Natural tea-leaf-derived, ternary-doped 3D porous carbon as a high-performance electrocatalyst for the oxygen reduction reaction Zhaoyan Guo1, Zhen Xiao1, Guangyuan Ren1, Guozheng Xiao1, Ying Zhu1,*, Liming Dai2,*, and Lei Jiang3 1 Beihang University, China 2 Case Western Reserve University, USA 3 Institute of Chemistry, Chinese Academy of Sciences, China 1244–1255

Natural biological materials, such as tea leaves, are used as precursors for the large-scale fabrication of heteroatom ternary-doped hierarchically porous carbon (HDPC-X). The product is formed by pyrolysis of the tea leaves under nitrogen atmosphere at high temperatures. Tea leaves not only act as the templates for construction of 3D hierarchical pores, but also provide the doping of heteroatoms in the carbon framework. As a result, HDPC-Xcatalysts display high catalytic performances, long-term durability,and good methanol/CO tolerance, making HDPC-X a promising alternative to commercial Pt/C for practical applications in fuel cells.

Effects of uniaxial compressive strain on the electronic- transport properties of zigzag carbon nanotubes Masato Ohnishi†,*, Ken Suzuki, and Hideo Miura* Tohoku University, Japan † Present address: The University of Tokyo, Japan 1267–1275

There are three stages of the change in electronic transport properties of carbon nanotubes when the uniaxial compressive strain is applied: (a) initial stage, (b) column buckling stage, and (c) shell buckling stage. In particular, because the shell-buckling deformation causes a sudden increase in π-orbital axis angles, which causes a strong localization of density of states, the current drops significantly when the shell buckling is induced into a carbon nanotube.
