In the solar-blind region, the development of short-wave ultraviolet (UV) lasers relies critically on high-performance nonlinear optical (NLO) crystals, which require a wide bandgap, a strong second harmonic generation (SHG) response, and a sufficient birefringence to fulfil phase-matching requirements. Although sulfates possess a wide bandgap necessary for short-wave UV applications, the inherent symmetry of [SO 4 ] 2− tetrahedron typically results in an insufficient birefringence. To optimize their birefringence, the introduction of π -conjugated ligands was implemented with a good structural inducer of 4-hydroxypyridine group. It is an effective strategy to markedly augment the birefringence of sulfates as demonstrated in (C 5 H 5 NO) 2 ZnSO 4 ·H 2 O crystal with a birefringence of 0.48 @ 546 nm. Then, based on it, a new UV NLO crystal, (C 5 H 5 NO)ZnSO 4 ·3H 2 O, was obtained by modulating the coordination mode of zinc atoms to mitigate the steric hindrance and increase hydrogen bond sites. It achieves the collaborative optimization of SHG response (1.5 × KH 2 PO 4 (± 0.1)) and optical anisotropy (birefringence ∼ 0.27 @ 546 nm), originating from the synergetic contribution of 4-hydroxypyridine ligands and [SO 4 ] 2− groups. Therefore, this study establishes an innovative strategy for the structural design and performance optimization in NLO materials.

Sensing temperature using fluorescent materials by monitoring alterations in temperature-dependent luminescence characteristics is of great importance for various application fields, including modern industry, scientific research, and daily life. However, there are two main concerns on optical thermometry, and one is the low sensitivity, particularly at elevated temperatures, failing to meet precise measurement demands; another issue is how we can apply the thermometry in in situ environments. Herein, we design and report a hybrid manganese-based halide thermometry exhibiting a relative sensitivity (S r ) of 26.368% K − 1 at 463 K. We further propose a facile synthesis method for photopolymerizable hydrogel films containing the crystallized manganese-based halide thermometry, maintaining the same luminescence and sensing property. The luminescent gel film is applied to chip-based temperature sensing, demonstrating highly accurate performances as smart sensors and flexible electronic materials. This work opens up a new route to design luminescent metal halide thermometry to enrich the library of temperature sensing. Moreover, the luminescent gel film as optical thermometry can be applied in situ from micro-electronics to large-scale industrial systems, supplying new possibilities for advanced sensing and spectroscopy studies.

Sepsis-associated intestinal injury represents a critical pathological event contributing to multiple organ dysfunction, with its pathogenesis closely linked to excessive oxidative stress and hyperactivated endoplasmic reticulum stress. Current clinical interventions lack the capacity for precise modulation of the intestinal microenvironment, while existing nanozyme systems generally face challenges such as low oral delivery efficiency, insufficient stability, and uncertain biosafety. To address these limitations, we developed a novel oral nanozyme delivery system based on 2D V 2 C MXene. Through surface modification with hydroxyethyl cellulose (HEC), we constructed a V 2 C@HEC (CV) nanozyme with enhanced physiological stability and intestinal mucoadhesion. In both in vitro and in vivo studies, the CV nanozyme demonstrated significant reactive oxygen species (ROS)-scavenging capacity. Oral administration of CV effectively mitigated intestinal barrier damage and improved survival in a septic mouse model. Mechanistic investigations suggested that the protective effects of CV may be associated with ROS clearance and modulation of endoplasmic reticulum stress, with inhibition of the ATF6/CHOP signaling pathway potentially serving as one underlying mechanism for its cytoprotective function. In summary, this study not only presents a novel nanozyme material with favorable biocompatibility, excellent stability, and a defined antioxidant mechanism, but also provides an innovative materials-based strategy for the treatment of sepsis.

Assembling the nanochannels of microporous crystalline materials in continuous membranes/coatings has broad applications for separation, selective catalysis, and sensing. Current hydrothermal/solvothermal synthesis methods, however, suffer from long synthesis time, typically hours or days, leading to low fabrication efficiency and intensive energy consumption. Herein, we report an ultrafast synthesis strategy to prepare continuous molecular-sieving membranes, reducing synthesis time to just one to a few minutes—nearly two orders of magnitude faster than traditional ones. This was realized through a combination of a nuclei-loaded seed layer and a drastically increased crystallization rate, preventing substantial dissolution of the seed layer and successfully incorporating it into the resulting membranes. Utilizing this strategy, high-quality zeolite membranes-exhibiting breakthrough separation performance compared to previously reported ones, were rapidly prepared. Interestingly, ultrathin oriented zeolite membranes with ultrahigh separation performance were also prepared in as little as one minute. The drastically shortened synthesis time, together with the demonstrated reproducibility, highlights the practical potential of the UFS strategy for molecular-sieving membranes and coatings.

In this study, poly(lactic acid)-based polyurethanes (PLA-based PUs) made from poly( d -lactic acid) (PDLA) with molecular weights of 2, 5, and 10 kg/mol were melt-blended with poly( l -lactic acid) (PLLA) to enhance its toughness without any additional compatibilizers. The properties of the PLLA/PU blends were systematically investigated considering the M n, PDLA . The results showed that too low or too high M n, PDLA was unfavorable to the original toughness of PLA-based PU and its corresponding toughness of blends owing to their ratio of hard/soft segments, while its tensile strength remained high (> 45 MPa) regardless of M n, PDLA . Given this optimal M n, PDLA of 5 kg/mol, the PLLA/PU blends without and with stereocomplex (SC) crystallites exhibited an elongation at break of 138.3% and 282.5%, respectively, while the latter was 48 times greater than that of neat PLLA. Due to the presence of SC crystallites, the blends showed a fast crystallization rate, which crystallized within 1.2 min, whereas neat PLLA required 53.7 min. The presence of SC crystals increased complex viscosity, which further rose with increasing M n, PDLA due to the higher extent of SC crystallization. This work may provide a strategy for developing PLA-based materials with enhanced toughness. Graphical By incorporating PLA-based PU (PDBU) containing PDLA with different molecular weights, the interfacial interactions are enhanced. The formation of SC crystallites serves as nucleation sites during PLLA crystallization, leading to a reduction in spherulite size. The toughness of PLLA is remarkably improved, with PU-5k-D increasing the elongation at break by approximately 48 times.

Chiral materials have broad applications in optics. Precise regulation of the chiral signal, however, remains highly challenging. Herein, a microfluidic strategy is proposed in which the cooperative action of dual driving forces regulates vortical flow inside droplets. The flow rate and interfacial tension are adjusted to induce ordered Marangoni convection and shear flow within microdroplets. Under these conditions, chiral signals are transmitted both within droplets and across the liquid-liquid interface. Tetrakis(4-sulfonatophenyl)porphyrin and phenethylamine are employed as a supramolecular co-assembly pair to probe the relation between vortex strength/distribution and chiral-signal transfer. Assemblies obtained under microdroplet vortex fields exhibit markedly enhanced and nearly mirror-image circular dichroism (CD) responses in comparison with those prepared under conventional magnetic stirring. These observations confirm that vortical flow efficiently promotes chiral amplification and enantioselective supramolecular assembly. Flow-field visualization by micro-particle image velocimetry (μ-PIV), combined with hydrodynamic analysis, reveals the formation mechanism and evolution of microvortices under the dual driving forces. Overall, this study demonstrates a practical approach to modulating supramolecular chiroptical signals via vortexes in confined environments.

en This link goes to a English section zh This link goes to a Chinese section To address the issues of aluminum (Al) powder agglomeration during combustion and low oxidizer decomposition efficiency in composite solid propellants, this study utilized in situ self-assembly technology to prepare cobalt-based hybrid-coated modified Al powder (Al@CZ). It systematically investigated its regulatory mechanism on the combustion performance of ammonium perchlorate (AP) and ammonium dinitramide (ADN)-based propellants. Characterization results indicate that Co 2+ and 2-methylimidazole form an amorphous coating layer at the dopamine polymerization interface, with variable thickness accompanied by a gradient of Co 2+ loading. Thermal analysis shows that the modified Al may trigger a thermite reaction at the interface in air, reducing the high-temperature oxidation peak. The modified Al exhibits significant catalytic efficiency for the high-temperature decomposition of AP, with the activation energy reduced by up to 34.7% and the peak temperature advanced by 78°C. However, its catalytic effect on ADN is relatively weak. In the propellant system, Al@CZ reduces the width of the exothermic peak of AP-based propellants, increases the burning rate by 10.4%, and decreases the median particle size of the condensed-phase products by 92.1%; for ADN-based propellants, it significantly improves combustion stability, with the maximum pressure increasing by 1.1 times and the pressure rise rate improving by 6.4 times. Combustion mechanism analysis confirms that the coating accelerates Al core oxidation and reduces combustion surface residence time through the synergistic effect of catalytic decomposition of oxidants and interfacial thermite reactions, effectively suppressing molten agglomeration. This study provides a new strategy for controllable combustion regulation in high-energy solid propellants. 摘要 en This link goes to a English section zh This link goes to a Chinese section 为解决复合固体推进剂中铝粉燃烧团聚及氧化剂热分解效率低的问题, 本研究采用原位自组装技术制备了钴基杂化改性铝 (Al@CZ) , 系统研究了改性铝对高氯酸铵 (AP) 和二硝酰胺铵 (ADN) 推进剂燃烧性能的调控机制。测试结果表明, Co 2+ 与2-甲基咪唑在多巴胺聚合界面形成非晶包覆层, 其厚度随Co 2+ 负载量梯度变化。热分析显示, 改性铝粉在空气中可能引发界面铝热反应, 从而降低高温氧化峰值。改性铝对AP高温分解展现显著催化效率, 使活化能降低34.7%, 峰值温度提前78°C。但其对ADN的催化效果相对较弱。在推进剂体系中, Al@CZ可缩短AP基推进剂放热峰宽, 使燃烧速率提升10.4%, 并使凝结相产物中值粒径缩小92.1%; 对于ADN基推进剂, 显著改善了燃烧稳定性, 最大压力提升1.1倍, 增压速率提高6.4倍。燃烧机理分析证实, 该包覆层通过催化氧化剂分解与界面铝热反应的协同作用, 加速铝芯氧化并缩短熔融铝在燃面停留的时间, 有效抑制熔融聚结。本研究为界面工程调控固体推进剂的燃烧提供了新策略。

The advancement of flexible electronics demands dielectric materials beyond single-mechanism regulation. This study introduces a synergistic dual-regulation strategy combining photo-crosslinking and fluorine effects to concurrently suppress relaxation and conduction losses. We fabricated cross-linked hexafluorobutyl methacrylate (HFMA)/β-cyclodextrin (β-CD)/poly(vinylidene fluoride) (PVDF) ternary composite films via ultraviolet (UV)-induced in situ polymerization. Fluorine incorporation effectively inhibited relaxation loss and leakage current, reducing its density from 6.19 × 10 −6 μC/cm 3 (1 wt% β-CD/PVDF) to 1.79 × 10 −6 μC/cm 3 (30 wt% HFMA composite), thereby mitigating thermal/electrical breakdown risks. Simultaneously, the photo-crosslinked structure restricted chain segment mobility, enhancing breakdown strength from 364.35 MV/m (PVDF) to 545.16 MV/m. The synergistic effect significantly improved energy storage performance, achieving a maximum energy density of 7.21 J/cm 3 at 20 wt% HFMA loading—156% of the value for PVDF. This work provides a new design pathway for high-performance flexible polymer dielectrics featuring low loss, high breakdown strength, and superior energy storage density.

Selective capture of structurally diverse molecules remains a major challenge in chemical separations. Here, we introduce dual-acidic deep eutectic solvents (DESs) in which Lewis acids modulate the Brønsted acidity, creating a synergistic environment for the simultaneous extraction of basic and non-basic nitrogen-containing molecules. Brønsted sites, activated by adjacent Lewis centers, preferentially bind basic heterocycles, while the Lewis sites coordinate with non-basic species, achieving unprecedented extraction efficiencies. Mechanistic studies combining FT-IR spectroscopy, density functional theory, and molecular electrostatic potential analysis reveal that proton transfer, Lewis acid–base coordination, and π–cation interactions collectively govern selective recognition. This dual-acidic design strategy is generalizable across different LA-metal DES compositions and robust against competing chemical species. Our findings demonstrate a rational approach to fine-tune cooperative acid functionalities, establishing a versatile platform for selective molecular capture and separations beyond conventional single-acid systems.

Meta-aramid (PMIA) insulating paper contains micron-scale pore defects that limit its dielectric strength and reliability under high electric field and power conditions. Inspired by a sandwich structure, this study employed self-fabricated polyarylate (PAR) nanofiber membranes as outer layers and commercial aramid paper as the core to fabricate hierarchical PAR/PMIA/PAR nanocomposite insulating paper via a scalable hot-pressing consolidation process. The high-aspect-ratio PAR nanofibers formed a dense interwoven network, reducing pore density and mitigating electrical weak points. During hot pressing, the reversible melting of PAR effectively sealed inter-fiber and interfacial pores, while π–π conjugation and strong hydrogen bonding with PMIA fibers ensured robust interfacial adhesion, suppressing electric field distortion from charge accumulation. As a result, the nanocomposite achieved tensile and breakdown strengths of 97.406 MPa and 114.55 kV/mm, representing increases of 51.3% and 204.3% over commercial aramid paper. After thermal aging at 200°C and 24 h UV exposure, breakdown strengths remained at 62.89 and 71.57 kV/mm (vs. 24.62 and 27.30 kV/mm for commercial aramid paper). Even after 20 crumpling-twisting cycles and 100 folding cycles, breakdown strengths exceeded 46.78 kV/mm, demonstrating outstanding durability and structural stability under extreme thermal, mechanical, and radiation conditions. Compatible with industrial wet-laid papermaking and hot-pressing, this work provides a realistic route toward scalable manufacturing of lightweight insulating papers for high-power motors, transformers, and photovoltaic modules requiring long-term dielectric reliability. Highlight Sandwich-structured nanocomposite with robust π–π conjugation interface. 114.55 kV/mm dielectric strength, 204.3% higher than commercial aramid paper. Tensile strength of 97.4 MPa, 51.3% higher than commercial paper.

In this work, poly(L-lactide-co-ε-caprolactone) (PLCL) copolymers with varying ε-caprolactone (ε-CL) contents that ranged from 0% to 10% were synthesized via ring-opening polymerization of L-lactide and ε-CL at 170°C for 1 h. Fully biodegradable PLCL/poly(D-lactide) (PDLA) blends with stereocomplex (SC) crystallites were fabricated through a solution blending approach. The effects of ε-CL content in PLCL on the crystallization behavior, thermal properties, mechanical performance, and degradation behavior of PLCL/PDLA blends were systematically investigated. The successful synthesis of PLCL was confirmed by 1 H NMR and FTIR analyses. The melting peaks observed in the high-temperature region and the characteristic diffractions in WAXD patterns provided evidence for the formation of SC crystallites in PLCL/PDLA blends. Compared with PLCL, the incorporation of PDLA significantly enhanced the crystallization rate, due to the nucleation function of SC crystallites. With increasing ε-CL content in the copolymer system, the T g and crystallinity of PLCL gradually reduced, and the melting peaks of HC and SC crystals shifted toward lower temperatures due to the reduced sequence regularity. A pronounced improvement in deformability was achieved by the presence of ε-CL segments. As the ε-CL content increased from 1.5% to 10%, the elongation at break rose from 12% to 192%, with the morphology of elongated fibrils. Higher ε-CL contents accelerated enzymatic degradation, with mass loss exceeding 75% after 7 days at 10% ε-CL, because the increased chain mobility may facilitate the penetration of water and Proteinase K into the blend, thereby promoting enzymatic erosion. Overall, high-performance PLA-based composites with excellent biodegradability were achieved via SC crystallization and modulation of ε-CL comonomer content. Summary PLCL copolymers with tunable ε-CL content were prepared and characterized. SC crystallization regulated the crystallization and thermal behavior. ε-CL segments enhance chain mobility and improve blend deformability. Enzymatic degradation kinetics were accelerated as ε-CL content increased.

Bismuth-based alloying materials have emerged as highly promising anodes for sodium-ion batteries (SIBs) due to their high theoretical specific capacity, superior volumetric capacity, and suitable operating voltage; however, substantial volume variation during alloying/dealloying and sluggish reaction kinetics critically compromise their cycling stability. To simultaneously address these challenges, this study designed and engineered a unique bismuth nanoscroll (BNR) structure derived from self-assembled nanosheet scrolling. This architecture substantially enlarges the electrochemically active surface area relative to commercial bismuth powder, thereby facilitating efficient reversible Na + intercalation/deintercalation. Consequently, the BNR anode delivers exceptional sodium storage performance: it achieves a remarkable 99.71% capacity retention after 900 cycles at 1A g −1 and demonstrates ultra-long cycling stability for 2500 cycles even at a high rate of 2 A g −1 . Furthermore, a full cell configured with the BNR anode paired with a Na 3 V 2 (PO 4 ) 3 (NVP) cathode maintains a stable capacity of 243.27 mAh g −1 following 250 cycles at 0.1 A g −1 . Beyond introducing a novel synthesis strategy for high-performance bismuth nanowires that exhibit exceptional cyclability in SIBs, this work provides pivotal insights for developing advanced electrode materials targeting high-energy-density and long-cycle-life sodium-ion batteries. Graphical This article investigates the structure–property relationship of spherically compact bismuth nanoscrolls (BNR) for sodium-ion battery anodes. Bismuth has emerged as a promising anode material due to its high volumetric capacity and stable alloying mechanism. The study reveals that the unique spherical architecture, self-assembled from numerous nanoscrolls, enables high performance and long cycle life in sodium-ion batteries through the synergistic effect of accelerated ion transport via one-dimensional channels and effective strain buffering within the internal space.
