The main objective of this study is to investigate the impact and mechanism of soy lecithin incorporation into the gelatin-cinnamaldehyde emulsion, focusing on how it influences emulsion stability during the electrospinning process. In this work, a cinnamaldehyde/gelatin/soy lecithin (CGS) fiber membrane with excellent antibacterial properties was successfully created. The addition of soy lecithin improves the stability of the emulsion and improves the loading performance and fiber morphology of the CGS fiber membrane. Fourier Transform infrared spectroscopy (FTIR) and urea addition confirmed that soy lecithin may strengthen the interface structure of gelatin in the oil and water phases through hydrogen bonds, thus enhancing the stability of the emulsion in electrospinning. The application tests also revealed that the CGS fiber membrane effectively preserved the sensory quality of beef. This study indicates that the vector construction method can extend the utilization of cinnamaldehyde in food industry.

The low sustainable current density in darkness restricts the advancement of photocathodic protection (PCP) for steels in marine environments. A combination of MoO 3 /WO 3 (Mo/WO 3 ) was proposed as an electron storage system to enhance capacitance and charge/discharge rates. Subsequently, incorporating ZnIn 2 S 4 (ZIS) extended light harvesting and improved photocarrier separation efficiency, resulting in efficient round-the-clock PCP performance. Under illumination, the open circuit potential (OCP) of 10Mo/WO 3 @ZIS coupled with 304SS reaches −0.97 V vs. Ag/AgCl, approximately 600 mV and 140 mV more negative than corrosion potential (E corr ) of 304SS and WO 3 @ZIS coupled 304SS, whth photocurrent density of 134 μA/cm 2 . The excellent PCP performance is attributed to superior photocarrier separation and enhanced light-harvesting capability. Notably, in the dark, the OCP of the coupled system remains ca . 0.4 V below the E corr of 304SS, with an average current density of 30 μA/cm 2 , demonstrating the regulated electron storage capabilities of Mo/WO 3 . Furthermore, capacity and charge/discharge rates correlate with Mo/W ratio and electrolyte species. 10Mo/WO 3 @ZIS exhibits a charge capacity of 2.93 mC, nearly 3 times higher than that of WO 3 @ZIS. The innovative application of MoO 3 and WO 3 proves the potential to regulate the electron storage performance, revealing the factors for photoelectron storage/release.

Vanadium dioxide (VO 2 ) is a remarkable thermochromic material for application in adaptive infrared camouflage due to the reversible phase transition that is coupled with an abrupt change in infrared optical properties . However, the relatively high phase transition temperature and the unclear infrared optical modulation characteristics in the mid-infrared and far-infrared regions largely restrict its practical applications. Here, W-doped VO 2 nanoparticles were successfully prepared to reduce the transition temperature. When the effective doping amount of W was 1.70%, the transition temperature decreased to 43.2 °C. Importantly, the infrared properties of W-doped VO 2 nanoparticles were studied in both MWIR (3–5 μm) and LWIR (8–14 μm) thermal atmospheric windows, for the first time, which exhibited significant infrared optical changes, with emissivity variation of Δε = 0.17 and Δε = 0.28, respectively. These favorable results further promote the development of the adaptive camouflage.

The increasing demand for sustainable biofuels has driven the development of efficient catalysts for hydrodeoxygenation (HDO) and isomerization of bio-oils. This study investigates the performance of a W-modified unsupported MoNiP catalyst for the hydroisomerization of palm oil to produce low-freezing-point biofuels. The MoNiP-W catalyst was synthesized via a one-pot method and characterized using XRD, BET, XPS, H 2 -TPR, NH 3 -TPD, Py-IR, and TEM-Mapping. Under optimized reaction conditions (360 °C, 3 MPa H 2 pressure, 3 h −1 LHSV, and 300:1 H 2 /oil ratio), the catalyst achieved 100 % palm oil conversion and a C 5 -C 20 isoparaffin selectivity of 70.6 %. A 240-hour stability test revealed that the catalyst maintained a stable isomerization rate of approximately 60 % without significant deactivation. These results demonstrate the potential of W-modified unsupported MoNiP catalysts for the cost-effective and sustainable production of low-freezing-point biofuels. The enhanced activity is attributed to the synergistic effect between Mo, Ni, P, and W, which optimizes the catalyst’s acidity and promotes hydroisomerization reactions.

Due to the unique characteristics like large specific surface area of Transition Metal Dichalcogenides (TMDs) and its well-defined hollow Metal-Organic Framework (MOF), it is widely used in dye-sensitized solar cells (DSSCs), oxygen reduction (ORR) and oxygen evolution reaction(OER). Herein, we prepare N-doped C hollow metal organic frame structure materials , which are used as a template, WS 2 nanocrystals are grown and encapsulated in MOF with interfacial W–N coupling centers. During the pyrolysis, after carbonizing, ZIF-67 becomes Co, N-doped C materials, and the growth of WS 2 is effectively suppressed, creating multi-functional groups W–N/C@Co 9 S 8 @WS 2 materials. The synthesized material is employed as a counter electrode (CE) for dye-sensitized solar cells, its high power conversion efficiency (PCE) (7.38%) based DSSC under AM 1.5G irradiation was much more than that of Pt (7.06%). Such excellent electrocatalytic performance was resulted from the unique frame pore structure , the synergistic effect of WS 2 , Co 9 S 8 and W–N multi-functional groups. Besides, W–N/C-4@Co 9 S 8 @WS 2 shows E 1/2 ≈0.84 V and a little Tafel slope of 44 mVdec −1 when employed as electrocatalysts for ORR and potential ≈ 1.79 V to achieve the current density of 10 mA cm −2 , which are lower than that of Pt/C ≈ 1.91 V catalysts in 0.1 M KOH.

A series of (Y, Yb, Zr, Hf, Sn, W)O 2−δ high-entropy ceramics with varying mole fraction of main elements were synthesized for the first time through the solid-state reaction synthesis method. The microstructure, phase composition, and properties of the prepared materials were thoroughly analyzed and tested. The results indicate that the phase composition transformed from a single-phase fluorite structure to a single-phase C-type rare earth sesquioxide structure as the mole fraction of +3 cations increases. The thermal conductivity of the prepared high-entropy ceramics with porosity of 49.8%–50.1% is very low ranging from 0.33 to 0.37 W·m −1 ·K −1 . Among them, the single-phase C-type rare earth sesquioxide with a higher oxygen vacancy concentration was employed as a catalyst in the CO 2 hydrogenation reaction, attaining a high CO 2 conversion rate of 82.0%. The obtained results have deepened understanding of the role of oxygen vacancies and have important guiding significance for the study of high-entropy oxides with fluorite derived structures.

N-heterocycles with quinoline structures hold significant importance within the chemical and pharmaceutical industries. However, achieving their efficient transformations remains a vital yet challenging endeavor. Herein, a series of W-doped Ga2O3-NC catalysts were synthesized using a Ga-MOF-derived strategy through a simple solvothermal method, with a remarkably high activity and selectivity towards the oxidative dehydrogenation ofN-heterocycles. Furthermore, the MOF-derived W-doped Ga2O3-NC catalysts exhibit remarkable substrate tolerance and recyclability. The outstanding catalytic activity was attributed to the robust synergistic interaction between the W species and the Ga2O3-NC carrier, which facilitates the activation of hydrogen atoms in the C-H and C=N bonds on both the oxygen molecule and the substrate to produce H2O2. Additionally, the solvent effect of methanol can significantly enhance dehydrogenation due to its strong ability to donate and accept protons of hydrogen bonding. The present work provides a new approach to MOF-derived non-precious metal catalysts for achieving the efficient oxidation dehydrogenation ofN-heterocycles.

A series of newly synthesized red-emitting phosphors, La 3 Ga 5 SnO 14 :Eu 3+ , were produced through high-temperature solid-state synthesis methods. The phase purity, particle morphology and optical properties were systematically investigated in this work. The prepared fluorescent material has high phase purity. La 3 Ga 5 SnO 14 :Eu 3+ has a strong red emission peak at 612 nm at the excitation at 268 nm, which is caused by the radiative transitions of electrons ( 5 D 0 → 7 F 2 ). The optimal doping concentration of Eu 3+ was observed to be 30 mol% in this series of La 3 Ga 5 SnO 14 :Eu 3+ . The mechanism of concentration quenching was determined to be dipole-quadrupole interaction. The chromaticity coordinates of La 3 Ga 5 SnO 14 :30 mol%Eu 3+ were (0.648, 0.352) with a corresponding high color purity of 100%. The thermal stability of the phosphor was also characterized. The luminous intensity could be sustained at 54% at 480 K. The quantum efficiency of the La 3 Ga 5 SnO 14 :30 mol%Eu 3+ phosphor is 64.4%. The exhaustive findings from this study form the basis for advocating the application of these phosphors in light-emitting devices.

The demand for white-light luminescent materials for the white-light-emitting diodes (W-LEDs) field has been growing in modern life. In this work, a series of Sn 2+ and Mn 2+ ions co-doped highly transparent white-light emitting oxyfluoride glasses (precursor glass, PG) and Sr 2 LuF 7 glass-ceramics (GC) were successfully prepared by the melt-quenching technique. Their luminescent and structural properties were investigated by the transmission spectra, excitation and emission spectra at different temperatures (300-500 K), luminescent decay curves, XRD, and TEM characterizations. Upon excitation with ultraviolet (UV) light, tunable broadband blue-white light emissions of Sn 2+ were obtained by adjusting the concentration of Sn 2+ ions. A conspicuous energy transfer process from Sn 2+ to Mn 2+ was observed in Sn 2+ /Mn 2+ co-doped samples. Tunable broadband luminescence between blue-white light and orange-red light regions and nearly pink-white light emission was realized by varying Mn 2+ concentration. Furthermore, compared to PG samples, the emissions were enhanced in GC samples due to the crystallization of Sr 2 LuF 7 nanocrystals. Excellent thermal stability was also performed in these Sn 2+ doped PG and GC samples with a recovering value of 96 % and 98.8 %, respectively. Simultaneously, Sn 2+ doped PG and GC samples also own good optical thermal sensitivities with an S A value of 2.28 % and 2.47 % K - 1 , respectively. Our results indicate that these Sn 2+ /Mn 2+ co-doped PG and GC may serve as tunable light sources under UV excitation and have prospects on the ratiometric optical thermometry fields.

The hydroisomerization of isobutane is of considerable practical significance for the development of low-carbon and high-efficiency ethylene production technologies. However, conventional noble metal-solid superacid catalysts used for this reaction suffer from drawbacks including high cost and catalyst deactivation caused by the loss of halogen species and other active components. Herein, a series of highly dispersed W-Cu/Beta catalysts were designed and prepared via a facile ion-exchange method, and their catalytic performances toward isobutane hydroisomerization were systematically investigated. The results show that the introduction of WO x species effectively suppresses strong Brønsted acid sites of the Beta zeolite and modifies the Brønsted/Lewis acid balance of W-Cu/Beta catalysts. Although both Brønsted and Lewis acid site concentrations decrease with increasing W loading, Brønsted acidity is reduced to a greater extent, resulting in a lower Brønsted/Lewis acid site ratio. This acidity regulation is associated with suppression of undesired cracking reactions and improved selectivity toward n-butane. Under reaction conditions of 2 MPa, 380°C, and a weight hourly space velocity of 2.0 h ‒1 , the 5%W-Cu/Beta catalyst exhibits the best catalytic performance with isobutane conversion of 62.3% and n-butane yield of 32.4%. This enhanced catalytic behavior is attributed to optimized acidity and an appropriate distribution of catalytic active sites. Kinetic analyses indicate that WO x introduction alters the apparent kinetic behavior of the catalysts and is accompanied by an increase in apparent activation energy. The improved catalytic selectivity is correlated with changes in acidity distribution and suppression of cracking pathways rather than direct evidence of carbocation stabilization.

To address the issues of insufficient strength and brittleness in traditional W-La 2 O 3 alloys for diamond wire busbars, this work highlights a composite strengthening strategy by inducing La 2 O 3 and LaB 6 at the same time. A systematic comparison was conducted on the composition and microstructure evolution as well as the corresponding compressive properties. The results show that the additional LaB 6 triggers the grain refinement of W with the grain size reduced from 29.96 μm to 22.35 μm via the in-situ formation of fine La 2 O 3 particles. Moreover, LaB 6 also promotes the generation of γ-fiber texture associated with dynamic recrystallization during thermal processing. The as-obtained alloy (W-La 2 O 3 -LaB 6 ) exhibits a compressive strength of 2562.2 MPa in the as-rotary forged state, 408.5 MPa higher than that of the traditional alloy(W-La 2 O 3 ). Concurrently, the corresponding fracture mode transforms from intergranular brittle fracture to transgranular ductile fracture. By virtue of the synergistic effect of multiple strengthening and regulating mechanisms including second-phase strengthening, grain refinement strengthening and texture regulation, LaB 6 efficiently improves the compressive properties and processability of W-La 2 O 3 alloys. This work provides a technical support for the development of high-performance photovoltaic tungsten wire busbars with a low wire breakage rate.

W/Mo-modified Ni 3 S 2 features local crystalline/disordered interfacial domains. • The electrode requires 101 mV at 10 mA cm −2 with a 69.9 mV dec −1 Tafel slope. • Stable HER operation is maintained for 100 h at 100 mA cm −2 . • DFT suggests modulated H* adsorption energetics and a lower water dissociation barrier. The rational engineering of crystalline/disordered interfacial domains with tailored electronic properties represents a promising strategy for developing high-performance electrocatalysts for the hydrogen evolution reaction (HER). Herein, a three-dimensional self-supported W/Mo-modified Ni 3 S 2 -based electrocatalyst with local crystalline/disordered interfacial domains (Ni 3 S 2 @W:Mo-0.2:0.2) is fabricated through a facile hydrothermal strategy. Structural characterizations support the coexistence of crystalline Ni 3 S 2 domains and adjacent Ni-containing W/Mo/O-associated disordered regions, while the combined experimental and theoretical results suggest interfacial electronic regulation and enhanced alkaline HER kinetics. The local interfacial structure is associated with interfacial charge-transfer behavior. Consequently, the electrode requires an average overpotential of 101.00 ± 1.73 mV at 10 mA cm −2 in 1 M KOH, together with improved apparent kinetics, reduced charge-transfer resistance, and stable operation at 100 mA cm −2 for 100 h. The enhanced activity arises from the combined contributions of accessible surface area, ECSA-normalized apparent specific activity, and charge-transfer kinetics. Density functional theory (DFT) calculations suggest modulated H* adsorption energetics and a lower water dissociation barrier. Gas chromatography (GC) analysis quantitatively confirms sustained H 2 generation. This work provides insights into interfacial engineering and electronic structure regulation for advanced electrocatalyst design.
