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.

Polyamide (PA) reverse osmosis thin-film composite (RO TFC) membranes constructed via interfacial polymerization (IP) process have been extensively employed in seawater desalination, and the crosslinking degree and thickness of PA layer play crucial role on their practical performance. Herein, an in-situ surface segregation strategy was adopted to fabricate hydrophilic and porous substrate with dopamine (DA) as surface segregation agent, thereby effectively regulating the IP process for enhanced desalination. During substrate fabrication process, DA self-polymerized to generate polydopamine (PDA), subsequently PDA segregated into surface, which could enrich amine monomers in the aqueous phase and slow their diffusion toward the organic phase, through hydrogen bonding and π-π interactions between PDA and amine monomers. Accordingly, the crosslinking degree increased from 79.1 % to 89.9 %, particularly improving boric acid rejection from 71.3 % to 88.9 %. Meanwhile, the thickness of PA layer decreased to 48.0 nm. The optimized membrane exhibited a water permeability of 1.91 L m −2 h −1 bar −1 and NaCl rejection of 99.9 %, while maintaining excellent stability over 100 h of continuous operation. Furthermore, the membrane showed outstanding desalination performance for real seawater, demonstrating that fabricating substrate through surface segregation method offered an efficient and easy pathway for high-performance RO membranes.

The H 3 BO 3 added CaAlB 2 O 5.5 ceramics were prepared by solid-state method. Their thermal behavior, phase composition, microstructures, and dielectric properties across both microwave and terahertz frequency ranges were systematically characterized, with a particular focus on exploring their terahertz response. Ceramic samples with the composition CaAlB 2 O 5.5 + x wt% H 3 BO 3 (where x = 0, 2, 4, and 6) were synthesized using solid-state reactions and sintered at temperatures between 940 °C and 1060 °C. With 4 wt% of H 3 BO 3 , the sample shows the lowest secondary phase content and the highest relative density. Whereas, the sample sintered at 980 °C exhibited the best microwave dielectric properties: ε r = 5.8 ± 0.05, Q × f = 41372 ± 1100 GHz (@11.45 GHz), and τ f = -28 ± 2 ppm/°C, as well as an excellent terahertz dielectric property with Q × f = 4.726 × 10 8 GHz (@ 3.14 THz). By careful calculation with DFT, the Debye-Lorentz fitting reveals that lattice polarization and phonon damping dominantly govern the dielectric response from microwave to terahertz frequencies. Finally, the microstrip patch antenna fabricated on the optimized CaAlB 2 O 5.5 ceramic substrate exhibited a peak gain of 6.4 dB and a low return loss (S 11 = -33.72 dB) at a center frequency of 4.86 GHz. CaAlB 2 O 5.5 ceramics deliver high-quality microwave to terahertz dielectric performance and are promising candidates for microwave and terahertz applications.

Addressing the challenges associated with noise pollution problem necessitates the development of composite materials exhibiting both sound absorption and fire resistance under extreme environmental conditions. Conventional foam materials are limited by inadequate heat resistance, insufficient moisture resistance, and suboptimal functionality, rendering them unsuitable for such harsh environments. A new SiO 2 /C/SiBOC ceramic matrix porous sound-absorbing material was fabricated through a combination of sol-gel process, electrospinning, and organic impregnation techniques. Polyurethane foam (PUF) served as a template to establish a porous structure, while the SiBOC ceramic matrix conferred high-temperature resistance, and SiO 2 /C fiber reinforced the mechanical properties. Compared to traditional sound-absorbing materials, the developed composite demonstrates efficient sound absorption at low frequencies (NRC = 0.46) and across a broad frequency range (25–6500 Hz, α > 0.8). Additionally, it exhibits excellent thermal stability at elevated temperatures (up to 1400 °C), low thermal conductivity at room temperature (0.03463 W/m·K), high compressive strength (2.21 MPa), superior moisture resistance (contact angle θ = 101.4°), and a lightweight structure. This study contributes by proposing and validating a new design concept for porous ceramic composites, which can simultaneously balance acoustic, thermal, and mechanical properties as well as moisture resistance, effectively filling the gap in application areas of existing material systems.

Polyurea (PUA) coatings are widely used in protective applications but are limited by inherent flammability and reduced mechanical integrity from traditional flame retardants. Herein, we report a facile supramolecular modification of black phosphorus (BP) nanosheets, combining chitosan-assisted ball milling with melamine borate co-assembly to yield the CNB@BP nanohybrid. This nanohybrid showed excellent compatibility and dispersibility in the PUA matrix, providing nanocomposites with synergistic improvements in mechanical, anti-impact, thermal stability, and flame-retardant properties. Notably, 1 wt% loading increased tensile strength by 82.35% and impact resistance for aluminum alloy by 51.42%. At 3 wt% loading, peak heat release rate and total heat release dropped by 26.40% and 21.88%, respectively, with effective suppression of smoke and toxic gas emissions. These fire safety improvements arose from a P-N-B synergistic mechanism across two phases: catalytic charring and physical barriers in the condensed phase, plus radical scavenging and gas dilution in the gas phase. This supramolecular engineering approach thus offers a new paradigm for low-dose nanohybrids, enabling advanced PUA elastomers with balanced mechanical strength and fire safety.

Rigid polyurethane foam (RPUF) is extensively employed in construction and transportation for its superior insulation and structural integrity. However, its inherent high flammability restricts its utility across various applications. The excessive use of traditional flame retardants can lead to a reduction in the physical properties of materials and generate toxic by-products during combustion. To address this challenge, we developed an innovative flame-retardant system for RPUF, using nitrogen-containing polyols synthesized from formaldehyde and melamine, and replacing traditional polyols with 2-methyl-1,3-propanediol (MPD), alongside boron-containing polyols derived from glycerol and boric acid. The incorporation of nitrogen- and boron-containing polyols at a 1:1 ratio has markedly raised the limiting oxygen index of RPUF from 19.1 % (pure RPUF) to 26.8 % while maintaining its mechanical properties, with the compressive strength ranging from 0.48 MPa to 0.50 MPa. Compared to traditional polyether polyols, MPD offers an environmentally friendly alternative by reducing toxic byproduct emissions during combustion, providing a safer profile in fire scenarios. Additionally, compared to pure RPUF, the total heat release and total smoke production were significantly reduced by 68.8 % and 52.4 %, respectively. Thermogravimetric analysis demonstrated enhanced thermal stability and char-forming ability, further confirmed by scanning electron microscopy. These findings suggest that the newly developed system has great potential for enhancing RPUF's flame retardancy and smoke reduction while maintaining its mechanical properties at the same time.

The conventional approach of enhancing the strength of titanium alloys and their composites through mechanical processing to induce dislocations often leads to compromised ductility. In recent years, structural design strategies have stimulated the exploration of the material community towards deformation mechanisms and their impact on mechanical properties. Herein, we introduce the {10 1 ‾ 2} twinning to the B@Gr/TC4 composites, which were synthesized using ball milling, spark plasma sintering, hot rolling, and heat treatment processes. These composites are reinforced by in-situ formed TiC and TiB hybrid phases, achieving a high ultimate tensile strength (UTS) of 1424 MPa and fractured elongation (FE) of 13%, which are superior to those of TC4 alloy (with its UTS of 984 MPa and FE of 12%) and Gr/TC4 composite (with its UTS of 1325 MPa and FE of 12%). The enhanced strength of the composite is primarily attributed to the grain refinement and dislocation strengthening effects contributed by the high percentage of small-angle grain boundaries pinned by TiC and TiB hybrid phases. Furthermore, the twinning-induced strain softening effect is identified as the key mechanism for maintaining exceptional ductility. This study provides an effective structural strategy to simultaneously improve the strength-ductility of Ti matrix composites.

The effects of different milling (dry, tempered dry and wet) methods and varieties ( indica and japonica ) of brown rice (BR) on the physicochemical properties of BR flours (BRF) and eating quality of extruded rice noodles (ERN) were investigated. Results showed that tempered dry- and wet-milled BRF showed smaller particle sizes, lower damaged starch (DS) content and water solubility index, as well as higher L∗ value and pasting viscosity. Under different milling methods, indica BRF exhibited lower DS content, better pasting properties. In addition, extrusion treatment promoted the transformation of insoluble to soluble dietary fiber in the ERN, which improved the nutritional value and taste of rice noodles. The ERN prepared with wet milling indica BRF showed lower broken stripe rate (1.67%), cooking loss (7.10%), and higher hardness (2433.73 g), demonstrating optimal product quality. Principal component analysis and correlation analysis showed that the particle size, DS content, and water absorption index of BRF were the key factors influencing the quality of ERN. These results provide a scientific basis for industrial production of BRF and ERN in the future.

Chlorogenic acid-loaded coffee shell-derived carbon dot nanoparticles (CGA/CSCD NPs) with enhanced antibacterial photodynamic therapy (aPDT) activity were developed, exhibiting strong fluorescence (~400 nm), a graphite-like structure, and around 3 nm size. The nanoparticles achieved efficient ROS generation and bacterial enrichment, showing superior antibacterial efficacy and biocompatibility. Applied to Carassius auratus , Megalobrama amblycephala , and Dicentrarchus labrax under 4 °C storage, the CGA/CSCD NPs-aPDT treatment inhibited 99% of bacterial growth over 7 days, maintaining counts at 10 4 –10 5 CFU/g. The treatment significantly slowed pH rise, inhibited TVB-N accumulation, and reduced lipid oxidation by 2–3 times compared to controls. Furthermore, the nanoparticles preserved fish quality by minimizing moisture loss and maintaining color stability and texture (hardness and chewiness). These results demonstrate that CGA/CSCD NPs-aPDT provides a sustainable and effective strategy for delaying spoilage and extending the shelf life of aquatic products during cold storage.

Electrolysis of seawater presents a sustainable pathway to green hydrogen production, utilizing both the abundant source of seawater and from renewable energy. Yet, the slow anode oxygen evolution reaction (OER) necessitates alternative, where urea oxidation reaction (UOR) intermediate shows promise due to its favorable thermodynamic potential. In this work, we report a simple synthetic method to prepare an iron-cobalt (Fe–Co) electrocatalyst directly onto Ni foam via cyclic voltammetric (CV) electrodeposition. The catalyst demonstrates outstanding UOR activity in 1 M KOH + 0.33 M urea seawater, achieving low potentials of 1.335 V and 1.458 V at 10 and 100 mA·cm −2 , respectively, a Tafel slope of 133.8 mV·dec −1 , and a charge-transfer resistance (Rct) of 0.81 Ω. It exhibits a high mass activity of 13.24 mA·mg −1 at 1.45 V and maintains stable operation for over 70 h at 10 mA·cm −2 . The excellent UOR performance, coupled with the electronic structure reconstruction induced by Co doping, suggests the formation of more active sites with optimized electronic configurations, which favors the key steps of urea oxidation. Additionally, the superhydrophilic surface of the electrocatalyst Fe–Co permits quick and complete electrolyte infiltration, which creates a highly accessible reaction interface and therefore increases catalytic activity. Given its low-cost synthesis, simple preparation method, remarkable UOR activity, and long-life operation stability, the electrocatalyst Fe–Co is one of the most promising candidates to enhance urea-assisted, sustainable electrolytic hydrogen production technologies.

The practical application of aqueous supercapacitors is constrained by the balance between cycle life and power characteristics. This study develops a composite electrode based on hexagonal boron nitride/carbon nanotubes (h-BN/CNTs), featuring fabrication processes through thermal annealing and electrostatic assembly. The material ingeniously combines the chemical inertness and structural stability of h-BN with the conductive network of CNTs, successfully constructing an electrode with highly stable mechanical and electrochemical interfaces. The assembled symmetric supercapacitor demonstrates excellent long-term operational reliability, maintaining over 90% stability after 10,000 charge-discharge cycles while exhibiting outstanding rate performance. The core value of this work lies in its application to h-BN platforms for high-power, high-frequency optical devices, successfully transforming it into a high-performance electrochemical energy storage component. The material has a high power density of 600 W/kg and a fairly good energy density of 13.6 Wh/kg in the symmetric two-electrode test. This device construction strategy based on a unified core material system creates compatibility advantages for material substrate and process-level integration with high-power optical devices, providing a material foundation for developing next-generation optoelectronic integrated systems.

Boron is both an essential trace element and an important industrial raw material, rendering its efficient extraction from brines highly valuable. This study synthesized UiO-66-p-PhOH (phenolic hydroxyl) and UiO-66-p-AlOH (aliphatic hydroxyl) by grafting ortho-hydroxyl functional groups onto UiO-66-p, achieving adsorption capacities of 2.28 and 3.65 mmol/g in 4000 mg/L B solution, respectively. Both adsorbents reached adsorption equilibrium within 20 mins, enabling efficient boron extraction. UiO-66-p-OHs maintained structural stability in complex brines and exhibited higher selectivity coefficients ( K B were between 1.5 and 18.1) compared to that in binary solutions ( K B were between 0.09 and 5.2). Moreover, boric acid bound by each phenolic hydroxyl was 2.5–4.3 times of aliphatic hydroxyls. DFT calculations revealed that phenolic hydroxyls exhibited stronger affinity, with an adsorption energy of −29.01 compared to −27.24 kJ/mol for aliphatic hydroxyls. UiO-66-p-PhOH and UiO-66-p-AlOH could be regenerated through a simple water-washing and mild-acid soaking process, achieving regeneration rates of 77.5% and 95.4%, respectively. This work demonstrated the boron extraction efficiency of phenolic hydroxyl and aliphatic hydroxyl groups in saline water, providing important reference for designing boron adsorbents under high salinity conditions.
