In this context, based on the idea of turning waste into treasure, we designed a composite material by integrating RM with graphitic carbon nitride (GCN) through a one-step thermal polymerization method for achieving photocatalytic hydrogen (H₂) production. Experimental results indicate that, when the mass ratio of doping in the composite material is 0.8%, the RM/GCN catalyst achieved a hydrogen production rate of 2289 μmol/g under full-spectrum light irradiation, which is significantly higher than the yields obtained from pure GCN or RM alone. In addition, Kelvin probe force microscopy (KPFM) surface potential analysis reveals the S-scheme charge transfer mechanism within the composite material, which not only enhances the light absorption properties, but also effectively suppresses the recombination of photo-generated charge carriers, thus improving the photocatalytic H₂ generation efficiency. This study provides a new design idea for the design of highly efficient photocatalytic hydrogen production materials, and paves the way for the recycling and resource utilization of RM waste.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"10 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677367","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}

However, the inherent lattice instability distinctly hinders their applications in various extreme environments. Herein, we designed a novel liquid-repellent and thermal insulation composite film by the combination of polydimethylsiloxane (PDMS) and hollow glass bubbles (HGB) with CsPbBr₃ QDs. Due to HGB effectively suppressing the thermal stress-induced lattice distortion, the HGB/PDMS-CsPbBr₃ composite film performed highly great optical property in a high-temperature environment. The water contact angle (WCA) measured on the prepared HGB/PDMS-CsPbBr₃ composite film increased from 62.4±6.5° to 149.5±3.1°. Upon being subjected to sodium hydroxide solution (NaOHaq), the HGB/PDMS-CsPbBr₃ composite film could retain its luminescent property for an impressive duration of 30-day immersion. In addition, the HGB/PDMS-CsPbBr₃ composite film exhibited a higher photoluminescence quantum yield (PLQY) of 84.9% and the lower lasing threshold of 0.03 mJ/cm², indicating a potential of optical gain medium for this composite film.

An effective approach for the preparation of gradient titanium alloys involves combining additive manufacturing with forging, where metallic powders are deposited directly onto a forged plate. However, achieving a good strength-ductility combination while eliminating anisotropy in laser deposited titanium alloys remains a significant challenge. To mitigate the performance mismatch at the interface between dissimilar alloys in gradient components, premixed powders of near-α titanium alloy and Ti₂AlNb alloy at different proportions were deposited as a transition layer on the forged titanium alloy substrate by laser deposition in the present work. The microstructure and tensile behavior of the as-deposited mixed titanium alloy powders samples along the horizontal (scanning) and vertical (building) directions were systematically investigated. The results showed that abundant and continuous network substructures characterized by densely and parallelly arranged α₂ phase clusters were formed within equiaxed β/B2 grains of the laser deposited mixed titanium alloy powders containing 50<!-- --> <!-- -->wt.% near-α titanium alloy and 50<!-- --> <!-- -->wt.% Ti₂AlNb, which are conducive to achieving a favorable combination of strength (1007.63<!-- --> <!-- -->MPa) and ductility (8.19%), as well as the elimination of anisotropy. The strengthening contribution of the as-deposited sample with network substructures was primarily attributed to grain refinement and dislocation strengthening, rather than solid solution strengthening. Additionally, the achievement of isotropic strength and ductility was ascribed to the special network substructures with a similar volume fraction and distribution at both vertical and horizontal directions, which reduce the distribution difference in Schmid factor and promote more uniform deformation behavior.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"13 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677270","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}

The crack initiation and propagation process of SCC of the alloy in environments affected by hydrogen was dominantly controlled by HFAD and HEDE mechanisms, respectively. In the crack initiation process of SCC, hydrogen was preferentially accumulated around AlCuMnFe IMPs with low content of Cu to form the hydrogen-affected zone with the Volta potential lower than that of the matrix, resulting in the accelerated pitting initiation and crack initiation. In the crack propagation process of SCC, the aggregation of hydrogen at grain boundaries reduced atomic binding energies, leading to rapid crack propagation along the grain boundaries.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"14 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677298","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}

The results reveal that the moderate Ti atoms (<em>x</em>≤0.15 in CoCrNiTi_<em>x</em>) remain entirely dissolved into the FCC solid solution.
