Animals integrate internal states to guide survival-critical decisions, but whether and how intestinal bacteria influence this process by interacting with host metabolic cues remains unclear. Here we show that the intestinal pathogen P. aeruginosa overrides host decision-making in fasted C. elegans by modulating central serotonin (5-HT) signaling. Fasting promotes risk-taking by activating an intestinal energy-sensing pathway that induces the chemoreceptor SRI-36 in ADF 5-HT neurons, sensitizing ADF to food odors and triggering moderate 5-HT release that drives food attraction despite risk. In contrast, intestinal P. aeruginosa reverses this strategy by activating a distinct immune-brain axis that further amplifies SRI-36 expression and ADF sensitivity, leading to excessive 5-HT release that suppresses food attraction and prioritizes safety. These findings reveal a gut-to-brain mechanism by which metabolic and immune signals converge on central 5-HT to reshape behavioral strategies.

As modern electronic systems advance toward compact architectures and intensified power densities, managing heat generation and dissipation has become a central challenge affecting both device stability and functional reliability. In this study, a carbon-coated three-dimensional (3D) porous copper foam composite (CFCC) was synthesized using a combined hydrothermal and annealing process to enhance heat dissipation. Optimization studies revealed that the combination of 6 g glucose with a 600 °C annealing treatment produced the most favorable coating quality. Consequently, the CFCC exhibited an in-plane thermal conductivity of 16.3 W m −1 K −1 and a thermal diffusivity of 28.5 mm 2 s −1 , representing 39.3% and 122.7% increases over pristine copper foam, respectively. Infrared thermography confirmed significantly improved heat spreading, with the optimized composite maintaining the lowest steady-state temperature (145.8 °C) under a constant 160 °C heat load. Microstructural and mechanistic investigations indicate that the improved heat-transfer capability originates from the higher ordering of the carbon domains, the decrease in structural defects, and the strengthened Cu–C interfacial interactions. These factors collectively reduce phonon scattering, extend the phonon mean free path, and minimize interfacial thermal resistance, enabling effective three-dimensional heat conduction. Overall, the integrated hydrothermal–annealing strategy presents a controllable, scalable, and cost-effective approach for producing high-quality carbon coatings on porous metal substrates, offering substantial promise for advanced thermal management in next-generation high-power electronic systems.

Calcium silicate hydrate (C-S-H), the principal binding phase in Portland cement, plays a critical role in the immobilization of heavy metals, yet a quantitative and mechanistic understanding of Cu 2+ uptake by C-S-H remains incomplete. This study investigates the immobilization behavior of Cu 2+ by C-S-H with systematically controlled Ca/Si ratios (0.6–1.6) and develops a thermodynamically consistent sublattice solid-solution model. The C-S-Hs were synthesized under sorption equilibrium conditions and characterized to determine their structural evolution with Ca/Si ratio. Cu 2+ sorption was subsequently examined on pre-synthesized C-S-Hs, combined with spectroscopic analyses to elucidate Cu coordination environments. The results show that Cu 2+ is immobilized predominantly through structural incorporation at low Cu 2+ loadings rather than hydroxide precipitation. With increasing Cu 2+ concentration, Cu 2+ progressively intercalates into the interlayers of C-S-H, partially replacing interlayer Ca 2+ and forming Si-O-Cu linkages associated with Q 2 silicate sites. The Ca/Si ratio strongly controls both uptake capacity and binding mechanism. High Ca/Si ratios promote silicate-chain polymerization through conversion of Q 1 to Q 2 units, whereas extremely low Ca/Si ratios induce redistribution between Q 2 and Q b 2 species. At intermediate Ca/Si ratios, Cu 2+ is mainly stabilized as hydroxyl-associated species. Once the sorption capacity is exceeded, excess Cu 2+ transforms into CuO under alkaline conditions. Based on these observations, a CASH+Cu thermodynamic model incorporating five Cu-bearing endmembers was developed and calibrated using both aqueous and solid-phase data. The model quantitatively reproduces Cu uptake, solution chemistry, and phase assemblages, providing a predictive framework for Cu 2+ retention in cementitious systems.

Catalytic pyrolysis of waste plastics to high-value olefins offers a sustainable route to address pressing global white pollution and realize plastic resource recycling, yet it faces a long-standing core dilemma limiting industrial application: low-cost calcium-based catalysts suffer from critical activity and stability defects under high-temperature conditions, while high-performance single-atom catalysts rely heavily on expensive noble or transition metals with poor industrial scalability. Notably, alkaline-earth metal single-atom catalysts remain largely underexplored for this high-temperature plastic pyrolysis application, with no mature catalytic system reported to date. Herein, we designed and fabricated a calcium single-atom catalyst with a well-defined carbon-nitrogen-calcium coordination structure through a facile synthetic strategy, to address these technical bottlenecks and enable efficient polypropylene pyrolysis for targeted olefin production. Calcium atoms are atomically dispersed and stably anchored on nitrogen-doped carbon supports via C-N bonds, fully overcoming the sintering-induced deactivation and active site loss of traditional calcium oxide-based catalysts. This catalyst exhibits an outstanding pyrolysis oil yield of 96.19 wt% with 73.82 wt% olefin selectivity; it also markedly reduces reaction activation energy, promotes selective β-scission of polymer chains, suppresses undesired byproduct formation, and retains atomic-level dispersion even after multiple cyclic reactions. This work provides a low-cost, high-efficiency catalyst for waste plastic upcycling, and lays a critical theoretical foundation for the rational design of alkaline-earth metal single-atom catalysts for high-temperature pyrolysis systems.

The development of efficient and cost-effective electrocatalysts is critical for advancing durable water-splitting systems. Special attention must be given to catalyst design, functionality, and interface regulation strategy to create synergistic effects that enhance electrocatalytic performance. We present a rational design of non-precious optimized heterojunction electrocatalysts comprising face-centered cubic nickel metal, cubic Ni₃S₄, and hexagonal NiS phases, supported on a 3D cross-linked carbon nanofiber (CNF) network. Detailed characterization reveals lattice-matching heterojunctions between Ni₃S₄, NiS, and Ni, where strong C-S bonding stabilizes the heterojunction and ensures effective electronic coupling. These heterogeneous interfaces serve as highly electroactive regions, significantly enhancing charge transfer, structural stability, and reaction kinetics. The optimized Ni₃S₄/NiS/Ni@CNF composite demonstrates exceptional bifunctional performance, achieving a low hydrogen evolution reaction overpotential of 88 mV at 10 mA/cm² with a Tafel slope of 34 mV/dec and an oxygen evolution reaction overpotential of 330 mV at 10 mA/cm² with a Tafel slope of 45 mV/dec, alongside excellent durability. The superior electrocatalytic performance is attributed to synergistic interactions at the Ni₃S₄, NiS, Ni, and CNF heterointerfaces, enhanced electronic conductivity, increased catalytic site exposure, and efficient interfacial charge transfer. This work offers a new strategy for the rational design of heterojunction-based materials with superior electrochemical performance in water-splitting applications.

Constructing vanadium oxide/metal selenide heterostructure is a promising strategy to enhance the reaction kinetics and structural stability for high-performance sodium-ion batteries (SIBs) anode. However, achieving a uniform and robust heterointerface remains challenging due to the multivalent state transformation of the V and the thermodynamic stability difference between V O and V Se bonds. Herein, we design and synthesize the V 2 O 3 /Fe 3 Se 4 @C heterostructure via a facile liquid-phase reaction followed by a seleniziation method. The unique coordination environment in a ferric vanadate and the reduction potentials difference between Fe and V cations promote the formation of a well-defined heterointerface. Density functional theory calculations confirm the formation of a built-in electric field at the heterointerface, thereby accelerating the reaction kinetics. The electric field originates from the orbital hybridization, which promotes the formation of a robust Se V O bonding configuration. Meanwhile, the carbon coating maintains structural integrity by suppressing volume expansion during cycling. These synergistic effects effectively enhance the overall structural stability of the material. Thus, the prepared V 2 O 3 /Fe 3 Se 4 @C anode exhibits exceptional electrochemical performance, delivering a high specific capacity of 378.2 mAh g −1 at 0.5 A g −1 and 308.9 mAh g −1 at 8 A g −1 , and retaining a specific capacity of 313.8 mAh g −1 after 2500 cycles at 5 A g −1 . This work establishes a new electron orbital modulation strategy for exploring high-performance vanadium oxide-based anode materials for SIBs.

Abstract Unsaturated silicon oxide (SiOx) as one of the anode materials for lithium-ion batteries (LIBs) shows relatively high specific capacity, but its overall electrochemical performances remain to be improved. Herein, a facile synthetic approach is developed to deposit SiOx and amorphous carbon on spherical graphite particles getting core–shell structured graphite@SiOx/C (SG@SiOx/C) composites via tetraethyl orthosilicate and ascorbic acid as precursors. The homogeneous and dense SiOx/C layer can improve the structural integrity of the SG@SiOx/C anodes and afford the composites with manifest specific capacity for Li+ storage. To improve the initial Coulombic efficiency (ICE), the SG@SiOx/C composites are further chemically prelithiated. The prelithiated SG@SiOx/C exhibits an initial lithiation/delithiation capacity of 632.6/629.4 mAh g–1 with a remarkable ICE of 99.5%. The reversible specific capacity can remain at 390.5 mAh g–1 after 1000 cycles at a current density of 1C. This work offers technical guidance on how to synthesize high-performance graphite@SiOx composites, providing a pathway to high-energy-density LIBs.

A novel Co 9 S 8 /PW 11 composite was synthesized with the dual-function. • The composite enabled efficient Cyt-c isolation from porcine heart, confirmed by SDS-PAGE. • Co 9 S 8 /PW 11 @Cyt-c showed enhanced peroxidase-like activity for colorimetric AA detection. A novel Co 9 S 8 /PW₁₁ composite was synthesized via a facile hydrothermal method. The composite exhibited specific adsorption toward cytochrome C (Cyt-c) at pH 10, achieving an adsorption efficiency of 92.8%. The adsorption behavior followed the Langmuir isotherm model with a maximum adsorption capacity of 209.59 mg·g −1 . The method was successfully applied to the selective isolation of Cyt-c from complex biological sample and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) confirmed that the separated protein had high purity. In addition, the resulting Co 9 S 8 /PW 11 @Cyt-c system possessed peroxidase-like activity, capable of catalyzing the oxidation of colorless 3,3′,5,5′-tetramethylbenzidine (TMB) to a colored product. Ascorbic acid was found to effectively inhibit this oxidation and decolorize the system, enabling the development of a colorimetric assay for ascorbic acid determination in food samples. Under optimized conditions, the method exhibited a good linear response in the range of 0–100 μM, with a detection limit of 0.68 μM, and demonstrated practical applicability for quantitative analysis of real food specimens. Collectively, these results demonstrate that the Co 9 S 8 /PW 11 composite serves as a versatile platform, showing outstanding performance in both the efficient purification of Cyt-c and the construction of sensitive sensing systems.

The transcription factor zinc finger protein 143 (ZNF143) plays a crucial role in regulating diverse biological processes, including cell cycle progression, development, and cellular differentiation. Similarly, c-Myc is well-established as a key regulator of cell proliferation, differentiation, and metabolic homeostasis. While studies have demonstrated ZNF143's involvement in the proliferation of both normal hepatocytes and hepatoma cells, the precise mechanisms underlying ZNF143-mediated regulation of hepatocyte proliferation, as well as its potential functional interplay with c-Myc in this process, remain to be fully elucidated. In this study, we investigated the dynamic expression patterns of ZNF143 and c-Myc during distinct phases of liver regeneration using a 2/3 partial hepatectomy (PHx) mouse model. To elucidate the regulatory roles of these factors in hepatocyte proliferation, we employed the mouse normal hepatocyte line AML12 and the human hepatoma cell line Huh7 as experimental models. Through MTT, CCK-8, EdU, quantitative real-time PCR (qRT-PCR), and Western blot, we examined the individual and combined effects of ZNF143 and c-Myc on hepatocyte proliferation. Our findings reveal that ZNF143 inhibits proliferation and cell cycle progression in AML12 cells but promotes these processes in Huh7 cells. Notably, co-overexpression (OE) of ZNF143 and c-Myc in AML12 cells inhibited proliferation and cell cycle progression, suggesting that ZNF143 exerts a dominant regulatory effect over c-Myc in normal hepatocytes. This study establishes a critical foundation for investigating the role of ZNF143 in hepatocyte proliferation in vivo, with potential implications for liver regeneration and transplantation therapies. Significance Statement The transcription factor ZNF143, which contains seven zinc finger domains, has been extensively studied in various cancers. However, its role and underlying mechanisms in liver regeneration remain largely unexplored. Here, we report the dynamic expression pattern of ZNF143 in a mouse liver regeneration model, suggesting its potential involvement in hepatocyte proliferation. Utilizing two cell lines, AML12 and Huh7, our study revealed that ZNF143 exerts opposing effects on cell proliferation and the cell cycle in normal hepatocytes versus hepatocellular carcinoma cells. Mechanistically, ZNF143 regulates these processes by suppressing c-Myc expression. Future work focused on designing targeted therapies based on the regulatory model of ZNF143 could represent a significant strategy for addressing challenges in both liver regeneration and liver disease.

Proton exchange membrane (PEM) electrolysis demands hydrogen evolution reaction (HER) cathodes that minimize precious-metal usage while remaining durable in strongly acidic media, yet improving Pt utilization and stability under reduced PGM loading remains challenging. Here, we develop a programmable nucleation pathway that uses in situ H* from formic acid (HCOOH) dehydrogenation at a Ru–Pd interface to gate reducing equivalents during nucleation. This enables site-confined Pt nucleation/immobilization and stabilizes a hydrogen-management interface for H* generation, relay, and recombination. The resulting Ru–Pd–Pt/C comprises uniformly dispersed ternary nanodomains (~2.46 nm). In 0.5 M H 2 SO 4 , Ru–Pd–Pt/C delivers η 10 = 12.24 mV, an apparent Tafel slope of 29.9 mV dec −1 from a unified 20–50 mV fitting window, and a PGM mass activity of 6.58 A mg PGM −1 at η = 50 mV. More importantly, membrane electrode assembly tests under identical assembly conditions show lower cell voltages than commercial 40 wt% Pt/C over 1–4 A cm −2 and stable operation at 1 A cm −2 . Density functional theory calculation shows Ru/Pd neighbors tune Pt toward near-thermoneutral H adsorption (ΔG H* = −0.19 eV), consistent with density of states/d-band shifts and the improved apparent HER response. This formation-stage programming offers a transferable framework for durable, low-PGM HER cathodes in acidic water electrolysis.

Aiming to improve thermal insulation and minimize heat dissipation in high-temperature industrial applications, this study fabricated mullite whisker-reinforced Al 2 O 3 -SiC-C (ASC) castables via in-situ whisker growth. Using boehmite as a pore-forming agent, AlF 3 as a catalyst, and silica sol as a binder, the composites were synthesized and characterized for mechanical properties, thermal conductivity, oxidation resistance, and slag resistance. Finite element simulations (160 μm and 10 mm models) analyzed whisker-induced pore refinement effects on heat transfer. After sintering at 1450 °C, in-situ grown mullite whiskers partitioned large pores into smaller ones, refined pore structures, and introduced abundant solid-gas interfaces. These deflected heat flux, increased path tortuosity, and elevated interfacial thermal resistance, reducing 800 °C thermal conductivity by 20.9% compared to the control sample. The material retained good mechanical strength, oxidation resistance, and slag penetration resistance. This work offers new insights for designing high-performance castables combining superior insulation with robust high-temperature performance.

Current adsorbents for bisphenol A (BPA) require complex preparation and relatively low adsorption capacities. Here, a high-performance adsorbent (Fe-N-C) was synthesized from iron-modified zeolite imidazole frameworks-8 (ZIF-8) via pyrolysis. With an exceptionally high specific surface area of 1565.15 m 2 ·g −1 , Fe-N-C removed 90% of BPA within 10 min and achieved adsorption equilibrium within 3 h. Furthermore, Fe-N-C exhibited a maximum BPA theoretical adsorption capacity of 877.45 mg·g −1 (288 K). The adsorption kinetics and isotherms conform to pseudo-second-order kinetics and the Langmuir model. Fe-N-C also demonstrated excellent performance across a wide pH range (4–10) and in complex water matrix. The high adsorption capacity was primarily attributed to π-π interactions, along with hydrogen bonding, electrostatic interactions, and hydrophobic interactions. Notably, in addition to efficiently adsorbing BPA, Fe-N-C exhibited a high selectivity toward organic compounds with two benzene rings by π-π interactions, such as bisphenol B (BPB), 2,2-bis (4-aminophenyl) propane (BAPP) and diclofenac (DCF) due to the mediation of graphitized microdomains. This study provides a simple route to prepare high-capacity N-doped carbon adsorbents for the selective and rapid adsorption of specific structural pollutants.
