The present study aims to fabricate 3-aminopropyltrimethoxysilane (3-APTMS) functionalized gold (Au)-silver (Ag) nanoparticles incorporated in hydroxyapatite bioceramics to overcome this limitation. Thermogravimetric analysis (TGA), X-Ray diffraction, and scanning electron microscopy were carried out to understand the physical and chemical characteristics of the material. The maximum values of fracture toughness, hardness, compressive and flexural strength were measured for HA-10 Au/Ag NPs. Both quantitative and qualitative analyses of antibacterial behavior revealed that the adhesion of gram-positive (Staphylococcu aureus) and gram-negative (Eschericia coli) bacterial cells were reduced significantly after the incorporation of Au/Ag NPs as compared with the HA control. In addition, the effect of Au/Ag NPs incorporation on the cellular response was observed for the MG63 cell line. Both the quantitative and qualitative results indicate significantly enhanced cell proliferation with the incorporation of Au/Ag NPs as compared to HA. The addition of Au/Ag NPs in HA provides a material with appropriate mechanical, antibacterial, and cellular responses for further consideration.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"61 4 1","pages":"4157 - 4174"},"PeriodicalIF":0.8,"publicationDate":"2023-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79334310","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}

Microscopically, the voids in the sintered nano-silver exhibit multi-scale distribution under specific sintering conditions, the corresponding failure mechanism is clarified by finite element analysis and scanning electron microscopy. Furthermore, a yield strength model with different porosity was proposed, which was adopted in the finite element analysis to investigate the microstructure evolution of sintered nano-silver. Eventually, the multi-scale simulation of the failure realized through the finite element model, the stress state of microstructure and the failure mechanism that is dependent on the multi-stage void were confirmed by the numerical simulation and experimental analysis.

The authors have explored the effect of laser energy densities on the surface morphology, microstructure and mechanical behaviour of 17-4 precipitation hardened stainless steel fabricated under the direct metal laser melting technique. The considered processing parameters were laser energy density and its technical parameters: laser power, layer thickness, hatch spacing and scanning speed. The mechanical and metallurgical properties of the as-printed samples appeared better than the wrought counterpart due to the higher densification level (99.74 %) induced by the rotating scanning strategy. X‐ray diffraction revealed the presence of both the martensitic α phase and austenitic γ phase in the as-printed sample. There is no significant anisotropy in the mechanical behaviour as the build direction has a random texture with a fine columnar grain structure. The high laser energy density with low layer thickness results in an excellent surface finish. The tensile strength (1180 MPa) and the elongation for the as-printed sample (45.0 %) were considerably more significant than that for the wrought sample (1160 MPa and 26.0 %), which is attributed to the combination of low and high-angle boundaries, as confirmed by the electron backscatter diffraction results.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"114 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78977825","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}

Current approaches for understanding texture evolution in F-BAM are majorly considerate of the phenomena occurring only during solidification. This hinders the comprehensive understanding and control of texture during F-BAM. In this perspective article, we discuss several physical phenomena occurring during and after solidification that can determine texture in F-BAM processed stainless steels (SS). A crystal plasticity-coupled hydrogen adsorption-diffusion modeling framework is also leveraged to demonstrate the prospects of grain boundary engineering with F-BAM for enhanced hydrogen embrittlement resistance of SS. Implications of varying thermokinetics in F-BAM for solidification behavior of SS are discussed. Additionally, microstructural attributes that are key to high temperature mechanical performance of SS are highlighted. Considerations as outlined in this perspective article will enable grain boundary engineering and application specific microstructural design of SS with F-BAM.\u0000 Graphical abstract","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"141 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80103612","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 demonstrated efficient biocompatible loading of CDDP onto a TNA nanosystem using the top-filling method, with an encapsulation efficiency of 98.95 ± 7.02%. This was confirmed by ICP-OES, which detected platinum (Pt) ions for up to ten days.
