping concentration of x = 0.04, the emission intensity reaches its maximum, while higher concentrations result in concentration quenching, which is attributed to dipole-dipole interactions. Additionally, an increase in Sm3+ concentration resulted in a reduction in fluorescence lifetimes. Thermal stability analysis demonstrated that the Ca2GdGa3Ge2O12:Sm3+ garnet phosphor retained 79 % of its initial emission intensity at 398 K, showcasing excellent anti-thermal quenching performance. Additionally, with a quantum efficiency of 22.52 %, the phosphor exhibits promising potential for practical LED applications. This potential was further confirmed by the fabricated white light-emitting diode (LED) device, combining the Ca2GdGa3Ge2O12:Sm3+ phosphor with commercial blue and green phosphors, achieved a high color rendering index (CRI) of 93.2, a correlated color temperature (CCT) of 6156 K. © 2025 Elsevier Ltd and Techna Group S.r.l.

Efficient cleanup of crude oil continues to be a global challenge owing to its inherent high viscosity, which makes it difficult to remove with conventional porous adsorbents. Here, a novel multifunctional aerogel was fabricated through directional freeze-drying, leveraging its photothermal properties and directional structure for the rapid cleanup of crude oil. The aerogel incorporates 2,2,6,6-tetramethyl-1-piperidinyloxy oxidized nanocellulose to enhance Ti3C2Tx (MXene) to construct functional networks, MXene/gold nanoparticles (MX/AuNPs) as photothermal absorbers, and methyltrimethoxysilane for hydrophobic coatings. After 30 compression-release cycles at 90% strain, the strain retention of the aerogel is 85.7%, indicating its mechanical super-elasticity. The as-prepared aerogel showed durable hydrophobicity (145°), high oil/organic solvent absorption capacity (45.7–85.6 g/g), and efficient photothermal conversion, rapidly attaining and sustaining 76 °C. Interestingly, for viscous crude oil that cannot be absorbed for a long time, the aerogel completed the absorption within 10 s after illumination, demonstrating an improved absorption ability of viscous crude oil. Furthermore, the obtained aerogel successfully achieved controlled and rapid light-driven motion, as well as long-lasting photothermal sterilization performance. This work presents a feasible strategy for developing multifunctional composite aerogels, addressing the increasing demands in crude oil separation applications. © 2025

The green synthesis of b-axis-oriented ZSM-5 nanosheets (NSs) is essential for facilitating their industrial production. Here, a set of cost-effective and eco-friendly additives is introduced for the tailored synthesis of thin ZSM-5 NSs with a b-axis thickness of 40 nm with the assistance of small seeds. Through a comprehensive exploration of synthesis methods and electron microscopy analysis, this work elucidates the pivotal roles of seeds and additives in controlling the crystal size and steering anisotropic growth kinetics during the crystallization process. The shortened straight channels of the thin ZSM-5 NSs along the b-axis significantly enhance the rapid transport of molecules within the micropores, thus manifesting a distinct catalytic advantage in the alkylation of benzene with methanol and methanol-to-propylene (MTP) conversion. Notably, the utilization of fluorine-free additives in the synthesis of thin ZSM-5 NSs marks an important step forward in zeolite materials, bridging the gap between laboratory experimentation and industrial scale-up. © 2025 American Chemical Society.

Proteomic analysis of B cells in peripheral lymphatic system reveals the dynamics during the systemic lupus erythematosus progression

In this study, we conducted a comprehensive proteomic analysis of B cells from the spleen, mesenteric lymph nodes(mLN), and peripheral blood mononuclear cells(PBMC) in a time-course model of systemic lupus erythematosus(SLE) using female MRL/lpr mice. By combining fluorescence-activated cell sorting(FACS) and 4D-Data-Independent Acquisition(4D-DIA) mass spectrometry, we quantified nearly 8000 proteins, identifying significant temporal and tissue-specific proteomic changes during SLE progression. PBMC-derived B cells exhibited early proteomic alterations by Week 9, while spleen-derived B cells showed similar changes by Week 12. We identified key regulatory proteins, including BAFF, BAFFR, and NFKB2, involved in B cell survival and activation, as well as novel markers such as CD11c and CD117, which have previously been associated with other immune cells. The study high-lights the dynamic reprogramming of B cell proteomes across different tissues, with distinct contributions to SLE pathogenesis, providing valuable insights into the molecular mechanisms underlying B cell dysregulation in lupus. These findings offer potential therapeutic targets and biomarkers for SLE.
