The traditional polymer-induced risks have gradually come into public view. Polysaccharides and their derivatives have shown potential in replacing traditional polymers. However, polysaccharide-derived materials generally exhibit a single function, limiting their application. Here, cellulose acetate-based composite films were developed by integrating Kraft lignin (KL). The resultant films not only retain the UV resistance and antioxidation properties of lignin but also possess the exceptional swelling resistance, thermal stability, and mechanical performance of cellulose acetate (CA). The sample CAL3 has shown high blocking properties of 95% and 100% at the UVA and UVB regions, respectively. In terms of mechanical performance, the CAL3 has an elongation at break of 75%, tensile strength of 53 MPa, and Young's modulus of 70.7 MPa. After 240 h of UV irradiation, all composite films maintained stability in mechanical performance, transparency, and UV-blocking properties. Such versatile composites hold potential in various fields, including construction, daily protection, plastic packaging, agriculture, and beyond.

The thermomechanical properties of Spiro-graphene nanosheets (GNSs) are investigated using non-equilibrium molecular dynamic (NEMD) simulations, focusing on elastic modulus, ultimate stress, toughness, and thermal conductivity (TC). The effects of dimensions, layers, temperature, and vacancy defects are examined. Spiro-graphene's structural symmetry results in identical mechanical properties along armchair and zigzag directions, with stress-strain curves showing ductile fracture behavior. Size-dependent properties reveal a decrease in Young’s modulus and ultimate stress with increasing side length, converging to 456 GPa, attributed to reduced edge effects and increased stress concentrations. TC increases with side length, stabilizing at 12.45 W/mK due to reduced phonon boundary scattering. Increasing layers from 1 to 5 reduces Young’s modulus, converging to 474.6 GPa, and decreases TC to 6.66 W/mK due to enhanced interlayer phonon scattering and van der Waals interactions.

Oily wastewater represents a serious threat to public health and ecological systems, necessitating the development of innovative strategies to overcome the inherent single-wettability limitation of conventional oil-water separation materials. Here, we present a straightforward method for fabricating pH-responsive composite membranes through hydrophobic modification and nanostructure assembly on robust polypyrrole substrates. The resulting membrane demonstrates a remarkable reversible transition between hydrophilic/underwater superoleophobic and superhydrophobic/superoleophilic states, triggered by pH modulation. This transformation is driven by the pH-induced structural reorganization of fluorinated chains in PFOTs, accompanied by dynamic changes in surface chemical composition. Owing to this unique switching behavior, the membrane achieves on-demand separation of both heavy and light oil/water mixtures, with separation efficiencies of 98.6 % in acidic environments and 93.4 % in alkaline environments, and corresponding fluxes of 50.5 L m⁻2 h⁻1 and 68.8 L m⁻2 h⁻1, respectively. Notably, the membrane maintains stable performance over 50 cycles and 30 cycles under acidic and alkaline conditions, respectively. This intelligent membrane with dual separation modes exhibits significant potential for advanced applications in wastewater treatment and oil extraction, offering a versatile and efficient solution for addressing complex oil-water separation challenges.
含油废水对公共卫生和生态系统构成严重威胁，需要开发创新策略来克服传统油水分离材料固有的单一润湿性限制。在这里，我们提出了一种直接的方法，通过疏水修饰和纳米结构组装在坚固的聚吡咯基底上制造ph响应复合膜。所得膜在pH调节下表现出亲水性/水下超疏油性和超疏水性/超亲油性之间的显著可逆转变。这种转变是由ph诱导的PFOTs中氟化链的结构重组驱动的，伴随着表面化学成分的动态变化。由于这种独特的切换行为，膜可以按需分离重油和轻油/水混合物，在酸性环境中分离效率为98.6%，在碱性环境中分离效率为93.4%，相应的通量分别为50.5 L m⁻2 h毒血症和68.8 L m⁻2 h毒血症。值得注意的是，在酸性和碱性条件下，膜分别在50次和30次循环中保持稳定的性能。这种具有双重分离模式的智能膜在污水处理和采油方面具有巨大的应用潜力，为解决复杂的油水分离问题提供了一种多功能和高效的解决方案。

Biofouling, defined as the accumulation of microorganisms on submerged surfaces, adversely impacts marine transportation. Developing effective antifouling agents has become an effective solution. Cerium oxide (CeO2) nanoparticles have emerged as a promising alternative to toxic copper-based biocides due to their intrinsic haloperoxidase (HPO)-like activity, which can catalyze the formation of hypobromous acid (HOBr) from bromide ions abundantly present in seawater, thereby inhibiting biofilm formation. Graphene oxide (GO) complements this action by physically disrupting bacterial membranes. This study investigates the influence of GO content in CeO2/graphene oxide (GO-CeO2) composites on the HPO-like activity and antifouling efficacy of CeO2 particles. The experimental results indicate that GO had a slight effect on the HPO-like activity of CeO2 since it reduced Ce3+ site content. The 6 wt.% GO-CeO2 composite exhibited outstanding antibacterial and antibiofilm activity, attributable to its high zeta potential, improved dispersibility, and synergistic effects between GO and CeO2. The remarkable results demonstrated that the GO-CeO2 composite is a highly promising, eco-friendly candidate for marine antifouling coatings.

This study presents a surface modification technique for aluminum alloys designed for thermal management in outdoor electronic enclosures. A multilevel rough structure was constructed on the alloy surface via a combination of sandblasting and etching, followed by the grafting of perfluorodecyltriethoxysilane (PFTEOS). The treated sample exhibited an infrared emissivity of 0.8951 and a superhydrophobic character, with a water contact angle of 153.63° ± 0.9° and a sliding angle of 3.2° ± 0.2°. These properties conferred excellent self-cleaning ability and resistance to water flow impact. Under testing with a 3 W heat source and direct sunlight, the modified enclosure achieved an average internal temperature reduction of 6.4 °C compared to an untreated enclosure, while maintaining a high thermal conductivity of 157.88 W·m⁻¹·K⁻¹. The results demonstrate that this method effectively enhances radiative heat dissipation without compromising thermal conductivity.

The optimized surface chemistry and engineered interfaces of hybrid nanostructures offer an effective path forward for the development of electrochemical energy conversion and storage. In the present work, a ternary CoWO4/MXene@CNTs composite was fabricated through a hydrothermal-ultrasonication method to construct a conductive, oxygen-vacancy-rich scaffold. The successful integration of CoWO4 with MXene nanosheets and CNTs, along with the generation of W⁵⁺/W⁶⁺ defect states and oxygen vacancies that improve the charge‐carrier density to 4.18 × 10²⁴ cm⁻³, was further confirmed through structural and XPS analyses. More importantly, the composite demonstrated an enlarged electrochemically active surface area of 345.71 cm², significantly higher than that of the pristine CoWO₄ electrode (260 cm²) and the binary CoWO4/MXene composite (274 cm²). Electrocatalytic testing shows that interface engineering significantly enhances reaction kinetics. The composite requires only 78 mV for HER and 168 mV for OER to reach 10 mA cm⁻², with Tafel slopes of 53 mV dec⁻¹ for HER and 49 mV dec⁻¹ for OER, respectively. The observed 11.16 Ω charge-transfer resistance, together with lower solution resistance, indicates that the MXene-CNTs network enables faster electron exchange at the interface due to its highly conductive structure. In supercapacitor measurements, CoWO4/MXene@CNTs exhibits a high specific capacitance of 1980 F g⁻¹ at 1 A g⁻¹, outperforming CoWO4 (863 F g⁻¹) and CoWO4/MXene (1282 F g⁻¹). At 100 mV s⁻¹, the charge-storage mechanism displays a balanced contribution of 53.02 % diffusion-controlled and 46.98 % capacitive processes, supported by prolonged discharge times of up to 1980 s. In all, the interface modulation, oxygen-vacancy generation, and conductive pathways from MXene-CNTs raise the catalytic and capacitive performances of CoWO4 by several steps and position the composite as a promising multifunctional material for energy applications.

This work presents the results of formation of bioactive coatings on Mg-Mn-Ce alloy by plasma electrolytic oxidation (PEO) with subsequent modification with vitamin K2 and polydopamine (PDA). The formed porous coating contained calcium phosphates, which indicates improved biocompatibility. The presence of calcium and phosphorus as well as organic compounds in the coatings was confirmed by XRD, EDS and SEM equipped with FIB. During long-term exposure of the samples to SBF, a gradual decrease of Ca2+ and PO43- in the solution was revealed, as well as a formation of biomimetic hydroxyapatite on the samples surfaces. This demonstrates the effectiveness of the created coatings as osteo-compatible ones due to the possible formation of new centers of bone tissue. A detailed study of the corrosion of the materials in physiological environments by volumetry and EIS confirms successful inhibition of dissolution of Mg alloy, opening up new possibilities for the use of Mg implants in orthopedics.

Slippery lubricant-infused porous surfaces (SLIPS) have shown considerable promise for durable anti-icing applications, particularly when using high-viscosity lubricants. Nevertheless, high-viscosity lubricants tend to accelerate the propagation of fine frost crystals across the SLIPS. Herein, a chemical modification strategy for high-viscosity silicone oil-specifically by incorporating 2 wt% silane-is proposed to enhance its frost resistance. The anti-frosting performance and durability of SLIPS fabricated with the modified silicone oil were systematically evaluated, with comparative analyses performed against SLIPS infused with unmodified lubricants of different viscosities and alternative lubricant types. Results indicate that the lubricant modification retains the excellent liquid-repellent and anti-icing capabilities inherent to SLIPS. More notably, the modified SLIPS demonstrates remarkable anti-frosting performance, outperforming counterparts infused with low-viscosity lubricants—almost no icing was observed after 1.5 h under low-temperature and high-humidity conditions. The modified silicone oil is covered with a large number of non-polar long-chain alkyl groups, which reduces the intermolecular interactions between the slippery surface and water. Furthermore, the modified SLIPS inherit the superior durability of high-viscosity lubricants, exhibiting an ice adhesion strength of merely 12.4 kPa even after 20 icing/deicing cycles. Additionally, the modified silicone oil endows SLIPS with better anti-frosting performance and durability compared to other lubricant types. This study provides valuable theoretical guidance for lubricant selection in the development of high-performance anti-icing SLIPS.

This study addresses the long-term corrosion protection needs of 5052 aluminum alloy in marine environments. An optimized anodic oxidation process was employed to fabricate a high-porosity and strongly adherent anodic aluminum oxide (AAO) template on the 5052 aluminum alloy substrate. Subsequently, Zn2+, Mg2+, and Al3+ were co-precipitated in situ within the AAO nanopores and on its surface, resulting in the formation of a compact and continuous ZnMgAl-layered double hydroxide (LDHs) layer. The results revealed that ZnMgAl-LDHs nanosheets grew vertically and interlocked on the AAO film surface, exhibiting the characteristic morphology of LDHs coatings. Combined XRD, FTIR, and XPS results further confirmed the chemical composition of the LDHs and revealed chemical bonding at the AAO/LDHs interface. Electrochemical measurements demonstrated that the AAO/ZnMgAl-LDHs composite coating achieved an exceptionally low corrosion current density of 9.42 × 10–10 A·cm–2 and a high charge transfer resistance of 1.08 × 108 Ω·cm2, confirming its exceptional corrosion resistance. This performance surpassed that of both the bare AAO film and the AAO/MgAl-LDHs composite coating. Moreover, the LDH coatings exhibited outstanding resistance to both salt spray corrosion and long-term immersion corrosion. The developed process demonstrates compatibility with existing anodizing production lines, eliminating the need for complex post-treatment. This positions it as a promising alternative to conventional chromate/rare earth conversion coatings, paving the way for green and long-lasting applications of aluminum alloys in shipbuilding, offshore wind power, and related marine sectors.

Molybdenum disulfide (MoS2), a two-dimensional transition-metal chalcogenide, is a promising material for photoelectrochemical (PEC) water splitting but is limited by its low stability and weak photoactivity. In this study, we address these challenges by constructing α-Fe2O3/MoS2 (FM) heterostructures, synthesized via RF magnetron sputtering of MoS2 nanosheets onto hydrothermally grown α-Fe2O3 nanoparticles. Comprehensive structural and compositional analyses confirm the successful formation of the heterostructures, with XRD, TEM, Raman, FESEM, and XPS revealing enhanced crystallinity and optimal interface formation. The FM-20 photoanode, fabricated with a 20-min MoS2 deposition, exhibits a significantly improved photocurrent density of 1.85 mA/cm2 at 1.65 V vs. RHE, and achieves an applied bias photon-to-current efficiency (ABPE) of 1.01%, 25-fold to pristine α-Fe2O3. This enhancement is attributed to improved light absorption, efficient charge separation, and reduced recombination, as evidenced by photoluminescence and electrochemical impedance spectroscopy. The FM-20 photoanode also demonstrates excellent operational stability over 4000 s, underscoring its potential for sustainable hydrogen production. These findings highlight the effectiveness of α-Fe2O3/MoS2 heterostructures as robust and efficient photoanodes for PEC water splitting applications.
二硫化钼（MoS2）是一种二维过渡金属硫族化合物，是一种很有前途的光电化学（PEC）水分解材料，但其稳定性低，光活性弱。在这项研究中，我们通过在水热生长的α-Fe2O3纳米颗粒上通过射频磁控溅射将MoS2纳米片合成α-Fe2O3/MoS2 （FM）异质结构来解决这些挑战。综合结构和成分分析证实了异质结构的成功形成，XRD， TEM, Raman， FESEM和XPS显示了增强的结晶度和最佳的界面形成。采用MoS2沉积20 min制备的FM-20光阳极，在1.65 V下光电流密度显著提高至1.85 mA/cm2，应用偏压光子电流效率（ABPE）达到1.01%，是原始α-Fe2O3的25倍。正如光致发光和电化学阻抗谱所证明的那样，这种增强归因于光吸收的改善，有效的电荷分离和减少的复合。FM-20光阳极在4000秒内也表现出出色的运行稳定性，强调了其可持续制氢的潜力。这些发现强调了α-Fe2O3/MoS2异质结构作为PEC水分解应用中稳健高效的光阳极的有效性。
