Photothermal therapy (PTT), a non-invasive tumor treatment, shows promise but is limited in solid tumors by restricted tissue penetration, thermotolerance, anti-apoptotic and immunosuppressive effects. In this study, tumor microenvironment-responsive nanoplatform VARH was constructed based on MXene. Under NIR-II laser irradiation, VARH achieves a high photothermal conversion efficiency of 44.21%. Loaded 2,2'-azobis[2-(2-imidazolin-2-yl)propane] dihydrochloride decomposes at high temperatures to generate alkyl radicals, synergizing with hydroxyl radicals from V 4+ -catalyzed endogenous H 2 O 2 decomposition, enabling chemodynamic therapy (CDT) and thermal dynamic therapy to enhance tumor cell oxidative damage. Triggered by high glutathione, VARH releases ribonucleoprotein (RNP) complexes to knockout heat shock protein 90 (HSP90), attenuating cellular heat resistance and promoting apoptosis. It also enhances T cell-mediated anti-tumor immunity and, with free radicals, promotes tumor cell immunogenic cell death (ICD), achieving immunotherapeutic multi-effect synergy. Integrating nanotechnology with precise gene editing, this study develops a novel multimodal synergistic therapy system, providing new insights for multi-modal treatment R&D and advancing PTT and free radical-based cancer therapies.

To address the sluggish dehydrogenation kinetics and high operating temperatures of LiBH 4 , Ti 2 VC 2 MXene was incorporated with LiBH 4 to modify its dehydrogenation performance. With 40 wt% Ti 2 VC 2 MXene additive, the onset dehydrogenation temperature of LiBH 4 is reduced to 98.31 °C, while the peak hydrogen release occurs at 332.86 °C. Isothermal dehydrogenation measurements demonstrate that the composite rapidly desorbs 9.50 wt% H 2 within 40 min at 325 °C, 10.67 times faster than that of LiBH 4 . Furthermore, the addition of 40 wt% Ti 2 VC 2 MXene effectively lowers the activation energies for the dehydrogenation to 104.76 and 112.99 kJ mol⁻ 1 , respectively. Mechanism studies reveal that the enhanced dehydrogenation performance originates from the in-situ formation of catalytic active species, including Ti 0 , V 0 and Li 3 BO 3 , promoting the cleavage of ionic and covalent bonds in LiBH 4 . Simultaneously, the multiphase Ti/V/Li 3 BO 3 hetero-ensembles create abundant interfacial boundaries, serving as efficient pathways for hydrogen diffusion and accelerating the dehydrogenation kinetics.

Amine intercalation is an efficient way to fine tune and enhance the properties of layered α-zirconium phosphate (α-ZrP), however, its impact on the proton conduction properties of α-ZrP has been rarely explored. In this contribution, a long-chain alkylamine, dodecylamine (DDA), was successfully intercalated into α-ZrP nanoplates. The intercalation was seen to exert both positive and negative impacts on the proton-transport capabilities of α-ZrP. When the intercalant concentration was low, the hydrophobic long-chain alkyl groups of anchored DDA molecules hindered the diffusion of water, causing suppressed proton conduction. With a high DDA concentration, enhanced proton conduction was observed in the intercalated α-ZrP, due to the existence of expanded interlayer spacing and free DDA, which facilitated the diffusion and accommodation of water molecules, leading to an increase in carrier concentration and the formation of hydrogen-bonding networks. The optimized DDA-intercalated α-ZrP (α-ZrP-DDA (1:4)) showed a proton conductivity of 1.11×10-4 S cm-1 at 303 K and 98% relative humidity (RH), which was one order of magnitude higher than that of α-ZrP. Moreover, a humidity sensor based on α-ZrP-DDA (1:4) was fabricated, which could distinguish deep, normal and fast breathing, indicating its potential for practical monitoring of human breath. Our work demonstrates that amine intercalation is an efficient strategy for modulating proton-transport behavior in α-ZrP, thereby broadening its potential applications.

Interfacial engineering in heterostructure photocatalysts is crucial for efficient charge migration, yet achieving rational and controllable interface design remains a major challenge. In this work, SnIn 4 S 8 nanosheets were in situ grown on the octahedral surface of MIL-101(Cr) to leverage the Lewis acid-base properties of Cr and S, thereby enabling the controlled construction of an ion-coordinated interface. The resulting MIL-101(Cr)@SnIn 4 S 8 heterojunction enabled efficient capture and conversion of CO 2 and H 2 O. Furthermore, the Lewis acid-base coordination induces interfacial electron density redistribution, generating a built-in electric field that drives the formation of an S-scheme heterojunction between MIL-101(Cr) and SnIn 4 S 8 , while simultaneously preserving high‑energy photogenerated electron-hole pairs. Consequently, MIL-101(Cr)@SnIn 4 S 8 exhibited superior CO 2 photoreduction performance with H 2 O in the gas-solid phase, delivering a CO evolution rate of 26.9 μmol·g −1 ·h −1 . This work provides a viable strategy for interfacial engineering and demonstrates the application potential of S-scheme heterojunctions in photocatalytic reactions.

Mini/Micro-LED backlight systems require color conversion layers that combine submicron size with high absorption efficiency. However, commercial phosphors are difficult to meet this demand due to their relatively large particle size. The Cs 2 MnF 6 system demonstrates a unique advantage due to its intrinsic high absorption efficiency. In this study, submicron-sized Cs 2 MnF 6 was successfully prepared via anti-solvent synthesis method. Furthermore, a Si 4+ reverse doping strategy was employed (Cs 2 MnF 6 :Si 4+ ) to effectively suppress concentration quenching. At the optimal doping concentration, the emission intensity reaches 3523 times that of the undoped Cs 2 MnF 6 host. Subsequently, surface passivation treatment was applied with a Mn 4+ -free Cs 2 SiF 6 coating. This treatment not only suppressed surface quenching, further increasing the luminescence intensity, but also significantly improved the material's moisture resistance. The finally obtained Cs 2 MnF 6 :Si 4+ @Cs 2 SiF 6 phosphor has an average particle size of approximately 800-900 nm and a high absorption efficiency of 48.4%. Its luminescence intensity is 4.25 times that of the un-passivated sample. And this material retained 75% of its initial luminescence intensity after 240 minutes of immersion in deionized water. In contrast, the untreated sample remained only 16.4%. These advancements highlight the significant potential of this material in mini/micro-LED backlight systems, offering new possibilities for the development of next-generation display technologies.

Curved image sensors hold great appeal in intelligent artificial vision systems, yet current sensor curving techniques still suffer from certain limitations. Taking inspiration from the cuttability and wrap-like transferability of paper-based electronics in three-dimensional curvy architecture and matched hydrophilic functional materials, we propose an image sensor with variable curvature through a vacuum filtration and folding-pasting process assisted by a thermal release tape mask. This method enables the uniform, patterned, hierarchical, and damage-free integration of Mo2TiC2Tx and silver nanowires onto a paper-based substrate. Both convex and concave image sensors are designed and fabricated: the convex type demonstrates wide-field infrared light source tracking when equipped on a robotic dog, while a concave one enables low-distortion imaging with a single lens. Furthermore, by arranging an array of concave curved image sensors around an object and capturing images from different angles, spatial modeling of the object can be realized even in a dark-field environment, showing great potential in bionic compound eyes and artificial vision systems.

The abilities of a strong redox reaction and efficient selective removal of harmful molecules are two important factors in the photodegradation of organic pollutants for ideal environmental remediation. However, it is still an arduous pursuit to acquire shape-selective photocatalytic performance for photocatalysts owing to the randomly destructive effect of free radicals generated on the surface of catalysts toward both harmful pollutants and eco-friendly organisms in nature. Herein, an eco-friendly photocatalyst (TiO2 NSs@Y-zeolite) was synthesized by engineering the highly active {001} facet exposure of TiO2 nanosheets (NSs) via controlling fluorine doping, followed by fixation inside the Y-zeolite crystals. The as-prepared zeolite-fixed TiO2 NSs demonstrated outstanding eco-friendly capabilities with fairly effective shape-selective photodegradation activity. The aniline pollutant can be completely removed over the catalyst under 360 min UV–vis illumination in the aniline and chlorophyll mixed aqueous solution, while the eco-friendly chlorophyll macromolecules remain nearly unharmed with a lower photodegradation rate of 5%. The excellent shape-selective properties of the photocatalyst are ascribed to the sieving effect of the micropores in the Y-zeolite shelter, which only allows the aniline small molecules to access the catalyst surface while preventing the bulky chlorophyll from passing through. We found that it is photogenerated hole carriers, rather than electrons, that are rapidly transferred to the active {001} facets of TiO2 NSs driven by the built-in internal electric field (IEF) to undergo a strong redox reaction. The strong interaction between aniline and the exposed {001} facets, with some possible planar adsorption state, was also first found due to the dipole–dipole/coordination interactions between the nitrogen atom of the dipolar aniline and the Ti4+ site at the surface of the dipolar TiO2 lattice, which is favorable to the efficient photodegradation of the pollutant aniline.

Advancements in dental restoration technologies have created transformative opportunities for enhancing crown repair through intelligent sensing and adaptive design. While modern materials like ceramics and resins improve aesthetic and functional outcomes, persistent challenges in long-term fit, durability, and dynamic pressure monitoring remain unaddressed. This study introduces a groundbreaking approach that synergizes 3-dimensional (3D)-printed colloidal crystal hydrogel crowns with machine learning-integrated resistance strain sensors. The hydrogel’s inverse opal structure ensures robust adhesion to the tooth surface, while embedded strain sensors capture real-time, multidirectional pressure data. Unlike conventional sensing systems, our framework employs machine learning algorithms to dynamically interpret strain patterns, enabling predictive modeling of occlusal forces and adaptive calibration of crown fit. The hydrogel’s temperature-responsive properties, combined with sensor stability under oral environmental fluctuations, ensure reliable long-term performance. Machine learning further enhances diagnostic precision by correlating strain-resistance data with clinical parameters, facilitating personalized adjustments to restoration plans. This work pioneers the fusion of intelligent sensing, material innovation, and data-driven analytics in dental care, establishing a foundation for next-generation adaptive and patient-specific restorative solutions.

The role of Al elements on the combustion behavior of titanium aluminide intermetallics remains not fully understood. Herein, the influence of Al content on the ignition critical condition and burning rate of Ti1−xAlxalloys was investigated by using promoted ignition combustion (PIC) tests under oxygen-enriched atmosphere. Results indicated that the critical oxygen pressure of Ti1−xAlxalloys increases from 0.11 MPa to 0.23 MPa, and the ignition temperature under oxygen pressure of 0.41 MPa increases from 1059.5 ± 4.8 K to 1120.4 ± 2.5 K as Al content increases from 20 at% to 70 at%. However, the combustion rate increases from 11.85 ± 0.13 mm·s−1to 14.05 ± 0.09 mm·s−1as Al content increases from 20 at% to 70 at%. Moreover, the activation energy for ignition increases from 105.44 kJ·mol−1to 153.04 kJ·mol−1as Al content increases from 20 at% to 70 at%. According to the microstructure analysis after combustion, the influence of Al content on the ignition activation energy and burning rate is attributed to multiple factors involving bonding energy, melting temperature, and heat release.

The natural barrier properties of low-permeability clay layers have led to widespread interest in their application in the environmental field. Research on the protective and retardant effects of clay layers on low concentrations of highly toxic thallium is limited. A comparison revealed that the proportion of the active fraction of thallium in illite and montmorillonite was relatively low, indicating that these clays play an important role in thallium fixation. The focus of this work was an experimental investigation of the semipermeable membrane behaviour of illite and montmorillonite. Chemical osmotic differential pressure tests were performed at five thallium concentrations (0.5 mg/L to 50 mg/L), and the chemico-osmotic efficiency coefficients (ω) were calculated. Montmorillonite (ω, 0.048–0.651) has greater chemico-osmotic efficiency coefficients than illite (ω, 0.045–0.437). ω increased as the concentration of dissolved thallium decreased, indicating that the semipermeable membrane effects of the illite and montmorillonite layers were stronger at low thallium concentrations. The effective diffusion coefficients and retardation factors for thallium in illite and montmorillonite were calculated. The findings of this study must be considered in the context of ion competition effects within complex chemical environments. Studying the semipermeable membrane effect of clays on low concentrations of dissolved Tl may aid in clarifying the natural cleaning and barrier properties of clay, as well as support its potential use as an artificial remediation material.

Pseudocapacitive materials employ rapid, non-diffusion-limited faradaic processes to store charge, demonstrating significant potential for fast-charging batteries and supercapacitors. However, the high redox potentials of existing pseudocapacitive anodes substantially lower the overall cell voltage and energy density. Here, a cation-disordered rock-salt lithium titanium oxyfluoride (DRX-Li x TiOF 2 , 0 < x < 2) is reported to reversibly accommodate approximately 1.19 mol of Li + (~ 310 mAh g −1 ) and delivers high-rate performance (exceeding 64.4 C) via pseudocapacitive Li + storage within a low potential window extending down to 0.1 V vs. Li + /Li. This pseudocapacitive behavior is characterized by several structural and electrochemical features: the absence of phase transformation during Li + intercalation, quasi-rectangular cyclic voltammetry curves, sloping charge/discharge profiles and a surface-controlled current response. We further reveal that the pseudocapacitive characteristics originate from a three-dimensional percolation network that facilitates fast Li + migration with low energy barriers, enabled by a cation/anion-disordered structure arising from the mixed occupancy of Li/Ti cations and O/F anions. Owing to its low operating potential and high-rate capability, DRX-Li x TiOF 2 allows a lithium-ion capacitor to attain 4.0 V cell voltage and achieve energy and power densities several times higher than those obtained with conventional anodes, such as battery-type Li 4 Ti 5 O 12 or pseudocapacitive materials like Nb 2 O 5 and TiO 2 .

Efficient and low-cost electrocatalysts play a crucial role in hydrogen production through the electrolysis of water. Molybdenum (Mo) carbide with a similar electronic structure to Pt was selected, and both α-MoC1−xand α-MoC1−x/β-Mo2C electrocatalysts were successfully fabricated for electrochemical hydrogen evolution. A continuous optimization of the hydrothermal and carbonization conditions was carried out for the preparation of α-MoC1−x. The biphasic molybdenum carbide catalysts were further achieved via vanadium doping with a phase transition of molybdenum carbide from α to β, which increased the specific surface area of the electrocatalyst. It was found that the V-MoxC catalyst obtained at a Mo/V molar addition ratio of 100:5 exhibited the best hydrogen production performance, with a β to α phase ratio of 0.827. The overpotential of V-MoxC at η10decreased to 99 mV, and the Tafel slope reached 65.1 mV dec−1, indicating a significant improvement in performance compared to the undoped samples. Excellent stability was obtained for the as-prepared electrocatalyst for water splitting over 100 h at a current density of 10 mA cm−2.
