Abstract Lately, the MAX phases have been gained an enormous technological attention due to their duel inherent metallic and ceramic properties. Herein, we have investigated by means of the full potential linearized augmented plane wave (FP-LAPW) method for determining the structural, mechanical, electronic and thermodynamic properties of 312 MAX phases M3SnC2 (M = V, and Nb). The intended M3SnC2 compounds generally exist in two possible polymorphs α and β polymorph structures. Further, the form...

Abstract To study the relationship between the twinning deformation and grain size of a magnesium alloy under combined tension-torsion cyclic (CTTC) loading, CTTC loading experiments with different paths and statistical analysis of the microstructure (grains and twins) were carried out. The test results show that the axial and tangential stress-strain cyclic curves present different symmetrical or asymmetrical characteristics due to the activation of the twinning-detwinning deformation mechanism...

Abstract Potassium diformate (KDF) is a good substitute for antibiotics in animal feed. Based on the response surface methodology for optimizing the preparation conditions of microspheres. the optimal formulation was as follows: the concentration of ALG was 2%, the concentration of CaCl2 was 2%, and 0.4 mL of surfactant. The objective of the present study was to microencapsulate the KDF antibacterial microspheres by emulsification/external gelation. The structure, morphology and thermal properti...

Abstract Manganese oxide nanoparticles (Mn3O4 NPs) are widely used in catalytic reactions due to their electron transfer activity. In the present study, Mn3O4 NPs, graphene oxide (GO) and their nanocomposite (NC) were synthesized by sol-gel, modified Hummer’s and ultra-sonication methods respectively. Their polyphenol oxidase (PPO) mimic activity was comparatively analyzed. The synthesized NPs and NC were characterized by Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD), ...

Abstract The effects of the content and position of SMA wires on the static properties of glass fiber reinforced epoxy (GF/epoxy) composite laminates prepared by vacuum-assisted resin infusion (VARI) process were investigated. According to the influence of different embedding content and position of SMA wire on mechanical performances of composite laminates, the optimal content and optimal position of SMA were found out. The static mechanical finite element models of GF/epoxy composite and shape...

Abstract The effects of strain rates on the plastic deformation behavior and serrated flow of Zr55.7Cu22.4Ni7.2Al14.7 bulk metallic glass (BMG) were studied by compression test at room temperature. The results show that the plastic deformation behavior of metallic glass at room temperature is highly sensitive to strain rates. The plastic strain, yield strength, compressive strength and fracture strength were found to increase with decreasing of strain rates. For example, the plasticity and the c...

Abstract We report the spin reorientation transition and spin switching transition in perovskite structure YbFeO3 single crystal. A spin reorientation transition of type Г4→Г2 occurs in the temperature range of 6 ∼ 8 K, and a type-Ⅱ spin switching along c-axis is found at temperature about 20 K under an applied magnetic field of 100 Oe. In field-cooled-cooling (FCC) process, due to the spin reversal of Yb3+ magnetic moments, the magnetic moments coupling of Yb3+ and Fe3+ change from parallel to ...

Abstract The electronic effects produced by molecular adsorption of some environmentally potent oxides of nitrogen, N2O, NO, and NO2 on chemically modified surfaces of graphene are investigated, employing spin-polarized density functional calculations. Graphene surface is modified chemically with substitutional doping through boron, nitrogen, and co-doping, with combinations of boron and nitrogen. In the case of adsorption of the paramagnetic species, NO and NO2, rather exotic effects on adsorpt...
