The proposed geomaterial was prepared by blending EPS beads of different densities and fly ash contents with cement as a binding agent. The effects of three different EPS bead densities (25, 30 and 35 kg/m<sup>3</sup>), four EPS mix ratios (0.5–2.0%) and two cement contents (15 and 20%) on density, compressive strength at three different curing periods, 7, 28 and 90 days; and elasticity modulus were studied. It was concluded that the behavior of FAGM prepared with low-density and low-content EPS is analogous to that of FAGM prepared with high-density and high-content EPS. To evaluate the performance of FAGM as a lightweight and strong material, an empirical ratio of strength to density is defined. FAGM with low-density and high-content EPS can be used as an efficient lightweight filling material, whereas FAGM with high-density and low-content EPS can be used as a strong filling material. Moreover, the geomaterial, which is mainly formed from a freely available industrial byproduct, can be strongly used as a replacement for EPS geofoam blocks.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":"12 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138528435","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}

Within the model, six main groups (including a total of 31 properties) are defined: economic aspects, design and production properties, mechanical properties, physical properties, chemical properties and biological properties. A risk-based fuzzy decision making framework is proposed for prioritization. First, a risk-management decision matrix is created by employing interval type-2 fuzzy failure modes and effects analysis. Afterward, the properties of cobalt–chromium alloys are analyzed by utilizing interval type-2 fuzzy measurement of alternatives and ranking according to compromise solution. In the last phase, a prediction model is devised with an adaptive network fuzzy inference system to save computational time and effort and to enable the incorporation of new scientific results into the biomaterial evaluation process. The results of the current study demonstrate that compatibility, osseointegration, corrosion resistance, fatigue resistance and time-dependent deformation are the top five properties contributing to potential orthopedic implant failures and risks. Furthermore, the developed model produces very satisfactory results with acceptable deviations. Consequently, this study presents a new and reliable guide for the unbiased evaluation of cobalt–chromium alloys.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":"72 1 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138528404","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 aim of this work is to fabricate graphene-reinforced poly(lactic acid) (PLA/Gr) scaffolds with different pore shapes (circular, square and hexagonal) and different pore sizes (1000, 1500 and 2000 μm) using the fused deposition modeling process. The characteristics of the three-dimensionally (3D) printed PLA/Gr scaffolds were analyzed through Fourier transform infrared spectroscopy, thermogravimetric analysis, derivative thermogravimetry, scanning electron microscopy and energy-dispersive X-ray spectroscopy. The water contact angle measurement showed a hydrophilic surface (70 ± 2.7°) for scaffolds with a pore size of 1000 μm. Mechanical property studies showed that the scaffold with circular 1000 μm pores had a compressive strength of 18.53 ± 0.90 MPa, which was similar to the cancellous bone value. In addition, this study involved an examination of the in vitro bioactivity, water uptake and biodegradation characteristics of the scaffolds. The results reveal that the 3D-printed PLA/Gr scaffold featuring a circular pore shape with a pore size of 1000 μm exhibits great potential as an implant for BTE.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":"29 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138528403","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 structural analysis revealed the presence of a cubic CdS lattice with a hexagonal FeS phase in Cd1-xFexS nanoparticles. XRD results showed that the FeCl3 dosages had a significant influence on the formation of ternary Cd1-xFexS nanoparticles. The morphological analysis indicates that the Cd1-xFexS nanoparticles have a spherical shape with a size of approximately 20 nm, while CdS nanoparticles have a size of approximately 12 nm. The optical characterization revealed that the bandgap of pristine CdS and Cd1-xFexS nanoparticles decreased with an increase in Fe content. The bandgap of Cd0.8Fe0.2S was slightly higher than that of CdS, while the bandgap of Cd0.6Fe0.4S and Cd0.4Fe0.6S nanoparticles were lower than that of CdS. The energy band structures of pristine CdS and Cd1-xFexS nanoparticles were calculated using density functional theory and were compared with experimental results. In summary, this work presents a detailed investigation of the structural and optical properties of Cd1-xFexS nanoparticles synthesized using a cost-effective chemical technique. The results demonstrate the potential application of these nanoparticles in various fields such as optoelectronics, energy harvesting, and catalysis.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44179425","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-cast ZMG610 alloy was mainly comprised of α-Mg matrix, Mg7Zn3 phase and Mg3Zn6Gd (I-phase), large number of I-phase particles remained in the matrix after homogenization treatment at 330 °C up to 24 h. As-extruded ZMG610 alloy exhibited a bimodal structure consisting of fine dynamically recrystallized grains with wide orientation spread and coarse un-dynamically recrystallized grains with strong basal texture. All as-extruded samples exhibited typical basal texture with basal plane of most grains paralleled to extrusion direction (ED). The lower texture intensity could be obtained through the increase of both extrusion ratio and temperature. Optimal mechanical properties (YS of 267 MPa, UTS of 360 MPa and EL of 14.2%) were obtained through the combination of low temperature (350 °C) and high extrusion ratio (45). Amelioration of mechanical properties highly depended on the synergistic effect of dynamically recrystallized grains, I-phase particles and texture.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44992769","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}
