Activated carbon for supercapacitor was prepared from Inner Mongolia lignite by microwave heating with KOH as activation agent.The pore structures of activated carbon was characterized by N2 adsorption at 77K,the electrochemical performances of activated carbon electrode materials were evaluated by constant current ch…
The effect of cooling rate on the solidification microstructure and corrosion resistance of high chromium white cast iron (Cr28)was investigated. The results indicate that the corrosion rate of high chromium cast iron largely depends on Cr concentrations in the matrix and the volume fraction of carbides. The rapid coo…
The efficient amine carboxylated functional modification of macroporous adsorption resin D101 was obtained through chloromethylation and functionalization on commercially available D101.The structure of D101 and its modified product were characterized by FT-IR and BET.The preliminary investigation and optimization of…
The structural and fluorescent memory effects of Mg-Al-Eu ternary layered hydroxides(TLHs) through the calcined TLHs were studied by immersing in CO2-free deionized water(pH = 7),phenylalanine solution(pH =5),and different sodium phenylalanine solution(pH = 8,9 and 11),respectively.X-ray diffraction(XRD) results showe…
Aiming at the problems of incomplete filling and demoulding caused the helix angle for aviation helical gear in the forming process of the helical gear forging,the floating concave die structure for helical gear forging die was designed.The bearing die structure was reasonably designed to make forgings demoulding smoo…
Technology of Ni-P-SiC direct electroless composite coating on the surface of ZL102 was investigated. The effects of main bath ingredients, technical conditions and the micro particles SiC addition content on the deposition rate and the porosity were discussed, and the hardness, corrosion resistance, bonding strength…
The formulation design idea and construction technology of a waterborne metallic coatings used for aluminium profile were introduced,and the influence of the aluminium arrangement of the waterborne metallic coatings and the influence on the electrostatic spraying technology were discussed.
Spherical cathode materials xLi2MnO3 ·(1-x) Li(Ni1/3Co1/3Mn1/3)O2(x =0.2,0.4 and 0.6),using ammonia as complexing agent,were synthesized by hydroxide co-precipitation method.Chemical component,structure,morphology and electrochemical performance of synthesized materials with diverse components were characterized by ED…
The current research status of catalyst used for catalytic desulfurization of flue gas was introduced in this paper,and the performance of metal supported catalyst was specifically researched.With active carbon as the carrier,metal nitrate as pickling liquid,8 kinds of metal supported catalyst was prepared through equ…
The nano-SiO2 material after the surface treatment was mixed with PP,POE,and thus nano SiO2 / POE / PP composite was prepared. The tensile yield strength,impact strength,shrinkage and the cycle of molding were studied, and the formulation of well synthetically properties was obtained by orthogonal design. The results…
On the basis of measuring the pig gelatin protein content and amino acid composition,the different protease used to hydrolyze.DPPH.radical scavenging rate is a filtering factor.Next,we used enzyme to hydrolyze pigskin gelatin.The hydrolysis conditions were optimized by response surface methodology on the basis of sing…
The existing wet-process phosphoric acid purified technology was systematically summarized.The industrialized solvent extraction and chemical precipitation combination process flow were discussed.By introduction to the domestic large enterprises wet-process phosphoric acid purified project progress,in response to the…
The author studied the application of involute as a basic type line,designed a new type of involute surface wedge backstop with the application of Pro/E software for design and analysis,verified the design parameters.The author analyses the stress of the traditional cylindrical surface wedge backstop and involute surf…
Taking Q235 low-carbon steel and 316L austenitic stainless steel as mother material,and the steel was welded by manual arc welding.Taking A042 as overlay and A022 as packing material,the Q235/316L was welded.After welding,the different steel welded joint is aging treated at 300 ℃,500 ℃,700 ℃ for 2 h.Then the mechanica…
In order to replace the poisonous hexavalent chromium in the passivation treatment technology of copper foil,a new passivation treatment technology is studied by using sodium molybdate and phytic acid as additives.The passivation treatment experiment was conducted directly to the copper foil that had been treated by c…
The electronic structure and magnetic properties of Mo-doped blende DMS B1-x Mox N(x= 0.062 5,0.125)were investigated by the first-principles plane wave pseudopotential method with the generalized gradient approximation.It is shown that Mo-doped blende BN has clear half-metallic characteristics,Mo atoms in a dilute co…
According to the electromagnetic characteristic of chiral metamaterials(CMMs),wave in CMMs is splitted into a left and a right-handed circularly polarized waves based on Bohren's wave decomposition scheme.By applying the continuous boundary condition on the interfaces of the sphere,the electromagnetic scattering of CM…
