Owing to their exceptional performance and well-defined structure-activity relationships, single-atom photocatalysts have garnered increasing research interest, particularly in the context of photocatalytic hydrogen peroxide (H 2 O 2 ) production. However, the reaction mechanisms of the enhanced performance, such as the hemilabile mechanism in heterogeneous catalysis, remain only partially understood. In this work, we successfully loaded Bi single atoms onto S-doped graphene nitride carbon(Bi@g-C 3 N 4-x S x ). Synchrotron radiation analysis demonstrated that the reversible breaking and formation of Bi S bonds during the reaction promote reactant adsorption and product desorption, respectively, thereby boosting the H 2 O 2 production rate to 450.6 μmol·g −1 ·h −1 . Notably, both high-throughput computational analysis and the Sabatier principle indicate that oxygen (O 2 ) adsorption and H 2 O 2 desorption compete with each other in specific coordination environments. By introducing the hemilabile mechanism, significant dynamic reorganization of the electronic structure at the active site was achieved, enabling the catalyst to circumvent the limitations predicted by conventional volcano plots, which critically depends on the complexity of the coordination environment. The experimental confirmation of the hemilabile mechanism in heterogeneous catalysis offers a new perspective for the rational design of advanced catalysts and lays the groundwork for future innovations in sustainable chemistry and industrial applications. In the single-atom catalyst, hemilabile Bi S bonds dynamically switch between enhancing O 2 adsorption and promoting H 2 O 2 desorption, thus achieving highly efficient photocatalytic hydrogen peroxide production.

A unique “Ce→W→Ni” electronic conjugation channel is constructed. • Theoretical calculations confirm an optimized electronic structure and the d -band center. • In situ Raman results reveal the formation of the “H-down” configuration. • The as-prepared Ce-Fe(Ni)WO 4 /NF exhibits an outstanding HER activity. Orbital hybridization between metal compounds can modulate the electronic structure and d -band center of catalysts to optimize the adsorption energy barriers of reaction intermediates, consequently efficiently regulating catalytic performance. Herein, a Ce and Ni co-doped iron tungstate nanosheet on nickel foam (Ce-Fe(Ni)WO 4 /NF) is rationally designed as an efficient electrocatalyst for the hydrogen evolution reaction (HER). In situ Raman results reveal that the evolution of interfacial water promotes the formation of the “H-down” configuration to expedite the Volmer process for proton generation at the interface. Theoretical calculations confirm that the Ce/Ni co-doping effectively optimizes the electronic structure and the d -band center. Specifically, a unique “Ce→W→Ni” electronic conjugation channel is constructed to regulate the spin state of Ni, and Ni and Ce act as the dual catalytically active sites for favorable intermediate adsorption (Ce for water/hydroxy adsorption and Ni for hydrogen adsorption), thereby lowering the kinetic barrier of HER. Thus, the as-prepared Ce-Fe(Ni)WO 4 /NF exhibits an outstanding HER activity with a low overpotential of 63 mV at 10 mA cm −2 and stable operation for 120 h at 250 mA cm −2 . Moreover, Ce-Fe(Ni)WO 4 /NF also possesses bifunctional catalytic activity for the urea oxidation reaction (UOR), offering a promising route toward low-energy-consumption hydrogen production. This work provides new insights and a theoretical basis for designing high-performance alkaline HER electrocatalysts via multi-element electronic conjugation.

In-situ growth of NiO nanowalls on MEMS micro-hotplates secures Ohmic contact. • Pt doped into the NiO lattice intrinsically anchors oxygen vacancies. • The device achieves exceptional 60-day stability and 98% RH moisture resistance. • Rapid and ultraselective acetone sensing enables non-invasive diabetes screening. Non-invasive breath acetone analysis offers a promising approach for continuous diabetes monitoring. However, poor long-term stability and material-electrode interfacial drift in p-type metal oxide sensors remain key bottlenecks for their clinical translation. To address these challenges, a Micro-Electro-Mechanical-System (MEMS) acetone sensor was developed via the in-situ growth of Pt-doped NiO nanowalls on a micro-heater chip. Unlike conventional surface modification and physical coating methods, the intrinsic doping of Pt within the NiO lattice and its integration with the substrate address signal drift through a synergistic dual mechanism. Specifically, the in-situ growth minimizes contact resistance drift at the material-electrode interface. Simultaneously, intrinsic Pt lattice doping anchors the active sites, suppressing catalyst thermal agglomeration and preserving structural stability at the gas-solid interface. The optimized sensor exhibits a response of 10.3 to 100 ppm acetone at 200 °C (a 5.7-fold enhancement over pure NiO) and a response time of 37 s. Furthermore, the device demonstrates continuous stability over 60 days and steady-state reliability at the 1.8 ppm clinical diagnostic threshold. It also shows stable moisture resistance (up to 98% relative humidity), maintaining typical p-type characteristics without response reversal phenomena. Supported by competitive co-adsorption density functional theory (DFT) calculations, this moisture tolerance is attributed to a favorable adsorption energy that prioritizes acetone chemisorption over water molecules. Comprehensive characterizations and DFT models indicate that Pt doping triggers localized lattice distortions and charge compensation, increasing the surface oxygen vacancy concentration (35.2%). This theoretically broadens the hole accumulation layer (HAL) and facilitates single-molecule acetone adsorption (−1.12 eV), stabilizing the p-type conduction mechanism. This work provides a stable, drift-resistant acetone sensor capable of sub-ppm trace detection for non-invasive diabetes screening.

Interfacial polarization tuning via BO x F y modification and in situ N-doped carbon • Synergistic interfacial polarization for dielectric response and impedance matching • Minimum reflection loss of −58.97 dB with a bandwidth of 4.24 GHz Pristine Ti 3 C 2 T x MXene generally suffers from severe impedance mismatch arising from its excessive electrical conductivity, which fundamentally limits efficient electromagnetic wave (EMW) attenuation. Herein, an interfacial modulation strategy is proposed by integrating fluorinated boron oxide (BO x F y ) nanophases and in situ derived N-doped carbon into a Ti 3 C 2 T x MXene framework through a hydrothermal process. Distinct from conventional boron-containing modification, the introduced BO x F y species provide abundant polarization-active sites and tailor the local interfacial environment through the coexistence of B O and B F coordination, thereby improving dielectric polarization and impedance matching. Meanwhile, the in situ formed N-doped carbon establishes defect-rich conductive networks, enabling balanced conductive loss and dipolar polarization. More importantly, the synergistic coupling among BO x F y nanophases, N-doped carbon, and Ti 3 C 2 T x MXene constructs abundant heterogeneous interfaces and multiscale conductive pathways, facilitating interfacial polarization and electromagnetic energy dissipation. As a result, the optimized BN(1:1)-MXene achieves a minimum reflection loss of −58.97 dB at 1.77 mm and an effective absorption bandwidth of 4.24 GHz. Furthermore, radar cross-section simulations demonstrate remarkable electromagnetic scattering suppression with a maximum reduction of 32.05 dB m 2 at normal incidence. This work highlights the synergistic effects of interfacial modulation on electromagnetic attenuation, offering a promising strategy for high-performance MXene-based EMW absorbers.

Ce–O v coupling enables site-differentiated mixed AEM/LOM pathways. • CeCoFe-LDH delivers 230 m V at 10 mA cm −2 and a low Tafel slope of 27.9 mV dec −1 . • Controlled lattice oxygen redox suppresses Co/Fe dissolution and deep surface reconstruction. • CeCoFe-LDH operates stably for 1500 h at 500 mA cm −2 under industrial conditions. • Anion-exchange-membrane water electrolysis reaches 1.71 V at 1 A cm −2 for 220 h at 60 °C. Achieving both high OER activity and long-term stability at industrial current densities remains a key challenge for green hydrogen production by water electrolysis. Herein, we report a CeCoFe-layered double hydroxide (LDH) catalyst designed to balance lattice oxygen activation with structural stability under industrial-current-density OER conditions. The synergistic interaction between doped Ce and synthesis-induced oxygen vacancies (O v ) preferentially activates adjacent lattice oxygen sites, thereby introducing a lattice oxygen mechanism (LOM) channel while retaining partial metal-site adsorbate evolution mechanism (AEM) activity. As a result, the catalyst delivers an overpotential of 230 m V at 10 mA cm −2 and a Tafel slope of 27.9 mV dec −1 , demonstrating excellent OER performance. When assembled as the anode catalyst in an anion exchange membrane water electrolyzer, CeCoFe-LDH achieves a cell voltage of only 1.71 V at 1 A cm −2 and 60 °C, with stable operation for 220 h. Experimental characterization and theoretical calculations reveal that Ce-O v coupling upshifts the O 2 p band center while moderately weakening the Co O bonds, thereby facilitating controlled lattice oxygen redox participation. Meanwhile, residual AEM activity on Co sites, together with Ce-mediated structural stabilization, prevents excessive lattice oxygen consumption and suppresses Co/Fe dissolution and deep surface reconstruction, allowing stable OER operation for 1500 h at 500 mA cm −2 . These findings highlight a rational strategy for durable high-performance OER electrocatalysts for industrial applications.

Chemotherapy-induced intestinal mucositis is a common and clinically important adverse effect. However, its underlying mechanisms remain poorly understood and effective interventions are limited. This study investigated the protective effects of a cell-free L. rhamnosus -fermented cereal fraction against 5-fluorouracil (5-FU) induced CIIM in a murine model. L. rhamnosus fermentation markedly enhanced the functional value of the cereal matrix by enriching soluble fermentation-derived bioactives, including TCA-soluble peptide content, total phenolic and flavonoid content, and lactic acid. Prophylactic administration of the fermented cereal fraction attenuated 5-FU-induced mucosal injury, enhanced intestinal antioxidant capacity, improved mucosal architecture and barrier-related indices, and suppressed epithelial apoptosis. Exploratory quantitative proteomic analysis identified candidate proteins whose abundance was altered following 5-FU treatment, including proteins associated with antioxidant defense, apoptosis, cytoskeletal organization, and epithelial barrier-related processes. In contrast, fermented cereal intervention restored the expression of key endogenous antioxidant and barrier-associated proteins. Notably, the final pH-matched lactic acid control indicated that low final pH and the direct presence of lactic acid were insufficient to account for the protective effects of the fermented cereal fraction, suggesting that multiple fermentation derived components contributed to the observed bioactivity. Collectively, these findings indicate that L. rhamnosus -fermented cereal mitigates CIIM through fermentation-enhanced exogenous antioxidant delivery, support of endogenous antioxidant defenses, and attenuation of mucosal and barrier-related alterations. This study supports the potential of cereal fermentation-derived bioactives as functional dietary ingredients for managing CIIM.

Wet Fe(II)EDTA complexation is a promising technology for NO removal, but its practical application is severely hindered by O 2 -induced oxidation of Fe(II)EDTA and inefficient regeneration of Fe(II)EDTA–NO. Herein, an oxygen-vacancy-rich BiOCl/g-C 3 N 4 S-scheme heterojunction with interfacial Bi–O–C covalent bonds was constructed for oxygen-resistant photocatalytic–complexation denitrification. Structural characterizations and density functional theory calculations confirmed that Bi–O–C bonds served as atomic-level charge-transfer channels, strengthening interfacial coupling and promoting directional S-scheme charge separation. This configuration preserved strongly reductive electrons on g-C 3 N 4 for the reduction of Fe( III )EDTA and Fe(II)EDTA–NO, while retaining oxidative holes on BiOCl. Meanwhile, oxygen vacancies on BiOCl acted as preferential O 2 adsorption and activation sites, converting O 2 into ·O 2 − and thereby transforming O 2 from a competitive oxidant into an electron-buffering species that suppresses BiOCl photocorrosion and regulates interfacial redox cycling. The optimized 20BCN–Fe( II )EDTA system achieved an average NO removal efficiency of 88.92% under 14% O 2 and maintained above 80.02% efficiency after 30 cycles. Product analysis revealed a reduction-dominated NO conversion pathway, with NH 4 + and N 2 as the major reduced nitrogen products, a total reduced-product selectivity of 91.9%, and a nitrogen recovery of 94.4%. Kinetic analysis confirmed that NO absorption proceeded in a fast reaction regime enhanced by interfacial redox reactions. This work provides an atomic-level strategy for designing oxygen-resistant photocatalytic systems for wet denitrification under realistic flue-gas conditions.

Developing bifunctional electrocatalysts with high activity and long term durability remains challenging for overall water splitting, mainly due to sluggish reaction kinetics and structural instability under high current densities. Herein, an oxygen vacancy rich RuCoFe-LDH electrocatalyst with low Ru content was successfully fabricated on nickel foam through a one step hydrothermal method. TMAOH inhibition, pH dependent analyses, and isotope labeling DEMS measurements collectively reveal that the synergistic coupling between Ru doping and oxygen vacancies promotes lattice oxygen participation and activates the LOM pathway during OER. Benefiting from the optimized electronic structure, RuCoFe-LDH/NF requires overpotentials of only 212 and 131 mV to reach 10 mA cm −2 for OER and HER, respectively, with corresponding Tafel slopes of 30.7 and 61.7 mV dec −1 . Moreover, the RuCoFe-LDH based electrolyzer achieves 100 mA cm −2 at a cell voltage of only 1.75 V and maintains stable operation for 1000 h during both OER and HER, and the corresponding full electrolyzer also operates stably for 1000 h at 100 mA cm −2 . This work provides an effective strategy for designing high performance LDH based bifunctional electrocatalysts through low content Ru incorporation and oxygen vacancy engineering.

Natural fiber reinforced polylactic acid (NF/PLA) composites are attractive sustainable materials, yet their broader engineering use is limited by weak interphase load transfer and rapid, dripping combustion. A lignin migration driven interphase phosphorylation strategy was proposed to construct a continuous phosphate-rich interphase on reed fibers, enabling simultaneous reinforcement and flame retardancy in PLA. A mild and efficient solvent activation step induces in- situ lignin deposition and generates a reactive, adhesive fiber surface, followed by aqueous phosphorylation to covalently introduce phosphate functionalities. Crucially, this strategy preserves the intrinsic structural integrity of the macroscopic fibers while simultaneously tailoring the interface for enhanced adhesion and flame retardancy. As a result, the reconstructed interphase strengthens fiber matrix adhesion and promotes condensed phase charring while improving melt resistance to dripping. At a 30 wt% modified fiber loading, the composite reaches a limiting oxygen index of 33.0% and achieves a UL-94 V-0 rating with no cotton ignition. Cone calorimetry shows 38% and 27% reductions in peak heat release rate and total heat release relative to neat PLA. Meanwhile, tensile strength increases by about 15% and notched impact toughness by about 270%, evidencing effective load transfer. The lignin enriched, phosphate functionalized interphase synchronizes rapid melt stabilization with the formation of a compact protective char, thereby reconciling reinforcement with fire safety. This scalable interphase-engineering strategy offers a sustainable route to high performance PLA composites for transportation, electronics, packaging, and related applications.

Lithium−sulfur (Li−S) batteries are regarded as one of the most promising next-generation energy-storage systems owing to their ultrahigh theoretical energy density and the natural abundance of sulfur. However, their practical application is severely hindered by the intrinsically low electrical conductivity of sulfur, sluggish conversion kinetics of lithium polysulfides (LiPSs), and the shuttle effect of LiPSs. To address these challenges, we constructed a three-dimensional (3D) MXene/CNT−Co composite cathode host that integrates strong adsorption with efficient catalysis. The interconnected 3D MXene/CNT conductive framework effectively mitigates the restacking of MXene and establishes continuous electron/ion transport pathways. Meanwhile, the introduced Co provides highly active catalytic sites that markedly accelerate the reversible conversion of LiPSs, enhance chemical adsorption, and suppress polysulfide shuttling. Benefiting from the synergistic regulation of structure and catalysis, the S@MXene/CNT−Co electrode delivers promising electrochemical performance, exhibiting an initial specific capacity of 877.8 mAh g−1 at 1.0 C and retaining 381.2 mAh g−1 after 1000 cycles, corresponding to a capacity retention of 43.4 % and a capacity decay rate of 0.057 % per cycle. In addition, S@MXene/CNT−Co shows excellent rate capability, delivering 443.8 mAh g−1 at 2.0 C, which corresponds to 77.6 % of the initial capacity at 0.2 C. This work provides a viable strategy and rewarding perspective for designing high-performance MXene-based cathode materials for Li−S batteries.

Regulating the local coordination environment of active sites is an effective strategy to enhance the intrinsic activity of layered double hydroxides (LDHs) for the oxygen evolution reaction (OER). Here we report a controlled postsynthesis Fe incorporation approach that uses NiAl-LDH as a structurally robust host to construct NiAl(a)-Fe(e)-LDH with distorted local Fe coordination environments through alkali treatment and ultrasonic assistance. The resulting catalyst exhibits superior OER performance compared to counterparts with similar Fe content, highlighting the critical role of Fe coordination. Solid-state NMR and X-ray absorption fine structure reveal that ultrasonic-assisted Fe incorporation induces Fe–O lattice distortion and modifies the local electronic states of Fe. Density functional theory calculations show that these distorted environments upshift the d-band center and lower the *OOH formation energy barrier, thereby accelerating OER kinetics. This work establishes a direct correlation between local Fe coordination, electronic structure, and catalytic activity and provides a general strategy for active-site engineering in LDH-based OER electrocatalysts.

Developing gas sensors that achieve high sensitivity, a low detection limit, and superior selectivity continues to be a critical challenge for the detection of acetone in exhaled breath. Metal oxide semiconductors (MOS) are extensively utilized in chemiresistive gas sensors, largely because of their distinguished gas sensing performance and tunable physicochemical properties. However, unmodified MOS nanostructures are prone to aggregation and lack an effective mechanism for efficient charge separation, thus exhibiting the features of limited specific surface area, low porosity, and sluggish charge migration rate, which deteriorates gas sensing performance. In this study, we employed the impregnation method and sacrificial template method to prepare a three-dimensional inverse opal (3DIO) WO 3 composite loaded with graphitic carbon nitride (g-C 3 N 4 ). This composite shows outstanding acetone sensing capability. Specifically, it achieves a response of 7.33 at 10 ppm, a detection limit of 65 ppb, favorable selectivity, and reliable stability. Such superior sensing behavior benefits greatly from the synergistic effect of abundant active sites endowed by its unique 3D ordered macroporous structure and accelerated interfacial charge transfer from the n-n heterojunction formed between WO 3 and g-C 3 N 4 . Consequently, the construction of WO 3 /g-C 3 N 4 composites with a three-dimensional ordered macroporous architecture offers a promising strategy for real-time and accurate acetone detection, as well as for the development of portable breath analysis sensors.
