A series of organopolysilazane (OPSZ) composite coatings were synthesized via a grafting reaction between OPSZ and epoxy resin, which were applied to protect the surfaces of combustible cartridge cases. The chemical compositions were characterized by Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy. The results of heat-resistance tests indicated that the optimum OPSZ composite coating could prevent the combustible cartridge cases from burning for 175.56 s at 250 °C. The glass transition temperatures (Tg) of the OPSZ composite coatings were in the range of 254.7–454.0 °C. The results indicated that the OPSZ composite coatings could effectively improve the heat resistance of combustible cartridge cases. Based on scanning electron microscopy images after saltwater exposure tests, the saltwater absorption rate, and the water contact angle, the OPSZ composite coatings could effectively improve the environmental adaptability of combustible cartridge cases. In this study, the ceramic precursor OPSZ, as a protective material, provides a novel way to fabricate various coatings to protect combustible cartridge cases from high temperatures, environmental humidity, and corrosive air.

Our study intended to exploit the magnetic property and the metal species of tin ferrite (SnFe2O4), the continuous redox cycle of FeCoNi-layered ternary hydroxides (FeCoNi-LTH), and the storage-release effect of the β-cyclodextrin (β-CD) to construct an advanced Fenton-like catalyst to degrade tetracycline (TC). The experimental results implied higher adsorption% and the degradation% of TC reached 34.29 % and 95.38 % throughout 90 min at the optimum conditions: pH = 7, 10 mg of SnFe2O4/2FeCoNi-LTH/β-CD, 50 mg/L of H2O2, and 50 mg/L of TC. The kinetic study proceeded on the acquired data from studying the degradation of various concentrations of TC using First-order and Second-order, implying the suitability of Second-order to model the TC degradation reaction. The scavenging test was executed using quenching agents to superoxide and hydroxyl radicals to identify which one is the predominant reactive oxygen radical. The adsorption and Fenton-like degradation mechanisms of TC by SnFe2O4/2FeCoNi-LTH/β-CD were presumed using XPS. The obtained intermediates during the Fenton-like degradation of TC were determined by GC–MS. The durability and reusability of SnFe2O4/2FeCoNi-LTH/β-CD were confirmed by doing the recycling test for five catalytic TC degradation runs, clarifying that the degradation% of TC was about 75 % after the 5th run. The metal leaching study was performed on the SnFe2O4/2FeCoNi-LTH/β-CD composite to prove that it does not form secondary contaminants. Finally, SnFe2O4/2FeCoNi-LTH/β-CD exhibited a promising degradation activity towards TC with an excellent recycling property for five catalytic runs and high chemical stability. In addition, SnFe2O4/2FeCoNi-LTH/β-CD elucidated remarkable degradation efficiency towards other pharmaceutical residues, cationic and anionic dyes, and nitro-aromatic compounds, indicating the wide applicability of the as-fabricated composite.

Counterfeiting is a quite huge threat to our modern society. Anti-counterfeiting technology based on photoluminescent (PL) materials has been considered as a powerful solution to overcome this challenge due to their unique advantages such as facile design, high-level security, and fast authentication. However, most of present PL materials suffer from high-cost, low-stability or toxic. In this work, an environmental-friendly I−III−VI quantum dots (f-Ag-In-Zn-S QDs) was designed and synthesized, which shows similar optical properties with Ag-In-Zn-S QDs without modification. The novel QDs with low-surface energy modification was adopted to prepare stable superhydrophobic and luminescent surfaces combining modified silica (f-SiO2) by simple spraying method. With varying excitation wavelength from 380 to 500 nm, the PL peak of multifunctional surfaces redshifted from 504 to 587 nm. Correspondingly, orange and red photoluminescence patterns were clearly observed when the ant-counterfeiting coatings were irradiated by UV light with 365 and 395 nm, respectively. Moreover, the intentionally designed similar low surface energy components from the outer of f-Ag-In-Zn-S QDs and f-SiO2 nanoparticles made them uniformly disperse on the substrate and constructed micro/nano-scale hierarchical porous structure, which provided same superhydrophobic and luminescent properties on the entire surface of dual-functional coating. Furthermore, the superhydrophobicity played a protective role in making sure that the dual-functional coating still can work even they were applied by different harsh treatments including ultrasonic oscillation, sandpaper abrasion, boiling water jet impacting, acid or alkali solution immersion, ultraviolet irradiation, heating/cooling. Therefore, this simple, green and low-cost technology provided a useful example for designing and fabricating stable ant-counterfeiting materials.

By applying density functional theory (DFT)/implicit model calculations we demonstrate that the minimum voltage required for adsorption of water molecules on Pt(111) surface could be evaluated in a good agreement with experiment (0.4 V vs. SHE (standard hydrogen electrode)). We also show that reliance on a computationally determined potential of SHE with respect to vacuum level is more appropriate than using the experimental range of values. Although the value of this computed SHE potential differs substantially from the experiment (3.3 V versus 4.4–4.8 V as found experimentally) the calculated voltage of water adsorption is in a very close agreement with experimental measurements due to error cancelation in DFT calculations of the energy differences (i.e. water on the Pt(111) surface versus water in solution). We attribute this error to inherent inaccuracy of DFT in evaluation of the materials work functions. We also show that upon hydration of a Pt surface there exists a peculiar non-monotonic change of a potential upon charging of a slab in contrast to monotonic relation for a clean Pt surface, which we explain by modification of water binding mechanism with changing of a charge state of Pt surface.

We demonstrate a method for the detection of Ziram in water by using the adsorption properties of UiO-66(Ce) metal-organic framework (MOF) combined with the surface-enhanced Raman scattering (SERS) substrate of precious metal nanoparticles. The traditional UiO-66 is based on Zr as the metal center. After replacing the Zr metal center with Ce, the synthesized UiO-66(Ce) has short aging, high efficiency, low energy consumption, and energy saving. Furthermore, by adding P123, UiO-66 is modified to have a structure similar to the durian shell spine, which can provide more composite sites for metal nanoparticles. Thus, more SERS hot spots are generated. The combination of AuNPs with UiO-66(Ce) has been confirmed by XRD, XPS, and other characterization and analysis techniques. The Raman probe molecule R6G was used as an evaluation tool to evaluate the performance of this SERS substrate. The results showed that the relative standard deviation (RSD) of the substrate was as low as 8.96 % at a concentration of 10–6 M of the R6G solution, and the substrate demonstrated high stability. Finally, the substrate was applied for the detection of ziram in lake water, achieving a detection concentration of 10–8 M, an enhancement factor of 2.57 × 105, and a detection limit as low as 5.21 × 10–9 M, demonstrating excellent sensitivity and enabling efficient trace pollutant detection in complex water environments.

In this study, we investigated the fabrication and photocatalytic performance of ZnBi2O4@Bi2WO6 nanocomposites for the degradation of organic pollutants. The nanocomposites were synthesized via a hydrothermal method followed by ultrasonic treatment, resulting in a unique composite structure. X-ray diffraction (XRD) confirmed successful material synthesis, and scanning electron microscopy (SEM) revealed the morphologies of Bi2WO6 nanoflowers and ZnBi2O4 nanocubes, with the composites exhibiting a hybrid network-like structure. UV–visible spectroscopy showed a significant redshift in the optical absorption edge, indicating that ZnBi2O4 incorporation effectively reduced the band gap of the nanocomposite, enhancing its visible light absorption. Photoluminescence (PL) spectroscopy demonstrated that the nanocomposites promoted efficient charge separation and minimized recombination, critical factors for improved photocatalytic performance. Under visible light, the ZnBi2O4@Bi2WO6 nanocomposites achieved a degradation efficiency of 96.8 % for alizarin red S (ARS), following pseudo-first-order kinetics. The composites also exhibited excellent stability, with only a 6.05 % loss in activity after five degradation cycles, confirming their long-term durability. Trapping experiments identified hydroxyl radicals (·OH), holes (h+), and electrons (e–) as active species in the degradation mechanism. Overall, ZnBi2O4@Bi2WO6 nanocomposites show strong potential as efficient and stable photocatalysts for removing hazardous organic pollutants from wastewater, offering a sustainable solution for environmental cleanup.

A novel amine-functionalized cerium ferrite biochar (NCFBC) was firstly synthesized by microwave-assisted anaerobic carbonation and subsequently applied for the adsorption of V(Ⅳ) and V(V) in water in the work. In comparison with other biochars that have been synthesized (e.g., BC, CFBC, and NCFBC), NCFBC demonstrated superior vanadium (V) adsorption properties. The V adsorption by NCFBC was a monolayer, homogeneous process of chemical and physical co-action through adsorption kinetics and isotherm modeling. The maximum V(Ⅳ) and V(V) adsorption by NCFBC, as predicted by the Langmuir model, was 345.72 mg/g and 178.97 mg/g, respectively. The surface structural characterization revealed that the amine-functionalized NCFBC exhibited an increased particle size, specific surface area, pore size, and pore volume. The XPS and FTIR characterization results demonstrated that CO/C=O functional groups on the NCFBC surface exhibited a preference for binding to V(V) during the adsorption process. However, the -NH2 functional group demonstrated a preference for binding to V(Ⅳ). The adsorption mechanism of NCFBC for V included functional group complexation, surface precipitation, pore adsorption, and electrostatic attraction. The findings from the renewable cycle test, anion interference assessment, various metal removal trials, and real-world environmental applications highlight the remarkable stability of NCFBC during the metal removal process. Its efficiency in eliminating diverse metals in practical settings underscores its vast potential for widespread utilization.

Oxygen modification on the interface is crucial to improve the mechanical strength of graphene/copper (Gr/Cu) composites. However, the existing form of interface oxygen and the strengthening mechanisms are not well understood. In this work, first principles calculations are performed to investigate the mechanisms for oxygen modification in the Gr/Cu interface and the influences on the bonding behaviors. It is found that oxygen modification could increase the separation work of the Gr/Cu interface by about 300 %, and thus enhance the interface bonding substantially, owing to the formation of strong ionic bonds between O and Cu. As a result, the theoretical tensile strength is increased from 3.29 GPa to 4.67 GPa by 42 %. Changes in charge density and atomic spacing at the interface during stretching suggest that fracture occurs along the interface between graphene and O. This study provides valuable insights into the design of high-strength Gr/Cu composites.

In this work, first principles calculations are performed to investigate the mechanisms for oxygen modification in the Gr/Cu interface and the influences on the bonding behaviors. It is found that oxygen modification could increase the separation work of the Gr/Cu interface by about 300 %, and thus enhance the interface bonding substantially, owing to the formation of strong ionic bonds between O and Cu. As a result, the theoretical tensile strength is increased from 3.29 GPa to 4.67 GPa by 42 %. Changes in charge density and atomic spacing at the interface during stretching suggest that fracture occurs along the interface between graphene and O. This study provides valuable insights into the design of high-strength Gr/Cu composites.</div></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":"58 ","pages":"Article 105866"},"PeriodicalIF":5.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strain sensors based on crack-sensitive structures have gained attention for their exceptional sensitivity. However, the geometry of the crack structures significantly impacts the balance between sensitivity and strain range, while the controllable formation of such cracks remains a challenge, often leading to performance variations. Herein, we developed an ultrasensitive strain sensor using a mesh-like polymer-mediated electroless plating (MPMEP) strategy to construct controlled nickel microcrack structures on natural rubber (NR). Poly(acrylic acid) brushes grafted via surface-initiated ATRP on NR served as interfacial layers, ensuring consistent crack morphology. The sensor achieved a high gauge factor of 417, a wide strain range of 50 %, and rapid response/recovery times (46/58 ms), with stable performance over 10,000 cycles. Compared to existing technologies, our MPMEP strategy uniquely combines high sensitivity with scalability. Moreover, its robustness and flexibility position it for wearable applications, including real-time human motion monitoring and health management. This work addresses long-standing challenges in crack-based strain sensors, presenting a reproducible and scalable platform for next-generation flexible electronics.

Aqueous rechargeable Ni-Fe batteries, characterized by substantial theoretical capacity, high power density, ultra-flat discharge plateau, low cost, and exceptional safety features, exhibit promising prospects for large-scale energy storage applications. However, the poor stability and inadequate energy density of Ni-Fe batteries impede their extensive utilization. In this study, a composite electrode material of CoFe2O4@Fe2O3 with a nanoparticle structure was synthesized on iron foam using a simple one-pot hydrothermal method, referred to as Fe-CoFe2O4@Fe2O3. The Fe-CoFe2O4@Fe2O3 electrode demonstrated outstanding electrochemical energy storage performance, thanks to its binder-free feature, large electrochemically active surface area, high conductivity, and favorable nanosheet deformation after cycle process. A remarkable areal specific capacity of 2.30 mAh cm-2 at 5 mA cm-2 was achieved for the Fe-CoFe2O4@Fe2O3 electrode, which is significantly superior to that of the pristine Fe-Fe2O3 (1.11 mAh cm-2) and Fe-CoF2O4 (1.17 mAh cm-2) electrodes. In addition, the Fe-CoFe2O4@Fe2O3 electrode demonstrated exceptional cycle life, maintaining excellent performance over 10,000 cycles. Furthermore, the suitability of Fe-CoFe2O4@Fe2O3 as an advanced anode in a Ni-Fe battery was confirmed by fabricating a Ni-Ni3S2@NiC2O4//Fe-CoFe2O4@Fe2O3 battery, which achieved an impressive energy density of 14.2 mWh cm-3 and exceptional cyclic stability without capacity decay even after 30,000 cycles. To the best of our knowledge, such exceptional durability over extended cycles is rarely reported in Ni-Fe batteries and other rechargeable batteries, suggesting the great potential of this Ni-Fe battery for practical applications.
