An adsorbent that enables the simultaneous adsorption of arsenic and fluorine (As–F) must be urgently developed. To address these issues, wheat straw–derived biochar (XM) was optimised herein by loading Fe and La for obtaining Fe/La–XM composites. The influence of factors such as As–F initial concentration, solution pH and coexisting ions on As–F adsorption by Fe/La–XM was analysed. Results revealed that Fe/La–XM was mesoporous with excellent surface structure and could rapidly adsorb As and F simultaneously in just 5 h. Its adsorption capacities for As and F were 128 and 33 times higher, respectively, compared with those of original biochar. It achieved a remarkable As–F removal rate of 98 % at a pH of 5.0–10.0. The adsorption model strongly conformed to the Langmuir isotherm model and was consistent with the pseudo-second-order kinetic equation. The adsorption process was governed by intra-particle diffusion, surface adsorption and other mechanisms. During this process, As and F exhibited antagonistic effects and underwent competitive adsorption. Fe/La–XM primarily relied on electrostatic and chemical adsorption processes at a pH of &lt;6.43. At a pH of &gt;6.43, chemical adsorption was dominant. In addition, As exhibited strong tendency to form stable Fe–O–As ligand complexes. Meanwhile, La readily formed high-strength La–F coordination bonds with F, ultimately leading to the adsorption of LaF<sub>3</sub> on the surface of Fe/La–XM. Fe/La–XM also exhibited an ion-exchange effect during F<sup>−</sup> adsorption, with CO<sub>3</sub><sup>2−</sup> emerging as the primary competing anion. Even after four adsorption–desorption cycles, Fe/La–XM retained &gt;62 % and &gt;65 % of its removal efficiency for As and F, respectively. Tests on actual groundwater samples yielded exceptional results,The equilibrium concentration of As was lower than the agricultural irrigation water standard (C<sub>As</sub> ≤ 0.05 mg/L) and that of F was lower than the drinking water standard (C<sub>F</sub> ≤ 1.0 mg/L) after adding only 0.06 g of Fe/La–XM in the groundwater sample. demonstrating the material's potential for practical applications.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"348 ","pages":"Article 131606"},"PeriodicalIF":4.7,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145227170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydroxylation is found to severely degrade mechanical performance compared to oxide-only systems in uniaxial compression tests.

Size effects play an extremely dominant role in thinner nanopillars, where high surface-area-to-volume ratios enhance hydroxylation-induced mechanical softening. Hydroxylated shells have inferior load-carrying ability compared to pure oxide films, as indicated by radial distribution function analysis revealing disordered atomic coordination and reduced Fe–Fe metallic bonding density.

Particular attention is given to the effect of Cr, Ti and Si interlayers on enhancing the service performance of the CrWN–Ru coating system. CrWN–Ru, Cr/CrWN–Ru, Ti/CrWN–Ru, and Si/CrWN–Ru coatings were deposited on quartz glass substrates using plasma-enhanced magnetron sputtering. A comparative experimental approach was adopted to investigate the mechanical and tribological properties of the four coating systems. The results demonstrate that plasma-enhanced magnetron sputtering enables the fabrication of CrWN–Ru coatings with satisfactory surface quality and structural stability on quartz glass substrates. The introduction of Cr, Ti, and Si interlayers was found to reduce the surface quality of the coatings without altering their preferred crystallographic orientation, while the phase structure remained stable. At the same time, the presence of interlayers enhanced the hardness and Young's modulus of the CrWN–Ru coatings, thereby improving their overall strength–toughness balance. Among the systems examined, the coating with a Cr interlayer exhibited the best performance, achieving the highest hardness (9.35 GPa) and Young's modulus (144.55 GPa), together with superior toughness and film–substrate adhesion. In contrast, the CrWN–Ru coating without an interlayer demonstrated excellent tribological behaviour, with the coefficient of friction and wear rate reaching as low as 0.326 and 1.14 × 10<sup>−7</sup> mm<sup>3</sup>/N·m, respectively. However, the introduction of interlayers was observed to diminish the wear resistance of the CrWN–Ru coatings, and this adverse effect became more pronounced with increasing interlayer thickness. All four CrWN–Ru coatings were found to exhibit a similar wear damage mechanism, which proceeds through the sequence: friction - oxidation - adhesion - abrasive wear - crack formation - delamination. This study provides theoretical guidance for the design, optimisation, and performance tailoring of CrWN–Ru coatings on quartz glass substrates, thereby promoting the application of quartz glass in the field of precision glass moulding.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"348 ","pages":"Article 131568"},"PeriodicalIF":4.7,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
