Li/Te co-doped CaWO 4 ceramics with Li:Te molar ratios of 1:0.5, 1:0.75 and 1:1 was prepared to examine composition- and processing-dependent structural evolution and microwave dielectric properties. The Li:Te = 1:1 series was optimized at 890 °C, whereas the Li:Te = 1:0.5 and 1:0.75 series were optimized at 910 °C. XRD and Rietveld refinement, Raman spectroscopy, EPR, XPS, GCIB depth-profile XPS, ICP-OES and electron microscopy were used to correlate phase assemblage, local bonding, chemical-state signals, retained Li, microstructure and dielectric response. Under the respective optimized conditions, the Li:Te = 1:0.75, x = 0.04 ceramic exhibited the highest Q× f value of 89,613 GHz, while the Li:Te = 1:1, x = 0.04 ceramic showed the least negative τf value of −32.06 ppm/°C. GCIB depth-profile XPS revealed composition-dependent depth evolution of the relative Te 4 + - and Te 6+ -related signals, and ICP-OES confirmed systematic differences in total retained Li. In the Li:Te = 1:1 series, electron microscopy identified a Te/O-enriched amorphous interfacial region. Together, these results show that the Li:Te ratio and sintering condition jointly influence local structure, densification behaviour and microwave dielectric properties. The work provides a basis for optimizing the balance between low dielectric loss and temperature stability in CaWO 4 -based ceramics. Furthermore, a preliminary Ag co-firing test further indicates chemical compatibility under the tested condition.

Synergistic co-fermentation enhanced antioxidant capacity of C. aurantium juice. • Co-fermentation increased β-glucosidase activity and flavonoid accumulation. • Probiotic co-fermentation reshaped aroma profiles and volatile composition. • Co-fermentation promoted volatile and non-volatile metabolic remodeling. • Co-fermentation enriched flavone and flavonol biosynthesis pathway. Citrus aurantium L. ( Citrus aurantium ) is rich in flavonoids and bioactive phytochemicals, but its industrial utilization is limited by suboptimal flavor quality and instability during processing. Herein, monoculture fermentation using Lactiplantibacillus plantarum (a lactic acid bacterium) or Bifidobacterium animalis subsp. lactis (a lactic acid bacterium), together with their synergistic co-fermentation, was employed to investigate flavor and functional modifications in C. aurantium juice. Compared with monoculture fermentation, co-fermentation increased total flavonoid and phenolic contents by 23.7-50.4% and 43.6-65.0%, respectively, while β-glucosidase activity, ABTS and DPPH radical-scavenging activities increased by 10.9-27.3%, 12.6-24.4%, and 12.7-26.4%, respectively. Electronic-nose and headspace solid-phase microextraction-gas chromatography-mass spectrometry analyses revealed that co-fermentation generated a distinct volatile profile characterized by enrichment of aroma-related compounds and altered representation of compounds associated with earthy and camphor-like notes. Untargeted metabolomics revealed extensive remodeling of phenolic, amino acid, and lipid metabolism. The relative abundance of limonin showed a marginal, non-significant decrease of 3.9%, while indoline and L-tyrosine increased by 3.9% and 3.8%, respectively ( p < 0.001). These changes were accompanied by significant enrichment of the flavone and flavonol biosynthesis pathway ( p = 0.0082). Correlation analysis further revealed strong associations between key differential metabolites and functional indicators. Collectively, these findings demonstrate that synergistic probiotic co-fermentation drives metabolic remodeling and flavonoid biotransformation in C. aurantium juice, providing a promising strategy for developing high-value functional citrus beverages. Future studies should further evaluate sensory acceptability, storage stability and industrial feasibility to facilitate commercial application.

The 18-electron Ti 0.75 NiSb compound exhibits intrinsically low lattice thermal conductivity due to the presence of numerous Ti vacancies. However, the high carrier concentration limits further improvement of the thermoelectric performance. In this work, Co atoms are employed to substitute Ni atoms in Ti 0.75 Ni 1- x Co x Sb. The results show that Co substitution effectively tunes the valence electron count of Ti 0.75 NiSb and leads to the formation of a NiSb-based metallic impurity phase, which significantly reduces the carrier concentration from 8.04 × 10 21 cm −3 to 2.31 × 10 21 cm −3 . Consequently, the Seebeck coefficient increases significantly from −94 μV/K for the x = 0 sample to −189 μV/K for x = 0.5, while the electronic thermal conductivity drops substantially from 3.52 to 0.87 W/mK at 873 K. Meanwhile, the lattice thermal conductivity increases due to the reduced Ti vacancy concentration (to satisfy the 18-valence-electron rule) and the formation of the metallic impurity phases. Ultimately, a peak zT of ∼0.50 is achieved at 873 K, representing a ∼47% enhancement compared with the Ti 0.75 NiSb alloy. This work demonstrates that the combination of valence electron count modulation and interface engineering is an effective strategy to optimize the thermoelectric performance of half-Heusler systems.

Interfacial Ag° content of Ag-CeO 2 catalysts was modulated by pyrolysis temperature. • Rich Ag 0 catalysts had higher catalytic ability than those rich in Ce 3+ and defects. • Temperature triggered electron transfer of Ag 0 to carbonate-activated CeO 2 interface. • Dynamic evolution of Ag-CeO 2 interface determined catalytic capacity of its catalyst. Ag-CeO 2 catalysts were fabricated with an agar-assisted pyrolysis method and their interfacial structures were tuned to investigate their role in CO oxidation. The catalysts mainly consisted of irregular CeO 2 nanoparticles with abundant metallic Ag 0 , Ce 3+ and oxygen vacancies at the interface. As the pyrolysis temperature increased, the metallic Ag⁰ content decreased while Ag⁺ and Ce³⁺ species increased. Using CO oxidation as a probe reaction, catalytic evaluation confirmed that the activity was positively correlated with the interfacial metallic Ag⁰ content, whereas no direct positive correlation was observed with Ag⁺, Ce³⁺, or oxygen vacancies alone-suggesting a dominant role of Ag⁰, although a possible synergistic contribution from Ce³⁺/oxygen vacancies is not ruled out. Ag-CeO 2 catalysts after CO adsorption were monitored by XPS and in situ FT-IR for identifying the dynamic evolution of Ag-CeO 2 interface. The reaction temperature was revealed to trigger electron transfer from metallic Ag⁰ to the carbonate-bound CeO₂ interface, which simultaneously converted initially formed polydentate and bidentate carbonates into bridging and monodentate intermediates. The reversible redox transformation (Ag⁰ + Ce⁴⁺ ⇌ Ag⁺ + Ce³⁺) at the interface of these catalysts further corroborated the essential role of Ag⁰ in enhancing the catalytic activities for CO oxidation. These findings, obtained with CO oxidation as a model reaction, differ from the simple traditional correlations with oxygen vacancies or Ce³⁺ concentration, offering a molecular-level blueprint for designing highly active and stable CeO₂-supported catalysts for catalytic oxidation reactions.

Conventional white light-emitting diodes often suffer from low color rendering index and high correlated color temperature due to the lack of red emission. Here, we report novel rare-earth-free Cs 2 CdCl 4 : Sb 3+ , Mn 2+ phosphors synthesized via a cost-effective co-precipitation route. The dual-emission behavior arises from Sb 3+ -related self-trapped excitons (green) and the characteristic 4 T 1 (G)→ 6 A 1 (S) transition of Mn 2+ (orange). Spectroscopic and time-resolved studies reveal an efficient Sb 3+ →Mn 2+ energy transfer process, governed by a dipole-quadrupole interaction. By adjusting Mn 2+ concentration, tunable emission spanning green to orange is achieved, enabling single-component white light generation. In addition, the strong concentration and excitation-dependent emission characteristics suggest potential applications in areas such as multidimensional information encryption and optical anti-counterfeiting. This work provides a low-cost, rare-earth-free strategy for designing multifunctional phosphors for high-quality lighting and security technologies.

In photocatalytic hydrogenation, non-directional transfer of electrons and indiscriminate oxidation of products by holes often result in severe electron–hole recombination and unintended product degradation, limiting overall efficiency. Herein, we engineer both the substrate reduction and product oxidation pathways through an interface–pore co-confinement strategy, exemplified by a rationally designed covalent organic framework (COF)-bridged core–shell photocatalyst (U@TpBpy-Rh) and photocatalytic NADH synthesis. The resultant U@TpBpy-Rh functions through dual mechanisms: (1) the confined S-scheme heterojunction interface facilitates directional electron transfer from MOF core to Rh sites in COF, significantly enhancing the photocatalytic NADH synthesis with productivity of 2.82 mmol g −1 h −1 ; (2) the confined pores of the COF shell restrict NADH diffusion toward highly oxidative MOF regions, reducing its oxidation degradation by 63% compared to U@TpBpy. This work demonstrates simultaneous spatiotemporal management of competitive photocatalytic reduction and oxidation pathways and will offer a general strategy for optimizing other redox-coupled reactions.

Improving drug loading and dissolution of poorly water-soluble active pharmaceutical ingredients (APIs) remains a major challenge in formulation development. Here, we integrate atomic force microscopy (AFM) adhesion-force profiling with supercritical antisolvent fluidized-bed (SAS-FB) technology to establish a predictive framework for drug–carrier selection. Enzalutamide (ENZ), a highly crystalline and poorly soluble biopharmaceutics classification system (BCS) Class II compound, was used as a stringent model drug. Single-particle force spectroscopy measurements quantified nanoscale interaction forces between SAS-processed ENZ microcrystals and seven carrier materials. Among these, lactose T70 exhibited the highest adhesion force, which strongly correlated with its superior encapsulation efficiency (EE = 92.7 %) under identical SAS-FB processing conditions. Statistical analysis revealed a robust linear relationship between mean adhesion force and EE (R² = 0.94453), identifying adhesion force as a quantitative predictor of drug deposition efficiency. This predictive capability was further validated using three additional model compounds (naringenin, dihydromyricetin, and luteolin). Comprehensive physicochemical characterization (SEM, PSD, EDS, DSC, XRD, FT-IR, and ¹H NMR) confirmed effective deposition of ENZ onto lactose T70, particle-size reduction, preserved chemical integrity, and SAS-induced polymorphic transformation. The optimized ENZ@SAS-FB(T70) formulation achieved a 5.5-fold increase in dissolution compared with unprocessed ENZ, attributed to uniform coating, enhanced wetting, and improved dispersion of micronized drug on the carrier surface. Collectively, this study establishes AFM-guided carrier screening as a mechanistic and efficient strategy for optimizing SAS-FB formulations. By linking nanoscale adhesion forces to macroscopic encapsulation outcomes, this framework offers a generalizable approach for accelerating the development of high-performance formulations for poorly soluble APIs.

In order to enhance the actuation performance of photoresponsive hydrogels in view of their slow response rate and limited functionality, a photoresponsive hydrogel was prepared in this study. The hydrogel was constructed with a thermo-responsive poly(N-isopropylacrylamide-co-acrylamide) (P(NIPAM-AM)) matrix cross-linked by chitosan (CS) and incorporated a photothermal conversion component based on the Fe3+/tannic acid (TA) complex. We characterized the hydrogel’s microscopic morphology and measured its water absorption/desorption rates, mechanical properties, temperature sensitivity, photothermal conversion ability, actuation performance, and sensing performance. Results show that adding chitosan and acrylamide together produced a more tightly cross-linked structure. This improved the hydrogel’s mechanical strength, water retention, and actuation performance. Key performance values include a maximum stress of 101 kPa, maximum strain of 100%, and maximum bending angle of 104.8°. The hydrogel achieved a fast actuation response time of 0.732 s, a bending rate of 0.22 mm/s, and a conductivity of 1.154 (Ω·m)−1. It also demonstrated efficient photothermal conversion, NIR-responsive actuation, and conductive sensing performance. This work provides a useful strategy for developing high-performance light-responsive smart materials and a practical solution for multifunctional flexible actuators.

The precise design of a high-entropy cathode material can achieve excellent performance. Many scholars have conducted extensive research on element design, but studies on the roles of each element are relatively scarce in high-entropy systems. In this project, we adjusted the composition of Cu/Co elements and developed three materials, NaNi0.25Fe0.15Mn0.3Ti0.1Ce0.02Co0.09Li0.1O2 (HEO-Co), NaNi0.25Fe0.15Mn0.3Ti0.1Ce0.02Cu0.06Co0.05Li0.1O2 (HEO-CC), and NaNi0.25Fe0.15Mn0.3Ti0.1Ce0.02Cu0.13Li0.11O2 (HEO-Cu). The physical properties and electrochemical performances are analyzed. The appropriate introduction of the Cu element can reduce the voltage difference between the redox potential and the electrochemical polarization. Moreover, it possesses outstanding air and structural stability. The appropriate proportion of the Co element can expand the interlayer spacing of the Na layer, increase the diffusion coefficient of Na+, and achieve excellent rate performance. The appropriate ratio of Cu and Co combines the advantages of both elements, endowing cathode materials with a stable structure, excellent air stability, and electrochemical performance. This work thoroughly explores the specific roles of Cu and Co elements, providing valuable insights for the design of high-entropy cathode materials and a practical pathway toward industrial-scale applications.

Developing high-capacity cathode prelithiation agents remains challenging due to severe kinetic limitations, high operational voltages, or insufficient stability in conventional materials. To address this, we report a cobalt-decorated lithium fluoride composite (S-LiF/Co, with a Co content of 15.76 wt% by ICP-OES) synthesized via a scalable solid-state route. The in situ formed LiF/Co heterointerface serves as a catalytic center, which, as evidenced by theoretical calculations, effectively weakens Li F bonds and significantly lowers the energy barriers for both Li + migration and LiF decomposition. This enables S-LiF/Co to deliver a high initial charge capacity of 886.23 mAh g −1 . When incorporated into NCM811 cathodes, it substantially promotes a stable, LiF-rich cathode electrolyte interphase (CEI). In NCM811||Si/C full cells, this additive effectively compensates for irreversible lithium loss, yielding a high initial energy density of 484.01 Wh kg −1 and superior cycling stability with 80.42% capacity retention after 170 cycles. This work provides an effective interface-engineering strategy to overcome the intrinsic barriers of LiF-based materials, offering a promising prelithiation solution for next-generation high-energy-density batteries.

Although Co modulation can optimize the electronic structure of Pt for hydrogen evolution reaction (HER), PtCo still suffers from chloride ion (Cl–) corrosion in seawater electrolysis, severely limiting its practical applications. This study successfully constructed P-doped PtCo nanoflowers (P-PtCo NFs) with excellent corrosion resistance and rapid water dissociation kinetics through the introduction of P for synergistic electronic regulation. To demonstrate, the P-PtCo NFs require only an 18.2 mV overpotential to achieve 10 mA cm–2 in alkaline seawater, which is significantly lower than those of PtCo NFs (43.2 mV) and commercial Pt/C (65.2 mV), and maintain stable operation for over 500 h in 1 M KOH. X-ray photoelectron spectroscopy and density functional theory analyses reveal strong electron interaction between P atoms and PtCo, which downshifts the d-band center of Pt by 0.038 eV and optimizes the adsorption strength of active sites toward hydrogen intermediates. In situ Raman spectroscopy and CO stripping experiments further illustrate that P doping reconstructs the electronic distribution of Pt, effectively promoting water molecule dissociation. This work highlights the essential role of P in conferring both corrosion resistance and fast reaction kinetics, providing a design strategy for efficient and durable seawater electrolysis catalysts through multicomponent electronic synergism.

The electrochemical CO 2 reduction reaction (CO 2 RR) to CO faces challenges from slow kinetics and complex pathways, necessitating active, selective, and stable catalysts. This study presents a direct coordination strategy that enables the in situ growth of cobalt tetranitrophthalocyanine (CoTNPc) on Co-embedded N-rich carbon matrix (Co/NC), forming a CoTNPc/NC composite. The directly axial coordination regulates the electronic configuration of Co-N sites, accelerating the *CO formation and desorption. The CoTNPc/NC electrocatalyst achieves a peak CO Faradaic efficiency for (FE CO ) of 96.7% at −0.9 V vs. RHE in H-cell. Furthermore, in the Flow-cell, it maintains FE CO > 90% over a wide potential range (−0.4 V to −0.9 V vs. RHE) and demonstrates durability exceeding 15 h in stability testing. In situ attenuated total reflection infrared (ATR-IR) spectroscopy and Density functional theory (DFT) calculations elucidate that the remarkable performance is driven by the improved electrical conductivity and weakened interaction between the *COOH intermediate and Co sites. This work offers a novel approach to optimizing catalyst-support interactions for electrocatalyst design.
