Metal-organic frameworks (MOFs) have become a focal point of interest owing to their ability to remove contaminants from wastewater. However, the typical powder form of MOFs is difficult to recover after use, which hinders their practical application. In this research, UiO-66-OH gel was synthesized at room temperature. On this basis, Co was doped into UiO-66-OH gel to obtain a series of Co@U-OH-X composites. The [email protected] exhibited an adsorption capacity for TC that was 5.1 times higher compared to the UiO-66-OH gel. Furthermore, the influence of pH, coexisting ions, humic acid, and original concentration of TC on the adsorption of [email protected] was examined. The composite materials demonstrated an exceptional capacity to adsorb TC (182.31 mg·g -1 ), which surpassed the performance of numerous previously documented adsorbents. The pseudo-second-order kinetic model and the Freundlich isotherm model efficiently accounted for the adsorptive interaction. Thermodynamic adsorption analyses indicated that the interaction occurred spontaneously and accompanied by heat absorption. After four cycles, there was only a 12.7% reduction in the removal rate of TC, which suggested that the composite materials were recyclable. [email protected] showed remarkable adsorption capacity even in settings with minimal TC concentration. The exceptional adsorptive performance, superior recyclability and aqueous stability established Co@U-OH-X composites as a viable adsorbent contender for eliminating TC.

Electrochemical CO2 reduction (CO2RR) presents a scalable route to decarbonize steelmaking by producing CO-rich syngas from captured CO2 and renewable electricity. Here, we report an inverse ZnO/AuCu electrocatalyst with a tunable oxide-metal interface. The catalyst achieves a CO Faradaic efficiency of 85.6% and a current density of −158.2 mA cm–2 at −1.0 V vs. RHE, demonstrating industrial-level performance. The engineered interface enables precise control over the CO/H2 ratio in the produced syngas, spanning from 0.3 to 10.3. This flexibility allows for tailoring the syngas to align with the thermochemical requirements of iron ore reduction. density functional theory (DFT) calculations reveal that the ZnO/AuCu interface synergistically promotes CO2 activation by lowering the energy barrier for the rate-determining *COOH formation, resulting from an elevated d-band center, and a reduced work function. Life cycle assessment (LCA) demonstrates that integrating ZnO/AuCu catalyst into blast furnace workflows could reduce CO2 emissions by ∼80% and improve electricity utilization by an order of magnitude relative to fossil-based pathways. This work establishes a materials-driven strategy that bridges catalyst design and industrial carbon recycling, paving the way for sustainable steel manufacturing.

Herein, we report a high-performance electrocatalyst for the lattice-oxygen-mediated (LOM) alkaline oxygen evolution reaction (OER), a key process for green hydrogen production. By employing a simple solvothermal and chemical vapor deposition (CVD) approach, we successfully synthesized CNT-bridged Ni/Co bimetallic nanoparticles on a Co3O4 nanoarray matrix supported by nickel foam (NF). The in situ grown CNTs and Ni/Co nanoparticles introduce abundant oxygen vacancies (Ov), significantly lowering the Gibbs free energy (ΔG) of *OOH desorption and enhancing the OER kinetics. Additionally, edge dislocations in Co nanoparticles induce lattice distortion and strain modulation, optimizing electron transfer and boosting catalytic efficiency and stability. As a result, the Ni/Co-CNTs-Co3O4/NF electrocatalyst achieves an ultralow overpotential of just 133 mV at 10 mA cm–2, maintaining structural integrity and excellent stability over 72 h at 20 mA cm–2. Theoretical calculations further confirm that Ni/Co nanoparticle incorporation tunes the d-band center, facilitating the adsorption–desorption balance of oxygen-containing intermediates and accelerating the OER process. When integrated into an alkaline electrolyzer, the Ni/Co-CNTs-Co3O4/NF electrodes demonstrate a remarkably low operating voltage of 1.58 V at 10 mA cm–2 and impressive durability for over 24 h at 20 mA cm–2. These findings highlight the strong potential of the Ni/Co-CNTs-Co3O4/NF electrocatalyst for the application of scalable, high-efficiency water splitting technology.

Improving drug loading and dissolution of poorly water-soluble active pharmaceutical ingredients (APIs) remains a major challenge in formulation development. Here, we integrate atomic force microscopy (AFM) adhesion-force profiling with supercritical antisolvent fluidized-bed (SAS-FB) technology to establish a predictive framework for drug–carrier selection. Enzalutamide (ENZ), a highly crystalline and poorly soluble biopharmaceutics classification system (BCS) Class II compound, was used as a stringent model drug. Single-particle force spectroscopy measurements quantified nanoscale interaction forces between SAS-processed ENZ microcrystals and seven carrier materials. Among these, lactose T70 exhibited the highest adhesion force, which strongly correlated with its superior encapsulation efficiency (EE = 92.7 %) under identical SAS-FB processing conditions. Statistical analysis revealed a robust linear relationship between mean adhesion force and EE (R² = 0.94453), identifying adhesion force as a quantitative predictor of drug deposition efficiency. This predictive capability was further validated using three additional model compounds (naringenin, dihydromyricetin, and luteolin). Comprehensive physicochemical characterization (SEM, PSD, EDS, DSC, XRD, FT-IR, and ¹H NMR) confirmed effective deposition of ENZ onto lactose T70, particle-size reduction, preserved chemical integrity, and SAS-induced polymorphic transformation. The optimized ENZ@SAS-FB(T70) formulation achieved a 5.5-fold increase in dissolution compared with unprocessed ENZ, attributed to uniform coating, enhanced wetting, and improved dispersion of micronized drug on the carrier surface. Collectively, this study establishes AFM-guided carrier screening as a mechanistic and efficient strategy for optimizing SAS-FB formulations. By linking nanoscale adhesion forces to macroscopic encapsulation outcomes, this framework offers a generalizable approach for accelerating the development of high-performance formulations for poorly soluble APIs.

In order to enhance the actuation performance of photoresponsive hydrogels in view of their slow response rate and limited functionality, a photoresponsive hydrogel was prepared in this study. The hydrogel was constructed with a thermo-responsive poly(N-isopropylacrylamide-co-acrylamide) (P(NIPAM-AM)) matrix cross-linked by chitosan (CS) and incorporated a photothermal conversion component based on the Fe3+/tannic acid (TA) complex. We characterized the hydrogel’s microscopic morphology and measured its water absorption/desorption rates, mechanical properties, temperature sensitivity, photothermal conversion ability, actuation performance, and sensing performance. Results show that adding chitosan and acrylamide together produced a more tightly cross-linked structure. This improved the hydrogel’s mechanical strength, water retention, and actuation performance. Key performance values include a maximum stress of 101 kPa, maximum strain of 100%, and maximum bending angle of 104.8°. The hydrogel achieved a fast actuation response time of 0.732 s, a bending rate of 0.22 mm/s, and a conductivity of 1.154 (Ω·m)−1. It also demonstrated efficient photothermal conversion, NIR-responsive actuation, and conductive sensing performance. This work provides a useful strategy for developing high-performance light-responsive smart materials and a practical solution for multifunctional flexible actuators.

In order to avoid the interference of autofluorescence and improve tissue penetration capability of carbon quantum dots (CQDs) in biological imaging, the synthesis of long-wavelength emission CQDs was achieved in this work. Boron and nitrogen co-doped CQDs (BN-CQDs) were synthesized by one-step microwave assisted hydrothermal method with o -phenylenediamine as carbon and nitrogen source, boric acid as boron source. The BN-CQDs (QY = 13.79%) synthesized under the optimal conditions exhibit excitation independence, a large Stoke shift, satisfactory fluorescent stability, good biocompatibility and low toxicity, which can meet the basic requirements as cell imaging agent. Cell imaging measurements prove their increased intracellular accumulation with the extension of incubation time with HeLa cells, and clearly observable BN-CQDs imaging for cell morphology. Hence BN-CQDs can be used as a good cell imaging agent.

Fe-Mn based layered transition metal oxides are compelling candidates for sodium-ion cathodes owing to their high specific capacity and cost-effectiveness. However, their practical application is hampered by inherent challenges including the Jahn-Teller effect, lattice oxygen loss, transition metal dissolution. In this study, Al/Ti co-doped Na0.67Fe0.4Mn0.4Al0.1Ti0.1O2 (FM-AT) cathode is proposed and prepared. The introduction of Al/Ti, creating strong Al-O and Ti-O bonds, effectively stabilizes the lattice oxygen and elevates the reversibility of anionic redox reactions. Furthermore, the stability of the transition metal layer is effectively enhanced, suppressing transition metal dissolution and the P2-OP4 phase transition associated with TMO2 layer slippage at deep charge states. The FM-AT demonstrates excellent cycling stability, with a capacity of 137.1 mAh g-1 under 20 mA g-1 and a capacity retention of 85.5% after 50 cycles (55.7% for the pristine FM cathode). Even after 200 cycles under 200 mA g-1, a capacity retention of 72.1% is achieved (versus 20.9% for the FM). This work offers a novel method for enhancing the structural stability of iron-manganese based electrode and designing cost-effective, high-performance sodium ion cathodes.

The development of effective antibacterial surface coatings is essential for reducing the risk of implant-associated infections. Polymers with different charge characteristics, including nonionic, cationic and anionic polymers, have been widely explored for antibacterial/antifouling surface modification. However, a systematic comparison of their interactions with polydopamine (PDA) during coating formation remains limited. In this work, a series of composite coatings were fabricated via a one-step co -deposition process involving dopamine and polymers with different charge properties. The coating formation behavior, interfacial adhesion, stability, surface morphology, and antibacterial performance were systematically investigated. The results demonstrate that co -deposition with cationic polymers, particularly polyquaternary-2 (PQ), and polyhexamethylene biguanide hydrochloride (PHMB), significantly enhances the adhesion and stability of PDA coatings. Among the evaluated systems, the PDA-PQ coating exhibited pronounced antibacterial activity through contact-mediated and photothermal mechanisms while maintaining good cytocompatibility, as confirmed by both in vitro and in vivo assessments. This study elucidates the role of polymer charge in governing PDA-based coating formation and performance, providing valuable insights for the rational design of PDA-based antibacterial coatings for medical device surfaces.

To address the challenge that Cu + active species in developed Cu + -based adsorbents tend to oxidize to Cu 2+ in humid air, thereby losing their adsorption performance for carbon monoxide, in this study, methyltrimethoxysilane (MTMS) was employed as a hydrophobic modifier to modify the Cu + -based CO adsorbent. The hydrophobically modified Cu + -based CO adsorbent effectively shields the Cu + active species from water, thereby significantly inhibiting their oxidative deactivation. The successful grafting of MTMS onto the ultra-stable Y-type zeolite (USY) support was confirmed, thus markedly enhancing the hydrophobicity of the resulting Cu + -based CO adsorbent. The optimized adsorbent, CuCl(4)@USY-MTMS(24%), exhibits a high CO adsorption capacity of 2.61 mmol/g, coupled with high adsorption selectivity for CO/CO 2 and CO/N 2 . Moreover, the MTMS-modified hydrophobic CuCl(4)@USY-MTMS(24%) adsorbent exhibits significantly enhanced oxidation resistance compared to its unmodified counterpart, after aging in 70% relative humidity air for 24 h, it retains 79% of the CO adsorption capacity of pristine adsorbent, far exceeding the 47% retention of the unmodified version. This remarkable performance confirms that the hydrophobically modified adsorbent achieves stable CO separation.

CeO2is widely studied in catalysis owing to its Ce4+/Ce3+redox couple and oxygen storage capacity (OSC), but its low-temperature redox activity remains a challenge. To address this, this study investigates the effects of saturated In3+doping (1 mol.%) on the structural, redox, and catalytic properties of nano-octahedral CeO2. Structural and chemical analyses reveal that In3+doping induces lattice contraction from 5.4171 to 5.4129 Å, increases oxygen vacancy concentration from 29.7% to 39.8%, and raises surface Ce3+fraction from 27.6% to 30.0%. Consequently, H2-TPR measurements show that the surface reduction peak temperature decreases from 548 to 406 °C and the onset reduction temperature shifts from 309 °C to 183 °C. Quantitative OSC analysis further demonstrates that the low-temperature OSC increases from 13.17 to 20.57 mmol O2/mol and the high-temperature OSC from 53.36 to 59.38 mmol O2/mol upon doping. As a result of these enhancements, CO-TPSR tests reveal improved low-temperature CO oxidation performance, with the CO2light-off temperature decreasing from 99 to 72 °C and the rapid oxidation temperature from 153 to 96 °C. Notably, H2O and H2signals are detected during CO-TPSR, and FTIR analysis confirms the enrichment of surface hydroxyl groups in the doped sample, offering new mechanistic insights into the involvement of surface species in the reaction pathway. Overall, saturated In3+doping effectively enhances the oxygen vacancy concentration, surface reducibility, and CO oxidation activity of nano-octahedral CeO2.

In this study, Li x Ca 1−x W 1−0.75x Te 0.75x O 4 ceramics were synthesised using a non-stoichiometric co-doping strategy (Li/Te = 1:0.75), systematically revealing the synergistic effect of Li and Te. During doping, Li was introduced from the decomposed secondary Li 2 TeO 4 phase, which acted as a liquid-phase sintering aid. Density functional theory calculations confirmed that Te 4+ substitution for W 6+ enhanced the chemical bond strength and effectively passivated oxygen vacancies, promoting densification and improving dielectric properties. However, excessive doping led to the substantial decomposition/volatilisation of the secondary phase, where the volatilisation of Te outweighed its positive substitution effect, thereby degrading both structure and dielectric performance. Following optimisation, the Li 0.04 Ca 0.96 W 0.97 Te 0.03 O 4 ceramic sintered at 910°C exhibited optimal properties: εr = 9.86, Q× f = 89,613, τ f = −38.6 ppm/°C. The material also exhibited favorable dielectric characteristics in the terahertz range (0.2–1.2 THz, ε r : 4.97–6.36, tan δ: 0.009–0.0848), rendering it a potential candidate for dual-band applications in low-temperature co-fired ceramic technology.

Bimetallic Ru-Co nanofibers (NFs) are successfully fabricated via an electrospinning technique coupled with thermal calcination and hydrogen reduction treatment. The optimized fibrous Ru 3 -Co 7 nanozyme demonstrates exceptional peroxidase (POD)-like activity, capable of oxidizing the chromogenic substrate 3,3′,5,5′-tetramethylbenzidine (TMB) by hydrogen peroxide (H 2 O 2 ) to generate oxidized TMB (oxTMB), yielding a characteristic blue response. Capitalizing on the ascorbic acid (AA)-mediated chromogenic attenuation mechanism via oxTMB reduction, a colorimetric sensing platform is established by tracking the absorbance variations at 650 nm. This AA quantification strategy achieves superior analytical performance, featuring a detection limit (LOD) of 0.87 μM, a broad linear response spanning 1–40 μM (R 2 = 0.993), and remarkable selectivity against interfering species. Furthermore, this platform is successfully applied to assess total antioxidant capacity in real-world samples, including fresh fruit juices and available beverage. The POD-like catalytic reliability is validated through parallel validation against the established cupric reducing antioxidant capacity (CUPRAC) assay, confirming the robustness of this strategy for practical antioxidant analysis.
