Hypoxia challenges aerobic organisms in numerous environments,and hypoxic conditions may become more severe under future climate-change *** impact of hypoxia on the development of terrestrial insect embryos is not well ***,to address this gap,embryonic life-history traits of migratory locust Locusta migratoria from low-altitude and high-altitude regions were compared under 2 oxygen levels:normoxia(i.e.,21 kPa oxygen partial pressure and mild hypoxia(i.e.,10 kPa oxygen partial pressure).Our results demonstrated that,whether reared under normoxia or mild hypoxia,*** from high-altitude populations had longer developmental times,reduced weight,and lower mean relative growth rate as compared with those from low-altitude *** transferred from normoxia to mild hypoxia,nearly all the tested lifehistory traits presented significant negative changes in the low-altitude populations,but not in the high-altitude *** factor'strain'alone explained 18.26%-54.59%of the total variation for traits,suggesting that the phenotypic differences between *** populations from the 2 altitudes could be driven by genetic *** genetic correlations were found between life-history traits,and most of these showed differentiation between the 2 altitudinal gradients.G-matrix comparisons showed significant structural differences between *** from the 2 regions,as well as several negative covariances(i.e.,trade-offs)between traits in the low-altitude ***,our study provides clear evidence that evolutionary divergence of embryonic traits between *** populations from different altitudes has occurred.

Effect of the synthesis method of SnSb anode materials on their electrochemical properties

Journal of University of Science and Technology Beijing 2007年第4期14卷 345-349页

作者： Chaoli Yin Hailei Zhao Hong Guo xianliang huang Weihua Qiu Department of Inorganic Nonmetallic Materials University of Science and Technology Beijing Beijing 100083 China

SnSb alloy powders for the anode of Li-ion batteries were synthesized by two kinds of reduction precipitation methods： solution titration and rapid mixing. Two kinds of SnSb alloy powders showed different phase compositions and particle morphologies although the same starting materials were used. The SnSb alloy electrode synthesized by titration exhibits high reversible specific capacity and good cycling stability, whereas the rapid-mixing sample shows high irreversible capacity and fast capacity fade. The broad particle size distribution of SnSb powders synthesized by titration is considered to be responsible for the improvement of cycling stability. The initial charge-discharge efficiency exceeding 80% has been obtained for the titration sample. The electrochemical reaction process of two kinds of synthesized SnSb composite electrodes was characterized by cyclic voltammetry and AC impedance techniques.
