Solar energy, as a renewable and clean energy source, is utilized to obtain freshwater and power generation, serving as a sustainable solution to address water scarcity and power shortages. This study proposes a strategy for power generation based on salinity gradients and designs an inclined composite evaporator. The evaporator features a nickel foam substrate functionalized through cross-linking of sodium alginate (SA) and tannic acid (TA) with trivalent iron ions (Fe 3+ ), enabling efficient electricity generation and freshwater production, named as SA/TA-Fe@Ni. (“Fe” indicates trivalent iron ions (Fe 3+ ) crosslinking) The TA-Fe 3+ coordination complex formed in situ on the evaporator surface appears black and exhibits excellent broad-spectrum light absorption capability. The evaporator is designed with an inclined configuration, which can significantly enhance the water transport performance. The enhanced evaporation flux establishes a stable salinity gradient at the interface, which constitutes the core driving mechanism for salinity gradient power generation. The inclined SA/TA-Fe@Ni evaporator achieves an evaporation rate of 2.14 kg•m −2 •h −1 under standard sun irradiation (one sun). It simultaneously demonstrates excellent seawater desalination and wastewater purification, while generating an open-circuit voltage of 83.7 mV. The system demonstrates outstanding salt tolerance, stability, durability, and environmental adaptability, fully demonstrating the potential of practical applications.

In the study, we present a molten salt-assisted hard-templating strategy for synthesising cobalt and nitrogen-doped carbon nanoflowers (Co/N-CNFs) as high-performance electrocatalysts for highly sensitive and selective electrochemical dopamine detection. The hierarchical surface roughness and excellent conductivity of Co/N-CNFs, combined with their uniformly dispersed Co sites, facilitate exceptional electrocatalytic performance toward dopamine oxidation. Electrochemical measurements demonstrated that the Co/N-CNFs composite exhibited outstanding performance for dopamine sensing, featuring a broad linear response range from 1 to 1000 µM and an exceptionally low detection limit of 0.13 µM. Moreover, the sensor exhibited remarkable stability, excellent anti-interference capability, and high accuracy in actual sample analysis. The work presents an innovative design strategy for Co/N-doped carbon catalytic systems, enabling the detection of dopamine in spiked human serum samples.

Experimental and numerical investigations are conducted to characterize the polyvinylpyrrolidone (PVP) fluid cone in the solution blow spinning (SBS) process. The fluid cone evolution is captured by an industrial microscope camera. A novel force analysis based on air drag force, outside pressure, inside pressure, and surface tension is performed. Numerical methods are applied to analyze the flow field near the concave cone and spindle. The results show that the ethanol improves the spinnability of PVP solutions by simultaneously increasing viscosity and reducing surface tension. A droplet-to-fluid cone evolution model is observed for the first time in the SBS process, and a thin fluid cone represents the ideal spray pattern for fiber production. The increase in viscosity causes fluid cones to appear under lower air pressure conditions. The fluid cone contracts with increasing air pressure but expands with increased feed ration or solution viscosity. Reducing the average fiber diameter can be achieved by suppressing the fluid cone size. The instability of the fluid cone is mainly attributed to insufficient air drag force, premature solidification, and fiber whipping. The low-speed reverse airflow makes the concave cone favorable for preventing premature solidification. In the SBS process, the formation of the fluid cone results from the interaction of three control parameters: outside pressure, inside pressure, and surface tension.

Iron-based metal organic frameworks (Fe-MOFs) have been regarded as the ideal precursors for synthesis of iron-carbon micro-electrolysis (IC-ME) materials. However, their conventional autoclave-based fabrication limits large-scale application, and the potential of the resulting Fe@C composites derived from Fe-MOFs for Cr(VI) reduction remains underexplored. Herein, a facile stirring method conducted under ambient conditions was successfully developed. The evolution from Fe-MOFs to Fe@C was comprehensively characterized, and its reductive capacity for Cr(VI) was systematically evaluated. The effect of key experimental parameters including reaction time, initial pH value, electrolyte concentration, catalyst dosage, and environmental matrices on Cr(Ⅵ) removal were investigated in detail on the basis of the concentration variation of Fe ions released into water. The obtained results indicated that the rate of Cr(VI) removal-efficiency change (Δη/Δt) was positively corelated with that of Fe(II) concentration change (Δ C Fe(II) /Δ t) and 98.2% of Cr(VI) was removed within 60 min under the optimized conditions. According to the results of XPS with ion sputtering, Cr(VI) was removed via multiple pathways including adsorption, reduction and co-precipitation. This work not only offers a scalable route for MOFs-derived IC-ME materials, but also provides mechanistic insights into Cr(VI) removal from the perspective of Fe(II) dynamics.

Actinide (An)-based materials have shown fascinating electronic and bonding properties related to f orbitals, demonstrating significant potential in catalysis. However, the catalytic utility of uranium is constrained by its low electron affinity and high reduction potential. In this study, we designed an asymmetric f-p-d gradient orbital coupling strategy through spatial engineering of the hybridization among U 5f, O 2p, and Ti 3d orbitals on TiO 2 nanorod arrays (U/TiO 2 NRA). This asymmetric 5f-2p-3d structure modulates the band structure to improve light absorption capacity and prolong the lifetime of charge carriers, while optimizing the adsorption energetics of reaction intermediates, thus enabling efficient stepwise water dissociation. The fabricated photoanode achieves a noteworthy photocurrent density and excellent operational stability, outperforming most reported TiO 2 -based catalysts. Through theoretical analyses, it is verified that the 5f buffer band at the asymmetric U−O−Ti sites, mediated by 5f-2p-3d gradient orbital coupling, facilitates electron transfer, which effectively promotes the adsorption, activation, and stepwise dissociation of water molecules at the dual atomic sites. In this work, a new design paradigm is established for the development of high-performance An-based catalytic materials.

A Cu: MoO 3 /g-C 3 N 4 binary heterojunction photocatalyst was synthesized via a hydrothermal method, achieving a light response that covers nearly the entire visible region. The material shows a strong, broad absorption band from 400 to 700 nm, significantly improving its visible-light harvesting and utilization efficiency. Optimization of the g-C 3 N 4 , Cu, and Mo molar ratios further enhanced the catalyst’s redox performance under visible-light irradiation. Through combined XPS, UV–vis, and in situ DRIFTS characterizations, it was verified that the Cu: MoO 3 /g-C 3 N 4 photocatalyst possesses a wide visible-light absorption range and effectively transforms absorbed long-wavelength photons into photogenerated electron-hole pairs, thereby facilitating the separation and transfer of charge carriers. Due to the simultaneous enhancement of broad-spectrum light capture and charge separation/transfer efficiency, this catalyst demonstrates excellent catalytic activity in visible light-driven CO 2 conversion, with a maximum methanol production rate of 102.52 μmol·g −1 ·h −1 . This work verifies the feasibility of efficient visible light-driven CO 2 conversion and provides a viable design approach and reference for constructing multi-metal-based photocatalysts with full visible light response.

A lightweight, multifunctional polyamide acid (PAA)/carbonyl iron powder (CIP) composite aerogel with integrated thermal insulation and microwave absorption capabilities is developed via multi-structure design. With polydopamine (PDA) modified melamine foam (MF), this study achieves uniform dispersion of CIP and robust interfacial bonding. The results demonstrate that the PDA modification time and PAA content have a significant effect on the properties of composite aerogels. The composite aerogel achieves lowest thermal conductivity with 6 h modification time and 8% PAA due to the optimized structure. Moreover, the peak microwave absorption performance is attained with 18 h modification and 6% PAA, resulting from optimal interfacial polarization loss and impedance matching. This study achieves a balance between thermal insulation and microwave absorption performance through microstructure design, providing a solid foundation for advanced multifunctional materials.

Cannabidiol (CBD), a non-psychoactive terpenophenolic compound derived from Cannabis sativa , exhibits broad-spectrum pharmacological activities but is highly susceptible to oxidative, photolytic, and thermal degradation, making it challenging to preserve and use in therapeutics. Therefore, this study compares the preservation efficiency of a powder-based hydroxypropyl-β-cyclodextrin (HP-β-CD) inclusion-complex system for cannabinoid stability and solubility and medium-chain triglyceride (MCT) oil, a common lipid-based carrier in commercial formulations. Formulation characterizations, including CBD content (HPLC), color change, solvent residues, moisture, particle size, and zeta potential, were measured. DPPH experiments revealed that the HP-β-CD complex exhibited higher antioxidant activity (89.2%, EC₅₀ = 45.3 µg/mL) than the MCT oil system (83.6%, EC₅₀ = 58.7 µg/mL), with ascorbic acid serving as the control (EC₅₀ = 12.4 µg/mL). Additionally, photostability testing (8000 lux) demonstrated superior CBD retention in the HP-β-CD complex (>90%) compared with MCT oil (∼20%), indicating substantial light-induced degradation in the oil system. HP-β-CD complex retained 92–93% CBD (k = 0.0084 week⁻¹; t₁/₂ = 82.5 weeks) versus 88% in MCT oil. At 40 °C, HP-β-CD complex preserved 86–87% CBD. GC-FID/GC-MS showed that HP-β-CD powder preserved CBD with only trace degradation (<0.1–1.0%). In contrast, MCT oil produced higher cannabinoid by-products (0.1–6.21%), and greater antioxidant degradation (2.5–8.6% vs 0.5–2.1%). The results suggested that CBD degradation follows matrix-dependent kinetics, with cyclodextrin encapsulation significantly reducing the apparent degradation rate constants relative to oil-based solubilization under identical stress conditions.

Polyurea coating offers robust protection against weathering and corrosion, yet the limited wear resistance remains a bottleneck for long-term service in marine environments. In this study, a high-performance polyurea coating incorporating APTES-modified Al 2 O 3 nanoparticles was developed on Q235 steel. The surface-grafted amino groups not only improve the compatibility between Al 2 O 3 nanoparticles and polymer matrix but also facilitate the establishment of strong interfacial bonds within the polyurea network, thereby significantly bolstering the coating's mechanical properties and environmental durability. Compared to pure polyurea, the composite coating achieves a 41.1% lower mass loss under a 1000 g load and 2000 wear cycles, demonstrating reliable wear resistance. Moreover, the nanoparticles enhance the structural compactness of the coating and increase the tortuosity of the diffusion pathways for corrosive mediums, leading to a remarkable enhancement in corrosion protection. After immersion in 3.5 wt% NaCl solution for 120 days, the low-frequency impedance modulus (| Z | f =0.01Hz ) of the composite polyurea coating remains above 10 11 Ω·cm 2 . Meanwhile, the composite polyurea coating exhibits superior resistance to UV aging. These findings demonstrate the great potential of this nano-alumina-reinforced polyurea composite for application in high-performance protective coatings.

Syngas fermentation using CO-rich industrial off-gases offers a sustainable route for large-scale bioethanol production. However, the resulting fermentation broths typically contain both high concentrations of suspended microbial cells and soluble proteins, posing major challenges for efficient downstream processing. In this study, commercially available ceramic membranes with nominal pore sizes spanning the microfiltration to nanofiltration range (100, 15, 5, and 2 nm) were systematically evaluated for the one-step simultaneous removal of cells and proteins from both simulated and real bioethanol fermentation broths. All membranes exhibited defect-free surfaces and narrow pore size distributions. Results show that microbial cells were completely retained by all membranes, while soluble proteins were effectively removed with increasing rejection as pore size decreased. Among them, the 15 nm ceramic membrane (CM-15) exhibited the best overall performance, delivering a favorable balance between permeation flux and protein rejection (>98%). Fouling analysis revealed that flux decline was dominated by protein gel layer formation rather than pore blocking, and membrane fouling was largely reversible, with full flux recovery achieved through sequential alkaline and acid cleaning. Importantly, pilot- and engineering-scale operation confirmed the long-term stability of the ceramic membrane process, maintaining stable fluxes of approximately 70 L·m −2 ·h −1 and protein rejection exceeding 99% over 140 h of continuous operation. These results demonstrate that ceramic membranes with moderate pore sizes enable an efficient and scalable one-step clarification strategy, providing a robust and industrially viable solution for downstream processing of syngas-derived bioethanol fermentation broths.

Efficient and stable adsorbents are crucial for addressing environmental pollution challenges, especially for the radioactive isotopes 137 Cs in aqueous environments. In this work, a novel composite adsorbent CA-CuPB was manufactured via the thermally induced phase separation (TIPS) method, aiming to remove Cs + from wastewater. CA-CuPB possesses a distinct bi-continuous and interconnected 3D porous network structure, which is characteristic of the Spinodal Decomposition (SD) mechanism in TIPS. Experiments show that the adsorbent CA-CuPB has excellent adsorption performance for Cs + , achieving a removal rate of 96% and an adsorption capacity of 198.06 mg/g in 60 min at pH =7. The adsorption behavior is well fitted by the pseudo-second-order model at 298.15, 308.15, 318.15 and 328.15 K and the Langmuir model ( R 2 = 0.9763, q max = 282.53 mg/g), and the adsorption process is endothermic (∆ H 0 = 20.1784 kJ·mol −1 , ∆ S 0 = 101.4561 J·mol −1 ·K −1 , ∆ G 0 < 0 kJ·mol −1 ). Moreover, CA-CuPB showed high selectivity toward Cs + under the concomitant ions of Na + , K + , Ca 2+ and Mg 2+ , and excellent reusability with at least thirty consecutive adsorption-desorption cycles using ammonium chloride as the eluent. The adsorption mechanism of CA-CuPB toward Cs + is confirmed to be ion exchange by experimental data and DFT calculations. Further, fixed-bed adsorption experiments can achieve an adsorption deficiency of 85.42% when the column height is 30 cm, and the adsorption process is described by the Thomas and BDST models with high accuracy. Neither macroscopic swelling nor structural collapse was observed for the column in 45 days of soaking. Therefore, the new composite adsorbent CA-CuPB holds substantial potential for the rapid and efficient sequestration of Cs + from aqueous wastewater systems.

The escalating demand for nickel driven by electric vehicles and renewable energy storage has led to dual challenges of environmental pollution and resource sustainability. Herein, we report the synthesis of hydroxyapatite nanowires (HAPNWs) via a biomimetic solvothermal approach, positioning them as a rapid-uptake and eco-friendly adsorbent for targeted Ni2+ removal and recovery. The unique interwoven nanowire structure endowed the material with a high specific surface area (18.02 m 2 /g) and abundant mesopores, resulting in ultrafast adsorption kinetics, reaching equilibrium within only 4 min—significantly outperforming conventional adsorbents. The adsorption process, well-described by the pseudo-second-order and Langmuir models, was identified as monolayer chemisorption. A comprehensive mechanistic study, combining XPS, FT-IR, and XRD analyses, revealed that the adsorption proceeds via a synergistic effect of ion exchange (Ca 2+ /Ni 2+ ), surface complexation with phosphate/hydroxyl groups, and partial reduction. The HAPNWs exhibited exceptional selectivity for Ni 2+ over competing ions like Li + and Mg 2+ , which is crucial for treating complex waste streams such as battery recycling effluents. Furthermore, the adsorbent demonstrated excellent reusability, with a high Ni 2+ recovery efficiency of 92% using dilute HCl. This work highlights an operationally simple inorganic adsorbent emphasizing minute-scale Ni 2+ capture and acid regeneration for nickel recovery in a resource-recovery context.
