Abstract: Stop motion is an animation form full of amusement, in todays animation industry we have profound 2D and 3D works been produced which lead the audience to an motion fatigue on these fictitious experiences, they tend to watch more vivid and authentic stop motion, why audiences are deeply attracted by characters made of various materials And why stop motion can express a strong sense of authenticity This essay will demonstrate the features of materials through the study on the texture and unfold the beauty of this material expression.

Abstract: The structural, electronic and thermodynamics stability properties of the new hydrogen storage materials Mg₁₂Ni_6-xCr_x (x=0, 1) are analyzed based on the density functional theory (DFT). The enthalpy of hydride formation of Mg-Ni alloys is-65.07kJ/mol (H₂). For a small range of Cr doping, the enthalpy of hydride formation of the Mg-Ni-Cr system is-54.99 kJ/mol (H₂), widely accepted as considerable value for applications. The thermodynamics properties of Mg₁₂Ni_6-xCr_x H₂(x=0, 1) are expected to be improved by addition of Cr elements. The results will play an important role in practical research field.

Abstract: The material constants calculation models for hyperbolic-sine creep model were proposed. The material constants used in hyperbolic-sine creep model for 316 stainless steel were calculated due to the models proposed and experimental data in the temperature range from 873K to 1023K. The relationships between material constants of 316 stainless steel creep model and temperature were obtained by curve fitting. The creep rate predict model of 316 stainless steel with only stress and temperature was also developed, the creep rates predicted were in good agreement with experimental data.

Abstract: In this paper, LiFe_0.95Mn_0.05PO₄/C was prepared by using simulated FeCl₃ etching waste as iron source for lithium-ion battery cathode materials. The structural and morphological properties of the samples were characterized by X-ray powder diffraction (XRD) and Scanning electron microscopy (SEM). The electrochemical performances of the sample were also investigated with charge and discharge test. The achieved results indicate that product obtained was confirmed to be LiFe_0.95Mn_0.05PO₄ and has the advantage of high purity, small size and good electrochemical performance.

Abstract: A novel anticaking material was prepared from from Bentonite, Biological Carbon and abandoned animal/plant oil in this study. In order to determine the optimal dosage of bentonite, biological carbon and abandoned animal/plant oil, the experiments has been performed systematically. The effect of anticaking materials was described by caking ratio. BAC was prepared by 30g of bentonite, 5g of abandoned animal/plant oil, 2.0g of biological carbon. With dosage of BAC is 10g / 200g (compound fertilizer), In the 30 days storage period, preparation of BAC can achieve the requirement of the anti-caking. However, the anti-caking effect is weaker as the longer storage time and Anti-caking cycle of BAC is shorter.

Abstract: Fe-N co-doped NaTaO₃ was prepared by hydrothermal method with different Fe-N concentrations (Fe-N molar ratio 1:1) and characterized by the XRD, SME and UV-vis diffuse reflectance spectra. The results showed that Fe-N co-doped samples were given an increase surface and narrow band gap (2.92 eV) compared to pure NaTaO₃. The sample doped with 0.15% Fe-N of a molar ratio displays highest photocatalytic activity in the degradation of methyl orange under visible light irradiation.

Abstract: Copper-plated short carbon fiber/copper-plated Ti₃SiC₂-Cu-graphite composite, copper-plated short carbon fiber/Ti₃SiC₂-Cu-graphite composite with the same carbon fiber content and copper-plated Ti₃SiC₂-Cu-graphite composite were prepared by the powder metallurgy method. Physical and mechanical properties of these composites were tested. The dry friction tests of the composites under sliding velocity of 10m/s and load of 4.9N were conducted for 36 hours. The results show that the properties of the Cf-copper-plated Ti₃SiC₂-Cu-graphite composite such as electric conductivity, bending strength and wear resistance are remarkably increased than those of either Cf-Ti₃SiC₂-Cu-graphite or copper-plated Ti₃SiC₂-Cu-graphite composites.

Abstract: Abstract. Electrodeposition of ZnS thin film is affected by many factors. The effects of experimental conditions and concentrations of complexing agents on the electrochemical properties of plating solution were investigated. Electrochemical workstation was used to test cyclic voltammetry curves in different situations. According to the oxidation and reduction peaks of the curves, the experimental results showed that the effect of complexing agent was the best, while the ammonia was worst. With the increase of concentration of sodium citrate, reduction peak shifted to the negative part, in the meanwhile plating solution with 30 mmol/L of sodium citrate was the best condition for electrodeposition of ZnS thin film.

Abstract: Due to its good wear resistance, Al-20Si is widely used as piston. But coarse primary silicon greatly undermines the mechanical properties of Al-Si alloy. The primary silicon could be refined in pulse magnetic field with suitable magnetic flux density and magnetic field frequency. In this work, the microstructure of Al-20Si alloy with and without pulse magnetic field treatments was observed, and the influence mechanism of weak pulse magnetic on the microstructure of the alloy was investigated. The results showed that the grain size of primary silicon fluctuated with increasing magnetic flux density at 1Hz. The smallest grain size of primary silicon is obtained at 94mT. The grain size of the primary silicon decreased with increasing magnetic field frequency under the magnetic flux density of 94mT.

Abstract: Three novel B, N, S-containing tri (hydroxymethyl) propane (TMP) esters were synthesized. The anti-wear performance of the synthesized compounds as additives in rapeseed oil (RO) was evaluated with a four-ball tester. The results show that the novel TMP esters have good antiwear performance when they are used as additives in rapeseed oil under all test loads. The action mechanism was investigated through analysis of the X-ray photoelectron energy spectrometer. The results indicate that the additives in RO adsorb and react with metal surface to form a protective film composed of organic compounds, B₂O₃ and iron oxide.
