Metal halide perovskites demonstrate excellent photoluminescence and have shown great potential in developing eco-friendly and reversible anti-counterfeiting materials based on polar solvent-induced photoluminescent color changes. However, it remains challenging to simultaneously achieve high quantum yield, excellent stability, and highly sensitive detection of trace polar solvents such as methanol. In this study, a novel terbium-based metal halide 20 % Sb 3+ : Cs 5 TbCl 8 ·6H 2 O was synthesized via solid-phase milling. Sb 3+ doping significantly enhanced its PL performance and stability. The 20 % Sb 3+ : Cs 5 TbCl 8 ·6H 2 O sample showed bright yellow emission with a PLQY of 68.3 % under UV irradiation and reversible water-induced yellow-to-green transition. This enabled the achievement of dual-patterned information encryption and anti-counterfeiting applications by using water-induced 20 % Sb 3+ : Cs 5 TbCl 8 ·6H 2 O and 20 % Sb 3+ : Cs 3 TbCl 6 @PMMA. Furthermore, due to the high charge density of the rare earth ion Tb 3+ and its strong affinity for polar solvents, an ultra-sensitive PL response was achieved for 20 % Sb 3+ : Cs 5 TbCl 8 ·6H 2 O in organic solvents of different polarities. Liquid-phase methanol induced the most pronounced ΔEA value (0.083) among 17 solvents, enabling highly sensitive detection with a limit of 0.01 % after 30 s ultrasonication. Complementary to its solution performance, the material also demonstrated exceptional responsiveness to methanol vapor, where a rapid and reversible PL transition occurred within 7.2 s at 60 °C. This work offers a feasible strategy for designing stimuli-responsive luminescent materials.

The applications of boron-based (B) fuels in propulsion and weapon systems are hindered by inefficient combustion and harsh ignition conditions of B particles. Dual-functional energetic metal-organic frameworks (EMOFs) were synthesized on B surface by incorporating azide ligands as secondary ligands to improve the thermal and combustion properties of B particles. Polydopamine (PDA) interfacial layer was constructed between B and EMOFs to strengthen the interface interaction and facilitate the processes of mass and heat transfer. The mechanisms of EMOFs in eliminating the negative effects of oxide film and enhancing B combustion were analyzed. The results illustrate that the expansion of flame front is driven by the micro-explosion effect of azide ligands, and the flame height increases from 0.46 to 67.9 mm. Concurrently, the generated metal oxides alter the oxygen diffusion pathway by adhering to B surface, thereby significantly enhancing the oxidation process of B. The combustion efficiency of B increases from 60.7 % to 80.4 %, the oxidation temperature lowers by 77 °C, and the flame radiation intensity enhances by approximately 29 %. Crucially, the azide ligands and residual metal oxides exhibit different functions. The azide ligands exhibit the functions of ignition sensitization and micro-explosion at the combustion interface, while the adherent metal oxides promote the efficient oxidation of B particles along two distinct pathways. This innovative strategy of integrating azide ligands and metal oxides offers a novel direction for enhancing the energy release performance of B-based fuels.

A reflective optical fiber gas sensor was developed for the accurate detection of acetic acid gas concentrations in real time. This sensor comprises a multimode quartz optical fiber and a sensing unit coated with a material that selectively responds to acetic acid. The sensing unit consists of a light channel coated with a Ag film, on which a composite film of TiO 2 /functionalized zirconium metal-organic framework (UiO-66–2CF 3 ) is deposited. Upon absorbing acetic acid, the refractive index of the TiO 2 /UiO-66–2CF 3 film increases, enhancing the light absorption at 326 nm while reducing the reflectance. This decrease in the transmitted light intensity enables the accurate measurement of the environmental acetic acid concentration by detecting the difference between the output and input optical intensities. Experiments were performed to investigate the dependence of the sensor performance on the TiO 2 content in TiO 2 /UiO-66–2CF 3 , coating thickness, light incidence angle in the optical channel, and ambient temperature and humidity. In the range of 10–40 °C and 40–80 % RH, the sensor with 45 wt% TiO 2 in the composite, a coating thickness of 55 μm, and an incident angle of 45° yielded an acetic acid gas response sensitivity of 0.0007 absorbance unit/ppm, a response time of 315 s, detection limit of 4.29 ppm, and maximum relative error below 5.0 %. The incorporation of the –CF 3 group into UiO-66 endowed the sensor with excellent humidity immunity, a high selectivity for acetic acid, and long-term stability.

Solid electrolytes are promising candidates for safe, high-energy battery systems. Composite solid electrolytes, in particular, hold the potential to combine high ionic conductivity with stable electrode interfaces. However, a fundamental trade-off often exists between ion conduction and mechanical properties. Here we present a composite solid electrolyte design that decouples ion conduction from mechanical flexibility, achieving a high ionic conductivity of 10.2 mS cm −1 at 25 °C while maintaining close mechanical contact with the electrode. The composite architecture consists of alternating layers of perpendicularly aligned (PA) Li 0.3 Cd 0.85 PS 3 nanosheets, to establish continuous superionic conduction pathways, and Li-containing polyethylene oxide (PEO) layers, to ensure flexibility and interfacial compatibility. At 25 °C, this PA-Li 0.3 Cd 0.85 PS 3 /PEO electrolyte enables Li||LiNi 0.8 Co 0.1 Mn 0.1 O 2 coin cells (stack pressure during assembly <0.5 MPa) to retain 92% discharge capacity after 600 cycles at 0.2 mA cm −2 , with an average cycling Coulombic efficiency of 99.9%, and also facilitates practical use of pressure-less (stack pressure <0.1 MPa) Li||LiFePO 4 pouch cells. This composite design strategy is further validated by substituting Cd with Mn in the inorganic sulfide nanosheets to produce a PA-Li 0.46 Mn 0.77 PS 3 /PEO electrolyte, exhibiting an ionic conductivity of 6.1 mS cm −1 at 25 °C and good mechanical flexibility.

Recent advances in membrane separation technologies have demonstrated significant potential for the efficient removal of oil from wastewater. Nevertheless, the treatment of oily wastewater often encounters harsh operational conditions, including elevated temperatures, extreme acidic or alkaline environments, and severe mechanical abrasion. To address these challenges, this study reports the successful fabrication of a fluorinated polydimethylsiloxane-modified carbon cloth (CC-PDMS-F), which exhibits robust resistance to diverse extreme environments while maintaining high separation performance. The CC-PDMS-F membrane exhibits a high separation efficiency of 97.62%, accompanied by a permeation flux on the order of 1×10 4 L·m -2 ·h -1 for oil/water mixtures. Moreover, for water-in-oil emulsions, the separation efficiency remains as high as 94.86%. Importantly, the variations in contact angle and sliding angle are less than 1% across a wide temperature range, while the contact angle fluctuation remains within 3% under pH conditions ranging from 1 to 13. In addition, the membrane demonstrates excellent long-term stability under continuous mechanical wear, confirming its suitability for practical applications in challenging oily wastewater treatment scenarios.

This study overcomes intracellular antioxidant barriers limiting chemodynamic therapy (CDT) by designing an Fe-Cu bimetallic organic framework (MOF) nanocarrier. Synthesized solvothermally, the spindle-shaped MOF (long axis: 3.5 μm; short axis: 2 μm) exhibits a high specific surface area (381.96 m 2 /g) and mesopores (6.69 nm diameter), as verified by SEM/XRD/FT-IR/BET/XPS. The coexisting Fe 3+ /Fe 2+ and Cu 2+ sites enable synergistic catalysis, achieving 68.2 ± 2.1% doxorubicin (DOX) loading with pH-responsive release in tumor-mimetic acidosis (pH 5.4; 78% cumulative release at 72 h, 7.8× higher than neutral pH). In vitro studies confirm dual functions: efficient glutathione depletion (60% absorbance reduction at pH 6.2, 300 μg/mL MOF) and enhanced hydroxyl radical generation via Fenton/Fenton-like reactions (40× TMB absorbance increase). Cell assays demonstrate low cytotoxicity to normal 293T cells within 48 hours (>80% viability at 25 μg/mL) versus potent synergistic efficacy against HeLa cells under simulated tumor microenvironment (100 μM H 2 O 2 ), where chemo-CDT reduces viability to 35% (31.4-37.5% improvement over monotherapies). This work establishes a self-driven platform for tumor-targeted synergistic therapy.

The methanol oxidation reaction (MOR) remains constrained by the inadequate activity and durability of conventional Pt-based catalysts, particularly across varying pH environments. We present a plasma-tailored synthesis strategy to construct ordered PtFe alloy nanocatalysts anchored on N-doped graphene-carbon nanotube hybrids (PtFe@NGCNT). The synergistic effects of plasma-enhanced alloying and conductive 3D carbon architecture yield ultrafine PtFe nanoparticles (2.13 nm) with protective N-carbon encapsulation. This dual-phase configuration endows PtFe@NGCNT with superior pH-adaptive MOR performance: In acidic media, specific and mass activities reach 2.29 mA/cm² and 2524 mA/mg Pt , surpassing commercial Pt/C by 4.67 and 9.86 times respectively. Alkaline performance further escalates to 13.28 mA/cm² and 6602 mA/mg Pt , exceeding commercial Pt/C by 3.61 and 3.74 times. The catalyst demonstrates remarkable durability after long-term chronoamperometry test and 1000-cycle cyclic voltammetry scanning, attributed to plasma-induced defect engineering in the carbon matrix. This work establishes a universal plasma-engineering paradigm for creating robust, pH-versatile electrocatalysts, propelling the development of next-generation direct methanol fuel cells.

The ongoing advancement of electronic devices toward miniaturization and high power density has made efficient thermal management a critical technological challenge. Phase change materials (PCMs) demonstrate significant potential in this field due to their high latent heat capacity. In this study, a three-dimensional porous aerogel was fabricated using polyethylene oxide (PEO) as a polymer matrix and MXene as a conductive filler via an ice-templating method. Polyethylene glycol (PEG) was then incorporated as the phase-change component through vacuum impregnation, successfully yielding a PEG@MXene/PEO composite phase-change material. This structure effectively prevents PEG leakage during phase transition, achieving a composite PEG loading exceeding 98%. Notably, the PEG@MXene/(5%PEO) composite exhibits a leakage rate as low as 3.90% while possessing a thermal conductivity 1.47 times that of pure PEG. In photothermal conversion tests, the material achieved an efficiency of 92.1% under an optical density of 130 mW/cm 2 . When applied to 18650 lithium-ion battery thermal management, the cells coated with the composite maintained significantly lower operating temperatures than untreated cells during cycling at 0.5 C, 1 C, and 2 C rates. Furthermore, the conductive MXene network endowed the PEG@MXene/(1%PEO) composite with an electromagnetic interference (EMI) shielding effectiveness of 30.16 dB. This work presents a novel strategy for developing multifunctional polymer composites that integrate efficient thermal management with electromagnetic protection.

The need for clean water is the most basic human right. Water scarcity will be one important environmental problem of all countries in the future. Phosphorus in the water environment, come from some untreated industrial, agricultural and domestic wastewater, pose a significant threat to human health and and other biota due to their toxicity. In this study, the modified corn straw biochar (LBC) /sodium alginate (SA) composites (LBS) adsorbents were prepared to remove phosphate from water. The results showed that the best pyrolysis temperature of preparing LBS was 550 °C. When pH was 2 and mass ratio of 550LBC (at 550 °C)/SA was 0.3 g/0.3 g, the adsorption capacity and removal efficiency of phosphate by 550LBS were 61.4 mg/g and 92%, respectively. The adsorption of phosphate by 550LBS was consistent with Langmuir model and pseudo 1st order model (R 2 > 0.95), and reached adsorption equilibrium at 20 min, indicating that 550LBS was monolayer adsorption, physical adsorption was the main adsorption and chemical adsorption was the secondary adsorption. The adsorption of 550LBS was the protonation between surface hydroxyl group and H + , the phosphate adsorption of 550LBS was dominated by ligand exchange and electrostatic attraction. Compared with the maximum adsorption capacity of 550LBS, used 550LBS could be reused, the adsorption efficiency of adsorbents after three tests was still above 41%. This showed that reusability and renewability of 550LBS were good, and promotes its application in water purification processes. Graphical

Sulfur mustard (SM), a highly reactive alkylating agent, remains a significant threat to both military personnel and civilian populations due to its toxic effects. Although substantial research has been conducted, the precise apoptotic mechanisms triggered by SM exposure are not yet fully understood. This study aimed to assess potential differences in the apoptosis following SM-induced acute pulmonary injury via the two routes. An acute pulmonary injury model was developed using SM at an equitoxic dose (1 LD 50 ), administered via either a single intraperitoneal injection or intratracheal instillation. Protein expression levels and mRNA expressions of cysteinyl aspartate specific proteinase-2 (caspase-2), caspase-4, caspase-7, caspase-8, p53, and factor-associated suicide ligand (FasL) were evaluated using immunohistochemistry labeling and polymerase chain reaction analysis. At equitoxic doses, the intraperitoneal SM group exhibited significantly higher protein expression ratios and mRNA expression levels of caspase-2, caspase-4, caspase-7, caspase-8, p53, and FasL in the epithelial cells of the alveolar septa from the right lower lobe of the rat’s lungs than the intratracheal SM group. Both protein and mRNA expression levels increased progressively over time in both groups. The findings indicate that SM in early-phase induces apoptosis through intrinsic and extrinsic pathways as well as possible endoplasmic reticulum stress-related pathway. These insights contribute to a deeper understanding of SM toxicity and offer a basis for developing targeted therapeutic strategies to mitigate its harmful effects. Graphical

The development of efficient catalysts for the selective hydrogenation of dimethyl oxalate (DMO) to high-value oxygenates is of great industrial importance. This study presents a systematic investigation into the promotional effect of gallium (Ga) on Cu/SiO 2 catalysts for tailoring product selectivity in DMO hydrogenation. A series of Ga x Cu 30 /SiO 2 catalysts with varying Ga loadings (x = 0.5, 1, 3 wt%) were synthesized via the ammonia evaporation method. With a moderate Ga doping of 0.5 wt%, the Ga 0.5 Cu 30 /SiO 2 catalyst achieved an exceptional ethylene glycol (EG) yield of 74 %, which is three times higher than its Ga-free counterpart (23 %). Further increases in Ga loading to 1 and 3 wt% redirected the reaction pathway, steering the selectivity towards ethanol (ET, 81 %) and 2-methoxyethanol (MT, 54 %), respectively. Characterization by N 2 O titration, XRD, XPS, in situ FT-IR and H 2 -TPR revealed that Ga incorporation fine-tunes the synergy between metallic Cu 0 (for H 2 dissociation) and Cu + sites (for C=O bond polarization). Concurrently, the generated surface acid sites facilitate subsequent dehydration and hydrogenolysis steps. Consequently, the catalytic performance is directly correlated with the evolution of Cu valence states and surface acidity. This work provides a rational strategy for designing multifunctional catalysts for the selective synthesis of target chemicals from DMO.
