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. The methodologies and framework proposed in this study can serve as a blueprint for facilitating the design of HEAs.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"12 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512262","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, 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. The results of this study provide a framework for future studies that will consider the microstructure and in vitro properties of GelMA.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"135 11 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512266","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}

As a result of the hetero-atom doping effect and varied structure phase of MoS2, we demonstrated excellent piezocatalysis for the degradation of methylene blue (MB) dye under stirring/ultrasonic catalyzed by MoS2. Compared with pristine MoS2 and O-doping MoS2 (O-MoS2), O-MoS2& reduced graphene oxide (O-MoS2&rGO) exhibits enhanced piezocatalytic activity. When the initial concentration of MB solution is ≤ 15 mg L−1, both stirring and ultrasonication can make the optimal O-MoS2&rGO composite to degrade the dye completely within 20 min.

To improve the TENG, the TPU NFs were decorated with multi-walled carbon nanotubes (MWCNT) functionalized with fluoride, amide, and carboxylic groups. The NF demonstrated a stronger interaction with the carboxylic-functionalized MWCNT (c-MWCNT). Furthermore, the c-MWCNT functionalized TPU/PVDF TENGs were evaluated by applying compressive force (30 psi) utilizing a pneumatic cylinder. The maximum alternating voltage, and current outputs were 158 V and 170 µA respectively. The TENG charging capacity for the samples dipped for 12 h in the c-MWCNT showed an ability to charge a 1 µF capacitor up to 3.03 V in 25 s of hand tapping, suggesting that the fabricated TENG has the capability to function as a self-charging flexible energy harvester.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"159 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512265","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}

The results indicate that the average thermal expansion coefficient of the Cu/ Ti3C2TX composite foil decreased by 11.26% compared to that of pure copper. Due to the high electron mobility of Ti3C2TX and the favorable Cu/ Ti3C2TX interface, the electrical conductivity of the Cu/ Ti3C2TX composite foil exceeded that of pure copper by 8.7%, reaching 6.2147 × 107 S·m−1, and its thermal conductivity increased from 381.5 W/m·K to 423.5 W/m·K.

Different AgNO3:NaBH4 molar ratios (1:1–1:6) and PVP concentrations (1–3–5–10%) were investigated. For further studies, AgNO3:NaBH4 molar ratio of 1:3 and a 3% PVP were selected, resulting AgNps with a diameter of 91.54 ± 7.62 nm. Silver release behavior of the scaffolds exhibited a burst release within the first 12 h, followed by a plateau within 2 weeks.
