Na-GMMT/TPS pellets (TPS for short) were prepared with sodium montmorillonite as filler. TPS was blended with PBAT in different proportions, and TPS-PBAT composites were prepared by twin-screw extruder. The structure and properties of TPS-PBAT composites were characterized by universal material testing machine, X-ray diffraction (XRD), thermogravimetric analyzer (TG) and scanning electron microscope (SEM). The results show that when TPS is used as matrix, the tensile strength of the composites can be greatly improved while maintaining good elongation at break. The elongation at break of TPS-PBAT-4 composites is 233.3% and the tensile strength is 18.9 MPa. With the increase of TPS content, the diffraction peaks of the composites gradually flatten, indicating that the addition of TPS reduces the crystallinity of the composites. The addition of TPS improves the thermal stability of corn starch and PBAT. When PBAT is used as matrix, the compatibility between TPS and PBAT is poor. When TPS is used as matrix, there is no obvious boundary between TPS and PBAT, and it shows better compatibility. [ABSTRACT FROM AUTHOR]

In order to improve the utilization rate of iron tailings and reduce the cost of grouting materials, the method of replacing river sand and fly ash with iron tailings sand and partially replacing cement with activated iron tailings powder was selected for the test. Using orthogonal test method, factors such as water cement ratio, cement sand ratio, tailings powder, and fly ash content were studied. Research showed that the influence of four factors on the strength of grouting materials was ranked in descending order: water cement ratio, tailings powder, fly ash, and cement sand ratio. Through range analysis, the optimal factor level combination for 28 days was determined to be a water cement ratio of 0. 36, a cement sand ratio of 1 ∶ 0. 6, a tailings powder content of 10%, and a fly ash content of 6%. Through contrast tests, the feasibility of completely replacing river sand and fly ash with iron tailings sand and partially replacing cement with activated iron tailings powder was clarified. Through X-ray diffraction (XRD) and scanning electron microscope (SEM) analysis, it was found that under the test conditions, the performance of grouting materials was improved by the production of tricalcium silicate, ettringite and other hydration products during the hydration and hardening process of grouting materials. Incomplete crack and hydration reaction would reduce the strength of grouting material. [ABSTRACT FROM AUTHOR]

Using zinc nitrate hexahydrate and 2-methylimidazole as raw materials and absolute ethanol as solvent, the precursor ZIF-8 was prepared by the mechanical stirring method, and zinc oxide nanorods at different temperatures were prepared by thermal deposition of the precursor, respectively.ZnO-X（X=700,800,900）.The X-ray diffractometer（XRD） patterns showed that the ZnO nanotubes at different temperatures had complete crystallization and high purity.It can be seen from the scanning electron microscope（SEM） that the size distribution of the precursor is 0.5～2 μm; as the thermal deposition temperature increases, the diameter gradually increases from 150 nm to 2 μm, and the length increases from 1 μm to 30 μm.The photocatalytic degradation experiments showed that the degradation efficiencies of ZnO-700,ZnO-800,and ZnO-900 to rhodamine（RhB） were 63.1%,62.1%,and 62.8%,respectively, after 150 min of illumination.The obtained ZnO nanorods have an obvious photocatalytic degradation effect on RhB.

The surface of AM60B magnesium alloy was micro-arc oxidized by adding nano-Al2O3 particles to the electrolyte to prepare Al2O3-MAO composite film, and a single MAO film was prepared without adding nano-MAO particles as control. In 3.5% NaCl solution, the electrochemical experiments of open circuit potential, electrochemical impedance spectroscopy and potentio dynamic polarization curves were carried out at different temperatures. The macroscopic morphology of the sample was observed by optical microscope before and after corrosion. The morphology was observed by scanning electron microscope (SEM) before and after corrosion, and the elements on the surface of oxide film were measured by energy spectrum analyzer (EDS) before corrosion. Finally, the composition of the oxide film was measured by X-ray diffractometer (XRD) before and after corrosion. Results show that the Al2O3-MAO composite film is more uniform and the surface micropores are smaller than the MAO film. At the same temperature, the corrosion resistance of Al2O3-MAO composite film is better than that of MAO film, and the corrosion resistance of Al2O3-MAO composite film decreases with the increase of temperature.

In order to evaluate the effects of copper nanoparticles on the chemical structure, thermal properties, crystal structure and mechanical tensile properties of polyamide fibers, both the polyamide fibers containing 0.5% nano-copper and the ordinary polyamide fibers were characterized by scanning electron microscope, Fourier transform infrared spectrometer, X-ray diffraction, thermogravimetric analyzer and differential scanning calorimeter. And the relationship between structure and mechanical tensile properties was also explored. The results show that copper nanoparticles embedded in polyamide matrix did not affect the chemical structure of the fibers. The decomposition of a few small molecules in polyamide fiber can be accelerated by nano-copper. Compared with ordinary polyamide fibers, the primary decomposition of antibacterial polyamide fiber start at a higher temperature, and the residual carbon content is lower. The antibacterial polyamide fiber has higher melting point, crystallization temperature and crystallinity, smaller crystal size, larger crystal surface spacing, higher tensile strength and breaking elongation, while the initial modulus is lower, and the variable coefficients of mechanical properties are larger.

BACKGROUND: The successfully prepared zirconia-based nano-hydroxyapatite functional gradient bioceramics has mechanical properties of strong interlayer bonding, high compressive and shear strength, but its biological properties are yet to be studied. OBJECTIVE: To detect the micro-morphology and phase of the zirconia-based nano-hydroxyapatite functional gradient bioceramics using scanning electron microscope and X-ray diffractometer. METHODS: Cylindrical zirconia-based nano-hydroxyapatite functional gradient bioceramics were longitudinally sectioned into thin-shaped specimens with turbine handpieces. The profile (intersections of layers) was polished with sandpaper. Its surface micro-morphology and layered structure were observed with a scanning electron microscope after spraying gold. The test piece was ground into a powder in an agate mortar and filtered with gauze. Ceramic powder was sieved with smaller particle size for phase analysis with X-ray diffractometer. RESULTS AND CONCLUSION: (1) Scanning electron microscopy showed that the gradient layers were tightly bound. The grain volume was basically uniform. There was a small amount of ZrO2 agglomeration. The closer to the surface layer, the higher the nHA content and the uniform small pores. (2) The X-ray diffractometer detected mainly the tetragonal phase ZrO2 and nHA diffraction peaks, and a small amount of β-TCP, α-TCP, CaZrO3 and a small amount of monoclinic phase ZrO2 crystal. (3) The research results indirectly indicate that the surface layer nHA is firmly bonded to the ZrO2 matrix layer under the transition of the gradient layer. ZrO2 based nHA functional gradient biomaterial is a ceramic material with excellent mechanical and biological properties. [ABSTRACT FROM AUTHOR]

The corrosion behavior of low-C medium-Mn steel in a simulated marine environment was investigated by drying-wetting cycles test. Scanning electron microscope (SEM) was used to characterize corrosion morphology. Electron probe micro-analyzer (EPMA) was utilized to observe the cross-section morphology and analyzed the distribution of Mn. X-ray diffraction (XRD) was employed to study the phase analysis of corrosion rust. The results showed that corrosion rate rises quickly at the beginning then decreases subsequently and finally tends to be stable. Corrosion products are gradually transformed into a dense and thick corrosion rust from the loose and porous morphology with the extension of the corrosion time. The main corrosion product in the high chloride ion environment is γ-FeOOH. In the meanwhile， there are many manganese oxides and iron-manganese oxides in the corrosion rust which were not found in other steels. Those corrosion phases can promote electrochemical reaction and accelerate the corrosion process. [ABSTRACT FROM AUTHOR]
