J. Cent. South Univ. Technol. (2009) 16: 0166-0171 DOI: 10.1007/s11771-009-0028-0 Formation mechanism of aerodynamic drag of high-speed train and some reduction measures TIAN Hong-qi(田红旗)1, 2...; Abstract: Aerodynamic drag is proportional to the square of speed. With the increase of the speed of train, aerodynamic drag plays an important role for high-speed train. Thus, the reduction......
Magneli phase titanium sub-oxide conductive ceramic TinO2n-1 as support for electrocatalyst toward oxygen reduction reaction with high activity and stabilityWU Qiu-mei(伍秋美)1, RUAN Jian-ming(阮建明)1..., and Pt/TinO2n-1 composites were prepared by the impregnation-reduction method. The electrochemical stability of TinO2n-1 was investigated and the results show almost no change in the redox region......
