Layered P2-type sodium manganese oxide has emerged as a promising cathode candidate for sodium-ion batteries due to its appealing cost-effectiveness and high discharge voltage. However, its practical capacity within the voltage range of 2.0–4.0 V (vs Na+/Na) is relatively low, and its rate capability is hampered by the adverse charge/vacancy ordering during charge/discharge. In this study, a layered P′2/P3 mixed-phase Na0.8-aMn0.675Ni0.225Li0.1O2–x cathode with high (003) crystal plane intensity was designed by introducing oxygen vacancies to P2-structured materials. Aided by these advantages, the hybrid cathode material demonstrates impressive structural and thermal stability and faster Na-ion diffusion kinetics compared to a regular P2 material. Half-cell shows an initial discharge capacity retention of 101 mA h/g at 12 mA/g and 92.25% retention after 500 cycles at 120 mA/g. In combination with a hard carbon anode, the 0.5 A h pouch cell achieved a prevailing capacity retention of 95.2% after 2600 cycles at 36 mA/g. This work opens new dimensions for layered cathode materials with the aim of achieving superior cyclabilities.

Direct ammonia borane fuel cells (DABFCs) offer promising portable energy solutions but face limitations from sluggish anodic kinetics and electrode degradation. This study introduces a three-dimensional hierarchical Pd-integrated nanostructured electrode (Pd-INE) synergizing nanostructuring with interfacial engineering. Vertically oriented Pd-decorated nanosheets are electronically coupled to nickel foam (NF) via Ni(OH) 2 , maximizing active site accessibility and structural stability. Density functional theory (DFT) confirms 1.18 e − transfer from Pd to Ni(OH) 2 generates electron-deficient Pd sites that weaken NH 3 BH 3 adsorption (ΔE ads = −0.92 eV) while enabling bifunctional catalysis: Pd activates B H bonds and Ni(OH) 2 -derived interfacial hydroxyls drive B O formation. Pd-INE demonstrates superior ammonia borane oxidation activity versus conventional polymer-bound Pd/NF while achieving a record peak power density of 724.1 mW cm −2 at 80 °C in DABFC operation, 2.3 times higher than both Pd/NF (321.2 mW cm −2 ) and prior benchmarks (315 mW cm −2 ). This enhancement stems from vertical nanosheets enhancing mass/charge transport and DFT-validated electronic interactions optimizing intermediate adsorption energies. The anode exhibits exceptional durability with 35 μV h −1 voltage decay over 40 h, outperforming polymer-bound anodes by 150-fold. This work establishes an ionomer-free anode paradigm resolving activity-durability trade-offs in direct liquid fuel cells through atomically tailored bifunctional interfaces.

11β-Hydroxysteroid dehydrogenase type 2 (11β-HSD2), a key enzyme in glucocorticoid inactivation, is expressed in human and rat placentas and kidneys. However, the inhibitory effects of alkyl (C1-C20) pyridinium quaternary ammonium disinfectants (PYRs) on 11β-HSD2 remain unexplored. This study evaluated PYRs through inhibitory potency assays, mechanistic investigations, structure-activity relationship (SAR)/3D-QSAR modeling, and molecular docking using human and rat 11β-HSD2 enzymes. Human 11β-HSD2 inhibition by PYRs followed a distinct V-shaped trend: potency increased from C12 to C16 (IC 50 : C12 = 132.81 μM, C14 = 19.62 μM, C16 = 1.96 μM) but declined beyond C16 (C18 = 14.45 μM, C20 = 100.76 μM). Shorter-chain PYRs (C1-C8) were inactive at ≤100 μM. Rat 11β-HSD2 exhibited a similar inhibition pattern. SPR analysis revealed that C16 displayed the highest binding affinity ( KD = 1.98 μM) with human 11β-HSD2. Mechanistic analysis revealed mixed/noncompetitive inhibition, with PYRs binding both the free enzyme and enzyme-substrate complex. In BeWo cells, C12-C20 PYRs inhibited cortisol metabolism at 10-100 μM, whereas C16 was effective at ≥1 μM. Molecular docking indicated PYRs interact with the NAD + binding site in both species. SAR analysis identified lipophilicity, steric bulk, and flexibility as critical inhibitory determinants, with higher values enhancing potency. A 3D-QSAR pharmacophore model confirmed hydrophobic interactions as essential for inhibition. Notably, species-specific binding differences suggest caution when extrapolating rodent data to humans. These findings highlight the endocrine-disrupting potential of PYRs, demonstrating their structure- and species-dependent interference with cortisol metabolism, with implications for chemical safety assessment.

Di(2-ethylhexyl) phthalate (DEHP) is a widespread organic pollutant in aquatic environments, which possesses reproductive toxicity and endocrine-disrupting effects. Conventional detection methods often rely on bulky instrumentation, incur high costs, and require complex sample preparation, limiting their suitability for rapid or on-site analysis. Therefore, we developed a molecularly imprinted electrochemical electrode sensor using a hybrid platform of gold nanoparticles (AuNPs) and multi-walled carbon nanotubes (MWCNTs) for the sensitive and convenient detection of DEHP. The sensor was constructed by co-modifying a boron-doped diamond (BDD) electrode with MWCNTs and AuNPs, followed by the in situ electrochemical polymerization of a DEHP-specific molecularly imprinted polymer layer. The resulting electrode exhibited excellent electrochemical activity and selective molecular recognition. Electrochemical impedance spectroscopy and frequency response analysis were used to characterize charge transfer resistance and interfacial capacitance over a DEHP concentration range of 1–50 ppm. In addition, principal component analysis was applied to explore the relationship between interfacial electrical parameters and sensing behaviors. Validation with real samples confirmed the sensor’s capability to detect DEHP across varying concentrations. Therefore, the molecularly imprinted AuNPs/MWCNTs/BDD electrode sensor demonstrates high sensitivity, excellent selectivity, and operational simplicity, offering a promising strategy for the on-site monitoring of small-molecule environmental contaminants.

A collection of oxyapatite-structured Ba 2 La 3 (SiO 4 ) 2 (PO 4 )O doped with varying amounts of Tb 3+ ions (denoted as BLSPO: x Tb 3+ ) was prepared via the high-temperature solid-state reaction. The study comprehensively explored the crystalline characteristics, photoluminescence behaviors, and potential applications in LED devices. The XRD results confirmed its phase purity. Photoluminescence and excitation spectra analyses revealed that the optimal excitation wavelength for BLSPO: x Tb 3+ phosphors is 378 nm. Under this excitation, four sharp emission peaks were observed at 491 nm ( 5 D 4 → 7 F 6 ), 546 nm ( 5 D 4 → 7 F 5 ), 591 nm ( 5 D 4 → 7 F 4 ), and 626 nm ( 5 D 4 → 7 F 3 ). The best luminescent performance was achieved when the Tb 3+ ion doping concentration was 10 mol%. The concentration quenching mechanism can be effectively explained by dipole–dipole interactions. Additionally, the thermal stability of two samples, BLSPO:10 mol%Tb 3+ and BLSPO:20 mol%Tb 3+ , was tested. The results indicated an anomalous thermal quenching behavior, where the luminescence intensity increased with temperature rather than decreased. Specifically, the luminescence intensity of the BLSPO:10 mol%Tb 3+ sample increased to 112% of its initial value at 480 K, while that of the BLSPO:20 mol%Tb 3+ sample reached 111% at the same temperature, demonstrating exceptional thermal stability. When BLSPO:10 mol% Tb 3+ samples were used to fabricate green and white LEDs, their CIE chromaticity coordinates were (0.369, 0.512) and (0.323, 0.342), respectively, falling within the green and white regions of the chromaticity diagram. This demonstrates the material’s broad application prospects in LED lighting and display technologies.

Precious metals play an indispensable role in the ongoing development of fuel cells. Controlling the amount of nobel metal added while enhancing catalytic activity and durability is of critical importance. Here, we had successfully proposed a method that utilized the synergistic effects of Pt-based nanoparticles and CeNC to enhance ORR performance. Due to the presence of CeNC, the dispersion of Pt-based nanoparticles was improved, and enabled the particle size to be reduced (2-3 nm). The prepared Pt 2 Ce alloy nanoparticles exhibited an icosahedral structure. The Pt 2 Ce/CeNC-600 exhibited excellent performance in acidic electrolyte, with a halfwave potential (E 1/2 ) measured at 0.81 V. When Pt 2 Ce/CeNC-600 was applied to zincair batteries (ZABs), it could achieve a power density of 184 mW cm -2 during discharge.Theoretical calculations showed that electrons transfer from CeNC to Pt 2 Ce in Pt 2 Ce/CeNC-600, indicating the existence of electron interactions and superior charge transfer ability. In addition, the energy barrier overcome in the O 2 *→OOH* reaction was reduced because of the coexistence of Pt 2 Ce and CeNC, making it easier for the reactants to reach the transition state and significantly accelerating the reaction rate. This research provided a clear path for structural control of advanced electrochemical materials.

Electrocatalytic seawater splitting holds immense promise as a green hydrogen production technology; however, the anodic oxygen evolution reaction (OER) confronts formidable challenges arising from the high concentration of chloride ions (Cl -) and other impurities in seawater. Herein, we develop a facile two-step immersion corrosion strategy to successfully construct a Ni 3 S 2 @FeOOH heterojunction electrocatalyst on nickel foam (NF) tailored for industrial alkaline seawater oxidation. Integrating density functional theory (DFT) calculations and experimental characterizations, we demonstrate that Ni 3 S 2 @FeOOH selectively enriches OH -while repelling Cl -during OER in alkaline seawater electrolytes. Notably, in situ leaching of SO 4 2-from the electrode triggers efficient self-reconstruction, facilitating the generation of high-valence metal active sites. The asfabricated catalyst exhibits remarkable OER performance with a low overpotential of 390.5 mV at an ultrahigh current density of 1000 mA cm -2 in alkaline seawater. Moreover, it maintains exceptional electrochemical stability for over 1000 hours at the industrial current density of 1000 mA cm -2 . This work provides a scalable strategy for constructing self-reconstructing electrocatalysts that promote highvalence metal site formation and efficient Cl -repulsion in alkaline seawater oxidation.

The electro-deoxidation behavior of a solid NEU-2 lunar regolith simulant cathode was investigated in a LiCl-KCl-Li 2 O molten salt at 600°C. The process proceeds through the sequential reduction of its major oxide components: iron oxides are preferentially reduced to metallic Fe within 20 min, followed by the formation of Fe-Si and Al-Si intermetallic compounds as electrolysis continues. After 6 h, the product stabilizes into a mixture of metallic Fe and aluminum-silicon alloys, with further electrolysis driving the transformation toward Al-rich phases. The electro-reduction front advances inward with time, leading to a distinct three-layer structure in the final cathode product: a fully deoxygenated outer shell consisting of Al-Si alloy, Fe-Si alloy, and metallic Fe; an intermediate layer with high oxygen content (∼58.2 wt%) containing intermediates such as Li 2 SiO 3 and LiAlSiO 4 ; and an inner core of unreacted oxides resembling the original regolith. This study demonstrates the extraction of metals and oxygen from lunar regolith via molten-salt electrolysis at 600°C, confirming the feasibility of using the FFC Cambridge process for space metallurgy under these thermal conditions. It also uncovers the evolution pattern of the cathodic product over 12 hours, providing a temporal reference for tailoring the final products and opening up new possibilities for the efficient utilization of complex, low-grade ores.

Fe- and Cu-based catalysts are top candidates for the oxygen/hydrogen-evolution reactions, but their large-scale application is limited by rapid degradation under prolonged operation, especially at high current densities and high temperatures. Herein, a FeOOH/Cu(OH) 2 nanotube array grown on copper foil was designed for overall water-splitting. The structure enhances the electrochemical surface area, increases catalytic site density, and accelerates gas transport. DFT calculations confirms the Cu(OH) 2 and FeOOH synergy weakens HO–H bond, optimizing the ∗H adsorption energy, and driving reaction kinetics. In 1 M KOH, it achieves HER overpotentials of only 89 and 244 mV, and OER overpotentials of 124 and 424 mV at 10 and 100 mA cm −2 , respectively. Under industrial conditions (30% KOH, 65 °C), it sustains >2 A cm −2 for 100 h with negligible HER activity loss. This work provides a practical guide for designing high-activity, ultra-stable ampere-level water-splitting catalysts.

Electrocatalytic 5-hydroxymethylfurfural oxidation (HMFOR) is a sustainable route for biomass valorization to 2,5-furandicarboxylic acid (FDCA), yet balancing the competitive adsorption of HMF and OH− at the electrode−electrolyte interface is pivotal for boosting catalytic activity and selectivity. Herein, we report a terephthalic acid (PTA) modification strategy to tailor Cu-Ni(OH)2 with tunable metal valence and controllable surface charge, fabricating positively charged Cu-Ni(OH)2 and negatively charged Cu-Ni(OH)2-PTA. PTA functionalization elevates the Ni oxidation state and reinforces HMF adsorption on the catalyst surface. In situ surface-enhanced Raman spectroscopy and electrochemical impedance spectroscopy confirm that the negatively charged surface of Cu-Ni(OH)2-PTA efficiently mitigates the steric hindrance of hydrated ions and preserves a fully hydrated Cs+ interfacial microenvironment. This synergy optimizes the adsorption equilibrium of HMF and OH− via efficient and persistent HMF capture, enabling continuous enhancement of HMFOR activity. Consequently, Cu-Ni(OH)2-PTA delivers superior HMFOR performance in CsOH electrolyte, including a high FDCA Faradaic efficiency (98.2%), large current density, excellent cycling stability over 10 cycles, and stable operation for 120 h in a membrane electrode assembly (MEA) system. Notably, a high FDCA Faradaic efficiency of ∼86% is retained even in a pH 13 electrolyte with 1 M Cs+. This work elucidates the coupled effects of metal valence, surface charge, cation hydration, and interfacial water structure on HMFOR, providing a universal interfacial engineering principle for designing advanced electrocatalysts for efficient biomass electrooxidation.

Mass transfer performance is an important design criterion for the absorption of CO 2 by amines in packed columns. In this paper, the effects of diethylenetriamine (DETA)–1-dimethylamino-2-propanol (1DMA2P)–H 2 O biphasic solvent on the total mass transfer coefficient ( K G a v ) of different operating parameters (liquid flow rate, gas flow rate, liquid temperature, CO 2 partial pressure, and CO 2 loading) were investigated in a mesh-structured (DX) packed column. The mass transfer mechanism of this biphasic solvent to capture CO 2 was assessed by determining the control step of mass transfer. In addition, the experimental data were compared with two empirical models, the Sheng model and the modification, and the results showed that the modification could better fit the experimental results. Further analysis was conducted on the differences in packed column design among several different amine systems and the DETA–1DMA2P–H 2 O system. The findings revealed that the DETA–1DMA2P–H 2 O system required the least column volume, highlighting its strong potential for industrial application.
