A novel water-soluble AIE luminogen (TPE-phos) enabled enzyme-triggered fluorescence turn-on. • Dual visual/spectrofluorometric readout sensing platform combined AIE and conventional ELISA. • Etomidate was detected at 3.52 ng/mL with excellent linearity (R 2 = 0.9916). • Excellent specificity, <5% variation at 24h, and applicability to forensic testingof small molecules. Concealed drug abuse and delayed detection hinder global drug control efforts, necessitating rapid, on-site point-of-care detection methods. Here, we report a sensitive and practical aggregation-induced emission (AIE)-ELISA method for the quantitative detection of etomidate (ETO)—an emerging drug of abuse—in biological matrices. A water-soluble tetraphenylethylene derivative, TPE-phos, was designed and synthesized as an efficient alkaline phosphatase (ALP) substrate. In the competitive ELISA format, ALP-catalyzed hydrolysis of TPE-phos generates the poorly water-soluble TPE-OH, which spontaneously aggregates and produces strong fluorescence enhancement, enabling sensitive signal readout. The method exhibits a linear range of 0–125 ng/mL (R 2 = 0.9916) and a limit of detection of 3.52 ng/mL. Satisfactory spike recoveries were obtained in artificial urine and saliva, confirming robustness in complex biological matrices. The proposed method offers a compelling balance of sensitivity, operational simplicity, and cost-effectiveness, making it a practical tool for point-of-care ETO screening in public safety and forensic contexts.

This work reports the preparation of N/S co-doped titanium dioxide (N/S-TiO 2 ) via in-situ sulfur doping assisted by alkaline hydrolysis followed by subsequent nitrogen doping and the lithium storage application. TiCl 4 is used as the titanium source, and sodium sulfide (Na 2 S) solution provides the alkaline hydrolysis environment and sulfur source, thus enabling the synthesis of S doped anatase TiO 2 (S-TiO 2 ). Urea is applied as the nitrogen source under high-temperature annealing, resulting in N/S co-doped anatase TiO 2 (N/S-TiO 2 ) materials. In addition, oxygen vacancies, which might enhance the electronic/ionic conductivity, is created. Consequently, N/S-TiO 2 (10:1) exhibits excellent rate performance (85.6 mAh g − 1 at 20 C) and long-term cycling stability (116.22 mAh g − 1 after 1500 cycles at 3 C). Further analysis using cyclic voltammetry (CV), galvanostatic intermittent titration technique (GITT), and electrochemical impedance spectroscopy (EIS) shows an enhanced pseudocapacitive contribution, increased lithium-ion diffusion coefficient, and reduced charge transfer resistance. These findings provide new insights for developing high-performance, structurally tunable metal oxide anode materials.

Oxygen vacancies are a key factor determining the efficiency of the CO2hydrogenation reaction and play a crucial role in CO2adsorption and activation. However, effectively regulating the concentration of oxygen vacancies to enhance the performance of the light-driven reverse water gas shift (RWGS) reaction remains a challenge. To address this, this study successfully developed Pt/TiO2catalysts with varying oxygen vacancy concentrations by controlling the morphology of TiO2. Structural characterization results indicate that, compared to Pt/TiO2-NR, Pt/TiO2-NB exhibits a higher oxygen vacancy (OV) concentration and greater CO2absorption. Catalytic performance evaluation results showed that under an irradiance of 2.5 W/cm2, the CO production rates of the Pt/TiO2-NB catalyst reached 57.03 mol·gPt−1·h−1. Furthermore, the catalyst maintained excellent catalytic stability during 45 h of continuous operation, demonstrating good potential for practical applications.

Photocatalytic treatment of wastewater is often limited by insufficient light penetration caused by pollutants and inefficient catalyst recovery. To address these challenges, a novel dual-channel photocatalytic reactor (DCPR) based on an α-Fe₂O₃/TiO₂ film was developed. In this system, light propagates through an independent transparent channel, while pollutants and oxygen flow through a separated reaction channel, enabling enhanced light utilization and improved interaction between reactants and photocatalytic interfaces. The results demonstrate that the dual-channel configuration significantly enhances photocatalytic performance. The degradation rate of methylene blue was 3.65 times higher than that of a conventional single-channel reactor. Under optimized conditions, the phenol degradation efficiency reached 93.05% after 12 h of visible-light irradiation, accompanied by a total organic carbon (TOC) removal efficiency of 71.3%. The α-Fe₂O₃/TiO₂ catalyst film exhibited excellent reusability, maintaining approximately 90% of its degradation efficiency after ten consecutive cycles. Furthermore, the practical applicability of the DCPR system was evaluated using a synthetic industrial wastewater matrix containing phenol, humic acid, and inorganic salts. The reactor maintained continuous degradation capability under this complex wastewater condition, demonstrating its potential for practical wastewater treatment applications. Mechanistic investigations revealed that superoxide radicals (·O₂⁻) and photogenerated holes (h⁺) were the dominant reactive species involved in the degradation process, while hydroxyl radicals (·OH) played a secondary role. The enhanced photocatalytic performance was attributed to the separation of light and pollutant transport pathways, which effectively reduced light attenuation and promoted mass transfer. This study provides an effective reactor design strategy for improving photocatalytic efficiency and offers a promising approach for the treatment of complex wastewater matrices.

Cerium-doped carbon dots (Ce-CDs) were prepared via a facile one-pot hydrothermal method. • Ce-CDs demonstrated potent SOD-like activity and total antioxidant capacity. • Ce-CDs can act as an effective nanozyme for mitigating oxidative damage in seeds. Developing stable and cost-effective nanozymes as alternatives to natural superoxide dismutase (SOD) remains a significant challenge. Herein, we report the rational design and one-pot hydrothermal synthesis of cerium-doped carbon dots (Ce-CDs) as highly efficient SOD-mimetic nanozymes. The as-prepared Ce-CDs were monodisperse spherical nanoparticles (average diameter: 2.26 nm) possessing abundant surface functional groups and a high quantum yield of 46%. XPS analysis confirmed a characteristic Ce 3 + /Ce 4+ mixed-valence state, where the predominance of active Ce 3+ species (71.8%) facilitated a potent redox cycle for O 2 •- scavenging, analogous to the catalytic center of native SOD. EPR spin-trapping experiments further confirmed that Ce-CDs effectively scavenge O 2 •- , providing direct evidence for the proposed redox cycle mechanism. The Ce-CDs exhibited robust SOD-like activity and total antioxidant capacity, as evidenced by NBT and ABTS assays, maintaining high stability over varying pH and ionic strengths. When integrated into biological systems, these nanozymes effectively rejuvenate aged soybean seeds by scavenging 58.23% of O 2 •- and regulating endogenous ROS homeostasis. This work not only provides a high-performance fluorescent nanozyme with a well-defined catalytic mechanism but also demonstrates its potential for mitigating oxidative damage in seed preservation.

Functional ceramic foams are promising candidate materials that integrate electromagnetic absorption, load-bearing, thermal insulation, and thermal stability, to meet the challenges of extreme environments in modern aerospace technology. In this study, SiC fiber has been introduced in the ZrC-TiC ceramic foam to enhance the mechanical properties and electromagnetic wave absorption performance. The SiC f /ZrC-TiC ceramic foam has been fabricated by a simple precursor self-foaming method with a porosity of 76.9% and a density of 0.31 g/cm 3 . The interconnection of SiC fibers endows SiC f /ZrC-TiC ceramic foam with excellent load-bearing capacity with a compressive strength of 41.3 MPa. Meanwhile, the introduction of SiC fiber boost its electromagnetic wave absorption performance with a RL min = −63.5 dB and EAB max = 6.04 GHz. The high porosity endows it with a low thermal conductivity advantage of 0.231 W·m −1 ·K −1 . Particularly, SiC f /ZrC-TiC ceramic foam exhibit outstanding high-temperature stability. After 10 thermal cycles at 1600 °C, the compressive strength remained at 30.7 MPa, and the EAB max was 5.28 GHz (RL min = −57.2 dB). The multifunctional synergistic advantages of SiC f /ZrC-TiC ceramic foams provide a feasible strategy for the design of multifunctional protective materials in aerospace.

This study addresses the urgent demand for simple and sensitive online gas monitoring technologies in the field of environmental safety by developing a high-performance cataluminescence (CTL) sensor based on oxygen-vacancy-rich microporous titanium dioxide (Ovm-TiO 2 ) for detecting trace isobutyraldehyde (IBL). The Ovm-TiO 2 material, synthesized via a two-step heating process combined with a KBH 4 treatment, features abundant oxygen vacancy defects on its surface, which are pivotal to enhancing sensor performance. Density functional theory (DFT) calculations unravel the surface-mediated mechanism, the oxygen vacancies serve as active sites, drastically enhancing the chemical adsorption and activation of O 2 on the Ovm-TiO 2 surface, which is the key to boosting the cataluminescence efficiency. The developed sensor exhibits outstanding detection performance for IBL, with a wide linear range (0.0100–5.00 mg/L, R 2 = 0.9997), a low detection limit (3 μg/L), and achieved recovery rates of 87.6%–107% with good reproducibility (relative standard deviation, RSD: 5.3%–9.0%) in practical sample analysis. This work not only provides a viable online monitoring solution for IBL but also elucidates the CTL enhancement mechanism at the atomic level, offering important theoretical foundations and practical insights for designing highly sensitive gas sensors.

Quasi-one-dimensional (quasi-1D) van der Waals MX 3 transition metal trichalcogenides (TMTCs), have emerged as a compelling material platform due to their unique quantum confinement effects and anisotropic properties. Nevertheless, the narrow growth window and extreme sensitivity to growth parameters make it challenging to synthesize TMTCs via chemical vapor deposition (CVD). Herein, we demonstrate an ethanol-assisted CVD method for the scalable growth of TiS 3 nanoribbons. This approach utilizes the combination of ethanol with TiCl 4 and S powder to form a Ti source precursor, enabling the high yields of TiS 3 nanoribbons with a thickness as low as 10 nm and lengths on the micrometer scale (140±30 µm, aspect ratio of approximately 260). Moreover, the nanoribbons exhibit epitaxial vertical alignment on substrates, facilitating the versatile transfer to arbitrary target substrates. The single TiS 3 nanoribbon exhibits high conductivity (σ 293 K = 3.1 × 10 4 S/m) from 80 to 593 K. Flexible strain sensors based on TiS 3 nanoribbon networks demonstrate a high gauge factor of 135.3, a wide strain detection range (40–7400 με), and strong tolerance to temperatures up to 773 K. This strategy provides a unique pathway for synthesis of TMTCs, providing essential material support for the development of high-performance flexible electronic devices.

Technetium-99 (99Tc) predominately exists in the form of oxygenated anions (99TcO4–) under oxic conditions, which are highly soluble and non/weakly complexing; converting it to a sparingly soluble 99TcO2·nH2O precipitate for further disposal is a well-established tactic. Oxygen vacancy (OV) engineering paves a shortcut for modulating the kinetics, energetics, and mechanisms of photocatalytic reduction synergistically. However, the mechanism that OVs contribute to the photocatalytic reduction of 99TcO4– remains unclear. Herein, OV-enriched ultrathin two-dimensional TiO2 is fabricated via the solvent-free confined synthesis strategy. Based on the characterization analysis with experiments and density functional theory, it is demonstrated that the apparent elevated ReO4– (a nonradioactive surrogate for 99TcO4–) conversion efficiency is directly dependent on the content of OVs, which allows for the rapid photocatalytic reduction of Re(VII). Significantly, under simulated sunlight irradiation at pH = 2, 2D TiO2-500 °C reduced to 97.0% Re(VII) (20 mg/L) within 180 min. A reducing radical (·CO2–)-mediated pathway was proposed to account for the high-efficiency reduction of Re(VII) to Re(IV). During Re(VII) photoreduction, OVs can not only promote the adsorption of reactants but also effectively reduce the conversion barrier for the reducing radicals (·CO2–), providing a convenient channel for the rapid reduction of Re(VII). This study reveals the mechanism of OVs during the photoreductive transformation of Tc(VII)/Re(VII) comprehensively.

Titanium-based metal oxide anodes exhibit strong application potential in chlorine evolution antifouling systems from seawater electrolysis. Conventional dimensionally stable anodes (DSA) rely primarily on Ru- and Ir-based noble metal coatings, yet their large-scale industrial application is hindered by high costs and poor chlorine production efficiency. To overcome the aforementioned shortcomings, Co is introduced into the RuIrTiOx/Ti system, adopting a preparation process involving oxalic acid pretreatment and multi-step coating to fabricate RuIrCoTiOx/Ti electrodes. XRD and TEM results indicate a solid solution coating with uniformly dispersed elements formed on the electrode. The RuIrCoTiOx/Ti electrode demonstrates superior catalytic activity and nearly 84.4% faraday efficiency derived from the chlorine evolution compared to binary or ternary metal oxide-coated counterparts. Remarkably, the electrode maintains over 98.1% of its initial activity after 200 hours of continuous electrolysis. While the slightly reduced durability of RuIrCoTiOx/Ti compared to RuIrTiOx/Ti may be caused by an increased specific surface area of the mixed oxide coating and the formation of higher valence states of Ru species after Co incorporation, as evidenced by SEM and XPS results. This study provides an effective design strategy for developing low-cost, high efficiency DSA electrodes, offering promising prospects for industrial application.

Perovskite oxide photoanodes are attractive for alkaline water oxidation but are commonly limited by interfacial recombination and sluggish charge transfer. Here we enhance anisotropic SrTiO3(STO) photoelectrodes via Al doping by simple yet effective one-step hydrothermal method and identify an optimal composition at 4% Al. In 0.1 M NaOH (pH 13) under simulated AM 1.5G illumination, 4% Al:STO exhibits 2 times enhancement in photocurrent density and 80% increase in electrochemically active surface area compared with the pristine SrTiO3, as evidenced by the reduced charge-transfer resistance and enlarged light–dark photocurrent gap. together with a markedly reduced interfacial impedance, indicating accelerated charge extraction and transfer. Band-structure analysis shows a positive shift in flat-band potential and slight band-gap narrowing after Al doping, providing more favorable carrier energetics. Steady-state and time-resolved photoluminescence further demonstrate strong PL quenching and a prolonged carrier lifetime for 4% Al:STO. ECSA analysis suggests increased electrochemically accessible surface sites at the optimal doping level. Overall, moderate Al doping synergistically tunes defects, band energetics, and interfacial kinetics to improve STO photoanodes for solar water splitting.

MgH 2 was renowned for its exceptional gravimetric hydrogen storage capacity of 7.6 wt%. Nevertheless, its large-scale deployment has been limited by its sluggish kinetics. In this work, nano-sized bimetallic hydride TiVH was easily synthesized through a one-step mechanochemical method, and the synthesized TiVH remarkably improved the hydrogen storage properties of MgH 2 . The hydrogen desorption temperature of MgH 2 + 10 wt% TiVH composite was reduced to 195 °C, while the hydrogen absorption temperature was close to room temperature. Remarkably, the composite exhibited the release of 6.12 wt% hydrogen in merely 180 s under 310 °C, and rapidly absorbed 5.1 wt% H 2 within 100 s at 110 °C. The activation energies for hydrogen desorption and absorption of MgH 2 were reduced by 26% (142.6 kJ·mol −1 to 105.6 kJ·mol −1 ) and 39% (82.6 kJ·mol −1 to 50.5 kJ·mol −1 ), respectively, indicating a substantial improvement of MgH 2 in the hydrogen desorption and absorption kinetics. Furthermore, the composite displayed excellent cycling stability, retaining a high hydrogen storage capacity even after 30 consecutive cycles at 300 °C. These performance enhancements were attributed to the “hydrogen pump” effect, while the lattice distortion within bimetallic TiVH also effectively improved the hydrogen sorption kinetics of MgH 2 . This work provided a novel strategy for the construction of multi-component hydride nanocatalysts in enhancing the hydrogen storage property of MgH 2 and understanding the catalytic mechanism of these catalysts.
