Ni-phyllosilicate hard-templating yields sintering-resistant mesoporous Ni–C catalysts. • Achieves high-loading, ultrafine Ni NPs via a confined interfacial layer. • Enhanced SMSI and anti-leaching stability are confirmed by multi-technique analysis. • Superior LA-to-GVL hydrogenation: 99.7% conversion, 99.3% selectivity. • A general design for high-performance non-noble metal-carbon hydrogenation catalysts. Carbon-encapsulated metal catalysts prepared by in-situ carbonization generally suffer from severe metal sintering during high-temperature treatment. Herein, we develop a nickel phyllosilicate-assisted hard-templating strategy to construct mesoporous Ni–C catalysts with ultrafine, high-loading Ni nanoparticles partially embedded in the carbon support. A Ni 3 Si 2 O 5 (OH) 4 interfacial layer is pre-formed via ammonia evaporation prior to carbonization, which effectively inhibits Ni sintering and strengthens the metal-support interaction. The embedded structure generates charge-polarized Ni δ+ –Ni δ– sites that promote hydrogen dissociation and spillover, and enable synergistic activation of levulinic acid and H 2 . Under mild conditions (S/C = 50, 160 °C, 1 MPa H 2 ), the optimized Ni–C–p catalyst achieves 99.7% LA conversion and 99.3% γ-valerolactone selectivity within 2 h, with a reaction rate approximately three times that of conventional impregnated Ni/C. This strategy exhibits good universality for designing other non-noble metal-carbon composites toward challenging liquid-phase hydrogenation reactions.

Fabricating electromagnetic coupling carbon-based aerogels with tightly bound and uniformly distributed components is a proven strategy for improving electromagnetic wave absorption (EWA) performance. Herein, highly ordered porous cobalt/cobalt (II) oxide/carbon (Co/CoO/C) aerogels were successfully fabricated via ice-templated freeze casting coupled with one-step carbonization, relying on the complexation reaction between cobalt ions and chitosan. The optimal sample, Co/CoO/C-1.0, achieves a minimum reflection loss (RL m ᵢ n ) of −58.15 dB and an effective absorption bandwidth (EAB) of 6.48 GHz at a thickness of 2.2 mm. Additionally, the aerogel exhibits excellent radar stealth performance (with a significant reduction in radar cross-section, RCS) and thermal insulation properties. Gradient structural design effectively extends the effective absorption bandwidth (EAB) to 11.23 GHz. Mechanism analysis reveals that the outstanding EWA performance of these aerogels stems from the synergistic effect of diverse attenuation pathways, including multiple scattering, dipole polarization, interfacial polarization, conduction loss and magnetic resonance. The regulation of cobalt content effectively achieves an optimal balance between impedance matching and electromagnetic loss. This multifunctional Co/CoO/C aerogel integrating EWA, radar stealth and thermal insulation capabilities possess great application prospects under complex service conditions and provide critical guidance for the rational design of carbon-based EWA absorbers. The highly ordered porous electromagnetic coupling Co/CoO/C aerogel was synthesized. The optimized aerogel achieves a minimum reflection loss (RL m ᵢ n ) of −58.15 dB and an effective absorption bandwidth (EAB) of 6.48 GHz at a thickness of 2.2 mm. The gradient multilayer structural design effectively broadens the effective absorption bandwidth (EAB) to 11.23 GHz. Download: Download high-res image (393KB) Download: Download full-size image

Two novel microwave dielectric ceramics, AgLnMo 2 O 8 (Ln = Sm, Yb), with low permittivity and sintering temperatures, were successfully obtained through the traditional solid-phase synthesis method. XRD analysis coupled with Rietveld refinement confirmed that the as-obtained sample possesses a single-phase tetragonal scheelite-type crystal structure with space group I 4 1 / a . The superior microwave dielectric responses were secured at 825 °C for AgSmMo 2 O 8 ( ε r = 11.74, Q × f = 89,000 GHz, τ f = −47.44 ppm/°C) and 800 °C for AgYbMo 2 O 8 ( ε r = 13.29, Q × f = 73,000 GHz, τ f = −36.54 ppm/°C). Bond valence and Raman analyses demonstrate that Ag + is locally compressed whereas Ln 3+ is underbonded (rattling) at shared dodecahedral sites. The compressed Ag + contributes to the negative τ f values, whereas the smaller Yb 3+ exhibits a more intense rattling effect than Sm 3+ , causing a higher permittivity, elevated loss, and a positive τ f shift. Both ceramics exhibited excellent chemical compatibility with silver-based electrodes, with no new phases observed during co-firing. A cylindrical dielectric resonator antenna was simulated with a resonance frequency of 4.067 GHz and a bandwidth of 289 MHz, using the AgSmMo 2 O 8 ceramic material. The outstanding performance suggests that AgLnMo 2 O 8 (Ln = Sm, Yb) ceramics may be promising candidates for LTCC technologies and C-band antennas.

The vanadium disulfide (VS 2 ) possesses great potential as an excellent zinc-ion energy storage material due to low diffusion barrier and reversible redox activity. However, its high-rate zinc-ion storage capability is limited by nanosheet restacking, structural fragility, and vanadium dissolution. Herein, a synergistic strategy integrating oxygen-induced coordination reinforcement with C–N structural and conductive network reinforcement is proposed to realize thermodynamic-kinetic stabilization of VS 2 cathodes. The incorporation of oxygen converts unstable V–S bonds into a stronger, more ordered V–O coordination, reconstructing the ligand field and stabilizing the vanadium valence state, which effectively inhibits dissolution. Concurrently, the polydopamine (PDA)-derived C–N provides stable anchoring sites to immobilize vanadium species, while CNT frameworks build efficient electron/ion transport pathways and buffer volume strain. The DFT calculations and synchrotron analyses verify the ligand-field reconstruction and vanadium stabilization mechanism. Consequently, the VS 2 /V 2 O 3 -NC/MWCNTs-C (denoted as VSO-NC/MWCNTs-C) delivers a high capacity of 358.89 mA h g −1 at 0.5 A g −1 , excellent rate capability of 242.22 mA h g −1 at 10 A g −1 , along with a high energy/power density of 388.64 Wh kg −1 /1000 W kg −1 , maintaining excellent stability over 6000 cycles at 10 A g −1 . This work offers an atomic-level coordination engineering strategy for advanced V-based cathodes for zinc-ion energy storage. The VSO-NC/MWCNTs-C cathode exhibits stable structural integrity, accelerated Zn 2+ transport, and significantly suppressed vanadium dissolution, delivering high capacity, fast kinetics, and long-life cycling for next-generation zinc-ion energy storage.

The surface of the C shell is covered with mesoporous channels, which promotes the occurrence of the confinement effect. • The abundant hydroxyl groups enable the C shell not only to exert physical adsorption but also to cooperate with chemical adsorption. • Both the dual transition metal regulation mechanism and the electron cooperative mechanism can be applied in ODS. • The desulfurization rate (99.53%) can be achieved under the mild reaction condition with less dosages of catalysts and ILs. • EPR analysis and radical scavenging assay experiments confirmed that one type of free radicals acts in the ODS. Common transition metal catalysts have been widely applied in catalytic reaction. However, the shortcomings in electronic regulation mechanism, confinement effect, and synergistic adsorption remain to be urgently addressed. This study designed a dual-transition-metal-based catalyst (Mo-W@C) with a surface rich in hydroxyl functional groups. Its bimetallic active components are obtained through protonation reaction. The C shell is coated on the bimetallic active components through self-assembly and directional anchoring. These procedures reduce the interatomic distance between Mo and W in the bimetallic active component, enhancing the electronic interaction between them. The confinement effect of the C shell accelerates the collision of reaction molecules. Furthermore, the abundant hydroxyl groups on the surface of the C shell facilitate the rapid adsorption of H 2 O 2 . A high sulfur removal rate of Mo-W@C (99.56 %) was achieved under mild reaction conditions (V(ILs) = 0.1 mL, m(catalyst) = 10 mg, V(H 2 O 2 ) = 0.15 mL, 80 °C, 90 min). Moreover, the catalyst still maintained a high desulfurization rate (95.76 %) after seven cycles. The catalytic reaction mechanism involving peroxide state and electronic synergy was elucidated by experiments and analyses (XPS, EPR, etc.). This catalytic structure provides a new perspective for the research on supported catalysts. Download: Download high-res image (151KB) Download: Download full-size image

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.

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.

Phase relationships in the Yb 2 O 3 –Al 2 O 3 –SiO 2 system are critical for the design and corrosion protection of environmental barrier coatings (EBCs), the available data remain scarce and primarily limited to studies from the 1990s. The isothermal phase diagram of the Yb 2 O 3 –Al 2 O 3 –SiO 2 system at 1600°C was conducted using a classical high-temperature equilibrium quenching technique, followed by XRD, SEM, and EPMA phase analysis. The data were reported in the form of liquidus projections and an isothermal phase diagram at 1600°C, with one single-phase region, six two-phase regions, and seven three-phase regions. A comparison of the liquid phase regions at 1550°C and 1600°C revealed a systematic expansion with increasing temperature, consistent with thermodynamic expectations. The experimental results from the present work are essential for the development of a thermodynamic database for rare earth oxides, providing vital guidance for designing next-generation EBCs.

Photocatalytic oxidation of toluene to valuable benzaldehyde offers a promising pathway for sustainable production of fine chemicals and pharmaceuticals. In this process, photogenerated holes play a crucial role in C(sp 3 )-H bond dissociation. However, the photocatalytic performance of current photocatalysts is often hindered by the low separation and transfer efficiency of photogenerated charges. In this work, we presented a perovskite-based heterostructure via in situ growth of defective WO 3- x nanosheets on Cs 2 AgBiBr 6 nanoparticles for photocatalytic toluene transformation. In situ Fourier transform infrared spectroscopy tests proved the introduction of oxygen-deficient WO 3- x component enhanced the chemisorption of molecular oxygen. The in situ electron paramagnetic resonance and 4-chloro-7-nitro-1,2,3-benzoxadiazole fluorescence measurements further confirmed the presence of oxygen vacancies, and the formation of heterostructure synergistically accelerated the formation of the superoxide radicals and the transfer of photogenerated charge carriers. Under visible light irradiation, Cs 2 AgBiBr 6 /WO 3- x photocatalyst could effectively oxidize toluene toward benzaldehyde with a conversion rate of 9020 μmol g −1 h −1 , which was a 3.5-fold increase over that of the unmodified Cs 2 AgBiBr 6 .
