atmosphere and then CNTs were modified by Triton x-100 (CNTs-T). Ni-B amorphous alloy catalysts supported on CNTs and CNTs-T were prepared by impregnation-chemical reduction method. The catalysts were... on CNTs was conducted according to previous work (The final product is labeled as CNTs-T)[13]. Ni-B/CNTs, Ni-B/CNTs-T amorphous alloy catalysts were prepared by impregnation-chemical reduction method......
. Therefore, the new proposed shape products give a mass reduction of 4.8 kg(5.1%) Key words: CNG fuel storage vessel; mechanical property; dome part; bursting; structural analysis 1 Introduction... kg and 89.9 kg, respectively, giving a mass reduction of about 4.8 kg (5.1%). Acknowledgement This work was supported for two years by Pusan National University Research Grant......
investigated during thermal processing. The samples of 4 mm in thickness machined from cast ingot were compressed at 300 ℃ with a thickness reduction of 75% and cooled in the water to room temperature... under a thickness reduction of 75% at 300 ℃. The results suggest that warm forming not only can refine grain, also produce the largest amount of deforma- tion through the smallest compression passes......
suppress reduction of solvent and thickening of the solid electrolyte interface (SEI) layer on graphite surface. Electrolyte with VC is considered to be a good candidate for improving cycling...: 5617-5622. [20] ZHANG X, KOSTECKI R, RICHARDSON T J, PUGH J K, ROSS P N. Electrochemical and infrared studies of the reduction of organic carbonates [J]. Journal of the Electrochemical Society......
by the reduction of interfacial energy, will inevitably and continuously occur with the extension of heating and holding. Key words: AZ91D magnesium alloy; deformation; isothermal holding; microstructure... was defined by the relative reduction of the sample height. The eutectic and liquidus temperatures of AZ91D were 439 ℃ and 595 ℃, respectively, by the curve of differential scanning calorimetry(DSC)[5......

And the effect of carbon dioxide emission reduction of high-speed railway is very good. Key words......
at the same reduction. Key words: cryogenic rolling; copper alloy; texture evolution; recrystallization behavior 1 Introduction Recently, there is a great interest in bulk ultrafine grained (UFG) materials... direction was parallel to the axis of the bar. The total reduction of the samples was 90% overall the thickness (diameter) with per pass of ~10% in thickness. During the CT-rolling, the samples were......
micelle via a solution reduction of Pd(NO3)2 by hydrazine hydrate. The size of the particles can be controlled by manipulating the relative rates of the hydrolysis and condensation reactions of titanium... and sol-gel processing at R=4, H=50, and x=1 4 Conclusions Metallic Pd clusters were embedded into a TiO2 nanoparticles that were synthesized within reverse micelle via a solution reduction of Pd(NO3)2......
(ECMP) of copper was investigated. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) analyses were used to observe the surface profile. Finally, the oxidation and reduction... monitored the oxidation and reduction step of the Cu surface by the repetition of anodic and cathodic potential in KNO3 and HNO3 electrolyte.

, which dissevers the matrix and leads to the reduction of the strength and impact-toughness of the alloys. Hence, the mechanical prosperities of ZA105 high zinc magnesium alloy are significantly improved.... However, zinc addition resulted in the increase of brittleness of magnesium alloy and reduction of its impact toughness[10]. In order to solve the above problems, we added Sb in Mg-Zn-Al alloys......
