Foam copper (CF) and thioacetamide (TAA) were used as copper source and sulfur source respectively, ethanolamine (en) was used as complexant, and ethanol was used as solvent. Under solvothermal conditions, the [Cu(en) 2]^ 2+ metal complex formed by Cu^2+ and ethanolamine reacted with S^2- in solution to obtain an unstable inorganic-organic Cu 2S-TAA precursor, which was used as a molecular template to control the growth of crystals. Finally, Cu 2S tetradecahedron grown on the copper foam was prep...

Effect of Pyrolysis at Medium and Low Temperature on Desulfurization of Lignite and Content of Sulfu

Decreasing the content of sulfur in semi-coke applied in the civil fuel is of great significance to reduce the emission of pollutants from the combustion of coal-based fuel. The low-sulfur semi-coke as civil fuel was prepared from Inner Mongolia Xilin Gol lignite with the method of pyrolysis. The influences of different temperature, heating rate, holding time and particle size on total sulfur, organic sulfur and inorganic sulfur in semi-coke were investigated in order to obtain the optimum condit...

The Study on the Formability of Fe-30Mn-9Al-1C Lightweight Steel

The strain-hardening index ( n -value) and Lankford value ( r -value) of Fe-30Mn-9Al-1C steel were determined by uniaxial tensile test. Comparing these two values with the test values of three other automotive steels, it was found that Fe-30Mn-9Al-1C steel has good uniaxial deformation capability. However, the results of Erichsen cupping test showed that Fe-30Mn-9Al-1C steel has insufficient crack resistance under biaxial deformation. The reason was that the hard, intergranular κ-carbide particl...

The Molecular Dynamics Study on Surface Modification of Austenitic Stainless Steel by High Ions Puls

The surface of austenitic stainless steel irradiated by energetic beams was studied by molecular dynamics (MD). Thermal spike model was used to simulate the energy transferring process under irradiation. By analyzing the energy distribution and the atomic motion, the mechanism of energy consumption was determined. One part of energy was consumed by the atoms on the surface through evaporation and heat conduction. The other part transferred deep inside the matrix in shock wave form. The smooth pro...

Comparison of Fracturing Features and Permeability Enhancement of Coal Fractured by Water and Superc

Based on the academic thought of non-aqueous fracturing, the coal cylindrical samples with different crack morphology were obtained by water and Sc-CO2 fracturing. The permeability of coal after fracturing was measured under in-situ conditions, thus the fracturing characteristics and anti-seepage effect of water and Sc-CO2 cracked coal is analyzed. The results show that, compared with hydraulic fracturing, under the same stress condition, Sc-CO2 fracturing has a lower initiation pressure, the cur...

Research on Improved Ant Colony Algorithm in Mobile Robot Path Planning

Ant colony algorithm (ACO) is a mellow method for planning route for robots, but it has some weak points like slow convergence and poor path optimization ability. The new algorithm proposed a modified method in this paper to overcome these shortcomings. This method has two steps. It uses bird swarm algorithm (BSA) to build the pheromones distribution and then uses ACO to search route. It was found that this method could build a shorter path effectively under the same condition. The algorithm comb...
