However, the synthesis of high-quality BaTiS3 crystals, particularly those featuring crystal sizes of millimeters or larger, remains a challenge. Here, we investigate the growth of BaTiS3 crystals utilizing a molten salt flux of either potassium iodide, or a mixture of barium chloride and barium iodide. The crystals obtained through this method exhibit a substantial increase in volume compared to those synthesized via the chemical vapor transport method, while preserving their intrinsic optical and electronic properties. Our flux growth method provides a promising route toward the production of high-quality, large-scale single crystals of BaTiS3, which will greatly facilitate advanced characterizations of BaTiS3 and its practical applications that require large crystal dimensions. Additionally, our approach offers an alternative synthetic route for other emerging complex chalcogenides.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"59 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141507186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tensile, compression, flexural, and differential scanning calorimetry tests were carried out on 3D-printed CPC, CRPC, and Functionally Graded Multilayered Material (FGMLM) composite structures. The results indicated that FGMLM laminates exhibited increases of 12.4%, 6.4%, and 9.8% in tensile, flexural, and compressive strength, respectively, compared with CRPC laminates; these experimental values were validated by finite element analysis. Further, fractography analysis of the FGMLM was carried out using scanning electron microscopy to provide insights into the structural characteristics.

Multilayered structures are considered an alternative to traditional monolithic shielding materials. This paper investigates such multilayered conductors of cobalt–nickel–iron alloy (CoNiFe) and copper (Cu) to illustrate their superiority over conventional monolithic shields. Modeling, simulations, and measurements demonstrate improved shielding when multilayered stacks are used against magnetic field sources. Furthermore, the stack-ups have excellent shielding even with a thickness of 5 µm. At least 40 dB of additional shielding effectiveness is achieved across 30–1000 MHz as compared to single-layer shielding from monolithic Cu of the same thickness. These innovative stack-ups also exhibit superior shielding when compared to multilayered stacks and shielding materials in literature. Additionally, these stack-ups are fabricated using standard substrate processes such as electroplating. Consequently, this approach becomes commercially viable and applicable to future electronic systems.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"10 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, four ML regression models were utilized to identify high-entropy alloys (HEAs) with high hardness within the Fe–Co–Ni–Cr system. The Bayesian optimized deep learning (BO-DL) method yielded the highest prediction accuracy (R2 = 0.93). Notably, the BO-DL method is no longer limited to a single HEA system and now can target different alloy systems composed of more elements with reliable prediction results. Furthermore, a genetic algorithm was utilized to search for HEAs with high hardness. The accuracy and reliability of the predictions were experimentally verified. As-cast Fe5Co20Ni10Cr30Al5Ti30 HEA exhibited a remarkable hardness of 890 HV, which is one of the highest for alloys in the Fe–Co–Ni–Cr system.

In this study, the use of TPO NP as a photoinitiator for bioprinting gelatin methacrylate (GelMA) was compared with commonly used lithium phenyl-2,4,6-trimethylbenzoylphosphinate (LAP) photoinitiator by assessing the physico-chemical properties, mechanical strength, gelation kinetics, resistance to flow, absorptivity in different solvents, and biological responses. The results demonstrated that the physico-chemical and mechanical properties of the GelMA were similar using LAP and TPO nanoparticles (NP) for crosslinking. The significant cytotoxicity observed in cells exposed to the GelMA with TPO NP suggests that cell-embedded bioprinting may not be feasible and that removal of toxicant may be needed to utilize GelMA scaffolds crosslinked with TPO NP for biological applications.
