The connection tubes are characterized by packing geometries, bond length, intrinsic energy, energy gap, chemical potential, Mulliken populations, charge density differences, and molecular orbitals at HOMO and LUMO energy levels. These simulation results present significant differences compared to straight carbon nanotubes. Charge density differences suggest the bonding changes among the carbon atoms of the tubes having different diameters. The charge amount gained or lost can occur among the atoms at the junction in the small diameter tubes, while the gained or lost charge mainly occurs on the eight carbon atoms in the \"heart\" octagon in the large diameter ones. There are significant differences in HOMOs and LUMOs in the tubes with small chiral indexes. The HOMOs of the tubes with large chiral index are different from the LUMOs at the junction.

However, the calcium silicate hydrate (C–S–H), as the most significant binding phase in cement, has apparent anisotropy characteristics. The enhancement of GO on the tensile performance of C–S–H in different directions requires to be revealed. Hence, in this work, the molecular dynamic simulation was applied to study the influence of GO in different directions on the tensile properties of C–S–H composites and the corresponding reinforcing mechanisms. The results demonstrate that the GO nanosheets incorporated in parallel water layers can reinforce the ductility of C–S–H, with the tensile strain energy density increasing up to about 43.9%. The structural characteristics demonstrate that the GO nanosheets incorporated in parallel water layers significantly change the C–S–H failure mode, whose initial failure diffuses from the GO surface. By contrast, the failure mode of plain C–S–H composites is diffused from the high-stress zone. Nevertheless, when GO nanosheets are incorporated in the vertical water layer direction, the destruction form of the C–S–H composite changes little, with the tensile strain energy density only increasing by 11.9%. The energy evolution characteristics verify that the external work of GO nanosheets added in the parallel water layer is increased by about 53.4%, about 2.4 times higher than that of GO nanosheets added in the vertical water layer. The findings of the study not only promote boarder understanding of GO-reinforced cementitious composite but also assist nanomodification cement design in the future.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"59 46","pages":"21362 - 21376"},"PeriodicalIF":3.5,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142754255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TPEs offers several advantages such as easy processability and requirement of lesser additives, but their additive manufacturing using fused deposition modelling is challenging due to filament buckling and poor layer coalescence. Thus, this work presents the additive manufacturing of smart MREs consisting of spherical carbonyl iron powder (CIP) particles incorporated in styrene-ethylene-butylene-styrene (SEBS) block copolymer matrix using solvent-cast 4D (SC-4D) printing. The effect of varying filler amount on the physicomechanical and electrical characteristics of additively manufactured samples was investigated. Shore hardness and density of the MRE samples increased consistently with an increase in CIP content. However, density deviated significantly from the theoretical density beyond critical filler content (&gt; 60 wt%). Tensile strength improved with CIP content up to 30 wt% and reduced on further increase in filler content. Elastic modulus predicted from six different theoretical models was compared with experimental results. The predictions deviated significantly from the experimental observations at higher filler contents due to complex particle–particle and particle–matrix interactions. Shrinkage and morphology analysis revealed that an increase in CIP content decreased the shrinkage and improved the shape stability of the samples. Electrical conductivity of the MRE samples was found to be close to neat SEBS sample below percolation threshold (~ 50 wt%). Beyond percolation threshold, electrical conductivity increased dramatically. Finally, the actuation capability of the flexible grippers was demonstrated in the presence of an external magnetic field.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"59 46","pages":"21556 - 21580"},"PeriodicalIF":3.5,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142754013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multi-principal components alloy with excellent mechanical properties, good oxidation and corrosion resistance are expected to be applied in molten chloride salts at high temperature. To investigate the corrosion behavior of the dual-phase Fe₃₆Ni₃₆Al₁₇Cr₁₀Mo₁ alloy at different time (48, 96, 144, 192 and 240 h), immersion test was conducted at 700 ℃ in a ternary LiCl–KCl–CsCl molten salt. By analyzing the optical microscope (OM), scanning electron microscopy (SEM) and X-ray diffraction (XRD) results and the standard Gibbs free energy, three corrosion stages (oxidation–dissolution–corrosion) over time were drawn. Active elements such as Al and Cr oxidized first and then experienced dissolution in the acidic environment. After the oxides were depleted, the bare metal started to corrode, and many defects formed on the surface of the alloy, causing severe corrosion. However, for the low corrosion ability of LiCl–KCl–CsCl molten salts, the alloy exhibited excellent performance with corrosion rate of 274.9 μm/y and corrosion depth of 5.52 μm after 240 h, and there was no obvious preferential corrosion of the B2 phase.

The total elongation and fracture toughness increased from 8.3% and 29 MPa /m^1/2 to 13.3% and 45 MPa/m^1/2, whereas the ultimate tensile strength remained at approximately 2.3GPa with increasing partition time, which originated from the continuous transformation-induced plasticity (TRIP) effect and the local domain with high-density high-angle grain boundaries (HAGBs) during deformation-induced martensite transformation (DIMT). On the basis of detailed microstructural characterization, it was found that the formation of HAGB after deformation only evolves from unique martensite variant pairing selection with variant1(V1)/V2 (60°/[111]), which are promoted by plastic accommodation (<span>(sigma_{Y} /sigma_{{gamma to alpha^{prime}}})</span> &lt; 1) and suitable phase transformation driving force (<span>(Delta G_{mech})</span>) by strain-induced martensite transformation (SIMT) with factors including dislocation density, carbon content and grain size (less than 4 μm).
