Heterogeneous activation of peracetic acid (PAA) is promising for advanced water purification but still suffers from nonselective radical production, matrix interference, and inefficient electron transfer at poorly defined sites. Here, we design an asymmetric Fe–Co dual-atom catalyst (FeCo-DAC) anchored on N-doped porous carbon, effectively steering PAA activation toward a surface-confined, electron-transfer-dominated pathway. FeCo-DAC/PAA exhibits rapid bisphenol A (BPA) degradation ( k obs =1.90 min −1 ), surpassing single-metal counterparts (Fe-SAC 1.61 min −1 ; Co-SAC 0.41 min −1 ). EPR reveal O₂•⁻dominated and ¹O₂ dominated pathways on Fe‑SAC and Co‑SAC, respectively, while FeCo‑DAC indicating an interfacial electron‑transfer‑dominated mechanism. Mechanistic analyses reveal that electronically asymmetric Fe–N 4 and Co–N₃ sites cooperatively polarize adsorbed PAA to form a high-potential intermediate, enabling direct electron transfer from BPA within a closed interfacial loop with minimal radical release. The FeCo-DAC/PAA system efficiently degrades diverse micropollutants (BPA, BPS, BPC ≈ 100 %; RhB, SMX ≥96 %) and achieves robust TOC removal (52 %-63 %) in complex real-water matrices with low metal leaching (Fe²⁺ ≈ 78.4 μg/L; Co²⁺ ≈ 189.5 μg/L). Additionally, embedding FeCo-DAC into a PVDF membrane yields continuous-flow BPA removal (95 %-100 %) over 600 min, underscoring the practical potential of this asymmetric dual-site catalyst for sustainable, selective water purification.

Rational tuning electronic configuration of CoO is important for accelerating sluggish oxygen evolution reaction (OER) kinetics. This work reports a simultaneous incorporation of highly electronegative fluorine (F) and high-valence molybdenum (Mo) into CoO nanoneedles (denoted as FMo-CoO). The dual-doping strategy boosts Co 3+ content and compressive strain, which strengthens Co—O bond covalency and enables a lattice-oxygen-mediated (LOM) pathway during OER catalysis. Concurrently, the nanoneedle morphology coupled with F/Mo co-doping synergistically enhances surface properties, granting FMo-CoO exceptional superhydrophilicity and superaerophobicity. As a result, FMo-CoO achieves outstanding OER performance in alkaline media, requiring only overpotential of 287 mV at 10 mA/cm 2 . This work provides a novel method to boost the OER performance of CoO by anion and cation ions doping.

Vanadium dioxide (VO 2 ) is a promising thermochromic material for smart windows; however, its practical application is limited by a relatively high phase transition temperature ( T c ) and insufficient modulation capability in both luminous transmittance ( ) and solar energy ( ). Cation co-doping serves as an effective strategy for optimizing its thermochromic performance near room temperature. W-Ti co-doped VO 2 films were fabricated via a two-step rapid thermal processing (RTP) annealing method using vanadyl acetylacetonate as the precursor. The co-doping of W and Ti leads to an enhancement in the thermochromic performance of the VO 2 thin films. The phase transition temperature ( T c ) was reduced from 69.75 °C to 52.35 °C. By adjusting the Ti doping content, the co-doped films maintained a low Tc while improving the luminous transmittance modulation ( ) from 39.8% to 46.1% and the solar energy modulation ability ( ) from 6.3% to 9.3%. These improvements are attributed to modifications in the band structure induced by W-Ti co-doping. The enhanced thermochromic performance, compared with that of undoped VO 2 , demonstrates that W-Ti co-doping provides a promising strategy for advancing VO 2 -based smart window applications.

Polyphenylene oxide (PPO) exhibits excellent heat resistance, flame retardancy and low dielectric constant. However, the chain rigidity of PPO results in significant brittleness in its foams. In this work, PPO was blended with polyamide6 (PA6) to enhance the toughness and processability of its foams. Innovatively, maleic anhydride-grafted PPO (PPO-g-MAH) and triglycidyl isocyanurate (TGIC) were synergistically utilized as compatibilizers and to construct a crosslinked network. PPO-g-MAH served as a bridge connecting PPO and PA6, TGIC functioned as a crosslinking agent for PA6 and PPO-g-MAH, forming a long-chain entangled and crosslinked structure that interpenetrates the matrix. Supercritical CO 2 foaming was employed to prepare the PPO/PA rigid foam. At 30 phr PA6 content, the synergistic compatibilization led to a refined co-continuous phase morphology and yielded a low density of 0.203 g/cm 3 . At a density of 0.251 g/cm 3 , the average cell size was approximately 22 µm and exhibited a uniform distribution, which contributed to a high flexural strength of 47.29 MPa. Additionally, the foam demonstrated a low dielectric constant of 2.05. This research presents a viable approach for fabricating rigid foams that are lightweight, high strength, and heat-resistant. It showed significant potential for lightweight structural components in automotive engineering, and high-frequency insulating layers in construction.

Fe-based single-atom catalysts (Fe-SACs) are able to enhance the Peroxymonosulfate (PMS) activation effectively just as a result of metal active sites that are precisely defined and atomically dispersed. The Fe 2 Co 1 CN catalyst synthesized in this work exhibits excellent catalytic activity toward PMS activation: the Fe 2 Co 1 CN/PMS system achieved nearly 100% 2-chlorophenol (2-CP) removal, a sharp contrast to only ∼1.5% removal by PMS alone. Corresponding, a mineralization rate of 78.3% was attained within 2 hours, coupled with extremely low metal leaching concentrations — evidencing the Fe 2 Co 1 CN catalyst’s superior structural stability and high catalytic efficiency in PMS activation. Together with its non-radical PMS activation mechanism, these merits highlight the catalyst’s potential as an efficient, stable, and selective candidate for practical wastewater treatment applications.

Cultured meat has emerged as a promising approach to enhancing global food sustainability. Current production methods, however, rely mainly on single-cell-type culture, which fails to replicate the complex composition of conventional meat. In this study, a scaffold-free co-culture system was established to generate structured microtissue comprising highly differentiated muscle and fat cells. Co-cultured spheroids with the ratios of piscine adipose-derived stem cells (PADSCs) to piscine satellite cells (PSCs) being 5:5, 7:3 and 9:1 were investigated, and the result showed that all ratios remained robust and highly viable throughout the differentiation process and successfully induced the formation of bionic tissue containing both myotubes and adipocytes. Based on transcriptome data, the cluster analysis indicated that co-cultured spheroids (the ratio of PADSCs to PSCs was 7:3) were similar to the PADSC spheroids, and the expression levels of cell cycle-related and extracellular matrix-related genes were biased towards those of PADSC spheroids. These results indicated that these co-cultured spheroids held promise as building blocks for further tissue assembly and offered a promising approach for scaling up the production of structured cultured fish meat.

Atomic site–specific reactivity induced by the lattice distortion has garnered increasing research interest for advancing the heterogeneous catalytic conversions, owing to strain–field–tunable electronic structure of the distorted active sites. Here, we prepare the catalysts with reactive center of ferromagnetically nanoparticulate cobalt that is fully exposed by the Co(111) lattice plane with increasing strain. Such sites can boost peracetic acid (PAA) utilization under a mild magnetic field (MF, maximum 500 mT) to produce a bulk of reactive species with high ratio 93.1% R–O • for sulfamethoxazole abatement and thus attain high–effective greener decontamination for water remediations. Spin‒polarized density functional theory and experimental results collectively confirm strain–induced spin modulation at Co(111) step A sites as a critical reactivity determinant. This work integrates MF into PAA utilization and thus provides a perspective on improving the atomic economies of developing ferromagnetic nanoparticulated metal sites into water remediation in low-energy utilization route.

PLA adsorbs and releases more Cd than PVC, amplifying rumen disruption. • MPs–Cd inhibited hydrolase activity and disrupted carbon‑nitrogen metabolism. • MPs–Cd reduced fermentative taxa but promoted the growth of potential pathogens. • PLA–Cd disturbed nitrogen metabolism, while PVC–Cd impaired lipid/energy pathways. • MPs act as Cd carriers, exacerbating rumen metabolic dysfunction. Microplastics (MPs) and cadmium (Cd) both occur frequently in livestock feed and husbandry environments, and can exert adverse impacts on animal physiological homeostasis and core functional processes, particularly digestive physiology. However, the mechanisms underlying their combined effects and the roles of different MP types are not yet fully understood. Here, we employed a continuous multi-cycle in vitro rumen fermentation model to investigate the impacts of co -exposure to aged polylactic acid (PLA) and polyvinyl chloride (PVC) MPs with Cd on rumen fermentation characteristics, microbial community structure, and metabolic profiles. The results demonstrated that PLA exhibited stronger Cd adsorption and greater Cd-release efficiency compared with PVC. Co-exposure markedly inhibited hydrolytic enzymes, reduced total volatile fatty acid and gas production, and decreased fermentative taxa such as Bacteroidetes and Bacillota , while favoring potential pathogens. Non-targeted metabolomics further revealed that PLA–Cd exerted a stronger influence on nitrogen metabolism, whereas PVC–Cd caused more pronounced disturbances in lipid and energy metabolism. Microbiome–metabolite network analysis revealed a more fragmented structure under PLA–Cd treatment, indicating greater perturbation of microbial–metabolic interactions. Overall, MPs act as Cd carriers, substantially threatening ruminant health by reshaping microbial composition and fermentation metabolism. This study underscores the risks of combined MP and heavy-metal pollution and calls for re-evaluating the environmental safety of biodegradable plastics in agriculture.

Rare earth (RE) substitution is the primary way to realize the electric field-controlled magnetism in BiFeO 3 multiferroic ceramics by breaking the cycloidal spin structure to release the intrinsic weak ferromagnetism, where the electric field-induced phase transition of Pna 2 1 /R 3 c plays the key role. In the present work, the remarkable electric field-controlled magnetism has been achieved in La/Sm co-substituted BiFeO 3 multiferroic ceramics. The structure evolution in Bi 1- x (La 0.37 Sm 0.63 ) x FeO 3 ceramics is modulated from R 3 c to Pna 2 1 and finally Pbnm with increasing x . The weak ferromagnetism is released as the symmetry is tuned from R 3 c to Pna 2 1 and the cycloidal spin structure is broken. Furthermore, La/Sm co-substitution significantly suppresses the leakage current to a level far below that of other RE-substituted BiFeO 3 ceramics, thereby facilitating the enhanced dielectric strength, which significantly promotes the electric field-induced phase transition of Pna 2 1 /R 3 c , and subsequently, the remarkable electric field-controlled magnetism (a change of M r up to 62.7%) is achieved in the present ceramics. Moreover, the significant improvement in ferroelectricity is also achieved after the electric field-induced phase transition of Pna 2 1 /R 3 c .

Significant progress has been made in materials development for hydride ion (H − ) conduction and H − -mediated electrochemical devices. However, a gas-solid H − battery (g-HIB) that utilizes H 2 and metals as the active materials of the electrodes and offers the potential for high capacity and energy density has yet to be developed. Here, a typical metal-hydrogen system, Mg-H 2 , is employed to build such a g-HIB. Experimental results validate that hydrogenation and dehydrogenation of the anode lead to electric energy output and input, respectively, in the Mg|3CeH 3 @BaH 2 |H 2 developed. This g-HIB exhibits an initial capacity of 1,526 mAh/g and maintains a capacity retention of over 70% after 60 cycles. It operates effectively across a wide temperature range of −20°C to 90°C. The integration of this g-HIB with a secondary ion battery could create a novel hydrogen-electricity co-storage system that can be applied to hydrogen-electricity powertrains of fuel cell vehicles or drones to deliver a high hydrogen energy efficiency of 93.9%.

Developing ethanol-selective gas sensors remains challenging because structurally and chemically related volatile organic compounds (VOCs) often induce similar responses on semiconductor metal oxide surfaces. Here, we report a zeolitic imidazolate framework-8 (ZIF-8)-enabled strategy for reprogramming gas selectivity rather than simple response enhancement by constructing Co₃O₄@ZIF-8 core–shell nanorod arrays. The ZIF-8 layer was deposited on Co₃O₄ nanorods through a seed-assisted conversion route to regulate gas transport and interfacial adsorption. Compared with pristine Co₃O₄ sensor, ZIF-8 functionalization induced a distinct selectivity shift from acetone-preferred to ethanol-preferred sensing (8.7 toward 100 ppm ethanol at 225 °C) and improved humidity tolerance due to the hydrophobicity of ZIF-8. Density functional theory (DFT) calculations revealed stronger ethanol adsorption on ZIF-8 than acetone adsorption, supporting preferential ethanol enrichment within the ZIF-8 shell. This work establishes ZIF-8 functionalization as an effective route for engineering ethanol selectivity in Co₃O₄ sensors and provides insight into MOF-assisted selectivity reprogramming in MOS chemiresistive gas sensors.

Alkaline hydrogen evolution reaction (HER) is constrained by the Sabatier principle, making it challenging to simultaneously optimize water dissociation and hydrogen desorption. Here, we report a spatially decoupled tandem catalyst, Co(OH) 2 @Mo 2 C, that circumvents this constraint via a hydroxyl-mediated hydrogen spillover pathway. Mo 2 C serves as the *H generation site via rapid water dissociation, while adjacent Co(OH) 2 functions as the *H acceptor and recombination center, with abundant surface hydroxyl groups on Co(OH) 2 accelerating hydrogen spillover from Mo 2 C to Co(OH) 2 and sustaining water dissociation kinetics. CH 3 I poisoning experiments, corroborated by in situ Raman spectroscopy and density functional theory calculations, reveal the critical mediating role of hydroxyl groups in hydrogen migration. The optimized catalyst achieves only 43 mV overpotential to reach 10 mA cm −2 in 1 M KOH, and durability over 150 h at 0.5 A cm −2 in an anion exchange membrane water electrolyzer. This work establishes a generalizable interfacial engineering strategy to circumvent the Sabatier limitation by accelerating hydrogen migration on spatially segregating elementary steps. A spatially decoupled Co(OH) 2 @Mo 2 C tandem electrocatalyst shows that Mo 2 C rapidly dissociates water while Co(OH) 2 efficiently shuttles *H to accelerate H 2 release, where Co(OH) 2 abundant surface hydroxyl groups accelerate hydrogen spillover from Mo 2 C to Co(OH) 2 and maintain water dissociation kinetics.
