Phylogenetic relationship of 16 Oedipodidae species （Insecta： Orthoptera） based on the 16S rRNA gene sequences

引用

Insect Science 2006年第2期13卷 103-108页

作者： hui-meng lu YUAN HUANG College of Life Science Shaanxi Normal University Xi' an China

The sequences of the mitochondrial 16S rRNA gene of 16 Oedipodidae species were amplified and sequenced. All sequences were aligned and analyzed and the phylogenetic relationships were inferred. The properties of 16S gene in Oedipodidae showed typical patterns of many insects such as a high A＋T content and variable distance-dependent transition/transversion ratios. The 0.2 weight for sites of loops may be advisable for phylogeny reconstruction using the maximum parsimony method. The phylogenetic analysis results do not support the current subfamily classification systems of Oedipodidae. Bryodemellinae and Bryodeminae are closely related and should be merged as one subfamily. The status of Oedipodinae and Locustinae is also problematic.

Lithiumsulfur batteries have been intensively studied due to their high theoretical energy density and abundant sulfur resources. However, their commercial application is hindered by the low redox kinetics and high sulfur losses. In principle, in the design of cathodes and separators, the adsorption toward lithium-polysulfides should be enhanced and the conversion of soluble high-order lithium-polysulfides should be catalyzed. Herein, a KV_(3)O_(8)·0.75H_(2)O separator is designed as an effective lithium-polysulfides mediator in lithiumsulfur batteries. The intercalated K+ would enlarge the interlayer spacing of vanadium oxides, preventing the collapse of the layer structure and improving the electrical/ion conductivity of the interface. Moreover, the KV_(3)O_(8)·0.75H_(2)O modified separator possess a prior adsorption and high redox kinetics toward lithium-polysulfides due to the enhanced diffusion kinetics, which guarantees the high-rate capability and efficient utilization of sulfur. As a result, lithiumsulfur batteries exhibit a high capacity of 1362 mAh·g^(-1) and a long lifespan with a low capacity loss of 0.073% per cycle. This work may provide an alternative way to establish a functional separator to balance the adsorption and conversion of polysulfides during the redox back and forth.
