Nickel-iron layered double hydroxide (NiFe-LDH), as a highly promising non-precious metal catalyst for the oxygen evolution reaction (OER), still suffers from several inherent drawbacks, including poor electrical conductivity, insufficient exposure of active sites, and a decline in performance under high current densities. These limitations severely restrict its practical application in the oxygen evolution reaction. Herein, a nanosheet morphology Pr-doped NiFe layered double hydroxide catalysts (Pr-NiFe-LDH) was synthesized in situ on the surface of Nickel foam modified by dielectric barrier discharge (DBD) plasma (PNF). The addition of Pr elements can effectively adjust the electronic structure of NiFe-LDH, change the position of the d-band center, and increase the number of active sites, thereby enhancing the catalytic activity. The overpotential of Pr-NiFe-LDH was reduced to 321 mV at 100 mA•cm -², significantly lower than that of NiFe-LDH (342 mV) and even superior to that of commercial RuO₂ catalyst (441 mV). The density functional theory (DFT) study indicates that adding Pr to the surface of NiFe-LDH enhances its performance in the OER. This work not only deepened the understanding of the OER mechanism in the NiFe-LDH catalyst, but also provided valuable insights for the design of efficient, low-cost and noble-metal-free electrocatalysts.

Aqueous zinc-ion batteries (AZIBs) have emerged as promising energy storage systems owing to their high safety, low cost, and environmental friendliness. However, their practical application faces critical challenges, including the formation of Zn dendrites and the occurrence of parasitic side reactions. These phenomena not only hinder ion transport kinetics but also cause rapid capacity decay and potential battery failure. To address these limitations, we developed a sustainable double-crosslinked cellulose hydrogel electrolyte by integrating micron-sized cellulose and cellulose nanofibers (CNFs). The hydrogel electrolyte, constructed from cellulose components with distinct size scales, exhibits a well-organized hierarchical porous network structure, which significantly facilitates the migration of zinc ions. Specifically, nanocellulose serves as a reinforcing filler that enhances the mechanical strength of the dual-network electrolyte, thereby inhibiting Zn dendrite growth. Additionally, abundant carboxyl polar functional groups were also introduced as high-affinity Zn 2+ binding sites to mitigate side reactions. Consequently, the assembled Zn//Zn symmetric cells with this electrolyte demonstrate superior cycling stability exceeding 1 100 h at current density of 0.5 mA/cm 2 , along with a high-capacity retention of 79.9% after 1 000 cycles in the Zn//V 2 O 5 battery. Furthermore, this cellulose hydrogel electrolyte is easily accessible and biodegradable, paving the way for the scalable production of high-performance and environmentally friendly energy storage devices.

The photocatalytic coupling of selective phenylcarbinol oxidation with hydrogen evolution has attracted considerable attention as a promising dual-functional reaction system. Herein, a lattice-matched 2D/3D NiS/CdIn 2 S 4 (NiS/CIS) Schottky heterojunction is rationally designed for efficient dual-functional photocatalysis under visible light. Structural analyses confirm the uniform deposition of NiS nanosheets on octahedral CIS with a lattice mismatch below 5%, ensuring coherent interfacial contact. The optimal 3% NiS/CIS composite exhibits exceptional hydrogen and benzaldehyde production rates of 2636.4 and 2717.6 μmol g −1 h −1 , respectively—representing enhancements of 39.7 and 38.0 times over pristine CIS. The catalyst also demonstrates remarkable stability, retaining over >99.0% activity after six cycles. Mechanistic studies reveal that the Schottky junction facilitates spatial separation of photogenerated carriers: electrons migrate to NiS, prolonging charge carrier lifetimes and lowering the hydrogen evolution overpotential, while holes accumulate on CIS that facilitated phenylcarbinol adsorption to drive selective phenylcarbinol oxidation via a carbon-radical pathway. This work provides a viable approach for designing efficient bifunctional photocatalysts through lattice-matched interface engineering.

Modulating the electronic interaction between catalysts and supports is recognized as an effective strategy to enhance catalytic performance. However, due to the complex electronic or coordination environments at the catalyst-support interface, designing supports capable of anchoring complex-structured metal nanoparticles (NPs) remains a challenge. Herein, we designed porous SnO 2 nanotubes (NTs) using an electrospinning and chemical etching strategy and successfully anchored nanoflower-like AuPdCu NPs composed of self-assembled nanowires onto their surface. The porous structure of SnO 2 NTs provides abundant anchoring sites for AuPdCu NPs. Furthermore, the petal-like structure of the AuPdCu NPs is firmly bonded to the pores of the SnO 2 NTs through a gear-like interlocking mechanism, resulting in a strong bond between the catalyst and support. The unique structural advantages of AuPdCu/SnO 2 , along with the electronic interaction between the support and catalyst, synergistically enhance catalytic performance. AuPdCu/SnO 2 exhibits a high mass activity of 4.53 A·mg Pd −1 for the ethanol oxidation reaction (EOR) and maintains a high current density (3.39 mA cm −2 ) after a 10000 s stability test. Density functional theory (DFT) calculations confirm that the electronic interaction between AuPdCu NPs and SnO 2 NTs modulates the d-band center, thereby optimizing the adsorption strength of reaction intermediates and promoting the complete oxidation of ethanol.

Transition metal dichalcogenides (TMDs) have attracted significant attention in electronic devices, energy storage, and catalysis owing to their distinctive electronic properties and abundant active sites. Introducing mesoporosity into TMDs is extremely favorable to enhance the host-guest interactions and improve their performance, but very challenging. Herein, we report a universal electrostatic assembly strategy for the synthesis of mesoporous carbon/heteroatom-doped TMDs microspheres with radially oriented pores, using polydopamine (PDA) and polyoxometalates (POMs) clusters as interactive precursors. By employing POMs (e.g., H 3 PW 12 O 40 ) as metal sources and mesoporous PDA microspheres as templates, we successfully synthesized a series of mesoporous C/heteroatom-doped TMDs microspheres (TMDs = P-WS 2 , Si-WS 2 , P-MoS 2 , Si-MoS 2 ). The resulting hybrid microspheres feature an open porous architecture, high charge-carrier mobility, and abundant active sites, benefiting from their high crystallinity and in situ heteroatom doping. When employed in chemiresistive gas sensors, these C/TMDs microspheres demonstrate exceptional room-temperature NO 2 sensing performance, including high sensitivity, excellent selectivity, and rapid response. Density functional theory (DFT) calculations reveal that heteroatom doping (e.g., P) can enhance the structural stability of adsorbed NO 2 , strengthen orbital hybridization with TMDs, and facilitate efficient charge transfer, thereby dramatically improving sensing performances.

The urea oxidation reaction (UOR) has garnered significant attention as a promising alternative to the oxygen evolution reaction (OER) for water electrolysis, owing to its superior kinetic properties that enable enhanced hydrogen production efficiency. However, the practical deployment of UOR technology remains hindered by the persistent challenge of developing electrocatalysts that simultaneously achieve high activity, long-term operational stability, and cost-effectiveness. Herein, we report a facile, eco-friendly, one-step synthesis process to fabricate nickel–tin electrocatalyst (Ni–Sn) on Ni foam for catalyzing UOR via electrodeposition, using SnCl 2 ·2H 2 O and NiSO 4 ·6H 2 O as the Sn and Ni sources, respectively. Notably, the Ni–Sn electrocatalyst with a Ni/Sn ratio (90.39:8.61 at%) exhibits remarkable UOR activity, delivering a low potential of 1.493 V versus RHE to reach 10 mA·cm −2 , a small Tafel slope of 83.5 mV·dec −1 , and excellent stability with minimal decay after 100 h of continuous operation in alkaline urea electrolyte (1.0 M KOH + 0.33 M urea). The excellent activity of the Ni–Sn electrocatalyst for UOR benefits from the synergistic interaction between Ni and Sn, which modulates the electronic structure and accelerates charge transfer kinetics, thereby significantly enhancing reaction dynamics. Furthermore, the intrinsic superhydrophilicity of the Ni–Sn catalyst promotes efficient mass transport of reactants and products, contributing to its superior bifunctional catalytic performance for UOR.

Developing high-performance TENG based on electrospun nanomaterials is one key to maximize the value as a sustainable green energy technology. Here, a performance-enhanced TENG is constructed by using electrospun TPU/Tb(BA) 3 phen/PVP nanofiber membrane and PVDF/PVP nanofiber membrane as two friction layers. A “dual-enhancement strategy” is proposed and implemented: a lot of micro contact points are created by utilizing the nanofiber membrane network structure to greatly increase the effective contact area and significantly enhance the frictional electrification effect. Meanwhile, a multitude of triboelectric charge capture sites are obtained via Tb(BA) 3 phen-TPU/PVP two-phase interface that is established by doping functional filler of Tb(BA) 3 phen to reduce charge dissipation and increase the accumulation of frictional charges. As the content of Tb(BA) 3 phen increases from 0 to 15% in TPU/Tb(BA) 3 phen/PVP nanofiber membrane, the output performance of TENG gradually increases from 3.3 μA, 50 V to 10.1 μA, 200 V. Moreover, electrospun nanofiber membranes are endowed with rich properties, including good flexibility, stretchability, hydrophobicity, and fluorescence. The assembled TENG with high performance and excellent multifunctional integration has great potential in wearable electronic devices and energy harvesting. Graphical abstract

Urea-assisted overall water splitting has emerged as a cost-efficient and promising technology for hydrogen production, which not only avoids the formation of an explosive H 2 /O 2 gas mixture but also significantly reduces the energy input required for water electrolysis. In this work, a bifunctional CuNNi 3-x Mn x catalyst self-supported on nickel foam (NF) was synthesized via a facile hydrothermal method followed by annealing, resulting in highly efficient and stable electrocatalysts for both the urea oxidation reaction (UOR) and the hydrogen evolution reaction (HER). Controlled Mn doping allows precise modulation of the electronic structure of CuNNi 2.4 Mn 0.6 at the Ni active sites, simultaneously enhancing the adsorption/desorption kinetics of hydrogen intermediates (H∗) and facilitating C–N bond cleavage in urea. The optimized CuNNi 2.4 Mn 0.6 catalyst requires only 1.336 V for UOR and 44 mV for HER to achieve a current density of 10 mA cm −2 , demonstrating remarkable bifunctional activity. Moreover, when employed as both anode and cathode in a urea-assisted overall water splitting system, the catalyst enables a cell voltage of merely 1.526 V at 10 mA cm −2 , significantly lower than that required for conventional water electrolysis (1.695 V vs. RHE). The system also exhibits excellent durability, maintaining stable performance for over 30 h at 10 mA cm −2 without significant activity loss. This work provides a foundation for the further exploration of transition metal-based bifunctional electrocatalysts, paving the way for energy-efficient hydrogen production and simultaneous treatment of urea-rich wastewater.

Carotenoids, a class of naturally occurring pigments ubiquitously distributed across plant and animal kingdoms, serve vital biological functions in photoprotection and antioxidant defense mechanisms. Within plant systems, these compounds critically modulate photosynthetic efficiency under drought stress conditions. While carotenoid content fluctuations offer a reliable biomarker for evaluating plant drought responses, conventional chemical quantification methods remain labor-intensive and unsuitable for large-scale agricultural monitoring. This investigation employs hyperspectral imaging technology (operating in the 859–1705 nm spectral range) to acquire spectral signatures from Chrysanthemum × morifolium (Ramat.) Hemsl. samples, subsequently applying five spectral preprocessing techniques to optimize data quality. Three feature selection algorithms (Successive Projections Algorithm, Max-Relevance Min-Redundancy, and Competitive Adaptive Reweighted Sampling) were employed to identify diagnostically significant wavelengths, while three regression models (Random Forest Regression, Partial Least Squares Regression, and Gradient Boosting Machine) were constructed for carotenoid prediction. SHapley Additive exPlanations analysis was performed to assess the interpretability and relative contributions of different feature selection approaches. Experimental results demonstrate that the SPA-Random Forest Regression hybrid model achieved optimal prediction performance (R C = 0.9545, RMSE C = 0.0096, R P = 0.9228, RSME P = 0.0134). Notably, the Random Forest Regression algorithm attained 99.03% classification accuracy in drought stress discrimination. This methodology establishes the viability of integrating hyperspectral imaging with machine learning as a non-destructive analytical framework for simultaneous carotenoid quantification and plant drought stress assessment.

To address the failure of traditional filtration reducers under high-temperature and high-salinity conditions in ultra-deep drilling, this study developed a novel organic–inorganic hybrid nanocomposite filtrate reducer (Nano-DAND). Nano-DAND was synthesized via free-radical copolymerization of N,N-diethylacrylamide (DEAM), 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acryloyloxyethyltrimethyl ammonium chloride (DAC), and N-vinylcaprolactam (NVCl), reinforced with vinyl-functionalized silica nanoparticles (SVS) prepared by SDS-assisted dispersion and vinyltriethoxysilane (VTES) surface modification. Structural characterization (FTIR, ¹H NMR, TGA, TEM, and PSD) confirmed the successful incorporation of SVS into the polymer matrix, with Nano-DAND exhibiting high thermal stability (decomposition temperature > 331 °C). Under 240 °C and 20 wt% NaCl, Nano-DAND achieved FL API of 7.8 mL and FL HTHP fluid loss of 31.2 mL, significantly outperforming commercial additives such as Driscal-D and Polydrill, exhibiting FL HTHP at 81.8 mL and 114.8 mL, respectively. SEM analysis of filter cakes showed that Nano-DAND formed a dense and uniform mud cake, effectively reducing porosity and permeability. Rheological tests indicated that Nano-DAND maintained good viscosity retention (>50 %) after thermal aging, Adsorption and zeta potential analyses revealed that Nano-DAND interacts with bentonite platelets through hydrogen bonding, electrostatic attraction, and ionic bridging, forming a stable three-dimensional network that enhances filter cake integrity and suppresses fluid loss. These findings highlight Nano-DAND’s potential as a robust filtration control agent for ultra-deep drilling applications.

Colloidal InAs quantum dots (CQDs) are promising materials for shortwave infrared (SWIR) optoelectronics because of their heavy-metal-free composition and tunable long-wavelength emission. However, achieving high-quality InAs CQDs with narrow linewidths and symmetric emission beyond 1500 nm remains challenging, primarily due to uncontrolled growth kinetics and surface defects during high-temperature synthesis. Here, we report a unified strategy that overcomes this synthesis–emission trade-off by integrating in situ HBr-assisted dual-site etching with a diffusion-dynamics-controlled continuous injection process. This approach stabilizes the nanoclusters and seeds simultaneously, suppresses secondary nucleation, and enables kinetically synchronized growth. Complementary density functional theory (DFT) calculations offer a mechanistic insight into the surface-driven growth modulation and confirm that Br – treatment enhances facet-specific binding and suppresses mid-gap states. The resulting InAs CQDs exhibit symmetric single-peak emission centered at ∼1510 nm with an average diameter of ∼7.2 nm, narrow size distribution (coefficient of variation ( C V ) = 11.5%), excitonic linewidths (half-width at half maximum (HWHM) < 70 meV), and long-term colloidal stability. These results redefine the synthetic framework for III–V CQDs and provide a scalable route for high-performance heavy-metal-free SWIR emitters.

Triethylamine (TEA), a hazardous industrial volatile organic compound, requires sensors with rapid response and ppb-level sensitivity. This study synthesized m-LaVO 4 nanospheres with controlled exposed crystal facets via a hydrothermal method. The optimized material, featuring a layered morphology and dominant (200) plane, showed a high response of 27.2 to 100 ppm TEA at 225°C with a 5 s response time, shortening to 2 s at 15 ppm. The sensor demonstrated a low detection limit of 1 ppb, excellent selectivity, repeatability, long-term stability, and light-modulated sensing behavior. These properties are attributed to the unique layered structure and surface characteristics of m-LaVO 4 , making it a promising candidate for efficient, low-concentration TEA detection.
